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

Rationale: A. “I will apply sunscreen before and after swimming.” Sunscreen should be applied at least 15–30 minutes before sun exposure and reapplied after swimming or sweating, even if labeled water-resistant, to maintain UV protection. B. “I will use sunblock with an SPF of 10 when I am outdoors.” SPF 10 offers minimal protection and is below the recommended minimum of SPF 30 for effective skin cancer prevention. Higher SPF levels provide greater protection against harmful UV rays. C. “I will use an indoor tanning bed instead of going outside.” Indoor tanning beds emit concentrated UV radiation and are strongly associated with increased risk for skin cancer, including melanoma. They should not be used as a safer alternative to sun exposure. D. “I will plan to spend time tanning between 10 a.m. and 2 p.m.” UV radiation is most intense between 10 a.m. and 2 p.m., making this the highest-risk period for skin damage. Sun exposure during these hours should be minimized or avoided to prevent skin cancer.
