CER High-Level Disinfection Processes Questions and Answers 5

Question 1

A facility switches from glutaraldehyde to OPA. Which patient population requires special precaution with OPA due to risk of hypersensitivity?

Accepted Answer

Patients with bladder cancer treated with BCG therapy

Answer

OPA has been associated with severe anaphylactic reactions in bladder cancer patients who have received multiple BCG (bacillus Calmette-Guérin) instillation treatments.

Question 2

What is the maximum reuse life (in days) typically stated on glutaraldehyde product labels for a 2.4–2.65% activated solution?

Accepted Answer

14 days

Answer

Most activated glutaraldehyde products (e.g., Cidex) are labeled for a maximum of 14 days reuse life, provided MEC testing confirms adequate concentration throughout.

Question 3

Which personal protective equipment (PPE) is specifically required when handling glutaraldehyde or OPA?

Accepted Answer

Chemical-resistant gloves, eye protection, and liquid-resistant gown

Answer

Chemical-resistant gloves (nitrile or thicker), splash-proof eye protection, and a liquid-resistant gown are required when handling HLD chemicals to prevent skin, eye, and respiratory exposure.

Question 4

If an automated endoscope reprocessor (AER) cycle is interrupted before completion, what must be done?

Accepted Answer

The scope must be manually reprocessed from the beginning

Answer

An incomplete AER cycle invalidates the reprocessing; the entire manual or automated process must restart from the cleaning step to ensure patient safety.

Question 5

Which of the following is the correct order for manual high-level disinfection of a flexible endoscope?

Accepted Answer

Precleaning → leak test → manual cleaning → HLD soak → rinse → dry → store

Answer

The validated sequence begins with point-of-use precleaning, followed by leak testing, manual cleaning, HLD soak, rinsing, drying, and then proper storage.
