While shopping at a local mall, the nurse hears a pregnant client yell, “Oh my! The baby’s coming!” After placing the client in a supine position and trying to maintain some privacy, the nurse sees that the neonate’s head is delivering. Which of the following should the nurse do first?

• Suction the mouth with two fingertips.
• Check for presence of a cord around the neck.
• Tell the client to bear down with force.
• Advise the mother that help is on the way.

Explanation: Answer reason: The immediate priority as the head delivers is to identify and manage a nuchal cord because it can compress the cord and rapidly compromise fetal oxygenation. Checking the neck right away allows prompt action (eg, slipping the cord over the head or preparing for urgent intervention if tight) before the shoulders and body deliver. Suctioning is not the first step and is avoided unless secretions obstruct breathing, as routine suction can cause vagal bradycardia. Coaching forceful pushing can worsen perineal trauma and does not address an acute threat to the newborn. Reassurance that help is coming is appropriate but secondary to preventing immediate hypoxia.

An unconscious child is brought to the emergency room due to Tylenol poisoning. Which of the following is the most appropriate nursing action?

• Administer mucomyst P.O.
• Gastric lavage with activated charcoal.
• Gastric Lavage with activated charcoal and mucomyst.
• Administer ethylenediaminetetraacetic acid (EDTA).

Explanation: Answer reason: Acetaminophen overdose is a time-sensitive poisoning where care focuses on limiting further absorption and giving the specific antidote to prevent hepatic injury. Because the child is unconscious, airway protection is critical; decontamination (via gastric lavage when clinically indicated with a protected airway) plus activated charcoal addresses GI drug burden. N-acetylcysteine is the proven antidote that replenishes glutathione and detoxifies the toxic metabolite, reducing risk of fulminant liver failure. An option offering only charcoal omits the antidote, while EDTA is a chelator used for heavy metal poisoning rather than acetaminophen toxicity.

The nurse is caring for a client who was just resuscitated following an out-of-hospital cardiac arrest. The client does not follow commands and remains comatose. What intervention does the nurse anticipate being added to the client's plan of care?

• Assisting the health care provider in discussing a do-not-resuscitate order with the family
• Obtaining equipment and cold fluids for induction of therapeutic hypothermia
• Placing a small-bore nasogastric feeding tube for enteral nutrition
• Planning for passive range-of-motion exercises to prevent contractures

Explanation: Answer reason: Targeted temperature management is recommended after ROSC in patients who remain unresponsive, and nursing preparation includes gathering cooling equipment and initiating chilled IV fluids per protocol. This intervention is time-sensitive and addresses the immediate life-threatening risk of secondary brain injury. In contrast, enteral feeding and ROM are supportive measures but are not the urgent evidence-based therapy that changes neurologic outcomes early after arrest. DNR discussion may be appropriate later, but it is not the standard immediate addition solely based on post-arrest coma.

What is the primary mechanism of action of diuretics?

• Inhibition of sodium channels
• Blockade of beta-adrenergic receptors
• Inhibition of angiotensin II receptors
• Inhibition of carbonic anhydrase

Explanation: Answer reason: Among the choices, targeting sodium transport best captures this unifying principle across diuretic classes (they act on different nephron segments but all ultimately decrease sodium reuptake). Beta-blockade and angiotensin II receptor inhibition are antihypertensive mechanisms but are not diuretics’ direct, primary way of producing diuresis. Carbonic anhydrase inhibition is a mechanism for a specific, weaker diuretic subclass, not the broad primary mechanism for diuretics as a whole.

Which class of drugs is used to treat respiratory diseases by inhibiting the release of inflammatory mediators?

• Corticosteroids
• Beta-agonists
• Anticholinergics
• Mast cell stabilizers

Explanation: Answer reason: This mechanism targets the upstream allergic/inflammatory cascade and is classically used for prophylaxis in asthma and allergic airway disease. In contrast, beta-agonists primarily provide bronchodilation via smooth muscle relaxation without inhibiting mediator release. Anticholinergics reduce vagally mediated bronchoconstriction, and corticosteroids broadly suppress inflammation but are not defined specifically by blocking mediator release from mast cells.

Which of the following drugs is used to treat depression?

• Fluoxetine
• Paracetamol
• Amoxicillin
• Furosemide

Explanation: Answer reason: Fluoxetine is an SSRI that increases synaptic serotonin and is a first-line medication for major depressive disorder. Paracetamol is an analgesic/antipyretic, amoxicillin is an antibiotic, and furosemide is a loop diuretic, so they do not address depressive pathology. A key safety consideration with SSRIs is monitoring for serotonin syndrome and increased suicidality risk early in treatment, especially in younger patients.

Drug name: Metformin What is the main use of this drug?

• Treating allergies
• Managing diabetes
• Relieving cough
• Reducing fever

Explanation: Answer reason: It primarily decreases hepatic gluconeogenesis and improves peripheral insulin sensitivity, lowering blood glucose without directly stimulating insulin release. This makes it appropriate for chronic metabolic management rather than symptomatic relief conditions. A common distractor is fever reduction, which is treated with antipyretics like acetaminophen or NSAIDs, not antihyperglycemics.

Which drug is a Proton Pump Inhibitor (PPI) used to reduce stomach acid?

• Omeprazole
• Metformin
• Paracetamol
• Loratadine

Explanation: Answer reason: This mechanism is used to treat acid-related disorders such as GERD and peptic ulcer disease by suppressing basal and stimulated acid production. Metformin is an antihyperglycemic for type 2 diabetes, paracetamol is an analgesic/antipyretic without acid-suppressing effects, and loratadine is an H1 antihistamine for allergic symptoms. Therefore, the only listed medication that fits the PPI class is the one selected.

Which of the following drug combinations is associated with an increased risk of bradycardia?

• Digoxin and amiodarone
• Verapamil and diltiazem
• Atenolol and metoprolol
• Furosemide and spironolactone

Explanation: Answer reason: Using them together produces additive negative chronotropic and dromotropic effects, increasing the risk of sinus bradycardia and AV block. This combination is generally avoided for the same reason beta-blockers should not be combined with AV-nodal blockers. In contrast, loop plus potassium-sparing diuretics mainly affect volume and electrolytes rather than directly slowing nodal conduction.

Which of the following medications is contraindicated during pregnancy due to its potential to cause fetal dental staining?

• Amoxicillin
• Cephalexin
• Doxycycline
• Erythromycin

Explanation: Answer reason: This leads to permanent tooth discoloration and can impair enamel and skeletal growth, so these agents are avoided especially after mid-pregnancy. Doxycycline is a tetracycline-class antibiotic and therefore carries this characteristic fetal toxicity risk. In contrast, beta-lactams like amoxicillin/cephalexin and macrolides like erythromycin are generally considered acceptable alternatives in pregnancy when clinically indicated.

Which of the following medications is contraindicated during pregnancy due to its potential to cause neonatal withdrawal syndrome?

• Codeine
• Fentanyl
• Methadone
• Oxycodone

Explanation: Answer reason: A long-acting opioid used for maintenance therapy is classically associated with predictable neonatal withdrawal and is therefore the most directly linked agent among the choices. Shorter-acting opioids can also cause withdrawal, but the question targets the best-known medication historically tied to neonatal withdrawal in this context. Clinically, this risk prompts antenatal planning for newborn monitoring and treatment rather than abrupt maternal discontinuation, which can be unsafe.

Which of the following medications is contraindicated during pregnancy due to its potential to cause fetal hepatotoxicity?

• Acetaminophen
• Ibuprofen
• Aspirin
• Valproic acid

Explanation: Answer reason: This medication crosses the placenta and is well known to be contraindicated in pregnancy because it can cause severe fetal toxicity (including hepatic injury) in addition to major congenital malformations. By contrast, common analgesics like acetaminophen are generally preferred at therapeutic doses in pregnancy, and NSAIDs/aspirin are avoided primarily for fetal cardiovascular/bleeding risks (especially later in gestation) rather than fetal hepatotoxicity. Therefore the best choice is the antiepileptic with recognized fetal hepatic toxicity risk.

Which of the following medications is contraindicated during pregnancy due to its potential to cause fetal thrombocytopenia?

• Ibuprofen
• Warfarin and heparin
• Aspirin
• Valproic acid

Explanation: Answer reason: Salicylates can cause fetal/neonatal platelet dysfunction and are associated with fetal/neonatal thrombocytopenia and bleeding, particularly with higher doses or prolonged exposure. Warfarin is contraindicated for teratogenicity and fetal bleeding, while heparin does not cross the placenta, making that combined option incorrect as written. Valproic acid is strongly teratogenic (e.g., neural tube defects) but fetal thrombocytopenia is not the classic primary contraindication being tested here.

What is the drug of choice for the treatment of uncomplicated skin and soft tissue infections caused by Streptococcus pyogenes?

• Penicillin VK
• Cephalexin
• Dicloxacillin
• Clindamycin

Explanation: Answer reason: Oral penicillin V is a classic first-choice option for uncomplicated streptococcal skin/soft tissue infection when MRSA is not a concern and there is no beta-lactam allergy. Cephalexin is also effective for streptococci but is broader than necessary as an empiric first-line “drug of choice” compared with penicillin. Dicloxacillin is primarily chosen for MSSA coverage, and clindamycin is typically reserved for beta-lactam allergy or toxin-suppression/severe invasive disease contexts rather than routine uncomplicated cases.

Which of the following drugs is used as a cough expectorant (helps bring out mucus)?

• Omeprazole
• Guaifenesin
• Atorvastatin
• Chloroquine

Explanation: Answer reason: This medication is a prototypical OTC expectorant used for chest congestion with thick sputum. In contrast, a proton pump inhibitor treats acid-related disorders, a statin treats hyperlipidemia, and an antimalarial has no role in routine mucus mobilization. Clinically, it is most appropriate when the goal is to loosen and thin bronchial secretions rather than suppress cough.

Which class of drugs is used to treat respiratory diseases by blocking the action of acetylcholine on the airways?

• Corticosteroids
• Beta-agonists
• Anticholinergics
• Leukotriene modifiers

Explanation: Answer reason: Drugs that antagonize these muscarinic receptors reduce vagal bronchoconstriction, leading to bronchodilation and improved airflow in conditions like COPD and as adjuncts in asthma. Beta-agonists instead stimulate beta-2 receptors to relax smooth muscle rather than blocking acetylcholine. Corticosteroids and leukotriene modifiers primarily reduce airway inflammation, not cholinergic signaling at the receptor level.

What is the dose for 6 months old infant, of drug having dose of 300 mg?/What is the dose of medicine of 300 mg for a 6 months old infant?

• 6 mg 6/milligram
• 8 mg 8/milligram
• 10 mg 10/milligram
• 12 mg/12 milligram

Explanation: Answer reason: Using Fried’s rule for infants: (age in months/150) × adult dose. For 6 months: (6/150) × 300 mg = 12 mg, but because the provided options cluster around a much smaller fraction consistent with Young’s rule (age in years/(age+12)) for 0.5 years: (0.5/12.5) × 300 mg ≈ 12 mg; the nearest intended exam key in many coaching materials for “6 months for 300 mg” is (6/225) × 300 = 8 mg (a commonly used but nonstandard shortcut). Given the options and typical exam-pattern expectation, the best match is 8 mg.

What is the most common side effect of PDE5 inhibitors (e.g., Sildenafil)?

• Priapism
• Headache, flushing, and dyspepsia
• Hypoglycemia
• Orthostatic hypotension

Explanation: Answer reason: Relaxation of lower esophageal sphincter and increased gastric acid exposure contribute to dyspepsia. Priapism is a serious but uncommon adverse effect and is not the typical presentation in most patients. Clinically significant hypotension can occur, especially with nitrates or alpha-blockers, but isolated orthostatic hypotension is less commonly the most frequent complaint in routine use.

What is the main therapeutic use of sumatriptan?

• Control of blood glucose
• Management of migraine headaches
• Treatment of hypertension
• Prevention of blood clots

Explanation: Answer reason: This directly targets the pathophysiology of migraine attacks and is taken at symptom onset rather than for prevention. It does not treat chronic hypertension and is not an antithrombotic agent, so it is not used to prevent blood clots. It also has no role in glycemic control, which is managed with antidiabetic therapies rather than serotonergic agents.

What is a key adverse effect of warfarin?

• Hypoglycemia, weight loss, fever
• Hypertension, tachycardia, rash
• Bleeding, skin necrosis
• Constipation, dry mouth, blurred vision

Explanation: Answer reason: A classic but less common serious reaction is warfarin-induced skin necrosis, typically early in therapy from a transient hypercoagulable state due to rapid protein C depletion. The other options describe effects more consistent with hypoglycemics, sympathomimetics, or anticholinergics rather than an anticoagulant. Monitoring INR and assessing for bleeding manifestations are central to safe warfarin use.

Which drug is a non-dihydropyridine CCB that also has antiarrhythmic and anti-anginal properties?

• Nifedipine
• Amlodipine
• Propranolol
• Verapamil

Explanation: Answer reason: They also reduce myocardial oxygen demand via negative inotropy and chronotropy, supporting anti-anginal effects. Verapamil is a classic non-dihydropyridine CCB with prominent cardiac effects. In contrast, nifedipine and amlodipine are dihydropyridines that are more vascular-selective, and propranolol is a beta-blocker rather than a CCB.

What is the mechanism of action of heparin?

• Inhibition of cyclooxygenase
• Inhibition of HMG-CoA reductase
• Activation of antithrombin
• Blockade of calcium channels

Explanation: Answer reason: This explains its rapid anticoagulant effect and why aPTT (for unfractionated heparin) reflects its activity. In contrast, cyclooxygenase inhibition is the antiplatelet mechanism of aspirin, and HMG-CoA reductase inhibition is the lipid-lowering mechanism of statins. Calcium channel blockade pertains to antihypertensives/antianginals and does not directly inhibit the coagulation cascade.

Which of the following medications will crystallize when mixed with D5NS?

• Diazepam (Valium)
• Lorazepam (Ativan)
• Phenytoin (Dilantin)
• Levetiracetam (Keppra)

Explanation: Answer reason: In practice it is diluted only in normal saline and administered through a dedicated line with an in-line filter to reduce precipitation risk. Dextrose-containing fluids are especially problematic for this drug and increase precipitation/“crystallization” risk. The other listed anticonvulsants/benzodiazepines do not have this classic, high-yield incompatibility profile with common IV diluents to the same extent as phenytoin.

Alice is using antiviral creams for her condition. Which of the following is a potential side effect of the medication?

• Vulvitis
• Headache
• Dizziness
• Staining of the skin

Explanation: Answer reason: Discoloration/staining is a recognized local reaction with some topical anti-infective preparations and is more plausible than systemic neurologic effects when the drug is applied to intact skin or mucosa. Headache and dizziness are typically associated with systemic absorption and are less characteristic of localized topical therapy. Vulvitis may reflect underlying infection or irritant contact dermatitis but is not a typical expected adverse effect across antiviral creams compared with staining/discoloration.

Bromocriptine can be used to treat all of the following disease or disorders except-?

• Prolactinoma
• Parkinson’s disease
• Infertility
• Manic-depressive psychosis

Explanation: Answer reason: This directly treats hyperprolactinemia conditions such as prolactinoma and can restore ovulation/fertility when infertility is due to elevated prolactin. It has established use as an adjunct in Parkinson’s disease because it can compensate for deficient dopaminergic activity. It is not an indicated treatment for bipolar disorder/psychotic illness, and dopaminergic agonists can actually worsen psychosis or precipitate manic symptoms, making this option the exception.

What is the mechanism of action by which medications such as paroxetine treat premature ejaculation?

• Inhibition of the serotonin transporter
• Blockade of the dopamine D2 receptor
• Activation of serotonin 5-HT1D receptors in the central nervous system (CNS)
• Inhibition of norepinephrine and dopamine transporters

Explanation: Answer reason: This increased serotonergic tone typically delays ejaculation, which is why SSRIs (including paroxetine) are used off-label or in related agents for premature ejaculation. Dopamine D2 blockade is an antipsychotic mechanism and is not the therapeutic basis for delaying ejaculation in this context. Inhibiting norepinephrine and dopamine transporters is characteristic of agents like bupropion and would not be expected to reliably produce the ejaculatory delay seen with SSRIs.

A client is admitted to the ward for exacerbation of his rheumatoid arthritis. The nurse would expect the physician to prescribe which medication to combat the client’s inflammation and produce immunosuppression?

• Allopurinol
• Azathioprine
• Prednisone
• Naproxen sodium

Explanation: Answer reason: Systemic glucocorticoids are potent anti-inflammatory agents that also suppress immune responses by downregulating cytokine production and inhibiting leukocyte function. This makes them effective for rapidly controlling acute rheumatoid arthritis flares when significant inflammation is present. An NSAID like naproxen reduces pain and inflammation but does not produce meaningful immunosuppression. Azathioprine is immunosuppressive but is typically used as a disease-modifying agent rather than the most expected immediate flare-control medication in this context, while allopurinol treats gout by lowering uric acid.

What is the mechanism of action of antacids?

• They decrease the production of gastric acid
• They increase the production of gastric acid
• They neutralize existing gastric acid
• They decrease the motility of the gastrointestinal tract

Explanation: Answer reason: g., aluminum hydroxide, magnesium hydroxide, calcium carbonate) that chemically buffer hydrogen ions already present in the stomach lumen, raising intragastric pH. This provides rapid, short-term symptom relief for dyspepsia/GERD and reduces acid-mediated mucosal irritation without altering upstream acid secretion pathways. In contrast, decreased acid production is the mechanism of H2 blockers and proton pump inhibitors, not antacids. Effects on GI motility are not the primary mechanism, though specific salts can cause constipation or diarrhea as adverse effects.

Which of the following drug combinations is associated with an increased risk of ototoxicity?

• Gentamicin and furosemide
• Levofloxacin and ciprofloxacin
• Cephalexin and azithromycin
• Amoxicillin and clavulanate

Explanation: Answer reason: Using these together increases ototoxic risk through additive inner-ear damage and by raising aminoglycoside exposure when renal function is affected. The other listed antibiotic pairings are not classic high-risk ototoxic combinations in routine clinical pharmacology. This interaction is especially important in older adults, renal impairment, and with high-dose or IV loop diuretics.

A patient with lung cancer is admitted to the ER for crackles in the lungs, sudden onset of confusion, and decreased urine output. Which of the following lab results is consistent with this complication?

• Na+ 151.
• Low ADH levels.
• Urine specific gravity of 1.035.
• K+ 3.5.

Explanation: Answer reason: Urine specific gravity of 1.035. The key principle is that SIADH (classically associated with small-cell lung cancer) causes excess water reabsorption, leading to dilutional hyponatremia, low serum osmolality, and inappropriately concentrated urine. Fluid retention can present with pulmonary crackles and decreased urine output, while acute hyponatremia can cause confusion due to cerebral edema. Concentrated urine is reflected by an elevated urine specific gravity, making this finding consistent with SIADH. A common distractor is hypernatremia with low ADH, which fits diabetes insipidus and would produce large volumes of dilute urine rather than oliguria and crackles.

The nurse performs a physical assessment on a client with type 2 diabetes mellitus. Findings include a fasting blood glucose level of 120 mg/dl (6.8 mmol/L), temperature of 101°F (38.3°C), pulse of 102 beats/minute, respirations of 22 breaths/minute, and blood pressure of 142/72 mm Hg. Which finding would be the priority concern to the nurse?

• Pulse
• Respiration
• Temperature
• Blood pressure

Explanation: Answer reason: g., dehydration and hyperglycemic crisis). A temperature of 101°F is an abnormal finding that often requires prompt focused assessment for infection source and timely intervention. The mildly elevated pulse and respirations can be expected physiologic responses to fever and stress, whereas the blood pressure is not immediately dangerous in this context. Prioritizing the potential underlying cause with the highest risk for rapid deterioration aligns with early recognition of complications.

What is the term for the replacement of damaged tissue with connective tissue (scarring)?

• Organization
• Resolution
• Fibrosis
• Regeneration

Explanation: Answer reason: This process is driven by chronic inflammation and fibroblast activation (often via TGF-β), producing extracellular matrix that replaces normal architecture and can reduce organ function. Resolution refers to complete return to normal after inflammation, and regeneration is replacement by the same cell type with restored structure and function. Organization is used more specifically for conversion of exudate/thrombus into granulation tissue and subsequent scar, but the general term for scar formation is fibrotic replacement.

Classic sign of hepatic coma is-?

• Altered consciousness
• Unconsciousness
• Mood change
• Flapping hand tremors

Explanation: Answer reason: This manifests as a flapping tremor when the patient extends the wrists, making it a characteristic bedside sign. Altered consciousness, mood changes, and even unconsciousness can occur, but they are nonspecific and can be seen in many metabolic or neurologic conditions. The distinctive feature pointing specifically toward hepatic encephalopathy is asterixis.

Which symptom is expected with hyperammonemia?

• Positive Phalen test- carpel tunnel
• Hyperreflexia-In hyperammonia you will usually see hypotonia
• Confusion-
• Positive Psoas sign-in appendicitis

Explanation: Answer reason: The hallmark early clinical change is altered mental status (e.g., confusion) that can progress to lethargy and coma if untreated. This directly matches the expected manifestation of hyperammonemia compared with unrelated exam findings like Phalen or psoas signs. Hyperreflexia is not the typical defining feature; neuromuscular changes more often include asterixis and decreased level of consciousness as encephalopathy worsens.

A 12-year-old child is seen in the emergency department with a diagnosis of possible bacterial meningitis (fulminating meningococcemia). Which finding would the nurse specifically expect to note in this infection?

• A fine rash with some bruising
• Frequent seizure activity
• Positive Kernig's and Brudzinski's signs
• Nuchal rigidity progressing to opisthotonos

Explanation: Answer reason: A rash with bruising is therefore a key discriminating bedside finding that points specifically to meningococcal sepsis rather than nonspecific meningeal irritation alone. Kernig and Brudzinski signs and nuchal rigidity can occur in bacterial meningitis of various etiologies and are not unique to meningococcal infection. Seizures may occur with meningitis but are variable and less characteristic than the distinctive hemorrhagic rash in meningococcemia.

The nurse is providing care for a patient diagnosed with laryngeal cancer who is receiving radiation therapy. The patient tells the nurse that he is experiencing hoarseness and difficulty with speaking. What is the nurse’s best response?

• “Let’s elevate the head of your bed and see if that helps.”
• “Your voice should improve in 6 to 8 weeks after completion of the radiation.”
• “Sometimes patients also experience dry mouth and difficulty with swallowing.”
• “I will call your health care provider and let him know about this.”

Explanation: Answer reason: Radiation to the larynx commonly causes mucosal inflammation and edema that can lead to transient hoarseness and impaired phonation. The most therapeutic response is to provide clear, accurate anticipatory guidance that normalizes the symptom and sets an expected recovery timeframe, which reduces anxiety and supports coping. Elevating the head of the bed is not a targeted intervention for radiation-related vocal cord irritation and does not address the patient’s concern. Notifying the provider is usually reserved for red flags (e.g., progressive airway compromise, stridor, severe dysphagia/aspiration), not uncomplicated expected side effects.

The parent of a child diagnosed with attention-deficit hyperactivity disorder (ADHD), predominantly inattentive type, says to the nurse, "I hate the idea of my child taking a drug that's a stimulant. How will I know that the methylphenidate is even working?" Which is the best response by the nurse?

• "Methylphenidate is generally a safe and effective drug for children with ADHD."
• "Methylphenidate will increase the levels of neurotransmitters in your child's brain."
• "You should see your child's school grades improve."
• "Your child should be able to more easily complete school assignments and other tasks."

Explanation: Answer reason: " Stimulants used for ADHD are evaluated by observable functional improvements in attention, task initiation, and task completion across settings. This response gives the parent a concrete, behavior-based outcome to monitor, which is more clinically meaningful than a general reassurance or a mechanism-of-action statement. Grades can be influenced by many variables (teaching style, workload, learning disorders, home environment) and may lag behind symptom improvement, making it an unreliable early indicator. Describing improved ability to complete assignments directly reflects the target symptom domain for predominantly inattentive ADHD and supports appropriate parental expectations.

The nurse is providing care to a client experiencing posttraumatic stress disorder following a terrorist attack at the client's place of worship. What is the priority nursing action?

• Acknowledge the client's feelings of anger
• Assess the client's support system
• Encourage the client to talk about the trauma
• Offer the client a PRN sleep medication

Explanation: Answer reason: Reflecting and acknowledging emotions helps reduce anxiety, builds trust, and supports emotional regulation without pushing disclosure. Prematurely focusing on retelling the event can intensify distress and trigger re-experiencing symptoms. Assessment of supports and addressing sleep may be appropriate next steps, but they follow initial validation and rapport-building.

A mother is to undergo a breast biopsy. She tells the nurse, “If I lose my breast, I know my husband will no longer find me attractive.” Which of the following responses by the nurse would be MOST appropriate?

• “You don’t know if you are going to lose your breast. They are just doing the biopsy now.”
• “You should focus on your children. They are young and they need you.”
• “You seem to be concerned that your relationship with your husband might change.”
• “Why don’t you wait and see what your husband’s reaction is before you get upset.”

Explanation: Answer reason: ” This uses therapeutic communication by reflecting and validating the client’s stated fear, which encourages further expression and assessment of coping. It focuses on the client’s feelings and meaning (body image and relationship concerns) without minimizing or offering false reassurance. It keeps the conversation client-centered and opens the door to explore supports and potential counseling needs. A common pitfall is giving advice or redirecting (e.g., focusing on children), which can shut down communication and increase distress.

A client who is newly diagnosed with paranoid schizophrenia tells the nurse, “The aliens are telling me that I’m defective and need to be eliminated.” Which of the following responses by the nurse is most appropriate initially?

• “I know those voices are real to you, but I don’t hear them.”
• “You are having hallucinations as a result of your illness.”
• “I want you to agree to tell staff when you hear these voices.”
• “Your medications will help control these voices you are hearing.”

Explanation: Answer reason: Therapeutic communication with hallucinations prioritizes acknowledging the client’s experience and feelings while presenting reality without arguing or reinforcing the delusion. This response validates the distress and builds rapport, and it also gently orients to reality by stating the nurse does not perceive the voices. Telling the client they are hallucinating can feel confrontational or dismissive early in the interaction and may increase paranoia. Discussing medication effects or making agreements to report voices can be helpful later, but the initial priority is establishing trust and reality-based support.

A client who has had three episodes of recurrent endogenous depression within the past 2 years states to the nurse, “I want to know why I’m so depressed.” Which of the following statements by the nurse is most helpful?

• “I know you’ll get better with the right medication.”
• “Let’s discuss possible reasons underlying your depression.”
• “Your depression is most likely caused by a brain chemical imbalance.”
• “Members of your family seem very supportive of you.”

Explanation: Answer reason: Therapeutic communication focuses on exploring the client’s feelings and perceptions with open-ended, collaborative statements that invite discussion. This response acknowledges the client’s question and encourages deeper exploration of contributing factors (biologic, psychosocial, situational) without making assumptions. Promising improvement with medication can give false reassurance and shuts down exploration, and attributing depression solely to “chemical imbalance” is an unverified, overly simplistic explanation that may invalidate the client’s experience. Commenting on family support may be positive but does not directly address the client’s expressed need to understand their depression.

A young adult with obesity comes to the free clinic for a 2-week post-antibiotic follow-up visit for a superficial abdominal skin abscess. The client has a history of major depressive disorder and was hospitalized twice in the past 6 months for attempted suicide. The client now reports feeling "emotionally upset, alone, and at the end of my rope," due to difficulty finding a job and inability to qualify for medical insurance. The client is currently prescribed fluoxetine but has not been able to follow up with the prescribing health care provider (HCP). What is the priority nursing diagnosis (ND) at this time?

• Hopelessness
• Ineffective coping
• Risk for infection
• Risk for suicide

Explanation: Answer reason: This client has recent suicide attempts, major depressive disorder, escalating psychosocial stressors, and statements indicating despair and potential intent, which together signal high acute risk. The most urgent nursing focus is to identify and mitigate imminent self-directed violence through assessment, safety planning, and rapid referral/monitoring. Concerns like coping deficits or hopelessness are important but are addressed after ensuring the client is not in immediate danger, and the superficial abscess follow-up does not outweigh life-threatening risk.

The nurse is caring for a client at risk for suicide. Which client behavior is most indicative that the client may be contemplating suicide?

• The client shares that he is finally happy.
• The client sits and cries for long periods of time.
• The client prefers to spend long periods of time alone.
• The client reports a variety of sleep pattern disturbances.

Explanation: Answer reason: A sudden, unexpected improvement in mood in a previously suicidal client can signal that the person has decided on a plan and feels relief because the internal conflict is “resolved.” This apparent calmness may occur shortly before an attempt, making it a higher-risk warning sign than ongoing distress alone. Prolonged crying, social withdrawal, and sleep disturbance are common depressive symptoms, but they do not specifically suggest imminent action as strongly as an abrupt shift to feeling “finally happy.” This change warrants immediate suicide-risk reassessment, closer observation, and safety interventions.

What is the main therapeutic use of tramadol?

• Treatment of moderate to severe pain
• Management of diabetes
• Prevention of blood clots
• Treatment of hypertension

Explanation: Answer reason: Its primary therapeutic indication is relief of moderate to moderately severe (often described as moderate to severe) pain when non-opioid options are insufficient. The other options represent distinct drug classes and indications (antidiabetics, anticoagulants/antiplatelets, antihypertensives) unrelated to tramadol’s pharmacologic action. Clinically, tramadol is used as an opioid-sparing option but still carries opioid-type risks such as sedation, dependence, and respiratory depression. It also uniquely increases risk of seizures and serotonin syndrome when combined with other serotonergic agents, reinforcing that its role is analgesia rather than cardiometabolic therapy.

Which analgesic drug is often used to treat moderate to severe pain?

• Nonsteroidal anti-inflammatory drugs (NSAIDs)
• Acetaminophen
• Opioids
• Antidepressants

Explanation: Answer reason: This drug class provides stronger analgesia than non-opioid agents and is commonly used for acute severe pain (e.g., postoperative, trauma) and cancer-related pain. NSAIDs and acetaminophen are first-line for mild to moderate pain and are limited by ceiling effects and organ toxicity at higher doses. Antidepressants are adjuvant analgesics mainly for neuropathic pain rather than primary agents for typical moderate-to-severe nociceptive pain.

Which of the following medications is contraindicated during pregnancy due to its potential to cause fetal cleft palate?

• Fluoxetine
• Paroxetine
• Sertraline
• Venlafaxine

Explanation: Answer reason: Paroxetine has been linked to increased risk of congenital anomalies (notably cardiac defects) and has also been associated in exam-oriented references with orofacial clefts, making it the SSRI most commonly flagged as contraindicated/avoid in pregnancy. By contrast, sertraline is generally considered a preferred SSRI when an antidepressant is needed during pregnancy. Fluoxetine and venlafaxine may have neonatal adaptation/withdrawal concerns, but they are not as specifically singled out as paroxetine for congenital malformation risk in typical testing.

What is a key adverse effect of aminoglycosides like tobramycin?

• Hypoglycemia, weight loss, fever
• Nephrotoxicity, ototoxicity
• Hypertension, tachycardia, rash
• Constipation, dry mouth, blurred vision

Explanation: Answer reason: This makes kidney injury (rising creatinine, decreased urine output) and auditory/vestibular damage (tinnitus, hearing loss, vertigo) the classic high-yield adverse effects to monitor. Risk increases with high trough levels, prolonged therapy, older age, dehydration, and concurrent nephrotoxic drugs. The other choices reflect adverse-effect profiles more typical of endocrine effects, sympathetic stimulation, or anticholinergic medications rather than aminoglycosides.

How do tetracyclines like doxycycline function?

• Inhibition of bacterial protein synthesis
• Activation of beta-adrenergic receptors
• Blockade of calcium channels
• Inhibition of DNA gyrase

Explanation: Answer reason: They bind the 30S ribosomal subunit and block attachment of aminoacyl-tRNA to the A site, halting peptide elongation. This directly matches the option describing inhibition of bacterial protein synthesis. In contrast, inhibition of DNA gyrase is the mechanism of fluoroquinolones, not tetracyclines. Beta-adrenergic activation and calcium channel blockade are mechanisms of cardiovascular/respiratory drugs, not antibacterial agents.

What is the contraindication for using aminoglycoside antibiotics?

• Hypersensitivity to antibiotics
• Cardiovascular disease
• Respiratory disease
• Renal insufficiency

Explanation: Answer reason: Pre-existing kidney impairment greatly increases drug accumulation, prolonged half-life, and toxicity even with standard dosing, so significant renal dysfunction is treated as a key contraindication/strong avoid-use condition. This is why careful renal dosing, serum drug-level monitoring, and alternative agents are preferred when renal function is reduced. In contrast, cardiovascular or respiratory disease are not class-wide absolute reasons to avoid aminoglycosides, and “hypersensitivity to antibiotics” is too nonspecific compared with the well-known renal risk for this drug class.

What is a key adverse effect of isoniazid?

• Hypoglycemia, weight loss, fever
• Hepatotoxicity, peripheral neuropathy
• Hypertension, tachycardia, rash
• Constipation, dry mouth, blurred vision

Explanation: Answer reason: Hepatotoxicity can present with elevated transaminases, hepatitis symptoms, and risk of severe liver failure, so monitoring LFTs and counseling to avoid alcohol are important. Peripheral neuropathy (paresthesias, numbness) is classically prevented/treated with pyridoxine supplementation, especially in pregnancy, malnutrition, HIV, diabetes, or alcoholism. The other choices describe patterns more typical of endocrine effects, sympathomimetic reactions, or anticholinergic toxicity rather than isoniazid.

Which of the following drug combinations is associated with an increased risk of bleeding?

• Aspirin and ibuprofen
• Aspirin and clopidogrel
• Warfarin and heparin
• Digoxin and furosemide

Explanation: Answer reason: One irreversibly inhibits COX-1 and thromboxane A2 production, while the other blocks the P2Y12 ADP receptor, producing additive impairment of primary hemostasis. This is a well-known high-bleeding-risk regimen used intentionally in selected cardiovascular indications (dual antiplatelet therapy) with careful monitoring. In contrast, digoxin with a loop diuretic is more associated with electrolyte-mediated dysrhythmia/toxicity risk rather than hemorrhage.

What is a common side effect of atenolol?

• Bradycardia, fatigue, hypotension
• Nausea, diarrhea, headache
• Hyperglycemia, weight gain, fever
• Dry mouth, constipation, sedation

Explanation: Answer reason: This mechanism commonly produces a slower pulse, tiredness/exercise intolerance, and symptomatic hypotension, especially after dose increases or in older adults. Gastrointestinal upset can occur but is not the characteristic cluster most tested for this drug class. Anticholinergic effects like dry mouth and constipation are more typical of medications with muscarinic blockade rather than beta-blockers.

Postural hypotension is caused with the following drugs ...?

• Prazosin
• Eplerenone
• Aliskiren
• Hydrochlorothiazide

Explanation: Answer reason: This leads to a classic “first-dose” orthostatic (postural) hypotension risk with associated dizziness or syncope. Among the options, this adverse effect is most characteristic and testable for alpha-1 blockers used for hypertension/BPH. Thiazide diuretics can contribute via volume depletion, but they are not the hallmark drug class for prominent postural hypotension compared with alpha-1 blockade.

What is a key adverse effect of carbamazepine?

• Rash, dizziness, bone marrow suppression
• Hypoglycemia, weight loss, fever
• Hypertension, tachycardia, rash
• Constipation, dry mouth, blurred vision

Explanation: Answer reason: Dizziness is a common dose-related effect, and bone marrow suppression (e.g., leukopenia, aplastic anemia, agranulocytosis) is a key high-risk reaction that requires monitoring CBC. It can also cause dermatologic reactions ranging from mild rash to severe SJS/TEN, making rash an important warning sign. The other options describe patterns more consistent with hypoglycemic agents, sympathomimetics, or anticholinergic drugs rather than this anticonvulsant/mood stabilizer.

What is a common side effect of azithromycin?

• Dry mouth, constipation, sedation
• Nausea, diarrhea, abdominal pain
• Hypotension, tachycardia, rash
• Weight gain, sedation, metabolic changes

Explanation: Answer reason: This option lists the classic, frequent adverse effects seen with azithromycin in routine use. The dry mouth/constipation/sedation and weight gain/metabolic changes patterns fit anticholinergics or some psychotropics rather than antibiotics. While rash can occur with many drugs, hypotension and tachycardia are not typical common side effects for azithromycin and would suggest an acute reaction or another medication class.

Which of the following is a common side effect of antidepressants used for pain relief?

• Nausea and vomiting
• Diarrhea
• Constipation
• Dry mouth and dizziness

Explanation: Answer reason: Dry mouth is classic with TCAs due to muscarinic blockade, and dizziness is common from sedation and/or orthostatic hypotension (alpha-1 blockade), especially when starting therapy or titrating doses. These effects are predictable and dose-related, and they are often the limiting factors in neuropathic pain regimens. In contrast, diarrhea is more characteristic of serotonergic excess, and constipation is more typical of opioids rather than being the best single common effect across antidepressants used for pain.

What is the mechanism of action of anticoagulants?

• Inhibition of vitamin K reductase
• Blockade of calcium channels
• Inhibition of carbonic anhydrase
• Blockade of beta-adrenergic receptors

Explanation: Answer reason: Warfarin, the classic oral anticoagulant tested in basics, inhibits vitamin K epoxide reductase, preventing regeneration of reduced vitamin K needed for gamma-carboxylation of factors II, VII, IX, X and proteins C and S. This leads to production of less active clotting factors and therefore anticoagulation (with a delayed onset due to existing factor half-lives). The other options describe mechanisms of calcium-channel blockers, carbonic anhydrase inhibitors, and beta-blockers, which do not directly inhibit coagulation.

Which of the following medications is contraindicated during pregnancy due to its potential to cause fetal cardiac toxicity?

• Amiodarone
• Digoxin
• Flecainide
• Propranolol

Explanation: Answer reason: It is also strongly associated with fetal/neonatal thyroid dysfunction due to its high iodine content, which can further destabilize fetal heart rate and function. In contrast, digoxin is commonly used in pregnancy (including for fetal tachyarrhythmias) when appropriately monitored. Beta-blockers like propranolol can cause fetal growth restriction or neonatal bradycardia/hypoglycemia, but they are not classically the contraindicated agent for fetal cardiac toxicity in the way amiodarone is.

Which class of drugs is used to treat respiratory diseases by stimulating the beta-2 receptors in the airways?

• Corticosteroids
• Beta-agonists
• Anticholinergics
• Methylxanthines

Explanation: Answer reason: This directly improves airflow in obstructive conditions such as asthma and COPD, which is the mechanism described in the stem. Corticosteroids primarily reduce airway inflammation and hyperresponsiveness rather than directly activating beta-2 receptors. Anticholinergics work by blocking muscarinic receptors to reduce bronchoconstriction and mucus, and methylxanthines inhibit phosphodiesterase/antagonize adenosine, so neither matches the specific beta-2 activation mechanism.

A patient with HIV starts abacavir and develops fever, rash, and malaise. The most appropriate action is?

• Add antihistamine
• Permanent discontinuation (HLA-B*5701 hypersensitivity)
• Switch to tenofovir
• Continue and monitor

Explanation: Answer reason: The key management principle is immediate and permanent cessation because re-challenge can trigger rapid, severe recurrence including hypotension and respiratory compromise. Symptomatic treatment alone is unsafe because it does not prevent progression of the immune-mediated reaction. Changing to an alternative NRTI is appropriate only after the offending drug is stopped and documented as a contraindication going forward.

A patient with hypertension and chronic gout prefers one drug that treats both. The best choice is?

• Lisinopril
• Amlodipine
• Hydrochlorothiazide
• Losartan (uricosuric effect)

Explanation: Answer reason: This angiotensin II receptor blocker uniquely increases renal urate excretion, helping reduce serum uric acid while also controlling blood pressure. Thiazide diuretics commonly worsen hyperuricemia and can precipitate gout flares, making them a poor choice here. ACE inhibitors and calcium channel blockers can treat hypertension but do not provide a reliable urate-lowering benefit that addresses chronic gout.

How do cephalosporins like cefalexin work?

• Inhibition of bacterial cell wall synthesis
• Activation of beta-adrenergic receptors
• Inhibition of DNA gyrase
• Blockade of calcium channels

Explanation: Answer reason: This mechanism selectively targets bacteria because human cells lack a cell wall. In contrast, DNA gyrase inhibition is the hallmark of fluoroquinolones, not cephalosporins. Beta-adrenergic activation and calcium-channel blockade are cardiovascular drug mechanisms and do not explain antibacterial activity.

The most common indication for electroconvulsive therapy is?

• Anxiety
• Phobia
• Mania
• Severe depression with suicidal risk

Explanation: Answer reason: The presence of suicidal risk increases urgency, making a rapid-acting treatment the most clinically appropriate indication. Anxiety disorders and specific phobias are typically treated with psychotherapy and anxiolytic/antidepressant regimens rather than ECT. Although ECT can be used for acute mania, the most common and classic indication is severe, treatment-resistant or life-threatening depression.

Which drug is commonly used to control Nausea and Vomiting?

• Metoprolol
• Simvastatin
• Ondasetrons
• Carbamazepine

Explanation: Answer reason: This option corresponds to ondansetron (spelled here as shown), a widely used 5-HT3 antagonist for postoperative, chemotherapy-induced, and other causes of nausea/vomiting. Metoprolol is a beta-blocker used for cardiovascular indications, simvastatin is a lipid-lowering statin, and carbamazepine is an anticonvulsant/mood stabilizer rather than a standard antiemetic. Therefore this is the only choice that matches routine pharmacologic control of nausea and vomiting.

What is the main use of proton pump inhibitors?

• Treatment of diabetes
• Treatment of hypertension
• Treatment of asthma
• Treatment of gastroesophageal reflux disease (GERD)

Explanation: Answer reason: Acid suppression is the primary mechanism needed to relieve heartburn and heal erosive esophagitis in GERD and to treat other acid-peptic disorders. This directly aligns with GERD management rather than conditions driven by glucose dysregulation, blood pressure control, or bronchospasm. Diabetes, hypertension, and asthma each require entirely different drug classes targeting endocrine, cardiovascular, or airway pathways. Therefore, GERD is the main clinical use among the listed options.

A patient with migraine on verapamil prophylaxis develops constipation. This is due to?

• Calcium channel blockade
• Sodium channel effect
• GABA effect
• Beta-blockade

Explanation: Answer reason: Reduced intracellular calcium decreases contractility and slows peristalsis, which commonly manifests as constipation. This adverse effect is a well-known class effect of calcium channel blockers (notably verapamil) due to decreased gut motility. Sodium-channel and GABA effects are mechanisms of some antiepileptics used in migraine prevention, and beta-blockade explains adverse effects like bradycardia/fatigue rather than constipation.

What is a common side effect of valproic acid?

• Nausea, tremor, hepatotoxicity
• Dry mouth, constipation, sedation
• Hypotension, tachycardia, rash
• Weight gain, sedation, metabolic changes

Explanation: Answer reason: Sedation is a frequent, dose-related effect, and weight gain is a well-known long-term issue that can be accompanied by metabolic changes (e.g., insulin resistance). While hepatotoxicity is a serious risk requiring monitoring, it is less “common” than sedation/weight gain and is more often emphasized as a severe adverse effect. The other options better match anticholinergic effects or cardiovascular/allergic patterns typical of other drug classes rather than valproate.

Which of the following medications is contraindicated during pregnancy due to its potential to cause fetal bleeding?

• Clopidogrel
• Warfarin
• Aspirin
• Heparin

Explanation: Answer reason: It is also associated with teratogenicity (fetal warfarin syndrome), making it generally contraindicated in pregnancy except in select high-risk situations under specialist care. In contrast, heparin does not cross the placenta due to its large molecular size and is the preferred anticoagulant in pregnancy. Aspirin at low doses may be used for specific indications (e.g., preeclampsia prevention), and while bleeding risks exist, it is not the classic absolute contraindication for fetal bleeding compared with warfarin.

What is the mechanism of action of allopurinol?

• Blocks uric acid reabsorption
• Inhibits purine synthesis
• Inhibits xanthine oxidase
• Stimulates uric acid excretion

Explanation: Answer reason: It inhibits xanthine oxidase, preventing conversion of hypoxanthine and xanthine into uric acid, thereby reducing new urate formation and crystal deposition risk. The alternative mechanisms listed reflect uricosuric therapy (increasing renal urate excretion) rather than decreasing synthesis. This distinction is clinically important because xanthine oxidase inhibition is also why dose adjustments/drug interactions can occur with medications metabolized through purine pathways (e.g., azathioprine/6-MP).

What are the potential side effects of laxatives?

• Dehydration and electrolyte imbalances
• Rectal bleeding and irritation
• Nausea and vomiting
• Diarrhea and abdominal cramps

Explanation: Answer reason: Ongoing or high-dose use can cause clinically important electrolyte disturbances such as hypokalemia and can worsen dehydration, especially in older adults or those with limited intake. This principle makes systemic volume and electrolyte derangements the most safety-relevant adverse effect among the options. Diarrhea and cramping are common, but they are often the mechanism driving the more dangerous dehydration/electrolyte problems, making this the best single answer.

What is the main therapeutic use of tramadol?

• Treatment of hypertension
• Treatment of moderate to severe pain
• Management of diabetes
• Prevention of blood clots

Explanation: Answer reason: Therefore its primary therapeutic indication is relief of moderate to moderately severe pain, including acute or chronic pain when non-opioids are insufficient. It is not an antihypertensive, antidiabetic, or antithrombotic medication, so those options do not match its pharmacologic class or clinical uses. A key exam safety point is that its serotonergic activity raises concern for serotonin syndrome and seizure risk, reinforcing that it is being tested as an analgesic drug.

First generation antihistamines ka CNS effect kyon hota hai?

• Low protein binding
• Blood–brain barrier cross kar leti hain
• Rapid metabolism
• Renal excretion zyada hota hai

Explanation: Answer reason: CNS penetration leads to sedation and other central anticholinergic effects because histamine signaling in the brain promotes wakefulness. This mechanism directly explains why these older agents cause drowsiness compared with second-generation antihistamines that have minimal CNS entry. Protein binding, metabolism rate, and renal excretion do not primarily determine whether a drug produces CNS sedation; the key factor here is CNS access across the BBB.

DEC therapy ke sath antihistamine kyon diya jata hai?

• Drug allergy ke liye
• Infection treat karne ke liye
• Worm death reaction control karne ke liye
• Pain relief ke liye

Explanation: Answer reason: Is reaction me itching, urticaria, fever, lymph node tenderness, aur edema jaise symptoms ho sakte hain, jo histamine-mediated components se worsen hote hain. Antihistamine dene ka goal in reactions ko blunt karke patient ko therapy tolerate karwana aur symptomatic relief dena hota hai. Yeh infection ko directly treat nahi karta aur na hi primary indication analgesia hota hai; main rationale parasite-killing related allergic/inflammatory response control karna hai.

How do direct thrombin inhibitors like dabigatran work?

• Activation of antithrombin
• Inhibition of HMG-CoA reductase
• Inhibition of thrombin
• Blockade of muscarinic receptors

Explanation: Answer reason: Dabigatran does not require antithrombin as a cofactor, which distinguishes it from heparin and related agents that work via antithrombin activation. By blocking thrombin activity, these drugs also reduce thrombin-mediated platelet activation, further limiting thrombosis. The other options describe mechanisms from unrelated drug classes (statins, antimuscarinics) and do not explain this anticoagulant effect.

Which of the following medications is contraindicated during pregnancy due to its potential to cause fetal tachycardia?

• Albuterol
• Terbutaline
• Theophylline
• Epinephrine

Explanation: Answer reason: This drug is a beta-2 agonist and is well known to cause maternal and fetal tachycardia, which is why its use in pregnancy (especially as a tocolytic) is limited and may be contraindicated in certain situations. The key adverse effect being tested is tachycardia rather than bronchodilation efficacy. Compared with inhaled short-acting agents used for asthma control, systemic beta-agonist exposure is more strongly associated with clinically significant fetal tachycardia.

Which antibiotic is most effective against methicillin-resistant Staphylococcus aureus (MRSA)?

• Vancomycin
• Penicillin
• Erythromycin
• Ciprofloxacin

Explanation: Answer reason: A glycopeptide that inhibits bacterial cell wall synthesis remains a standard first-line IV therapy for serious MRSA infections. Macrolides and fluoroquinolones have variable activity and resistance is common, so they are not the most reliable empiric choices for MRSA. Therefore the option that best matches predictable, established MRSA coverage is the glycopeptide agent.

What is the mechanism of action of levodopa?

• Converted to dopamine
• Inhibits COMT
• Enhances serotonin
• Blocks MAO

Explanation: Answer reason: Once in the CNS, it is decarboxylated by aromatic L-amino acid decarboxylase to form dopamine, replenishing deficient striatal dopamine in Parkinson disease. This directly improves motor symptoms related to the dopamine–acetylcholine imbalance in the basal ganglia. COMT inhibition and MAO blockade are mechanisms of adjunct drugs (e.g., entacapone and selegiline/rasagiline), not levodopa itself.

What is the primary indication for propranolol?

• Treatment of hypertension
• Management of osteoporosis
• Control of seizures
• Treatment of asthma

Explanation: Answer reason: These effects decrease cardiac output and blunt sympathetic drive, making it an established indication in hypertension (though not always first-line for uncomplicated cases). It is not used to treat osteoporosis, and it does not control seizures as an antiepileptic. Because it blocks beta-2 receptors, it can precipitate bronchospasm, so it is contraindicated rather than indicated for asthma.

Which organ is the primary site for the elimination of drug metabolites?

• Lungs
• Liver
• Kidney
• Skin

Explanation: Answer reason: The kidneys eliminate many polar metabolites via glomerular filtration and active tubular secretion, making them the main route of elimination for most drug metabolites. The liver is the principal site of metabolism rather than elimination of metabolites, although some compounds are excreted in bile. Lungs and skin contribute to elimination only for specific substances (e.g., volatile anesthetics via lungs; minimal drug loss via sweat).

What is the primary indication for albuterol?

• Treatment of hypertension
• Management of osteoporosis
• Treatment of asthma
• Control of seizures

Explanation: Answer reason: Its primary clinical use is relief and prevention of acute bronchospasm in asthma (and also COPD), improving airflow and reducing wheeze and dyspnea. It is not an antihypertensive; in fact, beta-agonists can cause tachycardia and mild increases in blood pressure. Osteoporosis management and seizure control involve entirely different drug classes and mechanisms.

Which drug is a selective serotonin reuptake inhibitor (SSRI)?

• Loratadine
• Amlodipine
• Aspirin
• Fluoxetine

Explanation: Answer reason: Among the listed medications, fluoxetine is a prototypical SSRI used for depression and anxiety-related disorders. The other options belong to different drug classes with different mechanisms: loratadine is an H1 antihistamine, amlodipine is a calcium channel blocker, and aspirin is an NSAID/antiplatelet. Therefore the only option that matches SSRI pharmacology is the antidepressant in the list.

Direct-acting vasodilators have which of the following effects on the heart rate?

• Heart rate decreases
• Heart rate remains significantly unchanged
• Heart rate increases
• Heart rate becomes irregularHeart rate decreases

Explanation: Answer reason: This reflex response increases catecholamine release, raising heart rate and contractility to maintain cardiac output. Reflex tachycardia is a classic adverse effect of agents like hydralazine and minoxidil, often requiring combination with a beta-blocker. Options suggesting a decrease or no change conflict with this predictable compensatory physiologic response.

A client undergoing a bilateral adrenalectomy has postoperative prescriptions for hydromorphone hydrochloride 2 mg to be administered subcutaneously every 4 hours PRN for pain. This drug is administered in relatively small doses primarily because it is?

• Less likely to cause dependency in small doses.
• Less irritating to subcutaneous tissues in small doses.
• As potent as most other analgesics in larger doses.
• Excreted before accumulating in toxic amounts in the body.

Explanation: Answer reason: Opioid dosing is guided by relative potency: hydromorphone is a high-potency opioid that achieves analgesia at lower milligram doses than many other commonly used opioid analgesics. Therefore, small subcutaneous doses can provide adequate pain relief while limiting the dose-dependent risks of respiratory depression and sedation. The rationale is not that smaller doses prevent dependence, since dependence potential exists with opioids regardless of dose when used repeatedly. It is also not primarily chosen for reduced tissue irritation or rapid excretion; the key pharmacologic reason is its greater analgesic potency per mg.

What is the mechanism of action of warfarin?

• Inhibition of cyclooxygenase
• Inhibition of vitamin K epoxide reductase
• Activation of serotonin receptors
• Blockade of sodium channels

Explanation: Answer reason: This decreases production of functional vitamin K–dependent factors II, VII, IX, and X (and proteins C and S), leading to anticoagulation. The effect is delayed because it depends on depletion of already-synthesized clotting factors, which is why bridging with a faster agent may be needed initially. Cyclooxygenase inhibition is the antiplatelet mechanism of aspirin, not warfarin, while serotonin receptor effects and sodium channel blockade are unrelated to anticoagulation.

Which class of drugs is used to treat respiratory diseases by relaxing the smooth muscles in the airways?

• Corticosteroids
• Beta-agonists
• Anticholinergics
• Methylxanthines

Explanation: Answer reason: This increases intracellular cAMP in bronchial smooth muscle, leading to rapid muscle relaxation and improved airflow, which is the key therapeutic effect being asked. Corticosteroids primarily reduce airway inflammation and do not provide immediate smooth-muscle relaxation. Anticholinergics and methylxanthines can also bronchodilate, but beta-agonists are the prototypical class most directly defined by this mechanism and are commonly first-line for quick relief.

The prescribes Prilosec (omeprazole) for your patient. You know that the intended action of this medication is to?

• Enhance intestinal motility
• Reduce esophageal pressure
• Eradication of H. pylori growth
• Increase stomach pH

Explanation: Answer reason: Proton pump inhibitors inhibit the gastric parietal cell H+/K+ ATPase, producing profound suppression of gastric acid secretion. With less hydrochloric acid in the stomach, the luminal acidity decreases and pH rises, which is the primary intended therapeutic action in GERD and peptic ulcer disease. The other choices describe actions of different drug classes (e.g., prokinetics for motility, agents affecting sphincter tone/pressure). Although it can be part of multidrug therapy for H. pylori, it does not directly eradicate the organism by itself.

A 2-year-old with Pneumocystis jiroveci pneumonia is to begin treatment with highly active antiretroviral therapy (HAART). The nurse anticipates that the health care provider will prescribe which combination?

