CER CER - Certified Endoscope Reprocessor Chemical Disinfectants and Germicides Questions and Answers 1

Question 1

What does MEC stand for in the context of high-level disinfectant testing?

Accepted Answer

Minimum Effective Concentration

Answer

MEC stands for Minimum Effective Concentration, the lowest concentration at which a disinfectant remains effective against target organisms.

Question 2

Which test strip is used to verify that glutaraldehyde solution maintains its minimum effective concentration?

Accepted Answer

MEC test strips

Answer

MEC test strips are specifically designed to confirm that glutaraldehyde concentration has not fallen below the level required for high-level disinfection.

Question 3

What is the typical reuse life of activated glutaraldehyde 2.4% solution when used for high-level disinfection?

Accepted Answer

14 days

Answer

Most activated glutaraldehyde 2.4% formulations are approved for reuse up to 14 days, provided MEC testing confirms adequate concentration.

Question 4

Ortho-phthalaldehyde (OPA) provides which primary advantage over glutaraldehyde for endoscope HLD?

Accepted Answer

Less irritating vapors and no activation required

Answer

OPA does not require activation, produces less irritating vapors, and does not require special ventilation requirements like glutaraldehyde.

Question 5

Which OSHA regulation establishes the permissible exposure limit (PEL) for glutaraldehyde in healthcare settings?

Accepted Answer

OSHA's Hazard Communication Standard (HCS)

Answer

OSHA's Hazard Communication Standard requires employers to inform workers of glutaraldehyde hazards, and NIOSH has set a recommended exposure limit of 0.2 ppm ceiling.
