為病人洗澡時，為了維持醫學無菌原則，護理師應最後清潔身體的哪個部位？
When bathing a client, which part of the body should the nurse wash last to maintain medical asepsis?
- AThe perineal area✓ 正解會陰部
- BThe arms and chest手臂與胸部
- CThe face臉部
- DThe legs腿部
在執行身體清潔（Bed bath）時，護理的核心原則是「由乾淨到髒」（Clean to dirty），以防止微生物從污染區域轉移至乾淨區域。會陰部（Perineal area）因接近腸道與泌尿道開口，帶有大量細菌，若過早清潔會陰部，隨後擦拭其他部位時，會增加交叉感染（Cross-contamination）的風險。因此，清潔順序應為由臉部、上肢、軀幹、下肢，最後才是會陰部。
When performing a bed bath, the core nursing principle is "clean to dirty," to prevent microorganisms from being transferred from contaminated to clean areas. The perineal area, because it is adjacent to the gastrointestinal and urinary tract openings, harbors large numbers of bacteria; cleaning it too early and then wiping other areas increases the risk of cross-contamination. Therefore, the cleansing sequence should proceed from the face, upper extremities, trunk, and lower extremities, with the perineal area cleaned last.