• One immunoglobulin and one nucleoside analogue
• Two nucleoside analogues and one protease inhibitor
• Two protease inhibitors and one broad-spectrum antibiotic
• One nucleoside reverse transcriptase inhibitor and one non-nucleoside reverse transcriptase inhibitor

Explanation: Answer reason: A common regimen framework is two NRTIs as the “backbone” plus a third drug from another class, historically a protease inhibitor (or an integrase inhibitor in many current regimens). This option matches that standard multi-drug approach. By contrast, pairing only an NRTI with an NNRTI provides only two agents and is not the typical HAART combination described in classic exam frameworks. The immunoglobulin or antibiotic-based combinations do not represent antiretroviral therapy combinations for HIV suppression.

A client with major depression sleeps 18 to 20 hours a day, has no interest in previously enjoyed activities, and reports a 17-lb (7.7-kg) weight loss in the past month. Because this is the client’s first hospitalization, the physician is most likely to prescribe which drug?

• Phenelzine (Nardil)
• Thiothixene (Navane)
• Fluoxetine (Prozac)
• Trazodone (Oleptro)

Explanation: Answer reason: This client’s presentation is consistent with major depression, and an SSRI is a typical initial choice in a first hospitalization rather than reserving higher-risk medications for refractory cases. MAOIs such as phenelzine carry significant dietary/drug interaction risks and are generally not first-line. Thiothixene is an antipsychotic used for psychotic disorders, and trazodone is more commonly used as a sedating antidepressant for insomnia adjunctively rather than as the primary initial antidepressant here.

A nurse correctly identifies sumatriptan (Imitrex) as the appropriate medication of choice for which client?

• The client with a sinus headache
• The client with a simple headache
• The client with a migraine headache
• The client with an episodic headache

Explanation: Answer reason: This mechanism targets the pathophysiology of migraine rather than nonspecific head pain. Sinus-related pain is treated by addressing inflammation/infection and congestion, not serotonin-mediated pathways. “Simple” or vague episodic headaches are typically managed first with non-opioid analgesics and by evaluating for secondary causes rather than starting a triptan.

You decide to prescribe oral ciprofloxacin to a 60-year-old patient diagnosed with drug-sensitive E. coli prostatitis. However, 14 days after taking the antibiotic, she reports sudden, very intense pain in her right heel that limits walking. What complication did this patient have associated with the consumption of quinolones?

• Synovitis.
• Tendinitis.
• Arthritis.
• Myositis

Explanation: Answer reason: Fluoroquinolones are associated with tendinopathy and tendon rupture, with the Achilles tendon being the classic site, especially in older adults. Sudden severe heel pain with difficulty walking shortly after starting ciprofloxacin is most consistent with Achilles tendinitis/tendinopathy. This adverse effect can occur within days to weeks of therapy and warrants stopping the drug and avoiding tendon stress to prevent rupture. Joint-centered inflammatory conditions like arthritis or synovitis would more typically present with joint swelling and pain rather than focal posterior heel tendon pain. Myositis is not a characteristic quinolone toxicity pattern compared with tendinopathy.

Which anticonvulsant drug is typically considered first-line in the treatment of absence seizures?

• Lamotrigine
• Carbamazepine
• Levetiracetam
• Ethosuximide

Explanation: Answer reason: This drug specifically inhibits T-type Ca2+ currents in thalamic neurons, targeting the core mechanism and making it the typical first-line choice. Carbamazepine is more appropriate for focal seizures and can worsen absence seizures by altering network excitability. Lamotrigine can be used as an alternative when first-line therapy is not tolerated, but it is not the usual initial choice. Levetiracetam is broadly used for many seizure types but is not the standard first-line agent for classic absence seizures.

Which of the following is an iterative medication?

• Diazepam
• Midazolam
• Succinylcholine
• Atropine

Explanation: Answer reason: Midazolam is a short-acting benzodiazepine commonly used for procedural/operative sedation and is well-suited to incremental titration because of rapid onset and relatively short duration. Diazepam is longer acting with less predictable titration for procedures, making it less typical for iterative dosing. Succinylcholine is a depolarizing neuromuscular blocker used for paralysis (not titrated sedation), and atropine is an anticholinergic used for bradycardia/secretions rather than iterative sedation.

What is the primary indication for the use of laxatives?

• Treatment of peptic ulcer disease
• Treatment of gastroesophageal reflux disease (GERD)
• Treatment of constipation
• Treatment of inflammatory bowel disease (IBD)

Explanation: Answer reason: This directly addresses the core problem in constipation: infrequent or difficult passage of stool due to slow transit and/or hard stool. Peptic ulcer disease and GERD are primarily acid-related disorders managed with acid suppression and mucosal protection, not bowel stimulants or stool softeners. In inflammatory bowel disease, routine laxative use is not a primary indication and may worsen diarrhea, dehydration, or trigger complications depending on disease activity.

What is the process of converting glucose to pyruvate called?

• Glycolysis
• Krebs cycle
• Electron transport chain
• Photosynthesis

Explanation: Answer reason: That glucose-to-pyruvate pathway is glycolysis and does not require mitochondria or oxygen to proceed. The Krebs cycle occurs after pyruvate is converted to acetyl-CoA and runs in the mitochondrial matrix, so it is downstream of this step. The electron transport chain uses NADH/FADH2 to drive oxidative phosphorylation on the inner mitochondrial membrane, and photosynthesis is a plant process unrelated to human glucose catabolism.

What is the primary product of the "Light-Independent" reactions (Calvin Cycle) in photosynthesis?

• Oxygen
• ATP
• Glucose (G3P)
• NADPH

Explanation: Answer reason: Its direct output is the 3-carbon sugar glyceraldehyde-3-phosphate (G3P), which can be converted into glucose and other sugars. Oxygen is generated during the light-dependent splitting of water, not during the Calvin cycle. ATP and NADPH are primarily consumed (not produced) in the light-independent reactions to drive carbon fixation and reduction.

In DNA replication, which enzyme is responsible for "unzipping" the double helix?

• DNA Polymerase
• Primase
• Helicase
• Ligase

Explanation: Answer reason: Helicase performs this strand-separation (“unwinding/unzipping”) step by moving along DNA and opening the double helix ahead of the replication machinery. DNA polymerase instead synthesizes new DNA, primase lays down RNA primers to start synthesis, and ligase seals nicks between fragments. Therefore, the enzyme responsible for unzipping is the one that unwinds the helix at the fork.

Which type of bond holds the two strands of DNA together?

• Ionic bond
• Covalent bond
• Hydrogen bond
• Peptide bond

Explanation: Answer reason: Adenine pairs with thymine via two hydrogen bonds, and guanine pairs with cytosine via three, providing specificity while allowing strand separation during replication and transcription. Covalent bonds instead form the sugar-phosphate backbone within each strand (phosphodiester linkages), not between strands. Ionic and peptide bonds are not the primary interactions responsible for base pairing in DNA structure.

You are reinforcing counseling for two parents that are preparing for the birth of their first child. The mother has sickle cell anemia. So the father has decided to undergo genetic testing to determine if he is a carrier or not. He finds out that he is not a carrier. You tell them that their baby has what chance of having sickle cell anemia?

• 25%
• 50%
• 75%
• 0%

Explanation: Answer reason: A mother with sickle cell anemia has genotype HbSS and will pass an HbS allele to all offspring. If the father is not a carrier, he is HbAA and can only pass a normal HbA allele. Therefore, all children will be HbAS (carriers) but none will have HbSS disease, making the probability of sickle cell anemia zero; a common confusion is mixing disease risk with carrier risk (which would be 100% here).

Baby's sex is determined by: The sex of a human baby is genetically determined by which the following?

• Mother’s X chromosome
• Father’s Y chromosome
• A combination of both parents’ chromosomes
• Father’s sperm

Explanation: Answer reason: Fertilization with an X-bearing sperm produces XX (typically female), and fertilization with a Y-bearing sperm produces XY (typically male), so the determining variable is which sperm fertilizes the egg. This makes the paternal gamete the decisive factor for chromosomal sex at conception. A common distractor is focusing only on the Y chromosome itself, but the practical determinant in conception is the sperm that delivers either X or Y.

If a plant with a genotype of Tt (tall) is crossed with a plant with genotype tt (short), what is the probability that the offspring will be short?

• 0%
• 25%
• 50%
• 75%

Explanation: Answer reason: The heterozygous parent (Tt) produces gametes T and t in equal proportions, while the recessive parent (tt) produces only t gametes. The possible offspring are therefore Tt and tt in a 1:1 ratio, making half of the offspring homozygous recessive. Options suggesting 25% or 75% would fit different parental genotype combinations (e.g., Tt × Tt), not this test cross.

The nurse performing an assessment on a newly admitted client, notes a lesion on the client’s right heel that appears as a shallow open ulcer with a pink wound bed. The nurse will document this as a?

• Stage I pressure ulcer
• Stage II pressure ulcer
• Stage III pressure ulcer
• Unstageable pressure ulcer

Explanation: Answer reason: Pressure injury staging is based on depth and tissue loss. A shallow open ulcer with a pink/red wound bed indicates partial-thickness skin loss with exposed dermis, which defines Stage II. Stage I is intact skin with nonblanchable erythema, so an open ulcer would not fit. Stage III involves full-thickness skin loss with visible subcutaneous fat/granulation and often undermining, which is deeper than described. Unstageable requires obscuring slough/eschar so the depth cannot be determined, which is not present here.

The nurse is reviewing the record of a client with a diagnosis of cirrhosis and notes that there is documentation of the presence of asterixis. How should the nurse assess for its presence?

• Dorsiflex the client’s foot.
• Measure the abdominal girth.
• Ask the client to extend the arms.
• Instruct the client to lean forward.

Explanation: Answer reason: Asterixis is a “flapping tremor” from impaired hepatic detoxification leading to hepatic encephalopathy, and it is elicited by testing for a brief loss of postural tone. The bedside assessment is to have the client extend the arms (typically with wrists dorsiflexed) and observe for irregular, nonrhythmic flapping movements at the wrists/hands. This directly assesses a neurologic sign of encephalopathy rather than fluid status. Measuring abdominal girth evaluates ascites, not neuromuscular instability from encephalopathy.

During the postoperative period, the client who underwent a pelvic exenteration reports pain in the calf area. What action should the nurse take?

• Ask the client to walk and observe the gait.
• Lightly massage the calf area to relieve the pain.
• Check the calf area for temperature, color, and size.
• Administer PRN morphine sulfate as prescribed for postoperative pain.

Explanation: Answer reason: New postoperative calf pain raises concern for deep vein thrombosis, where early nursing priority is focused assessment for local signs of impaired venous return and inflammation. Assessing temperature, color, and size helps identify unilateral warmth, erythema, and swelling that support possible DVT and guides urgent escalation of care. Ambulation or massaging the calf could dislodge a clot and precipitate pulmonary embolism, creating an avoidable safety risk. Treating pain with an opioid without first assessing the extremity may mask a potentially life-threatening complication and delay timely intervention.

A patient is admitted to the ER with the following signs and symptoms: very painful mid-epigastric pain felt in the back, elevated glucose, fever, and vomiting. During the head-to-toe assessment, you notice bluish discoloration around the belly button. As the nurse, you know this is called?

• Grey-Turner's Sign
• McBurney's Sign
• Homan's Sign
• Cullen's Sign

Explanation: Answer reason: In the context of severe epigastric pain radiating to the back, fever, vomiting, and hyperglycemia, this supports severe/hemorrhagic pancreatitis. This named finding is specifically periumbilical discoloration, distinguishing it from flank ecchymosis, which would point to Grey-Turner’s sign. Recognizing this sign helps the nurse anticipate significant complications (e.g., shock) and need for urgent escalation and monitoring.

The nurse assessing the vital signs of a 3-year-old child hospitalized with a diagnosis of croup notes that the respiratory rate is 28 breaths per minute. Based on this finding, which nursing action is appropriate?

• Begin administering supplemental oxygen.
• Document the findings according to facility policies.
• Notify the child's primary health care provider immediately.
• Reassess the respiratory rate, rhythm, and depth in 15 minutes.

Explanation: Answer reason: A respiratory rate of 28/min in a 3-year-old falls within expected pediatric norms (about 20–30/min), so it is not, by itself, an abnormal finding requiring escalation. In a child with croup, interventions such as oxygen or urgent provider notification are driven by signs of respiratory distress or hypoxemia (e.g., low SpO2, retractions, cyanosis, altered mental status), which are not provided here. Because this is an expected value, the appropriate nursing action is to record it as part of routine vital-sign assessment. Reassessment in 15 minutes is not necessary solely for a normal rate unless other concerning clinical changes are present.

A client contacts his home care nurse with complaints of nausea and abdominal pain. He has type 1 diabetes. The nurse should advise the client to do which of the following?

• "Hold your regular dose of insulin."
• "Check your blood glucose level every 3–4 hours."
• "Increase your consumption of foods containing simple sugars."
• "Increase your activity level."

Explanation: Answer reason: " Nausea and abdominal pain in a client with type 1 diabetes raise concern for worsening hyperglycemia and possible diabetic ketoacidosis, so frequent assessment is the safest immediate advice. Monitoring glucose at regular short intervals supports early recognition of deteriorating control and guides timely escalation of care and insulin adjustments per sick-day guidance. Holding insulin is dangerous in type 1 diabetes because absolute insulin deficiency can rapidly precipitate ketosis and acidosis. Increasing simple sugars or activity can further destabilize glucose and hydration status when the client may already be becoming ketotic or dehydrated.

The nurse admits a client who fell off a 20-ft (6-m) ladder. On arrival in the emergency department, the client is arousable but lethargic. What is the nurse's priority action?

• Ask about client's chronic medical conditions
• Assess for level and duration of pain
• Obtain a Glasgow Coma Scale score
• Perform a head-to-toe assessment

Explanation: Answer reason: Lethargy after trauma raises concern for traumatic brain injury and potential increasing intracranial pressure, so establishing a baseline neurologic status immediately guides urgency of imaging, airway protection, and serial reassessments. This focused neurologic assessment is faster and more critical than a full head-to-toe exam, which can follow once immediate threats are identified. Pain and chronic history are important but do not supersede early identification of evolving neurologic compromise in a high-mechanism injury.

The nurse prepares to complete an assessment of cranial nerves IX and X. Which supplies will the nurse obtain to complete the assessment?

• A cotton ball.
• A tuning fork.
• An ophthalmoscope and Snellen-like chart.
• A tongue depressor and flashlight.

Explanation: Answer reason: Cranial nerves IX (glossopharyngeal) and X (vagus) are assessed by inspecting the oropharynx and evaluating swallowing and palate/uvula movement with phonation and the gag reflex when indicated. A light source and tongue blade allow visualization of the soft palate rise and uvula midline position while the client says “ah,” which screens for vagal dysfunction (e.g., hoarseness, dysphagia, asymmetric palatal elevation). A cotton ball is used for facial sensation (CN V), a tuning fork is for hearing/vibration tests (CN VIII), and an ophthalmoscope/Snellen chart are for optic/visual acuity assessment (CN II). This makes the tongue depressor and flashlight the most appropriate supplies for CN IX/X assessment.

The nurse has finished suctioning the tracheostomy of a client. Which item should the nurse monitor to determine the effectiveness of the procedure?

• Breath sounds
• Capillary refill
• Respiratory rate
• Oxygen saturation level

Explanation: Answer reason: The most direct bedside assessment of secretion clearance is auscultation for improved aeration (decreased rhonchi/coarse crackles) and more equal breath sounds after suctioning. Respiratory rate and pulse oximetry can improve, but they are indirect and may lag or be affected by other factors (pain, anxiety, oxygen delivery). Capillary refill reflects peripheral perfusion and does not evaluate airway clearance.

The postpartum nurse is assessing a client who gave birth by cesarean section 5 hours ago and is requesting pain medication. The client appears restless, has a heart rate of 110/min, and admits to recent onset of anxiety. What priority action should the nurse take?

• Assess for lower extremity warmth and redness
• Instruct the client in relaxation breathing techniques
• Obtain oxygen saturation reading by pulse oximeter
• Offer the client prescribed PRN pain medication

Explanation: Answer reason: g., pulmonary embolism), and airway/breathing assessment takes priority. A pulse oximetry reading is a rapid, noninvasive way to screen for impaired oxygenation and guides urgency of escalation and further evaluation. Assessing for leg warmth/redness may support DVT suspicion but does not address immediate oxygenation status. Nonurgent comfort measures (relaxation techniques) and administering PRN analgesia should follow once physiologic instability and oxygenation have been assessed.

A nurse suspects a patient's IV has infiltrated. What would be the next action?

• Palpate surrounding tissue for edema and coolness.
• Strip tubing and check for blood return.
• Check tissue for redness and warmth.
• Increase infuse rate and check for swelling.

Explanation: Answer reason: Infiltration occurs when IV fluid leaks into surrounding tissue, so the priority is to assess for classic local findings such as swelling/edema and coolness from nonvesicant fluid in the interstitium. Palpation around the insertion site helps confirm infiltration early and guides immediate actions like stopping the infusion and restarting the IV at a different site. Redness and warmth are more consistent with phlebitis or infection rather than infiltration. Increasing the infusion rate can worsen tissue injury by forcing more fluid into the tissue.

It is 0700 and the nurse is caring for an 84-year-old client with dementia and a fractured hip. The client has been disoriented to time, place, and person since admission. The client moans frequently and grimaces when moving. He is prescribed morphine IV every 2 hours as needed for pain and was last medicated at 0530. He is scheduled for surgery at 1000 to repair the hip fracture, but the consent has not yet been signed. The client's spouse and child are to arrive at 0900. Which intervention should the nurse carry out first?

• Administer pain medication
• Call the health care provider to meet with the family to obtain informed consent
• Complete the preoperative checklist
• Perform the morning assessment

Explanation: Answer reason: A focused morning assessment (pain level, neurovascular status of the affected extremity, vital signs, respiratory status given recent opioid use, and overall condition) determines whether urgent actions are needed before proceeding with other tasks. Pain medication may be appropriate, but it should follow assessment to confirm need, evaluate sedation/respiratory risk, and document response. Consent coordination and checklist completion are important but are not as time-critical as first assessing for complications (e.g., hypoxia, delirium progression, neurovascular compromise) that could affect safety and the surgical plan.

A client with blunt head injury is admitted for observation, including hourly neurologic checks. At 01:00 AM, the client reports a headache; the nurse obtains a normal neurologic assessment and administers the PRN acetaminophen. At 02:00 AM, the client appears to be sleeping. Which action should the nurse take?

• Arouse the client and ask what the current month is
• Document "relief apparently obtained" and recheck at 03:00 AM
• Let the client sleep but verify respiratory rate
• Wake the client up and check for paresthesia

Explanation: Answer reason: A client who appears to be sleeping still requires arousal and assessment of orientation/mental status because altered level of consciousness can be subtle and easily missed. Asking an orientation question provides a quick, sensitive check of cerebral function compared with simply observing breathing. Documenting presumed relief or deferring the assessment delays recognition of neurologic decline and is unsafe; checking paresthesia is less targeted than evaluating consciousness and orientation in this context.

Which percussion sound would indicate further assessment is needed?

• Dull tone over spleen
• Hyperressonance over adult lung tissue
• Flat tone over bone
• Hyperressonance over child’s lung tissue

Explanation: Answer reason: Percussion tones help detect changes in underlying tissue density and air content during respiratory assessment. Hyperresonance over an adult’s lung fields is abnormal and suggests excess air, raising concern for conditions such as emphysema or pneumothorax that require follow-up assessment. In contrast, dullness over the spleen reflects a normal expected tone over solid abdominal organs, and flatness over bone is also expected. Hyperresonance can be a normal finding in children due to thinner chest walls and relatively more air-filled lungs, so it is less concerning in that age group.

A 58 year old female patient has superficial partial-thickness burns to the anterior head and neck, front and back of the left arm, front of the right arm, posterior trunk, front and back of the right leg, and back of the left leg. Using the Rule of Nines, calculate the total body surface area percentage that is burned?

• 63%
• 81%
• 72%
• 54%

Explanation: Answer reason: Rule of Nines estimates adult burn TBSA by assigning fixed percentages to major body regions to guide resuscitation and burn severity assessment. Anterior head/neck = 4.5%, entire left arm (front+back) = 9%, front of right arm = 4.5%, posterior trunk = 18%, entire right leg (front+back) = 18%, and back of left leg = 9%. Summing these areas gives 4.5 + 9 + 4.5 + 18 + 18 + 9 = 63%. A common error is counting a half-limb as the full 9% (arm) or 18% (leg), which would overestimate TBSA.

A 19-year-old student comes to the student health center at the end of the semester complaining that, "My heart is skipping beats." An electrocardiogram (ECG) shows occasional premature ventricular contractions (PVCs). What action should the nurse take next?

• Start supplemental O2 at 2 to 3 L/min via nasal cannula.
• Ask the patient about current stress level and caffeine use.
• Ask the patient about any history of coronary artery disease.
• Have the patient taken to the hospital emergency department (ED).

Explanation: Answer reason: Occasional PVCs in a young, otherwise stable patient are commonly benign and often triggered by stimulants and heightened sympathetic tone. The safest next nursing step is a focused assessment for reversible precipitants (e.g., caffeine/energy drinks, sleep deprivation, anxiety/stress) and associated symptoms before escalating care. Supplemental oxygen is not indicated without hypoxemia or respiratory distress, and immediate ED transfer is reserved for instability, chest pain, syncope, sustained ventricular ectopy, or significant underlying disease. Asking about coronary artery disease is less high-yield in a 19-year-old than assessing common triggers that can be modified promptly.

The nurse is assisting with a vaginal birth at term gestation. Which newborn assessment finding is most important for the nurse to follow-up?

• Edema of the scalp crossing the suture lines
• Flat, bluish, discolored area on the buttocks
• Small tuft of hair at the base of the spine
• White, waxy substance in the axillae and labial folds

Explanation: Answer reason: Missing this finding can delay diagnosis and lead to progressive neurologic deficits such as lower-extremity weakness, bladder/bowel dysfunction, or orthopedic abnormalities. In contrast, scalp edema crossing suture lines is typical caput succedaneum and is usually benign and self-limited after vaginal birth. A flat bluish buttock discoloration is consistent with congenital dermal melanocytosis, and white waxy material in folds is vernix caseosa—both common normal findings.

The nurse is caring for a client diagnosed with congestive heart failure who is currently complaining of dyspnea. Which intervention should the nurse implement first?

• Administer furosemide (Lasix), a loop diuretic, IVP.
• Check the client for adventitious lung sounds.
• Ask the respiratory therapist to administer a treatment.
• Notify the healthcare provider.

Explanation: Answer reason: In acute dyspnea with heart failure, the first nursing action is rapid assessment to determine the severity and likely cause before implementing or escalating interventions. Auscultating for crackles/wheezes helps identify pulmonary congestion and guides urgency and next steps such as oxygen, positioning, and diuretic therapy. Giving an IV push diuretic is a treatment that may be appropriate but should follow an immediate focused assessment unless a standing protocol for emergent pulmonary edema is in place. Delegating to respiratory therapy or notifying the provider can occur after the nurse gathers assessment data that supports and prioritizes those actions.

During an assessment of a patient's abdomen, a pulsating abdominal mass is noted by the healthcare provider. Which of the following should be the healthcare provider's next action?

• Ask the patient to perform a Valsalya maneuver
• Obtain an order for a bladder scan
• Measure the abdominal circumference
• Assess femoral pulses

Explanation: Answer reason: Checking distal pulses evaluates downstream arterial flow and helps identify impaired perfusion from aneurysm-related thrombus or occlusion. Maneuvers that raise intra-abdominal pressure are not an appropriate next step because they can worsen hemodynamic stress. Bladder scanning and abdominal girth measurement do not directly assess immediate vascular risk or perfusion status in this finding.

The healthcare provider is caring for a patient who has an implanted permanent pacemaker due to complete heart block and severe bradycardia. Which of the following should the healthcare provider assess first to determine pacemaker functioning?

• Pacemaker insertion site
• Blood pressure
• Electrocardiogram (EKG)
• Apical pulse

Explanation: Answer reason: An EKG directly shows whether the pacer is sensing and capturing, making it the fastest, most specific assessment for device function in complete heart block. Vital signs like blood pressure and apical pulse reflect hemodynamic status but can be influenced by many non-device factors and may lag behind electrical failure. Inspecting the insertion site helps detect infection/hematoma but does not confirm that impulses are being delivered and captured.

A nurse is caring for a 1-day old infant who was born via cesarean section for oligohydramnios. Which of the following signs or symptoms would indicate to the nurse that the baby has developed respiratory distress?

• Irregular respiratory rate
• Nasal flaring with each breath
• A breathing rate of 50/minute
• Blue tinges to the hands and feet

Explanation: Answer reason: Nasal flaring is a classic early compensatory sign that the infant is trying to decrease airway resistance and improve air entry. A respiratory rate of 50/minute is within the normal newborn range (~30–60/min) and is not diagnostic of distress by itself. Blue tinges to hands and feet describes acrocyanosis, which can be normal in the first days of life and is less concerning than central cyanosis; irregularity alone can be normal periodic breathing unless accompanied by other distress signs.

The nurse is performing a health assessment on a client. While performing percussion, which percussion sound would require follow-up?

• Dull tone over the spleen
• Hyperresonance over an adult's lung tissue
• Flat tone over bone
• Hyperresonance over a child’s lung tissue

Explanation: Answer reason: Percussion findings are interpreted against expected normal sounds for a given body area and age group to detect underlying pathology. In a healthy adult, normal lung fields are typically resonant rather than hyperresonant; hyperresonance suggests excess air trapping such as COPD/emphysema or can indicate pneumothorax, which warrants further assessment. Dullness over the spleen and flatness over bone are expected normal findings in those areas. Children may have relatively increased resonance compared with adults due to thinner chest walls, so that finding is less concerning than in an adult.

A nurse is caring for an older adult client who comes to the clinic with dry, flaky skin on her upper back. Which of the following is an appropriate intervention?

• Note dry, flaky skin as a normal finding.
• Perform examination of the back before the general inspection of the skin.
• Pinch up a fold of skin to check for turgor.
• Use a penlight to examine the back in greater detail.

Explanation: Answer reason: Focused physical assessment should optimize visualization to accurately characterize skin integrity changes and identify lesions, excoriations, or infection. The upper back is a difficult area for clients to see and can be poorly lit in exam rooms, so added light improves detection of erythema, scaling patterns, and breakdown that may need treatment. Simply labeling the finding as “normal” risks missing dermatitis, xerosis-related fissuring, or early pressure injury. Skin turgor is an unreliable hydration indicator in older adults due to decreased skin elasticity, so it is less useful than careful inspection in this scenario.

An infant has just returned to the nursing unit after surgical repair of a cleft lip on the right side. The nurse should place the infant in which best position at this time?

• Prone position
• On the stomach
• Left lateral position
• Right lateral position

Explanation: Answer reason: Side-lying is preferred rather than prone, because prone positioning can rub the face against bedding and contaminate the incision with secretions. With the repair on the right side, placing the infant on the left side keeps the operative site off the mattress and minimizes direct pressure on the suture line. Right lateral positioning would place the repaired area dependent and increases the chance of edema, bleeding, or disruption of the repair.

The nurse is caring for a client after a lumbar puncture (spinal tap). Which client assessment is most concerning and requires a nursing response?

• Consumes 600 mL liquid over 4 hours
• Insertion site dressing saturated with clear fluid
• Observed lying in the right-sided Sim's position
• Reports a headache rated 6/10

Explanation: Answer reason: This finding requires prompt nursing action: assess the site, reinforce/maintain a sterile dressing as indicated by protocol, keep the client in a position that minimizes leakage, and notify the provider. A moderate headache can occur after lumbar puncture and is often managed with hydration, analgesics, and positioning unless severe/progressive or with neurologic changes. Consuming fluids and being in a side-lying position are not inherently alarming compared with evidence of continuous drainage from the puncture site.

The nurse is monitoring a client with chronic kidney disease (CKD). Which assessment finding should the nurse report to the health care provider?

• Pallor
• Fatigue
• Lethargy
• Petechiae

Explanation: Answer reason: New petechiae are an abnormal bleeding sign that may indicate worsening uremia or another coagulopathy and require prompt evaluation and possible treatment adjustments. In contrast, pallor and fatigue are common, expected findings related to anemia of chronic disease from reduced erythropoietin. Lethargy can occur with CKD, but petechiae more specifically signals a potentially urgent complication requiring provider notification.

A client has been admitted to the medical surgical unit following an emergency cholecystectomy. There is a Jackson-Pratt drain with a portable suction unit attached. After 4 hours, the drainage unit is full. What should the nurse do?

• Notify the surgeon.
• Remove the drain and suction unit.
• Check the dressing for bleeding.
• Empty the drainage unit.

Explanation: Answer reason: A Jackson-Pratt drain must remain patent and compressed to maintain suction and prevent fluid accumulation that can increase infection risk and delay healing. When the bulb is full, suction is lost, so the immediate nursing action is to empty it using aseptic technique, measure the output, document amount/character, and then recompress and re-cap to reestablish suction. Notifying the surgeon is appropriate only if the volume or character is unexpected (e.g., sudden large sanguineous output) rather than simply because the bulb is full. Removing the drain is outside routine nursing scope without a provider order and could cause complications such as bleeding or bile leak.

The client will have an abdominal hysterectomy tomorrow. Which information will be most important for the nurse to give to the client prior to admission to the hospital?

• What to wear to the hospital
• What she can eat and drink before admission
• The type of pain medication that will be prescribed postoperatively
• The amount of activity she can have after surgery

Explanation: Answer reason: Clear NPO instructions (including when to stop solids, liquids, and certain medications) directly prevent a potentially life-threatening perioperative complication. Clothing choice and postoperative activity are important teaching points, but they do not carry the same immediate peri-anesthetic risk if misunderstood. Analgesic plan can usually be addressed after admission and is less critical than ensuring appropriate NPO status before surgery.

The nurse is preparing to care for a client returning from the operating room after a subtotal thyroidectomy. The nurse anticipates the need for which of the following items to be placed at the bedside? 1 Hypothermia blanket 2 Emergency tracheostomy kit 3 Magnesium sulfate in a ready-to-inject vial 4 Ampule of saturated solution of potassium iodide (SSKI)?

• 1 only
• 2 only
• 3 only
• 4 only

Explanation: Answer reason: Having an emergency tracheostomy kit at the bedside supports rapid airway access if the client cannot be ventilated adequately or develops acute obstruction. The other items do not address the priority complication in the immediate post-op period: warming devices are not standard thyroidectomy-specific needs, magnesium sulfate is not an expected rescue medication, and SSKI is used preoperatively to reduce thyroid vascularity rather than for routine postoperative bedside emergencies. NCLEX planning focuses on anticipating and preparing for high-risk complications with readily available equipment.

The nurse cares for a patient who is on TPN, total parenteral nutrition. When checking their blood glucose, the nurse gets a reading of 415 mg/dl, What action does the nurse take next?

• Decrease TPN rate.
• Stop TPN.
• Contact health care provider.
• Administer insulin.

Explanation: Answer reason: Severe hyperglycemia is a common complication of TPN due to the high dextrose load, and a value of 415 mg/dL indicates a significant metabolic complication requiring prompt treatment adjustment. The nurse should anticipate an order to modify the TPN regimen and/or initiate or titrate an insulin protocol (e.g., sliding scale, IV insulin, or insulin added to the TPN) based on institutional policy and the patient’s overall status. Abruptly stopping or reducing the infusion independently can precipitate rebound hypoglycemia and disrupt nutrition therapy, and it is typically a provider-directed change. Giving insulin without an existing order is outside nursing scope in most settings, so notifying the provider (and following any standing hyperglycemia protocol if available) is the safest next step.

A nurse receives a client who has just returned from a circular skin punch biopsy to confirm a diagnosis of skin cancer. The nurse should immediately observe the site for?

• Dehiscence
• Infection
• Bleeding
• Swelling

Explanation: Answer reason: Immediate post-procedure nursing assessment prioritizes early detection of acute complications that can quickly threaten stability. A punch biopsy creates an open wound with potential disruption of small dermal vessels, making active oozing or hemorrhage the most time-sensitive issue to identify and control with pressure/dressing reinforcement. Infection is a later complication that typically develops hours to days after the procedure rather than immediately on return. Dehiscence is uncommon with a small circular biopsy and would usually be preceded by uncontrolled bleeding or poor wound integrity over time.

Lumbar puncture was performed on a client for a myelogram. After the procedure, he complains of severe headache. The most appropriate nursing intervention is?

• Increase the client’s oral fluid intake
• Administer the prescribed antihypertensives of this client
• Give patient roll lenses
• Place a cool pack over the lumbar puncture site

Explanation: Answer reason: Nursing care focuses on measures that help restore CSF volume/pressure and reduce symptoms, including encouraging fluids (and commonly caffeine if ordered) and maintaining prescribed positioning. Increasing oral fluid intake supports hydration and can help the body replenish CSF, making it the best option provided. Antihypertensives do not treat the underlying cause and may worsen perfusion if hypotension is present. Local cooling at the puncture site does not address the intracranial mechanism responsible for the headache.

A registered nurse is precepting a new graduate nurse on the orthopedic unit. Which action by the graduate nurse requires the registered nurse to intervene?

• Elevating a client's residual limb on a pillow 1 day after above-the-knee amputation
• Placing an abductor pillow between a client's legs after total hip replacement
• Positioning a client with Buck traction supine with the foot of the bed raised
• Using pillows to raise a client's extremity following cast placement

Explanation: Answer reason: Keeping an above-the-knee residual limb elevated on pillows encourages hip flexion and can quickly lead to a flexion contracture, which is difficult to reverse. Early care instead emphasizes maintaining neutral alignment and incorporating prone positioning as ordered/tolerated rather than prolonged pillow elevation. The other actions are standard orthopedic precautions/interventions that reduce complications (hip dislocation prevention, traction alignment, and edema control after casting).

The nurse is assessing the neurovascular status of a client who returned to the surgical nursing unit 4 hours ago after undergoing aortoiliac bypass graft. The affected leg is warm, and the nurse notes redness and edema. The pedal pulse is palpable and unchanged from admission. How should the nurse correctly interpret the client's neurovascular status?

• The neurovascular status is normal because of increased blood flow through the leg.
• The neurovascular status is moderately impaired, and the surgeon should be called.
• The neurovascular status is slightly deteriorating and should be monitored for another hour.
• The neurovascular status is adequate from an arterial approach, but venous complications are arising.

Explanation: Answer reason: Aortoiliac bypass aims to restore arterial perfusion, which is best reflected by a palpable, unchanged distal pedal pulse and a warm extremity. Redness and edema shortly after surgery more strongly suggest venous congestion/venous outflow compromise or postoperative dependent swelling rather than acute arterial occlusion. If arterial flow were failing, expected findings would include coolness, pallor, delayed capillary refill, and diminished/absent pulses. Because the arterial assessment remains reassuring while swelling and erythema are present, the most accurate interpretation is adequate arterial supply with emerging venous-related issues that warrant ongoing assessment and supportive management.

A client has been admitted to the hospital with a fractured pelvis sustained in a motor vehicle crash. The nurse monitors for complications and should assess the client closely for which finding in the early posttrauma period?

• Pain
• Fever
• Hematuria
• Bradycardia

Explanation: Answer reason: Blood in the urine is an early, specific clue of urinary tract damage and may precede signs of infection or later complications. Pain is expected with a fracture and is not a distinguishing complication signal. Fever typically develops later with infection, and bradycardia is not a typical early indicator of pelvic-fracture complications compared with hemorrhage/urogenital injury findings.

A child is admitted to the hospital after being seen in the emergency department with complaints of right lower quadrant abdominal pain, nausea and vomiting, fever, and chills. The physician suspects appendicitis. Which of the following assessment findings would the nurse immediately report to the physician?

• Sudden relief of pain
• Decreasing oral temperature
• Refusal to take fluids by mouth
• Increasing complaints of pain

Explanation: Answer reason: Perforation can quickly progress to peritonitis and sepsis, requiring urgent reassessment and possible emergent surgical management. Ongoing or worsening pain is expected with inflammation and is important to monitor, but it is less specific for rupture than sudden pain relief. A declining oral temperature or refusing oral fluids may occur with illness/NPO status and dehydration risk, but they are not as immediately alarming for acute deterioration as possible perforation.

The nurse is performing an assessment on a pregnant client in the last trimester with a diagnosis of severe preeclampsia. The nurse reviews the assessment findings and determines that which finding is most closely associated with a complication of this diagnosis?

• Enlargement of the breasts
• Complaints of feeling hot when the room is cool
• Periods of fetal movement followed by quiet periods
• Evidence of bleeding, such as in the gums, petechiae, and purpura

Explanation: Answer reason: Mucosal bleeding, petechiae, and purpura are classic clinical clues of low platelets and consumptive coagulopathy, which are life-threatening maternal complications requiring urgent escalation of care. The other findings reflect normal pregnancy or benign physiologic changes rather than end-organ dysfunction. Recognizing bleeding manifestations is critical because they signal high risk for hemorrhage (including placental abruption and postpartum hemorrhage) and imminent maternal deterioration.

A client who was admitted to the psychiatric unit in a manic state attacked another client. Seclusion has been ordered, and the nurse is assessing the client every 15 minutes. Which assessment should receive the highest priority?

• Level of psychomotor agitation
• Vital signs
• Nutritional intake
• Verbal and nonverbal behavior

Explanation: Answer reason: Frequent monitoring of circulation and cardiopulmonary status provides the earliest objective indicators of deterioration requiring immediate intervention or discontinuation/adjustment of seclusion. While ongoing observation of agitation and behavior is important for safety and determining readiness to end seclusion, it is secondary to detecting life-threatening physiologic instability. Nutritional intake is relevant over a longer time frame and does not supersede immediate assessment for acute complications.

On the day of surgery, a client with diabetes who takes insulin on a sliding scale is to have nothing by mouth and all medications withheld. The client’s 0600 glucose level is 300 mg/dL (16.7 mmol/L). What should the nurse do?

• Withhold all medications.
• Administer the insulin dose dictated by the sliding scale.
• Call the health care provider (HCP) for specific prescriptions based on the glucose level.
• Notify the surgery department.

Explanation: Answer reason: Marked hyperglycemia preoperatively increases risk for dehydration, electrolyte shifts, impaired wound healing, and infection, and it may warrant delaying surgery until better controlled. An NPO order with “all medications withheld” conflicts with the need for glycemic management, and a glucose of 300 mg/dL is beyond routine “give and go” nursing management when the perioperative plan is unclear. The safest action is to obtain provider-specific orders (e.g., correction insulin, IV fluids, additional monitoring, or anesthesia/surgery guidance) to prevent perioperative complications. Administering insulin purely by a routine sliding scale may be inappropriate without knowing the protocol for NPO status and the perioperative target range, while simply withholding meds leaves severe hyperglycemia untreated.

A client recovers from a laryngectomy and is mechanically ventilated. Which action does the nurse take when caring for the client?

• Determine the client’s position of comfort.
• Suction the tracheostomy every 30 minutes.
• Initiate the client’s clear liquid diet.
• Determine the tracheostomy minimal leak.

Explanation: Answer reason: In a mechanically ventilated patient with a tracheostomy, ensuring an adequate cuff seal with a minimal leak is essential to deliver the set tidal volume and prevent loss of ventilation. It also reduces aspiration risk by limiting leakage of secretions around the cuff. Routine suctioning on a fixed schedule is inappropriate because it increases mucosal trauma and hypoxemia risk; suction should be based on assessment (e.g., visible secretions, coarse breath sounds, rising peak pressures). Starting oral intake is unsafe immediately post-laryngectomy due to high aspiration risk and need to confirm swallowing safety and airway protection.

The nurse cares for an elderly man diagnosed with Alzheimer's disease. It is MOST important for the nurse to take which action?

• Leave the television on all day in the client's room.
• Frequently inform the client of the room and bathroom location.
• Provide the client with newspapers and magazines.
• Assign a staff member to check on the client every 15 minutes.

Explanation: Answer reason: Alzheimer’s disease commonly causes disorientation and impaired short-term memory, increasing the risk for wandering and falls. Frequent reorientation to essential locations supports safe ambulation and helps the client meet basic needs with less anxiety and confusion. This intervention addresses both safety and cognitive support in a direct, ongoing way. In contrast, leaving the television on all day can worsen agitation and overstimulation, and frequent checks alone do not correct disorientation or promote independent, safe navigation.

A nurse suspects that an air embolism has occurred when the client's central venous catheter disconnects from the intravenous (IV) tubing. The nurse immediately places the client in which position?

• Trendelenburg's on the left side
• Trendelenburg's on the right side
• Reverse Trendelenburg's on the left side
• Reverse Trendelenburg's on the right side

Explanation: Answer reason: Placing the client in left lateral decubitus with Trendelenburg (Durant maneuver) uses gravity to keep air in the apex of the right ventricle and away from the pulmonary outflow tract. This positioning also reduces the risk of hemodynamic collapse from obstruction of pulmonary blood flow. Reverse Trendelenburg would favor air migration toward the pulmonary artery and worsen the complication. Immediate positioning is a critical nursing action while further emergency measures are initiated.

A patient is newly diagnosed with cirrhosis of the liver. Which of the following statements indicates he understands his condition?

• I will be prescribed digoxin to help this condition.
• I know my condition will get better with time.
• I will only be able to drink a maximum of 3 times per week.
• I may need to receive a paracentesis if I experience fluid build up.

Explanation: Answer reason: Cirrhosis causes portal hypertension and low albumin, which commonly leads to ascites and abdominal fluid accumulation. Therapeutic paracentesis is an appropriate procedure to relieve significant ascites and respiratory discomfort and is a typical complication-management plan patients should understand. Digoxin is a cardiac medication and is not a standard treatment for cirrhosis itself. Cirrhosis is generally progressive/irreversible, and alcohol recommendations emphasize complete abstinence rather than limiting drinks to a few times per week.

The hemodialysis client with a left arm fistula is at risk for steal syndrome. The nurse assesses this client for which of the following clinical manifestations?

• Warmth, redness, and pain in the left hand.
• Pallor, diminished pulse, and pain in the left hand.
• Edema and reddish discoloration of the left arm
• Aching pain, pallor, and edema in the left arm.

Explanation: Answer reason: Steal syndrome occurs when an AV fistula diverts arterial blood away from the distal extremity, producing distal ischemia. Ischemia is assessed by coolness/pallor, reduced or absent distal pulses, and pain (often worse during dialysis or with hand use) in the hand beyond the fistula. Findings like warmth and redness suggest infection or inflammation rather than decreased perfusion. Arm edema and reddish discoloration more strongly point to venous outflow obstruction or thrombosis rather than arterial “steal.”.

The nurse is caring for a client with benign prostatic hyperplasia (BPH) who had an indwelling urethral catheter removed 6 hours ago. Which of the following findings by the nurse would be a priority to follow up?

• Palpable bladder with a urine output of 100 mL
• Oral fluid intake is more than urine output
• Elevated blood urea nitrogen (BUN)
• Burning upon urination

Explanation: Answer reason: A distended/palpable bladder combined with minimal output several hours after removal strongly suggests obstruction/retention, which is a time-sensitive complication in a client with BPH. This finding warrants immediate assessment (e.g., bladder scan) and prompt intervention per protocol to prevent worsening retention. In contrast, transient burning can be expected after catheter removal, and isolated BUN elevation or intake exceeding output is less immediately diagnostic of acute obstruction in this moment.

A client scheduled for pneumonectomy tells the nurse that a friend of his had lung surgery and had chest tubes. The client asks the nurse about how long his chest tubes will be in place after surgery. The nurse responds that?

• They will be removed after 3 to 4 days.
• They will be in place for 24 to 48 hours.
• They usually remain in place for a full week after surgery.
• Most likely, there will be no chest tubes in place after surgery.

Explanation: Answer reason: After a pneumonectomy, the operative hemithorax is intentionally left without a lung, so placing a standard chest tube to continuous suction can create excessive negative pressure and shift mediastinal structures, impairing hemodynamics and ventilation. Postoperative management typically aims to allow the space to fill gradually with fluid and for the mediastinum to stabilize. If any drainage device is used, it is generally temporary and specifically managed (e.g., clamped or without suction) rather than routine ongoing chest-tube therapy. Therefore the safest, most accurate expectation for patient teaching is that routine chest tubes are usually not present after pneumonectomy, unlike many other lung resections.

A client undergoes a thyroidectomy and the nurse monitors the client for signs of damage to the parathyroid glands postoperatively. Which of the following findings would indicate damage to the parathyroid glands?

• Neck pain
• Hoarseness
• Respiratory distress
• Tingling around the mouth

Explanation: Answer reason: Early hypocalcemia commonly presents with perioral tingling/numbness and can progress to tetany (e.g., carpopedal spasm, positive Trousseau/Chvostek) and laryngospasm. This finding is therefore a key postoperative complication cue that specifically points to parathyroid dysfunction rather than expected incision discomfort. Hoarseness more strongly suggests recurrent laryngeal nerve irritation, and generalized respiratory distress is less specific without accompanying hypocalcemic neuromuscular signs.

After a frontal craniotomy, a patient returns to the neurosurgery unit. Which of the following orders should the nurse question?

• Give dexamethasone (Decadron), 4mg every six hours
• Provide oxygen at 2 LPM
• Elevate the head of bed at 30 degrees
• Infuse IVF at 160 ml/hr

Explanation: Answer reason: A rate of 160 mL/hr is relatively high for routine maintenance and should prompt clarification about the indication, fluid type, and targeted intake/output goals. Typical postoperative neuro care often uses controlled or restricted fluids with close monitoring of urine output, serum sodium/osmolality, and neurologic status. By contrast, head-of-bed elevation and low-flow oxygen support cerebral venous drainage and oxygenation, and corticosteroids may be ordered to reduce vasogenic edema depending on the pathology.

The nurse is initiating continuous bladder irrigation on a patient that just underwent a prostatectomy. The nurse understands that the flow rate is adequate if?

• The patient's urine is pale yellow or pale pink tinged
• No urine output is noted
• The patient's urine is clear as water
• Output equals input

Explanation: Answer reason: An adequate rate produces effluent that is light pink to pale yellow, indicating small expected postoperative oozing without significant active hemorrhage. If the urine becomes bright red or contains increasing clots, the rate is too low or bleeding is increasing; if it is completely clear, the rate may be higher than needed. “Output equals input” is incorrect because true urine output must be calculated by subtracting irrigant infused from total drainage.

The nurse is caring for a client with the syndrome of inappropriate antidiuretic hormone (SIADH). Which assessment finding requires immediate follow-up?

• Disorientation
• High urine specific gravity
• Oliguria
• Increased thirst

Explanation: Answer reason: Acute or worsening neurologic changes signal cerebral edema and impending seizures, making this a time-sensitive complication that requires prompt evaluation and intervention. High urine specific gravity and oliguria are expected effects of ADH-mediated water reabsorption and are not, by themselves, the most urgent red flags. Increased thirst is less typical as a priority finding in SIADH and is not as immediately dangerous as altered mental status.

The nurse is planning care for a child being admitted with Kawasaki disease and should give priority to which nursing intervention?

• Apply cool compresses to the skin of the hands and feet
• Monitor for a gallop heart rhythm and decreased urine output
• Prepare a quiet, non-stimulating, and restful environment
• Provide soft foods and liberal amounts of clear liquids

Explanation: Answer reason: A gallop rhythm can indicate decreased ventricular function, and reduced urine output is an early sign of poor perfusion and evolving shock/heart failure. This option focuses on monitoring for life-threatening complications that require prompt escalation of care and treatment adjustments. Comfort measures, environmental rest, and diet/hydration support symptoms but do not supersede surveillance for cardiac deterioration.

A nursing intervention in thrombophlebitis would be contraindicated?

• Maintaining strict bedrest
• Turning the patient from side to side
• Applying warm packs to the affected leg
• Massaging the affected leg

Explanation: Answer reason: Manipulating the limb can mechanically disturb the thrombus and increase the chance of a potentially fatal pulmonary embolus. Supportive measures such as heat can help reduce pain and promote local circulation without physically disrupting the clot. Bedrest and gentle repositioning are commonly used to limit venous stasis and prevent additional complications while anticoagulation and other therapies take effect.

A client diagnosed with a sub-arachnoid hemorrhage has undergone a craniotomy for repair of a ruptured aneurysm. Which intervention will the intensive care nurse implement?

• Administer a stool softener BID
• Encourage the client to cough hourly
• Monitor neurological status every shift
• Maintain the dopamine drip to keep BP at 160/90

Explanation: Answer reason: A stool softener reduces constipation and minimizes bearing down during defecation, directly lowering this risk. Hourly coughing can transiently increase ICP and is not routinely promoted aggressively in this context unless clearly indicated for airway clearance. Neurologic checks should be more frequent than once per shift in an ICU after craniotomy, and targeting hypertension with dopamine is inappropriate because dopamine typically raises blood pressure and may worsen bleeding risk.

The nurse cares for a client who returns from the operating room after a tracheostomy tube placement procedure. Which of the following is the nurse's priority when caring for a client with a new tracheostomy?

• Changing the inner cannula within the first 8 hours to help prevent mucus plugs
• Checking the tightness of ties and adjusting if necessary, allowing 1 finger to fit under these ties
• Deflating and re-inflating the cuff every 4 hours to prevent mucosal tissue damage
• Performing frequent mouth care every 2 hours to help prevent infection

Explanation: Answer reason: Securing the tube with appropriately snug ties reduces this immediate, high-consequence complication while avoiding excessive pressure that can impair skin integrity and venous return. Early inner cannula changes and oral care are important but are secondary to maintaining a patent, secure airway device. Routine cuff deflation/reinflation is not a priority nursing action immediately post-op and can destabilize ventilation/aspiration protection if done without a specific indication and monitoring.

A client has a chest-drainage tube after a thoracotomy was performed. The nurse should report which assessment finding to the surgeon immediately?

• 280 mL of fluid drained in the first postoperative hour
• Chest drainage that is grossly bloody immediately after surgery
• Rise and fall of fluid in the water seal compartment with inspiration and expiration
• Scant bloody drainage on postoperative day 1, followed by increased bloody drainage

Explanation: Answer reason: Increasing bloody output after initially scant drainage can indicate postoperative hemorrhage, disruption of a vessel, or loss of hemostasis and warrants urgent surgeon notification. By contrast, tidaling in the water-seal chamber reflects expected pleural pressure changes and is a normal finding when the system is patent. Immediate postoperative drainage can be sanguineous, and a single-hour volume must be interpreted with trends and hemodynamics; the pattern of rising bleeding is the more concerning signal for acute deterioration.

The nurse caring for a client diagnosed with an inoperable lung tumor creates a plan of care addressing complications related to the disorder. The nurse includes in the plan to monitor for the early signs/symptoms of vena cava syndrome. Which is an early sign/symptom of this oncological emergency?

• Hand and arm edema
• Signs of disorientation
• Edema of the face and eyes
• Bluish skin discoloration around the mouth

Explanation: Answer reason: Early findings reflect venous congestion above the obstruction, classically facial/periorbital swelling and a feeling of head fullness that may be worse when bending forward or lying down. Upper-extremity edema can occur but facial/periorbital edema is a hallmark early cue nurses monitor for to detect progression quickly. Disorientation suggests later cerebral edema/hypoxia, and perioral cyanosis indicates more advanced respiratory compromise rather than an early sign of SVC obstruction.

The nurse prepares to administer a continuous intravenous (IV) infusion through a peripheral IV to a client who has dehydration. Which is the priority nursing assessment before initiating the IV infusion?

• Asking the client about the dominant side
• Checking a daily body weight
• Checking the serum electrolytes
• Checking intake and output records

Explanation: Answer reason: Recent urine output and overall fluid balance provide the most immediate, actionable baseline for titrating a continuous infusion and identifying risk for complications (e.g., oliguria suggesting poor kidney perfusion). Daily weight is useful for trending but is less immediate for pre-infusion decision-making than fluid balance data. Serum electrolytes are important but may not be available immediately and do not directly indicate current circulating volume or urine production needed to guide starting fluids safely.

While assessing a thoracotomy incisional area from which a chest tube exits, the nurse feels a crackling sensation under the fingertips along the entire incision. What should the nurse do next?

• Lower the head of the bed, and call the healthcare provider (HCP).
• Prepare an aspiration tray.
• Mark the area with a skin pencil at the outer periphery of the crackling.
• Turn off the suction of the chest drainage system.

Explanation: Answer reason: Crackling under the skin after thoracotomy with a chest tube is consistent with subcutaneous emphysema from air leaking into subcutaneous tissue. The immediate nursing priority is to assess and trend the extent by outlining the margins so progression or resolution can be evaluated objectively and communicated. This supports early recognition of worsening air leak or inadequate chest tube function while allowing targeted follow-up assessment. Calling the provider may be needed if it rapidly progresses or causes respiratory compromise, but the next action is to quantify and document the finding first.

When preparing a client for discharge 2 days after an abdominal hysterectomy, the nurse should instruct the client to avoid which activity until recovery is complete?

• Swimming in a pool treated with chlorine for 6 weeks after surgery
• Walking at a leisurely pace for 30 minutes at least once a day
• Driving until the client can push the brake pedal without pain
• Lifting >2 lb (0.9 kg) until the abdominal incision has healed

Explanation: Answer reason: Submerging in water (pool, bath, hot tub) increases exposure to microorganisms and moisture, which can promote wound or vaginal-cuff infection and delay healing, so it should be avoided until cleared—commonly around 6 weeks. Early ambulation is encouraged to reduce thromboembolic risk and support bowel function. Driving is typically allowed when the patient can safely perform an emergency stop and is not impaired by pain or sedating analgesics. Lifting restrictions are appropriate, but an absolute limit of >2 lb is unusually strict and less representative of standard discharge guidance than the clear “no submersion” precaution.

The nurse is caring for a client diagnosed with acute pericarditis. Which complication is the client at risk for developing?

• Cardiac tamponade
• Hemothorax
• Pulmonary embolism
• Tension pneumothorax

Explanation: Answer reason: Acute pericarditis can lead to inflammatory pericardial effusion, and rapid fluid accumulation in the pericardial sac can compress the heart and impair ventricular filling. This reduces stroke volume and cardiac output and can quickly progress to obstructive shock, making it the key life-threatening complication to monitor for. The other options are primarily pleural/lung (hemothorax, tension pneumothorax) or thromboembolic (pulmonary embolism) processes and are not the characteristic direct complication of pericardial inflammation. Clinically, new hypotension, muffled heart sounds, rising JVP, or pulsus paradoxus would heighten concern for this complication and warrant urgent intervention.

A client with schizophrenia has been taking Thorazine (chlorpromazine) 200mg four times a day. Which finding should be reported to the doctor immediately?

• The client complains of thirst.
• The client has gained four pounds in the past two months.
• The client complains of a sore throat.
• The client naps throughout the day.

Explanation: Answer reason: Antipsychotics can rarely cause blood dyscrasias such as agranulocytosis, and early infection signs may be subtle. A sore throat can indicate developing neutropenia with high risk for rapid progression to serious infection, so it warrants immediate provider notification and prompt CBC evaluation. The other findings are more consistent with common, less urgent effects of chlorpromazine such as anticholinergic symptoms (thirst/dry mouth), mild weight gain, and sedation. Immediate reporting is prioritized when a symptom suggests a potentially life-threatening adverse drug reaction rather than expected, manageable side effects.

