護理師準備給予靜脈注射氯化鉀（KCl），哪項是優先行動？
A nurse is preparing to administer IV potassium chloride. Which action is the priority for the nurse?
- ACheck for peripheral edema檢查周邊水腫
- BAssess the client's blood pressure評估病人血壓
- CVerify the concentration and infusion rate✓ 正解確認濃度與輸注速率
- DCheck the client's serum creatinine level檢查病人血清肌酸酐值
— Explanation · 中文詳解 —
KCl 是高警訊藥物（High-alert medication），給予過快會導致致命性心律不整。護理師給藥前最重要的安全防護是核對濃度與輸注速率（通常需稀釋且不得超過 10 mEq/hr 週邊給藥）。D 選項重要但屬於腎功能評估；B、A 與給藥安全的核心原則（預防心臟驟停）關聯性較弱。
Potassium chloride is a high-alert medication because rapid infusion can cause fatal cardiac arrhythmias. The priority nursing action is to verify the prescribed concentration and infusion rate, ensuring it is diluted and administered slowly (typically no faster than 10 mEq/hour via peripheral line) to prevent cardiac arrest.
✦ 台美臨床差異
美國護理師常需藥師 double-check；台灣護理師依醫囑給藥，強調自行核對輸注速率與過濾器使用。
