低鉀血症（Hypokalemia）會導致心肌細胞去極化異常，進而引發致命的心律不整。雖然肌肉無力、腸蠕動減慢與抽筋也是常見症狀，但這些屬於生理功能受損，而心律不整直接威脅生命（Life-threatening），依據 ABC 原則與優先級排序，護理師必須優先處理心血管風險，立即回報醫師並監測心電圖。
Hypokalemia can cause abnormal myocardial depolarization, leading to life-threatening cardiac dysrhythmias. While muscle weakness, leg cramps, and reduced bowel sounds are common symptoms, they are not immediately fatal. According to ABC principles, cardiovascular risks take priority, so the nurse must report irregular heart rhythms immediately.
