病人因急性肺水腫被處方靜脈注射 furosemide。在給藥前，護理師最需要評估下列哪項數據？
A client is prescribed intravenous furosemide for acute pulmonary edema. Which assessment finding is most important for the nurse to evaluate before administration?
- ASerum potassium level✓ 正解血清鉀濃度
- BCapillary refill time微血管回充時間
- CPeripheral pulse strength周邊脈搏強度
- DBlood pressure血壓
Furosemide 為環利尿劑，會導致鉀離子經腎臟大量排出，若病人已有低血鉀（Hypokalemia），給藥將誘發致命性心律不整。雖然血壓監測也很重要，但對環利尿劑而言，電解質失衡帶來的急性致命風險更高。護理師必須確認鉀離子濃度在安全範圍內才可執行醫囑。
Furosemide is a loop diuretic that promotes significant renal excretion of potassium, making serum potassium levels the most critical assessment prior to administration. Administering furosemide to a client with existing hypokalemia can precipitate life-threatening cardiac arrhythmias. Although blood pressure monitoring is important, preventing electrolyte-induced cardiac toxicity takes precedence in this context.
台美臨床皆高度重視給藥前電解質確認，但台灣護理系統常有自動提示機制，美國護理師則更強調獨立評估病歷數據。
