Manufacturers' Instructions for Use (IFUs) provide legally validated, device-specific reprocessing instructions that must be followed to ensure safety and device integrity.

Question 2

What is the purpose of a sterilization load control number (lot control number)?

Accepted Answer

To enable rapid identification and recall of items from a specific sterilization cycle

Answer

Lot control numbers link sterile items to a specific sterilizer cycle, enabling targeted recall if a sterilization failure is discovered.

Question 3

Which condition would make a rigid sterilization container unacceptable for use?

Accepted Answer

Container has visible cracks, a damaged filter, or a missing locking mechanism

Answer

Cracks, damaged filters, or non-functioning locking mechanisms compromise the barrier integrity of a rigid container, rendering it unacceptable for sterilization.

Question 4

What is the primary function of enzymatic detergents used in instrument cleaning?

Accepted Answer

To break down organic soil such as blood, protein, and fat through enzyme activity

Answer

Enzymatic detergents contain protease, lipase, and amylase enzymes that chemically break down organic matter, improving cleaning efficacy particularly in lumens and hinges.

Question 5

When using a flash (immediate-use) steam sterilization cycle, what is a key limitation compared to terminal sterilization?

Accepted Answer

Items sterilized by flash cannot be stored and must be used immediately

Answer

Immediate-use steam sterilization (IUSS/flash) is intended for emergency use only; items cannot be packaged for storage and must be transported aseptically to the point of use immediately.
