The school nurse is preparing a teaching pamphlet in response to requests from parents regarding an outbreak of pinworms at the local preschool. Which information about the most commonly prescribed medication, mebendazole, should be included?

A. Insert the medication as a rectal suppository: Mebendazole is administered orally, not rectally. It is typically given in tablet or chewable form. B. A second dose of medication should be given in two weeks: A second dose is recommended to eliminate any newly hatched worms, as mebendazole does not kill eggs, which helps prevent reinfection. C. Only children with perianal itching should take the medication: Pinworm infections are highly contagious; household contacts, even if asymptomatic, are often treated to prevent reinfection and spread. D. It is safe for children of all ages to take this medication: Mebendazole is not approved for use in children under 2 years of age without specific medical direction, so age-specific safety must be considered.
