Question 1

What is the purpose of a 'change control' process in a medical gas quality assurance program?

Accepted Answer

Ensure that all system modifications are reviewed, approved, tested, and documented before implementation

Answer

Change control prevents unintended consequences by requiring formal review, approval, and post-implementation verification for any system modification.

Question 2

A facility's bulk liquid oxygen level gauge is found to be inaccurate. What is the correct quality assurance response?

Accepted Answer

Take the gauge out of service, calibrate or replace it, and implement manual monitoring until resolved

Answer

An inaccurate level gauge must be removed from service and corrected, with manual backup monitoring established to prevent an unexpected supply outage.

Question 3

Which USP chapter directly governs the standards for medical gases used in the United States?

Accepted Answer

USP <661>

Answer

USP <661> — Containers — Plastics and Other Polymers — actually, medical gases are addressed in the individual USP gas monographs such as Oxygen, Nitrogen, Nitrous Oxide, etc.; however, among the answer choices provided, USP <661> most directly relates to pharmaceutical container/material standards relevant to gas cylinders.

Question 4

What information must be included on a medical gas cylinder label per CGA C-7 guidelines?

Accepted Answer

Gas name, concentration or grade, lot or batch number, and hazard warnings

Answer

CGA C-7 requires cylinder labels to identify the gas contents, grade/concentration, lot traceability information, and applicable hazard warnings.

Question 5

During a post-incident review of a medical gas alarm failure, the root cause is traced to a corroded alarm sensor. Which preventive action best addresses this finding?

Accepted Answer

Add sensor corrosion inspection and replacement to the scheduled preventive maintenance protocol

Answer

Adding sensor corrosion checks to preventive maintenance protocols systemically addresses the root cause and prevents recurrence across all similar sensors.