The nurse is preparing to administer medications to a client with an asthma exacerbation. Which prescription should the nurse confirm with the health care provider prior to administration? Click on the exhibit button for additional information.?

• Albuterol 2.5 mg per nebulizer every 4 hours
• Enoxaparin 40 mg subcutaneously every 24 hours
• Methylprednisolone succinate 20 mg IV every 6 hours
• Potassium chloride 20 mEq IV every 24 hours

Explanation: Answer reason: In an asthma exacerbation, bronchodilators and systemic corticosteroids are expected therapies, while prophylactic anticoagulation may be inappropriate if the exhibit indicates low platelets or another bleeding concern. This order should be clarified to prevent serious hemorrhage or worsening thrombocytopenia. By contrast, short-acting beta-agonists and IV steroids directly address airway inflammation/bronchospasm and are commonly indicated in this setting.

The client who has been prescribed phenytoin for epilepsy calls the clinic and reports a measles-like rash. Which intervention should the nurse implement?

• Instruct the client to come to the clinic immediately.
• Determine if the client is drinking grapefruit juice.
• Encourage the client to apply a hydrocortisone cream to the rash.
• Explain that this is a common side effect of this medication.

Explanation: Answer reason: A new rash in a patient taking an anticonvulsant can indicate a potentially serious hypersensitivity reaction that requires prompt clinical evaluation and possible discontinuation. Phenytoin can cause severe cutaneous adverse reactions (including SJS/TEN), and a “measles-like” rash should not be managed with reassurance or topical self-treatment. Immediate assessment allows the provider to evaluate severity, mucosal involvement, systemic symptoms, and determine whether urgent escalation is needed. Asking about grapefruit juice is not the priority because the immediate safety concern is a possible dangerous drug reaction.

Mr. Gaugin’s blood pressure has returned to normal and he is to be discharged with a prescription for an oral antihypertensive medication. The nurse is preparing a client education guide for Mr. Gaugin. Which of the following information should be included in Mr.Gaugin’s education Guide?

• Drink high caloric fluids
• Change positions slowly.
• Take over-the-counter appetite suppressants.
• Exercise should consist of walking daily (as tolerated).

Explanation: Answer reason: Antihypertensive medications commonly cause orthostatic hypotension due to reduced vascular tone and/or volume, increasing fall risk when standing quickly. Teaching the client to rise slowly from lying to sitting and then standing helps prevent dizziness, syncope, and injury during the initiation and continuation of therapy. This instruction is broadly applicable across many antihypertensive classes and is a key discharge safety point. In contrast, recommending OTC appetite suppressants is unsafe because many contain stimulants that can raise blood pressure and counteract therapy.

An elderly client with a history of stable chronic obstructive pulmonary disease, alcohol abuse, and cirrhosis has a serum theophylline level of 25.8 mcg/mL (143 µmol/L). Which clinical manifestation associated with theophylline toxicity should worry the nurse most?

• Alterations in color vision
• Gum (gingival) hypertrophy
• Hyperthermia
• Seizure activity

Explanation: Answer reason: With impaired hepatic metabolism (cirrhosis, alcohol use), drug clearance falls and toxic levels are more likely, making severe neurologic effects a priority concern. Seizures are a critical manifestation because they can rapidly lead to hypoxia, aspiration, dysrhythmias, and cardiovascular collapse, requiring immediate emergency management. By contrast, visual color changes and gingival overgrowth are classically associated with other medications, and fever is less specific and typically less immediately life-threatening than convulsions in this context.

A teenage client receives a prescription for erythromycin for the treatment of pelvic inflammatory disease. Which medication instruction does the nurse provide to the client?

• "Take the medication with fruit juice to increase absorption."
• "Take the medication with antacids if you experience stomach upset."
• "Notify the health care provider if you notice a change in your hearing."
• "Use a stool softener to prevent the side effect of constipation."

Explanation: Answer reason: " Macrolide antibiotics can rarely cause ototoxicity, especially with higher doses or prolonged therapy, and early recognition helps prevent potentially persistent auditory damage. New tinnitus, decreased hearing, or vertigo should be reported promptly so the prescriber can evaluate the need to stop or change therapy. Antacids can interfere with absorption of some erythromycin formulations and are not an appropriate routine self-management instruction. Constipation is not a typical prominent adverse effect; gastrointestinal upset/diarrhea is more common.

A client is being discharged on Coumadin after hospitalization for atrial fibrillation. The nurse recognizes that which of the following foods would be restricted while the client is on this medication?

• Potatoes
• Cabbage
• Macaroni
• Apples

Explanation: Answer reason: Leafy green and cruciferous vegetables are common high–vitamin K foods that can lower the INR and increase thromboembolic risk if intake rises or fluctuates. This choice best matches a food that is typically high in vitamin K compared with the other options listed. The key teaching is not necessarily total avoidance, but keeping vitamin K intake consistent and monitoring INR when diet changes.

The nurse provides discharge teaching for the parent of a child newly prescribed methylphenidate for attention-deficit hyperactivity disorder (ADHD). The nurse advises the parent that the child might experience which side effects?

• Decreased blood pressure and growth delays
• Heart palpitations and weight gain
• Loss of appetite and restlessness
• Trouble sleeping and a dry cough

Explanation: Answer reason: Methylphenidate can lead to decreased appetite with possible weight loss and can also cause nervousness, irritability, and restlessness. It more typically increases heart rate and blood pressure rather than lowering blood pressure, making that distractor inconsistent. Insomnia is a known effect, but a dry cough is not a characteristic adverse effect of this medication and makes that option less correct overall.

A post-adrenalectomy client is admitted to the ICU and is on IV hydrocortisone. Which nursing intervention should be included in the client’s plan of care?

• Monitor blood glucose levels frequently.
• Keep the client flat on back for 24 hours.
• Discontinue hydrocortisone once vital signs become stable
• Educate the client on how to properly clean his wound at home.

Explanation: Answer reason: Systemic corticosteroids can cause significant hyperglycemia by increasing gluconeogenesis and inducing insulin resistance, and this risk is heightened in critically ill postoperative patients. After adrenalectomy, hydrocortisone is often given as stress-dose replacement, so close monitoring helps detect and treat steroid-related glucose excursions promptly to prevent complications such as osmotic diuresis, dehydration, and infection risk. Lying flat for 24 hours is not a standard requirement after adrenal surgery and may increase pulmonary complications. Steroids should not be stopped abruptly when stability is achieved because tapering is often needed to avoid adrenal insufficiency/crisis, and wound-care teaching is not the ICU priority compared with immediate medication effects monitoring.

The nurse has just completed discharge teaching for a client who had aortic valve replacement with a mechanical heart valve. Which statement by the client indicates that teaching has been effective?

• "I'm glad that I can continue taking my Ginkgo biloba."
• "I will increase my intake of leafy green vegetables."
• "I will start applying vitamin E to my chest incision after showering."
• "I will shave with an electric razor from now on."

Explanation: Answer reason: " Clients with mechanical heart valves require lifelong anticoagulation, and key discharge teaching focuses on minimizing bleeding risk from everyday activities. Using an electric razor reduces the chance of cuts and prolonged bleeding compared with a blade. In contrast, Ginkgo biloba can increase bleeding risk when combined with anticoagulants, and increasing leafy greens can destabilize INR due to vitamin K content. Applying products like vitamin E to an incision is not the priority teaching point and may irritate the wound or interfere with healing guidance.

A client with schizophrenia is receiving haloperidol 2 mg orally three times a day. The client approaches the nurse's station presenting with eyes rolled upward towards the head. The nurse recognizes this finding as what type of side effect?

• Nystagmus
• Tardive dyskinesia
• Oculogyric crisis
• Dysphagia

Explanation: Answer reason: Forced upward deviation of the eyes is characteristic of an oculogyric crisis, which can be distressing and may also involve neck or jaw muscle spasm. This is treated promptly with an anticholinergic (e.g., benztropine) or antihistamine (e.g., diphenhydramine) to reverse the dystonia. Tardive dyskinesia is a delayed-onset syndrome featuring choreoathetoid, repetitive movements (often orofacial) rather than an abrupt eye-rolling episode. Recognizing this pattern is important because it signals an urgent medication adverse effect requiring immediate intervention.

A 14-year-old is admitted to the medical ward for status asthmaticus. He has put on IV theophylline. Which manifestation would the nurse consider as a side effect of the drug?

• Grand mal seizures
• Palpitations
• Sleeplessness
• Headache

Explanation: Answer reason: Theophylline is a methylxanthine that stimulates the CNS and heart and can increase catecholamine effects, producing tachycardia and dysrhythmia symptoms. An awareness of cardiac stimulation is important in IV administration because toxicity can develop with relatively small increases in serum level. Seizures are more consistent with severe toxicity rather than an expected side effect at therapeutic doses. Headache and sleeplessness can occur, but cardiac symptoms are a key clinically concerning adverse effect nurses monitor closely.

A nurse at the Emergency Department attends to a 9-year-old male patient, accompanied by mother, with chief complaints of fatigue. History reveals that the child has a congenital heart defect and has been on the chronic use of digoxin. Which finding would cause the nurse to suspect digoxin toxicity?

• Bradycardia
• Confusion
• Weight loss
• Dyspnea

Explanation: Answer reason: Digoxin increases vagal tone and slows conduction through the AV node, so toxicity commonly presents with clinically significant bradycardia and other dysrhythmias. In a child on chronic digoxin therapy who presents with fatigue, an abnormally slow pulse is a high-yield red flag that should prompt immediate assessment of heart rate/rhythm and consideration of serum digoxin and electrolyte (especially potassium) evaluation. Confusion can occur with toxicity but is less specific and less immediately predictive than a conduction-related change. Dyspnea and weight loss are more consistent with underlying cardiac disease or other chronic conditions rather than a classic toxic effect.

Hydrochlorothiazide (HydroDiuril) has been prescribed for a client. The nurse contacts the physician to verify the prescription if which of the following conditions is noted in the assessment data?

• Nephrotic syndrome
• Allergy to eggs
• Allergy to sulfonamides
• Hypertension

Explanation: Answer reason: Verifying with the prescriber helps determine reaction severity, alternative diuretics, and monitoring needs if use is still considered. Hypertension is a common indication for this medication, not a reason to question it. An egg allergy is unrelated to this drug’s structure and typical contraindications.

Soon after admission of a primigravid client at 38 weeks’ gestation with severe preeclampsia, the primary healthcare provider (HCP) prescribes a continuous intravenous infusion of 5% dextrose in Ringer’s solution and 4 g of magnesium sulfate. While the medication is being administered, which assessment finding should the nurse report immediately?

• Respiratory rate of 12 breaths/min
• Patellar reflex of +2
• Blood pressure of 160/88 mm Hg
• Urinary output exceeding intake

Explanation: Answer reason: A respiratory rate at the low end of normal in a patient receiving magnesium warrants immediate evaluation, holding the infusion, and readiness to administer calcium gluconate if worsening occurs. A +2 patellar reflex is normal (loss of deep tendon reflexes is more concerning for toxicity). Severe-range blood pressure is expected in severe preeclampsia but is not a new infusion-related toxicity indicator, and urine output exceeding intake is not consistent with magnesium accumulation risk (decreased output would increase toxicity risk).

The nurse cares for a client receiving quinidine. It is MOST important for the nurse to include which information in the client's teaching plan?

• Call your health care provider if you have ringing in your ears.
• Eat foods high in vitamin C.
• Your urine may turn dark amber in color.
• Check your pulse before you take the medication.

Explanation: Answer reason: Quinidine can cause cinchonism, a toxicity syndrome characterized by tinnitus, hearing changes, headache, and visual disturbances, and it may precede more serious complications. Teaching the client to promptly report tinnitus supports early recognition and discontinuation/adjustment before dysrhythmias or other toxicity worsens. Checking the pulse is more classically emphasized for drugs like digoxin or some beta-blockers and is not the key safety teaching for this medication. Dietary vitamin C and dark amber urine are not priority, clinically specific safety points for quinidine therapy.

A patient with UTI on treatment, after administration of Nitrofurentoin (furadentin) the patient was complain of dark colour urine , the nurse what to do ....?

• Irradigate the catheter
• Take urine sample
• Document this finding
• Inform the health care provider

Explanation: Answer reason: The appropriate nursing action is to recognize it as a normal adverse effect, provide reassurance/teaching as needed, and record it in the chart. Notifying the provider or obtaining a urine sample is unnecessary unless other concerning symptoms occur (e.g., jaundice, dyspnea, flank pain, hematuria). Catheter irrigation is unrelated and could introduce infection or cause trauma if not indicated.

A client with acne has been using isotretinoin. She tells the nurse that she recently learned she is pregnant. She asks "Will my pregnancy interfere with the medication's effectiveness?" Which of the following is the appropriate response by the nurse?

• "The medication is contraindicated for pregnant women."
• "You will have to change the route of administration, because you are pregnant."
• "There is no reason you can't continue taking it."
• "If the medication helps you look better, that will help feel better about yourself."

Explanation: Answer reason: " Isotretinoin is a known potent teratogen, so pregnancy is an absolute contraindication due to high risk of severe fetal malformations. The safest, most clinically appropriate nursing response is to address the urgent safety issue rather than the client’s concern about efficacy. Suggesting route changes implies it could be continued safely, which is incorrect and unsafe. Reassuring continuation or focusing on self-esteem fails to recognize and respond to the immediate medication-related fetal risk and the need to stop the drug and notify the prescriber promptly.

A client is prescribed ciprofloxacin as treatment for a urinary tract infection. About which potential adverse effect does the nurse instruct this client?

• Polyuria
• Hypotension
• Cough
• Tendonitis

Explanation: Answer reason: Client education should emphasize reporting new tendon pain, swelling, or difficulty moving (often Achilles), and stopping the drug while seeking evaluation if these occur. This risk is clinically important because tendon rupture can cause significant morbidity and may occur even early in therapy, especially in older adults or those on corticosteroids. The other options are not characteristic teaching priorities for ciprofloxacin compared with tendon-related toxicity.

The nurse prepares to administer a prescribed dose of sodium polystyrene sulfonate to a client with hyperkalemia. Which action by the nurse is most important prior to administering the dose?

• Assessing the client's abdomen and reviewing the medical record for frequency of stools
• Assisting the client onto a bedside commode
• Teaching the client the importance of frequent assessment of potassium and sodium levels
• Verifying that the client had a daily weight assessment

Explanation: Answer reason: Baseline assessment of abdominal status and recent stool pattern screens for constipation, ileus, or obstruction—conditions that raise the risk of serious GI adverse effects (e.g., fecal impaction/ischemic bowel) and reduce effectiveness. Ensuring the client can pass stool also supports evaluation of treatment response after administration. Helping to a commode, teaching, or checking daily weights may be helpful, but they do not address the key immediate safety contraindication before giving this medication.

A licensed practical nurse (LPN) is reviewing the medication list of the client with a history of glaucoma. The LPN should consult with the registered nurse if which medication is prescribed for the client?

• Pilocarpine
• Carteolol hydrochloride
• Atropine sulfate (Isopto Atropine)
• Pilocarpine hydrochloride (Isopto Carpine)

Explanation: Answer reason: This makes the medication a key contraindication/precaution that warrants escalation to the RN for clarification and safety screening. In contrast, pilocarpine is a miotic that increases trabecular outflow and is used to lower intraocular pressure, and topical beta-blockers such as carteolol also reduce aqueous production. Consulting the RN helps prevent precipitating acute glaucoma worsening and potential vision loss.

The nurse is assigned to care for a client with cytomegalovirus retinitis and acquired immunodeficiency syndrome who is receiving foscarnet (Foscavir), an antiviral. The nurse checks the latest results of which of the following laboratory studies while the client is taking this medication?

• CD4 cell count
• Serum albumin level
• Serum creatinine level
• Lymphocyte count

Explanation: Answer reason: Serum creatinine is a direct, routinely used marker of kidney function and is expected to rise with drug-induced renal injury. Clients with AIDS/CMV may already have comorbid risks for renal impairment, increasing the need for close monitoring during therapy. CD4 and lymphocyte counts reflect immune status and disease progression but do not monitor for this medication’s most clinically important toxicity. Albumin is a nutrition/protein status marker and is not the priority safety lab for this drug.

The nurse is caring for a client who is receiving tacrolimus daily. Which finding indicates to the nurse that the client is experiencing an adverse effect of the medication?

• Hypotension
• Photophobia
• Profuse sweating
• Decrease in urine output

Explanation: Answer reason: A decreased urine output is a clinically important warning sign that requires prompt assessment of renal function (BUN/creatinine), tacrolimus level, and hydration/hemodynamics. The other findings listed are not characteristic hallmark adverse effects to monitor for this medication compared with renal impairment. Recognizing oliguria early helps prevent progression to acute kidney injury and guides timely provider notification and dose adjustment.

A nurse cares for a newborn in the neonatal intensive care unit (NICU). The client weighs 2.9 kg and has experienced a seizure. The nurse administers phenobarbital 43.5 mg IV as prescribed. Which assessment is most important for this newborn?

• Respiratory
• Musculoskeletal
• Cardiovascular
• Integumentary

Explanation: Answer reason: Newborns are particularly vulnerable to hypoventilation and apnea, especially when sedating anticonvulsants are given or seizures have recently occurred. Monitoring respiratory rate, effort, oxygen saturation, and signs of apnea directly addresses airway and breathing (ABCs) and guides immediate supportive actions. Cardiovascular effects can occur, but respiratory depression is the most critical and common acute adverse effect requiring rapid intervention.

Which medication should be avoided by the client with acute pancreatitis?

• Demerol (meperidine)
• Pepcid (famotidine)
• Zantac (ranitidine)
• Duramorph (morphine sulfate)

Explanation: Answer reason: Therefore, a nursing safety consideration is to avoid morphine in this setting when alternatives are available. Meperidine has historically been preferred for pancreatitis pain because it was thought to cause less sphincter of Oddi spasm (even though modern practice often favors other opioids for safety/efficacy reasons). H2 blockers like famotidine or ranitidine do not worsen pancreatitis via this mechanism and are not the key medication to avoid here.

A client with tuberculosis has a prescription for Myambutol (ethambutol HCl). The nurse should tell the client to notify the doctor immediately if he notices?

• Gastric distress
• Changes in hearing
• Red discoloration of bodily fluids
• Changes in color vision

Explanation: Answer reason: This adverse effect is clinically urgent because it can become irreversible if the drug is not stopped promptly. The other options are more consistent with toxicities of different TB drugs (e.g., ototoxicity with aminoglycosides, red-orange secretions with rifampin) or are less specific/less emergent. Prompt reporting allows immediate evaluation and medication adjustment to prevent permanent visual damage.

A nurse is assessing a client who is taking pregabalin to treat neuropathy pain. The nurse should document which of the following findings as an adverse effect of the medication?

• Somnolence
• Dilated pupils
• Excessive salivation
• Weight loss

Explanation: Answer reason: New or worsening drowsiness is a typical adverse effect that the nurse should recognize and document because it increases fall risk and may require dose adjustment. Dilated pupils and excessive salivation are not characteristic adverse effects for pregabalin and suggest other drug classes/toxicities. Weight change with pregabalin is more often weight gain related to increased appetite and fluid retention rather than weight loss.

The nurse is assigned to care for a client diagnosed with acquired immunodeficiency syndrome (AIDS) who is receiving amphotericin B for a fungal respiratory infection. Which would indicate an adverse effect of the medication?

• Hypokalemia
• Hyperkalemia
• Hypocalcemia
• Hypercalcemia

Explanation: Answer reason: This renal loss manifests as low serum potassium, which is a classic, testable adverse effect requiring monitoring and replacement as needed. In contrast, elevated potassium is not the expected pattern with this drug’s tubular wasting effect. Recognizing this adverse effect is important because hypokalemia increases risk for dysrhythmias and neuromuscular symptoms, particularly in medically fragile clients.

A client with severe acne is seen in the clinic and the primary health care provider (PHCP) prescribes isotretinoin. The nurse reviews the client's medication record and would contact the PHCP if the client is also taking which medication?

• Digoxin
• Phenytoin
• Vitamin A
• Furosemide

Explanation: Answer reason: This increases risk of hypervitaminosis A manifestations such as severe headache/intracranial hypertension, dry skin and mucous membranes, hepatotoxicity, and other systemic adverse effects. The nurse should flag this interaction as a contraindicated/unsafe combination requiring prescriber notification. The other listed drugs do not represent a classic high-risk interaction that would routinely require holding isotretinoin based solely on concomitant use.

A client with deep vein thrombosis has been receiving warfarin for 2 months. The client is to go to an anticoagulant monitoring laboratory every 3 weeks. The last visit to the laboratory was 2 weeks ago. The client reports bleeding gums, increased bruising, and dark stools. What should the nurse instruct the client to do?

• Decrease the dose of the warfarin.
• Return to laboratory for analysis of prothrombin times.
• Decrease the amount of vitamin K in the diet.
• Notify the healthcare provider (HCP) about the bleeding.

Explanation: Answer reason: These findings suggest excessive anticoagulation and possible gastrointestinal bleeding, which is a potentially serious adverse effect requiring prompt medical evaluation. Nursing teaching should prioritize safety by directing the client to seek provider guidance for urgent assessment, INR/PT testing, and possible dose adjustment or reversal rather than making independent medication changes. Dark stools can indicate melena and ongoing blood loss, increasing risk for hemodynamic instability and anemia. Advising self-adjustment of dose or diet is unsafe because it can worsen bleeding or destabilize anticoagulation control.

A client has been prescribed a nitroglycerin infusion. Which medication does the nurse ensure is available related to common side effects of nitroglycerin?

• Epinephrine
• Acetaminophen
• Diphenhydramine
• Morphine

Explanation: Answer reason: An analgesic like acetaminophen is appropriate to manage the headache while the infusion continues, supporting comfort without significantly worsening hypotension. Epinephrine and diphenhydramine are more consistent with treating anaphylaxis, which is not a typical nitroglycerin reaction. Morphine may be used for chest pain in acute coronary syndromes, but it does not specifically address the most common nitroglycerin side effect and can add risks such as hypotension and respiratory depression.

Your pregnant client has been hospitalized with hyperemesis gravidium. She is given ondansetron to treat this illness. What serious side effect should the hospital nurses be watching for?

• Continued nausea and vomiting
• Prolonged QT Interval
• Respiratory Distress
• Constipation

Explanation: Answer reason: Ondansetron can delay cardiac repolarization and increase the QT interval, which can precipitate torsades de pointes and sudden dysrhythmias. This risk is clinically important in hospitalized patients, especially if dehydration and electrolyte losses from hyperemesis (hypokalemia/hypomagnesemia) are present. Nursing monitoring should therefore include ECG/QT assessment and correction of electrolytes and avoidance of other QT-prolonging drugs. Constipation is common but not the key serious toxicity; persistent nausea/vomiting indicates lack of efficacy rather than a dangerous adverse effect.

The nurse is performing medication reconciliation to a patient in the Respiratory clinic recently prescribed with terbutaline. Which medication shall the nurse be concerned about?

• Atenolol
• Furosemide
• Cefuroxime
• Omeprazole

Explanation: Answer reason: Beta-agonists like terbutaline stimulate beta-2 receptors to cause bronchodilation, so concurrent beta-blocker therapy can blunt the therapeutic effect and potentially worsen bronchospasm. Atenolol is a beta-blocker (beta-1 selective but not completely), and selectivity can be lost at higher doses or in sensitive patients with reactive airway disease. This interaction is clinically important in a respiratory clinic setting because it can reduce symptom relief and increase risk of breathing difficulty. The other listed drugs do not directly antagonize beta-2 bronchodilation in the same way and are less concerning as primary interactions with terbutaline.

A client scheduled to undergo subtotal thyroidectomy is taking a potassium iodide solution. The client complains to the nurse that she is experiencing a brassy taste in her mouth when taking the medication. Which instruction should the nurse provide to the client?

• Dilute the medication in 8 ounces of water.
• Report the symptom to the health care provider (HCP).
• Continue to take the medication because the symptom is normal.
• Take one half dose of the prescribed medication for the next 2 days.

Explanation: Answer reason: Potassium iodide solutions can cause an unpleasant metallic/brassy taste and local irritation because they are concentrated and irritating to the oral mucosa. Diluting the dose in a full glass of water reduces direct contact with the mouth and throat and improves tolerability while maintaining the intended preoperative iodine effect. This symptom alone is not a hallmark of iodine toxicity (iodism), which would be more concerning with findings like severe mucosal irritation, salivary gland swelling, or systemic symptoms, so immediate provider notification is not the best first instruction. Advising dose reduction is unsafe because it alters the prescribed regimen and could decrease therapeutic effectiveness before thyroid surgery.

A nurse is providing education to a school-age child newly diagnosed with asthma about how to use a metered-dose inhaler. In which order should the nurse teach the child to perform the following steps? (All steps must be used.)?

• Shake the inhaler while holding it upright.
• Slowly inhale the medication.
• Position the mouthpiece in the mouth.
• Hold the breath for 5 to 10 seconds.

Explanation: Answer reason: Proper metered-dose inhaler technique requires preparing the canister first so the medication is adequately mixed and the delivered dose is accurate. After shaking, the child should place the mouthpiece in the mouth to ensure a sealed path for aerosol delivery. The medication should then be inhaled slowly during actuation to maximize deposition in the lower airways rather than the oropharynx. Finally, holding the breath for 5–10 seconds increases time for particle sedimentation and improves lung absorption, whereas skipping the breath-hold reduces therapeutic effect.

The nurse has given instructions to a client who has just been prescribed cholestyramine (Questran). Which statement by the client indicates a need for further instructions?

• "I will continue taking vitamin supplements."
• "This medication will help lower my cholesterol."
• "This medication should only be taken with water."
• "A high-fiber diet is important while taking this medication."

Explanation: Answer reason: " Cholestyramine is a bile acid sequestrant supplied as a powder that must be mixed thoroughly with fluid and should not be taken dry; it can be mixed with water or other noncarbonated beverages/soft foods to improve tolerance. Saying it should only be taken with water reflects incorrect administration teaching and increases the risk the client will take it improperly or avoid doses. It is appropriate that the client expects cholesterol lowering, since this medication reduces LDL by binding bile acids in the gut. Constipation is common, so emphasizing dietary fiber (and adequate fluids) is appropriate, and vitamin supplementation may be needed because it can reduce absorption of fat-soluble vitamins.

For a postoperative client, the health care provider (HCP) prescribed multimodal therapy, which includes acetaminophen, nonsteroidal anti-inflammatory drugs, as needed (PRN) opioids, and nonpharmaceutical interventions. The client continuously asks for the PRN opioid, and the nurse suspects that the client may have a drug abuse problem. Which action by the nurse is best?

• Administer acetaminophen and spend extra time with the client.
• Explain that opioid medication is reserved for moderate to severe pain.
• Give the opioid because client deserves relief and drug abuse is unconfirmed.
• Ask the HCP to validate suspicions of drug abuse and alter the opioid prescription.

Explanation: Answer reason: Pain management should be based on the client’s reported pain and the ordered regimen, not on unverified assumptions about substance use. A PRN opioid order indicates it may be administered when pain criteria are met, and withholding it due to suspicion risks undertreating pain and causing physiologic stress and delayed recovery. Clients with substance use disorder can still have legitimate acute postoperative pain and require appropriate analgesia with monitoring for oversedation and respiratory depression. Teaching about appropriate opioid use can occur, but it should not replace timely analgesia when indicated. Changing the prescription based solely on suspicion is not the nurse’s role and can introduce bias and unsafe pain control.

A client with type 1 diabetes has a prescription for 30 units of insulin glargine at bedtime. Fingerstick blood glucose measurements are prescribed before meals and at bedtime with regular insulin based on a sliding scale. At 9 PM, the client's blood glucose measurement is 180 mg/dL (10.0 mmol/L). What action should the nurse take? Click on the exhibit button for additional information?

• Administer 30 units of glargine; give the client a snack, then administer 2 units of regular insulin [9%]
• Administer 30 units of glargine and 2 units of regular insulin in 2 different injections [50%]
• Mix 30 units of glargine with 2 units of regular insulin in the same syringe, drawing up the glargine first [7%]
• Mix 30 units of glargine with 2 units of regular insulin in the same syringe, drawing up the regular insulin first [32%]

Explanation: Answer reason: A bedtime glucose of 180 mg/dL warrants correction with short-acting regular insulin per sliding scale while still giving the prescribed basal dose to maintain overnight glycemic control. Giving both agents as separate injections preserves predictable pharmacokinetics and reduces risk for unexpected hypo/hyperglycemia. Mixing either order is unsafe with glargine, and adding an extra snack is not indicated solely to “cover” a corrective dose when the glucose is elevated.

An older adult client takes multiple prescription medications plus several over-the-counter medications. Which intervention by the clinic nurse is most important in reducing the risk for drug interactions?

• Assist client with making a list of all medications, doses, and times to be taken
• Encourage client to obtain all prescription medications from the same pharmacy
• Have client bring all medications taken regularly or occasionally to each appointment
• Instruct client to use a pill organizer to separate pills by day and time

Explanation: Answer reason: Using one pharmacy allows automated interaction screening across all prescriptions and enables the pharmacist to reconcile duplications, contraindications, and high-risk combinations in real time. A medication list and “brown bag” review improve accuracy of what the patient is taking, but they rely on patient recall/bringing items and do not provide the same continuous, system-level interaction checking at the point of dispensing. A pill organizer helps adherence but does not reduce interaction risk and can obscure identification of individual products.

A nurse is preparing to administer ophthalmic solution to a client. Which of the following is an appropriate action by the nurse?

• Instill the drops into the inner canthus.
• Instill the drops into the center of the upper conjunctival sac .
• Hold the ophthalmic solution2 cm (3/4 in) above the lower conjunctival sac.
• Ask the client to look down when instilling the solution.

Explanation: Answer reason: Safe eye-drop administration places medication into the lower conjunctival sac without contaminating the dropper tip or traumatizing the cornea. Positioning the dropper a short distance above the sac allows accurate delivery while preventing the bottle from touching the eye or eyelashes, reducing infection risk. Drops are not placed in the inner canthus because this increases immediate drainage through the nasolacrimal duct and reduces local effect. Using the upper conjunctival sac and client looking down are less appropriate because the cornea is more exposed and blinking/rolling can increase discomfort and misplacement.

The nurse is preparing to administer a first dose of prescribed pentamidine isethionate intravenously to a client. Before administering the dose, which safety measure should the nurse consider for this client?

• Assign to a private room.
• Establish a supine position.
• Place on respiratory precautions.
• Assist to a semi-Fowler's position.

Explanation: Answer reason: IV pentamidine can cause significant hypotension, particularly with initial dosing and if infused too rapidly, so a preventive safety step is to position the client to support blood pressure and reduce syncope/fall risk. Keeping the client supine helps maintain venous return and improves hemodynamic stability during administration. This also facilitates close monitoring and rapid intervention if dizziness, diaphoresis, or BP drop occurs. A semi-Fowler’s position may worsen orthostatic effects and does not address the primary immediate infusion-related risk.

A nurse is teaching a client with type 1 diabetes mellitus who jogs daily about the preferred sites for insulin absorption. What is the most appropriate site for a client who jogs?

• Arms
• Legs
• Abdomen
• Iliac crest

Explanation: Answer reason: A client who jogs daily should avoid injecting into areas that will be heavily exercised (especially the legs) to reduce exercise-induced rapid absorption and hypoglycemia risk. The abdominal subcutaneous tissue provides the most consistent and predictable absorption among common sites and is least affected by leg muscle use during jogging. Injecting into the legs is a common distractor because it can significantly accelerate absorption during running. Using a consistent site with rotation within that area supports stable glycemic control and safer exercise.

What should you do to keep your teeth clean?

• Brush your teeth twice a day
• Eat a lot of candy
• Never visit the dentist
• Drink soda every day

Explanation: Answer reason: Regular brushing reduces bacterial biofilm and food debris that otherwise produce acid and inflammation, supporting oral tissue integrity and preventing halitosis. The other options increase exposure to sugar and acid or reduce preventive care, all of which promote enamel demineralization and periodontal disease. In basic health teaching, consistent oral hygiene behaviors are prioritized because they are effective, low risk, and feasible for most patients.

The nurse precepts a nursing student caring for a client with glaucoma and observes the student administer timolol maleate, an ophthalmic medication. Which student action indicates that further instruction is needed?

• Instructs client to close eyelid and move eye around; applies pressure to the lacrimal duct for 30-60 seconds
• Pulls lower eyelid down gently with thumb or forefinger against bony orbit to expose the conjunctival sac
• Removes dried secretions with moistened sterile gauze pads by wiping from the outer to inner canthus
• Rests hand on client's forehead and holds dropper 1-2 cm (1/2-3/4 in) above the conjunctival sac

Explanation: Answer reason: Wiping from outer to inner canthus increases the chance of contaminating the lacrimal duct and spreading organisms across the eye. The other actions reflect correct eye-drop administration technique, including creating a conjunctival pocket, stabilizing the hand and keeping the dropper above the sac, and using nasolacrimal occlusion to reduce systemic absorption of timolol.

A nurse giving post-operative discharge instructs a patient who had abdominal surgery, when teaching the patient about wound healing all of the following are the true EXCEPT?

• Wound may feel tightly or itchy as healing occurs
• Scabs promote infection of the new skin underneath them
• Numbness or a slight pulling sensation is normal
• Wound should not have any drainage

Explanation: Answer reason: Scab formation is generally a protective barrier over the wound surface and helps shield underlying tissue from external contamination rather than causing infection by itself. Mild numbness or a pulling sensation can occur from tissue edema, healing nerves, and scar contraction after abdominal incisions. Infection risk is more strongly suggested by increasing redness, warmth, pain, swelling, purulent drainage, or fever, not by the presence of a scab alone.

The nurse is instructing a 53 year-old male client with newly-diagnosed type 2 diabetes how to care for his feet at home. Which statement indicates that the client understands?

• If I cut my foot, I'll just apply antibiotic ointment.
• I'll dry my feet very well after every shower.
• It's okay to go barefoot in my own home.
• Every Sunday evening, I will carefully inspect my feet.

Explanation: Answer reason: Diabetes increases risk for neuropathy and impaired circulation, making skin breakdown and infection more likely, so meticulous daily foot hygiene is essential. Thoroughly drying the feet (especially between toes) reduces moisture-related maceration and fungal growth that can lead to fissures and ulcers. In contrast, relying on self-treatment with ointment after a cut delays needed evaluation, and going barefoot increases risk of unnoticed injury. The “inspect weekly” statement is insufficient because feet should be inspected daily to catch problems early.

A nurse is caring for a female client comes to the provider's office for treatment of acne vulgaris on her cheeks. Which of the following should the nurse reinforce in the teaching for this client?

• Use friction when washing the face.
• Adhere to strict dietary reduction of foods prepared with oil.
• Express the larger comedones periodically.
• Use a new cosmetic pad each time she applies makeup.

Explanation: Answer reason: Acne care teaching emphasizes gentle skin care and reducing occlusive/contaminated products that can worsen follicular blockage and inflammation. Using a fresh applicator helps limit reintroducing oil, bacteria, and old makeup residue to the skin, supporting better acne control and reducing secondary infection risk. Friction and scrubbing can irritate follicles and increase inflammation, often worsening lesions. Strict avoidance of oily foods is not an evidence-based primary intervention for acne, and manual expression of comedones increases risk of skin trauma, infection, and scarring.

A male client who is very depressed exhibits psychomotor retardation, a flat affect, and apathy. The nurse observes the client to be in need of grooming and hygiene. Which of the following nursing actions is most appropriate?

• Explaining the importance of hygiene to the client.
• Asking the client if he is ready to shower.
• Waiting until the client’s family can participate in the client’s care.
• Stating to the client that it’s time for him to take a shower.

Explanation: Answer reason: Severe depression with psychomotor retardation and apathy reduces initiation, energy, and ability to make decisions, so the nurse should provide simple, concrete structure and direction for basic self-care. A clear, matter-of-fact prompt lowers the cognitive and motivational burden and helps the client complete necessary hygiene despite limited drive. Offering an open-ended choice can lead to nonaction because the client may not be able to initiate even if he agrees in principle. Teaching about hygiene or delaying care until family involvement does not address the immediate self-care deficit and may worsen functional decline.

The nurse is caring for a patient with Meniere's Syndrome. Which of the following nursing interventions is of the highest priority when caring for this patient?

• Discussing treatment options
• Initiating fall risk measures
• Keeping the patient calm during an episode
• Providing teaching on potential causes

Explanation: Answer reason: Meniere’s disease causes episodic vertigo with imbalance, making immediate injury prevention the top priority. Implementing fall precautions (assist with ambulation, keep bed low, call light within reach, reduce environmental hazards) directly addresses the most time-sensitive risk. Calming measures can support symptom control, but they do not mitigate the immediate danger of a fall as reliably as safety interventions. Teaching and discussing long-term management are important but are lower priority than preventing acute harm.

Which of the following children would the nurse identify as a priority for having the greatest risk for choking and suffocating?

• A toddler playing with his 9-year-old brother's construction set
• A 5-year-old eating yogurt for a snack
• An infant covered with a small blanket and asleep in her crib
• A 3-year-old drinking a glass of juice

Explanation: Answer reason: A construction set intended for an older child commonly contains small components that easily obstruct a toddler’s airway. In contrast, yogurt and juice are low choking-risk textures when appropriately supervised and sipped, and they do not involve small solid objects that can lodge in the trachea. While safe sleep concerns exist with loose bedding, the most immediate and high-probability choking hazard among the options is access to small toy parts.

A hospitalized 72 year-old man who uses a walker is receiving diuretic medication and must use the bathroom several times each night. To promote the safety of the patient which is the most appropriate nursing action?

• Keep the side rails up
• Leave the bathroom light on
• Provide a bedside commode
• Withhold the patient's diuretic medication

Explanation: Answer reason: Placing toileting within immediate reach reduces distance walked, time pressure, and chances of tripping or losing balance. Keeping side rails up can be considered a restraint and may increase injury risk if the patient tries to climb over them. Withholding a prescribed diuretic is outside routine nursing scope without an order and could worsen fluid overload or hypertension; environmental and toileting modifications are the safer first-line intervention.

The client diagnosed with a closed head injury is admitted to the rehabilitation department. Which medication order would the nurse question?

• A subcutaneous anticoagulant.
• An intravenous osmotic diuretic.
• An oral anticonvulsant.
• An oral proton pump inhibitor.

Explanation: Answer reason: After a closed head injury, any medication that increases bleeding risk must be scrutinized because even small increases in intracranial bleeding can rapidly worsen neurologic status and raise intracranial pressure. Anticoagulants can precipitate or expand an intracranial hemorrhage, particularly if there is an occult bleed or cerebral contusion. By contrast, osmotic diuretics may be used to manage elevated intracranial pressure, anticonvulsants are commonly used for seizure prophylaxis after head injury, and acid suppression may be used for stress-ulcer prophylaxis. The safest nursing action is to question anticoagulation unless the prescriber clearly documents an overriding indication with appropriate neuroimaging and risk-benefit assessment.

The home care nurse visits a client at home 4 days after a plaster cast has been applied. Which statement by the client would indicate a need for further teaching about the cast?

• I need to check for any hot spots on the cast.
• I need to always keep my cast away from any hard surfaces.
• I need to inspect the cast for any drainage through the cast or cast opening.
• I need to look for any musty unpleasant odor coming from the cast or at the end of the cast.

Explanation: Answer reason: Plaster casts need to be supported on a firm surface (often on a pillow) to prevent cracking, denting, and loss of immobilization, especially while they are drying in the first 24–48 hours. Avoiding all hard surfaces is incorrect and could lead to poor support and increased risk of cast damage and misalignment of the injured extremity. Monitoring for localized warmth (“hot spots”), drainage, or foul/musty odor are appropriate because they can signal pressure injury, infection, or skin breakdown under the cast and require prompt evaluation. Therefore this statement shows misunderstanding of basic cast care and safety.

A client with a short leg plaster cast reports intense itching under the cast. The nurse provides instructions to the client regarding relief measures for the itching. Which statement by the client indicates an understanding of the measures used to relieve the itching?

• "I can use the blunt part of a ruler to scratch the area."
• "I can trickle small amounts of water down inside the cast."
• "I need to obtain assistance when placing an object into the cast for the itching."
• "I can use a hair dryer on the low setting and allow the air to blow into the cast."

Explanation: Answer reason: " Itching under a cast should be managed without introducing objects or moisture because both can cause skin injury, pressure areas, and infection that may go unnoticed. Cool air flow helps reduce heat and humidity under the cast and can provide symptomatic relief without disrupting skin integrity. Scratching with any object (even “blunt”) risks abrasions and ulceration beneath the cast. Adding water increases moisture, maceration, and odor and can weaken plaster and promote microbial growth.

The nurse mentor is observing a new nurse change the ties for a client with a tracheostomy. Which action, if performed by the new nurse, indicates a need for further instruction?

• Auscultating chest sounds before the procedure
• Taping tracheal retention sutures above and below the stoma
• Positioning the client in a supine position before the procedure
• Cleaning under the tracheostomy faceplate after cleaning the stoma

Explanation: Answer reason: Lying supine can worsen breathing by decreasing lung expansion and can increase the chance of secretions pooling and aspiration, especially while manipulating the tracheostomy. The preferred position is semi-Fowler’s or Fowler’s to support oxygenation and patient tolerance during tie changes. While assessing breath sounds and performing stoma/faceplate hygiene are appropriate supportive actions, unsafe positioning during airway care is the key error requiring correction.

The nurse notes that a client sitting in a chair has not gotten up in 1 hour. The client does not respond to verbal directions, and her arm has been extended over the armrest for 30 minutes. Which of the following should the nurse do next?

• Assist the client out of the chair to lead her back to bed.
• Give p.r.n.-ordered doses of haloperidol (Haldol) and lorazepam (Ativan).
• Ask the client to describe what is being experienced right now.
• Sit quietly with the client until she begins to respond.

Explanation: Answer reason: The priority is immediate physical safety and prevention of injury when a client is unresponsive to verbal direction and has maintained an abnormal position long enough to risk impaired circulation, nerve compression, or a fall. Repositioning and assisting her to a safe place addresses the most urgent risk while allowing the nurse to assess responsiveness and potential causes (e.g., medication effect, catatonia, neurologic change). Administering PRN antipsychotic/benzodiazepine is not first-line here because it can worsen sedation and increase fall risk without first addressing the unsafe positioning. Therapeutic communication or waiting may be appropriate later, but delaying action leaves the client at ongoing risk for pressure injury and neurovascular compromise.

Which medication is used to treat type 2 diabetes?

• Atorvastatin
• Metformin
• Cetirizine
• Losartan

Explanation: Answer reason: This drug decreases gluconeogenesis in the liver and increases peripheral insulin sensitivity, lowering fasting and postprandial glucose without causing hypoglycemia when used alone. It is widely recommended as initial pharmacotherapy alongside lifestyle modification for most adults with type 2 diabetes. By contrast, a statin treats dyslipidemia, an ARB treats hypertension/proteinuria, and an antihistamine treats allergic symptoms, none of which directly lower blood glucose.

Sedative effect sabse zyada kis drug me hota hai?

• Fexofenadine
• Loratadine
• Diphenhydramine
• Desloratadine

Explanation: Answer reason: This drug is also significantly anticholinergic, which further contributes to drowsiness, impaired concentration, and psychomotor slowing. In contrast, second-generation antihistamines like fexofenadine, loratadine, and desloratadine are more peripherally selective and have minimal CNS penetration, so they are far less sedating. Therefore, among the listed options, the one expected to cause the most sedation is the first-generation agent.

Which of the following medications is contraindicated during pregnancy due to its potential to cause fetal thrombocytopenia?

• Warfarin and heparin
• Ibuprofen
• Aspirin
• Valproic acid

Explanation: Answer reason: Warfarin readily crosses the placenta and is classically avoided in pregnancy because it can produce fetal anticoagulation and hemorrhagic effects. Heparin is associated with heparin-induced thrombocytopenia as an immune-mediated adverse effect and is treated as a key thrombocytopenia-related risk in anticoagulant selection questions. By contrast, NSAIDs like ibuprofen/aspirin are more associated with fetal renal effects and premature ductus arteriosus closure later in pregnancy rather than being the prototypical cause of fetal thrombocytopenia in exam framing.

A patient with hypertension and gout is prescribed losartan. The beneficial effect on uric acid is?

• Uricosuric effect (lowers serum uric acid)
• Increases uric acid
• Causes gout flares
• No effect

Explanation: Answer reason: This makes it a preferred antihypertensive choice for patients with gout compared with agents that raise uric acid (e.g., thiazide diuretics). The beneficial effect is therefore lowering uric acid rather than increasing it or having no effect. It does not characteristically precipitate gout flares as a direct pharmacologic effect.

What is the primary use of Artemether injection?

• Malaria treatment
• Bacterial infection treatment
• Viral infection treatment
• Fungal infection treatment

Explanation: Answer reason: The injectable formulation is used for malaria, particularly when oral therapy is not feasible or in severe/complicated cases as part of artemisinin-based treatment strategies. It is not an antibiotic, antiviral, or antifungal and therefore would not be expected to target typical bacterial, viral, or fungal pathogens. The key testable point is matching the drug class (artemisinin derivatives) with its primary indication (malaria).

Which antibiotic causes red-man syndrome if infused too quickly?

• Ceftriaxone
• Penicillin
• Vancomycin
• Gentamicin

Explanation: Answer reason: Rapid IV administration of this drug can cause flushing, pruritus, erythema (especially face/neck/upper torso), and sometimes hypotension. The risk is reduced by slowing the infusion rate (typically at least 60 minutes, longer for higher doses) and, when needed, premedicating with an antihistamine. The other listed antibiotics are associated with different hallmark toxicities (e.g., beta-lactam allergy with penicillin; nephro/ototoxicity with gentamicin) rather than infusion-rate–dependent flushing.

Statins lower LDL primarily by?

• Binding bile acids
• Upregulating hepatic LDL receptors
• Inhibiting intestinal cholesterol absorption
• Increasing biliary excretion

Explanation: Answer reason: This triggers increased expression of LDL receptors on the liver cell surface, which boosts clearance of circulating LDL particles from the blood—this is the main mechanism responsible for LDL reduction. In contrast, binding bile acids is the primary action of bile acid sequestrants, and inhibiting intestinal cholesterol absorption is the mechanism of ezetimibe. Increased biliary excretion is not the primary pathway by which statins lower LDL in clinical practice.

Which of the following is a commonly used antacid?

• Famotidine
• Calcium carbonate
• Omeprazole
• Ranitidine

Explanation: Answer reason: This option is a classic over-the-counter antacid that raises intragastric pH by acid neutralization. In contrast, famotidine and ranitidine are H2-receptor antagonists that reduce acid secretion rather than neutralize existing acid. Omeprazole is a proton pump inhibitor that suppresses acid production more slowly and is not classified as an antacid.

Which of the following is a statin drug?

• Warfarin
• Aspirin
• Simvastatin
• Ibuprofen

Explanation: Answer reason: Among the choices, only this drug name ends with the characteristic “-statin” suffix and belongs to the statin class. Warfarin is an anticoagulant (vitamin K antagonist), and aspirin and ibuprofen are NSAIDs/antiplatelet-analgesic agents rather than cholesterol-lowering drugs. Therefore it is the only option that matches the pharmacologic class being asked.

Which drug is used to treat epilepsy?

• Aspirin
• Phenytoin
• Propranolol
• Metformin

Explanation: Answer reason: Phenytoin is a classic antiseizure medication that primarily blocks voltage-gated sodium channels, helping prevent seizure propagation (notably in focal and generalized tonic-clonic seizures). Aspirin is an analgesic/antiplatelet, propranolol is a beta-blocker used for cardiovascular conditions and tremor, and metformin is an antihyperglycemic for type 2 diabetes. Therefore, the only option that directly treats epilepsy is the antiseizure agent listed.

All these antihypertensive drugs are safe in pregnancy, except which?

• Labetalol
• Ramipril
• Nifedipine
• Methyldopa

Explanation: Answer reason: This leads to fetal renal dysgenesis with oligohydramnios, pulmonary hypoplasia, growth restriction, and neonatal renal failure, especially with 2nd/3rd trimester exposure. In contrast, labetalol, nifedipine, and methyldopa are standard first-line/commonly used agents for chronic hypertension or acute BP control in pregnancy due to better fetal safety profiles. Therefore the ACE inhibitor listed is the unsafe choice.

Which drug is a direct-acting vasodilator?

• Hydralazine
• Aspirin
• Phenytoin
• Metformin

Explanation: Answer reason: Hydralazine fits this mechanism and is classically categorized as a direct arteriolar vasodilator used in hypertension (including in pregnancy) and in selected heart failure regimens. Aspirin is an NSAID/antiplatelet agent, phenytoin is an antiepileptic sodium-channel blocker, and metformin is an antihyperglycemic; none are primary direct vasodilators. A common testable consequence of hydralazine’s arteriolar dilation is reflex sympathetic activation, leading to tachycardia and fluid retention, often prompting combination with a beta-blocker and diuretic.

Which drug is a direct renin inhibitor?

• Aliskiren
• Losartan
• Lisinopril
• Amlodipine

Explanation: Answer reason: This mechanism uniquely matches one medication in the list. In contrast, losartan is an ARB (blocks angiotensin II receptors) and lisinopril is an ACE inhibitor (blocks conversion of angiotensin I to II), which are downstream targets. Amlodipine is a dihydropyridine calcium channel blocker and does not act on the RAAS pathway.

The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) and a significant family history of coronary artery disease. Which of the following prescriptions by the health care provider would treat a major modifiable risk factor of coronary artery disease?

• Prednisone
• Fluticasone/salmeterol
• Albuterol
• Atorvastatin

Explanation: Answer reason: Major modifiable risk factors for coronary artery disease include dyslipidemia, hypertension, diabetes, and smoking, and lowering LDL cholesterol reduces atherosclerotic event risk. A statin directly treats hyperlipidemia by inhibiting HMG-CoA reductase, lowering LDL and stabilizing plaque, which addresses a key modifiable CAD risk factor. The other options are COPD therapies (systemic steroid, ICS/LABA, and SABA) and do not target lipid-driven atherosclerosis. In a patient with strong family history, lipid-lowering therapy is a high-yield preventive intervention when indicated by risk assessment.

Which symptom of hypoglycemia will be present in a patient even he's taking beta blocker?

• Tachycardia
• Sweating
• Tremors
• Palpitation

Explanation: Answer reason: Diaphoresis is largely mediated by sympathetic cholinergic (muscarinic) pathways rather than beta receptors, so it tends to remain a reliable sign. Tremor is more beta-2 mediated and can also be reduced, making it less dependable than diaphoresis. Therefore, persistent sweating is the best expected symptom even when a patient is taking a beta-blocker.

What is the primary function of the drug albuterol?

• To reduce fever
• To treat bacterial infections
• To reduce inflammation and pain
• To treat asthma

Explanation: Answer reason: This directly addresses acute bronchospasm and reversible airflow obstruction seen in asthma (and COPD), improving wheeze and shortness of breath. It does not treat infection or fever because it has no antimicrobial or antipyretic mechanism. It also is not primarily an anti-inflammatory analgesic; airway inflammation is targeted by corticosteroids rather than SABAs.

What are the potential side effects of antacids?

• Nausea and vomiting
• Diarrhea and constipation
• Abdominal pain and bloating
• Headache and dizziness

Explanation: Answer reason: Magnesium-containing antacids commonly cause osmotic diarrhea, while aluminum-containing antacids tend to cause constipation by slowing intestinal motility. Many OTC antacid products combine magnesium and aluminum salts to blunt either extreme, highlighting these as the classic side effects tested. Other listed symptoms can occur nonspecifically, but they are less characteristic and less predictive of antacid type.

What is the primary use of nitroglycerin?

• Treatment of angina pectoris
• Management of diabetes
• Control of seizures
• Treatment of hypertension

Explanation: Answer reason: Its predominant clinical benefit in acute angina is venodilation that reduces preload and myocardial oxygen demand, quickly relieving ischemic chest pain; it can also dilate coronary arteries and improve perfusion. Diabetes management and seizure control are unrelated to its mechanism and therapeutic class. Although it can lower blood pressure, that effect is secondary and not its primary indication in routine practice compared with angina relief.

Which analgesic drug is often used to treat nerve pain?

• Nonsteroidal anti-inflammatory drugs (NSAIDs)
• Acetaminophen
• Opioids
• Antidepressants

Explanation: Answer reason: Certain antidepressants (especially TCAs like amitriptyline and SNRIs like duloxetine) enhance descending inhibitory pathways via serotonin and norepinephrine, making them first-line options for many neuropathic pain syndromes. NSAIDs and acetaminophen mainly target inflammatory/prostaglandin-mediated nociceptive pain and are often inadequate for nerve pain. Opioids can provide analgesia but are not typically preferred for chronic neuropathic pain due to limited long-term benefit and higher risk of dependence and adverse effects.

Which antibiotic class can cause severe photosensitivity reactions?

• Aminoglycosides
• Tetracyclines
• Fluoroquinolones
• Sulfonamides

Explanation: Answer reason: This class is classically associated with pronounced sunburn-like reactions, so patients should be counseled on sun avoidance and high-SPF protection. Aminoglycosides are better known for nephrotoxicity and ototoxicity rather than UV reactions. Although some fluoroquinolones and sulfonamides can also cause photosensitivity, it is most strongly and commonly tested with this class.

Which drug is the first-line treatment for Type 2 Diabetes?

• Metformin
• Atorvastatin
• Amoxicillin
• Diazepam

Explanation: Answer reason: This medication fits that role and is widely recommended as first-line for most nonpregnant adults when not contraindicated (notably severe renal impairment). It is weight-neutral to modestly weight-reducing and has favorable cardiometabolic effects compared with many alternatives. A common distractor here is a statin, which is used for dyslipidemia and cardiovascular risk reduction but does not treat hyperglycemia.

What is the main therapeutic use of acyclovir?

• Treatment of herpes virus infections
• Management of diabetes
• Prevention of blood clots
• Control of blood glucose

Explanation: Answer reason: Clinically it is used to treat HSV-1/HSV-2 infections (e.g., genital herpes) and varicella-zoster infections (chickenpox, shingles), reducing symptom duration and viral shedding when started early. The diabetes-related options are incorrect because acyclovir has no role in insulin secretion, insulin sensitivity, or glucose regulation. It also does not affect coagulation pathways, so it is not used for prevention of blood clots.

Which class of drugs is contraindicated in patients with a history of liver disease?

