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?

Rationale: A. Respiratory syncytial virus (RSV) is a viral infection, not a bacterial infection. Antibiotics are not effective against viruses and are only used if there is a secondary bacterial infection, which is not routine. Supportive care (oxygen, hydration, suctioning) is the main treatment. B. Cyclophosphamide is a chemotherapy and immunosuppressive agent, not used to treat RSV. There is no role for this medication in managing RSV. In fact, immunosuppression would worsen the infection. C. RSV is primarily transmitted via contact and droplet spread, not airborne transmission. Standard and contact precautions (including gloves, gown, and hand hygiene) are typically sufficient. An N95 respirator is not required unless there is another indication for airborne precautions. D. RSV spreads through direct contact with infected respiratory secretions and contaminated surfaces (fomites). It is highly contagious, especially in young children, and can survive on surfaces for several hours. Strict hand hygiene and contact precautions are essential to prevent transmission.
