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?

Choice A rationale: This statement reflects an accurate understanding of varicella (chickenpox) transmission and infection control. The lesions of varicella contain the virus and are contagious until they have crusted over. Allowing the child to go to the playroom only after the lesions have crusted helps prevent the spread of the virus to other individuals. Choice B rationale: This statement is incorrect because waiting for the crusts to fall off the lesions before bathing the child is not necessary. In fact, keeping the lesions clean and maintaining proper hygiene through gentle bathing can help prevent secondary bacterial infections. Choice C rationale: This statement is incorrect because bedrest for 3 days is not necessary for a child with varicella. While it's important to minimize contact with others during the contagious phase, physical activity can be gradually resumed as long as the lesions have crusted to prevent transmission. Choice D rationale: This statement is incorrect. Once a person has had chickenpox (varicella), they develop immunity to the virus and do not need to wear a mask when visiting someone with active varicella. This is because they are already immune to the virus due to their prior infection.
