病人因心衰竭被處方使用速尿靈（Furosemide）。給藥前護理師最優先應進行哪項評估？
A client is prescribed furosemide for heart failure. Which nursing assessment is most important to perform prior to administration?
- ARespiratory rate呼吸頻率
- BBlood urea nitrogen level尿素氮濃度
- CBlood glucose level血糖濃度
- DSerum potassium level✓ 正解血清鉀濃度
— Explanation · 中文詳解 —
速尿靈是一種排鉀利尿劑，長期或高劑量使用容易導致低血鉀，進而引發致命的心律不整。給藥前確認血鉀濃度是否在正常範圍（3.5-5.0 mEq/L）是極為重要的安全評估步驟。C、B、A 雖有臨床意義，但對此藥而言，電解質不平衡的即時危害最大。
Furosemide is a potassium-wasting diuretic, and long-term or high-dose use easily causes hypokalemia, which can precipitate fatal dysrhythmias. Before administration, confirming that the serum potassium level is within the normal range (3.5-5.0 mEq/L) is an extremely important safety assessment step. Although options C, B, and A have clinical significance, for this medication, the immediate threat of electrolyte imbalance is the greatest concern.
✦ 台美臨床差異
在台灣，護理師給予 Furosemide 前若發現血鉀偏低，通常會直接拒絕給藥並聯絡醫師。
