## 題目

給予靜脈注射藥物時，哪項行動有助於降低中心導管相關血流感染的風險？

## 選項

1. 如果管路仍可沖洗，則無限期使用同一套管路。
2. 在給藥間隔中斷管路連接，讓導管休息。
3. 若會戴手套，則省略手部衛生。
4. 使用前以抗菌劑用力擦拭導管接頭。 **✔ 正確答案**

**正確答案: 4**

## 解析

使用前消毒接頭可降低將微生物帶入中心導管的風險。即使戴手套，手部衛生仍屬必要。不必要的管路中斷連接及無限期使用管路可能增加感染風險。

## 深入解析

臨床判斷
利用個案線索、時機、檢驗數據及安全風險，選擇最符合中心導管接頭消毒的回應。

記憶提示
將最強的線索群組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，而非單獨的記憶。

## 臨床情境

臨床實務指引
針對中心導管接頭消毒，將完整的線索模式與個案當前的穩定性、醫囑數據及預期的護理範圍進行比較。

注意
當完整情境改變優先順序或安全性時，切勿僅根據單一線索選擇行動。

## 重要概念

- **中心導管** — 一種尖端位於中心靜脈的靜脈導管。
- **CLABSI** — 中心導管相關血流感染。
- **接頭消毒** — 使用前清潔導管注射端口。
