Utah Master Esthetician Practice Exam

When cleansing an instrument, at what stage should you lubricate it?

1. Before disinfection

2. After disinfection, before sterilization

3. After sterilization

4. During the cleaning process

The correct answer is: After disinfection, before sterilization

Lubricating an instrument after disinfection and before sterilization is important for several reasons. Disinfection reduces the number of pathogens on the surface of the instrument, making it safer to handle, while sterilization ensures the elimination of all forms of microbial life. By lubricating at this stage, the instrument is protected from damage or corrosion that may occur during the sterilization process, especially if it undergoes autoclaving or other high-heat methods. Proper lubrication can enhance the lifespan of the instrument and also facilitate its smooth operation, preventing wear and tear that could compromise its effectiveness for future use. Lubrication prior to disinfection would allow contaminants to remain on the instrument during the cleaning process, and lubricating during cleaning may interfere with the effectiveness of detergents and disinfectants. If one were to lubricate after sterilization, the lubrication could also reintroduce contaminants that may compromise the sterility of the instrument. Thus, the correct timing for lubrication is pivotal for maintaining the integrity and functionality of esthetic instruments.
