護理師督導新人準備給予靜脈鉀離子補充，哪項行為需要介入？
A nurse is supervising a newly licensed nurse who is preparing to administer IV potassium chloride. Which action by the new nurse requires intervention?
- AAdministering the medication via IV push✓ 正解經靜脈推注給藥
- BVerifying the client's potassium level核對客戶的血鉀值
- CChecking the IV site for infiltration檢查靜脈穿刺處是否有滲漏
- DChecking the infusion pump rate檢查輸液幫浦的流速
氯化鉀（KCl）是高警訊藥物（High-alert medication）。靜脈注射 KCl 具有極高的風險，若濃度過高或速度過快，會直接影響心肌電傳導，導致致命性心律不整甚至心跳停止。因此，KCl 絕對禁止直接靜脈推注（IV push）。護理師在督導新人時，必須確保其嚴格遵守給藥安全規範，任何違反給藥路徑的操作都必須立即介入停止。
Potassium chloride (KCl) is a high-alert medication. Intravenous KCl carries an extremely high risk: if the concentration is too high or the infusion rate too fast, it will directly affect myocardial electrical conduction and may cause fatal arrhythmias or even cardiac arrest. Therefore, intravenous push administration of KCl is absolutely prohibited. When supervising a novice nurse, the preceptor must ensure strict adherence to medication safety standards, and any deviation from the correct route of administration must be stopped immediately.
