A nurse is preparing to administer potassium chloride IV to a client. Which action is the priority for safety?
- AVerify the concentration and dilution of the potassium solution✓ 正解確認氯化鉀溶液的濃度與稀釋比例
- BEnsure the client has not eaten for four hours確保病人已禁食四小時
- CAdminister the medication via IV push to ensure rapid effect透過靜脈推注給藥以確保快速療效
- DCheck the client's blood pressure before infusion在輸注前檢查病人的血壓

氯化鉀（Potassium Chloride, KCl）屬於高警訊藥物（High-alert medication）。靜脈輸注時，因其會對血管產生極大刺激，且過快輸注會直接導致致命性的心律不整（如心室顫動），因此必須確保稀釋濃度正確，並使用輸液幫浦（IV Pump）精確控制速度。絕對禁止以靜脈推注（IV Push）方式給予。
Potassium chloride is a high-alert medication that can cause fatal cardiac arrhythmias if administered too rapidly or undiluted. The priority safety action is to verify the correct concentration and dilution, ensuring it is infused via pump rather than IV push to prevent phlebitis and cardiac toxicity.
