CER CER - Certified Endoscope Reprocessor Chemical Disinfectants and Germicides Questions and Answers 5

Question 1

A staff member accidentally splashes OPA solution into their eyes. Which immediate first-aid action is correct?

Accepted Answer

Flush immediately with large amounts of water for at least 20 minutes

Answer

Immediate and prolonged water flushing (minimum 20 minutes) is the standard first-aid response for OPA or any chemical splash to the eyes.

Question 2

What is the primary reason that glutaraldehyde solution must be covered when not in use during the reprocessing process?

Accepted Answer

To limit vapor release and reduce staff exposure to irritating fumes

Answer

Covering glutaraldehyde containers limits the release of irritating and potentially harmful vapors into the work environment, protecting staff from respiratory and mucous membrane irritation.

Question 3

An endoscope labeled by the manufacturer as compatible only with 2.4% alkaline glutaraldehyde is submitted for reprocessing. The facility only has OPA available. What should the technician do?

Accepted Answer

Consult the scope manufacturer's IFU before using any alternative chemical disinfectant

Answer

The endoscope manufacturer's Instructions for Use (IFU) must be followed for chemical compatibility; using an unapproved chemical can damage the scope and void warranties.

Question 4

Which of the following best describes the mode of action of OPA as a high-level disinfectant?

Accepted Answer

Alkylation of cellular proteins and nucleic acids, impairing microbial replication

Answer

OPA is an aromatic dialdehyde that achieves germicidal activity primarily through alkylation, cross-linking the proteins and nucleic acids of microorganisms.

Question 5

A new glutaraldehyde product states a reuse life of 28 days after activation. Which best practice should guide the reprocessor?

Accepted Answer

Test the solution's MEC daily and discard it when it falls below MEC or at 28 days, whichever comes first

Answer

MEC testing must be performed before each use (or per policy), and the solution must be discarded when it either fails MEC testing or reaches the manufacturer's maximum reuse life, whichever occurs first.
