Answer to Question 1

A
On the PA projection the ratio of the width of the heart to the thorax (the cardiothoracic ratio) is normally less than 1:2 . In other words, normally the width of the heart should be less than 50 of the width of the thorax.

Answer to Question 2

D
Early on, when an infant is having respiratory distress, he or she will show cyanosis, sternal retractions, expiratory grunting, and other signs. He or she will have apnea and other signs later on.
