A nurse is caring for a toddler who is hospitalized with respiratory syncytial virus (RSV). Which of the following nursing interventions is the priority?

A. Fever is a common symptom of RSV, and antipyretics can improve comfort. However, fever itself is not life-threatening and does not directly address the risk of airway compromise or hypoxia. Therefore, antipyretics are secondary to interventions that support breathing and oxygenation. B. Hydration is important because RSV can cause poor oral intake, dehydration, and increased mucus viscosity, which may worsen airway obstruction. While promoting fluids is necessary, it is not as urgent as ensuring adequate oxygenation. C. Continuous monitoring of oxygen saturation allows for early detection of hypoxemia. Hypoxia can develop rapidly in infants and toddlers with RSV due to their smaller airway size and limited respiratory reserve. Humidified oxygen helps maintain airway moisture, reduces airway irritation, and supports gas exchange. Ensuring adequate oxygenation prevents complications such as respiratory failure, apnea, or cardiac compromise, making it the highest priority intervention. D. RSV is highly contagious and spreads via respiratory droplets and direct contact. Precautions are essential to protect staff and other patients, but infection control measures do not address the immediate threat to the patient’s respiratory status. Priority interventions must first ensure the child’s airway and oxygenation are stable.
