護理師照顧一位薦骨處有第二級壓瘡的病人，下列哪項處置最合適？
A nurse is caring for a client with a Stage 2 pressure ulcer on the sacrum. Which action by the nurse is most appropriate?
- AUse a donut-shaped cushion for pressure relief使用甜甜圈形坐墊以減輕壓力
- BApply a hydrocolloid dressing to the site✓ 正解在患處塗敷親水性敷料
- CMassage the reddened area to improve circulation按摩發紅區域以促進血液循環
- DLeave the wound open to air for faster drying讓傷口開放通風以加速乾燥
第二級壓瘡涉及表皮與真皮層部分損失，親水性敷料（hydrocolloid）能創造濕潤環境以加速上皮修復並減少摩擦。按摩紅腫處會破壞受損組織；壓瘡護理需避免「開放乾燥」（易結痂延緩癒合）；甜甜圈墊會造成局部充血與組織缺血，應嚴格禁止。
A Stage 2 pressure injury involves partial-thickness loss of the epidermis and dermis. A hydrocolloid dressing creates a moist wound environment that accelerates epithelial repair and reduces friction. Massaging reddened areas can damage already injured tissue; pressure-injury care should avoid leaving wounds open and dry (which promotes scabbing and delays healing); and donut-shaped cushions cause localized congestion and tissue ischemia and are strictly prohibited.
美國機構極為嚴格管制甜甜圈墊的使用；台灣部分基層機構仍有使用習慣，需更新護理標準。
