Answer to Question 1

D
The major pathologic or structural changes associated with MAS due to the physical presence of the meconium include partially obstructed airways, air trapping, alveolar hyperinflation, pulmonary air leak syndromes (pneumomediastinum or pneumothorax), and totally obstructed airways and absorption atelectasis. They do not include pulmonary edema and alveolar flooding.

Answer to Question 2

B
Although full bone healing will not be complete, 5 to 10 days of ventilatory support should allow sufficient healing of the flail area.
