What instruction should a nurse provide to a patient who has undergone a modified radical mastectomy and is starting radiation therapy?

For a patient who has undergone a modified radical mastectomy and is beginning radiation therapy, the guidance to wash the area gently with lukewarm water and pat it dry is based on the need to maintain skin integrity while ensuring the radiation treatment area remains clean.

This approach helps minimize the risk of skin irritation and infection, which is crucial because the skin in the radiated area can become sensitive or damaged during therapy. Gentle cleansing with lukewarm water ensures that the skin is adequately cared for without exacerbating any sensitivity or irritation. Patting the area dry, rather than rubbing, further protects the delicate skin from unnecessary friction.

Using vigorous scrubbing or harsh soaps could cause irritation or damage, which can complicate the healing process and interfere with the effectiveness of the radiation treatment. Similarly, applying lotion directly before radiation can lead to skin reactions during treatment. Leaving the area completely dry without washing can result in the buildup of perspiration, dirt, or bacteria, which increases the risk of infection and skin issues. Thus, the correct instruction promotes optimal care of the skin as the patient progresses through radiation therapy.
