A mother has noticed that her son, who has been to a new babysitter, has some blisters and scabs on his face and buttocks. On examination, the nurse notices moist, thin-roofed vesicles with a thin erythematous base. What does the nurse suspect?

A) Eczema
B) Impetigo
C) Herpes zoster
D) Diaper dermatitis

Impetigo is moist, thin-roofed vesicle with a thin erythematous base and is a contagious bacterial infection of the skin and most common found in infants and children. Eczema is characterized by erythematous papules and vesicles with weeping, oozing, and crusts. Herpes zoster (i.e., chickenpox or varicella) is characterized by small, tight vesicles that are shiny with an erythematous base. Diaper dermatitis is characterized by red, moist maculopapular patches with poorly defined borders. The moist, thin vesicles that look like blisters and scabs on the buttocks are likely impetigo.
