Sterilization and Disinfection Quiz

1. Which of the following are true about steam (moist heat) sterilization in a Sterile Processing Department?

Uses pressurized steam to denature proteins.
Operates at low temperatures (under 60°C).
It is primarily used for heat-sensitive devices.
Requires appropriate time, temperature, and pressure for effective sterilization.

2. Which of the following are accurate regarding low-temperature chemical sterilization methods?

Ethylene Oxide (EtO) is used as a low-temperature sterilization method.
Hydrogen Peroxide Gas Plasma is a low-temperature method appropriate for delicate devices.
Both methods require high heat cycles.
EtO requires long aeration periods to remove toxic residues.
They are preferred for complex devices containing electronics and polymers.

3. Select the correct statements about the Spaulding Classification.

Critical items require sterilization.
Semi-critical items require high-level disinfection at a minimum.
Non-critical items require sterilization.
Non-critical items typically require low-level disinfection or cleaning.

4. Which of the following quality assurance methods are used in monitoring sterilization processes?

Physical monitoring via cycle printouts and gauges.
Chemical indicators that change color upon exposure.
Relying solely on the equipment's age without regular checks.
Biological indicators that incorporate resistant bacterial spores.
Customer satisfaction surveys.

5. Identify the disadvantages associated with Dry Heat Sterilization.

Requires higher temperatures and longer exposure times.
Poses a risk of damaging heat-sensitive materials.
Ensures efficient heat transfer and short cycle times.
Can lead to material degradation from prolonged heat exposure.
Is generally suitable for sterilizing plastics and rubber.
