Instrument Assembly and Packaging Flashcards

What is the primary purpose of the inspection step before instrument assembly and packaging?

Answer: To verify instruments are clean, functional, and free of damage before packaging for sterilization

Inspection verifies that instruments are visibly clean, structurally intact, and fully functional before packaging — ensuring that only properly processed, working instruments are sterilized and sent to patient care areas.

When inspecting scissors during the assembly process, which functional test is most appropriate?

Answer: Test scissors by cutting a thin material (such as gauze or test material) to verify they cut cleanly to the tips

Scissors should be tested by cutting an appropriate thin material cleanly to the blade tips. Scissors that do not cut cleanly, catch, or fail to cut to the tips are defective and should be removed from service.

What is the recommended maximum weight for a standard instrument tray/set prepared for sterilization?

Answer: 5 kg (11 lbs)

CSA Z314 recommends a maximum weight of 10 lbs (approximately 4.5–5 kg) for wrapped instrument sets to allow adequate steam penetration and drying within the package.

Which of the following best describes the correct method for wrapping instruments using the sequential (envelope) wrap technique?

Answer: Use two separate sheets of wrapping material sequentially, each folded in an envelope pattern, to create a double-barrier package

The sequential wrap technique uses two separate sheets of wrap — each applied individually in an envelope fold — to create a double-barrier package that maintains sterility barrier integrity when opened aseptically.

What does the term 'event-related sterility' mean in the context of sterile package storage?

Answer: A package is considered sterile until an event occurs (such as damage, moisture, or opening) that compromises the integrity of the sterile barrier

Event-related sterility means that a properly sealed, intact sterile package maintains sterility indefinitely until a compromising event occurs — such as tears, moisture, dropped package, or failed seal — not based on a fixed expiry date.

What information must be included on the label of every sterilized package per CSA Z314?

Answer: Load control number, sterilizer ID, cycle date, and contents description (and user/department if applicable)

Each sterile package label must include the load control number (sterilizer ID + cycle/date), contents description, and destination department — providing traceability and identification for recall and inventory management.
