Potential for Complications Practice Test 4
A client with diverticulitis is admitted with nausea, vomiting, and dehydration. Which finding suggests a complication of diverticulitis?
- Pain in the left lower quadrant
- Boardlike abdomen
- Low-grade fever
- Abdominal distention
Explanation: Answer reason: A boardlike abdomen indicates peritoneal irritation from perforation, a serious complication of diverticulitis. LLQ pain and low-grade fever are typical of uncomplicated diverticulitis; distention is nonspecific.
A client with otosclerosis is scheduled for a stapedectomy. Which finding suggests a complication involving the seventh cranial nerve?
- Diminished hearing
- Sensation of fullness in the ear
- Inability to move the tongue side to side
- Changes in facial sensation
Explanation: Answer reason: Injury to the facial (VII) nerve is a known complication of stapedectomy and may present with abnormal facial nerve function. Of the options, facial changes best indicate VII involvement; tongue movement is CN XII, and diminished hearing/fullness are ear symptoms not specific to CN VII.
The nurse is caring for a client following the reimplantation of the thumb and index finger. Which finding should be reported to the physician immediately?
- Temperature of 100°F
- Coolness and discoloration of the digits
- Complaints of pain
- Difficulty moving the digits
Explanation: Answer reason: After digit reimplantation, signs of vascular compromise must be reported immediately. Cool, discolored digits indicate impaired perfusion/ischemia, which threatens graft viability. Low-grade fever, pain, or limited movement are expected postoperative findings and less urgent.
A client with primary sclerosing cholangitis has received a liver transplant. The nurse should give priority to assessing the client for complications. Which findings are associated with an acute rejection of the new liver?
- Increased jaundice and prolonged prothrombin time
- Fever and foul-smelling bile drainage
- Abdominal distention and clay-colored stools
- Increased uric acid and increased creatinine
Explanation: Answer reason: Acute liver graft rejection impairs bile excretion and hepatic synthetic function, producing jaundice and a prolonged PT/INR. Fever with foul bile suggests infection, clay-colored stools are nonspecific, and elevated uric acid/creatinine indicate renal issues, not liver rejection.
What is the primary concern for a patient with a junctional rhythm?
- Risk of stroke
- Heart failure
- Insufficient cardiac output
- Hypoxia
Explanation: Answer reason: Junctional rhythm originates in the AV junction, often with a slower rate and loss of effective atrial kick, which can reduce stroke volume and lead to decreased cardiac output. Stroke risk is more tied to atrial fibrillation; heart failure and hypoxia are potential downstream effects, not the primary immediate concern.
Prerequisites of Vaginal Birth After Caesarean Section (VBAC) in Ethiopia?
- Only one previous transverse lower segment caesarean, Singleton, vertex, less than 4000g estimated weight and adequate pelvic capacity; no pelvic contraction
- Spontaneous labor onset; no oxytocin use and no other significant obstetric complications e.g. post term, APH, IUGR, preeclampsia etc
- No documented fetal distress, Conducted in a facility equipped and staffed for conducting a caesarean and Maternal consent
- All are true
Explanation: Answer reason: Each listed criterion is a standard safety requirement for attempting VBAC: single prior low-transverse CS with singleton cephalic fetus and adequate pelvis, EFW <4 kg, spontaneous labor without augmentation, absence of complicating obstetric conditions or fetal distress, delivery in a facility capable of emergency CS, and informed maternal consent.
Which patient is most susceptible for acquiring secondary stomatitis?
- An AIDs patient suffering from pneumonia
- An 65 y/o obese female
- A 45 y/o male suffering from colon cancer
- A 50 y/o male with CHF
Explanation: Answer reason: Secondary stomatitis commonly results from opportunistic infections (e.g., Candida) in immunocompromised patients; AIDS confers the greatest immunosuppression among the options, making this patient most susceptible.
For a client with hepatic cirrhosis who has altered clotting mechanisms, which intervention would be most important?
