護理師準備對病人靜脈注射 20 mEq 氯化鉀，哪項是護理師的優先行動？
A nurse is preparing to administer potassium chloride 20 mEq IV bolus to a client. What is the nurse's priority action?
- AVerify the patient's serum potassium level確認病人的血清鉀濃度
- BDilute the medication in 100 mL of normal saline將藥物稀釋於 100 mL 生理鹽水中
- CClarify the order with the physician✓ 正解與醫師釐清醫囑
- DCheck the IV site for infiltration檢查靜脈注射部位是否有滲漏
氯化鉀（Potassium chloride）絕對禁止靜脈直接推注（IV Push / Bolus），因為這會導致血鉀瞬間飆升，引發致命性心律不整。給藥必須先經過稀釋，並透過輸液幫浦緩慢滴注。護理師在面對任何不符合安全規範的醫囑時，有責任拒絕執行並與醫師進行釐清（Clarify）。這是護理師作為病人安全守門員的重要角色，不可為了執行醫囑而犧牲病人的安全。
Potassium chloride must never be administered as a direct intravenous push (IV push/bolus), because this causes an instantaneous surge in serum potassium and can precipitate fatal cardiac arrhythmias. The drug must first be diluted and then infused slowly through an infusion pump. When faced with any order that does not meet safety standards, the nurse has the responsibility to refuse to carry it out and to clarify the order with the physician. This reflects the nurse's important role as the gatekeeper of patient safety; patient safety must never be sacrificed simply for the sake of carrying out an order.
