| Where do respiratory therapists typically find DISS connections? | I. at the outlets of pressure-reducing valves attached to cylinders III. at the station outlets of central piping systems IV. at the inlets of blenders, flowmeters, ventilators, and other pneumatic equipment |
| What device is used to reduce the pressure and control the flow of a compressed medical gas? A) Bourdon gauge B) regulator C) flowmeter D) reducing valve | B) regulator |
| If you have to deliver medical gas to a patient from a compressed gas cylinder, which of the following devices would you select to control gas flow? A) regulator B) oxygen blender C) reducing valve D) flowmeter | D) flowmeter |
| To clean a cylinder valve outlet of foreign material, what should you do? A) Wipe the valve outlet with a light oil. B) Quickly open, then close, the valve. C) Blow into the valve outlet a few times. D) Wipe the valve outlet with an alcohol swab. | B) Quickly open, then close, the valve. |
| When used to control the flow of medical gases to a patient, how is a Bourdon gauge classified? | fixed-orifice, variable-pressure flowmeter device |
| What is the only major factor limiting the use of pressure-compensated Thorpe tube flowmeters? A) downstream resistance B) effect of position (gravity) C) DISS connector availability D) use with gases other than O2 | B) effect of position (gravity) |
| If you have to deliver O2 to a patient directly from a bedside outlet station, which of the following devices would you select? A) Thorpe tube flowmeter B) Bourdon type gauge C) pressure-reducing valve D) medical gas regulator | A) Thorpe tube flowmeter |
| When using a Bourdon gauge against high outflow resistance, what will the flowmeter reading show? A) higher than actual flow B) be less than actual flow C) equal actual flow D) equal 50 psi | A) higher than actual flow |
| On shoulder of a compressed gas cylinder, you note a plus sign (+) next to the test date. It indicates what about the cylinder? | It can be filled to 10% above its service pressure. |
| According to the U.S. Department of Commerce, a gas cylinder that is color coded blue should contain which of the following? A) Air B) He C) N2O D) O2 | C) N2O |
| According to the National Institute of Standards and Technology of the U.S. Department of Commerce, a gas cylinder that is color-coded brown and green should contain which of the following? A) O2–N2 mixture B) O2–CO2 mixture C) CO2 D) O2–He mixture | D) O2–He mixture |
| In clinical practice, how is a positive identification made of the contents of a medical gas cylinder? A) noting the color of the cylinder B) inspecting the cylinder threads C) reading the cylinder label D) collecting and analyzing a gas sample | C) reading the cylinder label |
| Which of the following mechanisms do all compressed gas cylinders use to avoid excessively high buildup of cylinder pressure? | pressure-relief mechanism on the valve stem |
| What safety system is designed to prevent accidental interchanging among low-pressure (less than 200 psig) connectors such as those found on flowmeters and ventilators? A) PISS B) ASSS C) DISS D) CGA | C) DISS |
| When used to control the flow of medical gases to a patient, how is a Thorpe tube classified? | variable-orifice, constant-pressure flowmeter device |
| Specific clinical objectives of oxygen (O2) therapy include which of the following? I. Decrease the symptoms caused by chronic hypoxemia II. Decrease the workload hypoxemia imposes on the heart and lungs III. Correct documented arterial hypoxemia | I. Decrease the symptoms caused by chronic hypoxemia II. Decrease the workload hypoxemia imposes on the heart and lungs III. Correct documented arterial hypoxemia |
| What can properly applied O2 therapy decrease? I. Ventilatory demand II. Work of breathing III. Cardiac output | I. Ventilatory demand II. Work of breathing III. Cardiac outp |