- Allowing complete independence of mobility
- Administering antibiotics as prescribed
- Applying pressure to injection sites
- Increasing nutritional intake
Explanation: Answer reason: Cirrhosis impairs synthesis of clotting factors, increasing bleeding risk. Applying firm pressure after injections directly prevents bleeding. The other options do not address immediate bleeding risk; antibiotics are unrelated, independence of mobility may increase risk of injury/bleeding, and nutrition is a longer-term measure.
The nurse is caring for the patient following removal of a large posterior oral lesion. The priority nursing measure would be to?
- Maintain a patent airway
- Perform meticulous oral care every 2 hours
- Ensure that the incisional area is kept as dry as possible
- Assess the client frequently for pain
Explanation: Answer reason: After posterior oral surgery, edema or bleeding can obstruct the airway. Using ABC priority, maintaining a patent airway is the immediate priority over oral care, dryness of incision, or pain assessment.
The nurse is caring for the client with a mastectomy. Which action would be contraindicated?
- Taking the blood pressure in the side of the mastectomy
- Elevating the arm on the side of the mastectomy
- Positioning the client on the unaffected side
- Performing a dextrostix on the unaffected side
Explanation: Answer reason: After mastectomy, the affected arm should not be used for BP, venipuncture, or finger sticks to prevent lymphedema and impaired circulation. Elevating the affected arm and using the unaffected side are appropriate.
The client is receiving peritoneal dialysis. If the dialysate returns cloudy, the nurse should?
- Document the finding
- Send a specimen to the lab
- Strain the urine
- Obtain a complete blood count
Explanation: Answer reason: Cloudy peritoneal effluent indicates possible peritonitis. The priority is to obtain and send a dialysate specimen for culture and analysis to confirm infection. Documentation alone delays care; straining urine is irrelevant; a CBC is secondary.
The nurse is caring for a client scheduled for removal of the pituitary gland. The nurse should be particularly alert for?
- Nasal congestion
- Abdominal tenderness
- Muscle tetany
- Oliguria
Explanation: Answer reason: Pituitary removal is commonly via a transsphenoidal (nasal) approach; nasal infection/URI increases postoperative complication risk (e.g., meningitis, CSF leak). Therefore the nurse should be alert for nasal congestion. The other findings are not expected: DI causes polyuria (not oliguria) and tetany relates to parathyroid, not pituitary; abdominal tenderness is unrelated.
A client is admitted to the unit 2 hours after an injury with second-degree burns to the face, trunk, and head. The nurse would be most concerned with the client developing what?
- Hypovolemia
- Laryngeal edema
- Hypernatremia
- Hyperkalemia
Explanation: Answer reason: Facial/head burns raise immediate risk for inhalation injury and rapid airway swelling. Within hours post-burn, laryngeal edema can obstruct the airway and is the highest-priority concern.
The client is admitted following repair of a fractured tibia and cast application. Which nursing assessment should be reported to the doctor?
- Pain beneath the cast
- Warm toes
- Pedal pulses weak and rapid
- Paresthesia of the toes
Explanation: Answer reason: Paresthesia suggests neurovascular compromise/compartment syndrome after casting and requires immediate provider notification. Pain under a new cast can be expected, warm toes are normal, and the phrasing of weak and rapid pedal pulses is less specific; early nerve ischemia is best indicated by paresthesia.
Which client is at risk for opportunistic diseases such as pneumocystis pneumonia?
- The client with cancer who is being treated with chemotherapy
- The client with Type I diabetes
- The client with thyroid disease
- The client with Addison's disease
Explanation: Answer reason: Pneumocystis pneumonia is an opportunistic infection occurring primarily in immunocompromised clients. Chemotherapy causes significant immunosuppression (e.g., neutropenia), making these clients highest risk; the other conditions do not confer comparable opportunistic infection risk.
A priority nursing diagnosis for a child being admitted from surgery following a tonsillectomy is?
- Body image disturbance
- Impaired verbal communication
- Risk for aspiration
- Pain
Explanation: Answer reason: Post-tonsillectomy, highest priority is maintaining airway and preventing aspiration from blood and secretions while sedated; this risk outweighs pain or communication concerns.
