Introduction
This comprehensive examination is designed to prepare pharmacy
candidates for the Pharmacy Examining Board of Canada (PEBC)
qualifying examinations by rigorously testing core professional
competencies. The assessment evaluates vital knowledge spanning
foundational pharmaceutical sciences, clinical pharmacotherapy,
Canadian pharmacy law, ethical decision-making, and safe medication
management. Featuring a blend of direct knowledge recall and complex
scenario-based clinical cases, the test emphasizes real-world application,
interprofessional collaboration, and patient-centered decision-making in
pharmacy practice. Candidates must demonstrate critical analytical skills
to navigate intricate drug therapy problems, ensure regulatory
compliance, and optimize therapeutic outcomes safely and effectively
across diverse clinical settings.
Question 1
,A 58-year-old male presents to the community pharmacy with a new
prescription for warfarin. He has a history of atrial fibrillation and recently
started taking amiodarone for rhythm control. Which of the following best
describes the expected drug interaction between warfarin and
amiodarone?
A. Amiodarone induces CYP2C9, leading to decreased warfarin plasma
concentrations and subtherapeutic INR.
B. Amiodarone inhibits CYP2C9 and CYP3A4, leading to increased
warfarin plasma concentrations and elevated bleeding risk.
C. Amiodarone displaces warfarin from plasma protein binding sites,
permanently lowering total body clearance.
D. Amiodarone decreases the absorption of oral warfarin in the
gastrointestinal tract via P-glycoprotein inhibition.
🟢 B. Amiodarone inhibits CYP2C9 and CYP3A4, leading to increased
warfarin plasma concentrations and elevated bleeding risk.
🔴 Explanation: Amiodarone is a well-known inhibitor of hepatic
cytochrome P450 enzymes, specifically CYP2C9 and CYP3A4, which are
responsible for the metabolism of the S- and R-enantiomers of warfarin.
Co-administration results in reduced clearance of warfarin, accumulation
of the drug, and a significant increase in INR, elevating the risk of
bleeding.
Question 2
Under the Controlled Drugs and Substances Act (CDSA) in Canada,
which of the following schedules contains cannabis and its derivatives
prior to legalization updates, or specifically outlines strict restrictions for
potent narcotics such as morphine and hydromorphone?
A. Schedule I
B. Schedule II
C. Schedule III
D. Schedule IV
🟢 A. Schedule I
🔴 Explanation: Under the Controlled Drugs and Substances Act (CDSA)
in Canada, Schedule I includes the most tightly controlled substances
with high potential for abuse and dependence, such as opium, heroin,
cocaine, and synthetic opioids like morphine, hydromorphone, and
fentanyl.
Question 3
,A patient weighing 70 kg is prescribed gentamicin with a target peak
concentration of 8 mg/L and a trough concentration of less than 1 mg/L.
Using pharmacokinetic principles, which parameter is primarily used to
calculate the individual maintenance dosing interval and dose
adjustments for aminoglycosides in renal impairment?
A. Volume of distribution
B. Creatinine clearance
C. Bioavailability
D. Hepatic extraction ratio
🟢 B. Creatinine clearance
🔴 Explanation: Aminoglycosides such as gentamicin are primarily
eliminated unchanged by the kidneys via glomerular filtration. Therefore,
renal function—quantified using creatinine clearance or estimated
glomerular filtration rate (eGFR)—is the primary pharmacokinetic
parameter utilized to adjust both the dose and the interval to prevent
toxicity.
Question 4
A pharmacist receives a prescription for a pediatric patient specifying an
extemporaneous suspension that is not commercially available. What is
the primary reference standard in Canada that provides standardized
formulas for compounding sterile and non-sterile preparations?
A. Compounding Today Compendium
B. The Compounding Pharmacists of Canada Manual
C. Health Canada Guidelines for Extemporaneous Formulations
D. The Compounding Compendium / USP-NF and local NAPRA
standards
🟢 D. The Compounding Compendium / USP-NF and local NAPRA
standards
🔴 Explanation: Canadian pharmacy practice follows National
Association of Pharmacy Regulatory Authorities (NAPRA) Model
Standards for Pharmacy Compounding, which incorporate standards
derived from references such as the United States Pharmacopeia (USP)
to ensure safety and quality in non-sterile and sterile preparations.
Question 5
A 45-year-old female presents with acute migraine headaches. She has a
past medical history of uncontrolled hypertension and ischemic heart
, disease. Which of the following acute migraine therapies is
contraindicated due to her cardiovascular comorbidities?
A. Sumatriptan
B. Acetaminophen with codeine
C. Naproxen sodium
D. Metoclopramide
🟢 A. Sumatriptan
🔴 Explanation: Triptans, such as sumatriptan, are selective serotonin
receptor agonists that cause vasoconstriction. They are contraindicated in
patients with ischemic heart disease, history of stroke, uncontrolled
hypertension, or peripheral vascular disease due to the risk of coronary
vasospasm and myocardial ischemia.
Question 6
When conducting a medication reconciliation in a hospital setting for an
elderly patient admitted from a long-term care facility, which step
represents the primary goal of the reconciliation process?
A. Reducing the overall cost of drug therapy for the institution
B. Ensuring complete, accurate, and unbroken communication of
medication orders across transitions of care
C. Eliminating all over-the-counter and herbal products permanently
D. Transitioning the patient exclusively to generic formulations
🟢 B. Ensuring complete, accurate, and unbroken communication of
medication orders across transitions of care
🔴 Explanation: Medication reconciliation is a formal process designed to
create the most accurate list possible of all medications a patient is taking
and compare it with the admission, transfer, or discharge orders to avoid
discrepancies, omission, duplication, or drug interactions across care
transitions.
Question 7
A community pharmacist notices a systematic trend of near-miss events
involving look-alike, sound-alike (LASA) medications stored adjacently on
dispensary shelves. Which proactive quality improvement strategy should
be implemented first?
A. Punishing staff members responsible for dispensing errors
B. Separating the LASA drugs using shelf dividers, tall-man lettering, and
