Removing or killing every vegetative cell, endospore and virus from an item achieves:

  1. Sterilisation
  2. Stabilisation
  3. Standardisation
  4. Stimulation
Show answer and solution

Correct answer: A. Sterilisation

1. Nothing living is left behind at all. 2. Even tough endospores must be destroyed. 3. That level is sterilisation. _Source: OpenStax Microbiology, Chapter 13, Control of Microbial Growth._

Inactivating most microbes on a surface with chemicals or heat is called:

  1. Discoloration
  2. Disinfection
  3. Distillation
  4. Distribution
Show answer and solution

Correct answer: B. Disinfection

1. Some microbes still survive the treatment. 2. It is applied to surfaces rather than skin. 3. That process is disinfection. _Source: OpenStax Microbiology, Chapter 13, Control of Microbial Growth._

Because some microbes survive it, a disinfected item is not considered:

  1. Sterile
  2. Storable
  3. Suitable
  4. Sellable
Show answer and solution

Correct answer: A. Sterile

1. Sterilisation kills everything present. 2. Disinfection only reduces the load. 3. So the item is not sterile. _Source: OpenStax Microbiology, Chapter 13, Control of Microbial Growth._
