What this covers

Sample questions

Streptococci, the bacteria responsible for strep throat, grow in which arrangement?

  1. Rounded clusters, like a bunch of grapes
  2. Pairs, joined two at a time
  3. Curved chains, like a string of beads
  4. Tight spirals, like a corkscrew
Show the answer

C. Curved chains, like a string of beads

Streptococci are pus-forming cocci that line up in curved chains. Clusters describe staphylococci, which cause boils, pustules and abscesses, so the two are easy to mix up.

A disinfectant suitable for shop implements should carry label claims showing it is effective against which group of organisms?

  1. Bacteria and bacterial spores only
  2. Viruses and parasites only
  3. Fungi and bacterial spores only
  4. Bacteria, fungi and viruses
Show the answer

D. Bacteria, fungi and viruses

Shop disinfectants are EPA-registered products labeled bactericidal, fungicidal and virucidal. Disinfectants are not relied on to destroy bacterial spores; that requires sterilization.

Between clients, what is the correct way to treat clipper blades that cannot be immersed?

  1. Brush off the hair, then apply an EPA-registered disinfectant spray and leave it wet for the full contact time
  2. Brush off the hair, then place the clipper in an ultraviolet cabinet until the next client is seated
  3. Wipe the blades with a dry towel and add a drop of clipper oil to flush out anything left behind
  4. Blow the hair out of the blades, then run the clipper for a few seconds so friction heat kills germs
Show the answer

A. Brush off the hair, then apply an EPA-registered disinfectant spray and leave it wet for the full contact time

Hair and debris have to be removed first, then the blades are wetted with a registered disinfectant for the contact time on the label. An ultraviolet cabinet only stores items that are already disinfected; it does not disinfect them.
