STERILE PROCESSING LATEST EVALUATION TEST
QUESTIONS AND ANSWERS SURE A+
✔✔What are enzymes ? - ✔✔Catalysts that breakdown or "digest" large organic
molecules to facilitate their removal.
✔✔Protease - ✔✔Enzymes that break down proteins.
✔✔Lipase - ✔✔Enzymes that break down fats.
✔✔Amylase - ✔✔Enzymes that break down starches.
✔✔Free Rinsing - ✔✔Removal of any residue of cleaning agents and chemicals
remaining after the cleaning process.
✔✔What is the preferred transportation method ? Why? - ✔✔Closed transport system to
avoid cross contamination.
✔✔Please fill in the blanks on the pH table. - ✔✔-_____ _______
-_____ _______
-_____ Neutral
-_____ _______
-_____ _______
✔✔Sequestering agent - ✔✔Chemicals that remove hard water minerals.
, ✔✔Surfactant - ✔✔A surface-acting agent that lowers the surface tension of a liquid so
it can penetrate deeper.
✔✔Chelating agent - ✔✔Chemicals that hold hard water minerals in solution and
prevent soaps or detergents from reacting with minerals.
✔✔3-sink setup - ✔✔1. Wash sink-water and detergent
2. Intermediate rinse sink- plain deionized water
3. Final rinse sink- deionized water
✔✔Water temperatures should be below ____ to prevent coagulation. - ✔✔110 degrees
F
✔✔Name 8 items that should not be placed in the ultrasonic cleaner. - ✔✔1. Chrome-
plated instruments
2. Ebonized instruments
3. Plastic
4. Cork
5. Glass
6. Wood
7. Chrome
8. Rubber
✔✔What process is used for Ultrasonic Cleaners? please explain. - ✔✔Cavitation
process, which is when ultrasonic vibrations create tiny air bubbles that grow larger until
they implode (collapse). This process reaches small areas that brushes cannot reach.
✔✔What process is used for Mechanical Washers? - ✔✔Impingement, which is a spray
force of water.
✔✔What are prions? What do they cause? - ✔✔A sort of virus that is hard to kill, has a
misfolded protein, it lacks DNA and RNA. It causes Mad Cow Disease, and TSE
(Transmissible Spongiform Encephalopathy)
✔✔Shelf life vs Use life? - ✔✔-Shelf life: Length of time a disinfectant can be properly
stored till expired.
-Use life: Length of time or number of times disinfectant can be used until efficiency
(strength) or disinfectant is diminished.
✔✔What is MEC and what level should it be at? - ✔✔MEC is a test used to check the
effectiveness of the chemical concentration level, which should be at 0.3% or higher for
OPA.
