A nurse is reinforcing teaching with a parent of a child who has acute group A ẞ-hemolytic streptococci. Which of the following instructions should the nurse include in the teaching?

A. Keep the child home from school for at least 1 week: The child should stay home for at least 24 hours after starting antibiotics, not 1 week, to prevent spreading the infection. B. Intramuscular injections will be required monthly: This is incorrect. Monthly intramuscular injections of penicillin are used for prophylaxis to prevent rheumatic fever, not for the treatment of acute group A β-hemolytic streptococcal infections. C. Avoid the use of warm compresses around the head or neck: Warm compresses are not contraindicated for sore throats associated with group A strep infections unless there is an abscess or specific complication. This statement is not relevant. D. Replace the child's toothbrush after 24 hours of taking antibiotics: The toothbrush should be replaced after 24 hours to prevent re-infection, as the child may still have bacteria in their mouth that can reintroduce the infection.
