A. Heparin
B. Multivitamin tablet
C. Topical moisturizer
D. Calcium carbonate chewable tablet
Correct Answer: A. Heparin
,Rationale: Heparin is considered a high-alert medication because errors involving it can result in serious patient harm. Other examples relevant
to sterile compounding include insulin, concentrated electrolytes, and certain chemotherapy agents. High-alert medications require careful
verification, preparation, labeling, and handling.
6. What is the primary concern when compounding a preparation containing a narrow therapeutic index medication?
A. Minor dose variations may result in significant clinical consequences
B. The medication cannot be compounded
C. The medication is always unstable
D. The medication must always be refrigerated
Correct Answer: A. Minor dose variations may result in significant clinical consequences
Rationale: A narrow therapeutic index means the difference between an effective dose and a toxic dose can be relatively small. Accurate
calculations, measurement, preparation, verification, labeling, and appropriate quality-control procedures are therefore particularly important.
7. Which reference would provide authoritative information about a manufacturer's specific preparation, storage, or stability
instructions?
A. Package insert
B. Social media post
C. Personal notebook
D. Unverified internet discussion
Correct Answer: A. Package insert

conditions, compatibility, stability, and other product-specific information. Technical references should be selected based on the information
needed and their authority.
8. Why is compatibility between CSP components important?
A. Incompatibility can cause precipitation, degradation, or other physical or chemical changes
B. Compatibility only affects the label appearance
C. Compatibility determines the technician's work schedule
D. Compatibility has no relationship to patient safety
Correct Answer: A. Incompatibility can cause precipitation, degradation, or other physical or chemical changes
Rationale: Components of a CSP must be compatible with one another and with the container-closure system. Incompatibility can cause visible
precipitation, color changes, loss of potency, container damage, or other changes that may compromise the preparation.
9. A solution develops unexpected particles after two medications are mixed. What should the technician do?
A. Shake the solution until the particles disappear
B. Filter it automatically and dispense it
C. Stop the process and notify the pharmacist according to procedure
D. Ignore the particles if the final volume is correct
Correct Answer: C. Stop the process and notify the pharmacist according to procedure
Rationale: Unexpected particles may indicate incompatibility, precipitation, contamination, or degradation. The preparation should not be
assumed to be safe merely because the volume or calculated dose is correct. Investigation and pharmacist assessment are required.
10. Which factor can affect the stability of a compounded sterile preparation?
A. Temperature
B. Technician's preferred handwriting style
C. Color of the compounding room
D. Time of day alone
Correct Answer: A. Temperature
Rationale: Temperature can significantly affect chemical and physical stability. Other important factors include concentration, container type,
light exposure, pH, storage conditions, agitation, and compatibility of components.
,11. What is a beyond-use date (BUD)?
A. The date after which a CSP should not be used under the conditions specified
B. The date the medication was originally manufactured
C. The date a prescription was written
D. The date a technician completed training
Correct Answer: A. The date after which a CSP should not be used under the conditions specified
Rationale: A BUD establishes the time beyond which a compounded preparation should not be used, based on applicable standards, stability
information, preparation conditions, storage conditions, and other relevant factors. It is not necessarily the same as the manufacturer's expiration
date.
12. Which factor is particularly important when determining an appropriate BUD?
A. Sterility and stability information
B. Technician preference
C. Label font size
D. Patient's favorite color
Correct Answer: A. Sterility and stability information
Rationale: BUD assignment requires consideration of the preparation's microbial risk, storage conditions, chemical and physical stability,
preparation method, and applicable standards. The BUD should be supported by appropriate authoritative information.
13. What is the primary purpose of a primary engineering control (PEC)?
A. Provide an environment that helps protect the CSP from contamination during critical compounding activities
B. Store finished prescriptions indefinitely
C. Replace hand hygiene
D. Eliminate the need for garbing
Correct Answer: A. Provide an environment that helps protect the CSP from contamination during critical compounding activities
Rationale: A PEC provides controlled airflow and an appropriate environment for critical sterile compounding activities. Examples include
biological safety cabinets, laminar airflow workbenches, and other qualified engineering controls depending on the type of preparation.
