Rationale: A serum potassium level of 5.2 mEq/L indicates hyperkalemia. Spironolactone is a potassium-sparing diuretic that can cause potassium retention. Hyperkalemia is a serious condition that can lead to cardiac dysrhythmias. The healthcare professional should withhold the medication and promptly notify the provider to prevent potential complications.
