RMGA Quality Assurance 2 — Questions and Answers
Question 1: Which document must be obtained from a medical gas supplier to verify the purity of a bulk liquid oxygen delivery?
- Certificate of Analysis (CoA) (Correct answer)
- Material Safety Data Sheet only
- Delivery manifest
- Insurance certificate
Correct answer: Certificate of Analysis (CoA)
A Certificate of Analysis from the supplier verifies that the delivered medical gas meets USP purity specifications.
Question 2: Under NFPA 99, how frequently must bulk medical gas systems be inspected by qualified personnel?
- Daily visual checks with periodic formal inspections (Correct answer)
- Only when a problem is reported
- Annually by the state health department
- Every five years by a third-party auditor
Correct answer: Daily visual checks with periodic formal inspections
NFPA 99 requires routine visual checks and periodic formal inspections to ensure continuous safe operation of bulk systems.
Question 3: What is the primary purpose of a risk assessment in medical gas quality assurance programs?
- Identify hazards and prioritize corrective actions before incidents occur (Correct answer)
- Document past incidents for legal defense
- Satisfy accreditation paperwork requirements only
- Calculate the cost of gas purchases
Correct answer: Identify hazards and prioritize corrective actions before incidents occur
Risk assessment proactively identifies potential failure points and assigns priority to corrective measures to prevent patient harm.
Question 4: When performing a pressure drop test on a medical gas zone valve, what result indicates the valve is functioning properly?
- Downstream pressure drops to zero when the valve is closed (Correct answer)
- Upstream pressure drops when the valve is opened
- No pressure change occurs in either direction
- Pressure equalizes immediately across the valve
Correct answer: Downstream pressure drops to zero when the valve is closed
A properly functioning zone valve completely isolates downstream piping, causing downstream pressure to drop to zero when closed.
Question 5: Which of the following is a key element of a medical gas facility's quality management system documentation?
- Corrective and preventive action (CAPA) records (Correct answer)
- Employee vacation schedules
- Vendor advertising materials
- Annual revenue reports
Correct answer: Corrective and preventive action (CAPA) records
CAPA records demonstrate how the facility identifies deficiencies and systematically resolves and prevents their recurrence.
Question 6: A hospital discovers that a medical air compressor has been cross-connected with a nitrogen line. What is the immediate quality assurance response?
- Take the affected system out of service and notify clinical staff immediately (Correct answer)
- Continue operation while scheduling a repair for the next maintenance window
- Increase nitrogen purity testing frequency
- Document the issue and review at the next quarterly meeting
Correct answer: Take the affected system out of service and notify clinical staff immediately
A cross-connection is a critical patient safety hazard requiring immediate system shutdown and clinical notification to prevent patient harm.
Question 7: Under CGA guidelines, what must be verified on a medical gas cylinder before it is placed into service?
- Proper labeling, valve condition, and hydrostatic test date are all within limits (Correct answer)
- Cylinder color is correct for the facility's preferred supplier
- The cylinder was manufactured in the United States
- The cylinder has been in storage for less than one year
Correct answer: Proper labeling, valve condition, and hydrostatic test date are all within limits
CGA standards require verification of labeling accuracy, valve integrity, and a current hydrostatic test date before a cylinder enters service.