The client is having fetal heart rates of 100–110 beats per minute during the contractions. The first action the nurse should take is to?
- Apply an internal monitor
- Turn the client to her side
- Get the client up and walk her in the hall
- Move the client to the delivery room
Explanation: Answer reason: FHR of 100–110 bpm during contractions suggests fetal compromise from uteroplacental insufficiency. The priority is to improve uterine perfusion and fetal oxygenation by turning the client to her side. Monitoring, ambulation, or moving to the delivery room do not address the immediate cause.
The nurse is caring for a client with systemic lupus erythematosis (SLE). The major complication associated with systemic lupus erythematosis is?
- Nephritis
- Cardiomegaly
- Desquamation
- Meningitis
Explanation: Answer reason: Renal involvement (lupus nephritis) is the most significant complication of SLE and a major cause of morbidity and mortality. Cardiomegaly, desquamation, and meningitis are not typical primary complications.
The nurse is caring for an infant following a cleft lip repair. While comforting the infant, the nurse should avoid?
- Holding the infant
- Offering a pacifier
- Providing a mobile
- Offering sterile water
Explanation: Answer reason: After cleft lip repair, sucking actions can stress or disrupt the suture line. Pacifiers promote sucking and should be avoided; holding, a mobile, or small amounts of sterile water do not place tension on the repair.
A client has rectal cancer and is scheduled for an abdominal perineal resection. What should be the priority nursing care during the post-op period?
- Teaching how to irrigate the ileostomy
- Stopping electrolyte loss in the incisional area
- Encouraging a high-fiber diet
- Facilitating perineal wound drainage
Explanation: Answer reason: The highest post-op risk is perineal wound infection or abscess; ensuring proper drainage prevents complications.
The nurse assesses several post partum women in the clinic. Which of the following women is at HIGHEST risk for puerperal infection?
- 12 hours post partum, temperature of 100.4 F since delivery
- 2 days post partum, temperature of 101.2 F this morning
- 3 days post partum, temperature of 100.8 F the past 2 days
- 4 days post partum, temperature of 100 F since delivery
Explanation: Answer reason: Postpartum infection is suggested by a maternal temperature of 100.4°F or higher on two successive days, excluding the first 24 hours after birth. Option C meets this criterion (100.8°F for the last 2 days at 3 days postpartum). Others do not.
A client is admitted for COPD. Which of the following symptoms would require the nurse's IMMEDIATE attention?
- Nausea and vomiting
- Restlessness and confusion
- Low-grade fever and cough
- Irritating cough and liquefied sputum
Explanation: Answer reason: Restlessness and confusion indicate hypoxemia and impending respiratory failure in COPD, requiring immediate assessment and intervention (e.g., ABGs, oxygen support).
While caring for a client with infective endocarditis, the nurse must be alert for signs of pulmonary embolism. Which of the following assessment findings suggests this complication?
- Positive Homan's sign
- Fever and chills
- Dyspnea and cough
- Sensory impairment
Explanation: Answer reason: Pulmonary embolism commonly presents with acute dyspnea and cough (often with pleuritic chest pain). Homan's sign suggests DVT, fever and chills indicate infection, and sensory impairment is unrelated.
The nurse observes a staff member caring for a client with a left unilateral mastectomy. The nurse would intervene if she notices the staff member is?
- Advising client to restrict sodium intake
- Taking the blood pressure in the left arm
- Elevating her left arm above heart level
- Compressing the drainage device
Explanation: Answer reason: After mastectomy, avoid blood pressure, venipunctures, and injections on the affected arm to prevent lymphedema. Elevation and JP drain compression are appropriate; sodium restriction may reduce edema but is not harmful.
A six month-old infant who is being treated for developmental dysplasia of the hip has been placed in a hip spica cast. The nurse should teach the parents?
- That gently rubbing the skin with a cotton swab will relieve itching
- To place his favorite books and push-pull toys in his crib
- To check frequently for swelling in the baby's feet
- To turn the baby every 2 hours utilizing the abduction stabilizer bar
Explanation: Answer reason: Hip spica casts can impair circulation; parents should monitor distal neurovascular status. Swelling in the feet signals compromised perfusion. Inserting objects to scratch is unsafe, push–pull toys are not appropriate in the crib, and the abduction bar should not be used to turn the infant.
