A client is taking Furosemide for heart failure. Which of the following laboratory tests should the nurse monitor to assess for an adverse effect of this medication?

  • A. Serum potassium.
  • B. Serum calcium.
  • C. Serum sodium.
  • D. Serum magnesium.
Correct Answer: A

Rationale: Furosemide, a loop diuretic commonly used in heart failure, can cause hypokalemia (low potassium levels) as a side effect. Monitoring serum potassium levels is crucial to detect and prevent complications associated with low potassium levels, such as cardiac arrhythmias. Therefore, the nurse should prioritize assessing the client's serum potassium levels regularly while on Furosemide.
