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. “Use an indoor tanning bed instead of outside.”: Indoor tanning exposes the skin to concentrated ultraviolet radiation, which significantly increases the risk of developing skin cancer, including melanoma. It is not a safe alternative to outdoor sun exposure. B. “Plan to spend time tanning between 10 am and 2 pm.”: This time frame represents peak UV radiation hours, and sun exposure should be minimized during this period to reduce the risk of skin damage and cancer. C. “Apply sunscreen before and after swimming.”: Sunscreen should be applied 15–30 minutes before sun exposure and reapplied after swimming or sweating. Water can wash off sunblock, so reapplication helps maintain effective protection against UV rays. D. “Use sunblock with an SPF of 10 when I am outdoors.”: An SPF of 10 provides minimal protection and is inadequate for preventing skin damage. A minimum SPF of 30 is recommended for effective protection against both UVA and UVB radiation.
