SPD - Sterile Processing Department Technician Packaging for Sterilization Questions and Answers 1 — Questions and Answers
Question 1: An SPD technician is preparing a lightweight, low-profile instrument for steam sterilization. Which of the following packaging materials is most appropriate for this item?
- Woven textile wrap
- Rigid sterilization container
- Paper-plastic pouch (Correct answer)
- Polypropylene wrap
Correct answer: Paper-plastic pouch
Paper-plastic pouches are ideally suited for packaging lightweight, low-profile, and individual instruments for sterilization. Woven wraps and rigid containers are typically used for heavier instrument sets, and while polypropylene wrap could be used, a pouch offers better visibility and organization for a single, small item.
Question 2: When preparing an instrument tray for steam sterilization, what is the maximum recommended weight for the set, including the container?
- 15 lbs
- 20 lbs
- 25 lbs (Correct answer)
- 30 lbs
Correct answer: 25 lbs
According to AORN (Association of periOperative Registered Nurses) guidelines, the total weight of an instrument tray, including the container and its contents, should not exceed 25 pounds to ensure proper sterilant penetration and to facilitate safe handling.
Question 3: A sterile processing technician notices a small tear in the outer layer of a wrapped instrument set just before it is scheduled to be sent to the operating room. What is the appropriate course of action?
- Tape the tear securely with sterilization indicator tape.
- Send the set to the OR but inform the staff about the tear.
- Disregard the tear as long as the inner wrap is intact.
- Return the entire set to the decontamination area for complete reprocessing and repackaging. (Correct answer)
Correct answer: Return the entire set to the decontamination area for complete reprocessing and repackaging.
Any compromise to the integrity of the packaging, such as a tear, renders the item unsterile. The set must be completely reprocessed, starting from the decontamination phase, to ensure patient safety. Taping the tear is not an acceptable practice as it does not guarantee sterility.
Question 4: Which of the following is a critical requirement for any packaging material used for terminal sterilization?
- It must be impermeable to all gases and liquids.
- It must be compatible with all forms of sterilization.
- It must allow for penetration of the chosen sterilant and maintain sterility post-sterilization. (Correct answer)
- It must be reusable for a minimum of 50 cycles.
Correct answer: It must allow for penetration of the chosen sterilant and maintain sterility post-sterilization.
A fundamental principle of sterilization packaging is that it must permit the sterilizing agent (e.g., steam, ethylene oxide) to penetrate and reach all surfaces of the device, and then act as a barrier to prevent microbial contamination after sterilization until the point of use.
Question 5: When using non-woven, single-use sterilization wrappers, what is the primary material they are typically made from?
- 140-thread count cotton muslin
- Polypropylene (Correct answer)
- Linen and polyester blend
- Tyvek
Correct answer: Polypropylene
Modern synthetic non-woven sterilization wraps are most commonly made from polypropylene, using spunbond and meltblown layers to create a durable material with excellent barrier properties. Cotton muslin and linen blends are examples of woven, reusable textiles.
Question 6: An SPD technician is double-pouching an instrument for aseptic presentation in the operating room. According to best practices, how should this be performed?
- Fold the inner pouch before placing it inside the outer pouch.
- Place the inner pouch facing the plastic side of the outer pouch.
- Use two different sizes of pouches, placing the smaller one inside the larger one.
- Place the inner pouch with the paper side facing the paper side of the outer pouch. (Correct answer)
Correct answer: Place the inner pouch with the paper side facing the paper side of the outer pouch.
When double-pouching, the inner pouch should be placed inside the outer pouch with the paper side of the inner pouch facing the paper side of the outer pouch. This alignment allows for adequate sterilant penetration and subsequent drying. While facility policies should always be followed, this paper-to-paper technique is a common best practice.