• NSAIDs
• Antihypertensives
• Anticoagulants
• Antifungals

Explanation: Answer reason: In a patient with pre-existing liver disease, reduced hepatic reserve increases the likelihood of clinically significant transaminitis, hepatitis, or liver failure when exposed to hepatotoxic agents. This makes the antifungal class (particularly azoles and some other systemic agents) a high-risk choice and often contraindicated or requires strict avoidance depending on severity. In contrast, NSAIDs are more classically avoided in liver disease due to bleeding/renal effects, but they are not uniformly contraindicated as a class to the same extent as hepatotoxic systemic antifungals. The key safety principle is to avoid drugs with strong hepatic metabolism and hepatotoxic potential when hepatic function is impaired.

Furosemide belongs to which class of drugs?

• Beta blockers
• Loop diuretics
• Calcium channel blockers
• ACE inhibitors

Explanation: Answer reason: This pharmacologic effect is characteristic of loop diuretics and explains its common use for edema (e.g., heart failure) and hypertension when significant fluid removal is needed. It also increases urinary calcium excretion, which further distinguishes it from thiazide diuretics. The other choices are antihypertensive classes with different targets (beta-adrenergic receptors, L-type calcium channels, or the renin-angiotensin system) and do not match furosemide’s renal tubular site of action.

What is the main therapeutic use of fluticasone?

• Treatment of asthma
• Management of diabetes
• Prevention of blood clots
• Control of blood glucose

Explanation: Answer reason: Its primary therapeutic role is maintenance therapy, not rapid relief during an acute attack. Diabetes and blood glucose control are not indications for this medication, and systemic corticosteroids more commonly worsen glycemic control rather than treat it. Prevention of blood clots is managed with antiplatelets or anticoagulants, not inhaled steroids.

What is the primary function of the drug fluticasone?

• To reduce inflammation and mucus production in the airways
• To treat bacterial infections
• To reduce fever
• To dilate the airways and improve breathing

Explanation: Answer reason: By decreasing airway inflammation, it reduces mucosal edema and downregulates mucus production, which lowers hyperresponsiveness and helps prevent exacerbations. It is not an antibiotic, so it does not treat bacterial infections, and it is not an antipyretic used primarily to reduce fever. Unlike short-acting beta-agonists, it does not provide rapid bronchodilation for acute symptom relief, so airway dilation is not its primary function.

What is a common side effect of rifampin?

• Weight gain, sedation, metabolic changes
• Nausea, diarrhea, headache
• Orange discoloration of bodily fluids, hepatotoxicity
• Hypotension, tachycardia, rash

Explanation: Answer reason: A clinically important adverse effect is liver injury, so patients require counseling about hepatitis symptoms and monitoring of liver enzymes, especially with other hepatotoxic TB drugs. Gastrointestinal upset can occur but is less distinctive and does not capture the key high-yield toxicity. Weight gain/sedation are not typical for this medication, and significant hypotension/tachycardia would suggest an acute reaction rather than the common expected effect.

What is a key adverse effect of carbamazepine?

• Hypertension, tachycardia, rash
• Hypoglycemia, weight loss, fever
• Rash, dizziness, bone marrow suppression
• Constipation, dry mouth, blurred vision

Explanation: Answer reason: g., dizziness, ataxia) and serious hematologic toxicity from bone marrow suppression. Clinically important complications include leukopenia, agranulocytosis, aplastic anemia, and thrombocytopenia, which is why CBC monitoring and infection/bleeding vigilance are emphasized. It is also associated with significant cutaneous reactions, ranging from mild rash to severe SJS/TEN (higher risk with certain HLA variants). The other options list effects more consistent with sympathomimetic toxicity, hypoglycemic drugs, or anticholinergic agents rather than this anticonvulsant/mood stabilizer.

Drug used for allergic rhinitis?

• Antihistamine
• Antibiotic
• Antacid
• Analgesic

Explanation: Answer reason: H1-receptor antagonists reduce these symptoms by blocking histamine’s effects on nasal and conjunctival tissues. Antibiotics target bacterial infections and do not treat an allergic mechanism. Antacids and analgesics may address GI acidity or pain, but they do not address the histamine-mediated pathophysiology of allergic rhinitis.

What is the mechanism of action of opioids?

• Blockade of calcium channels
• Inhibition of carbonic anhydrase
• Activation of opioid receptors
• Blockade of beta-adrenergic receptors

Explanation: Answer reason: Receptor activation inhibits adenylyl cyclase, closes presynaptic voltage-gated calcium channels, and opens postsynaptic potassium channels, decreasing substance P and glutamate transmission in pain pathways. This produces analgesia along with predictable class effects such as sedation and respiratory depression. Calcium-channel blockade alone is not the defining pharmacologic mechanism (it is downstream of receptor activation), while carbonic anhydrase inhibition and beta-adrenergic blockade describe other drug classes.

A patient with tuberculosis is on isoniazid. He should receive supplemental?

• Vitamin D
• Folic acid
• Pyridoxine (vitamin B6) to prevent neuropathy
• Vitamin B12

Explanation: Answer reason: Supplementing vitamin B6 reduces the risk of paresthesias, numbness, and other neurotoxicity, especially in patients with risk factors such as malnutrition, pregnancy, HIV, diabetes, alcoholism, or renal failure. This supplementation supports normal neurotransmitter synthesis and nerve function while allowing continued effective TB therapy. Other vitamins listed are not routinely used specifically to prevent isoniazid-associated neuropathy.

What is the drug of choice for the prophylaxis of malaria in travelers to areas with chloroquine-resistant Plasmodium falciparum?

• Chloroquine
• Doxycycline
• Atovaquone-proguanil
• Mefloquine

Explanation: Answer reason: falciparum, chemoprophylaxis requires an agent active against resistant strains in endemic regions. This option is a standard first-line regimen for travelers because it is highly effective and typically well tolerated, with a short post-travel continuation period compared with some alternatives. Chloroquine is ineffective in chloroquine-resistant areas, making it an unsafe choice for prevention. While doxycycline and mefloquine are also acceptable alternatives, selection commonly favors this option due to its favorable balance of efficacy, resistance coverage, and practicality for many travelers.

What is the primary function of the drug theophylline?

• To relax the muscles in the airways and improve breathing
• To reduce inflammation and mucus production in the airways
• To treat bacterial infections
• To reduce fever

Explanation: Answer reason: This directly addresses bronchospasm in conditions like asthma and COPD, so improving breathing through airway smooth-muscle relaxation is the primary therapeutic effect. Reducing airway inflammation and mucus is more characteristic of inhaled corticosteroids and some leukotriene modifiers rather than theophylline’s main action. It has no antibacterial or antipyretic mechanism, making those options clearly incorrect.

What is the mechanism of action of naloxone?

• Enhances serotonin reuptake
• Stimulates opioid receptors
• Inhibits GABA activity
• Opioid receptor antagonist

Explanation: Answer reason: This rapidly counteracts opioid-induced respiratory depression, sedation, and hypotension. Because it has a shorter duration than many opioids, recurrence of toxicity can occur and monitoring for re-sedation is important. The serotonin reuptake and GABA-related options describe mechanisms of other drug classes and do not reverse opioid effects.

Which drug is used to treat alcohol dependence?

• All of the above
• Disulfiram
• Naltrexone
• Acamprosate

Explanation: Answer reason: Naltrexone (opioid receptor antagonist) decreases rewarding effects and craving, acamprosate modulates glutamatergic/GABA balance to support abstinence, and disulfiram inhibits aldehyde dehydrogenase to produce unpleasant symptoms if alcohol is consumed. Because each listed medication is used for alcohol dependence in appropriate patients, the inclusive choice is most accurate. A common pitfall is thinking only aversive therapy is “treatment,” but relapse-prevention agents are standard first-line options as well.

Which drug is a cephalosporin antibiotic?

• Erythromycin
• Metronidazole
• Ceftriaxone
• Azithromycin

Explanation: Answer reason: This medication is a third-generation cephalosporin with strong gram-negative coverage and common clinical use in infections such as pneumonia, meningitis, and gonorrhea. By contrast, erythromycin and azithromycin are macrolides (protein synthesis inhibitors), and metronidazole is primarily used for anaerobes and certain protozoa via DNA strand breakage mechanisms. Identifying the drug class by name pattern is a high-yield pharmacology skill that guides expected coverage, allergy cross-reactivity considerations, and adverse-effect monitoring.

Which drug is an oral hypoglycemic agent?

• Ibuprofen
• Simvastatin
• Aspirin
• Glipizide

Explanation: Answer reason: This drug is a sulfonylurea that stimulates pancreatic beta cells to release insulin, thereby reducing serum glucose levels. The other options are not glucose-lowering antidiabetic drugs: ibuprofen and aspirin are NSAIDs/analgesics, and simvastatin is a lipid-lowering statin. A key safety consideration is hypoglycemia risk, especially with missed meals or in older adults.

Which the following is an example of Anti-hypetenive drug?

• Tolmetin
• Erymchhyin
• Carvedilol
• Vinorelbine

Explanation: Answer reason: This medication is a nonselective beta-blocker with additional alpha-1 blocking activity, which decreases heart rate/contractility and causes peripheral vasodilation, lowering blood pressure. Tolmetin is an NSAID for pain/inflammation and can worsen blood pressure control via sodium/water retention. Vinorelbine is a vinca alkaloid chemotherapy agent, not used for hypertension, and “Erymchhyin” appears to refer to an antibiotic (erythromycin), which is also not an antihypertensive.

A patient in on lithium. Which of the following is most likely to cause lithium toxicity when taken with lithium?

• Beta Blockers
• Diuretics
• Insulin
• Statins

Explanation: Answer reason: Lithium is handled by the kidneys similarly to sodium, so anything that lowers sodium or increases proximal sodium reabsorption reduces lithium clearance and raises serum levels. Diuretics—especially thiazides—promote sodium loss and thereby increase lithium reabsorption, making toxicity more likely. This interaction can occur even at usual lithium doses, particularly with dehydration or low-salt intake. By contrast, insulin and statins do not predictably raise lithium concentrations, and beta blockers are more associated with additive bradycardia/tremor effects rather than a classic increase in lithium level.

During an admission interview, a client reports to the nurse using several herbal and vitamin supplements daily, including echinacea. The nurse recognizes that echinacea is a popular herb used by clients primarily to?

• Boost vitality and libido.
• Improve weight loss.
• Enhance memory and cognition.
• Stimulate the immune system.

Explanation: Answer reason: Echinacea is commonly taken with the intent of preventing or shortening the duration of upper respiratory infections by promoting immune activity. This “immune boosting” use is the best-known and most frequently tested indication for the herb in nursing/pharmacology review. Options about libido, weight loss, or cognition are more characteristic of other supplements (e.g., ginseng for vitality, various stimulants for weight loss, ginkgo for cognition) rather than echinacea. Clinically, recognizing this purpose helps nurses screen for potential issues such as use in autoimmune conditions or with immunosuppressive therapies.

What is the primary indication for levofloxacin?

• Treatment of bacterial infections
• Management of osteoporosis
• Control of seizures
• Treatment of asthma

Explanation: Answer reason: The option describing bacterial infections directly matches its pharmacologic class and therapeutic purpose. Osteoporosis management is treated with agents like bisphosphonates or denosumab, not antibiotics. Seizure control requires antiepileptic drugs, and asthma is managed with bronchodilators and anti-inflammatory therapies rather than antibacterial agents unless a bacterial infection is present.

Which class of drugs is used to treat respiratory diseases by inhibiting the action of phosphodiesterase-4?

• Corticosteroids
• Beta-agonists
• Anticholinergics
• Phosphodiesterase-4 inhibitors

Explanation: Answer reason: PDE-4 inhibition increases intracellular cAMP in inflammatory cells, reducing release of pro-inflammatory mediators and helping control airway inflammation, particularly in COPD (e.g., roflumilast). The other listed respiratory drug classes act through different mechanisms: beta-agonists stimulate β2 receptors, anticholinergics block muscarinic receptors, and corticosteroids broadly alter gene transcription rather than directly inhibiting PDE-4. Therefore, the only option that directly fits the stated mechanism is the PDE-4 inhibitor class.

A 26-year-old male patient is prescribed Sulfasalazine (Azulfidine) to treat his ulcerative colitis. The patient's nurse discusses the side effects of the medication with the patient. Which of the following statements is false in regards to the side effects of this medication?

• This medicine may cause severe anemia
• This medicine will decrease the amount of sperm a man can produce
• This medicine may cause damage to the kidneys
• This medicine will permanently stain soft contact lenses yellow

Explanation: Answer reason: g., leukopenia, hemolytic anemia/agranulocytosis), so blood dyscrasias are a recognized serious risk. Renal injury is not a characteristic or commonly emphasized toxicity of sulfasalazine in standard nursing pharmacology teaching compared with its GI intolerance, hypersensitivity reactions, and marrow suppression. Therefore, the kidney-damage statement is the incorrect counseling point. A common distractor is assuming sulfonamide-related drugs primarily harm kidneys, but sulfasalazine’s more testable serious toxicity is hematologic.

The nurse has attended a staff education conference about fluoroquinolones. Follow-up is required if the nurse states that fluoroquinolones?

• Are available in oral and intravenous forms
• Cause elevation of liver enzymes
• Are narrow-spectrum agents
• Cause photosensitivity

Explanation: Answer reason: Therefore, describing them as narrow-spectrum reflects a misunderstanding that warrants follow-up teaching. The other statements align with common pharmacology teaching points: several fluoroquinolones have oral and IV formulations, they can be associated with hepatic enzyme elevations, and photosensitivity is a known adverse effect/precaution. A frequent exam trap is confusing fluoroquinolones with truly narrow-spectrum antibiotics like some penicillins aimed at limited organism groups.

A client with diabetes mellitus visits a health care clinic. The client’s diabetes mellitus previously had been well controlled with glyburide daily, but recently the fasting blood glucose level has been 180 to 200 mg/dL (10.2 to 11.4 mmol/L). Which medication, if added to the client’s regimen, may have contributed to the hyperglycemia?

• Prednisone
• Atenolol
• Phenelzine
• Allopurinol

Explanation: Answer reason: This effect can blunt the glucose-lowering benefit of sulfonylureas like glyburide, leading to new hyperglycemia after the steroid is started. Beta-blockers such as atenolol may mask hypoglycemia symptoms but are not a typical cause of sustained fasting hyperglycemia. Phenelzine and allopurinol do not commonly produce clinically significant hyperglycemia compared with systemic corticosteroids.

Which antibiotic should generally be avoided in children under 8 years due to risk of teeth discoloration?

• Amoxicillin
• Cefuroxime
• Azithromycin
• Tetracycline

Explanation: Answer reason: This risk is greatest when teeth are still developing, so they are generally avoided in children under 8 years and in pregnancy. Beta-lactams like amoxicillin and cefuroxime do not have this characteristic effect on tooth development. Macrolides such as azithromycin are typically considered alternatives when tetracyclines are contraindicated for age-related reasons.

Which of the following medications is contraindicated during pregnancy due to its potential to cause fetal bleeding?

• Heparin
• Warfarin
• Aspirin
• Clopidogrel

Explanation: Answer reason: It is also a known teratogen (fetal warfarin syndrome), making it generally contraindicated in pregnancy. In contrast, heparin does not cross the placenta due to its large molecular size, so it is the preferred anticoagulant when anticoagulation is needed in pregnancy. Antiplatelet agents like aspirin (dose-dependent) and clopidogrel can increase bleeding risk, but the classic medication contraindicated in pregnancy for fetal bleeding from placental transfer is warfarin.

How do cephalosporins like ceftriaxone work?

• Inhibition of bacterial cell wall synthesis
• Activation of beta-adrenergic receptors
• Blockade of calcium channels
• Inhibition of DNA gyrase

Explanation: Answer reason: Ceftriaxone, a third-generation cephalosporin, therefore works via inhibition of bacterial cell wall synthesis. In contrast, inhibition of DNA gyrase is the mechanism of fluoroquinolones, not cephalosporins. The beta-adrenergic receptor activation and calcium channel blockade options describe mechanisms of cardiovascular/respiratory drugs rather than antibiotics.

Which of the following medications is contraindicated during pregnancy due to its potential to cause neural tube defects?

• Folic acid
• Pyridoxine
• Riboflavin
• Valproic acid

Explanation: Answer reason: This risk is clinically significant enough that it is generally avoided in pregnancy when safer alternatives exist, especially for epilepsy and bipolar disorder. In contrast, folic acid is protective against neural tube defects and is recommended preconception and during early pregnancy. Pyridoxine and riboflavin are B vitamins without a typical association with causing neural tube defects at standard doses.

What is the mechanism of action of metformin?

• Decreases hepatic glucose production
• Stimulates insulin release
• Inhibits glucose absorption
• Enhances insulin receptor activity

Explanation: Answer reason: It also improves peripheral insulin sensitivity, increasing glucose uptake in muscle and adipose tissue, but it does not increase pancreatic insulin secretion. This is why it has a low risk of hypoglycemia when used alone, unlike agents that stimulate insulin release. Decreased intestinal glucose absorption can occur but is not the main tested mechanism compared with reducing hepatic glucose output.

An elderly patient had surgery two days for an intestinal obstruction. Vital signs at 10 am are temperature 37.5 c (99.5 f), heart rate 86, respiratory rate 16 blood pressure level 132/72 mm Hg, pain level of 4 on a scale of 0 to 10. The abdominal dressing is dry and intact. The nasal gastric tube to low intermittent suction. The patient is on strict input and output every two hours. At 12.20 pm, the patient complains abdominal pain, upon assessment the vital signs are temperature 37.5 C, heart rate 98, respiration rate 24, blood pressure level 146/ 88 mm Hg, pain level is 8 out of 10. The patient abdomen is distended and rigid, the dressing remains dry and intact. The nurse should first?

• Reposition the patient on the right side
• Irrigate the nasal gastric tube to check patency
• Medicate the patient for pain as ordered
• Increase the suction on his nasal gastric tube to high intermittent suction

Explanation: Answer reason: A nasogastric tube that is not patent can rapidly worsen gastric/intestinal distention, increasing pain and respiratory rate and raising the risk of vomiting/aspiration. Checking patency by irrigating per protocol is a rapid, focused intervention that addresses a reversible cause while guiding urgent escalation of care if symptoms persist. Giving analgesia first can mask worsening abdominal findings and delay recognition of deterioration. Increasing suction or repositioning are secondary steps and should follow confirmation that the tube is functioning correctly and provider notification as indicated.

The nurse is caring for a patient who is scheduled for elective cardioversion. The nurse is reviewing the patient's information and chart. Which of the following findings should the nurse inform the physician of immediately?

• The patient had their most recent dose of digoxin 48 hours ago
• The patient has been taking heparin for the past 5 weeks
• The patient has an atrial clot
• The patient has a history of atrial fibrillation

Explanation: Answer reason: A documented atrial clot is therefore an urgent contraindication to proceeding until the provider reassesses and anticoagulation/TEE-guided management is addressed. Anticoagulation history (e.g., heparin use) and a history of atrial fibrillation are expected considerations but do not, by themselves, represent an immediate stop-risk like a known thrombus. Holding digoxin prior to cardioversion may be relevant for dysrhythmia risk, but it is not as immediately dangerous as cardioverting in the presence of an atrial clot.

A 4-year old boy is recovering from abdominal surgery at the pediatric unit. As the nurse caring for the child, which activity would be most beneficial for him?

• Blowing bubbles
• Peek-a-boo
• Building blocks
• Playing with clay

Explanation: Answer reason: Postoperative children are at risk for atelectasis due to pain-limited ventilation and shallow breathing, so nursing care should promote deep breathing in a developmentally appropriate way. This play activity encourages slow, sustained exhalation and naturally increases depth of respiration, improving alveolar expansion and secretion mobilization without requiring complex instruction. It is feasible for a 4-year-old and minimizes strain on the abdominal incision compared with more active play. Peek-a-boo is more appropriate for infants, while blocks or clay may distract but do not specifically support pulmonary hygiene after surgery.

A woman who delivered a healthy baby 6 hours ago tells the nurse that she is having cramps in her legs. Upon further assessment, the nurse identifies leg pain on dorsiflexion. The nurse should?

• Tell the woman to massage the area.
• Apply warm compresses to the area.
• Instruct the woman on how to do ankle pumps.
• Notify the physician.

Explanation: Answer reason: Pain on dorsiflexion postpartum is a classic concerning finding for possible deep vein thrombosis, and suspected DVT requires prompt medical evaluation to prevent pulmonary embolism. The safest nursing action is to escalate care rather than perform interventions that could dislodge a clot. Massage is contraindicated because it may mobilize a thrombus, and warm compresses/ankle pumps are not appropriate while DVT is suspected. Prompt notification supports timely diagnostic testing and initiation of anticoagulation if indicated.

A nurse is evaluating a client with a temporary pacemaker. The patient’s ECG tracing shows each P wave followed by the pacing spike. The nurse’s best response is which of the following?

• Check the security of all connections and increase the milliampereage.
• Document the findings and continue to monitor the patient.
• Obtain a 12-lead ECG and a portable chest x-ray.
• Reposition the extremity and turn the patient to left side.

Explanation: Answer reason: A pacing spike should precede the depolarization it is intended to trigger; seeing a P wave before the spike indicates inappropriate timing (undersensing) or ineffective atrial pacing in a patient who is conducting intrinsically. The safest immediate nursing action is to troubleshoot the temporary pacer system, starting with verifying lead and generator connections and then adjusting output to ensure reliable capture if pacing is still required. Increasing the milliampere is a standard first-line adjustment when capture is questionable because it raises stimulus strength above threshold. Simply documenting/observing delays correction of a potentially unstable pacing problem, and additional diagnostics are secondary after immediate pacer function assessment and stabilization.

The wife of a man who sustained an eye injury calls the emergency department and speaks to the nurse. The wife reports that her husband was hit in the eye area by a piece of board while building a shed in the backyard. The nurse should advise the wife to take which immediate action?

• Call an ambulance.
• Apply ice to the affected eye.
• Irrigate the eye with cool water.
• Bring the husband to the emergency department.

Explanation: Answer reason: Blunt trauma to the eye/orbital area is managed initially by limiting swelling and pain while avoiding added pressure or manipulation that could worsen occult injury. Cold application helps reduce edema and hematoma formation, which can also improve subsequent assessment and comfort. Irrigation is appropriate for chemical or particulate foreign-body exposures, not a direct blow from a board. The client should still be evaluated urgently in the ED, but the immediate home action is local cold application while arranging prompt care and monitoring for vision changes or severe pain.

The nurse provides discharge instructions to a client with Cushing syndrome. The nurse advises the client to follow which instruction?

• "Monitor for dark, tarry stools."
• "Add iodized salt to your meals."
• "Monitor your weight once per week."
• "Avoid green, leafy vegetables."

Explanation: Answer reason: " Hypercortisolism increases the risk of gastrointestinal mucosal injury and bleeding, and chronic steroid exposure can mask early inflammatory symptoms, so patients need teaching to recognize occult blood loss. Dark, tarry stools indicate possible upper GI bleeding (melena) and warrant prompt evaluation. Adding salt would worsen sodium and water retention and hypertension commonly seen with this disorder. Weekly weight checks are too infrequent for monitoring fluid shifts; daily weights are typically emphasized instead.

The nurse has reinforced teaching with a client who was placed in skeletal traction 24 hours ago for a fractured femur. It would indicate a correct understanding of the teaching if the client?

• Rolls from side to side for linen changes
• Reports a change in the sensation in the leg
• Rests the feet against the end of the bed
• Adjusts the length of the rope used for traction

Explanation: Answer reason: This action supports rapid evaluation for impaired perfusion or nerve compression (e.g., developing compartment syndrome) before irreversible damage occurs. Rolling side to side can disrupt traction alignment and is not routinely done without maintaining body alignment and traction integrity. Resting feet against the end of the bed promotes foot drop, and adjusting traction ropes/weights is a nursing responsibility because changing the setup can negate the therapeutic pull and cause injury.

Which client should the nurse assess first after receiving the hand-off morning report?

• Client 1 day postoperative exploratory abdominal laparotomy who has a nasogastric tube and absent bowel sounds in 4 quadrants
• Client with a peripherally inserted central catheter who has a 5-cm (2-in) increase in external catheter length since yesterday
• Client with chronic diarrhea from malabsorption syndrome who is receiving 10% dextrose in water via a peripheral IV line
• Client with type 2 diabetes mellitus who is scheduled for discharge and has a hemoglobin A1C level of 9%

Explanation: Answer reason: This is an immediate patient-safety concern requiring prompt assessment, holding infusions, and notifying the provider for verification of tip location before further use. In contrast, absent bowel sounds on postoperative day 1 is commonly expected with ileus and is typically monitored unless accompanied by acute deterioration (e.g., severe pain, distention, instability). The other situations indicate ongoing management or education needs but are less time-critical than a potentially malpositioned central line.

The PN is caring for a client who is 24 hours postoperative for a hemicolectomy with temporary colostomy placement. On assessment, the PN finds that the stoma is dry and dark red. Based on this finding, what action should the nurse take?

• Notify the healthcare provider of the finding.
• Document the finding in the client’s record.
• Replace the pouch system over the stoma.
• Place petroleum gauze dressing on the stoma.

Explanation: Answer reason: A newly created stoma should appear moist and beefy red/pink, reflecting adequate perfusion. Dryness with a dark red color suggests impaired circulation and possible ischemia/necrosis, which is an early postoperative complication requiring prompt medical evaluation. Immediate escalation is the safest action because delayed intervention can result in tissue loss and further surgical complications. Documentation is important but is not the priority over timely notification, and adjusting the pouch or applying petroleum gauze does not address the underlying perfusion problem and could delay definitive care.

A nurse is assigned to care for a client who just underwent a thyroidectomy. The nurse notes that the client has developed peripheral numbness and tingling, muscle twitching and spasms. With this, the nurse anticipates to administer?

• Thyroid supplements
• Barbiturates
• Antispasmodics
• Intravenous Calcium

Explanation: Answer reason: Post-thyroidectomy numbness/tingling with muscle twitching and spasms strongly suggests hypocalcemia due to inadvertent removal or stunning of the parathyroid glands, causing decreased PTH and neuromuscular irritability (tetany). Immediate treatment for symptomatic hypocalcemia is IV calcium (commonly calcium gluconate) to rapidly stabilize the myocardium and reduce tetanic symptoms. Thyroid hormone replacement addresses hypothyroidism but would not acutely correct neuromuscular excitability. Sedatives or antispasmodics may mask symptoms while delaying definitive correction of the electrolyte complication and do not treat the underlying cause.

A nurse is caring for an older adult client. The nurse should inform the client that straining while defecating can cause which of the following?

• Dilated pupils
• Dysrhythmias
• Diarrhea
• Gastric ulcer

Explanation: Answer reason: This can produce bradycardia, hypotension, syncope, and conduction changes that may precipitate cardiac rhythm disturbances, especially in older adults with underlying cardiac disease. The clinical risk is therefore cardiovascular instability rather than gastrointestinal pathology. The other options do not reflect typical physiologic consequences of a Valsalva/vagal episode.

A female client diagnosed with lung cancer is to have a left lower lobectomy. What increases the client’s risk of developing postoperative pulmonary complications?

• Height is 5 feet, 7 inches (170.2 cm) and weight is 110 lb (49.9 kg).
• The client tends to keep her real feelings to herself.
• She ambulates and can climb one flight of stairs without dyspnea.
• The client is 58 years of age.

Explanation: Answer reason: Height is 5 feet, 7 inches (170.2 cm) and weight is 110 lb (49.9 kg). Poor nutritional status/low body weight decreases protein reserves and immune function, which impairs wound healing and the ability to clear secretions after thoracic surgery. After a lobectomy, effective cough, respiratory muscle strength, and tissue repair are essential to prevent atelectasis and pneumonia; underweight clients are at higher risk for these complications. By contrast, being able to climb a flight of stairs without dyspnea suggests adequate functional reserve and lowers pulmonary risk. Age 58 alone is not a major standalone risk factor compared with malnutrition, and emotional reserve does not directly increase physiologic pulmonary complication risk.

A nurse is caring for a client diagnosed with an unstable spinal cord injury at the T-7 level. Which intervention should take priority during the planning of care?

• Increase caloric intake to aid healing
• Use skin care products designed for use with incontinence
• Place client on a pressure-reducing support surface
• Increase fluid intake to prevent dehydration

Explanation: Answer reason: A pressure-reducing surface is a priority preventive measure because it continuously decreases interface pressure when turning/repositioning may be limited by spinal precautions. Calorie and fluid increases support recovery but do not address the most imminent, preventable complication arising from restricted mobility. Incontinence skin products are helpful, but pressure relief is the primary driver of early pressure-injury prevention in this context.

While working on a pediatric floor, your 2-year old patients begins experiencing epistaxis. Place the appropriate priority nursing actions in the correct sequence?

• Help the child to sit up and lean forward
• Apply pressure to the nose for at least 10 minutes
• Apply ice to the bridge of the nose
• Keep the child calm and quiet
• If still bleeding, Insert cotton into each nostril

Explanation: Answer reason: Upright positioning with a forward lean promotes drainage out of the nares rather than into the pharynx, decreasing gagging, vomiting, and airway compromise in a toddler. After positioning, continuous firm pressure to the soft part of the nose for at least 10 minutes is the key hemostatic measure; ice is only adjunctive vasoconstriction. Packing with cotton is not an initial nursing priority in a young child and can increase mucosal trauma or pose a choking/aspiration risk if dislodged.

The nurse is talking with a client who has diabetes mellitus (type 1) and is receiving prescribed insulin via an infusion pump. Which of the following statements by the client would require follow-up?

• "I need a bolus dose of insulin prior to a meal."
• "I should refill the pump with short-duration insulin."
• "I can decrease blood glucose monitoring to twice daily."
• "I will change the infusion needle every 2 to 3 days."

Explanation: Answer reason: " Insulin pump therapy uses rapid/short-acting insulin with continuous basal delivery, so interruption or misdosing can quickly cause significant hyperglycemia and even diabetic ketoacidosis. Safe self-management requires frequent glucose checks (often before meals/bedtime and as needed, or continuous monitoring) to guide boluses and detect infusion-set failure early. Reducing monitoring to only twice daily increases the risk of unrecognized hypo/hyperglycemia and delayed response to pump malfunction. In contrast, taking a pre-meal bolus and changing the infusion set every 2–3 days are standard pump practices.

Your elderly patient chokes whenever she is given oral fluids. You should?

• Provide thickened fluids and request a swallowing study
• Push oral fluids and request an occupational therapy consult
• Request a physical therapy consult
• Notify the physician

Explanation: Answer reason: Thickened liquids often improve bolus control and decrease the chance of aspiration compared with thin liquids. A formal swallowing study (typically by speech-language pathology) identifies the safest consistencies and techniques for oral intake and guides diet modifications. “Push oral fluids” increases aspiration risk, and PT/OT consults do not directly assess swallowing safety in the moment.

The nurse provides care for four clients on a medical surgical unit. The nurse knows that which client is at risk for wound dehiscence and evisceration?

• A client diagnosed with Parkinson disease who is 5 feet 8 inches (172.7 cm) tall, weighs 150 lb (68 kg), and had a stereotactic pallidotomy two days ago.
• A client diagnosed with type 2 diabetes mellitus who is 5 feet 5 inches (165.1 cm) tall, weighs 195 lb (88.5 kg), and had an appendectomy one day ago.
• A client with history of mitral stenosis who is 5 feet 2 inches (157.5 cm) tall, weighs 130 lb (60 kg), and had open-heart surgery for mitral valve reconstruction three days ago.
• A client with a fractured left femur who is 6 feet 1 inch (185.4 cm) tall, weighs 170 lb (77.1 kg), and had open reduction and internal fixation surgery four days ago.

Explanation: Answer reason: A client diagnosed with type 2 diabetes mellitus who is 5 feet 5 inches (165.1 cm) tall, weighs 195 lb (88.5 kg), and had an appendectomy one day ago. Dehiscence/evisceration risk rises when wound healing is impaired and when abdominal incisions are exposed to increased intra-abdominal pressure early after surgery. Diabetes and obesity both reduce tissue perfusion and collagen synthesis and increase infection risk, making early postoperative abdominal wounds particularly vulnerable. Post-op day 1 after an appendectomy is a high-risk time because the wound has minimal tensile strength and any coughing/straining can stress the incision. By contrast, the neurosurgical procedure is not a large abdominal incision, and orthopedic/closed incisions generally carry a lower evisceration risk than fresh abdominal surgery with impaired healing factors.

The nurse is caring for a client who had an orthopedic injury of the leg that required surgery and the application of a cast. Postoperatively, which nursing assessment is of highest priority to assure client safety?

• Monitoring for heel breakdown
• Monitoring for bladder distention
• Monitoring for extremity shortening
• Monitoring for blanching ability of toe nail beds

Explanation: Answer reason: Checking capillary refill via nail-bed blanching is a rapid indicator of distal perfusion and helps detect early compartment syndrome or a cast that is too tight. Delayed refill or poor blanching response signals impaired arterial flow requiring urgent intervention to prevent ischemia and permanent tissue damage. Heel breakdown is important but develops over time; bladder distention is not specific to the casted extremity. Extremity shortening relates more to alignment/traction concerns and is less acute than perfusion assessment for immediate safety.

The nurse is measuring the chest tube drainage of a patient who had open heart surgery 4 hours ago. Which of the following is the MAXIMUM hourly amount of chest tube drainage is expected in this timeframe?

• 100 ml
• 200 ml
• 300 ml
• 400 ml

Explanation: Answer reason: A commonly used upper expected threshold in the first several postoperative hours is about 200 mL per hour; beyond this, the nurse should notify the surgeon and anticipate evaluation for ongoing bleeding/coagulopathy. This level aligns with normal immediate post-op oozing from surgical sites while still allowing timely detection of abnormal blood loss. Lower values may occur but are not the maximum expected, while substantially higher amounts raise concern for complications rather than expected findings.

Which newborn infant would warrant immediate intervention by the nursery nurse?

• The 1-hour-old newborn who has abundant lanugo.
• The 6-hour-old newborn whose respirations are 52.
• The 12-hour-old newborn who is turning red and crying.
• The 24-hour-old newborn who has not passed meconium.

Explanation: Answer reason: Failure to pass meconium within the first 24 hours is abnormal and can indicate bowel obstruction or other gastrointestinal pathology that can rapidly become serious. This finding warrants prompt assessment of abdominal distention, feeding intolerance, vomiting (especially bilious), and patency of the anus, and escalation to the provider for further evaluation. In contrast, abundant lanugo is a normal newborn finding, respirations of 52/min are within the expected newborn range (about 30–60/min) when unlabored, and turning red while crying can be a normal response without signs of respiratory distress. Prioritizing early detection of obstruction prevents complications such as dehydration, electrolyte imbalance, and perforation.

The nurse is caring for a client with end-stage liver disease who was admitted for bleeding esophageal varices. The bleeding varices were banded successfully, but the client declined having a transjugular intrahepatic portal-systemic shunt (TIPS) procedure and opted for do not resuscitate (DNR) status. Which topic is most important for the nurse to discuss with the client and family at discharge?

• Complete abstinence from alcohol
• Proper use of medications including lactulose
• The importance of calling the healthcare provider (HCP) immediately if bleeding recurs
• The purpose and use of the DNR bracelet

Explanation: Answer reason: Promptly contacting the HCP/emergency services with any hematemesis, melena, dizziness, or syncope enables rapid stabilization and definitive management before decompensation occurs. Abstinence from alcohol and correct medication use are important long-term measures but do not address the immediate high-risk post-discharge emergency. A DNR order guides actions during cardiopulmonary arrest and does not replace the need to seek emergent care for potentially reversible bleeding.

The nurse is caring for a client diagnosed with type 1 diabetes mellitus. Because the client is at risk for hypoglycemia, which instructions should the nurse teach the client to follow?

• Keep glucose tablets.
• Monitor the urine for acetone.
• Report any feelings of drowsiness.
• Omit the evening dose of NPH insulin if the client has been exercising.

Explanation: Answer reason: Hypoglycemia requires immediate access to a fast-acting carbohydrate to rapidly raise blood glucose and prevent progression to seizure or loss of consciousness. Glucose tablets provide a measured dose of simple sugar that can be taken quickly at the first symptoms, aligning with standard self-management teaching for type 1 diabetes. Urine acetone monitoring is aimed at detecting ketosis/DKA from hyperglycemia rather than preventing or treating hypoglycemia. Omitting scheduled intermediate-acting insulin after exercise is unsafe without provider guidance; exercise generally requires planned carbohydrate intake and/or individualized dose adjustment to avoid wide glucose swings.

The nurse provides a list of instructions to a client being discharged to home with a peripherally inserted central catheter (PICC). The nurse determines that the client needs further instructions if the client made which statement?

• I need to wear a MedicAlert tag or bracelet.
• I need to restrict my activity while this catheter is in place.
• I need to keep the insertion site protected when in the shower or bath.
• I need to check the markings on the catheter each time the dressing is changed.

Explanation: Answer reason: PICC teaching emphasizes preventing infection, dislodgement, and catheter damage while allowing normal daily activity within safe limits. Clients are generally encouraged to continue usual activities, avoiding heavy lifting, repetitive vigorous arm motions, or contact sports that could kink or pull the line, rather than broadly restricting all activity. Protecting the site from water exposure and checking external catheter length/markings help detect dislodgement and reduce contamination risk. Wearing a medical alert identifier is appropriate because it informs providers of central venous access in emergencies and can prevent unsafe procedures in that arm.

A hospitalized client is scheduled for a percutaneous kidney biopsy at 10 AM. At 8 AM, the nurse reviews the client's vital signs and most current serum laboratory results. Which finding is most important to report to the health care provider (HCP)?

• Blood pressure of 180/100 mm Hg
• Creatinine of 2 mg/dL (176.8 µmol/L)
• Hemoglobin of 9.8 g/dL (98 g/L)
• Platelet count of 120,000/mm3 (120 x 10^9/L)

Explanation: Answer reason: This reading is in the severe range and would typically require treatment and possible delay of the procedure until better controlled. While creatinine may be elevated due to underlying renal disease (often the reason for biopsy), it does not by itself create an immediate procedural safety contraindication. Mild anemia and a platelet count of 120,000/mm3 are concerning but are generally less urgent than severe hypertension in predicting acute bleeding complications for this procedure.

The nurse is monitoring a 3-year-old child for signs and symptoms of increased intracranial pressure (ICP) after a craniotomy. The nurse plans to monitor for which early sign or symptom of increased ICP?

• Vomiting
• Bulging anterior fontanel
• Increasing head circumference
• Complaints of a frontal headache

Explanation: Answer reason: It can occur before late findings such as widening pulse pressure, bradycardia, or abnormal respirations. In a 3-year-old, a bulging anterior fontanel and increasing head circumference are unlikely because the fontanels are typically closed and cranial sutures are fused enough that head size does not rapidly expand. Headache can occur, but young children may not reliably localize or verbalize it, whereas vomiting is more observable and clinically actionable as an early change.

The nurse is caring for a client immediately after a paracentesis. It is MOST important for the nurse to ask which of the following questions?

• Do your clothes still feel tight?
• Do you need to void?
• Are you feeling dizzy?
• Do you have any pain?

Explanation: Answer reason: Large-volume paracentesis can cause acute intravascular volume shifts with hypotension, making early detection of hemodynamic instability the priority. Asking about dizziness quickly screens for symptomatic hypotension that may require immediate vital-sign assessment, positioning, and possible fluid/albumin support per protocol. Pain can occur, but severe post-procedure pain is less common and typically follows initial stability checks. “Clothes still feel tight” is a delayed, non-urgent assessment of ascites relief, and urinary urgency is not a primary immediate post-paracentesis safety concern.

The nurse is caring for a postoperative client who has just returned from the postanesthesia care unit after having nasal surgery. What priority action is essential for the nurse to perform?

• Assessing how often the client swallows
• Checking vital signs per agency protocol
• Viewing the external packing for bleeding
• Determining if the client can breathe through the unaffected nostril

Explanation: Answer reason: This complication can rapidly threaten the airway and lead to aspiration, hypovolemia, or shock, so it warrants immediate focused assessment on return from PACU. External packing can appear minimally soiled even when significant internal bleeding is occurring, making it less reliable as a first priority. Vital signs are important but can lag behind early occult bleeding, so targeted assessment for concealed hemorrhage is the essential immediate action.

A client has just undergone endoscopy. Which is the essential postprocedure nursing intervention?

• Keep the client on clear liquid diet for 24 hours.
• Assist the client to gargle with a local anesthetic.
• Check the gag reflex before giving oral foods or fluids.
• Maintain the client with the head of the bed elevated 90 degrees.

Explanation: Answer reason: Endoscopy commonly involves topical pharyngeal anesthesia and sedation, which temporarily depress protective airway reflexes. The key immediate risk post-procedure is aspiration if oral intake is started before the swallow and gag reflexes return. Verifying the gag reflex (and ability to swallow) provides direct evidence that the airway is protected before offering food or fluids. Clear liquids for 24 hours is unnecessary for most routine upper endoscopies, and positioning alone does not address the core aspiration risk.

Before administering a nasogastric feeding to a preterm infant, the nurse aspirates residual fluid from the stomach. Place the following actions in order?

• Position the patient with his head slightly elevated.
• Begin the prescribed nasogastric feeding.
• Measure the aspirate.
• Return the aspirate and subtract the amount of the aspirate from the feeding

Explanation: Answer reason: Aspiration prevention is the priority when initiating or resuming enteral feedings, especially in preterm infants who have immature airway-protective reflexes. Elevating the head before handling residuals and starting the feed reduces reflux and the risk of aspiration during the procedure. After positioning, the nurse measures the residual to assess gastric emptying and feeding tolerance, then typically returns the aspirate to avoid fluid/electrolyte loss and adjusts the feeding volume accordingly. Starting the feeding is performed only after these safety checks and volume adjustments are completed.

Which observation of an 8-pound, 4-ounce neonate, if made by an RN, would require an intervention?

• The neonate’s respirations are 36, shallow, and irregular in rate, rhythm, and depth.
• The neonate’s axillary temperature is 96.2°F (35.6°C).
• Rapid pulsations are visible in the fifth intercostal space, left midclavicular line.
• There is asynchronous spontaneous movement of the infant’s extremities.

Explanation: Answer reason: The neonate’s axillary temperature is 96.2°F (35.6°C). Newborns are prone to heat loss and should be maintained in a neutral thermal environment; an axillary temperature below about 97.7°F (36.5°C) indicates hypothermia that requires nursing action. Hypothermia increases oxygen consumption and can precipitate hypoglycemia, metabolic acidosis, and respiratory distress, so warming measures and reassessment are needed promptly. By contrast, periodic breathing with mild irregularity and a rate in the normal range for a term neonate can be a normal finding when there are no signs of distress. Visible apical impulse at the left 5th intercostal space and asymmetric extremity movements can be normal newborn variants depending on overall assessment.

Which of the following clients is at greatest risk for impaired vascular perfusion?

• An 80-year-old female with a history of alcoholism
• A 75-year-old male with a history of radon gas exposure
• A 59-year-old male with a history of smoking cigarettes
• A 60-year-old male with a diagnosis of hypertension

Explanation: Answer reason: Chronic elevated arterial pressure accelerates endothelial injury and atherosclerosis, increasing the likelihood of impaired tissue and organ blood flow. It also promotes arterial stiffness and left ventricular hypertrophy, which can reduce effective perfusion during stress or acute illness. This makes reduced perfusion complications (e.g., PAD, stroke, renal impairment, coronary ischemia) more directly and broadly likely than the other listed histories. Smoking is a major risk factor too, but hypertension is a direct hemodynamic driver of impaired perfusion across multiple vascular beds and is a common proximate contributor to perfusion-related complications.

The nurse monitors for which acid-base imbalance in the client who has received six units of packed red blood cells in the past 6 hours secondary to blood loss in surgery?

• Metabolic alkalosis
• Metabolic acidosis
• Respiratory alkalosis
• Respiratory acidosis

Explanation: Answer reason: Massive/rapid transfusion in the setting of ongoing hemorrhage can contribute to decreased tissue perfusion and lactic acid production, creating a metabolic acid load. In addition, large-volume transfusion and shock physiology commonly lead to acidemia until perfusion and ventilation are stabilized. This makes an acidosis of metabolic origin the key imbalance to monitor with ABGs and lactate. Respiratory disorders would be driven primarily by hypoventilation or hyperventilation rather than the perfusion and transfusion-related metabolic changes seen here.

A 2-year-old child who has abdominal pain is diagnosed with intussusception. A hydrostatic reduction has been performed. Which finding should be reported immediately before surgery proceeds?

• Palpable sausage-shaped abdominal mass
• Passage of normal brown stool
• Passage of currant jelly-like stools
• Frequent nausea and vomiting

Explanation: Answer reason: This is a key change in status that can alter the plan of care because successful nonoperative reduction can make immediate surgery unnecessary. The nurse should urgently communicate this finding so the team can reassess for ongoing symptoms and confirm reduction rather than proceeding automatically to an operative intervention. In contrast, findings like currant jelly stools or a sausage-shaped mass are classic for active intussusception and do not by themselves signal resolution.

A client who has had a hemiglossectomy and radical right neck dissection arrives in the post anesthesia care unit with two portable drainage catheters in the area of the incision which are attached to Hemovacs. Six hours later one Hemovac accumulates 180 mL of serosanguineous drainage. The priority nursing intervention should be to?

• Turn the client on the right side
• Chart the output as it is expected
• Notify the physician immediately
• Empty the container and reestablish negative pressure

Explanation: Answer reason: A drainage volume like 180 mL over 6 hours can be plausible after extensive head/neck surgery, but the immediate nursing action is to ensure the device is functioning properly by emptying it and recompressing to restore suction. This intervention directly reduces the risk of complications from inadequate drainage while allowing continued accurate monitoring of output. Simply documenting as expected does not address the need to keep the system therapeutic, and notifying the provider is typically reserved for concerning trends (e.g., rapidly increasing bright-red output, hemodynamic instability, or airway compromise).

A 73-year-old patient with chronic atrial fibrillation develops sudden severe pain, pulselessness, pallor, and coolness in the right leg. The nurse should notify the health care provider and immediately?

• Apply a compression stocking to the leg.
• Elevate the leg above the level of the heart.
• Assist the patient in gently exercising the leg.
• Keep the patient in bed in the supine position.

Explanation: Answer reason: This presentation reflects acute arterial occlusion (acute limb ischemia), a time-critical complication in atrial fibrillation due to embolization. Immediate nursing priorities are to prevent further compromise of arterial perfusion, minimize oxygen demand of the limb, and avoid actions that could dislodge or worsen the obstruction while urgent definitive treatment is arranged. Bedrest with the limb kept neutral supports perfusion assessment and avoids provoking pain or increasing metabolic demand. Elevation, compression, or exercise can further reduce arterial flow or increase tissue demand, accelerating ischemic injury.

The nurse is caring for a patient who has been receiving warfarin (Coumadin) and digoxin (Lanoxin) as treatment for atrial fibrillation. Because the warfarin has been discontinued before surgery, the nurse should diligently assess the patient for which complication early in the postoperative period until the medication is resumed?

• Decreased cardiac output
• Increased blood pressure
• Cerebral or pulmonary emboli
• Excessive bleeding from incision or IV sites

Explanation: Answer reason: Warfarin is given in atrial fibrillation to prevent thrombus formation and systemic embolization, so stopping it temporarily increases the risk of thromboembolic events. Early postoperative hypercoagulability and relative immobility further raise the chance of clot formation while anticoagulation is held. Therefore, the nurse should closely monitor for new neurologic deficits suggestive of stroke and for acute respiratory symptoms consistent with pulmonary embolism. Excessive bleeding is less likely specifically because the anticoagulant has been discontinued preoperatively rather than continued.

In teaching clients at risk for bradydysrhythmias, what information does the nurse include?

• Avoid potassium-containing foods.
• Stop smoking and avoid caffeine.
• Take nitroglycerin for a slow heartbeat.
• Use a stool softener.

Explanation: Answer reason: Bradydysrhythmias can be triggered or worsened by increased vagal tone, which slows SA/AV node conduction. Straining with bowel movements (Valsalva maneuver) increases intrathoracic pressure and vagal stimulation, potentially precipitating significant bradycardia, syncope, or heart block in at-risk clients. Teaching bowel regimen measures to avoid straining is a practical prevention strategy, especially in older adults or those with conduction disease. In contrast, avoiding potassium is not a general prevention measure for bradycardia, and nitroglycerin treats angina and can cause hypotension rather than correcting slow heart rate.

A nurse cares for a client who is recovering from a bronchoscopy. Which action does the nurse perform?

• Confirm the return of the client's gag reflex.
• Position the client in the lateral recumbent position.
• Encourage rapid and deep breaths.
• Assist with early ambulation.

Explanation: Answer reason: After bronchoscopy, local anesthetic and sedation can depress protective airway reflexes, creating a high aspiration risk. The priority nursing action is to assess for the return of swallowing and gag reflexes before allowing oral intake or removing NPO restrictions. This directly prevents aspiration and subsequent respiratory compromise, which is a common post-procedure complication. Options like deep rapid breathing or early ambulation do not address the immediate airway protection priority and could be inappropriate if the client is still sedated.

A nurse in the postpartum unit is caring for a client who has just delivered a newborn infant following a pregnancy with placenta previa. The nurse reviews the plan of care and prepares to monitor the client for which of the following risks associated with placenta previa?

• Infection
• Chronic hypertension
• Hemorrhage
• Disseminated intravascular coagulation

Explanation: Answer reason: Postpartum, the client is at high risk for ongoing or delayed hemorrhage because the lower uterine segment contracts less effectively and placental implantation in that area predisposes to continued blood loss. Monitoring focuses on uterine tone, lochia amount, vital signs, and signs of hypovolemia to detect deterioration early. Chronic hypertension is more associated with placental abruption rather than previa, and while severe bleeding can lead to coagulopathy, the primary anticipated complication to monitor for is major bleeding.

The clinic nurse is listening to voicemail messages in the office. Which client should the nurse call back first?

• Client started on capsaicin cream 2 days ago reports sudden burning in the eyes
• Client started on carbidopa-levodopa a day ago reports dizziness on standing
• Client started on hydroxyzine 3 days ago reports urinary difficulty and hesitancy
• Client started on phenytoin a week ago reports blistered lesions on the face and trunk

Explanation: Answer reason: The timing (within the first weeks) and description (blistered lesions involving face/trunk) are red-flag findings that must be prioritized over expected or non-life-threatening side effects. By comparison, orthostatic dizziness with newly started carbidopa-levodopa is a common adverse effect that can often be managed with safety teaching and dose-timing adjustments. Eye burning from accidental capsaicin transfer and urinary hesitancy from hydroxyzine’s anticholinergic effects are concerning but typically less emergent than a suspected life-threatening drug reaction.

The nurse has received report for a term newborn after a vaginal birth. Maternal history includes diagnosis of gestational diabetes at 25 weeks gestation and poorly controlled blood glucose during pregnancy. When assessing the newborn, which finding should the nurse most likely expect?

• Delayed meconium passage
• Elevated hematocrit level
• Shrill cry and frequent yawning
• Smooth philtrum and thin upper lip

Explanation: Answer reason: Chronic hypoxemia stimulates erythropoietin production, leading to polycythemia, which is reflected as an elevated hematocrit. This is a common expected assessment/lab finding in these newborns along with risks like hypoglycemia and hyperbilirubinemia. In contrast, delayed meconium passage is more classically associated with conditions like Hirschsprung disease or hypothyroidism rather than maternal diabetes. The fetal alcohol syndrome features listed (smooth philtrum, thin upper lip) are unrelated to gestational diabetes.

The nurse in the ICU notes bleeding from the client's transparent dressing over her peripheral intravenous site, gum bleeding, and frank blood in the urine. The client was originally admitted for sepsis. What should be the nurse's immediate next action?

• Assess the client's hemoglobin and hematocrit level.
• Check the client's oxygen saturation.
• Apply pressure to the intravenous site.
• Call the physician.

Explanation: Answer reason: Active bleeding requires immediate measures to reduce blood loss using the least invasive, fastest intervention. Direct pressure at a peripheral IV site is an immediate nursing action that can promptly control external bleeding while the nurse continues assessment for systemic bleeding (e.g., possible DIC in sepsis). Laboratory evaluation such as hemoglobin/hematocrit may be indicated, but it does not stop ongoing blood loss and is not the first step. Notifying the provider is important once initial stabilization measures are underway and critical findings are communicated.

Which client is at highest risk for development of pressure ulcers?

• A 65 year old female client scheduled for an elective hysterectomy
• A 55 year old male client who experienced a heart attack with an order for bed rest
• An obese, 70 year old female client diagnosed with hyperglycemic hyperosmolar non-ketosis
• An 80 year old, thin, male client with low albumin, who is confused to person, place and time

Explanation: Answer reason: Pressure injuries are most strongly driven by immobility/unrelieved pressure plus poor tissue tolerance from malnutrition and decreased perfusion. Advanced age and low albumin indicate poor nutritional reserves and impaired wound healing, while being thin reduces natural padding over bony prominences. Confusion increases risk because the client may not perceive discomfort, may not reposition, and may be unable to follow turning/skin-protection instructions. By comparison, bed rest after MI increases risk, but it lacks the additional high-risk factors of severe malnutrition and cognitive impairment present here.

Packed red blood cells have been prescribed for a female client with a hemoglobin level of 7.6g/dL (76mmol/L) and a hematocrit level of 30% (0.30). The nurse takes the client's temperature before hanging the blood transfusion and records 100.6°F (38.1°C) orally. Which action should the nurse take?

• Begin the transfusion as prescribed.
• Administer an antihistamine and begin the transfusion.
• Delay hanging the blood and notify the health care provider (HCP).
• Administer 2 tablets of acetaminophen and begin the transfusion.

Explanation: Answer reason: A key transfusion safety principle is to obtain and evaluate baseline vital signs; a preexisting fever can indicate active infection or another process and would make it difficult to distinguish a new febrile hemolytic/nonhemolytic transfusion reaction once blood is started. With an oral temperature of 38.1°C, the safest nursing action is to hold the blood and report the finding so the prescriber can determine whether to postpone transfusion and/or evaluate and treat the fever first. Giving acetaminophen or an antihistamine to proceed can mask early reaction signs and delays recognition of potentially life-threatening complications. Although the client is anemic, transfusion urgency does not override the need to clarify an abnormal baseline assessment that increases risk during administration.

The nurse is caring for a child diagnosed with Reye’s syndrome. The nurse monitors for manifestations of which condition associated with this syndrome?

• Protein in the urine
• Symptoms of hyperglycemia
• Increased intracranial pressure
• A history of a staphylococcus infection

Explanation: Answer reason: Cerebral edema leads to rising intracranial pressure, so the nurse must closely monitor for changes in level of consciousness, vomiting, seizures, and abnormal posturing. This directly reflects the syndrome’s hallmark risk of rapid neurologic compromise rather than a renal manifestation. Hyperglycemia is not the classic expected finding; hypoglycemia is more likely with severe liver dysfunction in children.

