The nurse is caring for a client with a history of a hiatal hernia who is receiving Propulsid (cisapride). The nurse should monitor the client for:
- A. Arrhythmias
- B. Hypotension
- C. Constipation
- D. Weight gain
Correct Answer: A
Rationale: Cisapride can prolong the QT interval, risking arrhythmias, requiring cardiac monitoring. Hypotension, constipation, and weight gain are not primary side effects.

A client with myasthenia gravis is admitted in a cholinergic crisis. Signs of of cholinergic crisis include:
- A. Decreased blood pressure and constricted pupils
- B. Increased heart rate and increased respirations
- C. Increased respirations and increased blood pressure
- D. Anoxia and absence of the cough reflex
Correct Answer: A
Rationale: Cholinergic crisis, often from excessive anticholinesterase medication, causes parasympathetic overstimulation, leading to decreased blood pressure and constricted pupils.
A client is receiving peritoneal dialysis. He has been taught to warm the dialyzing fluid prior to instilling it because:
- A. Warmed solution helps keep the body temperature maintained within a normal range during instillation
- B. Warmed solution helps dilate the peritoneal blood vessels
- C. Warmed solution decreases the risk of peritoneal infection
- D. Warmed solution promotes a relaxed abdominal muscle
Correct Answer: B
Rationale: Instilling a cool solution does not significantly lower the body temperature during peritoneal dialysis. Warmed solution does help dilate the peritoneal blood vessels, facilitating the exchange of fluids. Warming the dialysate does not decrease the risk of peritoneal infection. Sterile technique decreases this risk. Relaxing the abdominal muscles does not facilitate peritoneal dialysis.
A newborn infant is exhibiting signs of respiratory distress. Which of the following would the nurse recognize as the earliest clinical sign of respiratory distress?
- A. Cyanosis
- B. Increased respirations
- C. Sternal and subcostal retractions
- D. Decreased respirations
Correct Answer: C
Rationale: Sternal and subcostal retractions are the earliest sign of respiratory distress in newborns, indicating increased ventilatory effort.
The nurse is caring for a client with a history of Addison’s disease. The nurse should expect the client to have:
- A. Hypotension
- B. Hypertension
- C. Hyperglycemia
- D. Weight gain
Correct Answer: A
Rationale: Addison’s disease causes adrenal insufficiency, reducing cortisol and aldosterone, leading to hypotension due to fluid and sodium loss.
A 68-year-old client developed acute respiratory distress syndrome while hospitalized for pneumonia. After a respiratory arrest, an endotracheal tube was inserted. Several days later, numerous attempts to wean him from mechanical ventilation were ineffective, and a tracheostomy was created. For the first 24 hours following tracheostomy, it is important to minimize bleeding around the insertion site. The nurse can accomplish this by:
- A. Deflating the cuff for 10 minutes every other hour instead of 5 minutes every hour
- B. Avoiding manipulation of the tracheostomy including cuff deflation
- C. Reporting any signs of crepitus immediately to the physician
- D. Changing tracheostomy dressing only as necessary using one-half strength hydrogen peroxide to cleanse the site
Correct Answer: B
Rationale: The tracheal cuff should not be deflated within the first 24 hours following surgery. To minimize bleeding, any manipulation, including cuff deflation, should be avoided. Small amounts of crepitus are expected to occur; however, large amounts or expansion of the area of crepitus should be reported to the physician. The tracheostomy site may be changed as often as necessary, but site care should be done with normal saline.
