At what point should a lubricant be applied to a tool during disinfection?

The correct answer is that lubricant should be applied after cleaning and disinfection, but before sterilization. This sequence is essential in ensuring that the tools are properly prepared for the sterilization process.

Cleaning removes dirt, debris, and organic matter from the tools, followed by disinfection to kill most pathogens. Once these two steps are completed, applying lubricant facilitates the smooth functioning of the tools during sterilization and ensures they remain in optimal condition. If lubricant were applied before cleaning, it could interfere with the ability to effectively clean the tools, as it may trap debris and bacteria. Additionally, applying lubricant during the disinfection process or after sterilization would not effectively address the needs of the tools, as they would either be contaminated while trying to disinfect or potentially compromised in their sterilized state.
