MDRAO Introduction 5

Question 1

Which area of the medical device reprocessing department (MDRD) is considered the 'cleanest' and must be physically separated from other zones?

Accepted Answer

Sterile storage area

Answer

The sterile storage area must be kept separate and maintained at the highest cleanliness standard to prevent contamination of processed items.

Question 2

What is the primary reason single-use devices (SUDs) should not be reprocessed unless following strict regulatory requirements?

Accepted Answer

The manufacturer validated them for one use only; reprocessing may compromise safety, sterility, and function

Answer

Manufacturers validate SUDs for a single use, and reprocessing may alter device integrity, leave residues, or fail to achieve sterility.

Question 3

What does 'event-related sterility' mean in medical device reprocessing?

Accepted Answer

Sterility is maintained until the package is damaged, wet, or opened — not based solely on a calendar date

Answer

Event-related sterility means the sterile barrier is maintained until a physical event (damage, moisture, opening) compromises the package.

Question 4

Which microorganism is considered the most resistant to sterilization and is commonly used in biological indicators for steam sterilization?

Accepted Answer

Geobacillus stearothermophilus

Answer

Geobacillus stearothermophilus spores are the most heat-resistant microorganisms and serve as the gold standard BI for steam sterilization.

Question 5

A reprocessing technician notices rust on a surgical instrument during inspection. What is the most appropriate action?

Accepted Answer

Remove the instrument from service and report it for evaluation or replacement

Answer

Rusted instruments are compromised and must be removed from service because rust can harbor microorganisms and the instrument may fail during use.
