Answer to Question 1

C
As the infant with a CDH and respiratory distress generates a more negative inspiratory pressure to breathe, more of the gastrointestinal structures are sucked into the thorax. This worsens the existing problem.

Answer to Question 2

B
Because of alveolar destruction, patients with emphysema will have decreased gas diffusion. A decreased DLCO is a classic diagnostic sign of emphysema. The DLCO is normal in pure chronic bronchitis.
