厭食症雖屬心理疾患，但低血鉀（2.8 mEq/L）可能引發嚴重心律不整，是導致此類病人猝死的主因，屬於生理危急值。選項 A、D、C 均為厭食症常見的長期臨床表徵，重要但非急性生命的威脅，必須優先處理致命的電解質不平衡。
Although anorexia nervosa is a psychiatric disorder, hypokalemia (2.8 mEq/L) can precipitate severe cardiac arrhythmias and is a leading cause of sudden death in these clients, representing a critical physiological value. Options A, D, and C are common long-term clinical features of anorexia nervosa, important but not immediately life-threatening. The life-threatening electrolyte imbalance must be addressed first.
