A patient is diagnosed with hypokalemia. After reviewing the patient's current medications, which drug should the nurse consider that might have contributed to the patient's health problem?
1. corticosteroid
2. thiazide diuretic
3. narcotic
4. muscle relaxer
Correct Answer: 1
Excess potassium loss through the kidneys is often caused by such medications as corticosteroids, potassium-wasting diuretics, amphotericin B, and large doses of some antibiotics. Excessive sodium is lost with the use of thiazide diuretics. Narcotics and muscle relaxers do not typically affect electrolyte balance.
