Sample CRCST questions
These examples show the style of practice: choose an answer, then study the rationale.
Question 1
Which action should happen at the point of use before instruments leave the procedure area?
Why: Point-of-use care prevents soil from drying and makes later decontamination more effective.
Question 2
Which Spaulding category requires sterilization before patient use?
Why: Critical items enter sterile tissue or the vascular system, so they require sterilization.
Question 3
What is the main purpose of a biological indicator?
Why: Biological indicators contain resistant spores and provide direct evidence that sterilization conditions were lethal.
