Answer to Question 1

d
Rationale: a. This answer best describes a venture mask.
b. Intubation is the best choice when a patient can not protect or maintain their airway.
c. Incorrect.
d. Correct.

Answer to Question 2

Exhalation begins when the diaphragm relaxes, resuming its resting dome shape. The elastic tissue of the lungs also recoils. Together, these actions make the chest cavity smaller. The pressure inside the chest cavity rises, and air is forced out.
