Question 1

When assembling a micro-surgical instrument tray, why should individual instruments be separated by foam inserts rather than stacked together?

Accepted Answer

To allow sterilant penetration and prevent damage to delicate tips

Answer

Foam inserts protect delicate micro-instrument tips from contact damage and ensure sterilant reaches all surfaces by preventing instruments from nesting together.

Question 2

A CS OR liaison is reviewing a preference card for a total knee replacement. The card calls for a tourniquet cuff. Which department is typically responsible for applying the tourniquet to the patient?

Accepted Answer

Anesthesia team or circulating nurse in the OR

Answer

Tourniquet application to the patient is performed by the circulating nurse or anesthesia team in the OR, though CS ensures the equipment is functional and delivered.

Question 3

Which statement CORRECTLY describes the principle of 'first in, first out' (FIFO) as it applies to CS sterile storage?

Accepted Answer

Older sterilized items should be used before newer ones to prevent expiration of event-related sterility

Answer

FIFO rotation ensures that older sterilized packages are pulled and used first, supporting event-related sterility maintenance and preventing packs from remaining on shelves indefinitely.

Question 4

During a post-case instrument return, the CS technician observes brown discoloration on stainless steel clamps. This MOST likely indicates:

Accepted Answer

Rust or staining from saline, blood, or improper processing

Answer

Brown discoloration on stainless steel instruments typically indicates rust or staining caused by chloride exposure from saline, inadequate rinsing, or drying issues.

Question 5

What is the CORRECT approach when a CS technician receives a flash (immediate-use) sterilization request for a dropped instrument during surgery?

Accepted Answer

Follow the instrument manufacturer's IFU and facility policy for IUSS, documenting the cycle and reason

Answer

IUSS (immediate-use steam sterilization) must follow the manufacturer's IFU and facility policy, with full documentation of the load, reason, and patient identification.