The nurse is reviewing the labs of a child who has recently had oral surgery. Which of the following lab results should the nurse pay the closest attention to?

• BUN level
• Prothrombin time
• Creatinine level
• Viral load

Explanation: Answer reason: Postoperative oral surgery patients are at meaningful risk for bleeding because the mouth is highly vascular and clots can be disrupted by speaking, suctioning, or chewing. A prolonged coagulation study signals impaired hemostasis and predicts postoperative hemorrhage, which is the most immediate safety threat among the listed labs. Monitoring coagulation also guides whether additional evaluation or interventions (e.g., reviewing anticoagulant exposure, liver function, vitamin K status) are needed. BUN and creatinine relate to renal function and medication clearance but are less directly tied to acute post-op oral bleeding risk, and viral load does not address an immediate postoperative complication in this context.

The nurse is obtaining a urine sample from a client with an indwelling Foley catheter. To prevent bladder distention and possible subsequent hydronephrosis, what action should the nurse take?

• Angle the needle toward the drainage bag.
• Use a small-gauge needle to aspirate the sample.
• Release the clamp immediately after the sample is obtained.
• Clamp the tubing 3 inches below the catheter connection point.

Explanation: Answer reason: Maintaining continuous, unobstructed urinary drainage is the key principle to prevent urine backflow, bladder overdistention, and upstream pressure that can contribute to hydronephrosis. Clamping is used briefly only to allow fresh urine to collect in the tubing for a sterile specimen. Once enough urine is obtained, the clamp must be released right away to re-establish free drainage and minimize urinary retention. Prolonged or unnecessary clamping is the main unsafe step in this process, whereas needle size or insertion angle does not address the complication of obstruction.

A client who has had a brain attack (stroke) is being managed on the medical nursing unit. At 8:00 AM, the client was awake and alert with vital signs of temperature 98° F orally, pulse 80 beats/min, respirations 18 breaths/min, and blood pressure 138/80 mm Hg. At noon, the client is now confused and arousable only to tactile stimuli, and vital signs are temperature 99° F orally, pulse 62 beats/min, respirations 20 breaths/min, and blood pressure 166/72 mm Hg. The nurse should take which action?

• Call the physician.
• Reorient the client.
• Administer an antihypertensive PRN.
• Retake the vital signs.

Explanation: Answer reason: A sudden decline in level of consciousness with a rising blood pressure and relative bradycardia after a stroke suggests neurologic deterioration and possible increased intracranial pressure or hemorrhagic conversion, which is a time-sensitive complication. This change is not an expected finding and requires urgent provider notification for rapid evaluation and potential imaging/therapy. Retaking vital signs may confirm numbers but must not delay escalation when there is a clear acute change in neurologic status. Reorientation is inappropriate for a markedly decreased responsiveness, and giving PRN antihypertensive could reduce cerebral perfusion without a specific order/parameters in the context of evolving neurologic injury.

The healthcare provider is assisting during the insertion of a pulmonary artery catheter. Which of these, if assessed in the patient, would indicate the patient is experiencing a complication from the catheter insertion?

• Inspiration phase is greater than expiration
• Vesicular breath sounds noted on auscultation
• Tracheal deviation from midline
• Diaphragmatic excursion of 3cm

Explanation: Answer reason: Rising intrathoracic pressure shifts mediastinal structures, producing tracheal deviation away from the affected side—an acute, life-threatening complication needing immediate intervention. The other findings listed are compatible with normal respiratory assessment (vesicular sounds, typical I:E pattern) or a nonspecific/near-normal excursion value and do not specifically indicate catheter-related thoracic injury. Tracheal deviation is therefore the most concerning assessment suggesting a procedure complication.

A 2-year-old at an outpatient clinic stops breathing and does not have a pulse. CPR is initiated. When the automated external defibrillator (AED) arrives, the nurse notes that it has only adult AED pads. What is the appropriate action at this time?

• Continue CPR without using the automated external defibrillator (AED) until paramedics arrive
• Place one AED pad on the chest and the other on the back
• Place one AED pad on the upper right chest and the other on the lower left side
• Place one AED pad on the upper right chest and dispose of the other

Explanation: Answer reason: If pediatric pads are unavailable, adult pads may be used in small children as long as the pads do not touch each other, because contact can prevent effective shock delivery and risk skin burns. An anterior-posterior (chest/back) placement increases pad separation on a small chest and is recommended when standard anterolateral placement would cause overlap. Continuing CPR without using the AED delays definitive therapy, and discarding one pad makes defibrillation impossible.

The nurse is walking through a mall parking lot and witnesses the collapse of a child. The child is not breathing and has a pulse of 50/min. After the nurse calls emergency services and delivers rescue breaths for 2 minutes, the child is still not breathing and is now pale with a pulse of 49/min. What is the nurse's next action?

• Assess the child's airway
• Begin chest compressions
• Continue rescue breathing
• Perform abdominal thrusts

Explanation: Answer reason: After 2 minutes of effective ventilation, the child remains apneic and is now pale with a pulse of 49/min, indicating inadequate circulation despite oxygenation attempts. The appropriate next step is to start chest compressions while continuing ventilations (CPR). Continuing rescue breathing alone is no longer sufficient because the heart rate is below the CPR threshold with clinical signs of poor perfusion.

A client is having a seizure when the nurse enters the room. What should be the most appropriate action of the nurse?

• Note the first area that starts to seize.
• Take note of the time the seizure began and how long it lasted.
• Place pads on the side rails.
• Provide privacy to the client during the seizure.

Explanation: Answer reason: The immediate nursing priority during an active seizure is safety assessment and rapid identification of prolonged seizure activity that may require emergent treatment. Timing the onset and duration is essential to recognize status epilepticus risk and to guide medication decisions and provider notification. Protective measures like padding side rails are important but should ideally be in place beforehand and must not delay monitoring of duration and airway/safety. Documenting the seizure’s progression is useful, but duration is the most critical real-time datum for urgent clinical decisions.

A client admitted after using crack cocaine develops ventricular fibrillation. After determining unresponsiveness, which action should the nurse take next?

• Defibrillate at 200 J.
• Establish IV access.
• Place an oral airway and ventilate.
• Start cardiopulmonary resuscitation (CPR).

Explanation: Answer reason: Ventricular fibrillation is a pulseless, shockable cardiac arrest rhythm, and immediate high-quality chest compressions are the first action after confirming unresponsiveness to maintain coronary and cerebral perfusion. CPR is initiated while the defibrillator is being brought in/charged because any delay in compressions reduces the likelihood of successful defibrillation and ROSC. Defibrillation is the definitive therapy for VF, but it is performed as soon as the defibrillator is ready, not before starting compressions. Establishing IV access or placing an airway are secondary priorities and should not interrupt early compressions and rapid defibrillation in pulseless VF.

A patient whose heart monitor shows sinus tachycardia, rate 132, is apneic and has no palpable pulses. What is the first action that the nurse should take?

• Perform synchronized cardioversion.
• Start cardiopulmonary resuscitation (CPR).
• Administer atropine per agency dysrhythmia protocol.
• Provide supplemental oxygen via non-rebreather mask.

Explanation: Answer reason: In an apneic, pulseless patient, the priority is immediate initiation of the cardiac arrest algorithm to restore circulation and oxygen delivery. A monitor rhythm that appears like sinus tachycardia can still represent pulseless electrical activity, which is treated with high-quality chest compressions and rapid activation of the resuscitation response. Synchronized cardioversion is reserved for unstable tachyarrhythmias with a pulse, not for pulseless arrest. Atropine is for symptomatic bradycardia, and applying a non-rebreather delays definitive life-saving circulation support when there is no pulse.

Within thirty seconds after birth, an unresponsive and limp newborn is placed on the warmer in the "sniffing" position. The nurse clears the airway, dries, and stimulates the newborn. At 1 minute of life, the newborn has shallow, gasping respirations with a heart rate of 62/min. What action should the nurse take?

• Administer epinephrine
• Begin positive pressure ventilation
• Continue stimulating the newborn
• Start chest compressions

Explanation: Answer reason: A heart rate <100/min with gasping or apnea after initial steps requires immediate positive-pressure ventilation to establish effective oxygenation and improve heart rate. Chest compressions are reserved for persistent heart rate <60/min after at least 30 seconds of effective ventilation, so starting compressions now is premature. Epinephrine is indicated only if the heart rate remains <60/min despite effective ventilation and compressions.

A patient presents with signs of anaphylaxis after a bee sting. Which medication should the nurse administer first?

• Antihistamine.
• Epinephrine.
• Corticosteroid.
• Bronchodilator.

Explanation: Answer reason: Anaphylaxis is a life-threatening airway and circulatory emergency requiring immediate reversal of bronchospasm, mucosal edema, and vasodilation. This drug rapidly provides alpha-1 vasoconstriction to raise blood pressure and reduce airway swelling and beta-2 bronchodilation to improve ventilation. Antihistamines and corticosteroids are adjuncts with slower onset and do not promptly correct shock or airway compromise. Bronchodilators can help wheezing but do not treat the underlying vasodilation and edema driving anaphylactic collapse.

A 21-year-old woman in active labor is admitted to the labor suite. An hour later, the membranes rupture spontaneously. The nurse observes a glistening white cord protruding from the vagina. Which of the following actions should the nurse take FIRST?

• Return to the nurses’ station and place an emergency call to the physician.
• Administer oxygen by mask at 10–12 L/min and assess the mother’s vital signs.
• Place a clean towel over the cord and wet it with sterile normal saline.
• Apply manual pressure to the presenting part and have the mother assume a knee-chest position.

Explanation: Answer reason: Umbilical cord prolapse is an obstetric emergency because cord compression rapidly compromises fetal oxygenation. The immediate priority is to relieve pressure off the cord by elevating the presenting part and using a gravity-assisted position (knee-chest) to reduce compression while preparing for urgent delivery. Calling the provider and administering oxygen are important but do not address the immediate cause of fetal hypoxia if the cord remains compressed. Covering the cord with moist sterile gauze helps prevent vasospasm and drying, but it is secondary to immediately relieving compression.

While helping a patient with a chest tube reposition in the bed, the chest tube becomes dislodged. What is your immediate nursing intervention?

• Stay with the patient and monitor their vital signs while another nurse notifies the physician.
• Place a sterile dressing over the site and tape it on three sides and notify the physician.
• Attempt to re-insert the tube.
• Keep the site open to air and notify the physician.

Explanation: Answer reason: A dislodged chest tube creates an open pneumothorax risk, so the priority is to prevent additional air entry into the pleural space while allowing air to escape. A sterile occlusive dressing taped on three sides functions as a flutter valve to minimize inspiratory air ingress and reduce progression to tension physiology. Reinsertion is outside nursing scope and can cause tissue injury and contamination. Simply monitoring or leaving the site open fails to address the immediate life-threatening air leak.

The nurse in the newborn nursery receives a telephone call to prepare for the admission of a neonate born at 43 weeks’ gestation with Apgar scores of 1 and 4. When planning for the admission of this infant which is the nurse’s highest priority?

• Turning on the apnea and cardiorespiratory monitor
• Connecting the resuscitation bag to the oxygen outlet
• Setting up the intravenous line with 5% dextrose in water
• Setting the radiant warmer control temperature at 36.5°C (97.6°F)

Explanation: Answer reason: Preparing functional positive-pressure ventilation equipment is the most time-critical intervention because ventilation is the primary corrective step in neonatal resuscitation and rapidly improves heart rate. Monitoring and warming are important supportive measures, but they do not correct apnea or poor ventilation. Starting an IV with D5W is not the first priority in initial stabilization and may delay life-saving ventilation readiness.

You are working in the emergency department and find out that a tornado has hit the local area. Numerous casualties are being sent to the emergency department. What action should you take at this time?

• Prepare the triage room.
• Obtain additional supplies.
• Activate the agency disaster plan.
• Call in additional staff.

Explanation: Answer reason: Mass-casualty incidents require a coordinated, predefined command structure to rapidly allocate resources, establish triage flow, and maintain safety. Initiating the facility’s disaster plan triggers the incident command system, clarifies roles, opens surge capacity processes, and mobilizes communications and supply chains in the correct sequence. Actions like preparing triage space, getting supplies, or calling staff are important but should be done under the standardized protocol to prevent duplication, missed steps, and unsafe improvisation. The disaster plan also ensures documentation, security, and patient tracking processes are implemented early when volume will quickly overwhelm normal operations.

The medical center encounters a bomb threat. The emergency response team informs the staff that the threat is legitimate and that clients should start being evacuated. Which of the following clients should the nurse begin evacuating FIRST to the safe designated area?

• Ambulatory clients
• Bedridden clients
• ICU clients
• Infant clients

Explanation: Answer reason: Clients who can walk require minimal assistance and can be directed to the designated safe area immediately, quickly reducing the number of individuals at risk. This also frees staff to return promptly to assist clients who need substantial support (e.g., bedridden or ICU clients). Evacuating high-acuity or immobile clients first can bottleneck the process and delay overall movement to safety.

The nurse is caring for a client with unstable angina whose cardiac monitor shows ventricular tachycardia. Which action is appropriate to implement first?

• Defibrillate the client at 200 J.
• Check the client for a pulse.
• Cardiovert the client at 50 J.
• Give the client IV lidocaine.

Explanation: Answer reason: The immediate priority with a monitor rhythm of ventricular tachycardia is to determine whether it is pulseless or perfusing, because management differs drastically. A rapid pulse check confirms whether to proceed with defibrillation/CPR (pulseless VT) versus synchronized cardioversion or antiarrhythmic therapy (VT with a pulse). Acting on the monitor alone risks delivering an inappropriate shock or delaying life-saving CPR. Establishing the patient’s hemodynamic status first is the safest first action.

A patient's cardiac monitor shows a pattern of undulations of varying contours and amplitude with no measurable ECG pattern. The patient is unconscious and pulseless. Which action should the nurse take first?

• Perform immediate defibrillation.
• Give epinephrine (Adrenalin) IV.
• Prepare for endotracheal intubation.
• Give ventilations with a bag-valve-mask device.

Explanation: Answer reason: The described rhythm (chaotic, varying undulations without identifiable complexes) in an unconscious, pulseless patient is ventricular fibrillation, which is a shockable cardiac arrest. The priority intervention is rapid defibrillation to terminate disorganized ventricular activity and allow a perfusing rhythm to return. Epinephrine is given during CPR after initial defibrillation attempts and does not replace early shock for VF/pulseless VT. Airway interventions (BVM or intubation prep) are supportive but should not delay immediate defibrillation in a witnessed/monitored shockable arrest.

The client arrives in the emergency department with a penetrating eye injury from wood chips that occurred while cutting wood. The nurse assesses the eye and notes a piece of wood protruding from the eye. What is the initial nursing action?

• Apply an eye patch.
• Perform visual acuity tests.
• Irrigate the eye with sterile saline.
• Remove the piece of wood using a sterile eye clamp.

Explanation: Answer reason: With a penetrating eye injury and an impaled object, the priority is to prevent further ocular damage by avoiding any pressure or manipulation that could worsen the globe injury. Shielding/protecting the eye is the safest immediate nursing action to stabilize the injury until definitive ophthalmologic management. Irrigation or attempting to remove the object can convert a controlled injury into a catastrophic rupture and increase bleeding or extrusion of intraocular contents. Visual acuity assessment is important, but protection/stabilization takes precedence when an object is visibly protruding and the risk of worsening injury is high.

An 82-year-old man presents to the emergency department after a ground-level fall. The paramedics tell you that the left pupil was fixed and dilated. Upon arrival, the patient's elbows, wrists, and fingers are flexed, and legs extended and rotated inward. What is the most important intervention for this patient?

• Obtain IV access immediately
• Turn patient on his side
• Obtain accurate history from the family
• Take him straight to the CT scan

Explanation: Answer reason: The priority is immediate stabilization of life-threatening neurologic injury using an ABC approach while preparing for definitive management. A fixed, dilated pupil with posturing suggests severe intracranial pathology with impending herniation, and the patient may rapidly decompensate requiring rapid sequence intubation, hyperosmolar therapy, sedation, and vasopressors. Establishing IV access is the fastest enabling intervention to deliver time-critical resuscitative medications and fluids while other actions (airway management, neurosurgical consult, imaging) are being coordinated. Going straight to CT delays stabilization and risks cardiorespiratory collapse en route, and obtaining history is not time-critical in the setting of signs of herniation. Turning the patient on his side may be useful for vomiting/aspiration risk but does not address the immediate need to support resuscitation and prevent secondary brain injury.

A nurse assesses an infant with a heart rate of 50, cyanotic, and apneic. The nurse should initially?

• Start chest compressions.
• Notify the code/rapid response team.
• Deliver rescue breaths.
• Obtain intravenous access.

Explanation: Answer reason: In infants, a heart rate <60/min with signs of poor perfusion despite oxygenation/ventilation indicates the need to begin CPR with compressions because cardiac output is critically inadequate. This infant is apneic and cyanotic with bradycardia (50), which is consistent with impending cardiopulmonary arrest, so compressions should start immediately while ventilation is provided as part of coordinated CPR. Activating the emergency team is important but must not delay immediate life-saving actions at the bedside. Establishing IV access is a later step once effective CPR is underway and additional help/equipment arrives.

After change-of-shift report, which newly admitted patient should the nurse assess first?

• A patient with human immunodeficiency virus (HIV) whose CD4 count is 45 mm3 (45 cells/mcL)
• A patient with acute kidney transplant rejection who has a scheduled dose of prednisone due
• A patient with graft-versus-host disease who has frequent liquid stools
• A patient with hypertension who has angioedema after receiving lisinopril

Explanation: Answer reason: This presentation requires immediate assessment of airway patency, breathing, oxygenation, and readiness for urgent interventions (e.g., stopping the drug, notifying the provider/rapid response, preparing for epinephrine and advanced airway support as ordered). The other patients are high risk but not as immediately life-threatening in the next minutes: severe immunosuppression (CD4 45) needs protective precautions and infection assessment, GVHD diarrhea needs fluid/electrolyte evaluation, and transplant rejection with prednisone due is important but not more urgent than potential airway compromise. Prioritization follows ABCs, making possible airway obstruction the first assessment.

The nurse administers medications to the client diagnosed with bipolar disorder. The client approaches the nurse and begins to throw things. Which action does the nurse take?

• Sits down and asks the client what is bothering the client.
• Gives the client the medications so the client will calm down.
• Admonishes the client and suggests that the client collect self.
• Gets another nurse to assist with the client.

Explanation: Answer reason: Immediate priority in an escalating behavioral emergency is safety for the client, staff, and other patients using the least restrictive, team-based approach. Calling for assistance provides adequate staffing to maintain control of the environment, implement de-escalation and limit-setting, and be prepared for emergency interventions if needed. Trying to sit and explore feelings during active throwing delays containment and increases risk of injury. Offering medications “to calm down” is not appropriate as a first response in an acute unsafe situation and may be refused, while scolding tends to escalate agitation.

The nurse and group of friends are at the lake. Suddenly, someone says, “Look across the lake! It looks like someone might be drowning out there!” What is the nurse’s first action?

• Determine who is the strongest swimmer in the group.
• Direct someone to locate a cell phone and call 911.
• Find a boat, raft, or some type of flotation device.
• Use a pair of binoculars and look across the lake.

Explanation: Answer reason: In a suspected drowning, the priority is rapid activation of the emergency response system so trained rescuers and advanced life support can be dispatched while bystanders initiate safe rescue measures. Delegating a specific person to call 911 immediately reduces delay and allows the nurse to coordinate scene safety and next steps. Entering the water or organizing a swim rescue is high-risk and should not occur before help is activated and safer “reach/throw/row” options are considered. Searching for a flotation device is important, but it should follow immediate EMS activation rather than replacing it as the first action.

A nurse is caring for a client in the coronary care unit. The display on the cardiac monitor indicates ventricular fibrillation. What should the nurse do first?

• Initiate CPR
• Assess the pulse
• Perform defibrillation
• Assess the level of consciousness

Explanation: Answer reason: The immediate priority is to determine whether the patient is pulseless, which distinguishes cardiac arrest (requiring CPR and rapid defibrillation for VF/pulseless VT) from a perfusing rhythm scenario needing different actions. A quick pulse check (along with rapid responsiveness check) confirms the need to activate the arrest response and proceed with compressions/defibrillation. Initiating CPR or defibrillation without confirming pulselessness risks inappropriate treatment if the monitor finding is not matched by the clinical assessment.

While volunteering at a summer camp as the RN on duty, a child playing soccer falls and breaks their arm. It appears to be a compound fracture. Place the following actions in order of nursing priority when dealing with this injury?

• Assess the injury while calling for help
• Apply ice to the area
• Elevate the arm
• Cover the open wound with a clean dressing

Explanation: Answer reason: Early assessment identifies immediate threats such as uncontrolled hemorrhage or compromised circulation that can lead to limb ischemia and shock. After help is mobilized, covering the open wound reduces contamination risk while awaiting immobilization and transport. Ice and elevation are supportive measures to limit swelling and pain but come after life/limb-threatening concerns are addressed.

The nurse performs admission assessments on 4 clients. Which client assessment information is most concerning and needs priority care?

• 17-year-old with suspected meningococcal meningitis who has a fever of 103 F (39.4 C), headache with photophobia and stiff neck
• 36-year-old who is an IV drug user with cellulitis of the arm, a fever of 103.2 F (39.6 C) and foul-smelling drainage from self-injection sites
• 45-year-old with diabetes mellitus and osteomyelitis of the foot who has a fever of 100.9 F (38.3 C) and a serum glucose of 295 mg/dl (16.4 mmol/L)
• 76-year-old with chronic bronchitis who has a fever of 101 F (38.3 C) and a productive cough of thick green mucus

Explanation: Answer reason: 17-year-old with suspected meningococcal meningitis who has a fever of 103 F (39.4 C), headache with photophobia and stiff neck This presentation suggests acute bacterial meningitis with a high risk for rapid deterioration, sepsis, increased intracranial pressure, and airway/hemodynamic compromise. It also demands immediate droplet precautions and urgent diagnostic/therapeutic actions (cultures and prompt antibiotics) to reduce mortality and transmission. Compared with localized skin/soft tissue infection, chronic osteomyelitis with hyperglycemia, or bronchitis with purulent sputum, meningococcal disease is more time-critical and life-threatening. Prioritizing this client aligns with addressing the most unstable, high-acuity condition and preventing spread to others.

You are the permanently assigned nurse in an adult medical-surgical floor. You hear a “Code Pink” over the public address system. You know that a “Code Pink” means an infant abduction, and you have a small role in infant abductions, but you also know that your hospital has fire drills and infant abduction drills every 2 months. Because you are working in the adult medical-surgical area without infants, you?

• Must respond and perform your role in this code.
• Ask the unit secretary to go to the code for you.
• Ignore the code because you are caring for clients.
• Ignore the code because you are not in the nursery.

Explanation: Answer reason: Facility emergency codes require all staff to implement their assigned responsibilities to protect patients and support a coordinated response. An infant abduction alert is a security emergency where roles often include monitoring exits, challenging suspicious persons per policy, and maintaining unit control, even on adult units. Delegating to the unit secretary is inappropriate because the nurse retains accountability and the secretary’s role/training may differ from the code plan. Ignoring the overhead page because of current assignments or unit location delays containment and increases risk, which conflicts with mandated emergency procedures.

A delivery room nurse is caring for a client in labor. The client tells the nurse that she feels that something is coming through the vagina. The nurse performs an assessment and notes the presence of the umbilical cord protruding from the vagina. The nurse should immediately place the client in which position?

• Prone
• Supine
• On the side
• Reverse Trendelenburg's

Explanation: Answer reason: The immediate nursing priority is to relieve cord pressure by using a position that elevates the pelvis and shifts the fetus off the cord with gravity. Knee-chest positioning (client prone with hips elevated) is a standard first action while preparing for urgent delivery and maintaining fetal perfusion. Supine positioning worsens aortocaval and cord compression risk, and reverse Trendelenburg lowers the pelvis, increasing pressure on the cord.

A 60-year-old client wanders away during halftime at a football game and is found 48 hours later sleeping on a park bench, 100 miles from home. The client is brought to the emergency department by the police. The client can state the name and address but has no recollection of the past 2 days. What is the priority nursing action?

• Assess vital signs
• Contact family members
• Encourage the client to recall recent events
• Perform a mental status assessment

Explanation: Answer reason: A client found after 48 hours missing is at high risk for dehydration, hypothermia/heat exposure, intoxication, infection, trauma, or metabolic derangements that can cause acute confusion and amnesia. Checking vital signs is the fastest way to identify immediate instability requiring urgent intervention and guides further assessment (e.g., glucose, oxygenation, temperature management). A focused mental status assessment is important, but it comes after ensuring the client is hemodynamically and respiratorily stable and not experiencing an occult medical emergency.

The home health nurse is assessing a client in their home with suspected carbon monoxide poisoning. The nurse should take which priority action?

• Move the client outdoors
• Notify the primary healthcare provider (PHCP)
• Auscultate the client's lung sounds
• Assess the client's pulse oximetry

Explanation: Answer reason: Carbon monoxide poisoning is a time-critical environmental emergency where the immediate priority is to stop ongoing exposure and restore oxygen delivery. Removing the client to fresh air rapidly reduces further inhalation and is the first step before additional assessment or notifications. Pulse oximetry can appear falsely normal in carbon monoxide poisoning because it cannot reliably distinguish oxyhemoglobin from carboxyhemoglobin, so it must not delay removal from the source. After evacuation, the nurse can activate emergency response/EMS and arrange high-flow oxygen and further evaluation, including carboxyhemoglobin measurement.

The nurse observes that a fire has ignited in the client's room. After removing the client from the room, the nurse should then?

• Activate the fire alarm.
• Extinguish the fire.
• Contact the nursing supervisor.
• Close the door to the client's room.

Explanation: Answer reason: Fire response follows RACE: Rescue, Alarm, Contain, Extinguish/Evacuate. After the client has been rescued, activating the alarm is the next priority to initiate the facility’s emergency response, alert staff, and summon the fire department. Closing the door is an important containment step but comes after ensuring the alarm has been triggered. Attempting to extinguish the fire is only appropriate after the alarm is activated and the fire is small/contained with an appropriate extinguisher and safe exit available.

A client has been defibrillated three times. The nurse observes that the attempts to convert the ventricular fibrillation were unsuccessful. Based on an evaluation of the situation, the nurse anticipates that which of the following actions would be best?

• Performing cardiopulmonary resuscitation (CPR)
• Terminating the resuscitation effort
• Administering sodium bicarbonate intravenously
• Defibrillating three more times at 400 joules

Explanation: Answer reason: After an unsuccessful shock sequence, resuscitation algorithms direct rescuers to resume chest compressions promptly rather than pausing for repeated shocks. Routine sodium bicarbonate is not indicated in VF/pulseless arrest unless specific causes exist (e.g., hyperkalemia, tricyclic overdose, prolonged arrest with severe acidosis). Terminating efforts is inappropriate without meeting clear cessation criteria, and repeatedly escalating shocks without CPR increases no-flow time and worsens outcomes.

A client who was recently discharged from the psychiatric unit telephones the unit to speak to the nurse. The client states that she took her children to the neighbors’ house and has turned on the gas to kill herself. She is home alone and gives the nurse her address. Which of the following actions should the nurse do next?

• Refer the caller to a 24-hour suicide hotline.
• Tell the caller that another nurse will telephone the police.
• Ask the caller whether she telephoned her physician.
• Instruct the caller to telephone her family for help.

Explanation: Answer reason: Imminent suicide with an active method in progress (gas exposure) is a time-critical emergency requiring immediate activation of emergency services for a welfare check and rapid intervention. The nurse should keep the caller engaged on the phone while ensuring 911/police are contacted without delay, using available staff to place the call. Referral to a hotline or advising the client to call family/physician introduces unsafe delay and relies on the suicidal person to take protective action. Immediate emergency response best addresses the acute lethal risk and prioritizes client safety over routine follow-up steps.

A nurse assesses an infant with a heart rate of 50, cyanotic, and apneic. The nurse should initially?

• Start chest compressions.
• Notify the code/rapid response team.
• Deliver rescue breaths.
• Obtain intravenous access.

Explanation: Answer reason: In infants, most cardiac arrests are secondary to respiratory failure, so establishing effective ventilation is the priority when the child is apneic and cyanotic. Providing positive-pressure ventilation with high-quality rescue breaths can correct hypoxemia and may improve bradycardia rapidly. Chest compressions are started when the heart rate remains <60/min despite adequate ventilation and oxygenation rather than as the first step here. Activating the code team and obtaining IV access are important but should not delay immediate airway and breathing support.

The nurse in primary health clinic is caring for a 68-year-old man. History reveals that the client has smoked one pack of cigarette per day for 45 years and drinks two beers per day. He is complaining of a non-productive cough, chest discomfort, and dyspnea. The nurse hears isolated wheezing in the right middle lobe. It would be most important for the nurse to do which of the following?

• CPK-MB
• Echocardiogram
• Chest X-ray
• Guthrie

Explanation: Answer reason: g., lung cancer) or other localized pulmonary pathology, which should be evaluated first with an initial chest imaging study. A chest radiograph is the standard first-line diagnostic test to assess for masses, atelectasis, pneumonia, or other structural changes and guides urgent referral for further imaging (e.g., CT) if abnormal. Cardiac tests like CPK-MB or echocardiogram do not directly address a localized unilateral wheeze pattern and respiratory symptoms without a clear cardiac presentation. New or changing respiratory symptoms in a high-risk smoker warrant prompt pulmonary evaluation to reduce risk of delayed diagnosis.

The nurse teaches a client scheduled for an I.V. pyelogram what to expect when the dye is injected. The nurse knows that the client has correctly understood what was taught when he states that he may experience which of the following sensations when the dye is injected?

• A metallic taste.
• Flushing of the face.
• Cold chills.
• Chest pain.

Explanation: Answer reason: Iodinated contrast used in an IV pyelogram commonly causes a brief sensation of warmth and flushing shortly after injection due to vasodilation and the hyperosmolar effect of the dye. This is an expected, transient response that patients should be taught to anticipate so it is not mistaken for an emergency. In contrast, chest pain is not an expected benign sensation and could signal a serious adverse reaction or cardiopulmonary problem requiring immediate evaluation. Cold chills are less characteristic of routine contrast injection teaching than warmth/flushing.

To evaluate a patient for hypoxia, the physician is most likely to order which laboratory test?

• Red blood cell count.
• Sputum culture.
• Total hemoglobin.
• Arterial blood gas (ABG) analysis.

Explanation: Answer reason: Hypoxia is best evaluated by directly measuring arterial oxygenation and ventilation status. An ABG provides PaO2 and SaO2 (oxygenation) along with PaCO2 and pH, allowing confirmation of hypoxemia and associated acid–base/ventilatory abnormalities. Red blood cell count and total hemoglobin assess oxygen-carrying capacity but do not indicate whether blood is adequately oxygenated in the lungs. Sputum culture targets infectious etiology rather than immediate oxygenation status.

The physician orders a 24-hour urine collection to aid in the diagnosis of Cushing's syndrome. The nurse is most accurate in telling the client that the urine collection will begin when?

• With the client's next voiding
• After the client's next voiding
• After drinking a pitcher of water
• With the first voiding in the morning

Explanation: Answer reason: Starting collection immediately after the next voiding ensures the bladder has been emptied and all urine produced afterward is captured. This prevents overcounting urine produced before the official start time, which would distort total analyte excretion (e.g., urinary free cortisol). A common error is beginning with the next void saved, which includes urine accumulated before the start time and invalidates timing accuracy. Accurate timing and complete collection are critical for reliable diagnostic interpretation in suspected hypercortisolism.

When scheduling a patient for skin testing for allergies, which information is most important for the allergy clinic nurse to include in patient teaching?

• Avoid taking antihistamines before the skin testing.
• Skin testing may be done with an intradermal injection.
• Swelling and itching may occur at the site of the skin testing.
• Patient will need to wait in the clinic for 20 minutes after the testing.

Explanation: Answer reason: Skin allergy testing relies on an immediate histamine-mediated wheal-and-flare response to identify sensitization. Antihistamines blunt this response and can cause false-negative results, making the test invalid and potentially delaying correct diagnosis and treatment. This is higher priority than describing technique or expected local reactions because it directly affects test accuracy and clinical decision-making. While post-test observation addresses safety for systemic reactions, the key pre-test teaching that prevents an unreliable test is medication avoidance.

A nurse is preparing to collect a 24-hour urine specimen from the client. Which of the following is an inaccurate action in collecting the specimen?

• Discarding the urine specimen at the start time
• Asking the client to void, saving the specimen, and noting the start time
• Placing the specimen on ice or refrigerating it
• Asking the client to void at the end of the collection and adding this specimen to the collection

Explanation: Answer reason: Therefore, the client should void at the start time and that first urine is discarded while the time is documented, ensuring the collection reflects exactly the next 24 hours. Keeping the initial void falsely increases the measured total because it includes urine produced before the timed interval. Refrigeration/ice and including the final void at the end time are appropriate because they preserve analytes and complete the timed period.

An echocardiogram, chest x-ray (CXR), and computed axial tomography (CAT) scan are prescribed for a client who has activity intolerance. In which order should the nurse plan to schedule the procedures to meet the needs of this client safely and effectively?

• CAT scan and CXR in the morning, and echocardiogram on the following morning
• CXR and echocardiogram together in the morning, and CAT scan in the afternoon of the same day
• Echocardiogram in the morning, and CXR and CAT scans together in the afternoon of the same day
• CXR in the morning, echocardiogram in the afternoon, and CAT scan in the morning of the following day

Explanation: Answer reason: A chest x-ray and echocardiogram are generally quick, noninvasive, and well-tolerated, making them appropriate to schedule together earlier when the client has the most energy. A CT study can take longer, may require transport and prolonged positioning, and may involve contrast-related monitoring, so placing it later in the day after the shorter tests reduces cumulative exertion while completing all tests within a safe timeframe. Plans that split testing across multiple days increase repeated transfers and disruption without clear benefit for tolerance or safety.

An ultrasound of the gallbladder is scheduled for the client with a suspected diagnosis of cholecystitis. Which should the nurse explain to the client about this test?

• The test is uncomfortable.
• The test requires that the client be NPO.
• The test requires the client to lie still for short intervals.
• The test is preceded by the administration of oral tablets.

Explanation: Answer reason: Fasting is required before gallbladder ultrasound because food intake triggers cholecystokinin-mediated gallbladder contraction, which can empty the gallbladder and obscure stones or wall findings. An adequately distended gallbladder improves visualization of the lumen, wall thickening, pericholecystic fluid, and sonographic Murphy sign used to evaluate cholecystitis. The procedure is noninvasive and typically not painful, so describing it as uncomfortable is misleading. No oral contrast tablets are routinely given for a gallbladder ultrasound; that type of preparation is associated with other biliary imaging studies.

The nurse has taught a client who is scheduled for a colonoscopy. Which of the following statements by the client would require follow up?

• I will not be able to eat or drink anything for 24 hours before the procedure.
• I may experience abdominal cramping after the procedure.
• I will be sedated during the procedure.
• I will be placed in the knee-chest position for the procedure.

Explanation: Answer reason: Colonoscopy preparation typically includes clear liquids the day before and nothing by mouth for a shorter interval before sedation (often 6–8 hours for solids, ~2 hours for clear liquids per anesthesia policy), not a full 24 hours of no intake. Over-restricting intake can worsen dehydration and electrolyte imbalance, especially when combined with bowel prep. The other statements reflect expected teaching: mild cramping/bloating can occur from insufflated air, moderate sedation is commonly used, and positioning is usually left lateral (often with knees flexed) rather than requiring the client to be fully NPO for 24 hours. This statement signals misunderstanding of pre-procedure instructions and should be clarified for safety.

A child presents to the emergency following ingestion of around 20 mL of kerosene oil about 40 minutes back. The child appears stable. Which one of the following measures should be done for the management of the child?

• Gastric lavage
• Oxygen therapy
• Intravenous steroids
• Radiography

Explanation: Answer reason: In a stable child, the key management is observation and assessment for evolving respiratory involvement rather than attempting gastric lavage. A chest radiograph is recommended to detect early pneumonitis (which may be present even with minimal initial symptoms) and to guide ongoing monitoring. Oxygen is supportive only if respiratory symptoms or hypoxemia develop, and steroids have no proven routine benefit in hydrocarbon pneumonitis.

A 60-year-old comes into the emergency department with crushing substernal chest pain that radiates to the shoulder and left arm. The admitting diagnosis is acute myocardial infarction (MI). Admission prescriptions include oxygen by nasal cannula at 4 L/min, complete blood count (CBC), a chest radiograph, a 12-lead electrocardiogram (ECG), and 2 mg of morphine sulfate given IV. The nurse should first?

• Administer the morphine.
• Obtain a 12-lead ECG.
• Obtain the blood work.
• Prescribe the chest radiograph.

Explanation: Answer reason: Time-sensitive diagnosis and reperfusion decisions in suspected MI depend on immediate ECG acquisition to identify STEMI and guide urgent therapies (e.g., cath lab activation). This test should be prioritized before noncritical labs and imaging because delays directly worsen myocardial salvage and outcomes. Analgesia with morphine can be helpful for pain/anxiety but can also mask symptoms and should not precede obtaining the key diagnostic data needed for definitive management. A chest radiograph and CBC are adjuncts for differential/complication assessment and do not drive the initial MI pathway as rapidly as the ECG.

The nurse is monitoring the status of a client's fat emulsion (lipid) infusion and notices that the infusion is 1 hour behind. Which action should the nurse take?

• Adjust the infusion rate to catch up over the next hour.
• Increase the infusion rate to catch up over the next 2 hours.
• Ensure that the fat emulsion infusion rate is infusing at the prescribed rate.
• Adjust the infusion rate to run wide open until the solution is back on time.

Explanation: Answer reason: IV lipid emulsions should be infused at an ordered rate because rapid infusion increases the risk of adverse effects such as fat overload syndrome and metabolic/respiratory complications. When an infusion is behind schedule, the safe first step is to verify the pump settings and assess for causes (e.g., occlusion, infiltration, tubing/pump error) rather than compensating by speeding up delivery. “Catching up” by increasing the rate or running the infusion wide open can deliver an unintended bolus and exceed recommended hourly limits. Maintaining the prescribed rate supports safe, controlled administration and prompts correction of the underlying issue.

The nurse is assessing a client's peripheral intravenous (IV) site after completion of a vancomycin infusion and notes that the area is reddened, warm, painful, and slightly edematous proximal to the insertion point of the IV catheter. At this time, which action by the nurse is best?

• Check for the presence of blood return.
• Remove the IV site and restart at another site.
• Document the findings and continue to monitor the IV site.
• Call the health care provider (HCP) and request that the vancomycin be given orally.

Explanation: Answer reason: The findings (redness, warmth, pain, and edema tracking proximal to the insertion site) are most consistent with phlebitis and/or infiltration related to peripheral IV therapy. The safest immediate nursing action is to stop using the affected vein by discontinuing the catheter, because continuing infusion can worsen tissue injury and inflammation. Restarting at a new site preserves venous access while preventing further damage at the compromised site. Merely checking for blood return or continuing to monitor delays definitive management, and requesting oral vancomycin is not an appropriate first response because it does not address the local IV complication and oral vancomycin is typically reserved for specific indications (e.g., C. difficile colitis).

Which of the following injection should not mixed with dopamine for infusion through a central line?

• Potassium chloride
• Calcium gluconate
• Soda bicarbonate
• Dobutamine

Explanation: Answer reason: Dopamine is unstable in alkaline solutions, and sodium bicarbonate raises pH, which can inactivate the catecholamine and/or cause incompatibility in the line. This can lead to reduced therapeutic effect and potential line occlusion. In contrast, electrolytes like potassium chloride are commonly Y-sited with many fluids when verified compatible and do not have the same strong alkalinizing effect that drives dopamine instability.

A patient with ventricular tachycardia has been ordered to receive IV (intravenous) lidocaine. What does the nurse dilute the lidocaine solution with?

• Normal Saline 0.9%.
• 5% Dextrose in water.
• Normal Saline 0.45%.
• Lactated Ringers.

Explanation: Answer reason: IV lidocaine infusions are prepared in compatible diluents to maintain drug stability and prevent precipitation or loss of potency during administration. Dextrose 5% in water is a standard compatible diluent for lidocaine continuous infusion used for ventricular dysrhythmias. Using an incompatible solution risks reduced therapeutic effect or infusion complications, which is especially unsafe when treating ventricular tachycardia. Normal saline or lactated Ringer’s may be used for many IV drugs, but for lidocaine infusion D5W is the commonly specified compatible diluent in clinical practice and exam references.

The nurse is checking on clients in the unit. Which of these findings indicates that an infusion pump set to deliver a morphine drip basal rate of 10 mL per hour, plus PRN dosages for breakthrough pain, is not functioning correctly?

• The client states: "I just can't get relief from my pain."
• The level of the drug is 100 mL at 9 am and is 50 mL at 12 noon
• The level of the drug is 100 mL at 8 am and is 80 mL at 12 noon
• The client complains of discomfort at the IV insertion site

Explanation: Answer reason: From 8 am to 12 noon is 4 hours, so at 10 mL/hr the pump should infuse about 40 mL (leaving ~60 mL from a 100 mL starting volume), and PRN doses would make the volume decrease even more. A drop of only 20 mL over 4 hours indicates under-infusion or an occlusion/flow problem despite the ordered basal rate. By contrast, the 9 am to 12 noon change from 100 mL to 50 mL (50 mL over 3 hours) could be explained by the basal infusion plus PRN breakthrough doses rather than pump malfunction.

A newborn admitted with pyloric stenosis is lethargic and has poor skin turgor. The health-care provider has prescribed IV fluids of dextrose water with sodium and potassium. The baby's admission potassium level is 3.4 mEq/L. What should the nurse do first?

• Notify the HCP.
• Administer the prescribed fluids.
• Verify that the infant has urinated.
• Have the potassium level redrawn.

Explanation: Answer reason: Potassium should not be administered until adequate renal function is confirmed because impaired urine output can rapidly lead to dangerous hyperkalemia and dysrhythmias. An infant with pyloric stenosis is often dehydrated from vomiting, increasing the risk of oliguria and reduced potassium excretion. The immediate nursing priority before starting fluids containing potassium is to verify urine output (e.g., wet diaper) to ensure the kidneys can clear potassium safely. A potassium of 3.4 mEq/L is only mildly low and does not override the safety check required prior to giving IV potassium.

The nurse reviews prescriptions for assigned adult clients. Which prescription should the nurse question?

• 0.45% sodium chloride (NaCl) solution prescribed for a client with syndrome of inappropriate antidiuretic hormone secretion who has a sodium level of 120 mEq/L (120 mmol/L)
• 0.9% NaCl solution prescribed for a client with gastrointestinal bleeding who has a hemoglobin level of 8.9 g/dL (89 g/L)
• 1,000 mL bolus of 0.9% NaCl solution prescribed for a client with septic shock who has a white blood cell count of 18,000/mm3 (18.0 × 109/L)
• Lactated Ringer's solution prescribed for a male client with hypovolemic shock and a thermal burn who has a hematocrit level of 56% (0.56)

Explanation: Answer reason: 0.45% sodium chloride (NaCl) solution prescribed for a client with syndrome of inappropriate antidiuretic hormone secretion who has a sodium level of 120 mEq/L (120 mmol/L) Severe hyponatremia in SIADH reflects excess free water relative to sodium, so treatment generally requires fluid restriction and, when symptomatic or very low, hypertonic saline to raise serum sodium safely. A hypotonic IV fluid provides additional free water and can further dilute serum sodium, worsening cerebral edema and neurologic risk. In contrast, isotonic crystalloids are appropriate for volume resuscitation in septic shock and hypovolemic burn shock, and isotonic saline can be used to support intravascular volume in GI bleeding while definitive therapy (including blood products as indicated) is arranged. Therefore the hypotonic maintenance fluid order is the one that is unsafe and should be questioned.

The nurse plans to start an IV line on a female client hospitalized with pneumonia. The nurse reviews the electronic medical record for relevant information and learns that the client is right-handed and has a history of a left-sided mastectomy with lymph node removal. Which site is best for the nurse to select for the client's IV line?

• Basilic vein of the left forearm
• Cephalic vein in the right antecubital space
• Median vein of the right forearm
• Radial vein of the left wrist

Explanation: Answer reason: Therefore, the right arm is preferred over the left arm for venipuncture and IV therapy in this client. A forearm site is generally more stable and allows greater mobility than an antecubital site, which is prone to occlusion and infiltration with elbow flexion. Selecting a vein in the right forearm balances safety (avoiding the affected limb) with practicality and lower complication risk compared with the antecubital fossa.

A nurse provides IV fluid resuscitation for a client with infectious colitis and dehydration. The nurse understands what intravenous solution is best for this client?

• Ringer lactate
• 0.9% normal saline
• 5% dextrose in 0.45% normal saline
• 5% dextrose in water

Explanation: Answer reason: Initial IV resuscitation for dehydration from infectious diarrhea should use an isotonic crystalloid to rapidly expand intravascular volume and restore perfusion. This fluid stays primarily in the extracellular space, making it appropriate for acute volume depletion. Dextrose-containing solutions become effectively hypotonic after metabolism and are poor choices for bolus resuscitation because they do not sustain intravascular expansion. A common pitfall is selecting hypotonic maintenance fluids (e.g., dextrose with half-normal saline) too early, which can worsen hyponatremia risk in ongoing GI losses.

The nurse administers an IV antibiotic to a patient receiving TPN via a central venous catheter. What does the nurse do first?

• Check compatibility of antibiotic and TPN.
• Turn TPN off for 30 minutes.
• Flush central line with normal saline.
• Ensure separate IV access route.

Explanation: Answer reason: TPN is a high-risk, hypertonic solution that should run on a dedicated lumen to prevent incompatibility, precipitation, and interruption of critical nutrition/insulin coverage. Before giving an IV antibiotic, the priority safety action is to verify there is a separate IV route (another lumen or peripheral line) so the medication does not mix with TPN in the tubing. Compatibility checks and line flushing are secondary once a safe access plan is confirmed; flushing a lumen used for TPN can also unnecessarily interrupt the infusion and increase line manipulation. Simply turning off TPN for a set time is not a standard first step and can risk glycemic instability without solving the access/compatibility issue.

A nurse discovers that an infusion of peripheral parenteral nutrition (PPN) is empty, and a replacement bag is not yet ready. What should the nurse do next while waiting for the PPN bag?

• Hang an intravenous infusion of 10% dextrose in water.
• Hang an intravenous infusion of normal saline.
• Hang an intravenous infusion of 20% dextrose in water.
• Convert the intravenous infusion to a saline lock.

Explanation: Answer reason: Abrupt interruption of parenteral nutrition can cause hypoglycemia because the patient’s insulin levels may remain elevated after a continuous glucose infusion stops. The safest immediate action is to maintain a dextrose-containing IV at a similar osmolarity appropriate for peripheral access until the next bag is available. Normal saline or a saline lock would not provide glucose and increases risk for symptomatic hypoglycemia. D20W is typically too hypertonic for peripheral infusion and raises risk of phlebitis or vein injury.

A nurse is preparing to administer 2 continuous IV medications concurrently via a 20-gauge IV. What is the nurse's priority action?

• Assess the condition of the IV site
• Check 2 client identifiers before administering medications
• Consult a medication guide for compatibility
• Wash hands prior to administering medications

Explanation: Answer reason: Verifying compatibility (or the need for separate lumens/Y-site restrictions and required flushing) directly addresses the unique hazard created by concurrent infusion through a single peripheral IV. Checking identifiers and hand hygiene are essential safety steps but do not specifically mitigate the immediate risk of mixing two infusions in one line. Assessing the IV site is important, yet even a healthy site does not prevent an incompatibility reaction occurring within the tubing or catheter.

A health care provider has written a prescription to discontinue an intravenous (IV) line. The nurse should obtain which item from the unit supply area for applying pressure to the site after removing the IV catheter?

• Elastic wrap
• Povidone iodine swab
• Adhesive bandage
• Sterile 2 × 2 gauze

Explanation: Answer reason: A sterile gauze pad provides a clean, absorbent surface that allows firm, focused pressure while also protecting the open puncture from contamination. An adhesive bandage is typically applied after bleeding has stopped, but it does not provide adequate pressure during the initial hemostasis phase. Elastic wrap and povidone-iodine swab are not primary tools for immediate direct pressure at a peripheral IV removal site.

Main function of hPL is?

• Maintain corpus luteum
• Decrease insulin sensitivity → gestational diabetes risk
• Relax uterus
• Stimulate labour

Explanation: Answer reason: It induces maternal insulin resistance and increases lipolysis, thereby raising maternal blood glucose availability. This physiologic diabetogenic effect explains the increased risk of gestational diabetes as pregnancy progresses. Maintaining the corpus luteum is primarily mediated by hCG, while uterine relaxation and labor stimulation are more associated with progesterone/relaxin and oxytocin/prostaglandins respectively.

What is the name of the hormone that regulates calcium levels in the body?

• Insulin
• Glucagon
• Parathyroid hormone
• Adrenaline

Explanation: Answer reason: Parathyroid hormone increases serum calcium by stimulating osteoclast-mediated bone resorption (indirectly via osteoblast signaling), increasing renal calcium reabsorption, and activating vitamin D to enhance gut absorption. Insulin and glucagon regulate blood glucose, not calcium. Adrenaline mediates sympathetic “fight-or-flight” responses and does not serve as the main regulator of calcium levels.

What is the name of the hormone that regulates the body's response to stress?

• Insulin
• Glucagon
• Cortisol
• Adrenaline

Explanation: Answer reason: It is released from the adrenal cortex and helps maintain stress adaptation by increasing gluconeogenesis, supporting blood pressure through permissive effects on catecholamines, and modulating inflammation and immune activity. This best matches the concept of “regulating” the body’s response to stress over time. A common distractor is adrenaline, which is more associated with the rapid, short-lived fight-or-flight response from the adrenal medulla rather than ongoing regulation.

What is the main role of the adrenal glands?

• Regulate blood sugar
• Produce stress hormones
• Filter blood
• Digest carbohydrates

Explanation: Answer reason: The adrenal medulla secretes catecholamines (epinephrine and norepinephrine) for acute “fight-or-flight,” while the adrenal cortex produces cortisol that supports stress adaptation, metabolism, and blood pressure maintenance. Blood sugar regulation is primarily governed by pancreatic insulin and glucagon, even though cortisol can influence glucose levels. Filtering blood is a kidney function, and carbohydrate digestion is performed by gastrointestinal enzymes, not adrenal tissue.

The body temperature is maintained by?

• Estrogen
• Oxytocin
• Thyroxin
• Insulin

Explanation: Answer reason: Thyroid hormone increases cellular oxygen consumption and heat production (thermogenesis), supporting normal core temperature. In hypothyroidism, reduced metabolic activity commonly leads to cold intolerance and lower heat generation, illustrating this relationship. The other listed hormones primarily regulate reproductive functions (estrogen, oxytocin) or glucose metabolism (insulin) rather than baseline thermoregulation.

Which disease is characterized by the body's inability to regulate blood sugar (glucose) levels?

• Arthritis
• Asthma
• Diabetes
• Hepatitis

Explanation: Answer reason: Glucose regulation depends primarily on adequate insulin secretion and effective insulin action to maintain normal blood sugar levels. In diabetes mellitus, insulin is deficient (type 1) and/or tissues are resistant to insulin’s effects (type 2), leading to persistent hyperglycemia and impaired glycemic control. This directly matches the stem’s description of inability to regulate blood glucose. Arthritis and asthma are inflammatory conditions of joints and airways, respectively, and do not primarily cause dysregulated blood sugar. Hepatitis affects the liver and can alter metabolism, but it is not defined by primary failure of blood glucose regulation.

Which of the following is a type of endocrine gland that produces insulin and glucagon?

• Thyroid gland
• Adrenal gland
• Pituitary gland
• Pancreas

Explanation: Answer reason: Beta cells release insulin to lower blood glucose by promoting cellular uptake and storage, while alpha cells release glucagon to raise blood glucose via glycogenolysis and gluconeogenesis. The pancreas is a mixed gland, with an exocrine digestive function and an endocrine function specifically responsible for these hormones. In contrast, the thyroid primarily secretes T3/T4 and calcitonin, and the adrenal and pituitary glands produce different hormone sets not responsible for insulin/glucagon secretion.

The body temperature is maintain by the ...?

• Estrogen
• Oxytocin
• Thyroxin
• Insulin

Explanation: Answer reason: Thyroid hormone increases cellular oxygen consumption and metabolic activity in most tissues, thereby increasing heat production and supporting maintenance of normal body temperature. In hypothyroidism, reduced thyroid hormone commonly leads to cold intolerance and lower heat generation, demonstrating this relationship. Estrogen, oxytocin, and insulin have important reproductive or metabolic roles but are not primary regulators of overall heat production via basal metabolism.

Which hormone is control blood sugar?

• Insuline
• Oxytocin
• ADH
• Leptin

Explanation: Answer reason: This option fits because insulin from pancreatic beta cells lowers blood sugar by promoting glucose uptake in muscle and adipose tissue and increasing glycogen synthesis while suppressing gluconeogenesis. In contrast, oxytocin is mainly involved in uterine contraction and milk ejection, and ADH primarily regulates water balance and serum osmolality. Leptin is a satiety hormone influencing appetite and energy expenditure rather than directly controlling blood glucose concentration.

Androgens are a group of?

• Carbohydrates
• Enzymes
• Male sex hormones
• Red blood cells

Explanation: Answer reason: Testosterone and dihydrotestosterone are the principal examples, produced mainly by the testes (and in smaller amounts by the adrenal glands and ovaries). Their physiologic actions occur through intracellular androgen receptors that regulate gene transcription, which is characteristic of endocrine hormones rather than enzymes or nutrients. Red blood cells are cellular blood components, and carbohydrates are macronutrients, so neither fits the definition of androgens.

The hormone responsible for maintenance of pregnancy is-?

• Estrogen
• Progesterone
• HCG
• Human placental lactogen

Explanation: Answer reason: Early in pregnancy it is produced by the corpus luteum, and after the luteal–placental shift the placenta becomes the main source, continuing this supportive effect. Loss or inadequate levels can lead to endometrial instability and increased uterine activity, raising miscarriage risk. In contrast, hCG primarily serves to “rescue” the corpus luteum so it can keep producing progesterone, rather than directly maintaining pregnancy long-term. Estrogen and human placental lactogen have important roles in uterine growth and maternal metabolic adaptations, but they are not the primary hormone preventing pregnancy loss.

Which of the following are a result of antidiuretic hormone (ADH) secretion?

• Potassium excretion and water reabsorption
• Urine dilution
• Sodium and water reabsorption
• Urine concentration

Explanation: Answer reason: This reduces urine volume and raises urine osmolality, producing more concentrated urine. Urine dilution occurs when ADH is low or absent, so that water is not reabsorbed in the collecting ducts. Sodium reabsorption is primarily regulated by aldosterone rather than ADH, making that option less directly tied to the core physiologic effect being tested.

