CIS - Certified Instrument Specialist Instrument Inspection and Testing Questions and Answers

Question 1

A Certified Instrument Specialist is testing the sharpness of a pair of standard scissors that are 5 inches long. According to industry best practices, which testing material should be used?

Accepted Answer

Red test material

Answer

Red sharpness testing material is specifically designated for testing scissors that are 4.5 inches or larger. Yellow material is used for scissors 4 inches or smaller. Index cards are used for rongeurs, and dowel rods are used for osteotomes.

Question 2

During the inspection of a laparoscopic instrument with insulation, a technician notes no visible cracks or peels. However, to ensure patient safety from unintended burns, what is the essential next step?

Accepted Answer

Use an insulation integrity tester

Answer

Visual inspection alone is insufficient to detect microscopic pinholes or tears in insulation that can cause inadvertent burns to the patient during electrosurgery. An insulation integrity tester is specifically designed to detect these unseen defects by passing a low-voltage electrical current through the instrument.

Question 3

Which of the following is the PRIMARY reason for meticulously inspecting surgical instruments for cleanliness and damage after decontamination and prior to sterilization?

Accepted Answer

To ensure the sterilization process will be effective and to prevent patient harm

Answer

The primary purpose of inspection is to ensure patient safety. If an instrument is not perfectly clean (free of bioburden), the sterilization process may not be effective. Additionally, damaged instruments with scratches, pits, or cracks can harbor microorganisms and pose a risk of breaking during a procedure, potentially harming the patient.

Question 4

A sterile processing technician is inspecting a needle holder. What is the correct method to test its functionality?

Accepted Answer

Clamp a needle in the jaw and ensure it cannot be easily turned

Answer

The specific function of a needle holder is to grasp a needle firmly. Therefore, the correct test is to clamp a needle and ensure the instrument can hold it securely without it turning or moving. Holding jaws to a light is for scissors, and tapping ratchets is a general test for any locking mechanism.

Question 5

When inspecting a rongeur, what is the appropriate material to use for a functional sharpness test?

Accepted Answer

An index card

Answer

A rongeur's function is to bite and remove pieces of bone. An index card provides a suitable material to simulate this action, and a clean, sharp bite out of the card indicates the rongeur is functioning correctly. Dowels are for osteotomes, red test material for large scissors, and gauze is not firm enough to test a rongeur.
