一位足跟二期壓瘡的病人需要更換敷料。哪種敷料最適合維持傷口濕潤環境？
A client with stage 2 pressure injury on the heel requires a dressing change. Which dressing is most appropriate to maintain a moist environment?
- AWet-to-dry gauze濕對乾紗布
- BAlginate dressing藻酸鹽敷料
- CDry sterile gauze乾燥無菌紗布
- DTransparent film dressing✓ 正解透明薄膜敷料
二期壓瘡（Stage 2 Pressure Injury）涉及表皮與真皮層的部分皮層缺失。此類傷口護理的核心目標是「維持濕潤環境（Moist wound healing）」，這能促進上皮細胞遷移並加速癒合，同時防止傷口乾燥結痂。透明薄膜敷料（Transparent film）具有半透膜特性，能阻隔水分與細菌進入，但允許氣體交換，是處理淺層傷口最理想的選擇。
A stage 2 pressure injury involves partial-thickness loss of the epidermis and dermis. The core goal of wound care is to maintain a moist wound healing environment, which promotes epithelial cell migration and accelerates healing while preventing the wound from drying and forming an eschar. A transparent film dressing has semi-permeable properties; it blocks water and bacteria while allowing gas exchange, making it the ideal choice for superficial wounds.
在美國臨床執業中，Wet-to-dry 敷料已幾乎被淘汰，因為其對傷口癒合具有破壞性。NCLEX 考試中，應始終選擇能維持濕潤環境的現代敷料（如薄膜、水膠體或泡沫敷料）。
