A 4 year old child presents with varicella and vesicular rash in various stages of healing. Which statement by the parent indicates understanding of the teaching?

I can give my children's spin for fever

Once the fever has gone away my child can go back to school

Once some of the lesions are crusted over, the child is not contagious

I can use cool/tepid water to sponge-bathe my child while the lesions are present
