Answer to Question 1

ANS: C
The resistance or the expiration through the pursed lips causes a backflow of air and helps to open the bronchioles.

Answer to Question 2

ANS: A
Tidaling or fluctuation in the water seal drainage is an indicator that the negative pressure is preserved and the system is working normally. Document this normal finding.
