BPS Board-Certified Sterile Compounding Pharmacist
(BCSCP) Exam
Questions With Answers and Explanations
Question 1. During a quality review focused on light protection, which practice is most
appropriate?
A. Use clear tubing without evaluating photodegradation during administration.
B. Assume refrigeration replaces the need for light protection.
C. Place all light-sensitive CSPs under bright inspection lighting throughout storage.
D. Use a light-protective container or overwrap when stability data show that the preparation is photosensitive.
Correct Answer: D. Use a light-protective container or overwrap when stability data show that the
preparation is photosensitive.
Explanation: Use a light-protective container or overwrap when stability data show that the preparation is
photosensitive. Photolabile drugs can degrade when exposed to light even if other storage conditions are correct.
Temperature control and light protection address different degradation pathways. In practice, the pharmacist
should incorporate this principle into SOPs, competency assessment, verification, or release decisions as
applicable.
Question 2. A competency assessment includes a question about cosmetics and personal
items. Which response should be considered correct?
A. Permit earbuds and personal phones inside the PEC when disinfected once daily.
B. Allow powder cosmetics if they are applied before the shift.
C. Allow artificial nails if sterile gloves are worn.
D. Prohibit cosmetics and other particle-shedding or contamination-prone personal items from sterile
compounding areas as required.
Correct Answer: D. Prohibit cosmetics and other particle-shedding or contamination-prone
personal items from sterile compounding areas as required.
Explanation: Prohibit cosmetics and other particle-shedding or contamination-prone personal items from sterile
compounding areas as required. Cosmetics and personal items can shed particles, microorganisms, or residues
that challenge environmental control. Sterile gloves and room classification do not eliminate those upstream
contamination sources. In practice, the pharmacist should incorporate this principle into SOPs, competency
assessment, verification, or release decisions as applicable.
Question 3. Which action best demonstrates appropriate management of sterility testing
under USP <71>?
A. Release a failed sterility-test batch if visual inspection is normal.
B. Treat sterility testing as permission to ignore aseptic technique.
C. Use a validated compendial sterility test when sterility testing is required, recognizing that the test
supplements rather than replaces a controlled aseptic process.
D. Use one negative environmental plate as the sterility test for an entire batch.
Correct Answer: C. Use a validated compendial sterility test when sterility testing is required,
recognizing that the test supplements rather than replaces a controlled aseptic process.
Explanation: Use a validated compendial sterility test when sterility testing is required, recognizing that the test
supplements rather than replaces a controlled aseptic process. Sterility testing is a quality-control test with
defined methods and limitations. Because sampling cannot prove every unit is sterile, prevention through process
control remains fundamental. In practice, the pharmacist should incorporate this principle into SOPs, competency
assessment, verification, or release decisions as applicable.

Question 4. For an exam calculation, assume sodium chloride dissociates into two
osmotically active particles. What approximate osmolar contribution results from 50
mmol/L of sodium chloride?
A. 25 mOsm/L
B. 50 mOsm/L
C. 100 mOsm/L
D. 150 mOsm/L
Correct Answer: C. 100 mOsm/L
Explanation: Approximate osmolarity is 50 mmol/L × 2 particles = 100 mOsm/L. The calculation should be
completed with units carried through each step to reduce dimensional errors. Real formulations require
consideration of all solutes and nonideal behavior when clinically relevant. A pharmacist should independently
verify high-consequence calculations before the CSP is released.
Question 5. Which action best demonstrates appropriate management of evidence
hierarchy in literature evaluation?
A. Prefer an uncontrolled case report over a robust systematic review solely because it is newer.
B. Give greater weight to well-conducted, directly applicable studies and syntheses than to anecdote when
making a sterile-compounding practice decision.
C. Treat vendor advertising as equivalent to peer-reviewed evidence.
D. Ignore study population and methods if the conclusion supports current practice.
Correct Answer: B. Give greater weight to well-conducted, directly applicable studies and
syntheses than to anecdote when making a sterile-compounding practice decision.
Explanation: Give greater weight to well-conducted, directly applicable studies and syntheses than to anecdote
when making a sterile-compounding practice decision. Evidence quality depends on study design, conduct,
precision, consistency, and applicability. A newer or favorable conclusion is not automatically more trustworthy. In
practice, the pharmacist should incorporate this principle into SOPs, competency assessment, verification, or
release decisions as applicable.
Question 6. An inspector asks how the pharmacy handles change control. Which response
best reflects sound sterile-compounding practice?
A. Treat all software upgrades as administrative changes with no quality impact.
B. Implement a new container before compatibility assessment and document it later.
C. Allow staff to modify validated settings whenever workflow improves.
D. Use formal change control to evaluate, approve, implement, and verify changes to equipment, facilities,
formulations, software, or procedures that may affect quality.
Correct Answer: D. Use formal change control to evaluate, approve, implement, and verify
changes to equipment, facilities, formulations, software, or procedures that may affect quality.
Explanation: Use formal change control to evaluate, approve, implement, and verify changes to equipment,
facilities, formulations, software, or procedures that may affect quality. Controlled change prevents unintended
effects on validated processes and product quality. Even apparently minor changes can alter calculations, airflow,
compatibility, or traceability. In practice, the pharmacist should incorporate this principle into SOPs, competency
assessment, verification, or release decisions as applicable.

