Verify image quality
undefined
Which personal protective equipment is most appropriate during manual cleaning of a contaminated flexible endoscope?
Lead apron and dosimeter
Sterile surgical gown and sterile gloves only
Hair cover and shoe covers only
Fluid-resistant gown, eye/face protection, and appropriate gloves
undefined
High-level disinfection (HLD) is intended to destroy
Vegetative bacteria, mycobacteria, most viruses, and some fungi
All forms of microbial life including spores
Microbes visible to the naked eye
Only gram-negative bacteria
undefined
Bedside pre-cleaning of a flexible endoscope should be performed
Immediately after the procedure, following the endoscope IFU
Only by the manufacturer representative
Only if visible soil is present
After transport to the storage cabinet
undefined
During manual cleaning, the correct sequence generally includes
Soaking in enzymatic detergent, thorough brushing and flushing of all channels, then rinsing per IFU
Rinsing, drying, disinfecting, then brushing
Wiping exterior only, then storing
Sterilizing, then brushing with tap water
undefined
True or False: Leak testing should be performed prior to immersion in fluids during the cleaning process.
True
False
undefined
Which statement best describes biofilm risk in endoscope channels?
Biofilm is beneficial for lubrication
Biofilm cannot form on medical devices
Delays in cleaning can promote biofilm formation that is harder to remove
Biofilm is removed by air drying alone
undefined
When preparing enzymatic detergent for manual cleaning, the CER should
Estimate concentration by color
Double the concentration for faster results
Mix to manufacturer-specified concentration and temperature using measured water quality
Use cold water only
undefined
True or False: If the MEC test strip passes, contact time and temperature are no longer critical.
False
True
undefined
Which action is appropriate if an endoscope fails the leak test?
Disinfect it twice to compensate
Use it only for short procedures
Remove from service and send for evaluation/repair per policy
Proceed with manual cleaning but avoid immersion
undefined
True or False: If an endoscope is new from the manufacturer, it may be used on a patient without reprocessing.
False
True
undefined
What is the best practice for test strip management for HLD MEC testing?
Use until the color no longer changes
Dry strips before use for accuracy
Follow expiration date, store per IFU, perform quality control as directed, and note open-bottle dating
Cut strips in half to save cost
undefined
True or False: The reuse life of a high-level disinfectant can be extended if the solution appears clear.
True
False
undefined
Which statement about water quality management during reprocessing is correct?
Any water is acceptable if filtered once a year
Water quality requirements are defined by device and chemical IFU and facility policies
Only sterile water may be used for all steps
Hot tap water always meets critical water standards
undefined
Which step best minimizes recontamination risk after final rinse?
Using aseptic connection to drying equipment and storing in a clean, ventilated cabinet designed for endoscopes
Coiling tightly in a drawer
Leaving valves installed to seal channels
Placing the wet scope on a towel
undefined
True or False: Only visible soil needs to be removed before HLD because disinfectants dissolve dried protein soils.
True
False
undefined
For bronchoscopes used in immunocompromised patients, which practice aligns with many current guidelines when feasible?
High-level disinfection is always preferred over sterilization
Cold water rinsing only
Sterilization is preferred when device compatibility and resources allow
No drying is necessary
undefined
True or False: The CER may deviate from the endoscope IFU if a more convenient method seems equivalent.
False
True
undefined
When calculating chemical disinfectant change frequency, the CER should base decisions on
Manufacturer reuse life limits, MEC test results, and facility policy
Days of the week
Color of the solution
Operator preference
undefined
0

Cheat Sheet

  1. Immediate Pre-Cleaning -

    Always begin endoscope processing within one minute of use by wiping the exterior, flushing all channels with enzymatic detergent, and keeping ports open. This "soak and flush" step prevents soil from drying and aids later cleaning steps (CDC, 2021). Remember the phrase "Flush Fast, Fail Less" as a quick reminder to act immediately.

  2. Manual Cleaning with Enzymatic Detergents -

    Use a soft-bristled brush and an approved enzymatic detergent to scrub channels and external surfaces for at least two minutes, ensuring bioburden is fully dissolved (AAMI ST91). Proper agitation and enzymatic action break down proteins, making subsequent disinfection more effective. Think "Brush, Rinse, Inspect" to stay consistent.

  3. Leak Testing and Channel Integrity -

    Perform a manual or automated leak test before high-level disinfection to detect channel breaches and prevent fluid intrusion into internal components (FDA guidelines). A simple mnemonic is "LEAK = Look, Examine, Air-pressurize, Keep watch." Maintaining integrity preserves the endoscope's lifespan and ensures patient safety.

  4. High-Level Disinfection Parameters -

    Select an EPA-registered disinfectant such as glutaraldehyde, ortho-phthalaldehyde, or peracetic acid and strictly adhere to manufacturer-specified temperature and contact time (e.g., 2% glutaraldehyde at 20°C for 20 minutes). Validate each cycle with chemical indicators placed in the distal tip. Remember "Time + Temp = Triumph" to ensure complete microbial kill.

  5. Rinsing, Drying, and Storage -

    Thoroughly rinse channels with sterile or filtered water, flush with 70 - 90% alcohol, and apply forced air to remove residual moisture (AORN Perioperative Standards). Hang endoscopes vertically in a well-ventilated cabinet to prevent biofilm formation. Use a tracking log with biological indicators to document quality control and traceability.
