An oncology nurse is caring for a client who developed erythema after radiation therapy. What instruction should the nurse give?

• A. Periodically apply ice to the area.
• B. Keep the area cleanly shaven.
• C. Apply petroleum jelly to the affected area.
• D. Avoid using soap on the treatment area.

Answer: (D)

Radiation-treated skin is very sensitive and easily irritated, so cleansing should be gentle and free of irritants. Avoiding soap on the treatment area helps minimize drying, friction, and chemical irritation that can worsen dermatitis, itching, and cracking. If cleansing is needed, plain water or a mild, fragrance-free cleanser used sparingly, followed by patting the skin dry, supports healing without adding irritation. Other common-sense steps, like shaving or applying creams without guidance, can disturb the area and complicate recovery, so they’re best discussed with the care team.
