Free MDRAO Assembly and Packaging Systems Questions and Answers

Question 1

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

Accepted Answer

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

Answer

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).

Question 2

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

Accepted Answer

Polyethylene (plastic) pouches

Answer

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.

Question 3

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

Accepted Answer

11.4 kg (25 lbs)

Answer

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.

Question 4

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

Accepted Answer

In the geometric center or most challenging location for sterilant penetration

Answer

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.

Question 5

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

Accepted Answer

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

Answer

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.
