靜脈給予氯化鉀（KCl）屬於高警訊藥物（High-alert medication）。鉀離子對血管壁有極強的刺激性，若濃度過高或給予速度過快，會導致嚴重的血管疼痛、化學性靜脈炎，甚至誘發致命性的心律不整（Arrhythmia）。因此，給藥前必須嚴格執行「三讀五對」，並確認藥物已根據機構規範完成適當稀釋。
Intravenous potassium chloride is a high-alert medication that can cause severe phlebitis, tissue necrosis, or fatal arrhythmias if administered undiluted or too rapidly. Therefore, it is essential to verify that the medication has been properly diluted according to facility protocols before administration.
