Nokea
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.

What is most important in the management of cellulitis?
- A. Burow solution compresses
- B. Oral or parenteral antibiotics
- C. Topical application of an antibiotic
- D. Incision and drainage of severe lesions
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.
What is the primary treatment for warts?
- A. Vaccination
- B. Local destruction
- C. Corticosteroids
- D. Specific antibiotic therapy
Correct Answer: B
Rationale: Local destructive therapy is individualized according to location, type, and number; surgical removal, electrocautery, curettage, cryotherapy, caustic solutions, x-ray treatment, and laser therapies are used. Vaccination is prophylaxis for warts, not a treatment. Corticosteroids and specific antibiotic therapy are not effective in the treatment of warts.

- D. Staphylococcal scalded skin

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.
