低血鉀病人出現下列哪項評估發現時，需要護理師立即關注？

低血鉀（Hypokalemia）會影響神經肌肉傳導。最危險的併發症是呼吸肌無力，導致呼吸淺快（Shallow respirations），進而可能發展為呼吸衰竭。肌肉痙攣、腸音減弱及多尿也是低血鉀表現，但呼吸功能的維護屬於 ABC（Airway, Breathing, Circulation）中的優先事項。

Hypokalemia impairs neuromuscular conduction. The most dangerous complication is respiratory muscle weakness, resulting in shallow respirations and potentially progressing to respiratory failure. Muscle cramps, decreased bowel sounds, and polyuria are also manifestations of hypokalemia, but maintenance of respiratory function is the priority within the ABC (Airway, Breathing, Circulation) framework.
