Answer to Question 1

ANS: A
Arterial blood gases typically show hypoxemia with mixed respiratory and metabolic acidosis.

Answer to Question 2

ANS: B
Infants with MAS typically have gasping respirations, tachypnea, grunting, and retractions. The chest radiograph usually shows irregular pulmonary densities, which represent areas of atelectasis, and hyperlucent areas, which represent hyperinflation due to air trapping.
