An oncology patient has begun to experience skin reactions to radiation therapy, prompting the nurse to make the diagnosis Impaired Skin Integrity: erythematous reaction to radiation therapy. What intervention best addresses this nursing diagnosis?

Choice A reason: Applying a heating pad is contraindicated for radiation-induced dermatitis. Thermal stress, whether from heat or extreme cold, can further damage the already compromised epidermal and dermal layers, exacerbating the inflammatory response and increasing the risk of desquamation or secondary infection in the irradiated field. Choice B reason: Massaging the area is harmful because radiation therapy causes structural changes in the microvasculature and skin layers. Physical friction or pressure can lead to mechanical trauma, potentially causing the skin to break down or blister, which compromises the primary barrier against opportunistic pathogens and delays tissue healing. Choice C reason: Hydrocortisone cream should not be applied PRN without specific medical orders, as some topical agents contain metals or chemicals that can interfere with further radiation treatments. Additionally, long-term or inappropriate use of corticosteroids can cause skin thinning, further impairing the integrity of the treated area. Choice D reason: Protecting the skin from mechanical irritation is the priority. Rubbing, scratching, or wearing tight clothing can cause friction that leads to wet desquamation. Maintaining skin integrity involves keeping the area clean, dry, and free from any physical trauma to allow the epithelial cells to regenerate.
