Final answer:
Option B. The nurse should advise the client to frequently apply moisturizers to prevent dry skin, gently pat the skin dry after rinsing with water, and protect the site from getting wet during bathing.
Step-by-step explanation:
The nurse should provide the instruction to the client to frequently apply moisturizers to prevent dry skin during radiation therapy for metastatic breast cancer. Radiation therapy can often cause dry and irritated skin as a side effect. Applying moisturizers regularly can help keep the skin hydrated and prevent dryness.
Additionally, it is important to gently pat the skin dry after rinsing with water. This helps to minimize friction and further irritation to the skin.
However, it is necessary to protect the site from getting wet during bathing. Excessive exposure to water can further exacerbate skin dryness and irritation. It is advisable to cover the site with a waterproof dressing or use a plastic wrap to protect it from getting wet.
