Answer to Question 1

ANS: C
A value of 1 Hz is 60 cycles/min. Therefore, 15 Hz  60 cycles/min = 900 cycles/min.

Answer to Question 2

ANS: A
If a change in the airway pressure occurs because another control has been adjusted, the mean pressure adjust control knob should be used to return the airway pressure to the desired level.
