護理師準備為低血鉀病人靜脈輸注氯化鉀，給藥前最高優先級的評估發現為何？
A nurse is preparing to administer intravenous potassium chloride to a client with hypokalemia. Which assessment finding is the highest priority for the nurse to verify before starting the infusion?
- AUrine output of at least 30 mL/hr✓ 正解每小時至少 30 mL 的尿量
- BRespiratory rate of 16 breaths/min每分鐘 16 次的呼吸次數
- CPresence of peripheral edema周邊水腫的存在
- DBlood pressure reading血壓讀數
靜脈輸注鉀離子有致死風險，給藥前務必確認腎功能。若病人無尿（anuria）或少尿（oliguria），輸注鉀離子會導致高血鉀危象。尿量 > 30 mL/hr 是判斷腎排泄功能尚存的臨床重要指標，以確保鉀能順利排除，預防急性高血鉀引起的心律不整。
Intravenous potassium administration carries a fatal risk, so renal function must be verified before the infusion. If the client is anuric or oliguric, IV potassium can precipitate a hyperkalemic crisis. Urine output greater than 30 mL/hr is a critical clinical indicator that renal excretory function is preserved, ensuring that potassium can be eliminated and preventing acute hyperkalemia-induced arrhythmias.
美台臨床皆嚴格要求確認尿量方可給予靜脈補鉀，若無法確認尿量，護理師應先主動通知醫師。
