Instrument Inspection Flashcards

What is the purpose of performing an ATP bioluminescence test on instruments?

Answer: To detect the presence of organic residue indicating inadequate cleaning

ATP testing provides rapid, objective verification that cleaning has removed organic material from instruments, serving as a quality assurance check before sterilization.

How should scissors be tested for proper cutting function during inspection?

Answer: By cutting through aluminum foil or thin test material from tip to pivot in a single smooth cut

Scissors should cut smoothly through thin material from tip to pivot point without catching, tearing, or requiring excessive force.

What should a technician look for when inspecting rigid endoscopes?

Answer: Clarity of optics, integrity of the light bundle, lens condition, and any dents or bends in the shaft

Rigid endoscopes require careful inspection of optical clarity, light transmission, lens integrity, and structural condition to ensure proper visualization during procedures.

Why is it important to inspect instruments for residual moisture before packaging?

Answer: Residual moisture can cause wet packs, promote corrosion, and compromise sterilization effectiveness

Residual moisture leads to wet packs (a sterilization failure), promotes rust and corrosion, and can harbor microorganisms that survive the sterilization process.

What is the recommended approach for inspecting power tools and pneumatic instruments?

Answer: Test operation, check all attachments, verify lubrication per manufacturer IFU, and inspect power cords or air hoses

Power tools require functional testing, attachment verification, manufacturer-specified lubrication, and inspection of all components that could affect performance or safety.

When should an instrument be removed from service for sharpening versus replacement?

Answer: Instruments with minor dulling can be professionally sharpened, but those with structural damage or repeated failures should be replaced

Minor dulling can be corrected through professional sharpening, but structural damage or repeated performance failures indicate the instrument has reached end of life.
