A) Albumin
B) Sodium
C) Potassium

Ans: C
Feedback: Spironolactone (Aldactone) is a potassium-sparing diuretic. Careful monitoring and review of recent potassium levels is important when administering this medication as the patient is at risk for hyperkalemia if experiencing impaired renal function. Albumin, sodium, and creatinine do not require careful monitoring when administering this potassium-sparing diuretic.
