護理師協助長期臥床的長者進行清潔。哪項護理措施最能促進此病人的皮膚完整性？

核心概念：預防長期臥床老年人皮膚完整性受損的照護原則。 為何正確答案對： B. 使用溫和、pH 值平衡的清潔劑並徹底拍乾：皮膚的完整性依賴於其天然的皮脂保護層和適當的水分。溫和、pH 值平衡的清潔劑（pH-balanced cleanser）能溫和地清潔皮膚，避免過度去除皮膚的天然油脂，減少乾燥和刺激。清潔後，使用柔軟的毛巾輕輕拍乾（pat dry thoroughly），避免用力摩擦，特別是骨突部位，這樣可以最大程度地保護皮膚，維持其屏障功能，預防因潮濕、摩擦或過度乾燥引起的損傷。 為何其他選項錯： A. 塗抹厚層嬰兒爽身粉：爽身粉（baby powder），特別是滑石粉基底的，雖然有吸濕作用，但容易結塊，尤其在皮膚皺褶處。結塊的粉末可能刺激皮膚，並為細菌（bacteria）提供生長環境，增加皮膚損傷和感染的風險。此外，過度依賴爽身粉可能掩蓋皮膚變紅的早期跡象。 C. 大力按摩骨突部位：雖然按摩可以刺激血液循環，但對於長期臥床、皮膚脆弱的長者，用力按摩骨突部位（bony prominences，如薦骨、腳跟、髖骨）反而可能對皮下組織造成深層壓力性損傷（pressure injury）或剪力（shear force）傷害。早期發現的紅腫應輕柔處理，避免按摩。 D. 用熱水沐浴以促進周邊血循：熱水（hot water）會過度去除皮膚的天然油脂，導致皮膚乾燥、脫屑，甚至可能造成燙傷。儘管熱水可能暫時擴張血管，但長期使用反而會損害皮膚屏障，不利於皮膚完整性。應使用溫水（lukewarm water）進行清潔。 臨床思路：此題考量的是「基本照護與舒適」（Basic Care & Comfort）領域中，預防壓瘡（pressure ulcer）的關鍵措施。壓瘡的發生與壓力、剪力、摩擦、潮濕、乾燥及營養不良等因素有關。因此，維持皮膚清潔、乾燥、滋潤，並減輕壓力是預防的重點。這題的關鍵在於選擇最能「促進皮膚完整性」的措施，即溫和清潔與輕柔拍乾。

Core concept: principles of care for preventing impaired skin integrity in older adults on prolonged bed rest. Why the correct answer is right: B. Using a mild, pH-balanced cleanser and patting the skin thoroughly dry: skin integrity depends on its natural sebum protective layer and adequate hydration. A mild, pH-balanced cleanser gently cleans the skin while avoiding excessive removal of natural oils, reducing dryness and irritation. After cleansing, using a soft towel to pat the skin dry thoroughly avoids friction, especially over bony prominences. This protects the skin to the greatest extent, maintains its barrier function, and prevents damage caused by moisture, friction, or excessive dryness. Why the other options are wrong: A. Applying a thick layer of baby powder: baby powder, particularly talc-based powder, has absorbent properties but tends to clump, especially in skin folds. Clumped powder may irritate the skin and provide an environment for bacterial growth, increasing the risk of skin damage and infection. In addition, overreliance on powder may mask early signs of skin redness. C. Vigorously massaging over bony prominences: although massage can stimulate circulation, in older adults on prolonged bed rest with fragile skin, vigorous massage over bony prominences (such as the sacrum, heels, and hips) can produce deep pressure injury or shear injury in the underlying tissues. Early redness should be handled gently, and massage should be avoided. D. Bathing in hot water to promote peripheral circulation: hot water excessively strips the skin of natural oils, producing dryness, flaking, and even burns. Although hot water can transiently dilate vessels, long-term use damages the skin barrier and is unfavorable to skin integrity. Lukewarm water should be used for cleansing. Clinical reasoning: this item considers the prevention of pressure ulcers within the Basic Care and Comfort domain. Pressure ulcer development is associated with pressure, shear, friction, moisture, dryness, and inadequate nutrition. Keeping the skin clean, dry, moisturized, and relieved of pressure is therefore the focus of prevention. The key is to choose the measure that best promotes skin integrity, namely gentle cleansing and gentle patting dry.
