Answer to Question 1

ANS: D
Many instrumentation companies manufacture laboratory blood gas analyzers. Although available in a range of designs, these devices typically share the following key components:
 An operator interface (e.g., operating controls, light-emitting diode LED or cathode ray tube CRT displays, keypads, software)
 A measuring chamber incorporating the typical three-electrode system
 Calibrating gas tanks
 Reagent containers (buffers used for calibration, rinse solutions)
 A waste container
 A results display, storage, and transmittal system (e.g., screen, printer, disk storage device, network interface)

Answer to Question 2
