## 題目

一位 anorexia nervosa 個案因頭暈、心率 44 次/分、血鉀 2.8 mEq/L 入院。哪項問題是優先考量？

## 選項

1. 選擇偏好的餐盤
2. 立即鼓勵團體娛樂活動
3. 討論長期職涯目標
4. 因電解質不平衡導致心律不整的風險 **✔ 正確答案**

**正確答案: 4**

## 解析

Anorexia nervosa 中的嚴重心搏過緩和低血鉀，會造成立即的心律不整風險。生理穩定是優先於長期心理社會目標的考量。營養計畫很重要，但必須在醫療安全監測下進行。

## 深入解析

臨床判斷
當生命徵象和電解質危險時，飲食障礙照護始於醫療穩定。

記憶提示
低血鉀加上心搏過緩：保護心臟。

## 臨床情境

臨床實務指引
Anorexia nervosa 住院重點在於心臟監測、電解質、營養重建、再餵食風險和精神科照護。

注意
再餵食必須監測，因為電解質轉移可能很危險。

## 重要概念

- **Anorexia Nervosa** — 一種涉及限制進食、體重過低，以及害怕體重增加或身體意象障礙的飲食失調。
- **心搏過緩** — 心跳速率比預期慢。
- **電解質失衡** — 礦物質（如鉀）濃度異常，影響器官功能。
