Question 1

What is the main therapeutic use of tramadol?

Accepted Answer

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.

Question 2

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

Accepted Answer

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.

Question 3

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

Accepted Answer

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.

Question 4

What is a key adverse effect of aminoglycosides like tobramycin?

Accepted Answer

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.

Question 5

How do tetracyclines like doxycycline function?

Accepted Answer

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.

Question 6

What is the contraindication for using aminoglycoside antibiotics?

Accepted Answer

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.

Question 7

What is a key adverse effect of isoniazid?

Accepted Answer

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.

Question 8

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

Accepted Answer

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.

Question 9

What is a common side effect of atenolol?

Accepted Answer

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.

Question 10

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

Accepted Answer

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.

Question 11

What is a key adverse effect of carbamazepine?

Accepted Answer

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.

Question 12

What is a common side effect of azithromycin?

Accepted Answer

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.

Question 13

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

Accepted Answer

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.

Question 14

What is the mechanism of action of anticoagulants?

Accepted Answer

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.

Question 15

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

Accepted Answer

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.

Question 16

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

Accepted Answer

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.

Question 17

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

Accepted Answer

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.

Question 18

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

Accepted Answer

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.

Question 19

How do cephalosporins like cefalexin work?

Accepted Answer

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.

Question 20

The most common indication for electroconvulsive therapy is?

Accepted Answer

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.

Question 21

Which drug is commonly used to control Nausea and Vomiting?

Accepted Answer

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.

Question 22

What is the main use of proton pump inhibitors?

Accepted Answer

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.

Question 23

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

Accepted Answer

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.

Question 24

What is a common side effect of valproic acid?

Accepted Answer

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.

Question 25

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

Accepted Answer

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.

Question 26

What is the mechanism of action of allopurinol?

Accepted Answer

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).

Question 27

What are the potential side effects of laxatives?

Accepted Answer

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.

Question 28

What is the main therapeutic use of tramadol?

Accepted Answer

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.

Question 29

First generation antihistamines ka CNS effect kyon hota hai?

Accepted Answer

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.

Question 30

DEC therapy ke sath antihistamine kyon diya jata hai?

Accepted Answer

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.

Question 31

How do direct thrombin inhibitors like dabigatran work?

Accepted Answer

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.

Question 32

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

Accepted Answer

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.

Question 33

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

Accepted Answer

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.

Question 34

What is the mechanism of action of levodopa?

Accepted Answer

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.

Question 35

What is the primary indication for propranolol?

Accepted Answer

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.

Question 36

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

Accepted Answer

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).

Question 37

What is the primary indication for albuterol?

Accepted Answer

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.

Question 38

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

Accepted Answer

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.

Question 39

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

Accepted Answer

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.

Question 40

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?

Accepted Answer

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.

Question 41

What is the mechanism of action of warfarin?

Accepted Answer

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.

Question 42

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

Accepted Answer

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.

Question 43

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

Accepted Answer

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.

Question 44

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?

Accepted Answer

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.

Question 45

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?

Accepted Answer

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.

Question 46

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

Accepted Answer

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.

Question 47

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?

Accepted Answer

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.

Question 48

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

Accepted Answer

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.

Question 49

Which of the following is an iterative medication?

Accepted Answer

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.

Question 50

What is the primary indication for the use of laxatives?

Accepted Answer

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.