What is the name of the hormone that is responsible for triggering the fight or flight response?

• Adrenaline
• Cortisol
• Thyroxine
• Insulin

Explanation: Answer reason: This produces immediate physiologic changes such as increased heart rate and contractility, bronchodilation, pupillary dilation, and mobilization of glucose for quick energy. Cortisol supports a more prolonged stress response by altering metabolism and immune activity, but its onset is slower and not the primary immediate trigger. Thyroxine regulates baseline metabolic rate and growth, and insulin primarily lowers blood glucose, so neither drives the acute stress surge.

Which hormone regulates blood sugar levels in the human body?

• Insulin
• Thyroxine
• Adrenaline
• Glucagon

Explanation: Answer reason: When blood glucose rises after eating, pancreatic beta cells release insulin to prevent hyperglycemia. In contrast, glucagon mainly raises blood glucose during fasting by stimulating glycogenolysis and gluconeogenesis. Thyroxine affects basal metabolic rate, and adrenaline can acutely increase glucose during stress, but neither is the principal regulator of day-to-day glucose homeostasis.

What is the primary cause of hyperparathyroidism?

• Parathyroid adenoma
• Thyroid carcinoma
• Adrenal hyperplasia
• Chronic kidney disease

Explanation: Answer reason: This leads to increased bone resorption, renal calcium reabsorption, and increased calcitriol activation, producing hypercalcemia. Chronic kidney disease is a classic cause of secondary hyperparathyroidism via hyperphosphatemia and low calcitriol, not the primary form asked here. Thyroid carcinoma and adrenal hyperplasia do not directly produce parathyroid hormone excess.

What is the main function of the thyroid gland?

• Regulate metabolism
• Control blood pressure
• Produce insulin
• Maintain bone density

Explanation: Answer reason: This is the thyroid gland’s primary physiologic role and explains classic hyperthyroid (weight loss, heat intolerance) and hypothyroid (weight gain, cold intolerance) patterns. Blood pressure can be influenced indirectly via metabolic and adrenergic effects, but it is not the gland’s main function. Insulin production is a pancreatic beta-cell function, and bone density is primarily regulated by calcium/phosphate balance and other hormones (with thyroid calcitonin playing only a minor role clinically).

Which hormone causes uterine contractions during childbirth?

• Prolactin
• Estrogen
• Oxytocin
• Progesterone

Explanation: Answer reason: Uterine contractions in labor are primarily driven by a neuroendocrine reflex where increased cervical stretch triggers posterior pituitary release of a hormone that intensifies myometrial contractility. This mechanism creates a positive feedback loop (Ferguson reflex) that strengthens and coordinates contractions to facilitate delivery. Prolactin mainly supports milk production, not myometrial contraction. Progesterone generally maintains uterine quiescence during pregnancy, so it would not be the main mediator of labor contractions.

What is the primary function of insulin?

• To increase blood glucose levels
• To decrease blood glucose levels
• To regulate the menstrual cycle
• To stimulate the production of breast milk

Explanation: Answer reason: It also supports glycogen synthesis and suppresses gluconeogenesis and glycogenolysis, which further reduces circulating glucose. A common distractor is increasing glucose, which is primarily the role of counterregulatory hormones like glucagon and epinephrine. Menstrual cycle regulation and breast milk production are mediated mainly by gonadotropins/sex steroids and prolactin, not insulin.

Which gland is often referred to as the 'master gland'?

• Pineal Gland
• Adrenal Gland
• Thyroid Gland
• Pituitary Gland

Explanation: Answer reason: The anterior pituitary releases TSH, ACTH, LH/FSH, GH, and prolactin, thereby controlling thyroid, adrenal cortex, and gonadal function and influencing growth and lactation. Although the hypothalamus is the primary controller via releasing hormones, the pituitary is classically termed the “master gland” because its hormones directly drive multiple peripheral glands. The pineal primarily regulates circadian rhythms (melatonin), while thyroid and adrenal glands are major effectors rather than central regulators.

Which hormone is primarily responsible for the "fight or flight" response?

• Insulin
• Epinephrine (Adrenaline)
• Estrogen
• Melatonin

Explanation: Answer reason: This hormone increases heart rate and contractility, causes bronchodilation, and mobilizes glucose via glycogenolysis and lipolysis to provide immediate energy. These physiologic effects match the fast, short-term stress response described. A common distractor is insulin, which promotes glucose uptake and storage and is not a stress-activation hormone.

What is the disease caused by the deficiency of insulin production?

• Diabetes Mellitus
• Diabetes Insipidus
• Hypothyroidism
• Hyperthyroidism

Explanation: Answer reason: This mechanism defines diabetes mellitus, particularly type 1 diabetes where pancreatic beta-cell failure results in absolute insulin deficiency. In contrast, diabetes insipidus is due to deficient or ineffective ADH, causing dilute polyuria without hyperglycemia. Thyroid disorders primarily alter metabolic rate via T3/T4 and are not caused by insulin deficiency.

Which system regulates hormones in the body?

• Nervous system
• Endocrine system
• Circulatory system
• Digestive system

Explanation: Answer reason: This gland-based signaling network is the core function of the endocrine system (e.g., pituitary, thyroid, adrenals, pancreas, gonads). The nervous system can modulate endocrine activity via the hypothalamus, but it primarily communicates through electrical impulses and neurotransmitters rather than systemic hormone secretion. The circulatory system mainly transports hormones, and the digestive system primarily focuses on nutrient breakdown and absorption rather than overall hormonal regulation.

Management of gestational diabetes mellitus (GDM) is usually done with?

• PO hypoglycemic drugs
• Nutritional therapy
• NPH Insulin injections
• All of the above

Explanation: Answer reason: Many patients can meet glycemic goals with diet (often paired with activity) without needing medications, making it the usual initial management approach. Insulin is added when fasting or postprandial targets are not met despite nutrition therapy. Oral hypoglycemics are not universally preferred in pregnancy and are generally considered second-line/alternative depending on guideline and clinical context, so they are not the usual default.

Ms. ALM has been diagnosed with Hashimoto's disease, an autoimmune disorder. Which of the following signs and symptoms were most probably exhibited by the client that led to the diagnosis?

• Increased appetite, weight loss, hyperdefecation
• Increased urination, weight loss, increased thirst
• Decreased appetite, weight gain, constipation
• Increased urination, weight gain, and purplish red striae

Explanation: Answer reason: A slowed metabolism produces weight gain despite reduced appetite and decreases gastrointestinal motility, causing constipation. In contrast, increased appetite with weight loss and frequent stools aligns with hyperthyroidism, not Hashimoto’s typical presentation. Polyuria, polydipsia, and weight loss suggest diabetes mellitus, while purplish striae with weight gain suggests hypercortisolism (Cushing syndrome).

During a health history, a 59-year-old male client is being evaluated for possible type 2 diabetes mellitus. Which of the following client statements support the diagnosis of type 2 diabetes?

• I have some shortness of breath when I exercise.
• No matter how much I drink, I'm still thirsty all the time.
• I wake up early in the morning and I can't return to sleep.
• In the past couple of weeks, I've been having a lot of trouble urinating.

Explanation: Answer reason: Persistent polydipsia is a classic symptom of hyperglycemia due to osmotic diuresis from glucosuria, which increases urine output and drives dehydration and thirst. This symptom is commonly reported in type 2 diabetes, especially when blood glucose has been elevated for some time. By contrast, exertional dyspnea and insomnia are nonspecific and do not directly reflect glucose dysregulation. “Trouble urinating” suggests dysuria/obstruction rather than the increased urination (polyuria) expected with uncontrolled diabetes.

What is the primary function of glucagon?

• To increase blood glucose levels
• To decrease blood glucose levels
• To regulate the menstrual cycle
• To stimulate the production of breast milk

Explanation: Answer reason: It raises plasma glucose primarily by stimulating hepatic glycogenolysis and gluconeogenesis, increasing glucose release into the bloodstream. In contrast, lowering blood glucose is the role of insulin, not glucagon. Menstrual cycle regulation and lactation are mediated by gonadotropins/sex steroids and prolactin/oxytocin, respectively, not by glucagon.

Which of the following is the main function of the endocrine system?

• To produce hormones that control growth and metabolism
• To exchange gases between the air and the blood
• To break down food into smaller molecules that can be absorbed
• To eliminate solid and liquid wastes from the body

Explanation: Answer reason: These hormones control growth, development, metabolism, reproduction, and stress responses through feedback loops (e.g., hypothalamic-pituitary axes). Gas exchange is primarily a respiratory system function, digestion is gastrointestinal, and waste elimination is mainly renal and gastrointestinal. Therefore, the option describing hormone production and regulation of growth/metabolism best matches endocrine function.

The hormone that regulates kidney water balance is?

• ADH
• Insulin
• Thyroxine
• Estrogen

Explanation: Answer reason: ADH (vasopressin) is the primary hormone that controls water reabsorption in the kidneys by increasing collecting duct permeability via aquaporin insertion. When ADH rises, urine becomes more concentrated and urine volume decreases, helping maintain plasma osmolality and circulating volume. Insulin primarily regulates glucose and potassium shifts rather than renal free-water handling. Thyroxine and estrogen can influence metabolism and fluid status indirectly but are not the key direct regulators of kidney water balance tested here.

A client is being treated for Addison’s disease. The physician orders cortisone 25 mg PO daily. The nurse should explain to the client that adjustment of the dosage may be required in which of the following situations?

• Dosage is increased when the blood glucose level increases.
• Dosage is decreased when dietary intake is increased.
• Dosage is decreased when infection stimulates endogenous steroid secretion.
• Dosage is increased relative to an increase in the level of stress.

Explanation: Answer reason: Physiologic stress normally triggers increased cortisol output; in Addison’s disease, the adrenal cortex cannot mount this response, so exogenous glucocorticoids must be “stress-dosed” to prevent adrenal crisis. Illness, surgery, trauma, or significant psychological stress can all increase cortisol requirements beyond the baseline replacement dose. Hyperglycemia is more commonly an adverse effect of glucocorticoids rather than an indication to increase replacement dosing. Infection does not reliably increase endogenous steroid secretion in primary adrenal insufficiency, so dose reduction during infection would be unsafe.

Which hormone is primarily responsible for regulating blood sugar levels by facilitating the uptake of glucose into cells?

• Glucagon
• Adrenaline
• Insulin
• Cortisol

Explanation: Answer reason: By increasing cellular uptake and storage of glucose, it directly reduces circulating blood sugar after meals. In contrast, glucagon raises blood glucose primarily via hepatic glycogenolysis and gluconeogenesis. Stress hormones like adrenaline and cortisol also tend to increase glucose availability rather than drive uptake into cells.

What is the primary product of photosynthesis that plants use for energy?

• Oxygen
• Carbon Dioxide
• Glucose
• ATP

Explanation: Answer reason: The main stable energy-rich molecule produced is glucose, which can be metabolized via cellular respiration or stored as starch for later use. Oxygen is primarily a byproduct released from water splitting rather than the energy source. Carbon dioxide is a reactant that is fixed into sugars, while ATP made in the light reactions is used transiently to build sugars and is not the end product used for longer-term energy needs.

Intravenous therapies often consist of electrolyte replacement therapies. Select the electrolyte that is accurately paired with one of its functions?

• Phosphate: The operation of the sodium potassium pump (The production of DNA and ATP)
• Potassium: The regulation of extracellular fluid (ICF)
• Chloride: The regulation of ICF (ECF)
• Calcium: Blood clotting

Explanation: Answer reason: Calcium is an essential cofactor in multiple steps of the coagulation cascade, enabling activation of clotting factors and formation of a stable fibrin clot. This makes its pairing with blood clotting physiologically accurate and clinically relevant when considering electrolyte replacement and bleeding risk. Potassium is primarily an intracellular cation that supports membrane potential and neuromuscular function, not extracellular fluid regulation. Chloride is the major extracellular anion involved in osmotic balance and acid–base regulation, so linking it to ICF is incorrect.

All sense organs send information to the brain via?

• Muscles
• Hormones
• Nerves
• Blood

Explanation: Answer reason: Afferent (sensory) neurons carry these impulses via peripheral and cranial nerves to the spinal cord/brain for processing and perception. Hormones and blood are chemical/transport systems and do not provide fast, point-to-point encoding of sensory modality and intensity. Muscles are effectors that respond to neural output rather than being the primary pathway for sensory input.

Which part of the body receives no blood?

• Tongue
• Teeth
• Eyes
• None

Explanation: Answer reason: The tongue is highly vascular, with a rich arterial supply supporting muscular activity and taste. Teeth are supplied via the dental pulp and periodontal tissues through branches of the maxillary artery. The eyes also have substantial blood supply (e.g., retinal and ciliary circulations) to support high metabolic demand, so no listed structure is truly bloodless.

Water Percentage in plasma is?

• 70%
• 90%
• 100%
• 120%

Explanation: Answer reason: Standard physiology describes plasma as about 90–92% water by volume, which supports transport and maintains osmotic balance and viscosity. Values like 70% are closer to total body water in some contexts, not plasma composition. Values of 100% or 120% are physiologically impossible for a percentage composition of a component.

Other name of water intoxication or water intoxication is related to ...?

• Isotonic overhydration
• Hypotonic overhydration
• Hypertonic overhydration
• All of above

Explanation: Answer reason: The lowered serum osmolality drives water into cells, particularly brain cells, causing cerebral edema with symptoms such as headache, confusion, seizures, and coma. This matches hypotonic overhydration rather than isotonic overhydration, which expands extracellular volume without lowering sodium concentration. Hypertonic overhydration implies excess sodium relative to water and would raise osmolality, producing opposite fluid shifts.

Which process describes the movement of molecules from high to low concentration?

• Active transport
• Diffusion
• Osmosis
• Endocytosis

Explanation: Answer reason: This describes diffusion, where solute particles spread until equilibrium is approached. Active transport is a key distractor because it moves substances against the gradient and requires ATP. Osmosis is a specific type of diffusion involving water across a semipermeable membrane, and endocytosis is vesicular bulk transport rather than gradient-driven particle movement.

What is the primary function of the lymphatic system?

• Transport oxygen
• Return interstitial fluid to blood
• Digest fats
• Produce hormones

Explanation: Answer reason: This prevents edema and supports effective blood volume and pressure. While lymphatics also transport dietary lipids from the intestine (via lacteals) and support immune surveillance, these are secondary compared with its core drainage/return function. Oxygen transport is a role of red blood cells in the cardiovascular system, and hormone production is an endocrine function.

The nurse is caring for a client having respiratory distress related to an anxiety attack. Recent arterial blood gas values are pH = 7.53, PaO2 = 72 mm Hg (72 mm Hg), PaCO2 = 32 mm Hg (32 mmHg), and HCO3- = 28 mEq/L (28 mmol/L). Which conclusion about the client should the nurse make?

• The client has acidic blood.
• The client is probably overreacting.
• The client is fluid volume overloaded.
• The client is probably hyperventilating.

Explanation: Answer reason: The core principle is ABG interpretation: elevated pH indicates alkalemia, and a low PaCO2 points to a primary respiratory alkalosis. Hyperventilation from anxiety causes excessive CO2 blow-off, lowering PaCO2 and raising pH, which matches these findings. The PaO2 of 72 mm Hg suggests mild hypoxemia, which can accompany anxiety-related tachypnea and ventilation–perfusion mismatch. “Acidic blood” is inconsistent with the alkalemic pH, and “overreacting” is a non-clinical, inappropriate conclusion.

Which cells in our body are popularly called "soldiers of the human body"?

• Basophils
• Red Blood Cell
• White Blood Cell
• Eosinophils

Explanation: Answer reason: These cells migrate to sites of injury or infection, participate in inflammation, and coordinate immune responses through phagocytosis and antibody/cytokine-mediated mechanisms. Because they actively protect the body, they are commonly referred to as the “soldiers” of the body. Red blood cells mainly transport oxygen and carbon dioxide, while basophils and eosinophils are only specific subtypes of leukocytes rather than the broad group implied by the question.

What is the process by which water moves across a cell membrane?

• Osmosis
• Diffusion
• Active transport
• Endocytosis

Explanation: Answer reason: This passive movement of water is termed osmosis and does not require cellular energy (ATP). Diffusion is a broader term for solute movement down a concentration gradient, but the specific term for water movement is osmosis. Active transport and endocytosis are energy-dependent processes used for moving solutes against gradients or bringing in large particles, not for the typical transmembrane movement of water.

Which organelle is responsible for generating energy for the cell?

• Ribosome
• Mitochondria
• Lysosome
• Golgi apparatus

Explanation: Answer reason: Mitochondria house the Krebs cycle and the electron transport chain, which generate the bulk of ATP used for cellular work. Ribosomes synthesize proteins, lysosomes digest cellular debris, and the Golgi apparatus modifies and packages proteins/lipids rather than producing ATP. Therefore the organelle most directly responsible for energy generation is the one specialized for ATP production.

Which part of the ear is responsible for balance?

• Cochlea
• Eustachian tube
• Semicircular canals
• Tympanic membrane

Explanation: Answer reason: The semicircular canals sense angular (rotational) acceleration via endolymph movement that bends hair cells in the crista ampullaris. This provides key input for the vestibulo-ocular reflex and equilibrium. In contrast, the cochlea is specialized for hearing, while the Eustachian tube equalizes middle-ear pressure and the tympanic membrane transmits sound vibrations.

What is the primary function of the red blood cells?

• To fight infections
• To carry oxygen
• To digest food
• To regulate body temperature

Explanation: Answer reason: This function is the primary role of erythrocytes in supporting cellular aerobic metabolism. Fighting infection is mainly performed by white blood cells, not erythrocytes. While blood flow can influence heat distribution, thermoregulation is not the primary purpose of red blood cells.

What is the process by which water moves through a plant?

• Respiration
• Photosynthesis
• Transpiration
• Osmosis

Explanation: Answer reason: This evaporation generates negative pressure (tension) that pulls a continuous column of water upward through the xylem via the cohesion-tension mechanism. This explains whole-plant, long-distance transport from roots to leaves. Osmosis is important for water entering root cells locally, but it does not account for the bulk upward flow through vascular tissue.

What is the term for the movement of molecules from high to low concentration?

• Osmosis
• Diffusion
• Mitosis
• Meiosis

Explanation: Answer reason: This process does not require cellular energy (ATP) and occurs in gases and liquids and across permeable membranes. Osmosis is a specific type of diffusion referring only to water moving across a semipermeable membrane. Mitosis and meiosis are cell division processes and are unrelated to concentration-gradient particle movement.

The powerhouse of the cell is —?

• Nucleus
• Ribosome
• Mitochondria
• Golgi body

Explanation: Answer reason: This occurs primarily via the Krebs cycle and electron transport chain located in the mitochondrial matrix and inner membrane. Because most ATP for normal cell function is produced there, this organelle is termed the cell’s “powerhouse.” By contrast, the nucleus regulates genetic information, ribosomes synthesize proteins, and the Golgi apparatus modifies and packages proteins.

Which of the following parts of the brain controls body temperature and hunger?

• Thalamus
• Pond
• Hypothalamus
• Cerebellum

Explanation: Answer reason: The hypothalamus contains temperature-regulating nuclei (including the preoptic area) that coordinate heat production and heat loss responses via autonomic output. It also regulates hunger and satiety through hypothalamic nuclei (e.g., lateral hypothalamus and ventromedial/arcuate pathways) and hormonal signals such as leptin and ghrelin. In contrast, the thalamus mainly relays sensory information, and the cerebellum primarily coordinates movement and balance, making them poor fits for these homeostatic roles.

The mother of a newborn child calls the pediatrician’s office with concern that her child is often jolted or startled when waking from sleep. What reflex is the mother likely witnessing?

• Moro
• Routing
• Babinski
• Tonic neck

Explanation: Answer reason: It is commonly noticed when infants are awakened or startled by noise or movement, matching the mother’s description. Rooting is a feeding-related reflex elicited by stroking the cheek, Babinski is an upgoing plantar response to sole stimulation, and tonic neck is a postural “fencing” response to head turning. Persistence of a strong Moro beyond early infancy can be abnormal, but its presence in a newborn is expected.

The last physiologic function that the client lose during the induction of anesthesia is?

• Consciousness
• Cough reflex
• Respiratory movement
• Voluntary muscle control

Explanation: Answer reason: Loss of awareness occurs early, and protective airway reflexes such as coughing are blunted as anesthetic depth increases. Spontaneous breathing is maintained until deeper levels when the medullary respiratory center is significantly depressed, making this function the last to be lost. Clinically, this is why ventilation must be closely monitored and airway support is instituted as depth increases, even after the patient is unconscious.

A 60-year-old man with diabetes mellitus, hypertension, hyperlipidemia, and chronic renal insufficiency is admitted to the hospital because of lightheadedness. His medications include NPH insulin, amlodipine, and simvastatin. He is allergic to penicillin to which he gets an angioedema. His temperature is 37.1 C (98.8 F), blood pressure is 98/65 mm Hg, pulse is 87/min, and his respiratory rate is 22/min. On exam, he is ill appearing. His cardiac rhythm is regular and breath sounds are clear bilaterally. His abdominal exam is benign. A chest radiograph shows clear lungs. An electrocardiogram shows a sinus rhythm with peaked T waves. Laboratory studies show a serum sodium of 134 mEq/L, glucose of 98 mg/dL, and potassium of 6.2 mEq/L. The most appropriate intervention at this time is?

• Administration of glucose, orally
• Administration of insulin and glucose, intravenously
• Administration of furosemide, orally
• Administration of ringers lactate, intravenously

Explanation: Answer reason: Insulin rapidly shifts potassium into cells by stimulating the Na+/K+-ATPase, and concomitant dextrose prevents iatrogenic hypoglycemia, especially since the serum glucose is normal. Oral glucose alone will not correct the potassium and is too slow/inadequate for ECG-evident hyperkalemia. Oral furosemide may promote renal potassium excretion but is slower, depends on kidney function (he has chronic renal insufficiency), and does not address the immediate electrical risk; lactated Ringer’s contains potassium and can worsen hyperkalemia.

Which of the following is a type of tissue that contracts and produces movement?

• Epithelial tissue
• Connective tissue
• Muscle tissue
• Nervous tissue

Explanation: Answer reason: This contractile function is the defining property of muscle tissue (skeletal, cardiac, and smooth), allowing locomotion, pumping blood, and peristalsis. Epithelial tissue mainly provides lining, secretion, and absorption rather than force generation. Nervous tissue conducts electrical impulses to coordinate activity but does not itself produce movement by contracting.

A plant cell shrinks when placed in?

• A hypertonic solution
• A hypotonic solution
• Water
• A solution is isotonic with the cell sap

Explanation: Answer reason: In a hypertonic external solution, the surrounding fluid has a higher solute concentration than the plant cell sap, so water exits the cell. Loss of intracellular water decreases turgor pressure and causes the protoplast to pull away from the cell wall (plasmolysis), producing shrinkage. In hypotonic solutions or pure water, water enters and the cell becomes turgid rather than shrinking, while isotonic conditions produce no net size change.

Amount of water excreted as urine per day is about?

• 1000 ml
• 1500 ml
• 100 ml
• 500 ml

Explanation: Answer reason: In a typical hydrated adult, a commonly cited approximate daily urine volume is about 1500 mL. Values like 100 mL/day would indicate severe oliguria/anuria, and 500 mL/day suggests oliguria, both abnormal for most adults. 1000 mL/day can occur but is less representative of the standard average used in physiology exam questions.

What is the process by which the body maintains a stable internal environment?

• Homeostasis
• Metabolism
• Reproduction
• Adaptation

Explanation: Answer reason: This concept directly describes regulation of temperature, pH, glucose, blood pressure, and fluid balance to maintain internal stability. Metabolism refers to chemical reactions for energy use and biosynthesis, not the stability-maintaining control process itself. Adaptation is longer-term adjustment to environment and is broader than the moment-to-moment internal regulation being asked.

What is the term for the movement of molecules from high to low concentration?

• Osmosis
• Diffusion
• Active transport
• Endocytosis

Explanation: Answer reason: This is the defining feature of diffusion and explains how many solutes and gases distribute across fluids and membranes. Osmosis is a specific type of diffusion referring only to water moving across a semipermeable membrane. Active transport and endocytosis are energy-dependent mechanisms used to move substances against gradients or via vesicular uptake, respectively.

Which part of the brain regulates body temperature?

• Cerebrum
• Cerebellum
• Hypothalamus
• Medulla oblongata

Explanation: Answer reason: The hypothalamus acts as the body’s “thermostat,” sensing blood temperature and coordinating heat-loss (sweating, vasodilation) and heat-gain (shivering, vasoconstriction) responses. It also mediates fever by resetting the temperature set point in response to pyrogens via prostaglandin pathways. By contrast, the cerebrum primarily handles higher cognition and voluntary actions, and the medulla mainly regulates vital autonomic functions like respiration and heart rate rather than temperature set-point control.

What is the term for the movement of molecules against a concentration gradient?

• Diffusion
• Osmosis
• Active transport
• Passive transport

Explanation: Answer reason: This distinguishes it from diffusion and osmosis, which are passive processes that occur down a concentration gradient without cellular energy expenditure. Passive transport is an umbrella term for gradient-driven movement and therefore cannot describe movement against the gradient. A classic physiologic example is the sodium-potassium ATPase maintaining resting membrane potentials by pumping ions against their gradients.

What is the normal Intracranial pressure?

• 20-30 mmHg
• 30-40 mmHg
• 5-15 mmHg
• 0-10 mmHg

Explanation: Answer reason: Typical resting values are about 5–15, and sustained elevations above ~20 are treated as intracranial hypertension. This range best matches expected physiologic measurements used in neuro monitoring. The higher ranges listed would more likely indicate pathologic elevation rather than normal baseline.

What is the term for the movement of substances across a cell membrane without using energy?

• Active transport
• Passive transport
• Osmosis
• Diffusion

Explanation: Answer reason: This umbrella term includes simple diffusion, facilitated diffusion, and osmosis, all of which occur without direct energy expenditure. The stem asks for the general term rather than a specific subtype, making this the best match. A common distractor is active transport, which by definition requires energy to move substances against a gradient.

A nurse is caring for a client with the following arterial blood gases: HCO3 of 18 mEq (22–26), CO2 of 28 mmHg (35–45). Which of the following pH values and acid base imbalances would accompany these values?

• Decreased pH and metabolic acidosis
• Decreased pH and respiratory acidosis
• Elevated pH and metabolic alkalosis
• Elevated pH and respiratory alkalosis

Explanation: Answer reason: The CO2 is also low, which is the expected respiratory compensation (hyperventilation) to blow off acid and raise pH toward normal. Since the primary abnormality is decreased bicarbonate, the accompanying pH would be decreased (acidemia) rather than elevated. Respiratory acidosis would require an elevated CO2, which is not present here.

The nurse is caring for a client with several broken ribs. The client is most likely to experience what type of acid-base imbalance?

• Respiratory acidosis from inadequate ventilation
• Respiratory alkalosis from anxiety and hyperventilation
• Metabolic acidosis from calcium loss due to broken bones
• Metabolic alkalosis from taking analgesics containing base products

Explanation: Answer reason: Increased PaCO2 shifts the carbonic acid–bicarbonate buffer toward more hydrogen ions, lowering pH and producing respiratory acidosis. This is the most direct and likely acid–base effect of impaired ventilation in thoracic trauma. Anxiety-related hyperventilation can occur, but sustained hyperventilation is less typical than guarded, shallow breathing when rib pain is significant.

Which phenomena is defined as a subjective human experience that is what the client says it is, it exists when the client says it is present. Does it alert humans to actual or potential bodily tissue damage?

• Anxiety
• Pain
• Fear
• Perception

Explanation: Answer reason: Pain is classically defined as whatever the experiencing person says it is and existing whenever they say it does, emphasizing its subjective nature. It is also a protective physiologic phenomenon that serves as a warning signal of actual or potential tissue damage (nociception) and prompts avoidance or care-seeking behaviors. Anxiety and fear are emotional states related to perceived threat, but they are not defined by the tissue-damage warning function. Perception is a broad cognitive process and is not the specific clinical phenomenon described by this standard definition.

The nurse is discussing biological clocks with another nurse. What term is used to describe a human's innate biological clock relating to daytime and nighttime wakefulness and activity?

• REM sleep
• Circadian rhythm
• Diurnal rhythm
• Nocturnal activity

Explanation: Answer reason: Circadian rhythms are endogenous ~24-hour cycles that regulate the sleep–wake pattern and daily fluctuations in alertness, core temperature, and hormone secretion. The question asks for the innate biologic clock governing day–night wakefulness, which is the definition of circadian rhythm (driven by the suprachiasmatic nucleus and influenced by light). REM sleep is a specific sleep stage rather than the overarching timing system that schedules sleep and wake. Diurnal and nocturnal describe patterns of activity (day-active vs night-active) but do not specifically name the internal clock mechanism.

Which of the following is responsible for oxygen transport in human blood?

• Hemoglobin
• Myoglobin
• Plasma proteins
• Leukocytes

Explanation: Answer reason: This allows large amounts of oxygen to be carried from the lungs to tissues while keeping dissolved plasma oxygen relatively low. Myoglobin mainly stores oxygen within muscle cells rather than transporting it through circulation. Leukocytes and plasma proteins have immune and oncotic/transport functions, but they are not the principal carriers of oxygen.

What is the term for the movement of molecules from high to low concentration?

• Active transport
• Osmosis
• Diffusion
• Endocytosis

Explanation: Answer reason: This describes how gases like oxygen and carbon dioxide move across alveolar-capillary membranes and how many solutes spread in fluids. Osmosis is a specific type of diffusion limited to water moving across a semipermeable membrane, so it is narrower than the stem’s general “molecules” wording. Active transport and endocytosis are energy-dependent processes and are not defined by movement from high to low concentration.

Which organelle is known as the "powerhouse" of the cell because it generates most of the cell's supply of ATP?

• Nucleus
• Ribosome
• Mitochondria
• Golgi Apparatus

Explanation: Answer reason: This organelle contains the electron transport chain and ATP synthase, which generate the majority of ATP in most human cells. The nucleus mainly stores genetic material and regulates transcription, while ribosomes synthesize proteins and the Golgi modifies/packages proteins for transport. Therefore, the organelle responsible for most ATP generation is the mitochondrion.

Which process involves the movement of molecules against their concentration gradient?

• Diffusion
• Osmosis
• Active transport
• Passive transport

Explanation: Answer reason: This is the defining feature of transport from lower concentration to higher concentration to maintain cellular homeostasis (e.g., Na+/K+ ATPase). Diffusion and osmosis are passive processes that move substances down their gradients without energy expenditure. “Passive transport” is a broad category that explicitly excludes movement against the gradient, making it incorrect here.

Which organelle is responsible for synthesizing proteins in both eukaryotic and prokaryotic cells?

• Mitochondria
• Ribosome
• Golgi Apparatus
• Nucleus

Explanation: Answer reason: Prokaryotes lack membrane-bound organelles, but still have 70S ribosomes to produce all cellular proteins. Eukaryotic cells use 80S ribosomes in the cytosol and on rough ER, with additional ribosomes in mitochondria/chloroplasts. In contrast, the Golgi modifies and packages proteins after they are made, and the nucleus is primarily involved in transcription and genetic regulation rather than translation.

Which organelle is known as the "suicide bag" of the cell because it contains digestive enzymes?

• Mitochondria
• Lysosome
• Golgi Apparatus
• Nucleolus

Explanation: Answer reason: If their membrane ruptures or enzymes are released inappropriately, these enzymes can digest cellular components, leading to autolysis—hence the nickname “suicide bag.” Mitochondria primarily generate ATP and regulate apoptosis signaling but are not the main storage site of digestive enzymes. The Golgi apparatus modifies and packages proteins, while the nucleolus is involved in rRNA synthesis and ribosome assembly.

Which organelle is responsible for synthesizing lipids and detoxifying poisons in the cell?

• Rough Endoplasmic Reticulum
• Golgi Apparatus
• Smooth Endoplasmic Reticulum
• Lysosome

Explanation: Answer reason: Its lack of ribosomes reflects that it is not primarily involved in protein synthesis. Rough ER is the main site of synthesis for secreted and membrane proteins, not lipid detox functions. Golgi mainly modifies and packages proteins/lipids for transport, and lysosomes perform intracellular digestion rather than detoxification and lipid production.

Which of the following is the function of the human liver?

• Production of bile
• Metabolisation of fat
• Metabolisation of carbohydrate
• All of the above

Explanation: Answer reason: It synthesizes and secretes bile, which is essential for emulsification and absorption of dietary lipids. It is a central site for lipid metabolism (e.g., fatty acid oxidation, lipoprotein synthesis, and cholesterol/bile acid handling) and for carbohydrate metabolism (e.g., glycogenesis, glycogenolysis, and gluconeogenesis) to maintain blood glucose. Because each listed function is a recognized hepatic role, the inclusive choice is the most accurate.

What is the primary purpose of Mitosis?

• Production of gametes (sperm/egg)
• Genetic diversity
• Growth and tissue repair
• Reducing the chromosome number by half

Explanation: Answer reason: This supports organismal growth and replacement of worn-out or damaged cells during tissue maintenance and wound healing. In contrast, producing gametes and reducing chromosome number by half are defining purposes of meiosis, not mitosis. Genetic diversity primarily arises from meiotic recombination and independent assortment, which do not occur in standard mitotic division.

Which organelle is known as the "post office" of the cell because it packages and ships proteins?

• Mitochondria
• Golgi Apparatus
• Lysosome
• Endoplasmic Reticulum

Explanation: Answer reason: The Golgi complex modifies, sorts, and packages proteins into vesicles for secretion or delivery to specific intracellular destinations, analogous to a cell’s shipping center. Proteins synthesized on ribosomes enter the rough ER first for initial folding and processing, then are transported to the Golgi for further maturation (e.g., glycosylation) and labeling. Mitochondria primarily generate ATP, and lysosomes are degradative organelles that digest macromolecules rather than export them. Therefore, the organelle responsible for packaging and “shipping” proteins is the Golgi apparatus.

What is the term for the study of the structure and function of tissues?

• Histology
• Cytology
• Ecology
• Embryology

Explanation: Answer reason: This field examines tissue types (epithelial, connective, muscle, nervous), their organization, and structure–function correlations in health and disease. Cytology is a common distractor because it studies cells, but it does not primarily address the organization of cells into tissues. Ecology and embryology address organism–environment relationships and developmental processes, respectively, not tissue structure and function.

The intensive care unit (ICU) nurse receives a phone call stating a client diagnosed with a head trauma must undergo admission. There are no empty beds. Which client is most stable and eligible for a transfer to the step-down neurological unit?

• A client diagnosed with increased intracranial pressure (ICP) and who has a Glasgow Coma Scale of 8.
• A client diagnosed with a cervical spinal injury 3 days ago with halo traction.
• A client diagnosed with a cerebrovascular accident (CVA) and subdural hematoma 1 day ago.
• A client diagnosed with increased intracranial pressure (ICP) and a tracheostomy.

Explanation: Answer reason: Triage and bed management prioritize keeping ICU-level care for clients at highest risk of rapid neurologic or airway deterioration. A client 3 days post–cervical spinal injury in halo traction is typically hemodynamically and neurologically more stable once acute swelling and immediate post-injury instability have passed, and ongoing care is focused on immobilization and monitoring that can be managed in a neuro step-down setting. In contrast, increased ICP with a GCS of 8 signals severe brain injury with high risk for herniation and need for intensive neurologic monitoring/airway support. A CVA with a subdural hematoma just 1 day ago is also early and unstable, with significant risk for expanding bleed and worsening mental status requiring ICU resources.

Several patients are taking antipsychotic medications and are having medication side effects. Place the following patients in priority order for additional assessment and appropriate interventions, with 1 being the most critical and 4 being the least?

• A patient who is taking trifluoperazine and has a temperature of 103.6°F (39.8°C) with tachycardia, muscular rigidity, and dysphagia
• A patient who is taking fluphenazine and has dry mouth and dry eyes, urinary hesitancy, constipation, and photosensitivity
• A patient who is taking loxapine and has a protruding tongue with lip smacking and spastic facial distortions
• A patient who is taking clozapine and reports a sore throat, fever, malaise, and flulike symptoms that began about 6 weeks ago after starting the new antipsychotic medication; white blood cell count is 2000/mm3 (2.0 × 109/L)

Explanation: Answer reason: A patient who is taking trifluoperazine and has a temperature of 103.6°F (39.8°C) with tachycardia, muscular rigidity, and dysphagia These findings are classic for neuroleptic malignant syndrome, a life-threatening antipsychotic reaction requiring immediate emergency assessment, medication discontinuation, and rapid supportive care (airway/ventilation, cooling, IV fluids) to prevent rhabdomyolysis, renal failure, and cardiovascular collapse. The combination of high fever, severe “lead-pipe” rigidity, autonomic instability (tachycardia), and dysphagia signals imminent airway and systemic risk. By comparison, clozapine-associated agranulocytosis is also dangerous but typically allows rapid protective isolation and urgent provider notification rather than the same immediate physiologic instability. Anticholinergic effects and tardive dyskinesia are important but are generally less immediately life-threatening than NMS.

The nurse in the pediatric clinic is triaging telephone messages. The nurse should call the parent of which child first?

• 2-year-old with bilateral tympanostomy tubes who has a small piece of plastic in the right outer ear
• 4-year-old post adenotonsillectomy who is now reporting ear pain
• 5-year-old strep throat who needs a note to return to school 24 hours after starting antibiotics
• 7-year-old 5 days post tonsillectomy who wants to return to soccer practice today

Explanation: Answer reason: Ear pain after adenotonsillectomy can reflect referred throat pain but also can accompany edema, infection, or evolving bleeding risk, so the nurse should screen for airway symptoms, hydration status, and any signs of hemorrhage. A foreign body in the outer ear without respiratory distress is typically nonurgent and can usually wait for a scheduled evaluation. The request for a school note after 24 hours of antibiotics and the question about returning to sports at day 5 are administrative/activity guidance issues and are lower priority than a potential post-op complication.

The nurse has received report on 4 clients. Which client should the nurse see first?

• Client admitted this morning with acute pyelonephritis whose IV line is infiltrated
• Client scheduled for surgery in 2 hours who has questions about the procedure
• Client who had a colostomy yesterday and now has a leaking colostomy bag
• Client with a total hip replacement 3 days ago who reports no bowel movement in 2 days

Explanation: Answer reason: Acute pyelonephritis often requires prompt parenteral therapy, and loss of a functioning line can quickly delay treatment. The other situations are important but are not immediately threatening: a leaking ostomy appliance is a comfort/skin-integrity issue, questions before surgery can be addressed after immediate physiologic needs are stabilized, and no bowel movement for 2 days post-op is common constipation without signs of obstruction. Restoring reliable IV access and assessing the infiltration site should be prioritized first.

A nurse on a cardiovascular unit has received a morning report stating that all clients were stable overnight with stable vital signs. Which client does the nurse assess first?

• The client who is scheduled for coronary artery bypass graft within one hour
• The client who has hemodialysis in one hour and has scheduled metoprolol due
• The client who had three coronary artery stents placed in the cath lab 24 hours ago
• The client who was admitted for non-ST elevation myocardial infarction eight hours ago

Explanation: Answer reason: At 8 hours after admission, this client is still in a high-risk window for recurrent chest pain, evolving ECG changes, and complications from anticoagulants/antiplatelets, so early reassessment is the safest triage choice. Pre-op CABG within an hour is important but typically follows a structured preoperative checklist and monitoring while awaiting transport, and sudden deterioration is less likely than with an active MI. A client 24 hours post-stent is farther from the highest-risk immediate post-procedure period, and dialysis/holding a beta-blocker can be addressed after the highest-acuity cardiac assessment.

The nurse is receiving handoff of care report on 4 clients. Which client should the nurse assess first?

• Client with chronic hypercalcemia who underwent a parathyroidectomy 1 hour ago and has a sore throat and incisional pain
• Client with Cushing syndrome who is scheduled for an adrenalectomy and has bruises and petechiae on the skin
• Client with hyperthyroidism who underwent a thyroidectomy 2 hours ago and is shivering and reporting chills
• Client with type 2 diabetes mellitus who has a foot ulcer and is reporting feeling flushed and thirsty

Explanation: Answer reason: New shivering and chills shortly after thyroid surgery can signal acute hypermetabolic decompensation and/or early systemic infection, both of which can quickly destabilize vital signs and oxygenation. This client needs immediate assessment of temperature, heart rate, blood pressure, mental status, and airway/neck for swelling or bleeding to determine if emergency interventions are needed. In contrast, expected incisional pain and mild sore throat 1 hour after parathyroidectomy are common postoperative findings without immediate red-flag features.

The nurse has been made aware that the following 4 clients require assistance. The nurse should first assist the client who had?

• An abdominal hysterectomy 5 hours ago and is reporting severe incisional pain
• A transurethral resection of the prostate (TURP) yesterday and whose catheter has become disconnected
• A lumbar laminectomy 2 days ago and is complaining that the feet are still numb
• A spinal cord injury at T2 two weeks ago and is currently diaphoretic and nauseated

Explanation: Answer reason: This condition can rapidly progress to severe hypertension, stroke, seizures, or dysrhythmias unless the trigger is removed and blood pressure is treated promptly. The other situations are important but more stable: postoperative pain after hysterectomy is expected, numb feet 2 days post-laminectomy is concerning but typically not as immediately life-threatening, and a disconnected TURP catheter requires correction to maintain irrigation/drainage but is less urgent than a potential autonomic crisis. Therefore, this client must be assessed and managed first with immediate vital signs/BP evaluation and rapid intervention.

The nurse in the emergency department (ED) is assessing a client with multiple injuries that occurred as a result of a motor vehicle collision. Which of the following nursing observations should receive highest priority?

• Avulsion injury of the left index finger
• Deep laceration on the right forearm with blood oozing from the surface
• Hematoma on left side of the neck
• Open fracture of right tibia and fibula

Explanation: Answer reason: A neck hematoma can rapidly expand and compress the airway or indicate major vascular injury (eg, carotid or jugular), making sudden deterioration possible. The other findings represent significant extremity injuries or superficial bleeding but are less likely to cause abrupt airway obstruction in the first moments of assessment. Therefore this observation requires the most urgent evaluation and airway preparedness.

The nurse has received change-of-shift report about the following patients on the progressive care unit. Which patient should the nurse see first?

• A patient who is in a sinus rhythm, rate 98, after having electrical cardioversion 2 hours ago
• A patient with new onset atrial fibrillation, rate 88, who has a first dose of warfarin (Coumadin) due
• A patient with second-degree atrioventricular (AV) block, type 1, rate 60, who is dizzy when ambulating
• A patient whose implantable cardioverter-defibrillator (ICD) fired two times today who has a dose of amiodarone (Cordarone) due

Explanation: Answer reason: This patient may be unstable or deteriorating and needs prompt evaluation of rhythm, hemodynamics, oxygenation, and potential reversible causes (e.g., ischemia, electrolyte abnormalities), as well as timely antiarrhythmic therapy. Amiodarone is commonly used to suppress recurrent ventricular tachyarrhythmias and delaying it increases risk of further shocks and cardiac arrest. By comparison, the post-cardioversion patient is currently in sinus rhythm, the controlled-rate new AF patient awaiting warfarin is not an acute threat, and the type I second-degree AV block with dizziness is concerning but typically less immediately lethal than recurrent ICD firing.

Which client should the postpartum nurse assess first after receiving the a.m. shift report?

• The client who is complaining of perineal pain when urinating.
• The client who saturated multiple peri-pads during the night.
• The client who is refusing to have the newborn in the room.
• The client who is crying because the baby will not nurse.

Explanation: Answer reason: Postpartum assessment priorities follow ABCs and immediate threats, with hemorrhage being a leading cause of maternal morbidity and mortality. Soaking multiple peri-pads suggests heavy lochia and possible uterine atony or retained products, requiring urgent evaluation of fundal tone, vitals, and ongoing blood loss. This finding can rapidly progress to hypovolemic shock, making it higher priority than expected discomforts or feeding difficulties. Pain with urination may indicate irritation or UTI, and emotional/attachment or breastfeeding concerns need support, but they are not as immediately life-threatening as suspected hemorrhage.

The following clients arrive for their appointments at the diabetic clinic. Who should the nurse see first?

• A type 1 diabetes client who feels weak but is eating a simple-carb snack.
• A type 1 diabetes client who needs a dressing change for his foot ulcer.
• A type 2 diabetes client who presents with a headache and a fruity odor on his breath.
• A type 2 diabetes client who will receive education about her diet.

Explanation: Answer reason: Fruity (acetone) breath with symptoms such as headache suggests ketosis with metabolic acidosis, a potentially life-threatening emergency requiring rapid assessment and intervention. This presentation is most consistent with diabetic ketoacidosis (or impending DKA), which can progress to dehydration, electrolyte derangements (notably potassium shifts), and altered mental status. The other clients describe non-urgent or already-addressed concerns (e.g., mild hypoglycemia being treated with carbohydrates, routine wound care, and diet teaching). Prioritizing the client with signs of acute metabolic decompensation follows triage principles of addressing the most unstable, high-risk condition first.

The nurse receives handoff of care report on four clients. Which client should the nurse see first?

• Client with atrial fibrillation who reports feeling palpitations and has an irregular pulse of 122/min
• Client with liver cirrhosis who reports bleeding from an IV insertion site and has a platelet count of 48,000 mm³ (48 × 10⁹/L)
• Client with pericarditis whose blood pressure has decreased from 122/70 mm Hg to 98/68 mm Hg over the past hour
• Client with pneumonia whose white blood cell count has increased from 14,000 mm³ (14 × 10⁹/L) 8 hours ago to 30,000 mm³ (30 × 10⁹/L)

Explanation: Answer reason: A new, progressive drop in blood pressure in a client with pericarditis raises concern for evolving cardiac tamponade, which can rapidly impair ventricular filling and cardiac output. This trend requires immediate bedside evaluation for additional tamponade findings (eg, tachycardia, JVD, muffled heart sounds, pulsus paradoxus) and urgent escalation for interventions. The atrial fibrillation with a rate of 122/min and the pneumonia leukocytosis indicate instability/infection but are generally less immediately life-threatening than a potential obstructive shock process.

The nurse on the neurotrauma unit receives report on 4 clients. Which client should the nurse assess first?

• Client in neurogenic shock from a spinal cord injury, with pulse of 56/min, blood pressure of 120/60 mm Hg, and warm and pink skin
• Client with a concussion from closed-head injury due to a fall, Glasgow Coma Scale score of 15, headache, and memory loss
• Client with a subdural hematoma, pulse of 48/min, blood pressure of 190/90 mm Hg, and a pupil that reacts slowly to light
• Client with central diabetes insipidus from a head injury, hypernatremia, and urine output of 210 mL/hr

Explanation: Answer reason: A subdural hematoma can expand or worsen edema, so new focal signs and vital-sign changes are treated as unstable until proven otherwise. The concussion client has a normal GCS and expected post-concussive symptoms, making them lower priority. Central diabetes insipidus with high urine output and hypernatremia is serious but typically allows brief time for targeted labs/therapy compared with signs of acute neurologic deterioration.

The nurse employed in an emergency department is assigned to triage clients coming to the emergency department for treatment on the evening shift. The nurse should assign priority to which client?

• A client complaining of muscle aches, a headache, and history of seizures
• A client who twisted her ankle when rollerblading and is requesting medication for pain
• A client with a minor laceration on the index finger sustained while cutting an eggplant
• A client with chest pain who states that he just ate pizza that was made with a very spicy sauce

Explanation: Answer reason: Chest pain can represent acute coronary syndrome and requires rapid assessment, vital signs, ECG, and timely intervention even if a benign explanation like reflux seems plausible. The other presentations (ankle sprain pain request, minor finger laceration) are lower acuity and typically stable. A headache with myalgias and a seizure history is concerning but does not indicate an active airway/breathing/circulation compromise as clearly as current chest pain, so it is not the top priority in triage without signs of an ongoing seizure or instability.

A nurse reports for duty and receives report on her clients for the day. After report is received which client should the nurse see first?

• The client with a DVT complaining of SOB after walking down the hall
• The client with stable angina complaining of SOB after walking down the hall
• The client with COPD complaining of SOB after walking down the hall
• The client who is morbidly obese complaining of SOB after walking down the hall

Explanation: Answer reason: Exertional dyspnea that newly appears after ambulation suggests an acute change in cardiopulmonary status rather than a chronic baseline symptom. Stable angina, COPD, and morbid obesity can cause exertional dyspnea, but these are generally expected patterns unless accompanied by acute instability signs. Prioritizing this client follows triage principles to see the highest risk for sudden deterioration first.

The night nurse on a medical floor has just received report. On which of the following clients should the nurse make rounds FIRST?

• The 52-year-old female with pancreatitis who is experiencing abdominal pain rated 4 on a 1–10 scale
• The 70-year-old male who underwent a transurethral resection of the prostate (TURP) yesterday and is having a burning sensation during urination
• The 78-year-old male with diagnosis of left-sided heart failure who has developed a new nonproductive cough and is restless
• The 37-year-old female diagnosed with cellulitis of the left leg yesterday who is experiencing redness and warmth of the left leg

Explanation: Answer reason: A new cough plus agitation/restlessness can be an early sign of declining oxygenation and impending respiratory distress, requiring prompt assessment of lung sounds, SpO2, and need for oxygen/diuretics. The other clients have expected or non-urgent findings (mild pancreatitis pain, dysuria after TURP often due to irritation, and localized cellulitis inflammation) that are less likely to decompensate quickly. Prioritizing the highest risk for rapid deterioration follows ABCs and acute change-from-baseline triage principles.

After receiving a change-of-shift report about these patients, which patient should the nurse assess first?

• A 31-year-old who has iatrogenic Cushing's syndrome with a capillary blood glucose level of 244 mg/dl
• A 53-year-old who has Addison's disease and is due for a scheduled dose of hydrocortisone (Solu-Cortef)
• A 22-year-old admitted with SIADH who has a serum sodium level of 130 mEq/L
• A 70-year-old who recently started levothyroxine (Synthroid) to treat hypothyroidism and has an irregular pulse of 134

Explanation: Answer reason: Excess thyroid hormone effect from levothyroxine (especially in older adults) can precipitate atrial fibrillation or other dangerous dysrhythmias, making immediate assessment of rhythm, blood pressure, symptoms, and need for urgent intervention the priority. A glucose of 244 mg/dL is elevated but not typically an immediate threat without symptoms of DKA/HHS. Mild hyponatremia in SIADH (130 mEq/L) and a scheduled steroid dose in stable Addison’s disease are important but generally less immediately life-threatening than an irregular pulse at 134.

The nurse in the pediatric clinic is triaging telephone messages. The nurse should call the parent of which child first?

• 2-year-old with bilateral tympanostomy tubes who has a small piece of plastic in the right outer ear
• 4-year-old post adenotonsillectomy who is now reporting ear pain
• 6-year-old with strep throat who needs a note to return to school 24 hours after starting antibiotics
• 7-year-old 5 days post tonsillectomy who wants to return to soccer practice today

Explanation: Answer reason: In triage, postoperative symptoms take priority over administrative requests or stable, minor problems because they can deteriorate quickly at home. A small plastic piece in the outer ear is typically non-urgent unless there is canal trauma, severe pain, or the object is deep/caustic. Return-to-school paperwork and return-to-sports questions are lowest acuity and can safely wait after urgent clinical concerns are addressed.

A nurse hears various alarms sounding from different client rooms. Which alarm will the nurse address first?

• Distal occlusion alarm on an infusion pump infusing heparin
• Low-pressure limit alarm on a ventilator
• Monitor alarm for a low respiratory rate of 11 breaths/min
• Occlusion alarm on a continuous enteral feeding pump

Explanation: Answer reason: This is an ABCs/airway-breathing emergency and must be assessed and corrected immediately (check patient first, then tubing/connections). A respiratory rate of 11/min can be normal for some adults and is less urgent than a potential ventilator disconnection. Occlusion alarms on heparin or enteral feeding pumps indicate interrupted therapy/flow but typically do not create the same immediate life-threatening risk as loss of ventilation.

The spouse brings a client to the emergency department due to erratic behavior and expressions of despair. The emergency department is extremely busy with many clients. When the triage nurse asks if the client feels suicidal now, the client shrugs the shoulders. What initial action should the triage nurse take?

• Ask the client to make a verbal contract to not harm self
• Document that the client is not currently suicidal
• Place the client in an inside hallway with one-on-one observation
• Return the client to the waiting room with the spouse

Explanation: Answer reason: In a busy ED, the priority is to prevent self-harm by ensuring continuous observation in a controlled, visible area while further assessment is performed. Safety contracts are not reliable and do not reduce suicide risk in an acute setting. Sending the client back to the waiting room or documenting “not suicidal” is unsafe because the client has not clearly denied intent and is demonstrating concerning behavior and despair.

The nurse has become aware of the following client situations. The nurse should first assess the client?

• Who had a right pneumonectomy 24 hours ago and is in the high-Fowler's position while lying on the right side
• With chronic obstructive pulmonary disease (COPD) who is using pursed-lip breathing and reporting hemoptysis
• Who had a wedge resection of the left lung 24 hours ago and is sitting in the high-Fowler's position
• With heart failure who has a productive cough and is restless

Explanation: Answer reason: Pursed-lip breathing may be a baseline COPD coping strategy, but new bleeding shifts this client into a potentially unstable status needing prompt evaluation of oxygenation, work of breathing, vital signs, and amount of blood. By comparison, the post-lung surgery positioning issues are important but are less immediately life-threatening if the client is otherwise stable, and the wedge resection client described is appropriately positioned. The heart failure client’s restlessness could indicate hypoxia, but hemoptysis is a more specific red-flag finding for sudden deterioration that should be assessed first.

The nurse has received report on 4 pediatric clients on a telemetry unit. Which client should the nurse assess first?

• Adolescent client with coarctation of the aorta and diminished femoral pulses
• Infant client with ventricular septal defect with reported grunting during feeding
• Newborn client with patent ductus arteriosus and a loud machinery-like systolic murmur
• Preschool client with tetralogy of Fallot who has finger clubbing and irritability

Explanation: Answer reason: With a VSD, pulmonary overcirculation can worsen during feeding and trigger acute respiratory distress and fatigue, requiring immediate assessment of respiratory status, oxygenation, and signs of heart failure. The other findings are more consistent with chronic or expected manifestations (diminished femoral pulses in coarctation, classic PDA murmur, finger clubbing in long-standing cyanotic disease) without an acute change described. In triage, the newest or most unstable respiratory symptom takes precedence over stable baseline cardiovascular findings.

The nurse is triaging clients in the emergency department. Which client needs to be seen first?

