Nursing Elites

1. A client with a ruptured spleen underwent an emergency splenectomy. Twelve hours later, the client’s urine output is 25 ml/hour. What is the most likely cause?

• A. This is a normal finding after surgery.
• B. Oliguria signals tubular necrosis related to hypoperfusion.
• C. Oliguria signals dehydration and fluid loss.
• D. Urine output of 25 ml/hour is an expected finding after splenectomy.

Correct answer: B

Rationale: Oliguria, or decreased urine output, after surgery can indicate tubular necrosis due to hypoperfusion, which may require intervention to restore renal function. Choice A is incorrect as oliguria is not a normal finding after surgery. Choice C is incorrect because dehydration is less likely in this context compared to tubular necrosis. Choice D is incorrect as a urine output of 25 ml/hour is not expected after splenectomy and should raise concern for renal impairment.

2. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

3. A client with hypertension is being educated on lifestyle changes by a nurse. Which recommendation is the most important to reduce blood pressure?

• A. Increase water intake
• B. Avoid alcohol consumption
• C. Exercise regularly
• D. Reduce sodium intake

Correct answer: D

Rationale: Reducing sodium intake is crucial in managing hypertension as high sodium levels can lead to fluid retention and increased blood pressure. While increasing water intake is beneficial for overall health, reducing sodium has a more significant impact on blood pressure. Regular exercise is important for cardiovascular health but does not have as direct an impact on blood pressure as sodium reduction. Avoiding alcohol is also important, but in terms of managing blood pressure, reducing sodium intake takes precedence.

4. A client who had a subtotal parathyroidectomy two days ago is now preparing for discharge. Which assessment finding requires immediate provider notification?

• A. Afebrile with a normal pulse.
• B. No bowel movement since surgery.
• C. No appetite for breakfast.
• D. A positive Chvostek's sign.

Correct answer: D

Rationale: A positive Chvostek's sign suggests hypocalcemia, which is a post-parathyroidectomy complication and requires prompt treatment. The other options are less urgent: being afebrile with a normal pulse is expected, no bowel movement since surgery can be managed with interventions like early ambulation and stool softeners, and no appetite for breakfast is common postoperatively and can be addressed without immediate provider notification.

5. The nurse is caring for a client in atrial fibrillation. The atrial heart rate is 250, and the ventricular rate is controlled at 75. Which of the following findings is cause for the most concern?

• A. Diminished bowel sounds
• B. Loss of appetite
• C. A cold, pale lower leg
• D. Tachypnea

Correct answer: C

Rationale: A cold, pale lower leg is cause for the most concern as it could indicate compromised blood circulation, potentially leading to serious complications like ischemia or thrombosis. Diminished bowel sounds, loss of appetite, and tachypnea are not directly related to the client's condition in atrial fibrillation and the heart rate discrepancy.
