護理師照護活動受限的病人，預防皮膚破損最重要的護理措施為何？
A nurse is caring for a client with restricted mobility. Which of the following is the most important nursing intervention to prevent skin breakdown?
- AMassaging the bony prominences按摩骨突處
- BApplying powder to high-friction areas在高摩擦區域塗抹滑石粉
- CRepositioning the client every 2 hours✓ 正解每 2 小時為病人翻身
- DEncouraging a high-protein diet鼓勵攝取高蛋白飲食
預防壓力性損傷（Pressure injury）的原則在於減輕持續性壓力對皮膚與皮下組織的缺血性傷害。每兩小時翻身（Repositioning）是臨床公認預防壓瘡最有效的物理介入措施，能有效重建組織血液循環。現行指引已明確指出不應按摩骨突處，因為按摩會造成深層組織受損（Deep tissue injury），加劇損傷風險。營養雖重要，但翻身是護理師能直接控制的最關鍵預防手段。
The principle for preventing pressure injuries is to relieve sustained pressure that causes ischemic injury to the skin and underlying tissue. Repositioning every 2 hours is the most effective physical intervention recognized clinically for preventing pressure ulcers, as it effectively restores tissue blood circulation. Current guidelines clearly state that bony prominences should not be massaged, because massage causes deep tissue injury and worsens damage. Although nutrition is important, repositioning is the most critical preventive measure that the nurse can directly control.
