Instrument Processing Flashcards

During inspection of instruments before packaging, which quality check should be performed on scissors?

Answer: Test cutting ability by cutting through a test material appropriate for that instrument

Scissors should be tested by cutting appropriate test material (e.g., gauze or test paper) to verify proper alignment and cutting function before sterilization.

Ethylene oxide (EO) sterilization requires a mandatory aeration period after the cycle primarily to:

Answer: Dissipate toxic EO residues from items before they are safe for patient use

EO is toxic to humans, and aeration is required to allow EO residues to off-gas from materials to safe levels before the items are used on patients.

Which of the following is a key principle when loading a steam sterilizer to ensure effective sterilization?

Answer: Position items to allow steam circulation and condensate drainage

Proper loading requires adequate space for steam circulation and positioning items so condensate drains away, preventing wet packs and ensuring steam contact.

A flash sterilization (Immediate Use Steam Sterilization/IUSS) cycle is most appropriately used when:

Answer: An instrument is dropped in the OR and is urgently needed with no sterile replacement available

IUSS is intended for urgent, unplanned situations where a dropped or contaminated instrument is urgently needed and no sterile replacement is available.

What is the primary hazard of inadequate rinsing of enzymatic detergent from instruments before sterilization?

Answer: Residual detergent can cause patient tissue irritation or toxic reactions

Residual enzymatic detergent on instruments can cause toxic or adverse reactions in patients when the instruments contact tissue during procedures.

Which organization publishes the ANSI/AAMI standards that govern sterilization practices in healthcare facilities in the United States?

Answer: Association for the Advancement of Medical Instrumentation (AAMI)

AAMI publishes ANSI/AAMI standards (such as ST79) that provide comprehensive guidance on sterilization practices for healthcare sterile processing departments.

When a loaner instrument set arrives from a vendor on the day of surgery, the sterile processing technician should:

Answer: Decontaminate, inspect, package, and sterilize the set according to facility policy before use

Loaner instruments must be fully decontaminated and processed according to facility policy regardless of vendor-supplied documentation, as they may have been used at other facilities.
