病人獲醫囑給予靜脈注射氯化鉀 20 mEq。護理師在給藥過程中哪項安全行動至關重要？
A client is prescribed intravenous potassium chloride 20 mEq. Which nursing action is essential to ensure safety during administration?
- AEnsure the client has a central venous line確認個案擁有中心靜脈導管
- BAdminister the dose as an IV push bolus以靜脈推注方式給予劑量
- CVerify the concentration and infusion rate via a pump✓ 正解透過幫浦確認濃度與輸注速率
- DDilute the medication in 500 mL of normal saline將藥物稀釋於 500 mL 之生理鹽水中
靜脈輸注鉀離子具極高風險，錯誤投藥可引發心跳停止。必須經由輸液幫浦控制速率，且濃度不可超過 10-20 mEq/100 mL。A 為絕對禁忌（直接致死）；C 非必須，週邊靜脈亦可輸注；D 稀釋量過大會影響給藥時效，通常以 100 mL 為標準。
Intravenous potassium administration carries extreme risk; medication errors can cause cardiac arrest. It must be administered via an infusion pump with controlled rate, and the concentration must not exceed 10-20 mEq/100 mL. Option B is absolutely contraindicated (directly lethal); option A is not required, as a peripheral IV can also be used; option D, an excessively large dilution volume, would affect the timeliness of administration; 100 mL is the standard.
台美均強調鉀離子需經幫浦，但台灣臨床對高濃度鉀離子回報與核對流程更為嚴格。
