Answer to Question 1

ANS: B
The only factor limiting the use of a pressure-compensated Thorpe tube is gravity. Because it is accurate only in an upright position, a Thorpe tube is not the ideal choice for patient transport. In these cases, the gravity-independent Bourdon gauge is a satisfactory alternative.

Answer to Question 2

ANS: B
The scale of the compensated Thorpe tube flowmeter is calibrated at 50 psig instead of at at-mospheric pressure.