14. Which airflow pattern is characteristic of a horizontal laminar airflow workbench?
A. HEPA-filtered air moves horizontally toward the operator
B. Air moves directly from the operator toward the critical site
C. Unfiltered room air moves toward the preparation
D. Air moves randomly without filtration
Correct Answer: A. HEPA-filtered air moves horizontally toward the operator
Rationale: In a horizontal LAFW, HEPA-filtered air moves from the rear of the work zone toward the front. The airflow provides an ISO-
classified environment for appropriate nonhazardous sterile compounding activities. Hazardous-drug compounding requires appropriate
containment equipment rather than a conventional horizontal LAFW.
15. What is the primary function of a HEPA filter in a PEC?
A. Remove airborne particles from the air supplied to the work area
B. Sterilize medication chemically
C. Remove dissolved contaminants from IV solutions
D. Increase room temperature
Correct Answer: A. Remove airborne particles from the air supplied to the work area
Rationale: High-efficiency particulate air filtration removes a very high proportion of particles from the air stream. The resulting filtered airflow
helps maintain the required environmental conditions for sterile compounding.
16. Why should objects not obstruct first air within a PEC?
A. Obstruction can prevent HEPA-filtered air from directly reaching critical sites
B. Obstruction improves sterility
, C. Obstruction increases medication potency
D. Obstruction reduces the need for cleaning
Correct Answer: A. Obstruction can prevent HEPA-filtered air from directly reaching critical sites
Rationale: First air is the HEPA-filtered air that reaches critical sites without encountering an obstruction. Blocking first air can allow particles
from less controlled areas to reach sterile components or critical sites, increasing contamination risk.
17. Which item represents a critical site during sterile compounding?
A. Sterile syringe tip
B. Exterior of the technician's gown
C. Outside of the compounding room
D. Floor beneath the PEC
Correct Answer: A. Sterile syringe tip
Rationale: Critical sites include sterile surfaces that must remain sterile to protect the CSP, such as syringe tips, needle hubs, exposed vial
stoppers, and sterile connection points. These areas should remain protected from contamination throughout the compounding process.
18. What is the primary purpose of hand hygiene before sterile compounding?
A. Reduce microorganisms on the hands before donning sterile compounding gloves
B. Remove medication labels
C. Increase glove size
D. Replace environmental cleaning
Correct Answer: A. Reduce microorganisms on the hands before donning sterile compounding gloves
Rationale: Proper hand hygiene reduces microbial contamination before garbing and gloving. Gloves provide an additional barrier but do not
replace hand hygiene.
19. A technician touches a contaminated surface while wearing sterile gloves. What is the appropriate response?
A. Continue because the gloves still appear clean
B. Sanitize or replace the gloves according to the applicable procedure before resuming critical work
C. Wipe the gloves on the gown
D. Ignore the contact if no visible dirt is present
Correct Answer: B. Sanitize or replace the gloves according to the applicable procedure before resuming critical work
Rationale: Contact with a nonsterile or contaminated surface can compromise glove cleanliness. The technician should follow the facility's
approved procedure for disinfecting or replacing gloves before continuing sterile compounding.
20. Why should sterile gloves be disinfected with an appropriate sterile alcohol solution during compounding when required?
A. To reduce microbial contamination on the glove surface
B. To sterilize the entire PEC
C. To replace handwashing
D. To increase glove thickness
Correct Answer: A. To reduce microbial contamination on the glove surface
Rationale: Glove disinfection helps reduce microorganisms introduced onto the glove surface during compounding activities. Proper technique,
adequate drying, and appropriate frequency are essential.
21. Which action presents the greatest risk of contaminating a critical site?
A. Blocking first air with a nonsterile object
B. Keeping sterile components within the appropriate airflow
C. Maintaining appropriate aseptic technique
D. Disinfecting work surfaces according to procedure
Correct Answer: A. Blocking first air with a nonsterile object
