CIS Decontamination and Cleaning Processes Questions and Answers 3

Question 1

What is the purpose of a washer-disinfector in the decontamination process?

Accepted Answer

To automate cleaning and provide thermal disinfection

Answer

A washer-disinfector automates the cleaning cycle and provides thermal disinfection by exposing instruments to hot water during the final rinse, reducing bioburden to safe handling levels.

Question 2

Why should instruments with lumens receive special attention during the cleaning process?

Accepted Answer

Soil and bioburden can become trapped inside narrow channels

Answer

Instruments with lumens require special attention because soil and bioburden can become trapped inside the narrow passages, where standard cleaning methods may not reach effectively.

Question 3

What is the significance of the Spaulding Classification system in instrument decontamination?

Accepted Answer

It categorizes items as critical, semi-critical, or non-critical based on infection risk

Question 4

What is the recommended action if an instrument falls to the floor during a surgical procedure?

Accepted Answer

Remove it from the sterile field and send it for complete reprocessing

Answer

Any instrument that contacts the floor is considered contaminated and must be removed from the sterile field and sent through the complete reprocessing cycle.

Question 5

What is the purpose of performing a protein residual test on cleaned instruments?

Accepted Answer

To detect remaining organic soil that indicates inadequate cleaning

Answer

Protein residual tests detect remaining organic matter on instrument surfaces after cleaning, serving as a quality control measure to verify cleaning effectiveness.
