What should the nurse explain about ringworm?
- A. It is not contagious.
- B. It is a sign of uncleanliness.
- C. It is expected to resolve spontaneously.
- D. It is spread by both direct and indirect contact.
Correct Answer: D
Rationale: Ringworm is spread by both direct and indirect contact. Infected children should wear protective caps at night to avoid transfer of ringworm to bedding. Ringworm is infectious. Because ringworm is easily transmitted, it is not a sign of uncleanliness. It can be transmitted by seats with head rests, gym mats, and animal-to-human transmission. The drug griseofulvin is indicated for a prolonged course, possibly several months.

The school reviewed the pediculosis capitis (head lice) policy and removed the no nit requirement. The nurse explains that now, when a child is found to have nits, the parents must do which before the child can return to school?
- A. No treatment is necessary with the policy change.
- B. Shampoo and then trim the childs hair to prevent reinfestation.
- C. The child can remain in school with treatment done at home.
- D. Treat the child with a shampoo to treat lice and comb with a fine-tooth comb every day until nits are eliminated.
Correct Answer: C
Rationale: Many children have missed significant amounts of school time with no nit policies. The child should be appropriately treated with a pediculicide and a fine-tooth comb. The environment needs to be treated to prevent reinfestation. The treatment with the pediculicide will kill the lice and leave nit casings. Cutting the childs hair is not recommended; lice infest short hair as well as long. With a no nit policy, treating the child with a shampoo to treat lice and combing the hair with a fine-tooth comb every day until nits are eliminated is the correct treatment. The policy change recognizes that most nits do not become lice.
