Answer to Question 1

ANS: D
Tracheal stenosis will appear as a fixed obstructive pattern, with flattening of both the inspiratory and expiratory limbs of the flow-volume loop (Figure 36-25).

Answer to Question 2

ANS: C
The tube tip should be approximately 3 to 6 cm above the carina in adults, or between the second and fourth tracheal rings.
