2.

Sterilized packages may be jeopardized due to storage practices.

True
False

Correct Answer

A. True

Explanation

Sterilized packages can indeed be jeopardized due to improper storage practices. If the packages are not stored in a clean and controlled environment, they may be exposed to contaminants that can compromise their sterility. For example, if the packages are stored in an area with high humidity or temperature fluctuations, it can lead to the growth of bacteria or other microorganisms. Additionally, if the packages are not properly sealed or protected, they may be susceptible to damage or tampering, which can also compromise their sterility. Therefore, it is important to follow appropriate storage practices to ensure the integrity of sterilized packages.

The relative humidity of the Central Service sterile storage area should be

Less than 70%.
Less than 60%.
Less than 50%.
Less than 35%.

Correct Answer

A. Less than 70%.

Explanation

The correct answer is less than 70% because maintaining a relative humidity level below 70% in the Central Service sterile storage area is important to prevent the growth of mold and bacteria. Higher humidity levels can create a suitable environment for microbial growth, which can compromise the sterility of stored items and pose a risk to patients' health. Therefore, it is crucial to maintain a humidity level below 70% to ensure the integrity and safety of the sterile storage area.

Sterile trays should

Not be touched until they are properly cooled.
Be lifted not dragged off the sterilizer cart.
Be checked to be sure the chemical indicators have turned the appropriate color.
All the above.

Correct Answer

A. All the above.

Explanation

The correct answer is "all the above" because sterile trays should not be touched until they are properly cooled to prevent contamination, they should be lifted and not dragged off the sterilizer cart to avoid damaging the contents, and they should be checked to ensure that the chemical indicators have turned the appropriate color to confirm sterilization.

5.

Wrapped trays should not be stacked because

The tray contents may be damaged.
It can cause holes in the wrapper of the bottom tray.
It will cause the shelving to bend.
They will be more difficult to rotate.

Correct Answer

A. It can cause holes in the wrapper of the bottom tray.

Explanation

Stacking wrapped trays can cause holes in the wrapper of the bottom tray. When trays are stacked on top of each other, the weight and pressure from the upper trays can puncture the wrapper of the tray at the bottom. This can lead to damage or contamination of the contents inside the tray, compromising their quality and safety. Therefore, it is important to avoid stacking wrapped trays to prevent any potential damage to the packaging and its contents.

6.

The type of shelving that leaves packaging the most vulnerable is

Open.
Closed.
Semi closed.
Tracked.

Correct Answer

A. Open.

Explanation

Open shelving leaves packaging the most vulnerable because it does not provide any physical barriers or protection for the items on the shelves. This means that the packaging is exposed to various elements such as dust, moisture, and potential damage from handling. Additionally, open shelving makes it easier for items to be accidentally knocked off or misplaced, further increasing the vulnerability of the packaging.

Trays which overhang shelving

Can become contaminated.
Are ok for rigid containers, but not for flat wrapped trays.
Is the appropriate way to store trays as it allows for the use of proper body mechanics when lifting heavy trays.
None of the above.

Correct Answer

A. Can become contaminated.

Explanation

The correct answer is "can become contaminated." This is because when trays overhang shelving, there is a risk of them coming into contact with dirt, dust, or other contaminants, which can contaminate the food or items placed on the trays. It is important to ensure that trays are properly stored and protected to maintain hygiene and prevent contamination.

The bottom shelf of any sterile storage system should be

Solid and eight to 10 inches from the floor.
Solid and two to four inches from the floor.
Cleaned weekly.
Wire and eight to 10 inches from the floor.

Correct Answer

A. Solid and eight to 10 inches from the floor.

Explanation

The correct answer is "solid and eight to 10 inches from the floor." This is because the bottom shelf of a sterile storage system needs to be solid in order to prevent any contamination from the floor. Additionally, it should be positioned eight to 10 inches from the floor to ensure proper air circulation and prevent dust and dirt from settling on the stored items.

The sterile storage process starts

When items are received in the decontamination area.
After items are sterilized and cooled.
When the sterilizer door is opened.
When items are placed into the sterilizer.

Correct Answer

A. When the sterilizer door is opened.

Explanation

The correct answer is when the sterilizer door is opened. This is because the sterile storage process begins once the sterilizer door is opened, indicating that the sterilization and cooling of the items have been completed. This step ensures that the items remain in a sterile environment until they are needed for use. The opening of the sterilizer door marks the transition from the sterilization phase to the storage phase of the process.

The shelving system of choice for the sterile storage area is

Closed.
Semi closed.
Open.
Tracked.

Correct Answer

A. Closed.

Explanation

The correct answer is "closed". In a sterile storage area, it is crucial to prevent any contamination or exposure to bacteria or other pathogens. A closed shelving system helps in achieving this by providing a barrier that keeps the stored items protected and isolated from the surrounding environment. It ensures that the items remain sterile and reduces the risk of contamination.

Sterile storage areas should

Have positive airflow and at least 10 air exchanges per hour.
Have positive airflow and at least four air exchanges per hour.
Have negative airflow and at least 10 air exchanges per hour.
Have negative airflow and at least four air exchanges per hour.

Correct Answer

A. Have positive airflow and at least 10 air exchanges per hour.

Explanation

Positive airflow in sterile storage areas helps prevent contaminants from entering the space. The higher air exchange rate ensures that the air is continuously filtered and refreshed, maintaining a sterile environment for storing medical supplies and equipment.

Outside shipping containers

Should be removed prior to placing the items in storage.
May be stored in the sterile storage area as long as they are not stored near the in-house sterilized items.
Make good storage containers to help keep items from falling from the shelves.
All the above.

Correct Answer

A. Should be removed prior to placing the items in storage.

Explanation

The correct answer is "should be removed prior to placing the items in storage." This answer suggests that outside shipping containers should not be stored along with the items in storage. It implies that the containers may take up unnecessary space or hinder the organization of the storage area. Removing the shipping containers before placing the items in storage would ensure a more efficient use of the storage space.

Temperatures in a sterile storage area should be 64° to 75° F.

True
False

Correct Answer

A. False

Explanation

The statement is false because temperatures in a sterile storage area should be kept between 68°F to 73°F. This temperature range helps to prevent the growth of bacteria and maintain the sterility of the stored items. If the temperature falls below or exceeds this range, it can compromise the integrity of the sterile items and increase the risk of contamination.

True
False

Correct Answer

A. False

Explanation

The given statement is false. Event-related shelf life does not mean that items are safe until opened for use. Event-related shelf life refers to the duration for which items can be safely stored and used before they expire or become unsafe, regardless of whether they have been opened or not.
