Which three terms comprise the principles of asepsis?

• A. Contamination control, sanitization, sterilization
• B. Sanitization, disinfection, sterilization
• C. Cleaning, sanitization, disinfection
• D. Sterilization, antisepsis, disinfection

Answer: (B)

Asepsis relies on reducing or removing microorganisms to prevent infection, using levels of decontamination that match the risk and use of the item. The three terms that describe these levels are sanitization, disinfection, and sterilization. Sanitization means cleaning to lower the microbial load on a surface or object to a safe level. It’s appropriate for many everyday surfaces and noncritical items, where the goal is to reduce risk rather than achieve complete sterility. Disinfection goes further: it reduces or eliminates many pathogenic organisms on inanimate surfaces and objects, though some spores may survive. It’s used for items that should be free of most harmful microbes but do not need to be completely sterile. Sterilization is the most rigorous level, destroying all forms of microbial life, including spores, and is required for instruments and materials that will enter sterile body sites or come into contact with normally sterile tissues. These three together provide a practical framework for maintaining asepsis in clinical settings: you start with cleaning, apply sanitization to reduce overall load, use disinfection on surfaces and equipment to kill most pathogens, and reserve sterilization for items that must be completely free of microbes. Others concepts like antisepsis involve living tissue rather than environmental or instrument decontamination, so they don’t fit as the set describing these asepsis levels.
