A nurse is assisting with the care of a preschooler who has manifestations of respiratory syncytial virus. Which of the following actions should the nurse take?

A. Initiate droplet precautions. Respiratory syncytial virus (RSV) is primarily transmitted through respiratory secretions, requiring contact and droplet precautions to prevent the spread. Isolation measures, including wearing masks and gowns, help protect healthcare workers and other patients. B. Administer fluconazole to the preschooler. Fluconazole is an antifungal medication, which is not effective against RSV, a viral infection. Treatment for RSV is mainly supportive, focusing on airway management, hydration, and oxygen therapy as needed. C. Monitor the preschooler's urine for protein. Proteinuria is associated with kidney conditions such as nephrotic syndrome, not RSV. RSV primarily affects the respiratory system, causing bronchiolitis and increased mucus production rather than kidney involvement. D. Request an x-ray of the preschooler's neck. A neck x-ray is typically used to evaluate airway obstruction from conditions like epiglottitis. RSV affects the lower respiratory tract, leading to bronchiolitis, and does not usually require imaging unless complications arise.
