  b. 3 and 5 d. 1, 4, and 5

Question 2

Which of the following statements is true concerning quality control of a blood gas analyzer?
 
  a. Commercially prepared controls ensure instrument accuracy.
  b. A Levy-Jennings chart is used to record quality control data.
  c. Protein buildup on electrodes will not cause errors in the instrument.
  d. Commercial controls are not susceptible to variations at room temperature.

Question 3

Which of the following in vivo arterial blood gas values is comparable with in vitro measure-ments?
 
  a. pH c. PO2
  b. PCO2 d. Bicarbonate

Answer to Question 1

ANS: A
CAP and ATS currently offer two proficiency testing programs that provide a means of assessing blind samples (periodically) and the technical competence of laboratory personnel, as well as a means of reporting the variability of individual blood gas analyzers.

Answer to Question 2

ANS: B
The most common method of recording quality control data involves the use of Levy-Jennings charts. These charts allow the operator to detect trends and shifts in electrode performance, which helps prevent problems associated with reporting of inaccurate data because of analyzer malfunction. Commercially prepared control systems provide information on the instrument's precisionnot the accuracy of the dataand are susceptible to variations in room storage tem-perature.

Answer to Question 3

ANS: A
Compared with in vitro blood gas analysis, intra-arterial blood gas monitoring systems are com-parable for pH, but the correlation may not be as good for PCO2 and PO2 measurements.