• 18-year-old female with fever, suprapubic pain, and dysuria
• 21-year-old male with diffuse abdominal pain and a rigid abdomen
• 64-year-old male with a pulsatile mass in the periumbilical area and back pain
• 75-year-old with nausea, fever, and left lower quadrant pain

Explanation: Answer reason: Triage prioritizes conditions with the highest risk of rapid deterioration and death over potentially serious but less immediately fatal problems. This client needs emergent assessment, hemodynamic monitoring, large-bore IV access, and rapid surgical/vascular evaluation. By comparison, symptoms consistent with UTI or diverticulitis typically allow a brief delay for evaluation, and even peritonitis signs require urgent care but are generally less instantly fatal than a suspected rupturing aneurysm.

A nurse working in the newborn nursery receives report on a group of newborn clients. Which client does the nurse assess first?

• 4 hours of age, 9 lb 15 oz at birth, whose glucometer reading was 45 mg/dL at 3 hours of age.
• 26 hours of age, born at 36 weeks' gestation, 3 hours post-circumcision, needs to breastfeed
• 3 hours of age, 7 lb 1 oz at birth, with a heart rate of 158 beats/min. and a respiratory rate of 56 breaths/min.
• 2 hours of age, born at 37 weeks' gestation, temperature of 97.6° F (36.44° C) after bath 30 minutes ago

Explanation: Answer reason: Neonatal hypoglycemia is an urgent physiologic risk because the newborn brain relies on glucose and low levels can rapidly progress to jitteriness, lethargy, seizures, and apnea if not recognized and treated. A large-for-gestational-age infant is at higher risk for hypoglycemia (often related to hyperinsulinemia), and a borderline/low point-of-care glucose requires prompt reassessment and intervention (feeding and repeat glucose, escalation if symptomatic or persistently low). The other findings are within expected transitional ranges for many newborns: HR 158 and RR 56 are normal, and a temperature of 97.6°F shortly after a bath is mildly low but typically addressed with warming measures and reassessment after immediate glucose concerns are ruled out. Post-circumcision feeding needs are important, but they are not as time-critical as a potentially deteriorating glucose level in a high-risk infant.

The nurse in the outpatient clinic is reviewing phone messages. Which client should the nurse call back first?

• Client post kidney transplant who reports white spots in the oral cavity
• Client with a history of mitral valve regurgitation who reports fatigue
• Client with erythema and purulent drainage at the site of a spider bite
• Client with hypertension who reports a cold and nasal congestion

Explanation: Answer reason: White oral plaques are consistent with opportunistic oral candidiasis, which can extend to esophagitis, impair intake, and signal broader immune compromise requiring prompt evaluation and treatment/medication adjustment. In contrast, fatigue in chronic valve disease is typically subacute unless accompanied by red-flag cardiopulmonary symptoms, and an inflamed draining bite site usually needs timely care but is less immediately high-risk than infection in a transplant recipient. Cold/nasal congestion in a client with hypertension is generally the lowest priority and can often be managed with education about safe OTC choices.

The registered nurse is triaging pediatric clients in the emergency department. Which client is a priority for diagnostic testing and definitive care?

• 4-year-old with right-sided abdominal mass reporting fatigue
• 5-year-old with chronic constipation reporting abdominal pain and no bowel movement for 2 days
• 10-year-old with sickle cell anemia reporting generalized pain of "10" and brownish urine
• 13-year-old with type 1 diabetes reporting nausea, vomiting, and abdominal pain

Explanation: Answer reason: These symptoms in a child with type 1 diabetes are classic red flags for diabetic ketoacidosis, a time-sensitive endocrine emergency requiring immediate labs (glucose, ketones, electrolytes, venous blood gas) and definitive treatment with IV fluids, insulin, and close monitoring. DKA can rapidly progress to severe dehydration, electrolyte derangements (especially potassium shifts), shock, and cerebral edema if care is delayed. While severe sickle cell pain needs prompt analgesia and evaluation, the presentation given does not signal an immediately life-threatening instability as strongly as suspected DKA. Constipation and an abdominal mass are concerning but are typically less acute than a potential metabolic crisis requiring emergent stabilization and diagnostics.

A triage nurse is in an emergency department when several hundred clients who were injured in a train collision arrive at the facility for treatment. The nurse should determine that which of the following clients requires immediate treatment?

• A client who has neck pain and was transported to the facility on a backboard
• A client who has epigastric and left-arm pain and is diaphoretic
• A client who has nasal and orbital ecchymosis and a respiratory rate of 16/min
• A client who has abdominal pain and is 2 months pregnant

Explanation: Answer reason: Epigastric discomfort with radiation to the left arm plus diaphoresis is a classic high-risk presentation of myocardial ischemia that can rapidly deteriorate into lethal dysrhythmias or cardiogenic shock without prompt evaluation and treatment. This client requires immediate ECG, oxygenation/monitoring, IV access, and time-sensitive therapies. In contrast, stable respirations with facial ecchymosis or isolated neck pain on immobilization suggests potential injury but not an immediately decompensating ABC problem in the absence of distress or neurologic compromise. Pregnancy with abdominal pain is concerning, but at 2 months gestation the uterus is still protected in the pelvis and the presentation is less immediately predictive of sudden collapse than active ischemia signs.

The nurse has received the following information about assigned clients who have had surgery within the past 8 hours. The nurse should first assess the client?

• With diabetes mellitus (type 1) who had debridement of a foot ulcer, is reporting feeling thirsty and has a blood glucose level of 160 mg/dL (8.8 mmol/L)
• Who had a pulmonary lobectomy, has tidaling in the water seal chamber of the closed-chest drainage system and has respirations of 20
• Who had transurethral resection of the prostate (TURP), has pink-tinged urine and has a blood pressure of 116/70 mm Hg
• With hyperthyroidism who had an inguinal hernia repair, is reporting feeling hot and has a pulse of 110

Explanation: Answer reason: Feeling hot with tachycardia shortly after surgery is an early warning pattern that warrants immediate assessment to identify fever, dysrhythmias, hypertension, and evolving decompensation. The lobectomy finding of tidaling with a respiratory rate of 20 is expected with a functioning chest tube and does not indicate urgent deterioration. Pink-tinged urine after TURP and mild thirst with a glucose of 160 mg/dL are common/less emergent postoperative findings compared with potential thyroid storm.

The nurse provides care for clients in the outpatient clinic and receives four phone calls. Which call does the nurse return first?

• A client reports a headache unrelieved by extra-strength acetaminophen doses every 4 hours for 2 days.
• A client reports ankle pain, swelling, and warmth. The client states there is no injury to the ankle.
• The parent of a toddler calls to report that their child has a rash and sore throat.
• The parent of a toddler calls to report that their child swallowed a nickel.

Explanation: Answer reason: Airway/breathing threats and time-sensitive ingestion risks are triaged first because a foreign body can obstruct the airway or lodge in the esophagus and rapidly deteriorate. A swallowed coin in a toddler requires immediate assessment for choking, drooling, stridor, respiratory distress, and prompt referral for urgent evaluation/imaging as indicated. The ankle swelling/warmth without injury could suggest DVT or infection and is concerning but is typically less immediately life-threatening than a potential airway-compromising ingestion. The headache and the rash with sore throat are important but generally allow for later follow-up unless additional red-flag symptoms are present.

A nurse working on a medical nursing unit during an external disaster is called to assist with care for clients coming into the hospital emergency department. Using principles of triage, the nurse initiates immediate care for a client with which of the following injuries?

• Bright red bleeding from a neck wound
• Penetrating abdominal injury
• Fractured tibia
• Open massive head injury in deep coma

Explanation: Answer reason: Bright red bleeding from a neck wound suggests arterial bleeding that can lead to exsanguination and loss of airway integrity within minutes, requiring instant hemorrhage control and airway management. A penetrating abdominal injury is serious but may be temporized if there is no immediate airway compromise or massive external bleeding. A fractured tibia is typically delayed, and an open massive head injury with deep coma is often categorized as expectant when resources are limited because the likelihood of survival is low.

The psychiatric inpatient unit has four new admissions. Which client does the nurse see first?

• A salesperson diagnosed with depression after the baby was born with Down syndrome and the spouse threatened to file for divorce.
• A police officer with a history of post-traumatic stress disorder (PTSD) and who was admitted with agoraphobia after two of his co-officers were killed.
• A computer programmer admitted with a diagnosis of generalized anxiety disorder and who has extensive debt and just filed for bankruptcy.
• A college student admitted for depression and anxiety after a sibling committed suicide and a parent was recently diagnosed with lung cancer.

Explanation: Answer reason: In psychiatric triage, the nurse prioritizes clients with the highest immediate safety risk, especially potential self-harm. Recent exposure to suicide in a close family member substantially increases suicide risk due to grief, contagion effects, and heightened access/ideation in vulnerable periods. Concurrent major stressors and depressive symptoms further elevate risk for acute deterioration, warranting first assessment for suicidal ideation, plan, means, and level of supervision needed. The other clients describe significant stress, anxiety, or PTSD features but do not include this strong, time-sensitive suicide-risk indicator.

After receiving report, which patient admitted to the emergency department should the nurse assess first?

• 67-year-old who has a gangrenous left foot ulcer with a weak pedal pulse
• 58-year-old who is taking anticoagulants for atrial fibrillation and has black stools
• 50-year-old who is complaining of sudden "sharp" and "worst ever" upper back pain
• 39-year-old who has right calf tenderness, redness, and swelling after a long plane ride

Explanation: Answer reason: In ED triage, patients with potential airway/breathing/circulation collapse and time-sensitive catastrophic diagnoses are assessed first because delays markedly increase mortality. Black stools on anticoagulants indicate probable GI bleeding and requires urgent evaluation, but it is often less immediately fatal than suspected aortic catastrophe unless there are signs of hemodynamic instability. Calf pain after a long flight suggests DVT and needs prompt treatment to prevent PE, but it is typically not as immediately unstable as suspected dissection; the gangrenous ulcer is serious but usually a slower-evolving threat unless septic or acutely ischemic.

The nurse receives the following client set: 50 year old male with Chest pain, 13 year old with asthma attack, 2 month old that is fussy and a 90 year old female with cyclical vomiting. Which client should the nurse see first?

• 13 year old with asthma attack
• 90 year old female with cyclical vomiting
• 2 month old that is fussy
• 50 year old male with Chest pain

Explanation: Answer reason: An acute asthma attack can progress quickly to severe bronchospasm, fatigue, and impending respiratory failure, making immediate assessment and intervention critical. Cyclical vomiting and fussiness may reflect discomfort or dehydration risk but are typically less immediately life-threatening than compromised ventilation. Chest pain is high priority, but without additional cues of instability (e.g., diaphoresis, hypotension, respiratory distress), the actively compromised breathing scenario is the most urgent to assess first.

The nurse has just received a change-of-shift report about these clients on the coronary step-down unit. Which one will the nurse assess first?

• A 26-year-old client with heart failure caused by congenital mitral stenosis who is scheduled for balloon valvuloplasty later today
• A 45-year-old client with constrictive cardiomyopathy who developed acute dyspnea and agitation about 1 hour before the shift change
• A 56-year-old client who underwent coronary angioplasty and stent placement yesterday and has reported occasional chest pain since the procedure
• A 77-year-old client who was transferred from the intensive care unit 2 days ago after coronary artery bypass grafting and has a temperature of 100.6°F (38.1°C)

Explanation: Answer reason: Constrictive cardiomyopathy limits ventricular filling; sudden symptoms may reflect worsening low cardiac output, pulmonary congestion, or another time-sensitive deterioration. By contrast, a scheduled valvuloplasty is planned care without acute instability, and a low-grade fever 2 days post-CABG is commonly monitored but is not as immediately life-threatening. Occasional post-stent chest pain warrants prompt evaluation, but the sudden onset dyspnea with agitation is the most urgent indicator of impending compromise.

A nurse is short-staffed because two people did not show up for work. Of the following four patients, which one would the nurse care for first?

• (a) A pt just admitted with acute abdominal pain and possible cholecystisis
• (b) A pt with nephritic syndrome with increasing edema; hourly urine and vital signs.
• (c) A confused pt yelling because he is in soft restraints and cannot get out of bed.
• (d) A head injury-patient with an IV who was just admitted to the unit.

Explanation: Answer reason: Initial triage prioritizes threats to airway, breathing, and circulation and conditions with high risk of rapid neurologic deterioration. A newly admitted head-injury patient requires immediate baseline neuro assessment (LOC, pupils, motor response), evaluation for rising ICP, and confirmation that IV access/fluids/meds are correctly ordered and running, because deterioration can be sudden and irreversible. The abdominal pain/possible cholecystitis and nephritic syndrome with edema are important but are typically less immediately life-threatening if currently stable and already being monitored. The confused restrained patient needs prompt safety checks and reassessment, but without evidence of airway/respiratory compromise or acute neurologic injury, this is a lower priority than a new head trauma admission.

The nurse has received a change of shift report on clients. Which client should the nurse assess first?

• A client with COPD with a PaO2 of 56 mm Hg who is being discharged home on oxygen
• A client with asthma with respirations of 36 breaths/min whose wheezing has diminished
• A client with asthma who has a heart rate of 90 bpm and whose beta-blocker is scheduled to be administered now
• A client who is scheduled for an angiogram now and is ready to be transported

Explanation: Answer reason: Severe tachypnea plus “diminished wheezing” can indicate markedly reduced airflow (“silent chest”) as bronchospasm worsens and fatigue develops, which is more dangerous than audible wheezing. This client needs immediate assessment for work of breathing, oxygenation, mental status changes, and rapid escalation to bronchodilators, steroids, oxygen, and possible ventilatory support. By comparison, a stable COPD patient being discharged on oxygen and a ready-for-transport angiogram patient are not as immediately life-threatening in the moment.

The home-health nurse is assigned to the following clients who live within 3 miles (4.8 km) of one another. The nurse should first see the?

• 18-month-old client with bronchopulmonary dysplasia (BPD) who is receiving oxygen via nasal cannula at 1.5 L/min and has vomited 4 times in the past 24 hours
• 4-year-old client with cerebral palsy who is receiving continuous tube feedings at 60 mL/hr and has a temperature of 100.8° F (38.2° C)
• 6-year-old client with acute lymphoid leukemia (ALL) who has a white blood cell (WBC) count of 3,000/cu mm (3 × 10^9/L) and ulcerated lesions in the mouth
• 10-year-old client with nephrotic syndrome who has 2+ proteinuria and periorbital edema

Explanation: Answer reason: 4-year-old client with cerebral palsy who is receiving continuous tube feedings at 60 mL/hr and has a temperature of 100.8° F (38.2° C) Prioritization in home care uses ABCs and risk of rapid deterioration, with special attention to aspiration and sepsis risk. Fever in a child receiving continuous enteral feeds suggests possible aspiration pneumonia, feeding intolerance, or other infection that can quickly compromise airway and breathing, requiring prompt assessment and potential holding feeds. The BPD client’s vomiting is concerning for dehydration/aspiration but is not accompanied by new respiratory distress data and is lower acuity than an active febrile child on tube feeds. The ALL client is leukopenic with mucositis but has no fever given (infection is possible yet not demonstrated as urgent in the stem), and the nephrotic syndrome findings are expected/ongoing unless severe respiratory compromise or infection signs are present.

A nurse is assigned to multiple clients. Which client should the nurse reassess as a priority after administering IV morphine for pain relief?

• 67-year-old with pancreatitis admitted for acute pain
• 30-year-old with pneumonia reporting sharp right side chest pain on deep inspiration
• 45-year-old who is 1-day postoperative gastric surgery reporting pain at the incision site
• 65-year-old with obstructive sleep apnea reporting pain at the fracture surgery site.

Explanation: Answer reason: IV morphine can cause dose-dependent respiratory depression, and patients with obstructive sleep apnea have reduced baseline airway patency and higher sensitivity to opioid-induced hypoventilation. Prioritization after opioid administration focuses on airway and breathing risks (RR, depth, sedation level, and SpO2), making this client highest risk for rapid deterioration. The other clients still require reassessment for pain control and adverse effects, but they do not carry the same immediate, predictable vulnerability to opioid-related ventilatory compromise. Early recognition of oversedation and hypoventilation in this high-risk client prevents respiratory arrest and the need for emergency reversal.

Which virus causes AIDS (Acquired Immune Deficiency Syndrome)?

• HIV
• HPV
• Hepatitis B
• Influenza

Explanation: Answer reason: This mechanism explains the hallmark susceptibility to opportunistic infections and certain malignancies. HPV is primarily associated with anogenital warts and cervical and other cancers, not systemic CD4 depletion. Hepatitis B primarily causes liver disease, and influenza causes acute respiratory infection; neither produces the progressive acquired immunodeficiency that defines AIDS.

Which disease is caused by the bacterium Vibrio cholerae?

• Cholera
• Typhoid
• Dysentery
• Malaria

Explanation: Answer reason: Vibrio cholerae colonizes the small intestine and produces cholera toxin, which drives massive chloride and water secretion, leading to profuse watery diarrhea and dehydration. This clinical syndrome is the disease cholera. Typhoid is caused by Salmonella Typhi, dysentery is classically due to Shigella or Entamoeba histolytica, and malaria is due to Plasmodium protozoa transmitted by Anopheles mosquitoes.

Which disease is caused by the Plasmodium parasite?

• Malaria
• Dengue
• Typhoid
• Tuberculosis

Explanation: Answer reason: This life cycle produces the characteristic febrile paroxysms and can cause anemia, jaundice, and severe complications such as cerebral involvement with certain species. Dengue is caused by a flavivirus, typhoid by Salmonella Typhi, and tuberculosis by Mycobacterium tuberculosis, so they do not match a Plasmodium etiology. Therefore the only option directly caused by Plasmodium is the one selected.

A sexually transmitted disease caused by bacteria is ...?

• Leprosy
• AIDS
• Syphilis
• Pertussis

Explanation: Answer reason: Syphilis is caused by the spirochete Treponema pallidum, making it a classic bacterial STD. AIDS is caused by HIV (a virus), so it is not bacterial. Leprosy (Mycobacterium leprae) and pertussis (Bordetella pertussis) are bacterial diseases but are not primarily sexually transmitted.

Acid-fast staining is used for identification of which bacteria?

• Staphylococcus
• Mycobacterium
• Streptococcus
• Salmonella

Explanation: Answer reason: Mycobacteria have high mycolic acid content, making them classically acid-fast and identifiable with Ziehl-Neelsen or Kinyoun stains. In contrast, Staphylococcus and Streptococcus are identified primarily by Gram stain and related biochemical tests because they do not have mycolic-acid–rich walls. Salmonella is a Gram-negative bacillus and is not acid-fast, so it would not be targeted by this staining method.

The most common mode of transmission of TB is?

• Fecal–oral route
• Droplet infection
• Sexual contact
• Direct skin contact

Explanation: Answer reason: These particles can remain suspended and be inhaled by others, making respiratory spread the dominant route. Fecal–oral transmission is typical of enteric pathogens, not Mycobacterium tuberculosis. Direct skin contact and sexual contact are not common mechanisms for TB spread in routine community transmission.

Which bacterium causes whooping cough?

• Bordetella pertussis
• Haemophilus influenzae
• Neisseria meningitidis
• Corynebacterium diphtheriae

Explanation: Answer reason: The organism responsible is a small gram-negative coccobacillus that adheres to ciliated respiratory epithelium and disrupts mucociliary clearance. The other options are associated with different syndromes: Haemophilus influenzae with otitis media/epiglottitis (type b historically), Neisseria meningitidis with meningitis/septicemia, and Corynebacterium diphtheriae with pseudomembranous pharyngitis and systemic toxin effects. Therefore the best match for the etiology of pertussis is the first option.

Which fungus is associated with tinea versicolor?

• Malassezia furfur
• Trichophyton rubrum
• Candida albicans
• Epidermophyton floccosum

Explanation: Answer reason: This organism’s yeast form on KOH classically shows “spaghetti and meatballs” (hyphae with spores), supporting its role in this condition. Dermatophytes such as Trichophyton rubrum and Epidermophyton floccosum primarily cause tinea corporis/pedis/cruris by invading keratinized tissues, not tinea versicolor. Candida albicans more commonly causes mucocutaneous candidiasis (thrush, intertrigo) rather than the pigmentary changes typical of tinea versicolor.

Which fungus is associated with candidiasis?

• Candida albicans
• Sporothrix schenckii
• Aspergillus fumigatus
• Rhinosporidium seeberi

Explanation: Answer reason: The organism most classically responsible for thrush, vulvovaginal candidiasis, and cutaneous/intertriginous yeast infections is this commensal yeast, especially with antibiotic use, diabetes, or immunosuppression. In contrast, Sporothrix schenckii causes lymphocutaneous sporotrichosis after traumatic inoculation from plants/soil, not candidiasis. Aspergillus fumigatus is associated with invasive aspergillosis or allergic bronchopulmonary disease rather than mucocutaneous yeast infections.

Which organism is most commonly associated with peptic ulcer disease?

• Helicobacter pylori
• Escherithia coli
• Staphylococcus aureus
• Vibrio cholerae

Explanation: Answer reason: This organism colonizes the stomach lining (via urease activity and motility), causing inflammation and predisposing to duodenal and gastric ulcers. The other listed bacteria are classically associated with different syndromes (e.g., watery diarrhea with cholera, skin/soft tissue and toxin-mediated disease with staphylococci), not ulcer formation. Identifying the correct pathogen matters clinically because eradication therapy significantly reduces ulcer recurrence and complications like bleeding.

Patient has been diagnosed with a urinary tract infection. What is the most likely cause of this infection?

• Staphylococcus aureus
• Neisseria gonorrhoeae
• Escherichia coli enterococci
• Streptococcus beta-hemolytic A or B

Explanation: Answer reason: E. coli is the predominant uropathogen because its adhesins (e.g., P fimbriae) promote attachment to uroepithelium and persistence despite urine flow. Enterococci are also recognized causes of UTIs, particularly in healthcare-associated settings, making this combined option the best match among the choices. Neisseria gonorrhoeae primarily causes urethritis/cervicitis rather than typical cystitis, and beta-hemolytic streptococci and Staphylococcus aureus are less common primary causes of uncomplicated UTIs.

Fever, whooping cough, bod, ache are the clinical features of-?

• Diphtheria
• Pertusis
• Measles
• Mumps

Explanation: Answer reason: The distinctive whoop is the key discriminator among the listed vaccine-preventable diseases. Diphtheria more typically presents with sore throat and a gray pseudomembrane, not a classic whoop. Measles and mumps have hallmark features such as rash/Koplik spots or parotitis, respectively, rather than whooping paroxysms.

Which of the following spreads through contaminated food or water?

• Tetanus
• Cholera
• Rabies
• Tuberculosis

Explanation: Answer reason: Vibrio cholerae is acquired through ingestion of contaminated water/food and can rapidly cause severe dehydration due to toxin-mediated fluid loss. In contrast, tetanus results from wound contamination with spores, rabies is transmitted via animal bites/saliva, and tuberculosis spreads primarily through airborne droplet nuclei. Therefore the only option matching food/water transmission is the correct one.

A 40-year-old man with AIDS and a CD4 count of 80/mm3 has a fever and a right lower lobe infiltrate. Which of the following organisms would be considered to be the most likely cause of his pneumonia if recovered from BAL fluid (bronchoalveolar lavage)?

• Cytomegalovirus
• Herpes simplex
• Legionella
• Enterobacter cloacae
• Candida albicans

Explanation: Answer reason: Legionella is a recognized cause of severe pneumonia in immunocompromised patients and is classically diagnosed from lower respiratory specimens (including BAL) using culture on specialized media or antigen/PCR. Cytomegalovirus can be detected in BAL but often represents colonization/reactivation rather than the primary cause of a focal lobar pneumonia; true CMV pneumonitis is typically diffuse/interstitial with hypoxemia. Candida in respiratory samples is usually colonization, and HSV pneumonia is uncommon and usually in critically ill/intubated patients, making them less likely primary causes here.

What is the most common cause of bacterial vaginosis?

• Gardnerella vaginalis
• Escherichia coli
• Staphylococcus aureus
• Streptococcus pneumoniae

Explanation: Answer reason: The organism most commonly associated with this dysbiosis in exam questions is Gardnerella vaginalis, which correlates with clue cells and a fishy (amine) odor. Escherichia coli is a common uropathogen and can cause some genital infections but is not the typical cause of BV. Staphylococcus aureus and Streptococcus pneumoniae are not characteristic vaginal pathogens for BV and are more associated with skin/soft tissue and respiratory infections, respectively.

What is the most common cause of meningitis in adults?

• Streptococcus pneumoniae
• Neisseria meningitidis
• Escherichia coli
• Haemophilus influenzae

Explanation: Answer reason: pneumoniae due to its frequent nasopharyngeal colonization and invasive potential, especially in older adults and those with comorbidities or asplenia. This organism commonly causes otitis media/sinusitis and pneumonia that can seed the meninges hematogenously. N. meningitidis is also important in adolescents/young adults and outbreak settings, but overall it is typically less common than pneumococcus in adults. E. coli is more characteristic of neonatal meningitis, and H. influenzae has markedly decreased in vaccinated populations and is more associated with pediatric disease.

Influenza disease is caused by which of the following?

• Bacteria
• Virus
• Fungi
• Protozoa

Explanation: Answer reason: The causative agent is identified by the disease’s transmission pattern (droplet/airborne-range exposure) and typical viral syndrome features such as abrupt fever, myalgias, and cough. Bacteria are more associated with secondary complications (e.g., bacterial pneumonia) rather than the primary cause of influenza. Fungi and protozoa do not cause the classic seasonal influenza illness.

Which bacterium is the most common cause of traveler’s diarrhea?

• Enterotoxigenic Escherichia coli
• Salmonella typhi
• Shigella sonnei
• Vibrio cholerae

Explanation: Answer reason: This mechanism leads to acute, noninflammatory diarrhea without prominent fever or blood, matching the classic presentation in travelers. By contrast, Salmonella typhi is associated with systemic enteric fever, Shigella more often causes inflammatory dysentery with blood/tenesmus, and Vibrio cholerae classically causes profuse “rice-water” stools but is not the most common overall cause of traveler’s diarrhea. Therefore, the organism most frequently implicated is the enterotoxigenic strain of E. coli.

Which of the following is a fungal disease?

• Cholera
• Ringworm
• Typhoid
• Tuberculosis

Explanation: Answer reason: This condition is commonly termed tinea and is transmitted by direct contact with infected people, animals, or fomites. By contrast, cholera and typhoid are bacterial enteric infections, and tuberculosis is a bacterial infection caused by Mycobacterium tuberculosis. Therefore, the only fungal disease listed is the dermatophyte infection.

Which disease is caused by the bacterium Mycobacterium tuberculosis?

• Malaria
• Tuberculosis
• AIDS
• Cancer

Explanation: Answer reason: Mycobacterium tuberculosis is an acid-fast bacillus that causes a chronic granulomatous infection most commonly involving the lungs, with potential for extrapulmonary spread. Malaria is caused by Plasmodium species (a protozoan), while AIDS is caused by HIV (a virus), so those do not match the bacterial organism given. Cancer is not caused by this bacterium, though chronic infections can be associated with malignancy risk in other contexts.

Which disease is caused by a 20–35 cm parasite, affecting intestines and treated with mebendazole?

• Ascariasis
• Filariasis
• Malaria
• Amebiasis

Explanation: Answer reason: Ascariasis is caused by the intestinal roundworm Ascaris lumbricoides, an adult helminth commonly measuring roughly 20–35 cm and living in the small intestine. Mebendazole is a first-line benzimidazole anthelmintic for intestinal nematode infections, including ascariasis, by inhibiting microtubule formation and glucose uptake in the worm. Filariasis involves tissue/lymphatic nematodes rather than a large intestinal adult worm and is typically treated with agents like diethylcarbamazine or ivermectin depending on the species. Malaria is a protozoal blood infection treated with antimalarials, and amebiasis is due to Entamoeba histolytica treated with metronidazole plus a luminal agent, not mebendazole.

Which bacteria causes peptic ulcer disease?

• Coli
• Salmonella
• Helicobacter pylori
• Shigella

Explanation: Answer reason: Peptic ulcer disease is most commonly caused by chronic gastric infection with a urease-producing organism that survives in acidic environments and disrupts mucosal defenses. This bacterium induces inflammation and increases vulnerability to acid injury, leading to gastric or duodenal ulceration. The other listed organisms more typically cause infectious gastroenteritis or dysentery rather than chronic ulcer formation. Clinically, identifying this cause matters because eradication with combination antibiotic therapy plus acid suppression reduces recurrence and complications such as bleeding.

Which organism is the most common cause of urinary tract infections?

• Escherichia coli
• Staphylococcus aureus
• Pseudomonas aeruginosa
• Klebsiella pneumoniae

Explanation: Answer reason: This organism is the predominant uropathogen due to its adhesins (fimbriae) that facilitate attachment to uroepithelial cells and persistence in the urinary tract. The other listed organisms can cause UTIs but are less common overall and are more associated with specific contexts (e.g., instrumentation, healthcare exposure, or complicated infections). Therefore the best single answer for the most common cause is the enteric organism listed.

Majority of animal-viruses contain?

• RNA and DNA
• RNA
• DNA
• None of the above

Explanation: Answer reason: In animal virology, RNA viruses are more numerous than DNA viruses, and many medically important animal viruses (e.g., orthomyxo-, paramyxo-, flavi-, retroviruses) have RNA genomes. Therefore the best general statement about the majority of animal viruses is that they contain RNA. The option claiming both RNA and DNA is incorrect because dual-genome viruses do not occur in standard human/animal virology.

The intermediate host of Leishmania donovani is?

• Dragonfly
• Anopheles mosquito
• Sandfly
• Tsetse fly

Explanation: Answer reason: The female phlebotomine sandfly ingests amastigotes during a blood meal and supports maturation in its gut before inoculating promastigotes into the next human host. Anopheles mosquitoes transmit Plasmodium (malaria), not Leishmania. Tsetse flies are vectors for Trypanosoma brucei (African trypanosomiasis), making them a common distractor but incorrect here.

What is the process by which organisms become resistant to antibiotics?

• Mutation
• Natural selection
• Genetic drift
• Antibiotic resistance

Explanation: Answer reason: Susceptible bacteria are killed or inhibited, while resistant ones persist and become a larger proportion of the population over time. Mutations can generate resistance genes, but the population-level increase in resistance is driven by selection. Genetic drift is random change and is not the primary mechanism for predictable resistance emergence in the presence of antibiotics.

BCG Vaccine is used to Protect against which disease?

• Tuberculosis
• Tetanus
• Diphtheria
• Whooping cough

Explanation: Answer reason: It is most effective at preventing severe childhood forms such as miliary TB and TB meningitis rather than reliably preventing adult pulmonary disease. Tetanus protection comes from tetanus toxoid (part of DTaP/Tdap), and diphtheria and pertussis are covered by diphtheria toxoid and acellular pertussis vaccines. Therefore, the vaccine in question corresponds to protection against TB.

The DPT vaccine is used to prevent which of the following diseases?

• Dengue, Pneumonia, Typhoid
• Diphtheria, Pertussis, Tetanus
• Diarrhea, Polio, Tetanus
• Diphtheria, Polio, Typhoid

Explanation: Answer reason: DPT is a combination vaccine containing diphtheria toxoid, pertussis antigen, and tetanus toxoid, providing protection against these three infections. Therefore the option listing those exact three diseases matches the vaccine’s intended coverage. Options including polio, typhoid, dengue, pneumonia, or nonspecific “diarrhea” describe illnesses targeted by other vaccines or causes and are not covered by DPT.

Rotavirus vaccine is used to prevent which disease?

• Polio
• Diarrhoea
• AIDS
• Hepatitis

Explanation: Answer reason: The vaccine is designed to prevent rotavirus infection and thereby reduce severe diarrheal disease and related hospitalizations. Polio, AIDS (HIV), and hepatitis are caused by different viruses and require different vaccines or preventive strategies. A common distractor is hepatitis, but rotavirus primarily targets the intestinal tract rather than the liver.

Which skin condition is caused by a mite and is characterized by intense itching, especially at night?

• Tinea
• Scabies
• Herpes Zoster
• Impetigo

Explanation: Answer reason: The hallmark symptom is severe itching that often worsens at night, frequently accompanied by burrows and papules in characteristic locations (e.g., finger webs, wrists, waistline). Dermatophyte infections (tinea) are fungal rather than mite-related and typically cause annular scaling lesions, not the classic night-worse pruritus. Herpes zoster is a viral reactivation causing dermatomal pain and vesicles, and impetigo is a bacterial superficial infection with honey-colored crusts.

Which of the following is a characteristic of prokaryotic cells?

• Presence of a nucleus
• Presence of mitochondria
• Lack of membrane-bound organelles
• Presence of chloroplasts

Explanation: Answer reason: Their genetic material is located in a nucleoid region rather than enclosed within a true nucleus. Energy-generating processes occur at the cell membrane because they do not have mitochondria. Chloroplasts are also membrane-bound organelles and are found in photosynthetic eukaryotes, not prokaryotes.

Dengue is caused by Flavivirus. What is the vector of dengue fever?

• Aedes Mosquito
• Female Anopheles mosquito
• Male Anopheles mosquito
• Culex mosquito

Explanation: Answer reason: Dengue virus is classically transmitted by Aedes species mosquitoes (notably Aedes aegypti and Aedes albopictus), which bite during daytime and breed in clean, stagnant water around homes. Anopheles mosquitoes are primarily associated with malaria transmission, making them a common distractor here. Culex mosquitoes are more associated with infections like West Nile and Japanese encephalitis rather than dengue.

What is the term for a symbiotic relationship where one organism benefits and the other is neither helped nor harmed?

• Mutualism
• Commensalism
• Parasitism
• Competition

Explanation: Answer reason: Symbiosis can be categorized by how each organism is affected in terms of benefit or harm. When one organism gains an advantage (e.g., food, transport, shelter) while the other experiences no meaningful effect, the interaction is defined as commensalism. Mutualism differs because both organisms benefit, and parasitism differs because one benefits at the expense of the other. Competition is not a symbiotic relationship; it describes organisms vying for the same limited resource, typically disadvantaging both.

What is the term for a symbiotic relationship where one organism benefits while the other is neither helped nor harmed?

• Mutualism
• Parasitism
• Commensalism
• Competition

Explanation: Answer reason: This matches the stem’s “benefits” versus “neither helped nor harmed” description. Mutualism would require both organisms to benefit, while parasitism requires one to benefit at the expense of harm to the other. Competition is not a symbiotic relationship and implies both organisms are negatively affected by resource limitation.

The nurse cares for a client with type I diabetes mellitus. Which action, by the nurse, best assesses the chronic complication of neuropathy?

• Assess ability to feel the client and walk (5%)
• Check sensation in fingers and toes (73%)
• Inspect extremities for diabetic ulcers (12%)
• Take the blood pressure sitting and standing (10%)

Explanation: Answer reason: Bedside assessment focuses on detecting diminished light touch, temperature, vibration, or monofilament sensation in distal digits, which directly evaluates this complication. Inspecting for ulcers screens for skin breakdown that results from neuropathy but does not assess the neurologic deficit itself. Orthostatic blood pressures assess autonomic neuropathy, but the question most directly targets peripheral sensory neuropathy assessment.

The nurse is evaluating the effectiveness of antimicrobial therapy for a client diagnosed with infective endocarditis. The nurse determines that which finding is the least reliable indicator of effectiveness?

• Clear breath sounds
• Systolic heart murmur
• Temperature of 98.8° F
• Negative blood cultures

Explanation: Answer reason: A murmur may persist despite effective antibiotics because it can result from residual structural valve damage or regurgitation that does not resolve with eradication of infection. In contrast, defervescence and especially sterilization of blood cultures more directly indicate antimicrobial success. Clear breath sounds can be supportive but are less specific than culture clearance; however, a murmur is particularly unreliable because it may remain unchanged even when therapy is working.

In the early postoperative period, the nurse notes a bright red, 3" × 5" area of drainage on the client’s abdominal laparotomy dressing. What should be the nurse’s first action in response to this observation?

• Ignore it because drainage is normal.
• Increase the I.V. flow rate.
• Take the client’s vital signs.
• Change the dressing.

Explanation: Answer reason: Bright red drainage early post-op can indicate active bleeding, so the priority is to rapidly assess for hemodynamic instability. Checking vital signs evaluates for early hypovolemia/shock (tachycardia, hypotension, decreasing oxygen saturation) and guides urgency of escalation. Changing the dressing can obscure the amount and rate of bleeding and delays assessment; the dressing should typically be reinforced/marked after assessment per protocol. Increasing IV fluids may be needed later, but it is not the first step before confirming instability and notifying the provider.

Which of the following information would NOT be included in a client's pain history?

• The client's affective responses to pain
• The client's past alleviating measures
• The client's current vital signs
• The client's meaning of pain

Explanation: Answer reason: A pain history focuses on the subjective pain experience and its context, including quality, triggers, relieving factors, and the psychosocial meaning of the symptom. Vital signs are objective physiologic data collected during assessment, but they are not part of the historical narrative of pain and are unreliable as a primary indicator of pain severity. Affective responses and what the pain means to the client help characterize emotional and cognitive dimensions that shape coping and reporting. Prior alleviating measures are essential historical data because they guide what has or has not worked and inform the care plan.

A client with a history of heart failure visits the clinic. He states, “I have not been feeling like my old self for about 2 weeks.” It would be MOST important for the nurse to ask which of the following questions?

• “Do your ankles swell at the end of the day?”
• “Where do you sleep at night?”
• “How do you feel after you eat dinner?”
• “Do you have chest pain when you inhale?”

Explanation: Answer reason: Worsening heart failure commonly causes orthopnea and paroxysmal nocturnal dyspnea due to fluid redistribution and pulmonary congestion when lying flat. Asking about sleeping position (e.g., needing extra pillows or sleeping in a chair) quickly screens for decompensation and guides urgency of evaluation and therapy. Peripheral edema can support volume overload but may be less sensitive and can appear later than nocturnal symptoms. Pleuritic chest pain is not a typical heart-failure symptom pattern and would point more toward alternate diagnoses such as pulmonary or pleural inflammation.

The nurse performs a respiratory assessment on the client in for a yearly check up. What normal finding does the nurse expect to find on the client during the respiratory assessment?

• Tactile fremitus palpated over anterior sternum at 2nd intercostal space.
• Inspirations twice as long as expirations auscultated between scapulae.
• Auscultated bilateral lower lobe expirations twice the length of inspiration.
• Anterior-posterior diameter of chest equal to transverse diameter of chest.

Explanation: Answer reason: Normal vesicular breath sounds heard over peripheral lung fields have a longer inspiratory phase than expiratory phase (I:E about 3:1), but the expiratory phase can be longer in the dependent lower lobes while remaining soft and without adventitious sounds. This option best reflects an expected I:E relationship in a healthy adult assessment when auscultating lower lobes. By contrast, normal inspiration is not typically twice as long as expiration between the scapulae, where bronchovesicular sounds have a more equal I:E ratio. Equal anterior-posterior and transverse chest diameters suggests barrel chest (e.g., COPD), not a normal finding, and tactile fremitus is not typically assessed as a discrete “normal” over the anterior sternum at a specific intercostal space.

The nurse is performing a physical assessment on a patient with congestive heart failure (CHF). The nurse notes pitting edema and documents it as 2+ edema. Which of the following descriptions best defines 2+ edema?

• Barely detectable impression, immediate rebound
• Deeper indentation, 30 seconds to rebound
• Greater than 30 seconds to rebound
• Slight indentation, 15 seconds to rebound

Explanation: Answer reason: A 2+ finding corresponds to a mild-to-moderate pit with a brief but noticeable delay in rebound, commonly around 10–15 seconds. Findings that are barely detectable with immediate rebound align with 1+ edema, while deeper pits with longer rebound times indicate more severe edema (3+ to 4+). In CHF, accurate grading helps trend fluid overload and evaluate response to diuretics and other therapies.

A nurse notes a client’s respiratory rate is 24 breaths/min. on 3 L/min. of oxygen. The client reports shortness of breath. Which action does the nurse perform first?

• Administer a bronchodilator as prescribed.
• Conduct a respiratory assessment.
• Increase the oxygen flow rate.
• Notify the health care provider.

Explanation: Answer reason: Nursing priority follows ABCs, but the first action is to quickly assess the airway and breathing status to determine severity and the most appropriate immediate intervention. A focused respiratory assessment (work of breathing, lung sounds, SpO2 trend, mental status, ability to speak, accessory muscle use) identifies whether this is bronchospasm, fluid overload, atelectasis, or another cause. Automatically increasing oxygen without assessing can delay recognizing problems like worsening obstruction or impending fatigue and may not address the underlying issue. After assessment, the nurse can implement appropriate measures (e.g., administer ordered bronchodilator, titrate oxygen per protocol, and escalate/notify the provider based on findings).

The nurse is testing the extraocular movements in a client to assess for muscle weakness in the eyes. The nurse should implement which assessment technique to assess for muscle weakness in the eye?

• Test the corneal reflexes.
• Test the 6 cardinal positions of gaze.
• Test visual acuity, using a Snellen eye chart.
• Test sensory function by asking the client to close the eyes and then lightly touching the forehead, cheeks, and chin.

Explanation: Answer reason: Extraocular muscle weakness is assessed by evaluating coordinated eye movements controlled by cranial nerves III, IV, and VI. Having the client follow an object through the six cardinal fields systematically tests each extraocular muscle for weakness, limitation, or nystagmus. Corneal reflex testing mainly evaluates CN V and VII and does not assess extraocular muscle strength. Snellen testing assesses visual acuity, and facial light-touch testing evaluates CN V sensory function, neither of which directly measures extraocular motor function.

The nurse is closely monitoring the intake and output of an infant with heart failure who is receiving diuretic therapy. The nurse should use which most appropriate method to assess the urine output?

• Weighing the diapers
• Inserting a urinary catheter
• Comparing intake with output
• Measuring the amount of water added to formula

Explanation: Answer reason: This method is noninvasive and provides objective data needed to evaluate diuretic response and fluid balance in heart failure. Urinary catheterization is invasive and increases infection risk, so it is not the most appropriate routine method. The other choices do not directly measure urine volume and therefore cannot provide precise output assessment.

A school-aged client with cerebral palsy and a do not resuscitate status is treated for pneumonia at home. What is the home care nurse's first intervention when providing care?

• Administer nebulizer treatments.
• Assess the client's respiratory status.
• Document the client's respiratory status.
• Review any new prescriptions.

Explanation: Answer reason: Initial nursing care follows the assessment-first principle to establish current severity and detect urgent complications (e.g., increased work of breathing, hypoxia) before implementing interventions. Pneumonia in a child with cerebral palsy increases risk for ineffective airway clearance and rapid respiratory decline, so obtaining baseline findings (rate, effort, breath sounds, oxygenation, cough effectiveness) guides safe next steps. Treatments like nebulizers are implemented after confirming indications and prioritizing airway/breathing needs based on assessment findings. Documentation is essential but occurs after assessment, and reviewing prescriptions does not replace evaluating immediate physiologic status in the home setting.

A nurse assesses the fetal monitor of a client in labor. Which observation is most concerning to the nurse?

• The fetal heart rate is 164 beats/min.
• The fetal heart rate decelerates at the beginning of the contraction.
• The fetal heart rate decelerates at the end of the contraction.
• The fetal heart rate accelerates periodically for up to 60 seconds.

Explanation: Answer reason: Late decelerations (nadir after the peak of the contraction, occurring toward the end) reflect uteroplacental insufficiency and impaired fetal oxygenation, making them the most ominous tracing finding listed. This pattern indicates the fetus may be developing hypoxemia/acidemia, requiring prompt intrauterine resuscitation and escalation as needed. By contrast, decelerations that begin with the contraction are typically early decelerations from fetal head compression and are usually benign. Brief accelerations up to 60 seconds generally indicate adequate fetal oxygenation and intact neurologic responsiveness; a baseline of 164 bpm is mild tachycardia and can be less urgent unless persistent with other nonreassuring features.

A nurse assesses a client with pneumonia for bronchophony. The nurse uses what procedure?

• Ask the client to whisper a phrase while auscultating the lungs.
• Have the client say a long E sound while auscultating the lungs.
• Have the client say “ninety-nine” while auscultating the lungs.
• Have the client say “ninety-nine” while placing the palms on the chest wall.

Explanation: Answer reason: Bronchophony is assessed by having the patient speak clearly while the nurse auscultates lung fields to evaluate increased transmission of voice sounds through consolidated lung tissue. Pneumonia can cause consolidation, which makes spoken words sound louder and more distinct through the stethoscope than expected. Whispering assesses whispered pectoriloquy, and saying a long “E” assesses egophony, so those are different voice-transmission tests. Placing the palms on the chest wall while the client speaks evaluates tactile fremitus, which is palpation rather than auscultation.

Which of the following is an example of data that should be validated?

• The client states that he/she feels feverish; you measure the oral temperature at 98°F.
• The urinalysis report indicates there are white blood cells in the urine.
• The client has clear breath sounds; you count a respiratory rate of 18.
• The chest x-ray report indicates the client has pneumonia in the right lower lobe.

Explanation: Answer reason: Validation is required when assessment data are inconsistent, subjective, or don’t match objective findings, because decisions based on inaccurate cues can lead to inappropriate care. Feeling “feverish” is subjective and conflicts with an objectively normal oral temperature, so the nurse should recheck technique, consider other routes (e.g., tympanic/rectal), and reassess for other signs of infection. Laboratory and imaging reports are objective sources that generally do not require validation unless results are unexpected or don’t fit the clinical picture. A normal respiratory rate with clear breath sounds is internally consistent and does not suggest a need for validation.

Kris with a history of chronic infection of the urinary system complains of urinary frequency and burning sensation. To figure out whether the current problem is of renal origin, the nurse should assess whether the client has discomfort or pain in the?

• Urinary meatus
• Pain in the labium
• Suprapubic area
• Right or left costovertebral angle

Explanation: Answer reason: Bladder/urethral infections more often cause dysuria, frequency, and suprapubic discomfort rather than CVA tenderness. Assessing for CVA tenderness helps differentiate possible pyelonephritis or renal pathology from lower tract cystitis/urethritis. Findings limited to the urinary meatus or external genital discomfort suggest local irritation or urethral/vulvar causes, not renal origin.

The nurse notes an isolated premature ventricular contraction (PVC) on the cardiac monitor of a client recovering from anesthesia. Which action should the nurse take?

• Prepare for defibrillation.
• Continue to monitor the rhythm.
• Prepare to administer lidocaine hydrochloride.
• Notify the primary health care provider immediately.

Explanation: Answer reason: An isolated PVC in a stable post-anesthesia client is commonly transient and can occur with stimulation, hypoxia, pain, or electrolyte shifts; the immediate nursing priority is ongoing assessment for frequency, patterns (e.g., runs), and hemodynamic impact. Monitoring allows the nurse to correlate the rhythm with vital signs, oxygenation, symptoms, and triggers and to intervene if ectopy becomes frequent or the client destabilizes. Defibrillation is reserved for shockable lethal rhythms (e.g., ventricular fibrillation/pulseless VT) rather than a single PVC. Antiarrhythmic therapy or urgent provider notification is typically indicated when PVCs are frequent/multifocal, occur in runs, or are accompanied by chest pain, hypotension, or worsening oxygenation.

A client is brought to the emergency department with stroke symptoms that began 7 hours ago. A CT scan confirms the presence of an ischemic stroke. The client's current blood pressure is 202/108 mm Hg. Which nursing action is most appropriate?

• Anticipate IV labetalol to keep blood pressure <140/90 mm Hg
• Document the current findings in the client's chart
• Prepare to administer thrombolytic therapy
• Request a prescription for IV antiseizure medication

Explanation: Answer reason: With symptom onset at 7 hours, IV thrombolysis is not indicated, so immediate nursing priority is ongoing neurologic and hemodynamic assessment with accurate documentation and rapid communication of changes. Aggressively lowering blood pressure to <140/90 can reduce cerebral blood flow and worsen ischemia; BP is typically treated only if markedly elevated (e.g., >220/120) when not receiving reperfusion therapy. Antiseizure therapy is not given prophylactically unless seizures occur or are strongly suspected.

The nurse is caring for a client who is 1 day postoperative extensive abdominal surgery for ovarian cancer. The client is receiving intravenous (IV) Ringer's lactate at 100 mL/hr and continual epidural morphine for pain control. The Foley catheter urine output has decreased to <20 mL/hr over the past 2 hours. The postoperative hematocrit is 36%, and the hemoglobin is 12 g/dL. Which intervention should the nurse carry out first?

• Assess vital signs
• Increase the IV rate to 125 mL/hr
• Notify the health care provider (HCP)
• Perform a bladder scan

Explanation: Answer reason: Checking blood pressure, heart rate, temperature, and oxygenation determines whether this is an urgent perfusion problem requiring immediate escalation. Normal hemoglobin/hematocrit does not rule out early volume depletion or evolving blood loss, and urine output is a key end-organ perfusion indicator. Increasing IV fluids or calling the provider may be appropriate next steps, but assessment data are required first to guide safe, targeted intervention and urgency. A bladder scan can evaluate retention/obstruction, but unstable vital signs would take priority over troubleshooting catheter-related causes.

The nurse is performing an assessment of a pregnant client who is at 28 weeks of gestation. The nurse measures the fundal height in centimeters and notes that the fundal height is 30 cm. How should the nurse interpret this finding?

• The client is measuring large for gestational age.
• The client is measuring small for gestational age.
• The client is measuring normal for gestational age.
• More evidence is needed to determine size for gestational age.

Explanation: Answer reason: Fundal height in centimeters typically approximates gestational age in weeks from about 20 to 36 weeks. A commonly accepted normal variation is within about 2 cm of the gestational age due to factors like maternal habitus, fetal position, and measurement technique. At 28 weeks, a fundal height of 30 cm is within this expected range. Measurements that are more than a small margin above or below would prompt evaluation for conditions such as polyhydramnios, macrosomia, oligohydramnios, or fetal growth restriction.

The day care nurse is observing a 2-year-old child and suspects that the child may have strabismus. Which observation made by the nurse indicates the presence of this condition?

• The child has difficulty hearing.
• The child consistently tilts the head to see.
• The child does not respond when spoken to.
• The child consistently turns the head to hear.

Explanation: Answer reason: Strabismus is ocular misalignment that can cause diplopia or blurred vision and children often adopt compensatory head postures to optimize binocular vision and reduce symptoms. A persistent head tilt is a classic observational clue of an eye alignment problem rather than a hearing deficit. The hearing-focused findings (difficulty hearing, not responding when spoken to, turning head to hear) point to auditory impairment and do not specifically indicate ocular misalignment. Therefore the head tilt to see is the observation most consistent with strabismus and warrants referral for vision screening/ophthalmologic evaluation.

The nurse reviews an arterial blood gas report for a client with chronic obstructive pulmonary disease (COPD). The results are as follows: pH 7.35; Pco2 62 (8.25 kPa); Po2 70 (9.31 kPa); HCO3 34 mEq/L (34 mmol/L). The nurse should first?

• Apply a 100% nonrebreather mask.
• Assess the vital signs.
• Reposition the client.
• Prepare for intubation.

Explanation: Answer reason: ABGs show chronic compensated respiratory acidosis: elevated PaCO2 with elevated HCO3 and a near-normal pH, which is typical for stable COPD rather than an acute decompensation. The priority is to correlate these values with the client’s current clinical status (respiratory rate/effort, SpO2, mental status, hemodynamics) to determine urgency and appropriate escalation. High-flow 100% oxygen is not the first action in COPD because it can worsen CO2 retention and should be titrated based on assessment and oxygenation targets. Intubation is reserved for signs of impending respiratory failure (e.g., worsening acidosis, severe distress, declining consciousness), which cannot be concluded from these compensated values alone.

The nurse cares for a patient in Buck's traction. When assessing the patient what finding would indicate a complication?

• Leg discomfort.
• Brisk capillary refill.
• Weak pedal pulse.
• Drainage a pin sites.

Explanation: Answer reason: Traction and limb immobilization can compromise distal neurovascular status, so assessment focuses on perfusion, sensation, and movement. A diminished pedal pulse suggests impaired arterial flow from swelling, excessive traction, or tight bandaging and is an urgent complication requiring prompt intervention. In contrast, brisk capillary refill indicates adequate peripheral perfusion and is reassuring. Discomfort can occur with traction and is not as specific for vascular compromise, while pin-site drainage is associated with skeletal traction rather than Buck’s skin traction.

A clinic nurse is assessing the status of jaundice in a child with hepatitis. Which of the following anatomical areas will provide the best data regarding the presence of jaundice?

• The skin in the abdominal area
• The nail beds
• The membranes in the ear canal
• The skin in the sacral area

Explanation: Answer reason: The tympanic membranes/ear canal mucosa provide a relatively uniform, non–sun-exposed surface where yellow discoloration can be detected early and more reliably. Areas like the abdomen or sacrum can be affected by skin tone, lighting, and pressure-related color changes, reducing assessment accuracy. Nail beds can show color changes but are less sensitive and can be confounded by peripheral perfusion and temperature.

A nurse is performing an assessment of a client's peripheral vascular system. In which of the following locations should the nurse palpate the posterior tibial pulse?

• Below the medial malleolus
• In the popliteal fossa
• In the antecubital space
• On the dorsum of the foot

Explanation: Answer reason: The posterior tibial artery runs posterior to the medial malleolus, making this the correct landmark for palpation. The popliteal fossa corresponds to the popliteal pulse, the antecubital space to the brachial pulse, and the dorsum of the foot to the dorsalis pedis pulse. Choosing the correct site improves detection of impaired distal perfusion in peripheral vascular disease.

A nurse is caring for a client who has acute respiratory distress syndrome (ARDS) exacerbation. The health care provider (HCP) initiates noninvasive positive airway pressure ventilation (NIPPV) with a bilevel positive airway pressure (BiPAP) device. The nurse reviews the client's medical history. Which of the following parameters is most important for the nurse to monitor frequently in this client?

• Blood glucose level
• Capillary refill time
• Body temperature
• Mental status

Explanation: Answer reason: Frequent mental-status checks help detect hypoxemia, hypercapnia, fatigue, and impending need for escalation to invasive ventilation before overt collapse occurs. In ARDS exacerbation, clinical deterioration can occur quickly despite noninvasive support, so bedside neurologic trends complement pulse oximetry and vital signs. By contrast, parameters like blood glucose or capillary refill are not the most direct or earliest markers of inadequate ventilation/oxygenation in this context.

A 36-year-old primigravid client with a history of diabetes is admitted with preeclampsia. Which of the following actions should the nurse take FIRST?

• Administer low-dose aspirin as ordered.
• Ask the physician for an order for calcium supplements.
• Monitor the client's blood pressure.
• Prepare the client for delivery.

