Decontamination and Manual Cleaning Flashcards

What is the significance of the 'leak test' in relation to manual cleaning?

Answer: It detects damage to the scope's protective sheath before immersion in cleaning solutions

The leak test identifies breaches in the endoscope's outer sheath before immersion, preventing cleaning fluids from entering internal components and causing irreparable damage.

Which of the following best describes a 'multi-enzyme' cleaner used in endoscope reprocessing?

Answer: A cleaner containing multiple enzymes such as protease, lipase, and amylase to break down various organic soils

Multi-enzyme cleaners contain several enzymes targeting different organic substrates—proteins, fats, and carbohydrates—providing broader soil removal capability.

After manual brushing, what is the next step in the manual cleaning process before high-level disinfection?

Answer: Thoroughly rinse all channels and surfaces with water to remove detergent and loosened soil

Thorough rinsing removes detergent residue and loosened soil, preventing cleaning solution interference with the disinfectant and potential patient harm from residues.

What is the recommended practice if an endoscope's channel cannot be effectively brushed due to an angulation or design feature?

Answer: Use additional flushing with enzymatic solution and follow manufacturer-specific cleaning instructions for that model

Channels that cannot be brushed must receive additional flushing per manufacturer guidance, and any design-specific cleaning accessories provided should be used.

Why is it important to use only detergents that are compatible with the endoscope manufacturer's specifications?

Answer: Incompatible detergents can damage seals, coatings, and internal components of the endoscope

Incompatible cleaning agents can degrade endoscope materials, compromising scope integrity, shortening lifespan, and potentially harming patients.

During manual cleaning, how should elevator channels found on duodenoscopes be treated?

Answer: They require special brushes and detailed cleaning per manufacturer IFU due to their complex design

Duodenoscope elevator mechanisms have complex recessed areas that harbor bioburden and require specific cleaning tools and detailed manual cleaning steps per manufacturer IFU.

What is the correct disposal method for enzymatic cleaning solution after it has been used to clean an endoscope?

Answer: Discard after each use as enzymatic solutions are single-use

Enzymatic cleaning solutions are single-use and must be discarded after each endoscope cleaning because reused solution becomes saturated with organic material and loses effectiveness.
