Answer to Question 1

ANS: D
Accuracy can be explained as how closely a measured value is related to the correct value of the quantity measured. The accuracy of any instrument depends on its linearity and frequency re-sponse, its sensitivity to environmental conditions, and how well it is calibrated.

Answer to Question 2

ANS: C
The underwater seal resistor has tubing attached to the expiratory port of the circuit and is sub-merged under a column of water. The level of continuous positive airway pressure is determined by the height of the column.
