Answer to Question 1

ANS: C
Although tonometry remains the gold standard for quality control of PCO2 and PO2 electrodes, most laboratories use commercially prepared quality control systems for biosafety and conven-ience.

Answer to Question 2

ANS: C
Quality control is the system that entails the analysis of control samples and assessment of the measurements against defined limits, identification of problems, and specification of corrective actions. The analysis of unknown samples and submitting the analysis results to a sponsoring or-ganization is known as proficiency testing.
