一位診斷為神經性厭食症的個案，下列哪些臨床發現需護理師優先通知醫師？（選所有適合的）
A client is diagnosed with anorexia nervosa. Which findings would lead the nurse to prioritize an immediate referral to the physician? (Select all that apply.)
- APotassium level of 2.8 mEq/L✓ 正解鉀離子濃度為 2.8 mEq/L
- BAmenorrhea for six months停經六個月
- CHeart rate of 42 beats/min✓ 正解心率为 42 次/分
- DLanugo growth on arms手臂長出細軟毛
- ESerum albumin level of 2.2 g/dL✓ 正解血清白蛋白濃度為 2.2 g/dL
神經性厭食症需關注生理不穩定的生命徵象與實驗室數值。低血鉀（<3.5 mEq/L）易引發心律不整；心搏過緩（<45 bpm）代表心血管失代償；低白蛋白代表嚴重營養不良與體液分布異常。停經與軟毛生長為長期症狀，雖需追蹤但非急性致死威脅。
In anorexia nervosa, the nurse must pay attention to unstable vital signs and laboratory values. Hypokalemia (<3.5 mEq/L) can readily precipitate dysrhythmias; bradycardia (<45 bpm) indicates cardiovascular decompensation; and low albumin reflects severe malnutrition and abnormal fluid distribution. Amenorrhea and lanugo growth are chronic manifestations and warrant follow-up, but they do not represent acute, life-threatening findings.
美國有針對飲食疾患的多專業團隊（MDT）；台灣個案多在精神科門診或身心科病房治療，較少有專屬飲食疾患團隊。
