下列何者為皮膚癌的初級預防措施？
Which of the following is a primary prevention measure for skin cancer?
- ABiopsy of suspicious skin lesions對可疑皮膚病變進行切片檢查
- BAvoiding excessive UV exposure✓ 正解避免過度暴露於紫外線下
- CRegular skin cancer screenings定期進行皮膚癌篩檢
- DMonitoring moles for changes監測痣的變化
初級預防（Primary Prevention）的目的是在疾病發生前消除潛在的危險因子，以達到「防患於未然」的效果。皮膚癌的主要致病因子為長期紫外線（UV）曝曬，因此採取防曬措施屬於最前線的預防策略。次級預防（Secondary Prevention）則著重於早期發現與治療，包括篩檢、診斷與監測。在臨床思路中，護理師應釐清預防層級，將重點放在介入致病源，而非在疾病發生後的補救。
The goal of primary prevention is to eliminate potential risk factors before disease develops, thereby preventing the problem at its source. The principal causative factor for skin cancer is long-term ultraviolet (UV) exposure, so sun protection is the frontline preventive strategy. Secondary prevention focuses on early detection and treatment, including screening, diagnosis, and monitoring. Clinically, the nurse should distinguish levels of prevention and focus interventions on the underlying cause rather than remedial actions taken after disease occurs.