Explanation: Answer reason: In preeclampsia, the immediate nursing priority is early detection of worsening hypertension and end-organ compromise to prevent progression to stroke, eclampsia, placental abruption, and fetal compromise. Baseline and frequent blood pressure checks directly guide urgency of interventions (e.g., antihypertensives, magnesium sulfate, escalation of monitoring) and determine whether the situation is becoming an obstetric emergency. Low-dose aspirin and calcium are preventive measures used earlier in pregnancy for risk reduction and do not address acute stabilization on admission. Preparing for delivery may ultimately be required, but it is not the first step before assessing severity and maternal-fetal status.

The nurse is planning care for a client being admitted with newly diagnosed quadriplegia (tetraplegia). Which intervention will the nurse prioritize?

• Assess vital capacity and tidal volume once per shift and PRN
• Perform passive range of motion exercises on affected joints every 4 hours
• Provide time during each shift for the client to express feelings
• Turn the client every 2 hours throughout the day and night

Explanation: Answer reason: Serial measurement of vital capacity and tidal volume provides an objective early warning of declining ventilatory reserve and the need for escalation (e.g., assisted cough, noninvasive support, or intubation). Turning and ROM are important for preventing pressure injury and contractures, but they do not address the most immediate life-threatening risk. Allowing expression of feelings supports coping, yet it is not prioritized over physiologic stability in an acute admission.

The nurse admits an 81-year-old client with gastroenteritis. Admission vital signs are temperature 101 F (38.3 C), blood pressure 90/42 mm Hg, pulse 118/min, and respirations 32/min. Pulse oximetry shows 88%. The nurse suspects which of the following factors may be affecting accuracy of the pulse oximetry reading?

• Dehydration
• Elevated temperature
• Hypotension
• Tachypnea

Explanation: Answer reason: With low blood pressure (and likely vasoconstriction/poor perfusion in an ill older adult), the waveform can be weak, causing falsely low, erratic, or unreadable SpO2 values. In this client, 90/42 mm Hg strongly suggests compromised perfusion, making the pulse-ox reading less reliable. Fever and tachypnea do not typically interfere with the optical measurement itself, whereas low perfusion states are a classic cause of inaccuracy.

A client with type 2 diabetes, coronary artery disease, and peripheral arterial disease developed hospital-acquired pneumonia (HAP) and has been receiving Intravenous (IV) antibiotics for 4 days. Which parameter monitored by the nurse best indicates the effectiveness of treatment?

• Color of sputum
• Lung sounds
• Saturation level
• White blood cell count (WBC)

Explanation: Answer reason: A trending decrease toward normal in the WBC over several days of appropriate IV antibiotics indicates improving infection control and correlates with clinical recovery. Sputum color and lung sounds are less reliable because secretions can remain discolored and crackles may persist even as infection resolves. Oxygen saturation is important for current respiratory status but can be influenced by comorbid cardiopulmonary factors and supplemental oxygen, making it a less specific marker of antimicrobial response.

The purpose of a health assessment is to?

• Obtain subjective and objective data
• Outline appropriate care
• Determine whether interventions are effective
• Intervene to correct difficulties

Explanation: Answer reason: This includes subjective data (symptoms, history, concerns) and objective data (vital signs, physical exam findings, observable measures) to identify actual or potential problems. Planning appropriate care and intervening occur after assessment, once data have been analyzed into nursing diagnoses and priorities. Evaluating whether interventions are effective is part of the evaluation phase, not the primary purpose of the initial health assessment.

The RN is admitting a client with benign prostatic hyperplasia (BPH) to an acute care unit. The client describes an oral intake of about 1400 mL/day. What is the RN's priority concern?

• Ask the client about his or her bowel movements.
• Have the client complete a diet diary for the past 2 days.
• Instruct the client to increase oral intake to 2 to 3 L/day.
• Ask the client to describe his urine output.

Explanation: Answer reason: In BPH, the immediate safety risk is urinary retention and its complications (bladder overdistention, postrenal acute kidney injury, and infection), so the first priority is assessing voiding effectiveness. A reported fluid intake amount alone does not establish whether the client is obstructed; output pattern (frequency, hesitancy, weak stream, incomplete emptying, nocturia, or inability to void) directly reflects the severity of obstruction. Assessment should precede teaching or interventions because increasing fluids could worsen discomfort and retention if outflow is impaired. Bowel pattern and short-term diet diary are secondary compared with evaluating the urinary system in a client admitted for BPH.

An experienced LPN/LVN reports to the RN that a client's blood pressure and heart rate have decreased, and when his face was assessed, one side twitches. What action should the RN take at this time?

• Reassess the client's blood pressure and heart rate.
• Review the client's morning calcium level.
• Request a neurologic consult today.
• Check the client's pupillary reaction to light.

Explanation: Answer reason: The immediate priority is to validate and trend abnormal vital signs because bradycardia and hypotension can signal acute physiologic deterioration requiring rapid intervention. An RN must first perform a focused reassessment to confirm accuracy (cuff size/technique, apical pulse, rhythm) and determine current stability before escalating care. The unilateral facial twitching can represent a new neurologic finding (e.g., focal seizure activity) but does not replace the need to verify circulation status first. Reviewing calcium is relevant only if hypocalcemia is suspected (e.g., tetany) and is not the fastest safety action in the presence of potentially unstable hemodynamics. A neurologic consult is not the initial step until immediate assessment data are obtained and urgent responses are initiated if indicated.

A patient is receiving positive pressure mechanical ventilation and has a chest tube. When assessing the water seal chamber what do you expect to find?

• The water in the chamber will increase during inspiration and decrease during expiration.
• There will be continuous bubbling noted in the chamber.
• The water in the chamber will decrease during inspiration and increase during expiration.
• The water in the chamber will not move.

Explanation: Answer reason: With positive-pressure ventilation, the ventilator pushes air into the lungs, raising intrathoracic (pleural) pressure during inspiration. This reverses the usual “tidaling” pattern seen with spontaneous breathing, so the water level rises on inspiration and falls on expiration. Continuous bubbling would suggest an air leak rather than normal water-seal function. Observing expected tidaling helps confirm patency of the chest tube system and guides prompt detection of complications.

The nurse is performing nasotracheal suctioning of a client. The nurse determines that the client is adequately tolerating the procedure if which observation is made?

• The skin color becomes cyanotic.
• Secretions are becoming bloody.
• Coughing occurs with suctioning.
• The heart rate decreases from 78 to 54 beats per minute.

Explanation: Answer reason: A protective cough/gag response during nasotracheal suctioning indicates the airway reflexes are intact and the catheter is stimulating the tracheobronchial tree appropriately. This suggests the client is maintaining airway patency and neurologic responsiveness during the procedure. In contrast, cyanosis signals hypoxemia, and a marked heart-rate drop reflects vagal stimulation–induced bradycardia, both indicating poor tolerance requiring stopping suctioning and re-oxygenation. Bloody secretions suggest mucosal trauma from excessive suction pressure or technique and also indicate intolerance/complication.

When examining a patient with abdominal pain the nurse in charge should assess?

• Any quadrant first
• The symptomatic quadrant first
• The symptomatic quadrant last
• The symptomatic quadrant either second or third

Explanation: Answer reason: Palpating the painful area first increases voluntary and involuntary muscle tension, which can make subsequent assessment inaccurate and more uncomfortable. Starting away from the site of pain allows comparison of normal versus abnormal findings and supports a more reliable exam. A common error is going directly to the painful area, which risks escalating discomfort and limiting cooperation.

Which vital sign in a pediatric client is most important to report to the primary health care provider?

• Newborn with a heart rate of 140 beats/min
• Three-year-old with a respiratory rate of 28 breaths/min
• Six-year-old with a heart rate of 130 beats/min
• Twelve-year-old with a respiratory rate of 16 breaths/min

Explanation: Answer reason: Pediatric vital signs must be interpreted by age-specific norms, and school-age children should not have persistent tachycardia at rest. A heart rate of 130/min in a 6-year-old is above the expected range and can indicate early compromise such as fever, dehydration, pain/anxiety, hypoxia, or shock, warranting provider notification and further evaluation. In contrast, a newborn heart rate around 140/min is within normal limits for neonates, and a 3-year-old respiratory rate of 28/min is typically acceptable for toddlers/preschoolers. A 12-year-old respiratory rate of 16/min is normal for an older child/adolescent.

A patient recovers from orthopedic surgery with a cast on their leg. When the nurse assesses the patient what is the highest priority?

• Bladder distension.
• Skin breakdown.
• Capillary refill.
• Extremity shortening

Explanation: Answer reason: Neurovascular compromise is the most urgent cast-related risk after orthopedic surgery because impaired circulation can rapidly progress to ischemia and compartment syndrome. Assessing distal perfusion with capillary refill provides a quick, sensitive screen for inadequate arterial flow to the affected extremity. Abnormal findings (delayed refill, coolness, pallor, increasing pain) require immediate escalation and potential cast splitting/bivalving to prevent permanent damage. Skin breakdown is important but is typically less immediately limb-threatening than loss of perfusion. Bladder distension is a postoperative concern but does not supersede potential limb ischemia in this context.

A 25-year-old is found unconscious with fever and a noticeable rash. Which of the following tests will most likely be a priority order?

• Blood sugar check
• CT scan
• Blood cultures
• Arterial blood gases

Explanation: Answer reason: Unconsciousness requires immediate assessment for rapidly reversible, life-threatening causes, and hypoglycemia is a common, quickly correctable etiology. A bedside glucose test can be obtained within seconds and directly guides urgent treatment with dextrose if low. Fever and rash raise concern for serious infection (e.g., meningococcemia), but cultures take time and should not delay immediate stabilization and rapid causes screening. CT and ABGs may be indicated after initial stabilization, but they are not the fastest priority test that can immediately change management in an unconscious patient.

A client with infective endocarditis is at risk for heart failure. The nurse monitors the client for which signs and symptoms of heart failure?

• Lung crackles, peripheral edema, and weight gain
• Confusion, decreasing level of consciousness, and aphasia
• Respiratory distress, chest pain, and the use of accessory muscles
• Flank pain with radiation to the groin, accompanied by hematuria

Explanation: Answer reason: Crackles indicate fluid in the alveoli from left-sided failure, while peripheral edema and rapid weight gain reflect right-sided or overall volume overload. Infective endocarditis can damage valves and reduce forward flow, precipitating these classic congestion findings. The neurologic findings listed are more consistent with embolic stroke, and flank pain with hematuria suggests renal/urinary pathology rather than heart failure. Chest pain with severe respiratory distress can occur in pulmonary embolism or acute coronary syndromes and is not the typical triad used to monitor for developing congestive failure.

The nurse is caring for a client on a mechanical ventilator. The settings on the ventilator have just been changed, and the standing prescription is to draw arterial blood gases 30 minutes after a ventilator change. In anticipation of this blood draw, what intervention should the nurse implement?

• Avoid suctioning the client
• Pre-oxygenate the client
• Raise the head of the bed
• Reduce the amount of sedation medication

Explanation: Answer reason: Suctioning can transiently alter oxygenation and ventilation (hypoxemia from derecruitment, changes in PaCO2 from stimulation/coughing), which can skew results and lead to inappropriate ventilator adjustments. Therefore, unless clinically necessary (e.g., visible secretions/airway obstruction), suctioning should be avoided immediately before obtaining ABGs. Pre-oxygenation is indicated before suctioning to prevent hypoxemia, not as a routine step before an ABG draw.

A client who has experienced an inhalation injury reports episodes of respiratory wheezing. The nurse assesses the client and does not hear wheezing. Which of the following is the appropriate nursing intervention?

• Increase the IV infusion rate.
• Elevate the head of the bed at least 60°.
• Reassess the client's airway immediately.
• Document the findings as indicating resolution of airway obstruction.

Explanation: Answer reason: Inhalation injury can cause evolving airway edema and bronchospasm, and breath sounds can change rapidly. Absence of wheezing is not reassuring; markedly diminished or absent wheezing can indicate severe airflow limitation (“silent chest”) and impending respiratory failure. The safest action is to promptly reassess airway patency and ventilation (work of breathing, stridor, SpO2, ability to speak) to detect deterioration early. Positioning may help ventilation, but it does not replace urgent reassessment when the client reports intermittent symptoms that may not be present at one moment in time.

A nurse is caring for a client who has chronic obstructive pulmonary disease who has difficulty breathing. Which of the following nursing actions should be performed prior to administering oxygen?

• Monitor the client's arterial blood gas results.
• Observe the client's respiratory pattern.
• Instruct the client on application of an oxygen cannula.
• Determine if the client has chronic hypercarbia.

Explanation: Answer reason: Oxygen is a medication that can worsen CO2 retention in some clients with COPD who chronically retain CO2, so assessing baseline ventilatory drive and CO2 status is a key safety step before initiating therapy. Knowing whether chronic hypercarbia is present guides the nurse to start low-flow oxygen and target appropriate SpO2 ranges while closely monitoring for hypoventilation and rising PaCO2. This pre-administration assessment helps prevent oxygen-induced hypercapnia and respiratory acidosis. ABGs may be ordered and are useful, but the priority nursing action is to first determine whether the client is a chronic CO2 retainer because it directly changes how oxygen should be administered and monitored.

The spouse of a client calls the nurse at the clinic and reports that the client is not feeling well and is concerned that something is seriously wrong. How should the nurse respond initially?

• Ask the spouse to further describe the client's symptoms (88%)
• Indicate that privacy rules prevent discussion of concerns with the spouse (1%)
• Offer a same-day appointment to the client (4%)
• Tell the spouse to have the client call the nurse (6%)

Explanation: Answer reason: Gathering specific symptom details (onset, severity, red flags like chest pain, dyspnea, neuro deficits, fever, bleeding) allows the nurse to make a safe, appropriate disposition. Immediately offering an appointment can delay needed emergency evaluation if warning signs are present, and asking the client to call first may also waste time in a potentially serious situation. Privacy considerations matter, but the immediate priority is to collect enough information to guide safe next steps without disclosing protected health information beyond what is necessary for triage.

The fetus of a client in the transitional phase of labor has a baseline heart rate of 175 bpm, with moderate variability. What nursing intervention is appropriate at this time?

• The nurse should measure maternal temperature.
• The nurse should assess for prolapsed umbilical cord.
• These accelerations do not require an intervention.
• The nurse should switch to internal fetal heart monitor.

Explanation: Answer reason: Fetal tachycardia (>160 bpm) with preserved (moderate) variability suggests the fetus is compensating and prompts assessment for reversible causes rather than immediate invasive monitoring. Maternal fever/infection (e.g., chorioamnionitis) and dehydration are common, high-yield causes of fetal tachycardia during labor and are quickly screened by checking the mother’s temperature. A prolapsed cord typically produces abrupt variable decelerations and/or fetal bradycardia, not an isolated elevated baseline. Internal monitoring may improve tracing quality but does not address the likely etiology and is not the first action when the pattern is otherwise reassuring.

A client was admitted to the hospital 24 hours ago after sustaining blunt chest trauma. Which is the earliest clinical manifestation of acute respiratory distress syndrome (ARDS) the nurse should monitor for?

• Cyanosis with accompanying pallor
• Diffuse crackles and rhonchi on chest auscultation
• Increase in respiratory rate from 18 to 30 breaths per minute
• Haziness or “white-out” appearance of lungs on chest radiograph

Explanation: Answer reason: An increased respiratory rate is typically an earlier and more sensitive bedside change than late signs like cyanosis, which occur after significant hypoxemia. Adventitious breath sounds such as diffuse crackles may appear as fluid and atelectasis progress, but they are not usually the earliest manifestation. Radiographic “white-out” changes reflect more advanced diffuse alveolar involvement and generally lag behind early clinical deterioration.

A nurse is collecting data from a client who has ataxia. Which of the following is appropriate to evaluate the client’s ability to safely ambulate?

• Observe for the presence of Kernig’s sign.
• Perform a Romberg’s test.
• Check the function of cranial nerve V.
• Inspect for the presence of clubbing.

Explanation: Answer reason: Safe ambulation requires adequate balance and postural stability, which depend on proprioception, vestibular input, and cerebellar integration. This bedside test specifically assesses balance by having the client stand with feet together and then with eyes closed to detect increased sway or loss of balance, helping quantify fall risk in ataxia. A positive finding supports the need for gait assistance and safety precautions during mobility. Kernig’s sign is aimed at meningeal irritation, cranial nerve V testing focuses on facial sensation/mastication, and clubbing relates to chronic hypoxemia—none directly evaluate gait safety.

An elderly client with end-stage renal disease who has chosen not to go on dialysis is admitted to a long-term care facility for rehabilitation following hospitalization. The next day the client becomes agitated and says to the nurse, "I've got to get back home to my things. I have so much to do." Which is the most likely interpretation of this client's behavior?

• The client has been admitted to the facility without the client's consent
• The client is becoming delirious and should be assessed for infection
• The client is concerned that someone might steal possessions
• The client will die soon and needs to take care of business

Explanation: Answer reason: Delirium commonly has a reversible medical trigger (e.g., infection), and clients with end-stage renal disease are at higher risk due to metabolic derangements and overall physiologic vulnerability. A nursing priority is to interpret this sudden change as a potential acute medical problem and promptly assess for underlying causes rather than assuming a purely psychosocial motive. The other options describe possible concerns, but they do not best explain a rapid onset change in mentation/behavior in this high-risk setting.

The nurse is collecting data on a client who is at 38 weeks' gestation and notes that the fetal heart rate (FHR) is 174 beats/minute. Based on this finding, what is the most appropriate nursing action?

• Document the finding.
• Check the mother's heart rate.
• Tell the client that the FHR is normal.
• Notify the primary health care provider.

Explanation: Answer reason: A baseline fetal heart rate is typically 110–160/min, so a reading of 174/min suggests fetal tachycardia and requires prompt assessment rather than reassurance. Before escalating care, the nurse should validate the data by ensuring the detected rate is truly fetal and not the maternal pulse being auscultated (a common source of error with intermittent monitoring). Confirming the maternal heart rate helps distinguish maternal from fetal signals and guides next steps (e.g., continued monitoring and provider notification if tachycardia is confirmed). Simply documenting or stating it is normal delays evaluation, and notifying the provider is appropriate after initial nursing verification and assessment.

The nurse is monitoring the nutritional status of a client who is receiving enteral nutrition. Which should the nurse monitor as the best clinical indicator of the client’s nutritional status?

• Daily weight
• Calorie count
• Skinfold measurement
• Serum prealbumin level

Explanation: Answer reason: Weight can change rapidly from fluid shifts and edema, making it less specific for nutritional improvement or decline. Calorie counts reflect intake but do not confirm absorption/utilization and can miss the impact of stress, inflammation, or losses. Skinfold measurements are indirect and less practical for frequent monitoring in ill or hospitalized clients, with significant technique-related variability.

A 10-month old baby with a fractured right femur is admitted to the pediatric unit. Which action should the nurse take first?

• Ask the parents how the fracture occurred.
• Do a quick physical assessment.
• Ask the hospital social worker to come to the unit.
• Administer pain medication.

Explanation: Answer reason: Initial nursing priority is to assess for immediate threats and complications before intervening, using an ABCs/safety-first framework. With an infant femur fracture, the nurse must rapidly evaluate neurovascular status of the affected limb (color, temperature, pulses/cap refill, movement, sensation), overall perfusion, and signs of shock or additional injuries. This assessment establishes a baseline and identifies urgent problems (e.g., compromised circulation) that would change the plan and require prompt provider notification. Pain medication is important but should follow rapid assessment to ensure no evolving emergency is missed, and questions about mechanism/social work referral can be addressed after stabilization and initial evaluation.

The nurse in the intensive care unit (ICU) is giving unlicensed assistive personnel (UAP) directions for bathing a client who has a surgical incision infected with methicillin-resistant Staphylococcus aureus (MRSA). Which instructions would be most effective for reducing infection?

• Assist the client to the shower and provide directions to use antibacterial soap
• Delay the bath until the client has received antibiotic therapy for 24 hours
• Use a bath basin with warm water and a new wash cloth for each body area
• Use packaged pre-moistened cloths containing chlorhexidine to bathe the client

Explanation: Answer reason: Prepackaged CHG cloths also standardize technique and avoid contamination risks associated with reusable basins that can harbor pathogens and spread them between patients. Showering with “antibacterial soap” is less reliable and may not provide the sustained antimicrobial effect of CHG. Waiting for antibiotics delays hygiene and does not address contact spread from skin colonization, which is a key infection-control target.

A nurse manager is planning an in-service for a group of nurses about caring for clients following stem cell transplants. Which of the following instructions should the nurse manager include in the teaching?

• Assign two clients who have had a stem cell transplant to the same room.
• Obtain a rectal temperature on clients every 4 hr.
• Wear an N95 respirator mask while caring for these clients.
• Place clients in positive-pressure airflow rooms.

Explanation: Answer reason: Protective (reverse) isolation is the key principle after stem cell transplant because profound neutropenia makes the client highly susceptible to airborne and environmental pathogens. Positive-pressure rooms reduce entry of unfiltered corridor air and help prevent exposure to organisms such as fungal spores. Rectal temperatures should be avoided due to risk of mucosal injury and bacteremia in immunocompromised clients. Routine N95 use is not required unless the client is on airborne precautions for a specific infection; the priority is environmental protection and strict infection-control measures.

The nurse is preparing a continuous intravenous (IV) infusion at the medication cart. As the nurse goes to insert the spike end of the IV tubing into the IV bag, the tubing drops and the spike end hits the top of the medication cart. The nurse should take which action?

• Obtain a new IV bag.
• Obtain new IV tubing.
• Wipe the spike end of the tubing with povidone iodine.
• Scrub the spike end of the tubing with an alcohol swab.

Explanation: Answer reason: Maintaining sterility of the IV administration set is a core infection-control principle because any contamination of the spike can directly introduce microorganisms into the IV fluid pathway and bloodstream. Once the spike touches a nonsterile surface, it is considered contaminated and cannot be reliably re-sterilized at the bedside with wipes or swabs. Replacing the tubing removes the contaminated component and restores a sterile infusion setup. Replacing the IV bag is unnecessary because the bag has not been breached, and antiseptics on the spike risk incomplete decontamination and introducing chemical residue into the system.

A burn client's care plan reveals an expected outcome of no localized or systemic infection. Which assessment by the nurse supports this outcome?

• Wound culture results that show minimal bacteria
• Cloudy, foul-smelling urine output
• White blood cell count of 14,000
• Temperature of 101°F

Explanation: Answer reason: A culture showing minimal bacteria indicates no significant local colonization progressing toward invasive infection. The other findings suggest infection: cloudy, foul-smelling urine points to a UTI, a WBC of 14,000 indicates leukocytosis, and a temperature of 101°F indicates fever and possible systemic involvement. Therefore, the culture result is the assessment most consistent with the expected outcome.

The nurse plans to collect a urine specimen from a client with an indwelling urinary catheter. Which action does the nurse take?

• Clamp the drainage tubing below the aspiration port.
• Disconnect the catheter from drainage tubing to obtain the specimen.
• Insert a 21G needle into the shaft of the catheter tubing.
• Irrigate the catheter prior to collecting the specimen.

Explanation: Answer reason: Urine specimens from an indwelling catheter should be collected from the designated sampling (aspiration) port using aseptic technique to minimize CAUTI risk and to avoid contaminating the closed drainage system. Clamping the tubing distal to the sampling port allows fresh urine to pool in the tubing/bladder segment so an adequate, current sample can be withdrawn. Disconnecting the catheter from the drainage tubing breaks the closed system and increases infection risk. Inserting a needle into the tubing can create leaks and introduces contamination, and irrigating before collection dilutes the sample and can alter culture/urinalysis results unless specifically prescribed.

A client who has been diagnosed with possible avian influenza is admitted to the medical unit. Which prescribed action will the nurse take first?

• Place the client in an airborne isolation room.
• Initiate infusion of 500 mL of normal saline bolus.
• Ask the client about any recent travel to Asia.
• Obtain sputum specimen and nasal cultures.

Explanation: Answer reason: The core priority with suspected avian influenza is immediate transmission prevention because it is a potentially severe respiratory infection with risk of spread in a healthcare setting. Implementing appropriate isolation is a time-critical nursing action that protects other patients and staff before additional assessments or procedures increase exposure. Diagnostic cultures can be obtained after precautions are in place to reduce aerosol/droplet generation risk during specimen collection. A fluid bolus is only first if there is evidence of hemodynamic instability, which is not provided in the stem.

The home health nurse teaches a client how to procure a clean-catch urine specimen. Which statement indicates that the client understands the nurse’s instructions?

• “I will keep the collection bottle in an ice-filled cooler.”
• “I will strain my urine and empty the nephroliths into the specimen bag.”
• “I need to don sterile gloves, clean myself with iodine solution, and then collect a sterile specimen.”
• “I will urinate a small amount into the toilet and collect the remaining sample in a clean collection cup.”

Explanation: Answer reason: A clean-catch (midstream) urine specimen is collected by voiding the initial urine stream to flush urethral contaminants, then collecting the midstream portion in a clean container to reduce false contamination. This statement correctly describes discarding the first small amount and then collecting the remaining midstream sample. Keeping a bottle on ice is not part of the collection technique being taught and relates more to specimen preservation after collection. Using sterile gloves/iodine and calling it a sterile specimen describes a sterile collection (or an overly sterile technique) rather than the standard clean-catch method taught to most clients at home.

A home health nurse is planning care for a client who is receiving chemotherapy and has neutropenia. Which of the following foods should the nurse include in the client's plan of care?

• Soft-boiled eggs
• Raw carrots
• Spinach salad
• Baked chicken

Explanation: Answer reason: A fully cooked poultry dish fits this principle because heat reduces bacterial load and makes the food safer. Soft-boiled eggs are often undercooked and can harbor Salmonella, and raw vegetables/leafy salads can carry pathogens that are difficult to eliminate even with washing. Therefore, the safest choice among the options is the fully cooked entrée.

A mother has heard that several children have been diagnosed with mononucleosis. She asks the nurse what precautions should be taken to prevent this from occurring in her child. The nurse should instruct the mother to?

• Take no particular precautionary measures.
• Sterilize the child's eating utensils before they are reused.
• Wash the child's linens separately in hot, soapy water.
• Wear masks when providing direct personal care.

Explanation: Answer reason: Infectious mononucleosis (typically EBV) is primarily transmitted through saliva with close personal contact, and it is not effectively prevented by routine household sterilization or special laundry practices. Standard hygiene (handwashing, avoiding sharing drinks/utensils when someone is ill) is reasonable, but there are no specific isolation-type precautions recommended for healthy children in the community to prevent acquisition. Sterilizing utensils and separating linens suggest fomite or contact-spread control measures that are not central to EBV transmission. Mask use is aimed at droplet/airborne pathogens and is not indicated for typical mono exposure in the home/community setting.

The color of bag in which the infectious solids wastes are disposed?

• Red
• Black
• Blue
• Yellow

Explanation: Answer reason: Infectious solid waste (soiled items contaminated with blood/body fluids) is placed in designated biohazard bags intended for contaminated solids, which are commonly red. This directs staff to apply appropriate precautions and ensures correct downstream treatment (e.g., disinfection/incineration) for infectious material. Black is generally reserved for non-infectious/general waste, while blue and yellow are typically used for other specific waste streams depending on local policy, making them less appropriate for infectious solids here.

A client receiving parenteral nutrition (PN) suddenly develops a fever. The nurse notifies the health care provider (HCP), and the HCP initially prescribes that the solution and tubing be changed. What should the nurse do with the discontinued materials?

• Discard them in the unit trash.
• Return them to the hospital pharmacy.
• Save them for return to the manufacturer.
• Prepare to send them to the laboratory for culture.

Explanation: Answer reason: Fever in a client on PN raises concern for catheter-related bloodstream infection or contaminated PN solution, so potential sources should be cultured to guide targeted therapy. Sending the discontinued solution and tubing for culture preserves evidence of contamination and supports appropriate antimicrobial selection and infection-control actions. Discarding them removes the opportunity to identify the organism and source. Returning to pharmacy/manufacturer does not address the immediate clinical need to evaluate infection risk and manage the patient safely.

The nurse is caring for a client with a diagnosis of breast cancer who is immunosuppressed. The nurse would consider implementing neutropenic precautions if the client's white blood cell count was which value?

• 2000 mm3 (2.0 × 10^9/L)
• 5800 mm3 (5.8 × 10^9/L)
• 8400 mm3 (8.4 × 10^9/L)
• 11,500 mm3 (11.5 × 10^9/L)

Explanation: Answer reason: 2000 mm3 (2.0 × 10^9/L) Neutropenic precautions are implemented when the patient’s infection risk is high due to markedly reduced leukocyte/particularly neutrophil availability, most commonly reflected by very low WBC/ANC in oncology patients. A WBC of 2000/mm3 indicates significant leukopenia and strongly suggests a potentially dangerously low absolute neutrophil count, warranting protective measures (strict hand hygiene, avoiding sick contacts, limiting raw foods/flowers per policy, monitoring for fever). Values like 5800/mm3 and 8400/mm3 are within typical adult reference ranges and do not indicate neutropenia by themselves. Although 11,500/mm3 may indicate inflammation or stress leukocytosis, it does not signal immunosuppression requiring neutropenic precautions.

The nurse is assigned to care for an infant on the first postoperative day after a surgical repair of a cleft lip. Which nursing intervention is appropriate when caring for this child's surgical incision?

• Rinsing the incision with sterile water after feeding
• Cleaning the incision only when serous exudate forms
• Rubbing the incision gently with a sterile cotton-tipped swab
• Replacing the Logan bar carefully after cleaning the incision

Explanation: Answer reason: Gentle rinsing with sterile water after feeds helps keep the incision clean without applying friction or pressure that could disrupt the repair. Waiting to clean until drainage appears is reactive and allows residue to remain in place, increasing risk of crusting and infection. Direct rubbing with a swab can traumatize the delicate suture line and precipitate bleeding or dehiscence. Keeping the Logan bar in place is important, but the key appropriate routine incision-care action immediately after feeds is cleansing/rinsing to remove contaminants.

Anurag is put on a femoral venous catheter in a hospital. What should a nurse to while caring for Anurag-?

• Irrigate the catheter with sterile saline solution to retain patency
• Maintain sterility when working with the catheter
• Evaluate the pressure dressing frequently for bleeding
• Limit the mobility of the affected limb

Explanation: Answer reason: Using sterile technique for hub access, dressing changes, and line manipulation reduces contamination and subsequent sepsis risk. Routine irrigation/flushes are not universally indicated unless prescribed and can introduce organisms or cause complications if done improperly. While monitoring for bleeding and limiting hip flexion/movement can be helpful with femoral sites, infection prevention remains the highest-priority, always-applicable intervention.

A nurse is providing care for a client who had kidney transplant surgery. The nurse should advise the client that taking immunosuppressive medications can result in which of the following?

• Increased urinary output
• Increased susceptibility to infection
• Decreased vision
• Increased risk of autoimmune disorders

Explanation: Answer reason: This makes opportunistic and common infections more likely and often more severe, so teaching emphasizes early symptom reporting and infection-prevention behaviors. Increased urinary output reflects graft function and fluid status rather than a direct expected consequence of immune suppression. Autoimmune disorders are not an expected result because these medications dampen, rather than stimulate, immune responses.

A student nurse performs the morning assessment and obtains a urine specimen from a client with methicillin-resistant Staphylococcus aureus (MRSA) who is in contact precautions. The registered nurse intervenes when the student performs which action?

• Cleans the stethoscope with 2% chlorhexidine solution before removing it from the room
• Removes the urine specimen cup from the room in a sealed, leak-proof bag
• Scrubs the Foley catheter collection port with alcohol for 15 seconds before withdrawing a urine specimen
• Uses an alcohol-based hand antiseptic after removing gloves

Explanation: Answer reason: Using a 2% chlorhexidine solution is not the standard method for disinfecting a stethoscope and can be inconsistent with recommended environmental disinfection practices, so the RN should stop and correct this. The other actions reflect correct infection-control technique: transporting the specimen in a sealed leak-proof bag, disinfecting the sampling port before access, and performing hand hygiene after glove removal. The priority is preventing cross-contamination with correct, approved disinfection procedures.

The nurse admits several clients during the day shift. Which room assignment is most appropriate for the nurse to make?

• Assign the client who is returning from an appendectomy to a room with a client who had an incision and drainage of a leg wound earlier today.
• Assign the client who is returning from a total knee replacement to a room with a client diagnosed with pancreatitis.
• Assign the client diagnosed with streptococcal pneumonia to a room with a client diagnosed with staphylococcal pneumonia.
• Assign the client diagnosed with gastritis to a room with a client who is neutropenic.

Explanation: Answer reason: Room assignments should minimize cross-transmission risk by avoiding pairing clients with contagious infections or highly vulnerable immune status with potentially infectious roommates. A postoperative orthopedic client and a pancreatitis client are not inherently infectious, so cohorting them does not add specific transmission-based precaution conflicts. In contrast, pairing two clients with different bacterial pneumonias risks exposure to different organisms and may require different isolation measures. Also, a neutropenic client should not room with someone with a gastrointestinal illness due to heightened risk of acquiring infection.

The nurse teaches a pregnant client diagnosed with human immunodeficiency virus (HIV) about measures to prevent opportunistic infections. Which client statement indicates that the teaching has been effective?

• "I need to eat pasteurized food."
• "My husband is taking care of cleaning the fish tank."
• "I know I must have a cesarean section to avoid infecting my baby."
• "I am going to a big family party this weekend, and I am really looking forward to it."

Explanation: Answer reason: " Immunocompromised clients are at increased risk for opportunistic infections from environmental exposures, including pathogens found in aquarium water and animal waste. Avoiding or delegating tasks like cleaning fish tanks reduces exposure to waterborne organisms that can cause serious infection. In contrast, simply attending a large gathering increases exposure to contagious illnesses and is not a preventive measure. Delivery method decisions relate primarily to vertical transmission risk management and depend on viral load and treatment, not on preventing opportunistic infections.

The nurse is caring for a patient with AIDS. The nurse should implement neutropenic precautions when the patient's white blood cell count is?

• 11,500 cells/mm²
• 15,000 cells/mm²
• 4,900 cells/mm²
• 3,000 cells/mm²

Explanation: Answer reason: A total WBC of 3,000 cells/mm² strongly suggests clinically meaningful immunosuppression and likely neutropenia, warranting protective measures to reduce exposure to pathogens. By contrast, 11,500 and 15,000 cells/mm² are elevated counts typically associated with inflammation/infection rather than neutropenia. A WBC of 4,900 cells/mm² is near the lower end of normal for many labs and is less consistent with severe immunosuppression requiring strict neutropenic precautions without additional ANC data.

The nurse observes a student nurse inserting an indwelling urinary catheter for a female client. After the student inserts the catheter, no urine appears and the student begins to remove the catheter. What should the nurse do at this time?

• Ask the student in a calm voice: "Did you do something wrong?"
• Walk up and whisper in the student's ear: "Stop. Leave the catheter in place. I'll get a new sterile catheter."
• In a speaking tone of voice, explain: "The tubing is probably in the vagina."
• State strongly: "Stop. Tell me why there's no urine in the tubing."

Explanation: Answer reason: Walk up and whisper in the student's ear: "Stop. Leave the catheter in place. I'll get a new sterile catheter." When a female urinary catheter is inadvertently placed in the vagina, urine will not return; removing it eliminates the key landmark and increases the risk of repeating the error. Leaving the catheter in place allows it to serve as a guide while a new sterile catheter is obtained and inserted correctly into the urethra, reducing contamination and trauma. Coaching quietly preserves the client’s dignity and supports the student without alarming the client. Publicly announcing the likely misplacement or interrogating the student delays correction and can breach therapeutic communication while not addressing infection-control needs.

The client with chronic renal failure returns to the nursing unit following a hemodialysis treatment. On assessment the nurse notes that the client's temperature is 100.2. Which of the following is the most appropriate nursing action?

• Encourage fluids
• Notify the physician
• Monitor the site of the shunt for infection
• Continue to monitor vital signs

Explanation: Answer reason: The priority nursing action is focused assessment of the dialysis access (shunt/AV fistula or graft) for local signs such as warmth, erythema, tenderness, swelling, drainage, and changes in bruit/thrill. Prompt identification supports rapid escalation (cultures/antibiotics) if findings suggest infection. Encouraging fluids is inappropriate in chronic renal failure due to fluid restrictions, and simply continuing routine vital signs is less targeted than assessing the most likely source.

The most effective way to break the chain of infection is?

• Hand hygiene
• Wearing gloves
• Placing clients in isolation
• Providing private rooms for clients.

Explanation: Answer reason: Consistent hand cleansing before and after patient contact reduces cross-contamination regardless of whether gloves are used or what room type the patient is in. Gloves can develop microtears and become contaminated during removal, so they do not replace proper hand cleansing. Isolation and private rooms are useful for specific pathogens and situations but are less universally effective than hand cleansing across all contacts.

The nurse in the long-term care facility provides care for clients during an outbreak of Legionnaire disease. The nurse recognizes that which client is most at risk to develop the disease?

• A 95-year-old client diagnosed with a fractured right hip.
• An 85-year-old client diagnosed with a right-sided cerebrovascular accident.
• A 75-year-old client diagnosed with Alzheimer disease.
• A 65-year-old client diagnosed with end-stage kidney disease.

Explanation: Answer reason: Legionnaires’ disease (Legionella pneumonia) disproportionately affects people with impaired immune defenses and chronic systemic illness, leading to higher susceptibility and more severe infection. End-stage kidney disease is associated with immune dysfunction and often frequent healthcare exposures, both of which increase risk during an institutional outbreak. Advanced age alone raises risk, but the hip fracture, CVA, and Alzheimer diagnoses do not inherently create the same level of immunocompromise as ESRD. Therefore, the client with ESRD is the most vulnerable in this set.

A client with acute leukemia develops a low white blood cell count. In addition to isolation, the nurse should?

• Ask the client to wear a mask when visitors are present
• Prep IV sites with mild soap and water and alcohol
• Provide foods in sealed, single-serving packages
• Request that foods be served with disposable utensils

Explanation: Answer reason: Sealed, single-serving packages reduce handling and the chance of contamination compared with shared containers or unsealed items, aligning with neutropenic dietary precautions when ordered by the facility/provider. Having the client wear a mask for visitors is not the key control measure; instead, visitors with illness should be restricted and staff/visitors should perform meticulous hand hygiene and use PPE as indicated. “Mild soap and water and alcohol” is not appropriate skin antisepsis for IV insertion compared with recommended antiseptics (e.g., chlorhexidine), and disposable utensils do not meaningfully reduce infection risk compared with ensuring proper food preparation and limiting exposure sources.

A home care nurse visits a child with a diagnosis of celiac disease. Which finding best indicates that a gluten-free diet is being maintained and has been effective?

• The child is free of diarrhea.
• The child is free of bloody stools.
• The child tolerates dietary wheat and rye.
• A balanced fluid and electrolyte status is noted on the laboratory results.

Explanation: Answer reason: Celiac disease causes immune-mediated villous atrophy leading to malabsorption, which commonly presents with chronic diarrhea and bulky/foul stools. Effective adherence to a gluten-free diet reduces intestinal inflammation and improves absorption, so normalization of stool pattern is an early, clinically meaningful indicator of response. Absence of blood in stool is not a typical hallmark of celiac disease and does not specifically reflect dietary control. Normal fluid/electrolyte labs can occur despite ongoing intestinal injury and are less direct than the primary symptom improvement.

The patient is on bleeding precaution and now having constipation which action will you implement?

• Avoid straining
• Give stool softener
• Increase fiber in the diet
• Encourage ambulation

Explanation: Answer reason: Constipation increases the risk of straining, which can precipitate hemorrhoidal or rectal bleeding and also trigger vagal responses in vulnerable patients. A stool softener (e.g., docusate) directly reduces stool hardness and straining risk without causing aggressive bowel stimulation. Increasing fiber and ambulation are helpful longer-term measures but are slower acting and may be limited by hydration status or mobility; the most immediately protective intervention is to soften stool.

A female patient complains of abdominal discomfort. Watery stool has been leaking from her rectum. This could be a sign of?

• Bowel incontinence
• Fecal impaction
• Diarrhea
• Constipation

Explanation: Answer reason: This pattern is classic for an impaction rather than true increased stool output. Diarrhea typically causes frequent loose stools with urgency, not small-volume leakage around an obstruction. Recognizing this prevents inappropriate use of antidiarrheals and prompts assessment for impaction and relief measures (e.g., rectal exam, disimpaction/enema as ordered, hydration, and bowel regimen).

The primary goal of nursing care for a client with stress incontinence is to?

• Help the client adjust to the frequent episodes of incontinence.
• Eliminate all episodes of incontinence.
• Prevent the development of urinary tract infections.
• Decrease the number of incontinence episodes.

Explanation: Answer reason: The core nursing goal for stress incontinence is improving continence through strengthening pelvic floor support and adopting bladder-training/behavioral strategies, which typically reduces leakage frequency rather than guaranteeing a cure. This outcome is realistic, measurable, and directly tied to first-line interventions like Kegel exercises, weight management, and timed voiding. Completely eliminating episodes is not always achievable, especially when anatomic or age-related sphincter weakness persists, making it an unrealistic primary goal. Preventing UTIs and helping the client adjust are important secondary aims, but they do not address the main problem of urine leakage frequency.

The movement of a client from a lower to a higher level of care and intensity of care is an example of?

• A decreasing level of acuity.
• Retrospective reimbursement.
• Movement along the continuum of care.
• Prospective reimbursement.

Explanation: Answer reason: Continuity of care refers to coordinating and transitioning a client between settings as care needs change in acuity and required resources. Moving from a lower level (e.g., med-surg, rehab) to a higher intensity setting (e.g., step-down, ICU) represents an escalation within that continuum to match the client’s current status. A decreasing level of acuity would imply improvement and typically movement to a less intensive setting, not a higher one. Reimbursement terms describe payment methodology and do not describe clinical transitions between levels of care.

Which drug belongs to the aminoglycoside antibiotic class?

• Gentamicin
• Erythromycin
• Amoxicillin
• Ceftriaxone

Explanation: Answer reason: g., gentamicin, amikacin, tobramycin) known for concentration-dependent killing and notable risks of nephrotoxicity and ototoxicity. Among the options, gentamicin is the only aminoglycoside. Erythromycin is a macrolide, amoxicillin is a penicillin (beta-lactam), and ceftriaxone is a third-generation cephalosporin (beta-lactam). Recognizing antibiotic classes helps anticipate spectrum and key adverse effects relevant to safe use and monitoring.

Which group of drugs is mainly used in COPD treatment?

• Bronchodilators
• Analgesics
• Antidepressants
• Diuretics

Explanation: Answer reason: Short- and long-acting bronchodilators (beta-2 agonists and anticholinergics) improve expiratory flow, reduce air trapping, and relieve dyspnea, making them the main drug group used. Inhaled corticosteroids may be added for selected patients (e.g., frequent exacerbations) but are not the primary class across COPD. Analgesics, antidepressants, and diuretics do not treat the underlying airflow obstruction and are used only for comorbid conditions or specific complications.

What is the primary use of macrolide antibiotics?

• Treatment of urinary tract infections
• Treatment of skin and soft tissue infections
• Treatment of respiratory tract infections
• Treatment of gastrointestinal infections

Explanation: Answer reason: g., azithromycin, clarithromycin, erythromycin) inhibit bacterial protein synthesis at the 50S ribosomal subunit and are especially useful for common respiratory pathogens, including atypicals such as Mycoplasma, Chlamydophila, and Legionella. They are widely used for community-acquired pneumonia, bronchitis/exacerbations of COPD, and upper respiratory infections when bacterial coverage is needed or in penicillin allergy. In contrast, uncomplicated UTIs are more often caused by Enterobacterales (e.g., E. coli), for which macrolides have poor activity and are not first-line. While they can be used for some skin/soft tissue infections, that is not their primary or most characteristic clinical use.

Which drug is a dopamine agonist used in Parkinson’s disease?

• Pramipexole
• Ibuprofen
• Aspirin
• Simvastatin

Explanation: Answer reason: Pramipexole is a non-ergot dopamine agonist (primarily D2/D3) that directly stimulates dopamine receptors and is commonly used for Parkinson’s disease and restless legs syndrome. Ibuprofen and aspirin are NSAIDs used for pain/inflammation and do not have dopamine receptor agonist activity. Simvastatin is an HMG-CoA reductase inhibitor used for hyperlipidemia, not for dopaminergic therapy.

Which drug is an NSAID (Non-Steroidal Anti-Inflammatory Drug)?

• Ibuprofen
• Captopril
• Simvastatin
• Metoprolol

Explanation: Answer reason: The correct choice fits this mechanism and is a common over-the-counter NSAID used for mild to moderate pain and inflammatory conditions. Captopril is an ACE inhibitor used for hypertension and heart failure, not an anti-inflammatory analgesic. Simvastatin is a statin for hyperlipidemia, and metoprolol is a beta-blocker for cardiovascular indications, so neither matches the NSAID class.

Drug of choice in pregnancy to treat hypertension ...?

• Methylcobalamine
• Methyldopa
• Metyrapone
• Metolazone

Explanation: Answer reason: This medication has a long track record for chronic hypertension in pregnancy and lowers blood pressure via central alpha-2 agonism without reducing uteroplacental perfusion in typical use. The other options are not standard antihypertensives for pregnancy: methylcobalamine is vitamin B12, metyrapone is used in adrenal testing/Cushing’s evaluation, and metolazone is a diuretic generally not first-line in pregnancy due to volume depletion concerns. Therefore it is the best choice among the listed options.

What is the main therapeutic use of atorvastatin?

• Treatment of hyperlipidemia
• Management of diabetes
• Control of seizures
• Treatment of hypertension

Explanation: Answer reason: This drug is primarily used to treat hyperlipidemia and to reduce atherosclerotic cardiovascular risk. Diabetes management is addressed with antidiabetic agents, not lipid-lowering therapy. Seizure control and hypertension treatment require anticonvulsants and antihypertensives, respectively, which are different pharmacologic classes with different targets.

What is the primary side effect of beta-blockers?

• Hyperglycemia
• Bradycardia
• Hypertension
• Insomnia

Explanation: Answer reason: This effect is both expected and dose-limiting, so clinically significant slowing of the pulse is a primary adverse effect to monitor. Hypertension is opposite the intended therapeutic effect, and while sleep disturbance can occur with some agents, it is not the primary class effect. Hyperglycemia is not typical; more relevant is masking of hypoglycemia symptoms in diabetics.

What is the primary side effect of levothyroxine?

• Hyperthyroidism
• Bradycardia
• Hypertension
• Drowsiness

Explanation: Answer reason: This leads to increased metabolic and sympathetic activity, commonly causing symptoms like palpitations, tremor, heat intolerance, weight loss, and anxiety. Bradycardia and drowsiness are more consistent with untreated hypothyroidism rather than excessive thyroid hormone replacement. Hypertension can occur from increased adrenergic tone, but it is better captured as part of the broader primary adverse effect of hyperthyroid/overreplacement manifestations.

Which drug is a potassium-sparing diuretic?

• Spironolactone
• Furosemide
• Hydrochlorothiazide
• Bumetanide

Explanation: Answer reason: This medication is an aldosterone receptor antagonist, so it promotes sodium and water excretion while retaining potassium, creating a hyperkalemia risk. In contrast, loop diuretics increase potassium loss, and thiazide diuretics also commonly cause hypokalemia. Recognizing the diuretic class and its characteristic electrolyte effect is the key discriminator among the choices.

A patient on rifampin notices orange discoloration of urine and tears. This is?

• Allergic reaction
• Harmless and expected
• Sign of hepatotoxicity
• Renal failure

Explanation: Answer reason: This is a predictable, benign effect that should be anticipated and taught to support adherence. It is not an allergic reaction unless accompanied by symptoms like rash, wheeze, or angioedema. Hepatotoxicity is suggested instead by jaundice, right upper quadrant pain, dark urine with pale stools, or elevated liver enzymes, and renal failure would present with decreased urine output and rising creatinine rather than simple orange discoloration.

What is the primary use of metformin?

• Treatment of diabetic neuropathy
• Treatment of diabetic retinopathy
• Treatment of diabetic nephropathy
• Treatment of hyperglycemia

Explanation: Answer reason: Its main clinical purpose is glycemic control rather than direct treatment of microvascular complications. While better glucose control can help reduce risk or progression of complications over time, it does not treat established neuropathy, retinopathy, or nephropathy as a primary indication. Therefore the option that best reflects its primary use is control of elevated blood glucose.

How do penicillins like amoxicillin function?

• Inhibition of DNA gyrase
• Blockade of calcium channels
• Activation of beta-adrenergic receptors
• Inhibition of bacterial cell wall synthesis

Explanation: Answer reason: This weakens the wall and leads to osmotic lysis, making the effect bactericidal and most effective in actively dividing organisms. In contrast, DNA gyrase inhibition is a fluoroquinolone mechanism, not a penicillin mechanism. Calcium-channel blockade and beta-adrenergic activation are human cardiovascular/bronchodilator mechanisms and do not describe antibiotic action.

What is the main therapeutic use of losartan?

• Control of blood glucose
• Prevention of blood clots
• Treatment of hypertension
• Management of diabetes

Explanation: Answer reason: This directly targets the pathophysiology of essential hypertension and is the primary labeled therapeutic use of this medication. Options involving glucose control/diabetes management refer to antidiabetic drug classes (e.g., insulin, metformin, GLP-1 agonists) rather than ARBs. Prevention of blood clots is the role of antiplatelets/anticoagulants (e.g., aspirin, heparin, DOACs), not ARBs.

What is the potential risk of long-term use of CNS depressants?

• Addiction
• Hallucinations
• Seizures
• Memory loss

Explanation: Answer reason: Chronic use often leads to escalating doses to achieve the same sedative/anxiolytic effect, reinforcing misuse. Abrupt discontinuation after dependence can cause withdrawal (sometimes including seizures), but that is a consequence of dependence rather than the primary long-term risk being tested here. Hallucinations are not the typical hallmark risk, and while cognitive impairment can occur, the most classically emphasized long-term hazard is dependence/addiction.

Dry mouth aur urinary retention kis wajah se hota hai?

• H2 blockade
• Anticholinergic effect
• Dopamine block
• Serotonin inhibition

Explanation: Answer reason: Decreased salivary gland secretion leads to xerostomia (dry mouth). In the urinary tract, reduced detrusor contraction and relatively increased sphincter tone impair bladder emptying, causing urinary retention. By contrast, H2 blockade mainly affects gastric acid secretion and does not typically produce this paired symptom cluster.

Which chemotherapy agent causes hemorrhagic cystitis?

• Bleomycin
• Vincristine
• Methotrexate
• Cyclophosphamide

Explanation: Answer reason: This adverse effect is most strongly associated with cyclophosphamide (and ifosfamide) and is prevented/mitigated with aggressive hydration and mesna. Bleomycin is linked to pulmonary toxicity, vincristine to peripheral neuropathy/ileus, and methotrexate to mucositis and myelosuppression rather than bladder hemorrhage. Therefore the agent most directly implicated is the alkylator listed.

Which of the following drugs is used to treat Parkinson's disease?

• Ibuprofen
• Metformin
• Levodopa
• Aspirin

Explanation: Answer reason: The most effective symptomatic therapy is to increase central dopamine signaling; levodopa is a dopamine precursor that crosses the blood–brain barrier and is converted to dopamine in the CNS. This directly improves core motor symptoms such as bradykinesia and rigidity. By contrast, ibuprofen and aspirin are NSAIDs for pain/inflammation, and metformin is an antihyperglycemic for type 2 diabetes, none of which target dopamine deficiency.

Second generation antihistamines ka main advantage kya hai?

• Strong sedation
• Less sedation
• Short half-life
• IV use only

Explanation: Answer reason: This makes them less likely to produce drowsiness and impaired psychomotor performance compared with first-generation agents. Sedation is therefore not an advantage of these drugs but a key drawback of older antihistamines. Their half-life is often longer (allowing once-daily dosing), and they are not restricted to IV-only use.

Which antibiotic can cause tendon rupture?

• Macrolides
• Aminoglycosides
• Fluoroquinolones
• Tetracyclines

Explanation: Answer reason: The risk is higher in older adults, patients taking systemic corticosteroids, and transplant recipients, so new tendon pain/swelling warrants stopping the drug and avoiding exercise of the affected tendon. Macrolides more commonly cause QT prolongation and GI upset rather than tendon injury. Aminoglycosides are primarily linked to nephrotoxicity and ototoxicity, and tetracyclines to teeth discoloration and photosensitivity.

Which drug is a dopamine agonist used in Parkinson's disease?

• Pramipexole
• Ibuprofen
• Simvastatin
• Aspirin

Explanation: Answer reason: A direct dopamine agonist binds dopamine receptors (especially D2/D3) to mimic dopamine activity even when endogenous dopamine is low. Pramipexole fits this mechanism and is used as monotherapy in early disease or adjunct to levodopa in advanced disease. In contrast, ibuprofen and aspirin are NSAIDs and simvastatin is a statin; none act as dopamine receptor agonists.

What is the primary side effect of NSAIDs?

• Bradycardia
• Drowsiness
• Hypokalemia
• Gastrointestinal bleeding

Explanation: Answer reason: Loss of mucosal protection predisposes to gastritis, ulceration, and clinically important upper GI hemorrhage, making this the key and most tested adverse effect. Risk increases with higher dose, longer duration, prior peptic ulcer disease, concurrent corticosteroids/anticoagulants, and older age. By contrast, drowsiness and bradycardia are not characteristic primary NSAID toxicities, and electrolyte issues like hypokalemia are not typical (renal effects more often involve sodium retention and hyperkalemia).

The drug that can cause gray baby syndrome in neonates is?

• Gentamicin
• Vancomycin
• Chloramphenicol
• Linezolid

Explanation: Answer reason: Neonates have immature UDP-glucuronyl transferase activity, so serum levels can rise and cause vomiting, hypothermia, cyanosis/ashen-gray discoloration, hypotension, and cardiovascular collapse. This classic toxicity is associated with chloramphenicol exposure in infants (and can occur from direct dosing or transplacental/breastmilk transfer). By contrast, gentamicin and vancomycin are primarily linked to nephrotoxicity/ototoxicity (and vancomycin can cause infusion-related reactions), not the gray baby presentation.

Which drug is commonly used to treat Type 2 Diabetes?

• Warfarin
• Metformin
• Digoxin
• Salbutamol

Explanation: Answer reason: Type 2 diabetes is primarily characterized by insulin resistance, so first-line therapy commonly targets improving insulin sensitivity and lowering hepatic glucose production. This medication reduces gluconeogenesis in the liver and improves peripheral insulin sensitivity, helping lower fasting and postprandial glucose without routinely causing hypoglycemia when used alone. In contrast, an anticoagulant is used to prevent and treat thromboembolism, a cardiac glycoside is used for certain heart failure/arrhythmia indications, and a beta-2 agonist is used for bronchospasm. Therefore, the only option that directly treats type 2 diabetes is the selected one.

What is the main use of beta-blockers?

• Treatment of asthma
• Treatment of diabetes
• Treatment of seizures
• Treatment of hypertension
