When a closed Thorpe tube flowmeter is attached to a 50-psi oxygen source, the indicator float jumps up then quickly falls to zero. This flowmeter is:
 
  a. broken. c. compensated for back pressure.
  b. a Bourdon gauge flowmeter. d. uncompensated for back pressure.

Question 2

Answer to Question 1

ANS: C
A flowmeter can be determined to be pressure-compensated if the following test is performed: With the needle valve closed, the flowmeter is plugged into a high-pressure gas source. If the float in the indicator tube jumps and then falls to zero, the flowmeter is pressure-compensated. The float movement occurs because the source gas must pass through the indicator tube before it reaches the needle valve.

Answer to Question 2

ANS: B
Nasal cannulas are inexpensive and allow the patient to eat, drink, and speak while receiving ox-ygen. Nasal cannulas cannot deliver precise oxygen concentrations, and pressure necrosis is pos-sible because of the pressure points where the tubing holds the cannula in place touch the pa-tient's face and ears.
