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