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.

- A. Corticosteroids
- B. Oral griseofulvin

Pertussis vaccination should begin at which age?
- A. Birth
- B. 2 months
- C. 6 months
- D. 12 months
Correct Answer: B
Rationale: The acellular pertussis vaccine is recommended by the American Academy of Pediatrics beginning at age 6 weeks. Infants are at greater risk for complications of pertussis. The vaccine is not given after age 7 years, when the risks of the vaccine become greater than those of pertussis. The first dose is usually given at the 2-month well-child visit. Infants are highly susceptible to pertussis, which can be a life-threatening illness in this age group.
What is most important in the management of cellulitis?
- A. Burow solution compresses
- B. Oral or parenteral antibiotics

Correct Answer: B
Rationale: Oral or parenteral antibiotics are indicated depending on the extent of the cellulitis. Warm water compresses may be indicated for limited cellulitis. The antibiotic needs to be administered systemically. Incision and drainage of severe lesions presents a risk of spreading infection or making the lesion worse.
