A mother brings her 8-year-old daughter into the clinic where you are a nurse. The girl has a dry, flaky, and peeling rash around her mouth. The mother states that she has tried using numerous lotions, but the lesions persist. She has come here looking for information on how to make her daughter stop licking her lips, as she thinks this is causing the lesions. Upon closer examination, you notice small blisters and honey-colored crusts. You note that the patient is negative for other symptoms, including fever, nausea, vomiting, and general malaise. As you suspect, the diagnosis of the lesions is S. aureus impetigo. The mother then asks you why her daughter's affected skin seems so fragile and blisters so easily. What will be your response to her question?

A) "The constant exposure to moisture makes your daughter's skin very fragile, and blistering is the natural response."
B) "Your daughter's constant itching irritates the skin, making it very fragile and irritable."
C) "The blood beneath the surface of the skin is broken down by waste products from S. aureus, and superficial blisters are the clinical sign."
D) "A toxin produced by S. aureus targets a protein responsible for cell-to-cell binding, and blisters are the result.
