A nurse is reinforcing teaching with the guardian of a preschooler who has varicella and is hospitalized. Which of the following statements by the guardian indicates an understanding of the teaching?

A. Wearing a mask when visiting the child despite having had chickenpox is incorrect. If the guardian has already had chickenpox or received the varicella vaccine, they are immune and do not need to wear a mask when visiting the child. However, individuals who are immunocompromised or have never had chickenpox should take precautions. B. Taking the child to the playroom after all lesions have crusted is correct. Varicella (chickenpox) is contagious until all lesions have crusted over, which usually takes about 5 to 7 days. Once crusting has occurred, the virus is no longer actively transmissible, and the child can safely interact with others. C. Expecting the child to remain on bedrest for 3 days is incorrect. Bedrest is not a requirement for varicella unless the child has complications such as a high fever or severe discomfort. Activity should be based on the child's energy levels and overall condition. D. Waiting to bathe the child until the crusts have fallen off is incorrect. Bathing can be done while the child still has crusted lesions, as long as the water is lukewarm and soap is mild. Oatmeal or baking soda baths can help soothe itching and prevent infection.
