Answer to Question 1

ANS: C
The PO2 is determined by measuring current changes that occur as oxygen is reduced, hence the technique represents an amperometric measurement. The blood gas factor is a phenomenon due to the slow rate of oxygen diffusion in fluids (i.e., oxygen consumed by an electrode is not replaced by oxygen from the blood). Measurements based on voltage changes are called potentiometric measurements. Tonometry is a measure of pressure and a method of quality control for arterial blood gas machines.

Answer to Question 2

ANS: A
Between the Teflon membrane and the pH glass electrode is a bicarbonate-buffered solution. A mercury bead is part of a pH electrode. A KCl solution is used in the pH electrode. A silver an-ode is used in the Clark electrode.
