Answer to Question 1

B
The most reliable and accurate means of delivering a prescribed concentration of oxygen is through the use of a nonrebreathing circuit (closed).

Answer to Question 2

B
Tachypnea is manifested by an increase in the rate and decrease in the depth of ventilation. Hyperventilation is manifested by an increase in both the rate and depth of ventilation. Obstructive breathing is characterized by progressively more shallow breathing until the client actively and forcefully exhales. Bradypnea is a slow respiratory rate characterized as less than 12 breaths/min in an adult.
