## 題目

護理師教導一名因缺鐵性貧血新開立硫酸亞鐵325 mg每日口服的個案。哪一組指導最適當？

## 選項

1. 空腹或與維生素 C（柳橙汁）一起服用；黑便屬預期現象；與鈣、制酸劑和四環黴素至少間隔 2 小時 **✔ 正確答案**
2. 與高纖麩皮穀片一起服用
3. 與制酸劑混合以改善吸收
4. 與牛奶一起服用以舒緩胃部

**正確答案: 1**

## 解析

正確（2）：鐵在空腹加維生素C時吸收較好。深色/黑色糞便是預期且無害的。需與鈣、乳製品、制酸劑、四環黴素、fluoroquinolones、levothyroxine間隔至少2小時。（1、3、4）會降低吸收。

## 深入解析

記憶提示 鐵劑＝空腹＋維生素C＋黑便。液體鐵會染牙，使用吸管；便祕常見，增加水分和纖維。

## 臨床情境

情境 28歲女性缺鐵性貧血，開始使用硫酸亞鐵 325 mg PO daily。門診衛教。

## 重要概念

- **硫酸亞鐵** — 口服鐵鹽；維生素C可促進吸收。
- **鐵與藥物結合** — 鈣、制酸劑、四環黴素、levothyroxine會降低鐵吸收。
- **鐵劑補充** — 治療缺鐵性貧血；網狀紅血球約1週上升，Hgb約2-4週上升；Hgb正常後仍持續3-6個月。
