A patient is prescribed an angiotensin-converting enzyme (ACE) inhibitor for heart failure. Which laboratory parameter should the nurse monitor closely during ACE inhibitor therapy?

  • A. Serum potassium levels
  • B. Serum sodium levels
  • C. Blood glucose levels
  • D. Serum creatinine levels
Correct Answer: A

Rationale: The nurse should monitor serum potassium levels closely during ACE inhibitor therapy because ACE inhibitors can lead to an increase in serum potassium levels, known as hyperkalemia. ACE inhibitors block the conversion of angiotensin I to angiotensin II, which in turn decreases aldosterone secretion. Aldosterone normally acts in the kidneys to reabsorb sodium and water and excrete potassium. Therefore, when aldosterone secretion is decreased due to ACE inhibitor therapy, there can be an increase in potassium retention, potentially leading to hyperkalemia. Monitoring serum potassium levels is essential to prevent complications associated with hyperkalemia, such as cardiac arrhythmias.
