## 題目

一位患有雷諾現象的個案在接觸寒冷後出現手指蒼白、麻木。護理師應建議採取下列哪項措施？

## 選項

1. 將麻木的手指直接放在設定為高溫的電熱墊上
2. 用力按摩麻木的手指，直到恢復正常顏色和感覺
3. 移至室內，用舒適的溫水逐漸溫暖雙手 **✔ 正確答案**
4. 在寒冷中保持雙手不動，直到感覺自行恢復，無需加溫

**正確答案: 3**

## 解析

雷諾現象發作時，應離開寒冷環境，並逐漸溫暖受影響的部位。舒適的溫水可促進循環，同時避免對感覺減退的手指造成燙傷或組織損傷。

## 深入解析

快速解答
離開寒冷環境，用舒適的溫水逐漸溫暖麻木的手指。

為什麼這是正確的
寒冷會引發血管痙攣，暫時減少手指血流。溫和的回暖與放鬆有助於血管重新擴張，而強烈的直接加熱或用力搓揉可能傷害保護性感覺減退的皮膚。

簡單比喻或心智圖像
逐漸回暖就像慢慢重新打開一個狹窄的水龍頭，而不是用力加壓。這個比喻說明了溫和恢復血流的方式，但無法排除其他血管性病因或組織損傷。

記憶掛鉤
雷諾現象發作：離開寒冷、放鬆、逐漸回暖。

NCLEX 決策規則
對於寒冷引起的血管痙攣，應移除誘因並安全地恢復溫暖。避免直接高溫、用力摩擦、尼古丁和長時間暴露於寒冷；若出現持續疼痛、潰瘍或顏色變化，應立即處理。

為什麼其他選項是錯的
高溫電熱墊可能燙傷麻木的皮膚。用力按摩可能傷害缺血或麻木的組織，而留在寒冷中會延長血管痙攣，而非恢復循環。參考文獻
