## 題目

護理師教導個案使用scopolamine經皮貼片預防暈車/暈船。哪一項指示最重要？

## 選項

1. 剪開貼片以調整劑量
2. 一次貼兩片以增強效果
3. 旅行前1小時貼在腹部
4. 旅行前至少4小時貼在耳後；處理後徹底洗手，避免藥物進入眼睛造成散瞳 **✔ 正確答案**

**正確答案: 4**

## 解析

正確 (2)：Scopolamine貼片應在旅行前至少4小時貼於耳後；脂溶性藥物吸收較慢。處理後要洗手，碰到眼睛會造成瞳孔不等與視力模糊。可維持72小時。(1) 不是貼腹部，而是耳後特定部位。(3) 剪開會破壞控釋。(4) 有過量風險。

## 深入解析

記憶提示 Scopolamine =「耳後、洗手、72小時」。抗膽鹼作用：口乾、嗜睡、視力模糊、尿滯留。

## 臨床情境

情境 28歲女性，為即將到來的郵輪旅行開立scopolamine 1.5 mg經皮貼片。正在接受門診衛教。

## 重要概念

- **Scopolamine經皮貼片** — 預防暈車/暈船的脂溶性抗膽鹼貼片；效果維持72小時。
- **瞳孔不等** — 兩眼瞳孔大小不等；接觸貼片後碰到單眼可造成。
- **抗膽鹼作用** — 口乾、嗜睡、視力模糊、尿滯留；與青光眼/BPH有相同注意事項。
