Your patient just had an anteroposterior chest film taken. When you view the film, what may be a consideration?

a. The lungs may appear smaller than they really are.
b. The heart may appear less dense then it really is.
c. The ribs may appear more horizontal than normal.
d. The heart may appear larger than it really is.

ANS: D
The closer x-ray source and the position of the patient both lead to a slight magnification of the heart shadow.
