What is a process that destroys all microorganisms, both pathogenic and nonpathogenic, including spores and viruses?

• A. Disinfection
• B. Sanitization
• C. Sterilization
• D. Cleaning

Answer: (C)

Sterilization is the process that eliminates all microorganisms, including hardy spores and viruses, from an item or surface. It achieves the highest level of microbial control and is essential for instruments that enter sterile tissues or the bloodstream. Methods such as steam under pressure (autoclaving), dry heat, chemical sterilants, and irradiation are used to reach this level of destruction. Disinfection removes many pathogens but may not kill spores or all viruses; sanitization lowers the overall microbial load to safe levels; cleaning removes soil and some microbes but does not guarantee complete destruction. Because spores are highly resistant to many treatments, only sterilization ensures no viable organisms remain.
