CRCST Instrument Processing 5

Question 1

During inspection of instruments before packaging, which quality check should be performed on scissors?

Accepted Answer

Test cutting ability by cutting through a test material appropriate for that instrument

Answer

Verify the instrument opens to a 90-degree angle under load

Answer

Measure blade length with calipers to confirm manufacturer specifications

Answer

Check that the instrument is magnetized to pass a metal detector

Question 2

Ethylene oxide (EO) sterilization requires a mandatory aeration period after the cycle primarily to:

Accepted Answer

Dissipate toxic EO residues from items before they are safe for patient use

Answer

Allow the chamber to return to room temperature before unloading

Answer

Rehydrate biological indicators to allow accurate reading

Answer

Allow sterilization packaging to fully seal and bond

Question 3

Which of the following is a key principle when loading a steam sterilizer to ensure effective sterilization?

Accepted Answer

Position items to allow steam circulation and condensate drainage

Answer

Pack items tightly to maximize load capacity per cycle

Answer

Place all heavy packs on the top shelf to allow gravity drainage

Answer

Wrap all items in double layers of plastic to protect them from moisture

Question 4

A flash sterilization (Immediate Use Steam Sterilization/IUSS) cycle is most appropriately used when:

Accepted Answer

An instrument is dropped in the OR and is urgently needed with no sterile replacement available

Answer

Routine processing of all orthopedic instrument sets for scheduled cases

Answer

Sterilizing items that cannot withstand a gravity or prevacuum cycle

Answer

Processing heat-sensitive cameras and power tools for a case

Question 5

What is the primary hazard of inadequate rinsing of enzymatic detergent from instruments before sterilization?

Accepted Answer

Residual detergent can cause patient tissue irritation or toxic reactions

Answer

The detergent will neutralize the sterilant, reducing efficacy

Answer

Enzyme residue accelerates corrosion of instrument surfaces

Answer

Detergent foam will contaminate the sterilizer chamber filters

Question 6

Which organization publishes the ANSI/AAMI standards that govern sterilization practices in healthcare facilities in the United States?

Accepted Answer

Association for the Advancement of Medical Instrumentation (AAMI)

Answer

The Joint Commission (TJC)

Answer

Centers for Disease Control and Prevention (CDC)

Answer

Occupational Safety and Health Administration (OSHA)

Question 7

When a loaner instrument set arrives from a vendor on the day of surgery, the sterile processing technician should:

Accepted Answer

Decontaminate, inspect, package, and sterilize the set according to facility policy before use

Answer
