A client with a history of chronic kidney disease is scheduled for a CT scan with contrast. Which laboratory value should the nurse review before the procedure?
- A. Serum potassium
- B. Blood urea nitrogen (BUN)
- C. Serum creatinine
- D. Serum glucose
Correct Answer: C
Rationale: Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in assessing kidney function because contrast agents can potentially worsen renal function, leading to contrast-induced nephropathy. Monitoring serum creatinine helps in identifying patients at risk and taking necessary precautions. Serum potassium (Choice A) is important in conditions like hyperkalemia but is not the priority before a contrast CT scan. Blood urea nitrogen (BUN) (Choice B) is another renal function test but is not as specific as serum creatinine for assessing kidney function. Serum glucose (Choice D) is important in monitoring blood sugar levels, especially in diabetic patients, but it is not directly related to the risk of contrast-induced nephropathy in this scenario.

A client with chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which intervention should the nurse implement first?
- A. Administer oxygen therapy as prescribed.
- B. Elevate the head of the bed.
- C. Obtain a sputum culture.
- D. Administer antibiotics as prescribed.
Correct Answer: A
Rationale: In a client with COPD admitted with pneumonia, the priority intervention should be to administer oxygen therapy as prescribed. This is crucial to improve oxygenation, especially in a client with compromised respiratory function. Elevating the head of the bed can help with breathing but is secondary to ensuring adequate oxygenation. Obtaining a sputum culture and administering antibiotics are important steps in the treatment of pneumonia but come after ensuring adequate oxygen supply.
Progressive kyphoscoliosis leading to respiratory distress is evident in a client with muscular dystrophy. Which finding warrants immediate intervention by the nurse?
- A. Extremity muscle weakness.
- B. Bilateral eyelid drooping.
- C. Inability to swallow pills.
- D. Evidence of hypoventilation.
Correct Answer: D
Rationale: The correct answer is D: Evidence of hypoventilation. In a client with muscular dystrophy and progressive kyphoscoliosis, hypoventilation indicates respiratory muscle weakness and can lead to life-threatening respiratory distress. Immediate intervention is crucial to prevent complications. Choices A, B, and C are incorrect because while extremity muscle weakness, bilateral eyelid drooping, and inability to swallow pills are concerning symptoms in muscular dystrophy, evidence of hypoventilation poses a more immediate threat to the client's respiratory status.
Which assessment finding requires immediate intervention for a client receiving enteral feedings via a nasogastric tube?
- A. Auscultate the client's lungs for breath sounds
- B. Check the client's blood glucose level
- C. Monitor the client's bowel sounds
- D. Elevate the head of the bed to 45 degrees
Correct Answer: D
Rationale: Elevating the head of the bed to 45 degrees is crucial for clients receiving enteral feedings via a nasogastric tube to prevent aspiration. Aspiration can lead to serious complications such as pneumonia. Auscultating the client's lungs for breath sounds (choice A) is important but not as urgent as preventing aspiration. Checking the client's blood glucose level (choice B) and monitoring bowel sounds (choice C) are also essential aspects of care for a client receiving enteral feedings, but they do not take precedence over preventing aspiration.
A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which assessment finding requires immediate intervention?
- A. Oxygen saturation of 90%
- B. Respiratory rate of 24 breaths per minute
- C. Use of accessory muscles
- D. Inspiratory crackles
Correct Answer: C
Rationale: The correct answer is C: Use of accessory muscles. In a client with COPD and pneumonia, the use of accessory muscles indicates increased work of breathing and may signal respiratory failure. Immediate intervention is necessary to prevent further deterioration of the respiratory status. Choice A, an oxygen saturation of 90%, though low, may not require immediate intervention as it is above the typical threshold for initiating supplemental oxygen. Choice B, a respiratory rate of 24 breaths per minute, falls within the normal range for an adult and may not be an immediate cause for concern. Choice D, inspiratory crackles, are indicative of fluid in the lungs but may not require immediate intervention unless accompanied by other concerning signs like decreased oxygen saturation or increased respiratory distress.
For the past 24 hours, an antidiarrheal agent, diphenoxylate, has been administered to a bedridden, older client with infectious gastroenteritis. Which finding requires the nurse to take further action?
- A. Tented skin turgor
- B. Decreased bowel sounds
- C. Persistent diarrhea
- D. Dehydration
Correct Answer: A
Rationale: The correct answer is A. Tented skin turgor is a sign of dehydration, which can be exacerbated by the use of antidiarrheals in clients with gastroenteritis. In dehydration, the skin loses its elasticity and becomes less resilient when pinched. Therefore, the nurse should take immediate action upon noticing tented skin turgor to prevent further complications. Choices B, C, and D are incorrect because decreased bowel sounds, persistent diarrhea, and dehydration are expected findings in a client with gastroenteritis who has been administered an antidiarrheal agent.
