A 3-year-old boy in a daycare facility scratches his head frequently, and the nurse confirms the presence of head lice. The nurse washes the child's hair with permethrin shampoo and calls his parents. Which instruction should the nurse provide to the parents about treatment for head lice?

The nurse should instruct the parents to wash the child's bed linens and clothing in hot soapy water to kill any remaining head lice and prevent reinfestation. The child's brushes, combs, and other hair accessories should also be washed in hot soapy water or disposed of. Taking the child to a hair salon for a shampoo and a shorter haircut is not necessary for treatment of head lice. Rewashing the child's hair following a 24-hour isolation period is not necessary if the permethrin shampoo has been used as directed.
