A Patient Who Is Planning a Vacation to the Beach

A patient who is planning a vacation to the beach asks the nurse about precautions that should be taken to protect the skin while enjoying the sun and water. The nurse's best response is

A) "Sunscreens that contain metals like zinc or titanium provide a physical barrier and are the most effective at blocking ultraviolet rays."
B) "If you use a waterproof sunscreen with an SPF of 15 to the exposed areas of your skin, you won't have to apply it every time you swim."
C) "To avoid getting sunburn, gradually increase the time of sun exposure each day, starting with 30 minutes a day and adding 30 minutes each following day."
D) "Sunscreens with an SPF of 40 to 50 will provide full protection against both types of ultraviolet rays and should be applied before sun exposure."
