The U.S. food and drug administration classifies sterilization packaging as a:
Correct Answer
B. Class II medical device
Explanation
Sterilization packaging is classified as a class II medical device by the U.S. Food and Drug Administration. This classification suggests that sterilization packaging has a moderate level of risk associated with its use. Class II medical devices require special controls to ensure their safety and effectiveness. This classification indicates that sterilization packaging has been determined to be a necessary component in the sterilization process and must meet specific regulatory requirements to be marketed and used in healthcare settings.
2.
Which of the following is NOT an acceptable sterilization packaging material?
Correct Answer
C. Canvas
Explanation
Canvas is not an acceptable sterilization packaging material because it is not able to provide an effective barrier against microorganisms. Muslin, barrier cloth, and twills are commonly used materials for sterilization packaging as they are able to prevent the entry of microorganisms and maintain sterility. However, canvas is not suitable for this purpose as it may allow the passage of microorganisms, compromising the sterility of the packaged items.
3.
Count sheets:
Correct Answer
C. Provide a detailed list of trays contents
Explanation
The correct answer is "provide a detailed list of trays contents". This means that count sheets are used to list all the items or instruments that are included in a tray or pack used in operating rooms. It helps ensure that all the necessary instruments are present and accounted for during procedures. The count sheet provides a detailed inventory of the contents, allowing healthcare professionals to easily check and verify that everything is in order. It is an important tool for maintaining organization and efficiency in the operating room.
4.
When arranging paper/ plastic pouches in the sterilizer, the pouches should be arranged?
Correct Answer
A. Paper-to-plastic
Explanation
The correct answer is paper-to-plastic. When arranging paper/plastic pouches in the sterilizer, it is important to arrange them with the paper side facing the plastic side. This is because the paper side is more susceptible to damage from heat and moisture, so by placing it against the plastic, it is protected. Additionally, arranging them in this way ensures that the contents of the pouch are properly sterilized and protected during the sterilization process.
5.
The relative humidity of the central service prep and pack area should be:
Correct Answer
B. 30% to 60%
Explanation
The relative humidity of the central service prep and pack area should be between 30% and 60%. This range is considered optimal for maintaining the quality and safety of the products being prepared and packed in the area. Higher humidity levels can promote the growth of bacteria and mold, leading to spoilage of the products. On the other hand, lower humidity levels can cause the products to dry out and lose their quality. Therefore, maintaining a relative humidity between 30% and 60% ensures a suitable environment for the central service prep and pack area.
6.
Some plastics including formulations of spun-bonded polyolefin are intended for use solely in these sterilization processes.
Correct Answer
B. Ozone and hydrogen peroxide
Explanation
Some plastics, including formulations of spun-bonded polyolefin, are specifically designed to be used only in sterilization processes involving ozone and hydrogen peroxide. These sterilization methods are effective in killing microorganisms and ensuring a sterile environment. Other sterilization processes, such as steam or liquid sterilization, may not be suitable for these types of plastics and may cause damage or degradation to the material. Therefore, ozone and hydrogen peroxide sterilization is the recommended method for these specific plastics.
7.
When placing hinged instruments in an instrument tray:
Correct Answer
D. Unlock the handles and open the instruments
Explanation
When placing hinged instruments in an instrument tray, it is important to unlock the handles and open the instruments. This is because hinged instruments need to be opened for proper sterilization. If the handles are locked, it can prevent the instruments from being fully opened, which may hinder the sterilization process. Therefore, unlocking the handles and opening the instruments allows for thorough sterilization and prevents any potential damage.
8.
Gauze square is the wicking material of choice for instruments sets.
Correct Answer
B. False
Explanation
The statement is false because gauze square is not the preferred wicking material for instrument sets. There are other materials such as cotton or synthetic sponges that are commonly used for this purpose.
9.
When placing instruments in a peel pack, the tips should always face the plastic side of the pack.
Correct Answer
A. True
Explanation
When placing instruments in a peel pack, it is important to ensure that the tips of the instruments face the plastic side of the pack. This is because the plastic side provides a protective barrier, preventing the tips from puncturing through the pack and potentially causing damage or injury. Placing the tips towards the plastic side also makes it easier to identify and retrieve the instruments when needed, as they are more visible. Therefore, it is crucial to follow this practice to maintain the integrity of the peel pack and ensure the safety of the instruments.
10.
All rigid sterilization containers have tamper-evident seals.
Correct Answer
A. True
Explanation
Rigid sterilization containers are designed to securely hold and protect medical instruments during the sterilization process. Tamper-evident seals are an important feature of these containers as they provide visual indication if the container has been tampered with or opened before use. This ensures the sterility and safety of the instruments inside. Therefore, it can be concluded that all rigid sterilization containers have tamper-evident seals.
11.
Cellulose materials cannot be processed within ozone sterilizer.
Correct Answer
A. True
Explanation
Cellulose materials cannot be processed within an ozone sterilizer because ozone can react with the cellulose fibers and cause degradation or damage to the material. Ozone is a highly reactive gas that can break down organic compounds, and cellulose is a natural polymer found in plants. Therefore, exposing cellulose materials to ozone sterilization can result in the deterioration of the material, making it unsuitable for processing within an ozone sterilizer.
12.
Reusable textile packaging requires less labor than disposable packaging.
Correct Answer
B. False
Explanation
Reusuable textile packaging does not necessarily require less labor than disposable packaging. The labor required for both types of packaging depends on various factors such as the size and complexity of the packaging, the number of times it can be reused, and the specific process involved in its reuse. Therefore, it cannot be stated as a general rule that reusable textile packaging requires less labor than disposable packaging.
13.
Using latex tubing to protect delicate instrumentation is the process of choice for items to be steam-sterilized.
Correct Answer
B. False
Explanation
Using latex tubing to protect delicate instrumentation is not the process of choice for items to be steam-sterilized. Latex tubing is not suitable for steam sterilization as it can degrade and release harmful substances when exposed to high temperatures. Therefore, an alternative material or method should be used for items that require steam sterilization.
14.
While the outside of all instruments must be dry before sterilization it is important to ensure all lumens are kept moist for sterilization.
Correct Answer
B. False
Explanation
It is false that all lumens should be kept moist for sterilization. While the outside of instruments must be dry before sterilization, it is crucial to ensure that all lumens are completely dry as well. Moisture can interfere with the sterilization process and compromise its effectiveness. Therefore, it is important to thoroughly dry all lumens before sterilizing instruments.
