## 題目

護理師準備給予IV鐵葡聚糖。依FDA黑框警示，哪一項準備最符合安全作法？

## 選項

1. 不給試驗劑量，直接給予全量
2. 先給予小劑量試驗劑量，並在床旁備妥過敏性休克急救物品（epinephrine、diphenhydramine、O2），監測 30-60 分鐘 **✔ 正確答案**
3. 在30秒內快速靜脈推注
4. 與KCl在同一條管路混合

**正確答案: 2**

## 解析

正確（2）：鐵葡聚糖有FDA過敏性休克黑框警示。必須先給試驗劑量，並觀察30-60分鐘，床旁備妥急救套組。較新的製劑如iron sucrose、ferric carboxymaltose、ferumoxytol風險較低，但仍需監測。（1、3、4）危險。

## 深入解析

記憶提示 IV鐵葡聚糖要想到反應危險，試驗劑量必須做。較新製劑風險較低，但仍需備妥epinephrine並觀察。

## 臨床情境

情境 52歲女性嚴重缺鐵性貧血，口服鐵無效；醫囑iron dextran IV。輸注前準備。

## 重要概念

- **靜脈鐵劑** — 口服鐵失敗或吸收不良時使用，如CKD、IBD、腸胃手術後。
- **鐵葡聚糖過敏性休克** — 有FDA黑框警示；需試驗劑量並觀察30-60分鐘。
- **較新的IV鐵製劑** — 包括iron sucrose、ferric carboxymaltose、ferumoxytol；過敏性休克風險低於鐵葡聚糖。
