病人正準備接受 20 mEq 氯化鉀加入 100 mL 生理食鹽水之靜脈輸注。在開始輸注前，護理師的首要行動為何？
A client is receiving an intravenous infusion of potassium chloride 20 mEq in 100 mL of 0.9% Normal Saline. What is the priority nursing action before initiating the infusion?
- AAssess the client's current urine output✓ 正解評估客戶目前的尿量
- BEnsure the infusion is on an electronic pump確保輸注使用電子幫浦
- CVerify the client's serum potassium level核實客戶的血清鉀濃度
- DAssess the peripheral IV site for patency評估周邊靜脈導管的通暢性
給予鉀離子前，確保腎臟功能正常是安全性關鍵，因為高血鉀若無法由尿液排出易導致心律不整。雖然 B 也很重要，但若無尿液輸出，給鉀是禁忌，優先度最高。C 是給藥安全手段，D 是基礎護理步驟，但評估腎功能排泄能力是此給藥行為的生理安全基石。
Before administering potassium, ensuring adequate renal function is the key safety consideration, because hyperkalemia that cannot be excreted in the urine can readily lead to cardiac dysrhythmias. Although option C is also important, administering potassium in the absence of urine output is contraindicated, making this the highest priority. Option B is a medication safety step and option D is a basic nursing action, but assessing renal excretory function is the physiological safety foundation of this administration.
台美皆嚴格要求鉀離子輸注使用幫浦，台灣臨床更強調醫囑核對與給藥前評估尿量。
