NIC Barber Written (Theory) ExamScientific ConceptsEasy
A barber is preparing their workstation for a client who has a known highly contagious skin infection. To effectively eliminate all microbial life, including bacterial spores, from the non-porous tools, which level of decontamination is required?
- AAntisepsis
- BSanitization
- CDisinfection
- DSterilization
Show answer & explanationAnswer & explanation
Correct answer: D. Sterilization
Sterilization is the highest level of decontamination and is required to destroy all microbial life, including bacterial spores, which are highly resistant. Sanitation and disinfection do not kill spores, and antisepsis is for living tissue.
Why the other options are wrong
- A. Antisepsis is the process of reducing microorganisms on living tissue, not inanimate objects.
- B. Sanitization significantly reduces the number of pathogens but does not eliminate all microbial life or spores.
- C. Disinfection kills most microorganisms on non-porous surfaces but does not reliably kill bacterial spores.
Sterilization
The most rigorous level of decontamination, sterilization completely destroys all microbial life, including bacteria, viruses, fungi, and bacterial spores, on inanimate objects.
- Highest level of decontamination.
- Eliminates bacterial spores.
- Typically involves autoclaving or dry heat for barbers.
Memory trick: Sanitizers make it Safe, Disinfectants are Deadly, Sterilizers are Super-deadly.
