Quizplus · Accepted Answer

Spironolactone is a potassium-sparing diuretic that works by blocking aldosterone receptors, leading to decreased sodium and water reabsorption and increased potassium retention. Therefore, it can cause hyperkalemia (high levels of potassium in the blood), which can lead to ECG changes and muscle weakness.