A nurse caring for premature newborns in an intensive care setting carefully monitors oxygen concentration. The MOST important reason for this assessment is to prevent?
- Intraventricular hemorrhage
- Retinopathy of prematurity
- Bronchial pulmonary dysplasia
- Necrotizing enterocolitis
Explanation: Answer reason: Excess oxygen in premature infants can cause retinal vaso-obliteration and neovascularization leading to retinopathy of prematurity; careful monitoring of oxygen concentration helps prevent this complication.
While caring for a child with Reye's Syndrome, the nurse should give which of the following the HIGHEST priority?
- Monitoring intake and output
- Providing good skin care
- Assessing level of consciousness
- Assisting with range of motion
Explanation: Answer reason: Reye's syndrome can cause cerebral edema and increased intracranial pressure; the earliest and most critical indicator is a change in level of consciousness, making frequent neurological assessment the top priority.
A client with chronic congestive heart failure should be instructed to contact the home health nurse if which of the following occurs?
- Weight gain of 2 pounds or more in a 48 hour period
- Urinating 4-5 times each day
- A decrease in appetite
- Appearance of non-pitting ankle edema
Explanation: Answer reason: Rapid weight gain signals acute fluid retention and worsening heart failure; patients are taught to report a gain of about 2–3 lb in 24–48 hours. The other options are not reliable indicators of decompensation.
A hospitalized child suddenly has a seizure while his family is visiting. The nurse notes whole body rigidity followed by general jerking movements. The child vomits immediately after the seizure. A PRIORITY nursing diagnosis for the child is?
- High risk for infection
- Altered family processes related to chronic illness
- Fluid volume deficit related to vomiting
- Risk for aspiration related to loss of consciousness
Explanation: Answer reason: After a tonic–clonic seizure with vomiting, the immediate priority is airway protection; decreased consciousness increases the risk of aspiration.
A two month-old infant has both a cleft lip and palate which will be repaired in stages. In the immediate postoperative period for a cleft lip repair, which one of the following nursing measures should be PRIORITY?
- Utilize elbow restraints at all times
- Initiate formula/breast feedings when alert
- Teach parents to cleanse the suture line with alcohol
- Position the infant on the back after feedings
Explanation: Answer reason: Immediate post-op care focuses on protecting the suture line. Elbow restraints prevent the infant from rubbing or traumatizing the repaired lip. Feeding resumption is not the top priority, alcohol should not be used on the incision, and positioning is helpful but secondary to protecting the operative site.
A client is receiving oxygen therapy via a nasal cannula. When providing nursing care, which of the following interventions would be appropriate?
- Determine that adequate mist is supplied
- Inspect the nares and ears for skin breakdown
- Lubricate the tips of the cannula before insertion
- Maintain sterile technique when handling cannula
Explanation: Answer reason: Oxygen via nasal cannula can dry mucosa and the tubing can exert pressure on nares and ears, risking skin breakdown; frequent inspection is appropriate. Adequate mist is not relevant to nasal cannula, lubrication of tips is not indicated and petroleum products increase fire risk, and sterile technique is unnecessary for a nasal cannula.
A client was re-admitted to the hospital following a recent skull fracture. Which of the following symptoms requires the nurse's IMMEDIATE attention?
- Lethargy
- Agitation
- Ataxia
- Hearing loss
Explanation: Answer reason: Lethargy indicates decreased level of consciousness, an early sign of rising intracranial pressure after head injury, and requires immediate intervention. Agitation, ataxia, or hearing loss are less emergent.
The nurse is caring for a client on complete bed rest. Which action by the nurse is MOST important in preventing the formation of deep vein thrombosis?
- Elevate the foot of the bed
- Apply knee high support stockings
- Encourage passive exercises
- Prevent pressure at back of knees
Explanation: Answer reason: Avoiding pressure in the popliteal area prevents compression of vessels, reduces venous stasis, and decreases the risk of DVT in bedrest patients.
