— Explanation · 中文詳解 —
Spironolactone 為保鉀利尿劑（Potassium-sparing diuretic）。其作用機轉會抑制醛固酮，導致鉀離子滯留，因此容易發生高血鉀症。護理重點在於監測鉀離子水平，並提醒病人避免攝取含鉀替代鹽（Salt substitutes）。
Spironolactone is a potassium-sparing diuretic that blocks aldosterone, causing potassium retention and risk of hyperkalemia. The nurse must closely monitor serum potassium and instruct the client to avoid potassium-containing salt substitutes and high-potassium supplements.
