## 題目

## 解析

B以大範圍支撐小腿，使足跟得以懸空。

## 深入解析

快速解答
B. B以大範圍支撐小腿，使足跟得以懸空。
為何這是最佳選擇
支撐物必須抬高足跟，同時避免在阿基里斯腱或膝蓋後方造成新的局部壓力點。大範圍的小腿支撐可分散小腿負荷。擺位後應重新檢查實際的足跟懸空情形與對齊狀況。
臨床情境
這些觀察為虛構的教學資料。請應用所述情境；所選特徵本身不能取代完整的床邊評估。
記憶口訣
藉由沿小腿分散腿部重量來抬高足跟。
決策原則
藉由沿小腿分散腿部重量來抬高足跟。
為何其他區域不合適
A承重於膝蓋後方區域。C將壓力集中於阿基里斯腱附近。D直接支撐足跟，違背了減輕足跟壓力的目標。
**資料來源**
- 足跟抬高應沿小腿分散小腿重量，並避免壓迫阿基里斯腱及膕窩區域。

## 重要概念

- **Heel offloading without new focal pressure** — 藉由沿小腿分散腿部重量來抬高足跟。
- **Comparison with context** — C靠近足跟，可能可以抬高它，但會造成肌腱局部壓力，而非分散負荷。
