Pharmacological and Parenteral TherapiesQuestion 1274 of 2368
The nurse teaches a parent about treating a child's head lice with a topical pediculicide. Why must the treatment be repeated in 7 to 10 days?
- The pediculicide does not kill the nits.
- The pediculicide stops working after 24 hours.
- The pediculicide can only be used once a week.
- The lice grow resistant after the first treatment.
Show answer
Correct answer: The pediculicide does not kill the nits.
Pediculicides do not kill nits, so a second treatment kills lice that hatch later.
