Answer to Question 1

ANS: B
Indirect calorimeters contain analyzers for measuring the concentration of inspired and expired gases, oxygen (O2) and carbon dioxide (CO2), pneumotachometers, turbine flowmeters, or ultra-sonic vortex flowmeters to measure volume and flow, temperature-sensitive, solid-state trans-ducers to measure barometric pressure and exhaled gas temperatures.

Answer to Question 2

ANS: D
The electrode temperature must be documented to ensure that the temperature stays within the range of 42-45 C. The skin temperature should be noted to assess the patient's peripheral perfu-sion. The probe placement should be noted to ensure that the probe is being moved to different sites every 4-6 hours. The fractional inspired oxygen (FIO2) should be documented to determine the need for an increase or decrease in the amount of supplemental oxygen the patient is receiv-ing.
