護理師在社區進行皮膚癌初級預防宣導，參與者說出哪句話代表理解了教學內容？
A nurse is teaching a community group about primary prevention of skin cancer. Which statement by a participant indicates an understanding of the instruction?
- AUsing a tanning bed is safer than direct sun exposure使用美黑床比直接暴露於陽光下更安全
- BDark-skinned individuals do not need to use sunscreen深色皮膚的人不需要使用防曬乳
- CI should wear a hat and sunglasses only when I am at the beach我只在海灘時才需要戴帽子和太陽眼鏡
- DApplying sunscreen with an SPF of at least 30 is recommended✓ 正解建議使用至少 SPF 30 的防曬乳
皮膚癌的初級預防重點在於避免紫外線（UV）傷害。SPF 30 以上的防曬乳能阻擋約 97% 的 UVB，是保護皮膚的基礎。C 選項錯誤，紫外線無所不在，不僅限於海邊；A 選項是錯誤觀念，室內曬黑機產生的紫外線同樣會導致 DNA 損傷；B 選項錯誤，雖然深色皮膚的人黑色素較多，具有天然防護力，但仍可能罹患皮膚癌。正確的衛教應包含：避免在上午 10 點至下午 4 點曝曬、使用廣譜防曬、穿著防護衣物，並強調無論膚色為何都需要防曬。這題評估了病人對於防曬產品選擇及行為模式的認知，是健康維護的重要環節。
Primary prevention of skin cancer focuses on avoiding ultraviolet (UV) damage. Sunscreen with an SPF of at least 30 blocks about 97% of UVB rays and is the basic level of skin protection. Option C is incorrect because UV radiation is ubiquitous, not limited to the beach. Option A is incorrect because UV radiation from indoor tanning beds also damages DNA. Option B is incorrect because, although darker-skinned individuals have more melanin and natural protection, they can still develop skin cancer. Correct teaching should include: avoid sun exposure from 10 AM to 4 PM, use broad-spectrum sunscreen, wear protective clothing, and emphasize that everyone needs sun protection regardless of skin color. This item assesses the client's knowledge of sunscreen product selection and behavior, an important component of health maintenance.
美國皮膚科醫學會（AAD）推廣防曬文化已久，防曬品使用極為普遍；台灣民眾對於防曬多從『美白』角度出發，較少將其與預防皮膚癌的『健康維護』建立直接的醫療認知連結。
