Answer to Question 1

A
Pneumomediastinum is associated with a pulmonary air leak syndrome. RSV can lead to a decreased airway lumen or partial or complete airway obstruction.

Answer to Question 2

B
Peribronchiolar mononuclear infiltration and small airway epithelial necrosis are anatomic alterations of the lungs found with RSV. Meconium aspiration syndrome can cause a chemical pneumonitis of the small airways. Croup syndrome is associated with edema of the epiglottis and upper airway.
