A. It is recommended to replace the child's toothbrush after 24 hours of starting antibiotics to prevent reinfection or spreading the bacteria. B. A child with acute group A B-hemolytic streptococci should remain home from school until they have been on antibiotics for at least 24 hours, not for a full week, to reduce the risk of spreading the infection. C. Warm compresses may be used to alleviate discomfort associated with sore throats or swollen glands; there is no contraindication to their use in this context. D.
