A nurse is preparing a child who has suspected bacterial meningitis for a lumbar puncture. Which of the following cerebrospinal fluid findings supports the diagnosis?

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.

The correct answer is Choice D.

Choice A rationale: Administering an oral corticosteroid is not the first action the nurse should take. Corticosteroids are used to reduce inflammation and itching caused by poison ivy. However, they are usually prescribed if the symptoms are severe or if the rash covers a large area of the body. It’s important to note that corticosteroids can have side effects, especially when used for a long time, so they should be used under the supervision of a healthcare provider.

Choice B rationale: Applying calamine lotion to the affected area can help soothe the skin and relieve itching caused by poison ivy. However, this is not the first action the nurse should take. The first step is to remove the oil from the skin that causes the allergic reaction. Calamine lotion can be applied after the area has been thoroughly washed.

Choice C rationale: Instructing the parent to give the child an oatmeal bath twice daily can help soothe the skin and relieve itching. However, this is not the first action the nurse should take. Similar to calamine lotion, an oatmeal bath can be beneficial after the area has been thoroughly washed to remove the oil from the skin.

Choice D rationale: The first action the nurse should take when caring for a child exposed to poison ivy is to flush the area with cold, running water. This helps to remove the oil (urushiol) from the skin that causes the allergic reaction. It’s important to do this as soon as possible after exposure to help prevent the spread of the oil to other areas of the body or to other people. After flushing the area, the nurse can then apply calamine lotion or recommend an oatmeal bath to help soothe the skin and relieve itching.
