Before administering furosemide (Lasix) to a client with heart failure, what is the most important laboratory test result for the nurse to check?

  • A. Potassium level
  • B. Creatinine level
  • C. Cholesterol level
  • D. Blood urea nitrogen
Correct Answer: A

Rationale: The correct answer is to check the potassium level before administering furosemide (Lasix) to a client with heart failure. Furosemide is a loop diuretic that can cause hypokalemia, so it is crucial to assess the potassium level to prevent complications like cardiac arrhythmias associated with low potassium levels.
