What is an important instruction a nurse should give a mother applying permethrin to her child diagnosed with head lice?

Wearing gloves when applying permethrin cream is a critical instruction for several reasons. First, permethrin is a topical insecticide, and direct skin contact with it should be minimized to prevent any potential irritation or adverse reactions. This is particularly important when applying the treatment to a child, as children's skin can be more sensitive than adults’. Gloves help protect the caregiver’s hands from exposure to a chemical that can be irritating.

In addition, using gloves prevents cross-contamination. The application process might involve touching various surfaces or items that could transfer the insecticide; wearing gloves ensures that the product remains on the intended area (the child’s scalp) and does not inadvertently end up on the caregiver or surrounding items.

While there are other considerations regarding permethrin application, such as ensuring the hair is dry or the treatment is left on for a specified duration, the safeguard of using gloves is paramount for the safety of both the caregiver and the child during this process.
