Answer to Question 1

ANS: C
Closed-circuit calorimeters can be used for both spontaneously breathing and mechanically ven-tilated patients. Open-circuit devices can also be used for both spontaneously breathing and me-chanically ventilated patients. However, special problems can arise when systems are used with mechanically ventilated patients. Some of these problems include fluctuations in FIO2, separation of the patient's inspired and expired gases from the continuous gas flow provided by the venti-lator, and handling of water vapor.

Answer to Question 2

ANS: B
Calorimetry is a method of determining energy expenditure by using the measurements of the amount of heat radiated and absorbed by an organism.
