護理師準備為低血鉀病人靜脈輸注氯化鉀，下列哪些措施是必要執行？（選所有適合的）
A nurse is preparing to administer potassium chloride intravenously to a client with hypokalemia. Which of the following actions is essential for the nurse to perform? (Select all that apply.)
- AVerify the medication is diluted according to facility protocol✓ 正解確認藥物已依機構規範稀釋
- BAdminister the medication via a dedicated IV line透過專用靜脈通路給藥
- CAssess the patency of the IV site before infusion✓ 正解輸注前評估靜脈通路的暢通性
- DAdminister the infusion via an electronic infusion pump✓ 正解使用電子輸注幫浦進行輸注
- ECheck that the infusion rate does not exceed 10 mEq/hr in a peripheral line✓ 正解確認周邊靜脈輸注速率不超過 10 mEq/hr
氯化鉀具有極強的組織刺激性，濃度過高或滴速過快易導致靜脈炎或心律不整。給藥前務必確認管路暢通，絕不可透過未稀釋的靜脈推注（IV push）。必須使用輸液幫浦確保滴速精確，並嚴格控制 peripheral 靜脈每小時輸注上限。B 選項非必要條件，重點在於給藥安全性而非專用管路。
Potassium chloride is highly irritating to veins. It must never be given by IV push; it must be diluted per protocol, the IV site must be patent (extravasation causes tissue necrosis), and the infusion must be controlled with an infusion pump to prevent fatal arrhythmia. Peripheral lines have rate limits (typically 10 mEq/hr). A dedicated line is preferred but not strictly mandatory when compatible.
台灣醫院對高警訊藥物（如 KCl）的管理極為嚴格，通常需雙人核對；美國亦同，但各州護理執業法規對靜脈給藥範圍稍有不同。
