## 題目

護理師教導個案隔天早上大腸鏡前使用polyethylene glycol電解質液。哪一句話表示教學有效？

## 選項

1. 不需要冷藏。
2. 30分鐘內喝完整瓶溶液。
3. 加入含紅色染料的果汁改善味道。
4. 以240 mL為一份，每10-15分鐘喝一次，分次服用（前一晚一半，檢查前4-6小時一半）；預期會頻繁水樣便。 **✔ 正確答案**

**正確答案: 4**

## 解析

正確 (2)：PEG電解質液最好採分次劑量，前一晚喝一半，檢查前4-6小時喝另一半，每10-15分鐘喝240 mL。效果優於單次服用。冷藏可改善口感，但不可用紅/紫色染料，因內視鏡下可能像血液。(1) 可能噁心/誤吸。(3) 冷藏有幫助。(4) 紅色染料會干擾判讀。

## 深入解析

記憶提示 PEG大腸準備 =「分次、可冷、不要紅」。前一天停固體食物改透明液體；目標為清澈排出液。

## 臨床情境

情境 52歲男性準備隔天上午篩檢大腸鏡；處方PEG 4 L分次服用。正在接受門診衛教。

## 重要概念

- **PEG大腸鏡前處置** — 滲透性大腸鏡前準備；偏好分次劑量。
- **分次劑量方案** — 前一晚半量加檢查前4-6小時半量，可改善視野。
- **腸道準備清晰度** — 目標為黃色/清澈排出液；避免紅/紫色液體。
