Mannitol
Spironolactone (Aldactone)
Furosemide (Lasix)
Metformin
The Correct Answer is C
A. Mannitol is an osmotic diuretic, and although it can cause dehydration and electrolyte imbalances, it does not specifically cause hypokalemia as a primary side effect.
B. Spironolactone is a potassium-sparing diuretic, so it is less likely to cause hypokalemia. In fact, it can cause hyperkalemia.
C. Furosemide is a loop diuretic that increases urine output and can lead to potassium loss, causing hypokalemia. This is a common complication of loop diuretics.
D. Metformin is an oral antidiabetic medication and is not a diuretic, so it is not associated with hypokalemia.
