New York State Infection Control Practice Test 2025 – Comprehensive Exam Prep

Disinfection is a critical process utilized in various healthcare and sanitation settings to eliminate most pathogenic microorganisms. It specifically targets and reduces the number of viable pathogens, with the primary goal of minimizing the risk of infection. Disinfectants work by using chemical agents or physical methods to destroy or inactivate these microorganisms on surfaces and inanimate objects.

While sterilization entails a more comprehensive approach by eliminating all forms of microbial life, including bacterial spores, disinfection is sufficient for most routine applications where complete sterility is not necessary. In contexts such as medical facilities, disinfecting surfaces and equipment helps ensure that infectious agents do not lead to the spread of disease.

In contrast, cleaning generally involves removing dirt and impurities from surfaces, but it does not necessarily kill microorganisms. Decontamination is a broader term that refers to the process of cleaning, disinfection, and sterilization, depending on the level of microbial control required. However, disinfection specifically addresses the elimination of most pathogenic microorganisms, making it the most appropriate answer in this context.
