Answer to Question 1

ANS: D
Pulse, arterial blood pressure, and minute volume normally increase as the patient breathes car-bogen, but the rapidity and level of these changes depend on the concentration of the mixture.

Answer to Question 2

ANS: D
For non-intubated patients, a well-fitted nonrebreathing mask attached to a reservoir bag should be used. The flow rate of gas should be high enough to prevent the reservoir bag from collapsing during inspiration. Nasal cannulas are ineffective for delivering heliox because of leakage; in-stead, nonrebreathing masks are the most effective.
