What is the final phase of hydrogen peroxide gas plasma sterilization?

  1. Plasma

  2. Exposure

  3. Aeration

  4. Venting

The correct answer is: Venting

The final phase of hydrogen peroxide gas plasma sterilization is venting. Venting allows the removal of any residual hydrogen peroxide gas from the sterilization chamber, ensuring that instruments are safe for handling and use. The other options - plasma, exposure, and aeration - are not the final phase of the sterilization process but rather components or earlier stages of the overall sterilization cycle.
