Scope and Equipment Reprocessing Flashcards

During reprocessing, a GI nurse notes a continuous stream of bubbles from the bending section during the leak test. What is the most appropriate action?

Answer: Stop reprocessing, follow the manufacturer's instructions, and remove the scope from service for repair

A failed leak test means fluid can enter the scope and damage it, so reprocessing stops and the scope goes for repair per the manufacturer's instructions.

At which point in the reprocessing sequence should the leak test be performed?

Answer: After bedside precleaning and before manual cleaning

Leak testing comes before manual cleaning so damage is found before the scope is immersed in detergent.

Which high-level disinfectant has been linked to anaphylaxis in bladder cancer patients after repeated cystoscopy and can stain skin gray?

Answer: Ortho-phthalaldehyde (OPA)

OPA residue has been linked to anaphylaxis after repeated urologic procedures, and OPA stains proteins, including skin, gray.

Which of the following is NOT one of the FDA's supplemental measures for duodenoscope reprocessing?

Answer: Soaking in enzymatic detergent for 60 minutes in place of manual brushing

The FDA lists culturing, EtO sterilization, liquid chemical sterilant, and double HLD; nothing replaces manual brushing.

Why is thorough manual cleaning essential before high-level disinfection of an endoscope?

Answer: Organic debris and biofilm keep the disinfectant from reaching microorganisms

Leftover organic material and biofilm protect microbes from disinfectants, so HLD fails without good cleaning.

The minimum effective concentration (MEC) test strip for a reusable high-level disinfectant shows a fail result. What should the nurse do?

Answer: Discard the solution, replace it with fresh solution, and document the result

Solution below MEC cannot reliably achieve HLD and must be replaced, with the result documented.

Under the Spaulding classification, reusable biopsy forceps that break the mucosal barrier are classified as:

Answer: Critical items requiring sterilization

Devices that enter sterile tissue or penetrate mucosa are critical and must be sterilized.
