哪項評估發現對於 70 歲長者而言，屬於正常的皮膚系統老化變化？
Which assessment finding in a 70-year-old client is considered a normal age-related change in the integumentary system?
- AThinning and dryness of the epidermis✓ 正解表皮變薄與乾燥
- BIncreased subcutaneous fat in the extremities四肢皮下脂肪增加
- CRapid wound healing傷口快速癒合
- DIncreased skin turgor皮膚彈性增加
皮膚系統老化是老年照護的核心概念。隨著年齡增長，表皮細胞更新變慢，表皮層變薄，且皮脂腺與汗腺分泌減少，導致皮膚喪失保水能力，呈現乾燥、脆弱且易受損。正確答案 A 反映了生理性退化。選項 D、C、B 皆與正常老化趨勢相反。臨床上，護理師需特別注意老年病人的皮膚完整性，預防壓力性損傷（Pressure Injury）及撕裂傷。
Aging of the integumentary system is a core concept in geriatric care. With increasing age, epidermal cell turnover slows, the epidermis becomes thinner, and sebaceous and sweat glands produce less secretion, causing the skin to lose moisture and become dry, fragile, and easily injured. The correct answer, A, reflects this physiologic decline. Options D, C, and B all represent changes opposite to those of normal aging. Clinically, the nurse must pay special attention to maintaining skin integrity in older adults to prevent pressure injuries and skin tears.
