護理師準備為病人靜脈輸注氯化鉀。下列哪項行動對於確保病人安全最重要？
A nurse is preparing to administer IV potassium chloride to a client. Which action is the highest priority to ensure client safety?
- AVerify the concentration and infusion rate via an electronic pump✓ 正解透過電子幫浦確認濃度與輸注速率
- BAssess the peripheral site for coolness and edema評估周邊部位是否有冰冷和水腫
- CAdminister the medication via IV bolus push to ensure rapid effect以靜脈推注方式給藥以確保快速效果
- DCheck the client's blood pressure prior to administration在給藥前檢查病人的血壓
— Explanation · 中文詳解 —
氯化鉀（KCl）是高警訊藥物，禁止直接靜脈推注（IV Push）。過快注入會導致嚴重心律不整甚至心搏停止。必須透過電子輸液幫浦（Electronic infusion pump）嚴格控制濃度與速率。檢查輸注部位是否回血雖重要，但確保藥物安全劑量與滴速是預防致命性給藥錯誤的首要條件。
Potassium chloride is a high-alert medication that must never be administered via IV push due to the risk of fatal arrhythmias. The highest priority is to verify the concentration and use an electronic infusion pump to ensure the medication is delivered at a safe, controlled rate.
✦ 台美臨床差異
美台均將 KCl 列為高警訊藥物（High-Alert Medication），需雙人核對（Double-check）給藥。
