Which sterilization method is most appropriate for heat-sensitive, moisture-sensitive items such as fiber optic cables?
Answer: Ethylene oxide (EO) gas
Ethylene oxide gas sterilizes at low temperatures and is safe for heat- and moisture-sensitive items like fiber optic cables.
A sterile field has been set up and left unattended for 30 minutes. What is the correct action?
Answer: Consider the field contaminated and set up a new one
A sterile field that has been left unattended and unwatched is considered contaminated and must be replaced.
What is the standard biological indicator organism used to verify steam autoclave sterilization efficacy?
Answer: Geobacillus stearothermophilus
Geobacillus stearothermophilus spores are the standard biological indicator for steam sterilization because of their high heat resistance.
When passing a sharp instrument during surgery, the BEST method to maintain safety and sterility is:
Answer: Use the neutral/hands-free technique on a designated zone
The neutral or hands-free technique places the instrument in a designated zone to prevent needlestick injuries while maintaining sterility.
Which of the following packaging materials is NOT acceptable for steam sterilization?
Answer: Aluminum foil
Aluminum foil does not allow steam penetration and is not acceptable for steam sterilization.
During a procedure, the scrub technologist's gown sleeve accidentally touches the non-sterile kick bucket. What should occur?
Answer: Inform the surgeon and change gown
Any contact between a sterile gown and a non-sterile surface renders that area contaminated; the gown must be changed.
What does a Class 5 chemical integrator (integrating indicator) confirm when found acceptable after sterilization?
Answer: That all critical sterilization parameters were met
Class 5 integrating indicators respond to all critical sterilization parameters (time, temperature, and steam) to confirm acceptable conditions.
