A nurse is providing teaching to the guardians of a child who has respiratory syncytial virus (RSV). Which of the following information should the nurse include?

A. Administer an antibiotic to the child for 10 days: RSV is a viral infection, and antibiotics are ineffective against viruses. Antibiotics are only indicated if a secondary bacterial infection develops. Routine antibiotic therapy does not treat RSV and should not be included in teaching. B. Cyclophosphamide can be given to decrease the duration of the infection: Cyclophosphamide is an immunosuppressive chemotherapy agent and has no role in treating RSV. Administering this medication would be inappropriate and harmful in a child with a viral respiratory infection. C. Wear an N95 mask when in direct contact with the child: Standard precautions for RSV involve contact and droplet precautions, typically including a surgical mask, gloves, and gown. An N95 mask is not required for routine care of RSV, as transmission risk is primarily via contact with secretions and large respiratory droplets. D. RSV is transmitted by direct contact with respiratory secretions: RSV spreads through close contact with contaminated secretions from coughing, sneezing, or touching surfaces. Teaching guardians about transmission helps prevent spread and reinforces the importance of hand hygiene and infection control measures in the home.
