Answer to Question 1

ANS: C
The transcutaneous partial pressure of carbon dioxide (PtcO2) electrode is heated to between 42 C and 45 C to produce capillary vasodilation below the surface of the electrode. This will im-prove diffusion of gases across the skin. If the PtcO2 temperature is lower than this range, the re-sults will not be reliable. A temperature higher than this range will produce skin burns.

Answer to Question 2

ANS: B
A heated Clark or polarographic electrode is used to monitor the transcutaneous partial pressure of oxygen. The Stow-Severinghaus electrode is used in the measurement of transcutaneous car-bon dioxide (CO2) partial pressure. Polarographic and Galvanic electrodes are types of oxygen analyzers that use chemical reactions to measure oxygen concentrations in gas mixtures.
