SPD - Sterile Processing Department Technician Sterilization Methods and Monitoring Questions and Answers

Question 1

An implantable device has just been processed through a steam sterilization cycle.
According to AAMI ST79 standards, what is the most critical requirement before this implant can be released for patient use?

Accepted Answer

The load must be quarantined until the biological indicator (BI) result is confirmed as negative.

Answer

The external chemical indicator on the package must show a complete color change.

Answer

The cycle printout must be verified and signed by the department supervisor.

Answer

An internal chemical indicator from a non-implant package in the same load must show a pass result.

Question 2

A sterile processing department must sterilize a set of delicate, heat-sensitive instruments. Ethylene Oxide (EtO) is chosen as the appropriate method. Which of the following is a critical post-cycle step unique to EtO sterilization?

Accepted Answer

A mandatory aeration period to remove residual toxic gas.

Answer

Rapid cooling of the items to room temperature.

Answer

Rinsing the items with sterile, deionized water.

Answer

Immediate packaging in a secondary dust cover.

Question 3

Which of the following is the primary purpose of performing a daily Bowie-Dick test on a dynamic-air-removal steam sterilizer?

Accepted Answer

To check the efficacy of the air removal system and detect air leaks.

Answer

To confirm the sterility of the items within the load.

Answer

To verify the sterilizer has reached the correct temperature.

Answer

To challenge the cycle with a high concentration of bacterial spores.

Question 4

A Class 5 chemical integrating indicator is placed inside a wrapped instrument tray during a steam sterilization cycle. What does a successful "pass" result from this specific indicator signify?

Accepted Answer

The sterilant penetrated the package and all critical parameters (time, temperature, and saturated steam) were met.

Answer

The items inside the package are guaranteed to be sterile.

Answer

The package was exposed to elevated temperatures, but not necessarily steam.

Answer

The sterilizer's vacuum and pressure systems are functioning correctly.

Question 5

The microorganism used within biological indicators to test the efficacy of steam sterilization and hydrogen peroxide gas plasma sterilization is:

Accepted Answer

Geobacillus stearothermophilus

Answer

Bacillus atrophaeus

Answer

Clostridium difficile

Answer

Staphylococcus aureus

Question 6

When an instrument is processed using an immediate-use steam sterilization (IUSS) cycle, which of the following is true regarding process monitoring?

Accepted Answer

The same physical and chemical monitoring protocols as terminal sterilization must be followed and documented.

Answer

Monitoring is not required because the item is for emergency use.

Answer

Only an external chemical indicator is needed due to the rapid turnaround.

Answer

Biological monitoring can be skipped if the cycle is less than five minutes.
