Which instruction regarding skin care should the nurse provide to a client who is receiving radiation therapy for metastatic breast cancer?

The excoriated and red skin in the diaper area suggests the presence of diaper dermatitis, which is commonly caused by prolonged exposure to moisture and irritants such as urine and feces. Changing the diaper more frequently helps to minimize the exposure to these irritants and promotes better skin hygiene.

Asking the mother to decrease the infant's intake of fruits for 24 hours is not necessary unless there is evidence of diarrhea or specific dietary concerns. Fruits are generally a healthy part of an infant's diet and do not directly cause diaper dermatitis.

Encouraging the mother to apply lotion with each diaper change may not be recommended in this case, as lotions and creams can further trap moisture and exacerbate the condition. It is best to keep the area clean and dry.

Telling the mother to cleanse with soap and water at each diaper change may be too harsh for the infant's sensitive skin. Plain water or mild, fragrance-free wipes are typically sufficient for cleaning the diaper area. Soap can be drying and irritating to the skin, so it is generally not necessary unless there is a specific indication.

These findings suggest potential complications and compromise to the client's circulation and nerve function, which require immediate attention.

Changes in the quality of peripheral pulses indicate alterations in blood flow and may suggest vascular compromise or decreased perfusion to the affected areas. This finding requires immediate intervention to prevent further damage and ensure adequate blood supply to the extremities.

Loss of sensation to the left lower extremity can be indicative of nerve injury or impaired peripheral nerve function. It is important to assess for nerve damage and address it promptly to prevent complications and maximize the client's recovery.

Complaints of increased pain and pressure are concerning because they may indicate the development of compartment syndrome, a serious complication in which pressure within the muscles and tissues builds up to dangerous levels. Prompt intervention is necessary to relieve the pressure and prevent tissue damage.

While sloughing tissue around wound edges and weeping serosanguineous fluid from wounds are important assessment findings in the context of burn care, they do not require immediate intervention compared to the findings mentioned above. These findings should still be addressed and managed appropriately, but they are not considered immediate emergencies.
