When evaluating implant loads after steam sterilization, what is required before the items can be released for use?
Answer: A passing BI result and quarantine until BI results are confirmed negative
Implants must be quarantined until BI results confirm a negative (passing) result; routine release without BI confirmation is not acceptable for implant loads.
A CS technician is evaluating a loaner instrument tray received from a vendor. What must be verified before these instruments are processed?
Answer: That manufacturer IFUs are available and followed for decontamination and sterilization
Manufacturer IFUs must be available and followed for all loaner instruments to ensure proper decontamination and sterilization according to validated methods.
During the evaluation of decontaminated instruments, a technician finds residual soil in a box-lock joint. What should happen next?
Answer: Return the instrument to decontamination for manual cleaning before repackaging
Residual soil on instruments must be removed through additional manual cleaning before packaging and sterilization, as soil can interfere with the sterilization process.
What does it mean when a sterilization load record shows a 'fault' notation on a vacuum pulse during a pre-vacuum steam sterilization cycle?
Answer: There was a potential air leak or malfunction that may have compromised steam penetration
A fault during the vacuum pulse phase indicates a potential malfunction affecting air removal, which could compromise steam penetration and cycle validity.
When evaluating event-related sterility, which factor most directly threatens the sterility of a packaged instrument?
Answer: Damage to or compromise of the package
Event-related sterility means an item remains sterile until the package is compromised; physical damage to packaging is the primary threat, not elapsed time.
A CS technician discovers that a set of instruments was sterilized using the wrong cycle type (e.g., gravity instead of pre-vacuum as required by the IFU). What is the correct evaluation?
Answer: Reject the load because the validated sterilization method was not followed
Sterilization must follow validated cycle parameters specified in the manufacturer's IFU; using an incorrect cycle type invalidates the process regardless of BI results.
Which of the following best describes the purpose of performing a daily air removal test (Bowie-Dick test) on a pre-vacuum sterilizer?
Answer: To ensure air is effectively removed so steam can penetrate porous loads
The Bowie-Dick test verifies that the sterilizer can effectively remove air from the chamber, which is essential for steam to penetrate porous loads uniformly.
