高血鉀（Hyperkalemia）濃度達 6.2 mEq/L 屬於臨床危急值，最直接的威脅是心律不整（如心室顫動或心搏停止）。護理師必須優先進行心電圖監測（Cardiac Monitoring），以隨時掌握心臟傳導狀態，這是 ABC 原則（Airway, Breathing, Circulation）中 Circulation 的重要環節。
A serum potassium level of 6.2 mEq/L indicates hyperkalemia, which poses an immediate risk for life-threatening cardiac dysrhythmias. The nurse must prioritize placing the client on a cardiac monitor to continuously assess heart rhythm and detect any conduction abnormalities early.
