Answer to Question 1

ANS: D
The right bronchus branches off from the trachea at an angle of approximately 20 to 30 degrees, and the left bronchus branches with an angle of approximately 45 to 55 degrees (Figure 9-44). The right bronchus's lower angle of branching results in a greater frequency of foreign body pas-sage into the right lung because of the more direct pathway.