The nurse is caring for a post-surgical client at risk for developing deep vein thrombosis. Which of the following is an effective preventive measure?
- Place pillows under the knees
- Use elastic stockings continuously
- Encourage range of motion and ambulation
- Massage the legs twice daily
Explanation: Answer reason: Early mobility promotes venous return and reduces venous stasis, decreasing DVT risk. Pillows under knees can impede flow, continuous stockings require periodic removal/assessment and are not sufficient alone, and leg massage could dislodge a clot.
The nurse is teaching parents about the treatment plan for a 2 week-old infant with Tetralogy of Fallot. While awaiting future surgery, the nurse instructs the parents to IMMEDIATELY report?
- Loss of consciousness
- Feeding problems
- Poor weight gain
- Fatigue with crying
Explanation: Answer reason: Loss of consciousness signals severe hypoxia/anoxia in Tetralogy of Fallot and is an emergency requiring immediate medical attention; the other findings are concerning but not emergent.
A client has just returned to the medical-surgical unit following a segmental lung resection. After assessing the client, the FIRST nursing action would be to?
- Administer pain medication
- Suction excessive tracheobronchial secretions
- Assist client to turn, cough and deep breathe
- Monitor oxygen saturation
Explanation: Answer reason: Post-thoracic surgery clients often have copious secretions; maintaining a patent airway is the top priority. Suctioning addresses immediate airway patency before interventions like pain medication, TCDB, or monitoring.
The nurse is caring for a client with acute pancreatitis. Which of the following, after pain management, should be included in the plan of care?
- Cough and deep breathe every two hours
- Place the client in contact isolation
- Provide a diet high in protein
- Institute seizure precautions
Explanation: Answer reason: Acute pancreatitis can cause shallow respirations and risk of atelectasis/pneumonia from diaphragmatic irritation and pain. Encouraging coughing and deep breathing every two hours helps prevent pulmonary complications. Contact isolation and seizure precautions are not indicated, and during acute pancreatitis patients are usually NPO, not on high-protein diets.
In providing care to acutely ill pediatric clients, the nurse should recognize that the child at HIGHEST risk for cardiac arrest is the individual experiencing?
- Congenital cardiac defects
- An acute febrile illness
- Prolonged hypoxemia
- Severe multiple trauma
Explanation: Answer reason: In children, cardiac arrest most commonly follows respiratory failure; prolonged hypoxemia leads to bradycardia and subsequent arrest.
The client returns to the recovery room following repair of an abdominal aneurysm. Which finding would require further investigation?
- Pedal pulses regular
- Urinary output 20mL in the past hour
- Blood pressure 108/50
- Oxygen saturation 97%
Explanation: Answer reason: Post–abdominal aortic aneurysm repair, urine output should be at least 30 mL/hr. Output of 20 mL/hr suggests decreased renal perfusion or graft-related complications and warrants prompt investigation. The other findings are acceptable.
Which sign suggests that a male client with syndrome of inappropriate antidiuretic hormone (SIADH) secretion is experiencing complications?
- Neck vein distension
- Weight loss
- Tetanic contractions
- Polyurea
Explanation: Answer reason: SIADH causes water retention and dilutional hyponatremia with decreased urine output. A complication is fluid volume excess, indicated by neck vein distension. Weight loss and polyuria are inconsistent with SIADH; tetany is related to hypocalcemia, not typical of SIADH.
Which activity should the nurse encourage the client to avoid when there is a risk for increased intracranial pressure (ICP)?
- Deep breathing
- Turning
- Coughing
- Passive range-of-motion (ROM) exercises
Explanation: Answer reason: Coughing increases intrathoracic pressure and can raise intracranial pressure, so it should be avoided. Deep breathing, turning, and passive ROM can be done carefully without significantly increasing ICP.
A client undergoing long-term peritoneal dialysis at home is experiencing reduced outflow from the dialysis catheter; the nurse should inquire whether the client has which condition?
