護理師準備為病人靜脈輸注氯化鉀。下列哪項護理措施對病人安全至關重要？
A nurse is preparing to administer IV potassium chloride to a client. Which nursing action is essential for patient safety?
- AInfuse the medication through a peripheral line only僅透過周邊靜脈輸注該藥物
- BAdminister the medication via IV push經靜脈推注給藥
- CCheck the client's blood glucose level檢查病人的血糖水平
- DVerify the concentration and infusion rate✓ 正解確認濃度與輸注速率

氯化鉀（KCl）屬於高警訊藥物（high-alert medication）。由於鉀離子直接影響心肌細胞電位，若輸注速度過快或濃度過高，極易引發心室顫動（ventricular fibrillation）等致命性心律不整。護理師必須嚴格遵守給藥濃度要求，並使用幫浦（infusion pump）精確控制滴速。
Potassium chloride (KCl) is a high-alert medication. Because potassium directly affects myocardial cell electrical activity, excessively rapid infusion or excessive concentration can readily induce lethal arrhythmias such as ventricular fibrillation. The nurse must strictly adhere to dose concentration requirements and use an infusion pump for precise rate control.
