CRCST Quality Assurance 5

Question 1

What is the most appropriate action when a sterilizer's mechanical printout shows the cycle temperature was 2°F below the validated minimum for the full exposure time?

Accepted Answer

Quarantine the load and report the out-of-parameter cycle

Answer

Any cycle that fails to achieve validated parameters is an out-of-parameter cycle; the load must be quarantined, the event documented, and a root cause investigation initiated.

Question 2

Which quality assurance tool is best used to display the frequency distribution of defects or failures to identify the most common causes?

Accepted Answer

Pareto chart

Answer

A Pareto chart ranks problems by frequency and highlights the 'vital few' causes responsible for the majority of defects, helping prioritize improvement efforts.

Question 3

What does 'event-related sterility' mean for a packaged sterile item?

Accepted Answer

Sterility is maintained indefinitely unless the package is compromised

Answer

Event-related sterility means a properly packaged item remains sterile indefinitely as long as the packaging integrity is maintained and no compromising event occurs.

Question 4

Which statement best describes the purpose of a quality management system (QMS) in a central service department?

Accepted Answer

To provide a framework ensuring consistent processes, accountability, and continuous improvement

Answer

A QMS provides a structured framework for documenting processes, ensuring accountability, monitoring outcomes, and driving continuous improvement in CS operations.

Question 5

When must a biological indicator be run in a sterilizer that processes implantable devices?

Accepted Answer

With every load containing implantable devices

Answer

AAMI ST79 and AORN guidelines require a BI with every load containing implantable devices, and results must be reviewed before implants are released for use.
