Answer to Question 1

A
TTN and the early stage of respiratory distress syndrome (RDS) have an initially similar clinical presentation.

Answer to Question 2

D
Compression of the lung tissue occurs beneath the flail section and atelectasis results. The atelectasis then results in a decreased ventilation/perfusion ratio leading to increased venous admixture. Hypoxemia will occur.
