Question 1

What is the minimum recommended water quality for use in the final rinse cycle of automated washers in sterile processing?

Accepted Answer

Deionized or purified water

Answer

Deionized or purified water is recommended for final rinse cycles to prevent mineral deposits and residue that could interfere with sterilization or cause patient harm.

Question 2

A sterile package is found with a small tear in the outer wrap. What is the correct action?

Accepted Answer

Consider the package non-sterile and reprocess the item

Answer

Any compromise to packaging integrity renders the item non-sterile; the item must be removed from service and reprocessed.

Question 3

Which sterilization method is most appropriate for heat-sensitive, moisture-sensitive devices such as certain flexible endoscopes?

Accepted Answer

Ethylene oxide (EO) gas sterilization

Answer

Ethylene oxide sterilization is performed at low temperatures and is suitable for heat- and moisture-sensitive items like flexible endoscopes.

Question 4

What does 'event-related sterility' mean?

Accepted Answer

Sterility is maintained until the package is opened or its integrity is compromised

Answer

Event-related sterility means that a properly packaged, intact item remains sterile until an event occurs that compromises the package, not simply based on a date.

Question 5

What is the purpose of a chemical integrator (Class 5) used inside a sterilization tray?

Accepted Answer

To react to all critical sterilization parameters and provide a pass/fail result

Answer

Class 5 chemical integrators respond to all critical parameters (time, temperature, steam) and provide a reliable internal indicator of sterilization conditions within the load.
