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?

Choice A reason: Patting the area dry after showering is appropriate because it avoids friction and trauma to the irradiated skin. Rubbing can cause irritation, breakdown, or worsen radiation dermatitis. This action demonstrates correct teaching. Choice B reason: Washing the radiation site with antibacterial soap is incorrect. Antibacterial soaps are harsh, drying, and can irritate the skin, worsening radiation-induced damage. Clients should use mild, fragrance-free soap and lukewarm water. This action indicates a need for further teaching. Choice C reason: Wearing clothing to cover the radiation site is appropriate. It protects the skin from sun exposure, trauma, and environmental irritants. Covering the site reduces the risk of complications and supports healing. Choice D reason: Applying prescribed lotions is correct. Radiation therapy often causes dryness and irritation, and prescribed lotions help maintain skin integrity. Using only approved topical agents ensures safety and effectiveness.
