CMDRT - Certified Medical Device Reprocessing Technician Instrument Assembly and Packaging Questions and Answers 2

Question 1

What is the primary purpose of inspecting instruments before assembly into sets?

Accepted Answer

To verify that instruments are clean, functional, and free of damage that could compromise sterilization or patient safety

Answer

Inspection ensures that each instrument is thoroughly clean (no residual soil), properly functioning (hinges, ratchets, cutting edges), and free of defects (cracks, pitting, corrosion) that could harbour microorganisms or fail during surgery.

Question 2

What types of packaging materials are acceptable for steam sterilization according to CSA standards?

Accepted Answer

Validated packaging materials such as sterilization wrap (SMS or crepe), peel pouches, rigid containers, and sterilization paper that allow steam penetration and maintain sterility

Answer

Packaging for steam sterilization must allow steam penetration during the sterilization cycle and maintain a microbial barrier during storage. CSA Z314.8 specifies that only validated packaging materials designed for sterilization should be used.

Question 3

What is the sequential wrapping technique and why is it recommended?

Accepted Answer

Using two layers of sterilization wrap applied in separate, sequential steps to provide a double barrier and facilitate aseptic presentation

Answer

Sequential double wrapping creates two independent microbial barriers. If the outer wrap is accidentally compromised during handling or storage, the inner wrap maintains sterility. It also facilitates aseptic opening in the sterile field.

Question 4

What information must be included on the label of a sterilized package?

Accepted Answer

Contents description, sterilizer number, cycle/load number, date of sterilization, and expiry date or event-related statement

Answer

Comprehensive labelling ensures traceability from the sterilized package back to the specific sterilization cycle. This is essential for quality assurance, recall management, and regulatory compliance.

Question 5

What is the maximum recommended weight for a wrapped instrument tray to be sterilized?

Accepted Answer

25 pounds (11.4 kg) as recommended by CSA and AAMI standards to ensure adequate steam penetration

Answer

Heavy trays can impede steam penetration to the centre of the package, resulting in sterilization failure. The 25-pound limit ensures that steam can reach all instrument surfaces within the standard sterilization cycle parameters.
