一位慢性腎臟病（CKD）病人血鉀濃度為 6.5 mEq/L。護理師的優先護理措施為何？
A client with chronic kidney disease (CKD) has a serum potassium level of 6.5 mEq/L. What is the priority nursing intervention?
- APlace the client on a cardiac monitor✓ 正解將病人安置於心臟監護儀上
- BInstruct the client to avoid bananas指示病人避免食用香蕉
- CRequest a daily potassium level要求每日檢測鉀離子濃度
- DAdminister a dose of oral sodium polystyrene sulfonate給予口服聚苯乙烯磺酸鈉劑量
高血鉀最致命的併發症是致命性心律不整（如心室顫動或心搏停止）。血鉀 6.5 mEq/L 已達危險程度，護理師應先以心電圖監測心臟狀態，以便及時處理心律變化。飲食指導與降鉀藥物雖重要，但屬於穩定病情後的處置，心臟監測才是保障生命的優先考量。
The most lethal complication of hyperkalemia is life-threatening arrhythmias such as ventricular fibrillation and cardiac arrest. A serum potassium level of 6.5 mEq/L is dangerously high, so the nurse should first place the client on a cardiac monitor to enable prompt detection and management of arrhythmias. Dietary teaching and potassium-lowering medications are important, but these are interventions used after the client is stabilized; cardiac monitoring is the priority because it protects life.
美國護理師在發現高血鉀時通常能啟動緊急通知流程；台灣護理師亦同，但給予心電圖監測設備的臨床彈性可能受限於儀器配置。
