The nurse is caring for a preschooler with acute nasopharyngitis. Which information should the nurse include when teaching the parents about this health problem?

A. Coughing helps to clear mucus from the airways, and suppressing it can lead to complications such as mucus buildup and infection. B. Antibiotics are not prescribed for viral infections like the common cold unless there is a secondary bacterial infection. C. Ear pulling may indicate ear discomfort or infection, but it is not a typical response to nasopharyngitis alone. D. It is normal for young children to have multiple colds per year due to their developing immune systems.
