A parent asks, “Can I get head lice too?” The nurse indicates that adults can also be infested with head lice but that pediculosis is more common among school-age children, primarily for which of the following reasons?

1. An immunity to pediculosis usually is established by adulthood.

2. School-age children tend to be more neglectful of frequent handwashing.

3. Pediculosis usually is spread by close contact with infested children.

4. The skin of adults is more capable of resisting the invasion of lice.
