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.

The lipid bilayer is made of phospholipids. They are arranged in a double layer because one of their ends is attracted to water while the other is repelled by water.

Did you know?

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
