NIC Esthetician Written ExamSafety and Infection ControlMedium

An esthetician is preparing to use a multi-use tool that was previously cleaned and disinfected. Before placing it in the UV sanitizer, what crucial step must be ensured regarding the tool's condition?

  1. AIt needs to be wrapped in a sterile pouch for further sterilization.
  2. BIt should be coated with a thin layer of mineral oil for protection.
  3. CIt must be slightly damp to allow for better UV penetration.
  4. DIt must be completely dry to prevent rust and maintain efficacy.
Show answer & explanation

Correct answer: D. It must be completely dry to prevent rust and maintain efficacy.

Tools must be completely dry before being placed into a UV sanitizer. Moisture can hinder the effectiveness of the UV light and promote rust or corrosion on the tools.

Why the other options are wrong

  • A. UV sanitizers are for storage of disinfected tools, not for sterilization. Tools are not wrapped for this step.
  • B. Coating tools with oil is not part of the sanitization or disinfection process and could create a barrier to UV light.
  • C. Dampness can interfere with UV germicidal action and contribute to rust or corrosion.

UV Sanitizer Use

A device that uses ultraviolet light to keep already-disinfected tools sanitized and free from dust and environmental contaminants, not to sterilize or disinfect them.

  • Only for cleaned and disinfected tools.
  • Tools must be completely dry before placement.
  • Does not sterilize; only maintains a sanitary condition.
  • Acts as a storage unit, protecting against recontamination.

Memory trick: Clean, Dry, Disinfect, then Store. That's the tool care score!
