Medical Device Reprocessing Association of Ontario (MDRAO) Practice Exam

For what purpose are alcohols primarily used in the context of medical devices?

1. As a general surface disinfectant

2. As a drying agent on lumen devices

3. As a sterilant for surgical instruments

4. As a cleaning agent for reusable devices

The correct answer is: As a drying agent on lumen devices

In the context of medical devices, alcohols are primarily employed as a drying agent on lumen devices. This usage leverages the rapid evaporation properties of alcohols, which allows for effective drying of instruments that have narrow passageways or lumens. Maintaining a dry environment is crucial after reprocessing to prevent the growth of microorganisms and ensure that devices are safe for use. Alcohols can help eliminate residual moisture that may promote bacterial growth, thereby contributing to infection control. While alcohols can serve other functions, such as general surface disinfection or cleaning agents and may have some use as sterilants, these roles are generally not their primary application in medical device reprocessing. For example, other agents or methods are preferred for thorough disinfection or sterilization processes, which may involve heat, ethylene oxide, or chemical agents that provide a higher level of assurance for eliminating all forms of microbial life.
