The nurse is teaching a client with cancer about skin care for the portal site receiving external beam radiation. Which client action about skin care indicates a need for further teaching?

A. Dries the area with patting motions after taking a shower: Gently patting the skin dry avoids friction and irritation to the radiation site, which is consistent with recommended skin care for clients receiving external beam radiation. This action demonstrates proper understanding of protecting sensitive skin. B. Washes the radiation site with antibacterial soap and water: Using antibacterial soap on the radiation site can be too harsh and may strip natural oils, causing irritation or dryness. Standard recommendations advise using mild, non-irritating soap (such as unscented, gentle cleansers) and lukewarm water. This indicates a need for further teaching because the client may inadvertently exacerbate skin breakdown. C. Wears clothing to cover the radiation site: Protecting the area from friction, sun exposure, and environmental contaminants by wearing loose, soft clothing aligns with best practices in radiation skin care. This behavior reduces irritation and promotes healing. D. Applies prescribed lotions to the radiation site: Applying moisturizers or topical agents prescribed by the healthcare provider helps prevent dryness and irritation. Using only prescribed products avoids interference with the radiation treatment, demonstrating correct client understanding of skin care protocols.
