一位心臟衰竭病人被處方使用 Furosemide。護理師應最密切監測哪個實驗室數值？
A client with heart failure is prescribed furosemide. The nurse should monitor which laboratory value most closely?
- ASerum potassium✓ 正解血清鉀
- BSerum sodium血清鈉
- CSerum creatinine血清肌酸酐
- DBlood urea nitrogen (BUN)尿素氮 (BUN)
— Explanation · 中文詳解 —
Furosemide 為利尿劑，會促進鈉、鉀、氯離子及水分排出，其中低血鉀（Hypokalemia）是常見且可能危及生命的副作用，需密切監測。BUN 和 Creatinine 雖也可能受影響，但鉀離子監測是首要考量。
Furosemide is a diuretic that promotes the excretion of sodium, potassium, chloride, and water. Hypokalemia is a common and potentially life-threatening side effect that requires close monitoring. Although BUN and creatinine may also be affected, monitoring potassium is the primary concern.
✦ 台美臨床差異
美國常有藥物專責護理師或臨床藥師協助監測藥物副作用；台灣則由 RN 執行，需較全面的藥理知識。
