A nurse is teaching a client who is receiving radiation therapy about skin protection. Which of the following client statements indicates an understanding of the teaching?

Rationale: A. "I will expose the irradiated area of skin to the sun for no more than 30 minutes per day.": Skin that has been irradiated is highly sensitive to sunlight, and any direct exposure can increase the risk of burns and further damage. Clients should avoid sun exposure entirely on affected areas. B. "I will apply my favorite unscented lotion to the irradiated area of skin twice each day.": Applying lotion may be appropriate if recommended by the radiation oncology team, but the client should avoid using any lotion, cream, or ointment not approved for use on irradiated skin, as some products can irritate the area. C. "I will use my hand instead of a washcloth to wash the irradiated area of skin.": Using the hand is the safest method for cleansing irradiated skin, as washcloths can cause friction, irritation, or breakdown. Gentle washing helps protect fragile skin and prevent injury during radiation therapy. D. "I will make sure I have sterile water to wash the irradiated area of skin.": Sterile water is not required for routine skin care of irradiated areas. Mild soap and lukewarm tap water are typically sufficient unless the provider specifies otherwise.
