Radiation therapy to the skin can cause dermatitis, so the nursing action that best supports patient comfort and skin integrity is to shield the treated area from irritation. The skin becomes more fragile and prone to redness, itching, cracking, and infection, so avoiding friction, chemical irritants, and trauma is key. Use gentle cleansing with mild, unscented soap and pat the skin dry, choose loose, breathable clothing, and avoid adhesives, perfumes, or harsh products on the site. Sun exposure should be avoided on the treated area, and any moisturizers used should be approved by the care team and typically fragrance-free to minimize irritation. Keeping the skin protected helps prevent breakdown and promotes healing, whereas exposing the skin to sun or adding irritants would worsen the reaction.
