Answer to Question 1

ANS: C
Intubated patients receiving mechanical ventilatory support typically have a Raw of 5 to 10 cm H2O/L/sec.

Answer to Question 2

ANS: B
Positive pressure ventilation (especially with PEEP), pulmonary embolism, cardiac arrest, and pulmonary hypoperfusion also may cause an increase in PaCO2 to PETCO2 gradient P(aET)CO2. Exercise and a large tidal volume can reverse the P(aET)CO2 gradient, the PETCO2 can actually exceed the PaCO2.
