- ASterilization
- BAntisepsis
- CDisinfection
- DSanitation
Show answer & explanationAnswer & explanation
Correct answer: A. Sterilization
Sterilization is the highest level of decontamination, involving the complete destruction of all forms of microbial life, including highly resistant bacterial spores. This is typically achieved using heat, such as in an autoclave.
Why the other options are wrong
- B. Antisepsis is the process of applying antiseptics to living tissue to reduce microorganisms.
- C. Disinfection destroys most, but not all, harmful microbes and does not kill spores.
- D. Sanitation is the lowest level, reducing microbes to safe levels.
Sterilization
The most rigorous process of decontamination, which completely destroys all microbial life, including bacterial spores.
- Highest level of infection control.
- Achieved by autoclaving (steam heat), dry heat, or chemical sterilants.
- Essential for critical items that enter sterile tissue.
Memory trick: Sanitize to clean, Disinfect to kill, Sterilize to destroy all evil.
