病人因急性肺水腫被處方靜脈注射利尿劑 Furosemide。護理師給藥前應優先確認哪項檢驗數值？
A client is prescribed intravenous furosemide for acute pulmonary edema. Which laboratory value should the nurse prioritize reviewing prior to administration?
- APotassium level✓ 正解鉀離子濃度
- BSerum albumin血清白蛋白
- CBlood glucose血糖
- DHemoglobin血紅素
— Explanation · 中文詳解 —
Furosemide 為環利尿劑（Loop diuretic），會透過尿液排出過多鉀離子，長期使用極易導致低血鉀，引發心律不整。給藥前評估鉀離子濃度是預防致命性心律失常的核心步驟，若血鉀低於正常範圍應暫停給藥並通知醫師。
Furosemide is a loop diuretic that significantly increases potassium excretion, making hypokalemia a major risk. Low potassium levels can precipitate life-threatening cardiac arrhythmias, especially in a client with acute pulmonary edema. Therefore, reviewing the serum potassium level is the priority assessment before administering the medication to ensure patient safety.
✦ 台美臨床差異
台美均嚴格執行給藥前電解質核對，但美國常有護理師主導的電子給藥提醒系統自動鎖定低血鉀處方。
