- AExcessive preoccupation with calorie counting過度專注於計算卡路里
- BSerum potassium level of 2.8 mEq/L✓ 正解血清鉀濃度 2.8 mEq/L
- CBody mass index of 17.5 kg/m^2身體質量指數 17.5 kg/m^2

厭食症個案常伴隨電解質失衡，其中低血鉀（< 3.5 mEq/L）可能導致致命性心律不整，為最危急的生理徵象。月經失調（閉經）與體重過輕是厭食症的長期診斷特徵，而過度計算卡路里則是典型的認知障礙，雖需處理但皆不如低血鉀造成的急性心臟危機迫切。
A serum potassium level of 2.8 mEq/L indicates severe hypokalemia, which poses an immediate risk for life-threatening cardiac arrhythmias in clients with anorexia nervosa. While low BMI, amenorrhea, and calorie preoccupation are significant findings, electrolyte imbalances affecting cardiac stability require the most urgent nursing intervention.
✦ 台美臨床差異
台美護理師皆須嚴密監測厭食症個案電解質，美國對心理治療的跨團隊合作機制較為成熟。
