A nurse is planning a staff in-service about infection control measures to prevent the spread of influenza in school-age children. Which of the following instructions should the nurse include?

A. "Wear a face mask when working within 3 feet of a child who is infected.": Influenza is primarily transmitted via large respiratory droplets, which can spread up to 3 feet. Wearing a face mask within this distance helps prevent transmission to healthcare workers and others. B. "Administer the influenza vaccine every 6 months.": The influenza vaccine is administered annually, not every 6 months. Protection from the vaccine is designed to last through one flu season, and a yearly update is needed due to viral strain changes. C. "Children should be considered infectious for 14 days after the onset of symptoms.": Most children with influenza are considered infectious from 1 day before symptom onset until about 5–7 days after. 14 days is unnecessary unless the child is severely immunocompromised. D. "Administer antibacterial medication within 24 hr of the onset of symptoms.": Influenza is a viral infection, so antibacterial medications are ineffective. Antiviral medications, such as oseltamivir, may be considered within 24–48 hours, but antibiotics are not appropriate.
