A nurse is planning care for an 8-month-old infant who has bronchiolitis. Which of the following actions should the nurse include in the plan of care?

Care for an infant with bronchiolitis focuses on managing airway obstruction and respiratory distress caused by inflammation. Knowledge of the viral etiology, typically respiratory syncytial virus, and infant anatomy is necessary to prioritize supportive care measures like secretion clearance. Choice A rationale Bronchiolitis is primarily a viral infection caused by the respiratory syncytial virus. Antibiotics are ineffective against viral pathogens and are only indicated if a secondary bacterial infection is confirmed. Routine use contributes to antibiotic resistance and unnecessary side effects. Choice B rationale Infants are obligate nose breathers, and thick secretions in the nares can cause significant respiratory distress. Using a bulb syringe to clear the nasal passages maintains patency. This intervention improves oxygenation and facilitates easier feeding during the illness. Choice C rationale Negative-pressure rooms are reserved for airborne pathogens like tuberculosis or varicella. Bronchiolitis requires contact or droplet precautions depending on the facility protocol. Standard rooms with appropriate barrier precautions are sufficient for managing these viral respiratory infections. Choice D rationale The meningococcal vaccine is not indicated for an 8-month-old infant in this context. The routine schedule usually begins later in childhood or adolescence. Administering unrelated vaccines during an acute respiratory illness is clinically inappropriate and medically contraindicated..
