Answer to Question 1

B
If the newborn infant is hypoxemic and has an inadequate inspiratory effort, there is a delay in the clearance of pulmonary fluid. This leads to TTN.

Answer to Question 2

C
Paradoxical chest movement means that the flail area moves in the opposite direction from which it normally would. So, with inspiration, the flail area moves inward, and with exhalation, the flail area moves outward. The tracheal position is not affected by broken ribs.
