Assembly and Packaging Systems Flashcards

When assembling an instrument tray, what is the most important function of the inspection process?

Answer: To verify the cleanliness, function, and integrity of each instrument

While counting and neatness are important, the primary function of inspection is to ensure patient safety. This involves checking each instrument for residual soil (cleanliness), proper working order (function, e.g., scissors cut, forceps align), and damage like cracks or rust (integrity).

Which of the following is an unacceptable packaging material for steam sterilization?

Answer: Polyethylene (plastic) pouches

Polyethylene, a common type of plastic, cannot withstand the high temperatures of steam sterilization and will melt. Packaging materials must be able to withstand the sterilization process while also allowing the sterilant to penetrate and then maintaining sterility afterward.

According to CSA standards, what is the generally accepted maximum weight for a wrapped instrument tray?

Answer: 11.4 kg (25 lbs)

The CSA standard Z314 sets the maximum weight for wrapped instrument trays at 11.4 kg (25 lbs). This limit is based on ergonomic safety for staff and ensuring effective sterilant penetration and drying within the sterilizer.

Where should a Type 5 internal chemical indicator be placed within an instrument tray?

Answer: In the geometric center or most challenging location for sterilant penetration

The internal chemical indicator's purpose is to verify that sterilant reached the most difficult-to-sterilize area of the pack. Placing it in the center or the area of greatest density ensures that if it passes, it's highly likely the entire contents of the tray were exposed to the proper conditions.

When double-pouching items for sterilization, how should the inner pouch be placed relative to the outer pouch?

Answer: Paper side of the inner pouch to the plastic side of the outer pouch

The correct method is paper-to-plastic (or film). This orientation ensures that the sterilant can penetrate through the paper side of the outer pouch and then the paper side of the inner pouch. It also allows for aseptic presentation, as the inner pouch can be clearly seen and removed without contamination.

What is a key advantage of using rigid sterilization containers over wrapped trays?

Answer: They provide superior protection against physical damage during transport and storage

The hard, sealed shell of a rigid container offers excellent protection for delicate instruments, preventing damage from impact or compression. This helps maintain the integrity of both the instruments and the sterile barrier system, reducing the risk of contamination.

At a minimum, what information must be included on the label of a sterilized package?

Answer: A description of the contents, sterilizer ID, load number, and expiration date

Proper labeling is crucial for tracking and quality assurance. A label must clearly identify the contents, the specific sterilizer used, the unique load number for that sterilizer on that day, and the expiration date (or a statement of event-related sterility), allowing for a full recall if a sterilization failure is detected.
