A child is starting antibiotic therapy for bacterial conjunctivitis. The parents ask when the child may return to daycare. The nurse's BEST response would be which of the following?

The correct answer is B: Your child can return after 24 to 48 hours of antibiotic use, depending on your school. Antibiotics for bacterial conjunctivitis are usually effective within 24-48 hours. The child becomes non-contagious after starting treatment, hence it is safe to return to daycare. Requiring completion of the full course of antibiotics (Choice D) is unnecessary for the purposes of preventing spread. Choices A and C do not consider the effectiveness of the antibiotics in reducing contagion.
