Answer to Question 1

ANS: C
The base flow is the bias or background flow that is present during the expiratory phase. That flow is the set base flow, or 10 L/min in this case.

Answer to Question 2

ANS: A
Pressure triggering usually is set at 0.5 to 1.5 cm H2O. This means that the trigger will occur at 0.5 to 1.5 cm H2O below the baseline pressure.
