1. The primary purpose of a medical gas system is to
A. Provide electrical grounding
B. Supply medical gases to patient care areas
C. Generate steam for heating
D. Monitor air quality
B. Supply medical gases to patient care areas
Rationale: The medical gas system’s main function is to deliver regulated gases
to clinical locations.
2. The color code for oxygen pipeline in the United States is
A. Black
B. Brown
C. Green
D. Orange
C. Green
Rationale: Oxygen is coded green per NFPA/CGMP to distinguish it from other
gases.
3. Which standard addresses medical gas and vacuum systems?
A. NFPA 99
B. OSHA 1910
C. ASME VIII
,D. ANSI A117.1
A. NFPA 99
Rationale: NFPA 99 outlines health care facilities’ criteria including medical gas
systems.
4. A manifold in a medical gas system is used to
A. Store electricity
B. Act as a central gas source connection
C. Control humidity
D. Filter contaminants
B. Act as a central gas source connection
Rationale: A manifold ties multiple cylinder banks together as a unified supply.
5. The alarm for a medical gas system should activate when pressure
A. Is too high or too low
B. Exceeds 1,000 PSI
C. Is stable
D. Changes rapidly
A. Is too high or too low
Rationale: Medical gas alarms indicate abnormal pressures outside set limits.
6. Medical air must be free of
A. Water vapor
B. Bacteria and contaminants
C. Ambient noise
D. Light
B. Bacteria and contaminants
Rationale: Clean air supply is required for patient safety.
7. The pipeline material commonly used for oxygen systems is
A. PVC
B. Copper
C. Aluminum
, D. Steel rebar
B. Copper
Rationale: Copper is corrosion‐resistant and suitable for medical gas
distribution.
8. Medical vacuum systems remove
A. Heat from buildings
B. Gases from patient procedures
C. Contaminants from water
D. Radio waves
B. Gases from patient procedures
Rationale: The vacuum system evacuates waste gases and secretions.
9. Which regulator type is installed at cylinder banks?
A. Pressure reducing regulator
B. Hydraulic pump
C. Thermostat
D. Flow switch
A. Pressure reducing regulator
Rationale: Regulators control gas pressure to safe delivery levels.
10. The purpose of a check valve is to
A. Prevent backflow
B. Increase pressure
C. Filter particles
D. Measure flow rate
A. Prevent backflow
Rationale: Check valves ensure unidirectional gas flow.
11. Acetylene is not used in patient care because
A. It has an unpleasant odor
B. It is flammable
C. It corrodes pipes
