氯化鉀（KCl）是高警訊藥物（High-alert medication）。靜脈輸注鉀離子若速度過快或濃度過高，會直接導致嚴重的心律不整，甚至引發心臟驟停。因此，護理師必須嚴格核對輸注濃度與速度，並確保使用輸液泵（Infusion pump）精確控制。絕對禁止以靜脈推注（IV push）方式給藥，這是絕對的醫療禁忌。
Potassium chloride (KCl) is a high-alert medication. Rapid IV infusion or excessive concentration of potassium directly causes severe arrhythmias and even cardiac arrest. Therefore, the nurse must strictly verify infusion concentration and rate, and ensure precise control with an infusion pump. IV push administration is absolutely contraindicated, representing a definitive medical prohibition.
