Answer to Question 1

ANS: C
A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: Exhaled CO2 gas concentration can be measured via infrared absorption technology.
D. Incorrect response: See explanation C.

Answer to Question 2

ANS: D
A. Incorrect response: See explanation D.
B. Incorrect response: See explanation D.
C. Incorrect response: See explanation D.
D. Correct response: When either an inspiratory pause or an expiratory hold maneuver is performed on a patient receiving mechanical ventilation, the recorded pressure reflects alveolar pressure. The pressure is sometimes called the alveolar distending pressure.
