Answer to Question 1

ANS: C
Refer to Figure 10-4 on page 324, which shows a schematic of the pH electrode.

Answer to Question 2

ANS: C
A prolonged delay between obtaining and analyzing a specimen (i.e., longer than 5 minutes) can lead to erroneous results. This problem is particularly evident in patients with high leukocyte counts. Chilling the specimen to below 5 C by placing the syringe in ice water can reduce the metabolic rate of the white blood cells, minimizing this problematic effect.
