What is the primary purpose of performing a leak test on a flexible endoscope before reprocessing?
Answer: To detect damage to the sheath or internal channels that could allow fluid ingress
Leak testing detects damage to the endoscope's sheath or channels that could allow reprocessing fluids to penetrate and cause irreparable internal damage.
Which type of brush is recommended for cleaning endoscope channels?
Answer: A manufacturer-validated, single-use brush sized to the specific channel diameter
Single-use, manufacturer-validated brushes of the correct diameter ensure effective cleaning without damaging channel walls or causing cross-contamination.
What does 'functional testing' of an endoscope following reprocessing include?
Answer: Checking controls, channels, optics, and angulation to confirm readiness for use
Functional testing verifies all mechanical and optical components work properly before returning the scope to clinical use.
When should a flexible endoscope undergo preventive maintenance by a qualified repair technician?
Answer: According to the manufacturer's recommended schedule and after any suspected damage
Scheduled preventive maintenance and post-incident inspections ensure optimal performance and early detection of defects before patient harm occurs.
What is the correct action if an endoscope fails a leak test?
Answer: Remove from service, label as defective, and send for repair before any further patient use
A failed leak test indicates a compromised scope that must be removed from service immediately to prevent patient harm and further internal damage.
What is the minimum required action after every endoscope procedure before transport to the reprocessing area?
Answer: Point-of-use cleaning including wiping the exterior and flushing channels with enzymatic solution
Point-of-use cleaning removes gross soil immediately after use, preventing biofilm formation and facilitating subsequent reprocessing steps.
Which factor most significantly impacts the efficacy of high-level disinfection (HLD)?
Answer: Adequate manual cleaning performed prior to HLD
Thorough manual cleaning before HLD is critical because residual organic material shields microorganisms from disinfectant action.
