A nurse is providing teaching to a parent of a child who has varicella. Which of the following statements should the nurse include in the teaching?

A) The statement about returning to school once the fever has subsided is not sufficient for varicella. Children should not return until the lesions have crusted over to prevent spreading the infection. B) The recommendation that the child can return to school once the lesions have crusted over is accurate. Varicella is contagious from 1 to 2 days before the rash appears until all lesions have crusted over, which usually occurs about 6 days after the onset of the rash. C) A negative titer result is not necessary for a child to return to school. Immunity can be confirmed through vaccination history or prior infection; thus, this statement is misleading. D) Since varicella is a viral infection, antibiotics are not indicated for treatment. Therefore, stating that the child can return to school 24 hours after beginning antibiotics is incorrect and could lead to misunderstanding about the management of the illness.
