(CRCST) Flashcards

Which document from a device manufacturer provides critical reprocessing instructions that CS technicians must follow?

Answer: The manufacturer's Instructions for Use (IFU)

Manufacturers' Instructions for Use (IFUs) provide legally validated, device-specific reprocessing instructions that must be followed to ensure safety and device integrity.

What is the purpose of a sterilization load control number (lot control number)?

Answer: To enable rapid identification and recall of items from a specific sterilization cycle

Lot control numbers link sterile items to a specific sterilizer cycle, enabling targeted recall if a sterilization failure is discovered.

Which condition would make a rigid sterilization container unacceptable for use?

Answer: Container has visible cracks, a damaged filter, or a missing locking mechanism

Cracks, damaged filters, or non-functioning locking mechanisms compromise the barrier integrity of a rigid container, rendering it unacceptable for sterilization.

What is the primary function of enzymatic detergents used in instrument cleaning?

Answer: To break down organic soil such as blood, protein, and fat through enzyme activity

Enzymatic detergents contain protease, lipase, and amylase enzymes that chemically break down organic matter, improving cleaning efficacy particularly in lumens and hinges.

When using a flash (immediate-use) steam sterilization cycle, what is a key limitation compared to terminal sterilization?

Answer: Items sterilized by flash cannot be stored and must be used immediately

Immediate-use steam sterilization (IUSS/flash) is intended for emergency use only; items cannot be packaged for storage and must be transported aseptically to the point of use immediately.

Which practice is required before using any powered surgical instrument that has been reprocessed?

Answer: Testing the instrument for proper function before returning it to service

Powered instruments must be functionally tested after reprocessing to confirm they operate correctly and safely before being used on a patient.

According to AAMI ST79, how often should biological indicators be used to monitor gravity displacement steam sterilizers?

Answer: At least weekly, and with every load containing implantable devices

AAMI ST79 recommends routine BI monitoring at least weekly for gravity sterilizers and with every load containing implantable devices, with results reviewed before implant release.