- Diarrhea
- Vomiting
- Flatulence
- Constipation
Explanation: Answer reason: Constipation can displace or compress the peritoneal dialysis catheter and impede dialysate outflow; assessing and treating constipation restores flow.
A client calls the nurse with a complaint of sudden deep throbbing leg pain. What is the appropriate FIRST action by the nurse?
- Suggest isometric exercises
- Maintain the client on bed rest
- Ambulate for several minutes
- Apply ice to the extremity
Explanation: Answer reason: Sudden deep throbbing leg pain suggests deep vein thrombosis. The priority is to prevent embolization by keeping the client on bed rest and notifying the provider; exercise or ambulation could dislodge the clot, and ice is not the first priority action.
A nurse aide is taking care of a 2 year-old child with Wilm's tumor. The nurse aide asks the nurse why there is a sign above the bed that says DO NOT PALPATE THE ABDOMEN? The response by the nurse would be?
- "Touching the abdomen could cause cancer cells to spread."
- "Examining the area would be very painful to the child."
- "Pushing on the stomach might lead to the spread of infection."
- "Placing any pressure on the abdomen may cause bleeding."
Explanation: Answer reason: In Wilms tumor, palpating the abdomen can rupture the tumor capsule and seed malignant cells, so the abdomen should not be palpated.
Immediately following insertion of a central line, the client develops tachycardia, cyanosis and hypotension. The nurse would IMMEDIATELY place the client in the?
- Supine position with head of bed flat
- Trendelenberg position
- Right side position with head of bed 90 degrees
- Left side position with head of bed lowered
Explanation: Answer reason: Symptoms suggest an air embolism after central line insertion. Place the client in left lateral with head lowered (left-sided Trendelenburg) to trap air in the right atrium and prevent it from entering pulmonary circulation.
The nurse is caring for an 87 year-old client with urinary retention. Which of the following should be reported immediately?
- Fecal impaction
- Infrequent voiding
- Stress incontinence
- Burning with urination
Explanation: Answer reason: Fecal impaction can mechanically obstruct the bladder outlet and worsen urinary retention in the elderly, requiring prompt reporting and intervention. The other options are not immediate threats to bladder emptying.
A client with multiple sclerosis plans to begin an exercise program. In addition to discussing the benefits of regular exercise, the nurse should caution the client to avoid activities which?
- Increase the heart rate
- Lead to dehydration
- Are considered aerobic
- May be competitive
Explanation: Answer reason: Heat and dehydration can exacerbate multiple sclerosis symptoms; clients should maintain hydration and avoid activities that could cause dehydration during exercise.
The nurse is giving discharge teaching to a client 7 days post myocardial infarction. He asks the nurse why he must wait 6 weeks before having sexual intercourse. The nurse's BEST response to this question is?
- "You need to regain your strength before attempting such exertion."
- "When you can climb two flights of stairs without problems, it is generally safe."
- "Have a glass of wine to relax you, then you can try to have sex."
- "If you can maintain an active walking program, you will have less risk."
Explanation: Answer reason: After MI, resuming sexual activity is generally safe when the client can tolerate moderate exertion—often assessed by climbing two flights of stairs without symptoms—typically around 6 weeks as scar tissue forms.
As a client is being discharged following resolution of a spontaneous pneumothorax, he tells the nurse that he is now going to Hawaii for a vacation. The nurse would warn him to avoid?
- Surfing
- Scuba diving
- Parasailing
- Swimming
Explanation: Answer reason: Scuba diving exposes the client to significant pressure changes that can precipitate another lung collapse after a spontaneous pneumothorax.
The nurse is assessing a client who has had a spinal cord injury. Which of the following assessment findings would suggest the complication of autonomic dysreflexia?
- Urinary bladder spasm pain.
- Severe pounding headache.
- Tachycardia.
- Severe hypotension.
Explanation: Answer reason: Autonomic dysreflexia typically presents with acute severe hypertension and a pounding headache, often triggered by bladder or bowel irritation. It is associated with bradycardia, not tachycardia, and hypertension rather than hypotension. The bladder spasm is a trigger, not the hallmark assessment finding.
