1. While assessing clients on a medical-surgical unit, which client is at risk for hypokalemia?
- A. Client with pancreatitis who has continuous nasogastric suctioning
- B. Client who is prescribed an angiotensin-converting enzyme (ACE) inhibitor
- C. Client in a motor vehicle crash who is receiving 6 units of packed red blood cells
- D. Client with uncontrolled diabetes and a serum pH level of 7.33
Correct answer: A
Rationale: Continuous nasogastric suctioning can lead to hypokalemia due to the loss of gastric contents rich in potassium. Therefore, a client with pancreatitis who has continuous nasogastric suctioning is at risk for hypokalemia. Option B is incorrect because ACE inhibitors may lead to hyperkalemia, not hypokalemia. Option C is incorrect as receiving packed red blood cells can lead to hyperkalemia due to the potassium content in the blood product. Option D is incorrect because a serum pH level of 7.33 indicates acidosis, which is not directly associated with hypokalemia.
