Occupational Safety and Health Administration (OSHA) SLC Practice Exam

What is the purpose of medical asepsis?

1. To completely eliminate all microorganisms

2. To maintain a sterile environment

3. To reduce the number of pathogens in the environment

4. To ensure all medical instruments are sterilized

The correct answer is: To reduce the number of pathogens in the environment

The purpose of medical asepsis is to reduce the number of pathogens in the environment rather than to achieve complete sterilization. This is a critical concept in healthcare settings because it aims to minimize the risk of infection by decreasing the number of harmful microorganisms that can be present on surfaces, objects, and in the air. Medical asepsis employs various techniques such as hand hygiene, proper cleaning of surfaces, and the use of barriers like gloves and gowns to suppress the growth and spread of pathogens. This approach is essential in controlling infections, especially in environments where individuals may be immunocompromised or have open wounds. In contrast, complete elimination of all microorganisms is the goal of surgical asepsis, which is more stringent and involves sterilization techniques that are not typically applied in standard medical procedures aimed solely at maintaining cleanliness. Maintaining a sterile environment is also a component of surgical asepsis rather than medical asepsis. While sterilization of medical instruments is crucial, it is a specific practice that feeds into the broader scope of aseptic techniques, but it does not encompass the full goal of medical asepsis itself.
