護理師指導病人預防壓瘡，何者正確？
A nurse is teaching a client about the prevention of pressure ulcers. Which instruction is accurate?
- AReposition every 2 hours while in bed✓ 正解在床上時每 2 小時重新定位
- BUse a donut-style cushion to relieve pressure使用甜甜圈型軟墊以減輕壓力
- CMassage the bony prominences frequently經常按摩骨突處
- DKeep the skin moist with frequent bathing通過頻繁洗澡保持皮膚濕潤

預防壓瘡（Pressure ulcer）的核心在於「減壓（Pressure redistribution）」。長期臥床的病人應每 2 小時翻身一次，以維持微血管血流灌注。按摩骨突處會導致組織微血管破裂，反而增加壓瘡風險。此外，甜甜圈軟墊會導致局部壓力集中，應避免使用。保持皮膚清潔但不過度乾燥是正確的皮膚護理方向。
Regular repositioning every two hours is essential to redistribute pressure and maintain microvascular blood flow, thereby preventing tissue ischemia. Massaging bony prominences can damage capillaries, donut cushions cause venous congestion, and excessive bathing strips protective skin oils.
