HSPA CER Certified Endoscope Reprocessor

What is the FIRST step in endoscope reprocessing after a procedure is completed?

• AImmerse the endoscope in enzymatic detergent
• BPerform a leak test
• CWipe the insertion tube and flush channels at the point of use
• DPlace the endoscope in an automated endoscope reprocessor

Why is leak testing performed before manual cleaning of a flexible endoscope?

• ATo verify the endoscope is free of biofilm
• BTo detect damage that could allow fluid ingress into the internal components during immer…
• CTo confirm the endoscope has been properly precleaned at the point of use
• DTo ensure the enzymatic detergent is at the correct concentration

During manual cleaning, what is the primary purpose of using an enzymatic detergent?

• ATo achieve high-level disinfection of the endoscope surfaces
• BTo break down organic material such as blood, tissue, and mucus within channels
• CTo sterilize the biopsy channel
• DTo neutralize chemical disinfectant residue from previous cycles

According to the Spaulding classification system, flexible endoscopes that contact mucous membranes are classified as:

• ACritical devices
• BSemi-critical devices
• CNon-critical devices
• DIntermediate devices

What is the minimum level of reprocessing required for a flexible endoscope used in a colonoscopy?

• AIntermediate-level disinfection
• BLow-level disinfection
• CHigh-level disinfection
• DSterilization

Which component of a flexible endoscope allows the physician to obtain tissue samples during a procedure?

• AAir/water channel
• BSuction channel
• CBiopsy/instrument channel
• DLight guide bundle

What is the purpose of the air/water channel in a flexible endoscope?

• ATo deliver enzymatic detergent during reprocessing
• BTo insufflate the body cavity with air and irrigate the lens with water
• CTo aspirate fluids from the procedural field
• DTo pass electrical cautery instruments

Which personal protective equipment (PPE) is required when manually cleaning endoscopes in the decontamination area?

• AGloves only
• BGloves and a surgical mask
• CFluid-resistant gown, gloves, face shield or goggles with mask, and hair cover
• DSterile gown and sterile gloves

What does high-level disinfection (HLD) accomplish?

• AKills all microorganisms including high numbers of bacterial spores
• BKills all microorganisms except high numbers of bacterial spores
• CKills only vegetative bacteria and some viruses
• DRemoves all visible soil from instrument surfaces

In a properly designed endoscope reprocessing area, how should workflow be organized?

• AAll reprocessing steps should occur in the same room to improve efficiency
• BDirty-to-clean workflow with physical separation between decontamination and clean areas
• CClean-to-dirty workflow to ensure endoscopes start in the cleanest area
• DWorkflow direction does not matter as long as PPE is worn

What is biofilm and why is it significant in endoscope reprocessing?

• AA thin layer of lubricant that protects endoscope channels from wear
• BA community of microorganisms embedded in an extracellular matrix that is highly resistan…
• CA chemical residue left by high-level disinfectants on endoscope surfaces
• DA protective coating applied by the manufacturer to the endoscope insertion tube

What is the correct order of endoscope reprocessing steps after point-of-use precleaning?

• ALeak test → manual cleaning → rinse → HLD → rinse → dry
• BManual cleaning → leak test → HLD → rinse → dry
• CHLD → manual cleaning → leak test → rinse → dry
• DLeak test → HLD → manual cleaning → rinse → dry

When transporting a soiled endoscope from the procedure room to the reprocessing area, which of the following is required?

• AThe endoscope should be carried openly for quick access
• BThe endoscope should be placed in a closed, leak-proof transport container
• CThe endoscope should be wrapped in a sterile drape
• DThe endoscope should be placed in a storage cabinet until transport

What is the primary purpose of a tracking system in endoscope reprocessing?

• ATo monitor the location of staff members during shifts
• BTo link each endoscope to the patient, procedure, and reprocessing cycle for traceability
• CTo automatically adjust the concentration of disinfectant solutions
• DTo schedule preventive maintenance for facility HVAC systems

Which of the following is the MOST important reason for thorough drying of endoscopes after high-level disinfection?

• ATo prevent damage to the video chip
• BTo reduce the weight of the endoscope for storage
• CTo inhibit the growth of waterborne microorganisms such as Pseudomonas in residual moistu…
• DTo remove residual enzymatic detergent

A reprocessing technician notices that the minimum effective concentration (MEC) test strip shows the high-level disinfectant is below the required concentration. What should the technician do?

• AAdd more concentrated disinfectant to the solution and retest
• BDiscard the solution and replace it with fresh disinfectant
• CProceed with disinfection since the solution was recently prepared
• DIncrease the contact time to compensate for the lower concentration
