護理師準備為低血鉀病人靜脈輸注氯化鉀，下列哪項措施對確保安全性至關重要？
A nurse is preparing to administer potassium chloride IV to a client with hypokalemia. Which action is essential to ensure safety?
- AEnsure the client has an empty bladder before administration確保病人在給藥前排空膀胱
- BMonitor for hypertension during the infusion在輸注期間監測高血壓
- CVerify the concentration and infusion rate via a pump✓ 正解透過輸注幫浦確認濃度與輸注速率
- DAdminister the medication via an IV push經靜脈推注給藥
氯化鉀（Potassium Chloride）具有極高的心臟毒性，絕對禁止靜脈直接推注（IV Push），否則會導致致命性心律不整與心跳停止。給藥必須經過精確的稀釋（通常稀釋至 10-20 mEq/100 mL），並透過輸液幫浦（IV pump）嚴格控制輸注速率（通常不超過 10-20 mEq/hr）。護理師在給藥前必須仔細核對濃度與速率，以確保病人安全。
Potassium chloride has significant cardiac toxicity, and direct IV push is strictly contraindicated, as it can cause lethal arrhythmias and cardiac arrest. The medication must be carefully diluted (typically to 10-20 mEq/100 mL) and administered through an IV pump with strict control of the infusion rate (typically not exceeding 10-20 mEq/hr). Before administration, the nurse must verify the concentration and the infusion rate to ensure client safety.
