Answer to Question 1

ANS: D
Remember that waste fluids are potentially infectious and should be handled as if they were blood samples. In addition, the National Committee for Clinical Laboratory Standards recom-mends adding a strong disinfectant, such as 2 glutaraldehyde or a 1:4 solution of sodium hy-pochlorite, to the instrument's waste container either during use or before disposal.

Answer to Question 2

ANS: A
To measure PCO2, blood gas analyzers use the Severinghaus electrode, which is essentially a pH electrode exposed to an electrolyte solution that is in equilibrium with the sample through a car-bon dioxidepermeable membrane.
