Answer to Question 1

C
Because of the air trapping that occurs during an asthma attack, the lungs are hyperinflated. The diaphragm is depressed or flattened by the trapped air and the anterior-posterior diameter would be increased. A more subtle change would be darkened lung fields caused by the increased air within the alveoli.

Answer to Question 2

A
With an AP projection, the heart is enlarged because the x-rays enter from the front and exit from the back to the film (see Fig. 7-3). A PA and left lateral film will show the heart at the correct size. The same is true of a CT scan.
