What endoscope channel is most frequently associated with reprocessing failures and infection transmission?
Answer: Elevator channel of duodenoscopes
The elevator channel of duodenoscopes has been most frequently associated with reprocessing failures due to its complex design.
What is the correct sequence of steps in manual endoscope reprocessing?
Answer: Pre-clean, leak test, manual clean, rinse, HLD, rinse, dry
The correct sequence ensures each step builds on the previous one to maximize reprocessing efficacy.
A biopsy channel brush emerges with frayed bristles. What action should be taken?
Answer: Discard immediately and inspect the scope channel for damage
A damaged brush must be discarded and the scope channel inspected for damage that may have caused the fraying.
What is the purpose of the alcohol flush step in endoscope reprocessing?
Answer: Facilitate drying by displacing residual water in channels
The 70% isopropyl alcohol flush displaces residual water and facilitates rapid drying.
How often should AERs be validated for proper function?
Answer: At installation, after maintenance/repair, and at regular intervals per manufacturer recommendations
AERs require validation at multiple points in their lifecycle, not just on a single schedule.
What water quality standard is required for the final rinse after high-level disinfection?
Answer: Sterile water, bacteria-free filtered water, or water meeting AAMI standards
The final rinse must use sterile or bacteria-free water to prevent recontamination.
