What findings on a chest radiograph would be expected during a prolonged asthma episode?
1. Depressed diaphragm
2. Increased anterior-posterior diameter
3. Asymmetrical lung inflation
4. Translucent lung fields
a. 1, 2
b. 3, 4
c. 1, 2, 4
d. 1, 2, 3, 4
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.
