護理師準備為病人靜脈輸注氯化鉀（KCl），哪項行動對於降低併發症風險是必要的？
A nurse is preparing to administer potassium chloride intravenous piggyback to a client. Which action is necessary to reduce the risk of potential complications?
- ARequest the physician to discontinue if the client complains of mild burning若病患抱怨輕微灼熱感，請醫師停止給藥
- BAdminister the medication through a peripheral IV in the hand透過手部周邊靜脈給藥
- CVerify the concentration and infusion rate via an electronic infusion pump✓ 正解透過電子輸注幫浦驗證濃度與輸注速率
- DAdminister the infusion as an IV push以靜脈推注方式給藥
氯化鉀具有極強的血管刺激性，若推注（IV push）會直接導致心律不整甚至心跳停止。必須使用輸注幫浦嚴格控制速率，且濃度須依規定稀釋，避免對血管內膜造成灼傷或壞死。若病患感到疼痛，應考慮中心靜脈導管輸注，而非直接停藥。
Potassium chloride is highly irritating to blood vessels; administered by IV push, it can directly cause dysrhythmias or even cardiac arrest. An infusion pump must be used to strictly control the rate, and the concentration must be diluted according to protocol to prevent burning or necrosis of the vascular intima. If the client experiences pain, central venous catheter infusion should be considered rather than simply discontinuing the medication.
美國高風險藥物雙人核對流程極為嚴謹；台灣亦有相關條例，但基層人力負擔較重時核對壓力較大。
