- AAdminister the medication via rapid IV push透過快速靜脈推注給藥
- BInfuse the medication through a peripheral line only僅通過周邊靜脈通路給藥
- CDilute the medication properly and use an infusion pump✓ 正解適當稀釋藥物並使用輸液幫浦

氯化鉀（Potassium chloride）為高警訊藥物（High-alert medication）。絕對不可靜脈直接推注（IV Push），否則會導致致命性心律不整甚至心跳停止。給藥時必須確保藥物經過適當稀釋並使用輸液幫浦定量給藥，以確保給藥速度的穩定。護理師需確認給藥濃度與速度，這是給藥前的絕對安全原則。
Potassium chloride is a high-alert medication. It must never be given by direct IV push, as this can cause fatal dysrhythmias or cardiac arrest. When administering, the nurse must ensure that the drug is appropriately diluted and delivered at a controlled rate using an infusion pump to maintain a steady infusion rate. Verification of the medication concentration and rate is an absolute pre-administration safety principle.
