A nurse is reinforcing teaching with the guardian of a child who has head lice. Which of the following statements should the nurse make?

A. "Apply petroleum jelly to your child's scalp at bedtime for 3 days." is incorrect. Petroleum jelly is not an effective treatment for head lice. The recommended treatment includes medicated shampoos or topical pediculicides specifically designed to kill lice. B. "Leave your child's nonwashable items in a sealed plastic bag for 2 days." is incorrect. Lice can survive on items such as hats, stuffed animals, and bedding for up to 48 hours, but it is recommended to seal nonwashable items in a plastic bag for at least 2 weeks, not 2 days, to ensure the lice die. C. "Submerge your child's combs and hairbrushes in boiling water for 10 minutes." is correct. Lice and nits can survive on combs and brushes, so disinfecting them by soaking in boiling water for at least 10 minutes effectively kills any remaining lice or eggs. D. "Spray the carpet in your child's room with insecticide weekly for 1 month." is incorrect. Insecticide sprays are not recommended for treating head lice in the home environment. Vacuuming furniture and carpets and washing bedding in hot water are more effective and safer approaches.
