🏥 USMLE Exam Prep

A 6-month-old infant presents to the emergency department with a 3-day history of rhinorrhea, cough, and progressively worsening respiratory distress, including tachypnea and nasal flaring. Physical examination reveals diffuse wheezing and crackles. The oxygen saturation is 92% on room air. What is the most appropriate management for this infant?

A Oral corticosteroids
B Inhaled bronchodilators (e.g., albuterol)
C Supportive care with humidified oxygen and nasal suctioning
D Broad-spectrum intravenous antibiotics

✓ Correct Answer: Option C

This clinical picture is classic for bronchiolitis, typically caused by RSV. Management is primarily supportive, focusing on maintaining adequate hydration and oxygenation, often with humidified oxygen and nasal suctioning. Bronchodilators, steroids, and antibiotics are generally not recommended for routine management.
