1. What is the first step in the infection control process for tools and implements?
A) Disinfection with an EPA-registered product
B) Sterilization using an autoclave
C) Cleaning to remove all visible debris
D) Sanitizing with soap and water
Answer: C) Cleaning to remove all visible debris
Rationale: Cleaning is the foundational first step in infection control. Removing
all visible dirt, oils, and debris from tools is essential because disinfection and
sterilization cannot be effective if the surface is not clean .
2. Which level of infection control destroys all microorganisms, including
bacterial spores?
A) Sanitation
B) Disinfection
C) Sterilization
D) Antiseptic treatment
Answer: C) Sterilization
, Rationale: Sterilization is the highest level of infection control and destroys all
microbial life, including highly resistant bacterial spores. This is achieved through
methods like autoclaving (steam under pressure) or dry heat .
3. What is the minimum contact time generally required for EPA-registered
disinfectants to be effective?
A) 1 minute
B) 5 minutes
C) 10 minutes
D) 30 minutes
Answer: C) 10 minutes
Rationale: EPA-registered disinfectants typically require a contact time of 10
minutes to effectively kill pathogens. Always follow the manufacturer's specific
label instructions for correct contact time, as it can vary .
4. Which of the following is the correct procedure for disinfecting metal
implements like shears or clipper blades?
A) Wash with soap and water, then wipe with alcohol
B) Clean, completely immerse in EPA-registered disinfectant for 10 minutes,
rinse, and dry
C) Boil in water for 5 minutes
D) Wipe with a disinfectant wipe only
Answer: B) Clean, completely immerse in EPA-registered disinfectant for 10
minutes, rinse, and dry
Rationale: Proper disinfection requires a multi-step process: first, thoroughly
clean the implement to remove debris; second, completely immerse it in an EPA-
registered disinfectant for the full contact time; finally, rinse and dry it .
5. Before disinfecting combs and brushes, what is the required first step?
A) Spray them with alcohol
B) Clean them with soap and warm water
C) Soak them in bleach
D) Place them in an autoclave

A) EPA-registered hospital-grade disinfectant
B) Boiling water
C) Ultraviolet (UV) sanitizer as the sole method
D) Barbicide

A) Sterilization
B) Decontamination
C) Sanitation
D) Antiseptic treatment
Answer: B) Decontamination

9. Rinsing with water is NOT considered which level of decontamination?
A) The first step
B) A preliminary cleaning step
C) A level of decontamination
D) An effective cleaning method for removing debris
Answer: C) A level of decontamination
Rationale: Rinsing alone is not a level of decontamination. It is a preliminary
step to remove visible debris but does not reduce or destroy pathogens on its own .
10. What is the primary route of transmission for fungal infections like ringworm
(Tinea capitis) in a barbershop?
A) Airborne transmission
, B) Direct contact with contaminated surfaces or tools
C) Bloodborne transmission
D) Foodborne transmission
