護理師照顧一位厭食症病人，哪些發現會讓護理師懷疑病人可能有電解質不平衡？（選所有適合的）
A nurse is caring for a client with anorexia nervosa. Which findings would lead the nurse to suspect potential electrolyte imbalances? (Select all that apply.)
- ACalluses on the dorsum of the hand✓ 正解手背出現結痂
- BHypotension and bradycardia低血壓和心搏過緩
- CIrregular heartbeat✓ 正解心律不整
- DPeripheral edema✓ 正解周邊水腫
- ELanugo growth on the face臉部出現細軟毛（Lanugo）
— Explanation · 中文詳解 —
厭食症與催吐行為常導致電解質紊亂。手背結痂（Russell's sign）暗示長期催吐，造成鉀流失引發心律不整（Irregular heartbeat）。低蛋白血症與過度依賴利尿劑則會引起周邊水腫（Peripheral edema）。B 與 E 是營養不良的生理指標，但非直接對應電解質紊亂的證據。
Calluses on the dorsum of the hand (Russell’s sign) indicate repeated self-induced vomiting, which leads to potassium loss and subsequent irregular heartbeats. Peripheral edema may also signal electrolyte and protein imbalances associated with purging behaviors. While hypotension and lanugo reflect starvation, they are not direct indicators of electrolyte disturbances.
✦ 台美臨床差異
美國有專門的飲食障礙治療中心；台灣多收治於一般精神科病房，護理重點更強調監測生命徵象與體重變化。
