護理師照護一位新接受結腸造口術的病人，下列哪項指導對預防造口周圍皮膚破損至關重要？
A nurse is caring for a client with a new colostomy. Which instruction is crucial for preventing skin breakdown around the stoma?
- AChange the ostomy appliance only once a week每週僅更換一次造口裝置
- BWash the skin around the stoma with harsh soap使用刺激性肥皂清洗造口周圍皮膚
- CEnsure the ostomy appliance fits snugly✓ 正解確保造口裝置緊密貼合
- DApply a thick layer of petroleum jelly around the stoma在造口周圍塗抹厚層凡士林
結腸造口（colostomy）周圍的皮膚護理是預防造口併發症的關鍵。造口排泄物含有消化酵素，若接觸皮膚會造成嚴重的化學性皮膚炎。因此，造口袋貼片（wafer）的開口大小必須與造口吻合（通常建議大於造口 1/8 吋），確保密封良好以防滲漏。適當的皮膚保護與正確的黏貼技術是維持造口周圍皮膚完整性的核心。
Care of the peristomal skin is the key to preventing complications of a colostomy. Stoma effluent contains digestive enzymes, and contact with the skin can cause severe chemical dermatitis. Therefore, the opening of the ostomy wafer must fit the stoma (typically recommended to be 1/8 inch larger than the stoma) to ensure a good seal and prevent leakage. Appropriate skin protection and correct application technique are central to maintaining peristomal skin integrity.
