A nurse is teaching a client about skin cancer prevention. Which of the following statements by the client indicates an understanding of the teaching?

A. "I will plan to spend time tanning between 10 a.m. and 2 p.m." UV radiation from the sun is strongest between 10 a.m. and 4 p.m., and sun exposure during this time significantly increases the risk of skin cancer. Outdoor activity should be minimized during peak hours. B. "I will use an indoor tanning bed instead of going outside." Indoor tanning beds expose users to intense UV radiation, which also increases the risk of skin cancer. They are not a safer alternative to natural sunlight and should be avoided. C. "I will use sunblock with an SPF of 10 when I am outdoors." SPF 10 provides minimal protection and is not adequate for skin cancer prevention. The recommended SPF is 30 or higher, applied generously and re-applied regularly. D. "I will apply sunscreen before and after swimming." Sunscreen should be applied 15 to 30 minutes before sun exposure and re-applied every 2 hours, especially after swimming or sweating. This statement shows an understanding of proper sun protection practices.
