CMDRT - Certified Medical Device Reprocessing Technician Decontamination Processes Questions and Answers 2

Question 1

What is the primary purpose of enzymatic detergent in the decontamination process?

Accepted Answer

To break down organic soil such as blood and tissue

Answer

Enzymatic detergents contain specific enzymes (proteases, lipases, amylases) that break down organic matter like blood, tissue, and body fluids on instruments before further cleaning steps.

Question 2

According to CSA standards, what is the recommended water temperature range for pre-soaking instruments in enzymatic solution?

Accepted Answer

Lukewarm water between 20°C and 43°C

Answer

CSA standards recommend lukewarm water (20°C to 43°C) for enzymatic solutions because temperatures above 43°C can denature the enzymes, reducing their effectiveness, while very cold water slows enzyme activity.

Question 3

What is the correct sequence of steps in the decontamination workflow?

Accepted Answer

Pre-cleaning at point of use → Transport → Cleaning → Rinsing → Disinfection/Sterilization

Answer

The standard decontamination workflow follows a logical progression: pre-cleaning at point of use to prevent soil from drying, safe transport to the reprocessing area, thorough cleaning, rinsing, and then disinfection or sterilization.

Question 4

What type of water should be used for the final rinse of instruments after cleaning?

Accepted Answer

Distilled or treated water meeting CSA specifications

Answer

The final rinse should use distilled, deionized, or reverse-osmosis treated water to prevent mineral deposits (spotting) on instruments and to avoid introducing contaminants that may be present in tap water.

Question 5

Why must instruments with lumens receive special attention during decontamination?

Accepted Answer

Soil and biofilm can accumulate inside narrow channels where standard cleaning cannot reach

Answer

Lumened instruments have narrow internal channels where blood, tissue, and biofilm can accumulate and are difficult to reach with standard cleaning methods. They require specific brushing, flushing, and sometimes ultrasonic cleaning to ensure adequate decontamination.
