When re-entering the buffer area, you can wear the same hair cover, beard cover, face mask and shoe covers that you took off when you exited the buffer area?

True
False

Correct Answer

A. False

Explanation

When re-entering the buffer area, it is not advisable to wear the same hair cover, beard cover, face mask, and shoe covers that were taken off when exiting the buffer area. This is because these items may have come into contact with contaminants or pathogens, and reusing them could potentially introduce those contaminants back into the buffer area. It is best practice to use fresh, clean protective gear when re-entering the buffer area to maintain a sterile and safe environment.

A person who has a sunburn cannot work within the ISO class 5 or ISO class 7 environment until their burn has healed.

True
False

Correct Answer

A. True

Explanation

Sunburned skin is damaged and more sensitive to irritants and contaminants. ISO class 5 and ISO class 7 environments have strict cleanliness requirements, and any open wounds or damaged skin can increase the risk of infection and compromise the integrity of the controlled environment. Therefore, it is necessary for a person with a sunburn to wait until their burn has healed before working in such environments to maintain the cleanliness and safety standards.

Prior to entering the cleanroom, what must you remove before entering?

Socks and shoes
Gown and shoe covers
Hair cover and face mask
Jewelry and make up

Correct Answer

A. Jewelry and make up

Explanation

Before entering the cleanroom, it is necessary to remove jewelry and make up. This is because jewelry and make up can harbor bacteria, particles, or contaminants that can contaminate the cleanroom environment. Removing jewelry and make up helps to maintain the cleanliness and integrity of the cleanroom, ensuring that no foreign substances are introduced into the controlled environment.

What ISO class are low-risk level CSP’s compounded in?

ISO Class 8
ISO Class 7
ISO Class 6
ISO Class 5

Correct Answer

A. ISO Class 5

Explanation

Low-risk level CSP's are compounded in an ISO Class 5 environment. This means that the environment has a controlled level of particulate contamination, with a maximum of 3,520 particles per cubic meter. This class of environment is suitable for compounding CSP's that have a low risk of microbial contamination.

Who do the USP chapter <797> standards apply?

Hospitals, healthcare institutions, pharmacies
Physicians and nurses
Pharmacists and pharmacy technicians
All of the above

Correct Answer

A. All of the above

Explanation

The USP chapter standards apply to hospitals, healthcare institutions, pharmacies, physicians, nurses, pharmacists, and pharmacy technicians. These standards are put in place to ensure the safe handling and preparation of sterile products, including medications, to minimize the risk of contamination and ensure patient safety.

7.

For a CSP to be considered for medium risk level compounding, only two sterile products must be used.

True
False

Correct Answer

A. False

Explanation

The statement is false because for a CSP (Compounded Sterile Preparation) to be considered for medium risk level compounding, it must meet certain criteria, including the use of no more than three sterile products. Therefore, the statement that only two sterile products must be used is incorrect.

8.

How often should the ISO 5 Engineering Control (BSC, LAFW, CAI) be cleaned and disinfected?

At the start of each shift
Daily
Weekly
Monthly

Correct Answer

A. At the start of each shift

Explanation

The ISO 5 Engineering Control (BSC, LAFW, CAI) should be cleaned and disinfected at the start of each shift to ensure a clean and sterile environment for work. This regular cleaning and disinfection routine helps to maintain the effectiveness of the engineering control and prevent any contamination or buildup of particles that could compromise the quality of the work being done.

What could cause potential harm to patients if compounding is not done aseptically?

Microbial, chemical and physical contamination
Variability in the intended strength of ingredients
Incorrect types and qualities of ingredients in CSPs
All of the above

Correct Answer

A. All of the above

Explanation

If compounding is not done aseptically, it can lead to potential harm to patients due to microbial, chemical, and physical contamination. This means that harmful microorganisms, unwanted chemicals, or foreign particles can be introduced into the compounded sterile preparations (CSPs), which can cause infections, allergic reactions, or other adverse effects in patients. Additionally, the variability in the intended strength of ingredients and the use of incorrect types and qualities of ingredients can further contribute to patient harm by leading to ineffective or unsafe medications. Therefore, all of the mentioned factors can cause potential harm if compounding is not done aseptically.

Non-hazardous buffer areas require _ and _ inches of water column for the pressure?

Positive pressure and ≤ 0.02
Negative pressure and ≤ 0.02
Positive pressure and 0.02 - 0.05
Negative pressure and 0.02 – 0.05

Correct Answer

A. Positive pressure and 0.02 - 0.05

Explanation

Non-hazardous buffer areas require positive pressure and a range of 0.02 - 0.05 inches of water column for the pressure. This means that there should be a slight excess of pressure inside the buffer area compared to the surrounding environment, and the pressure should be within the specified range. This ensures that any potential contaminants or hazardous substances are contained within the buffer area and do not escape into the surrounding areas.

11.

How many total room air changes per hour (ACpH) are required for an ISO 7 (buffer area) environment?

No less than 30
No less than 20
No less than 15
No less than 5

Correct Answer

A. No less than 30

Explanation

An ISO 7 (buffer area) environment requires a certain number of room air changes per hour (ACPH) to maintain air quality. The correct answer states that no less than 30 ACPH are required for this type of environment. This means that the minimum number of air changes per hour should be 30 in order to ensure proper ventilation and maintain the desired air quality standards.

For medium-risk conditions, how long can CSPs be stored at refrigeration temperatures?

≤ 48 Hours
≤ 3 days
≤ 9 days
≤ 45 days

Correct Answer

A. ≤ 9 days

Explanation

CSPs (Compounded Sterile Preparations) can be stored at refrigeration temperatures for a maximum of 9 days in medium-risk conditions. This means that after compounding the sterile preparations, they can be kept in a refrigerated environment for up to 9 days before they expire or become unsafe for use. It is important to adhere to these storage guidelines to ensure the safety and efficacy of the CSPs.

13.

CSPs that have been weighed and mixed in air quality worse than ISO Class 7 conditions are considered to be what risk level?

Low Risk
Medium Risk
High Risk
All of the Above

Correct Answer

A. High Risk

Explanation

CSPs that have been weighed and mixed in air quality worse than ISO Class 7 conditions are considered to be high risk. This implies that the air quality during the weighing and mixing process is not up to the required standard, which increases the chances of contamination or impurities in the CSPs. Therefore, these CSPs pose a higher risk to patients or individuals who may consume or use them.
