## 題目

一位患有厭食症的個案入院進行醫療穩定。哪項發現需要立即追蹤？

## 選項

1. 手肘皮膚乾燥。
2. 個案表示：「我覺得我很胖。」
3. 鉀離子 2.8 mEq/L 且伴隨頭暈。 **✔ 正確答案**
4. 手臂上長出胎毛。

**正確答案: 3**

## 解析

嚴重的低血鉀可能導致危及生命的心律不整，尤其伴隨頭暈或虛弱時，需要立即追蹤。身體心像困擾、皮膚乾燥和胎毛是重要的發現，但並非最緊急的生理風險。

## 深入解析

臨床判斷
利用個案線索、時機、檢驗數據和安全風險，選擇最符合飲食疾患低血鉀風險的回應。

記憶提示
將最強的線索群與最安全的護理判斷配對。

KR vs US
NCLEX 考題獎勵基於線索的優先思考，而非孤立的回憶。

## 臨床情境

臨床實務指引
對於飲食疾患低血鉀風險，請將完整的線索模式與個案當前的穩定性、醫囑數據和預期的護理範圍進行比較。

注意事項
當完整情境改變了優先順序或安全性時，不要僅根據單一線索選擇行動。

## 重要概念

- **厭食症** — 一種涉及限制進食、體重過輕和身體心像扭曲的飲食疾患。
- **低血鉀** — 血清鉀離子過低，可能導致心律不整和肌肉無力。
- **胎毛** — 嚴重營養不良時可能出現的細小體毛。