Question 7. Which action best demonstrates appropriate management of lot traceability?
A. Record lot numbers only for hazardous drugs.
B. Record only the wholesaler name because lot numbers are unnecessary after release.
C. Discard lot information once a CSP passes visual inspection.
D. Record component lot numbers so a finished CSP can be traced back to the specific source materials used.
Correct Answer: D. Record component lot numbers so a finished CSP can be traced back to the
specific source materials used.
Explanation: Record component lot numbers so a finished CSP can be traced back to the specific source materials
used. Lot traceability is essential for investigations, recalls, and reproducibility. Supplier identity and visual
inspection cannot replace the ability to link a preparation to exact source lots. In practice, the pharmacist should
incorporate this principle into SOPs, competency assessment, verification, or release decisions as applicable.
Question 8. A pharmacist is precepting a new sterile-compounding team member about
workflow sequencing. Which instruction is correct?
A. Move used supplies back across disinfected critical work areas.
B. Perform label printing and unrelated phone calls in the PEC during compounding.
C. Carry opened shipping cartons into the ISO Class 5 work zone for convenience.
D. Organize the compounding workflow to minimize unnecessary movement, interruptions, and crossover of
dirty and clean materials.
Correct Answer: D. Organize the compounding workflow to minimize unnecessary movement,
interruptions, and crossover of dirty and clean materials.
Explanation: Organize the compounding workflow to minimize unnecessary movement, interruptions, and
crossover of dirty and clean materials. A controlled workflow reduces particulate generation, touch contamination,
and mix-ups. The PEC should be reserved for aseptic tasks with materials arranged to preserve clean airflow. In
practice, the pharmacist should incorporate this principle into SOPs, competency assessment, verification, or
release decisions as applicable.
Question 9. A pharmacist is precepting a new sterile-compounding team member about
ceiling-mounted HEPA filtration. Which instruction is correct?
A. Design classified room supply so HEPA-filtered air is delivered in a way that minimizes post-filter
contamination and supports certification.
B. Position return grilles so they intentionally short-circuit supply air before it reaches the work zone.
C. Rely on a portable fan to replace HEPA supply air.
D. Place the only HEPA filter upstream of leaky ductwork and assume the room remains protected.
Correct Answer: A. Design classified room supply so HEPA-filtered air is delivered in a way that
minimizes post-filter contamination and supports certification.
Explanation: Design classified room supply so HEPA-filtered air is delivered in a way that minimizes post-filter
contamination and supports certification. HEPA supply design should protect the air after filtration and create
effective room sweeping. Poor duct integrity or short-circuit airflow can defeat filtration performance. In practice,
the pharmacist should incorporate this principle into SOPs, competency assessment, verification, or release
decisions as applicable.

Question 10. An inspector asks how the pharmacy handles catheter-related bloodstream
infection. Which response best reflects sound sterile-compounding practice?
A. Use environmental surface cultures as the sole test for bloodstream infection.
B. Replace the CSP label and continue the same line without clinical evaluation.
C. Assume a clear infusion bag rules out catheter infection.
D. Evaluate fever, chills, hemodynamic change, catheter-site findings, and appropriate cultures when a
catheter-related bloodstream infection is suspected.
Correct Answer: D. Evaluate fever, chills, hemodynamic change, catheter-site findings, and
appropriate cultures when a catheter-related bloodstream infection is suspected.
Explanation: Evaluate fever, chills, hemodynamic change, catheter-site findings, and appropriate cultures when a
catheter-related bloodstream infection is suspected. Catheter-related infection is a patient complication that
requires clinical and microbiologic assessment. Product appearance and environmental data alone cannot
establish or exclude bloodstream infection. In practice, the pharmacist should incorporate this principle into SOPs,
competency assessment, verification, or release decisions as applicable.
Question 11. A sterile compounding supervisor is revising an SOP section on vesicant
administration planning. Which provision should be included?
A. Treat all peripheral and central access devices as equivalent for vesicant administration.
B. Increase vesicant concentration to shorten administration without evaluating tissue-injury risk.
C. Select and communicate an administration route and vascular access plan appropriate for vesicant risk,
concentration, and duration.
D. Ignore line patency if blood return was documented earlier in the day.
Correct Answer: C. Select and communicate an administration route and vascular access plan
appropriate for vesicant risk, concentration, and duration.
Explanation: Select and communicate an administration route and vascular access plan appropriate for vesicant
risk, concentration, and duration. Vesicants can cause severe tissue injury after extravasation, so route and
device selection matter. Compounding decisions should support safe administration, not merely dose delivery. In
practice, the pharmacist should incorporate this principle into SOPs, competency assessment, verification, or
release decisions as applicable.
Question 12. Which statement about HEPA filter integrity is most accurate for a pharmacist
responsible for compounded sterile preparations?
A. Delay action until environmental cultures become positive.
B. Use particle counts alone to prove a visibly damaged filter is intact.
C. Cover a failed area with tape and continue indefinitely without retesting.
D. Test HEPA filters for integrity and repair or replace filters that fail required leak testing before relying on them
for classified air.
Correct Answer: D. Test HEPA filters for integrity and repair or replace filters that fail required
leak testing before relying on them for classified air.
Explanation: Test HEPA filters for integrity and repair or replace filters that fail required leak testing before relying
on them for classified air. A leak can bypass filtration and deliver contaminated air directly into a controlled
environment. Integrity testing addresses the filter barrier itself and should not be replaced by indirect evidence. In
practice, the pharmacist should incorporate this principle into SOPs, competency assessment, verification, or
release decisions as applicable.
