A client is prescribed furosemide 40 mg IV push. Before administering the medication, which assessment is most critical for the nurse to perform?
- ADaily weight每日體重
- BPeripheral edema周邊水腫
- CBlood pressure血壓
- DSerum potassium level✓ 正解血清鉀濃度
— Explanation · 中文詳解 —
Furosemide 是排鉀利尿劑，長期使用或大劑量推注易導致低血鉀，誘發心律不整。給藥前確認電解質（尤其鉀離子）在安全範圍是避免藥物副作用與致命心律失常的核心指標。其他選項雖為相關評估，但緊急程度不及鉀離子異常可能導致的心電圖變化與生命危險。
Furosemide is a loop diuretic that promotes significant potassium excretion, creating a high risk for hypokalemia and potentially life-threatening cardiac arrhythmias. Therefore, assessing the serum potassium level is the most critical pre-administration safety check to ensure the client is not already at risk for electrolyte imbalance.
✦ 台美臨床差異
美台臨床對於給藥前評估鉀離子皆為標準作業，但台灣較常要求護理師於給藥前同時確認心電圖監測狀態。
