護理師準備對低血鉀病人執行靜脈輸注氯化鉀，下列哪項措施對病人安全至關重要？
A nurse is preparing to administer IV potassium chloride to a client with hypokalemia. Which action is essential for patient safety?
- AAdminister potassium via IV push經靜脈推注給藥鉀
- BFlush the line with dextrose 5% in water以5%葡萄糖溶液沖洗管路
- CVerify the concentration and infusion rate via pump✓ 正解經輸液幫浦確認濃度與輸注速率
- DPerform the infusion in a peripheral vein only僅於周邊靜脈執行輸注

氯化鉀（KCl）是高警訊藥物（High-Alert Medication）。靜脈輸注時若濃度過高或速度過快，會導致嚴重心律不整甚至心跳停止。護理師必須使用輸液幫浦（Infusion Pump）嚴格控制速率，並確認濃度比例（通常周邊靜脈不得超過 10mEq/hr）。絕對不可靜脈推注（IV Push），否則會直接導致心臟驟停。
Potassium chloride (KCl) is a high-alert medication. When given intravenously, an excessively high concentration or rapid infusion rate can cause severe dysrhythmias or even cardiac arrest. The nurse must use an infusion pump to strictly control the rate and verify the concentration (typically, a peripheral vein should not exceed 10 mEq/hr). IV push administration is absolutely prohibited, as it leads directly to cardiac arrest.
