What must be done with instruments that cannot be sterilized with an autoclave?

  1. Disposed of after one use

  2. Sterilized with an EPA-approved disinfectant

  3. Cleaned with soap and water

  4. Air-dried for 24 hours

The correct answer is: Sterilized with an EPA-approved disinfectant

Instruments that cannot be sterilized with an autoclave, such as those made of plastic or with electronic components, should be sterilized with an EPA-approved disinfectant. Option A is not the most effective or cost-efficient solution as it would require frequent replacement of instruments. Option C is a necessary first step, however, it does not provide a high enough level of sterilization. Option D is also not a sufficient method of sterilization on its own. Therefore, option B is the best choice for ensuring that these instruments are properly sterilized.
