Answer to Question 1

ANS: C
The trachea shifts away from areas with increased air, fluid, or tissue (e.g., in tension pneumo-thorax or large pleural effusion) and toward atelectasis. In general, abnormalities in the lung bases do not shift the trachea.

Answer to Question 2

ANS: B
Breathing through pursed lips during exhalation creates resistance to flow. The increased re-sistance causes development of a slight backpressure in the small airways during exhalation, which prevents their premature collapse and allows more complete emptying of the lung.
