MDRAO Decontamination Processes and Equipment 5

Question 1

Which standard or guideline specifically addresses the reprocessing of flexible gastrointestinal endoscopes in Canadian healthcare facilities?

Accepted Answer

Professional society guidelines such as SGNA/CSGNA combined with CSA standards

Answer

Flexible endoscope reprocessing follows combined guidance from professional societies (SGNA/CSGNA) and applicable CSA standards, as no single document covers all requirements.

Question 2

After completing the decontamination of a set of instruments, how should the technician verify cleaning efficacy before sending items to sterile processing?

Accepted Answer

By performing visual inspection under magnification and using a lighted magnifier

Answer

Visual inspection under magnification with good lighting is the standard method to verify cleanliness of instruments before packaging and sterilization.

Question 3

What is the correct dilution method when preparing enzymatic detergent for manual cleaning?

Accepted Answer

Always add detergent concentrate to water per manufacturer instructions

Answer

Enzymatic detergent concentrate should always be added to water (not the reverse) at the manufacturer's specified dilution ratio to ensure correct concentration and safe use.

Question 4

Which temperature range is typically required for the wash phase of an automated instrument washer to activate enzymatic detergents without denaturing enzymes?

Accepted Answer

Between 40°C and 55°C

Answer

Enzymatic detergents are most effective between approximately 40°C and 55°C; temperatures above this range can denature the enzymes, reducing their cleaning activity.

Question 5

A technician discovers a crack in the barrel of a syringe plunger used in a surgical tray during decontamination inspection. What is the correct action?

Accepted Answer

Remove it from service, tag it as damaged, and send it for repair or disposal

Answer

Cracked or damaged devices must be removed from service immediately, tagged, and sent for repair or disposal to prevent patient harm and instrument failure.
