PEBC PHARMACIST EVALUATING EXAM | ALL
QUESTIONS AND ANSWERS | A+ GRADED |
COMPREHENSIVE EXAM GUIDE 2026/2027
1. A patient with newly diagnosed hypertension is prescribed hydrochlorothiazide. Which
counseling point is most appropriate regarding the medication's expected effect?
A. It should immediately lower blood pressure within minutes
B. It may increase urinary frequency, particularly when therapy is initiated
C. It should be taken only when blood pressure is elevated
D. It commonly causes severe hypoglycemia in patients without diabetes
Answer: B
Rationale: Hydrochlorothiazide promotes renal sodium and water excretion and may increase
urination, especially early in therapy. Patients should understand that it is intended for
regular use rather than as-needed treatment.
2. A patient taking warfarin presents with an INR significantly above the therapeutic range
and reports new spontaneous nosebleeds. What is the pharmacist's priority?
A. Recommend an additional dose of warfarin
B. Advise the patient to double the next dose if bleeding stops
C. Assess the severity of bleeding and arrange urgent clinical evaluation
D. Recommend increasing dietary vitamin K immediately without further assessment
Answer: C
Rationale: A supratherapeutic INR accompanied by active bleeding requires prompt
assessment and appropriate medical management. The pharmacist should not independently
normalize the INR through unsupervised dosing changes.
3. Which pharmacokinetic parameter most directly describes the fraction of an
administered dose that reaches systemic circulation unchanged?
A. Bioavailability
B. Clearance
C. Volume of distribution
D. Half-life
Answer: A
Rationale: Bioavailability is the fraction of an administered dose that reaches systemic
circulation in unchanged form. Intravenous administration is considered to have complete
bioavailability.
,4. A patient with asthma uses a salbutamol inhaler several times every day and reports
increasing nighttime symptoms. What is the most appropriate interpretation?
A. The patient's asthma is adequately controlled
B. Frequent salbutamol use confirms treatment success
C. The patient should permanently discontinue all inhaled therapy
D. Frequent reliever use suggests inadequate control and warrants reassessment of controller
therapy
Answer: D
Rationale: Increasing reliance on a short-acting beta2-agonist and nighttime symptoms
indicate poor asthma control. The patient should be reassessed, including adherence,
technique, triggers, and the need for appropriate controller therapy.
5. Which statement best describes the mechanism of action of angiotensin-converting
enzyme inhibitors?
A. They directly stimulate beta1 receptors
B. They inhibit conversion of angiotensin I to angiotensin II
C. They block calcium channels in vascular smooth muscle
D. They increase aldosterone secretion
Answer: B
Rationale: ACE inhibitors reduce formation of angiotensin II, resulting in reduced
vasoconstriction and aldosterone-mediated sodium retention. They can also increase
bradykinin, contributing to cough and, rarely, angioedema.
6. A patient taking metformin is scheduled for a procedure involving iodinated contrast.
Which factor is most important before deciding whether metformin should be temporarily
withheld?
A. The patient's height
B. The patient's blood group
C. Renal function and the clinical circumstances surrounding contrast administration
D. Whether the patient takes the medication with breakfast
Answer: C
Rationale: Renal function is central to assessing the risk associated with metformin around
iodinated contrast exposure. Current recommendations depend on renal function, the type of
imaging, and the patient's risk of acute kidney injury.
7. Which adverse effect is particularly associated with opioid analgesics?
A. Respiratory depression
B. Severe hyperthyroidism
C. Increased bowel motility
D. Profound hypertension in most patients
,Answer: A
Rationale: Opioids can suppress respiratory drive, especially at excessive doses or when
combined with other central nervous system depressants. Constipation, sedation, nausea, and
respiratory depression are important adverse effects.
8. A patient reports that an enteric-coated tablet is difficult to swallow. Which counseling
recommendation is generally appropriate?
A. Crush the tablet and mix it with hot water
B. Split the tablet regardless of its formulation
C. Chew the tablet thoroughly before swallowing
D. Do not crush or chew it; determine whether an appropriate alternative formulation is
available
Answer: D
Rationale: Enteric-coated products are designed to resist dissolution in the stomach. Crushing
or chewing may destroy the intended release characteristics and can alter drug absorption or
tolerability.
9. Which laboratory parameter is most directly used to monitor the anticoagulant effect of
warfarin?
A. Serum creatinine
B. INR
C. Serum sodium
D. Activated clotting time in routine outpatient therapy
Answer: B
Rationale: The international normalized ratio standardizes prothrombin time and is used
routinely to monitor warfarin therapy and guide dosing.
10. A patient taking an antibiotic develops severe watery diarrhea several days after
treatment begins. Which concern should the pharmacist prioritize?
A. Antibiotic-associated Clostridioides difficile infection
B. Immediate development of iron deficiency
C. Expected harmless gastrointestinal adaptation
D. Acute vitamin D toxicity
Answer: A
Rationale: Significant or persistent diarrhea during or after antibiotic therapy may indicate C.
difficile infection. The patient requires appropriate clinical assessment rather than simply
treating the symptom as routine diarrhea.
, 11. Which statement best describes a partial agonist?
A. It binds only to inactive receptors
B. It has no affinity for the receptor
C. It produces a submaximal response even when occupying receptors fully
D. It irreversibly destroys the receptor
Answer: C
Rationale: A partial agonist activates a receptor but has lower intrinsic efficacy than a full
agonist. In the presence of a full agonist, it may also reduce the overall response by
competing for receptor occupancy.
12. A patient with renal impairment receives a medication that is predominantly eliminated
unchanged by the kidneys. What pharmacokinetic change is most likely?
A. Increased clearance
B. Decreased half-life
C. Increased first-pass metabolism
D. Reduced clearance and potentially increased drug exposure
Answer: D
Rationale: Reduced renal function can decrease clearance of renally eliminated drugs, causing
accumulation and increased exposure. Dose adjustment or increased monitoring may
therefore be required.
13. Which counseling point is most appropriate for a patient starting a bisphosphonate
such as alendronate?
A. Take it immediately before lying down
B. Take it with milk to improve absorption
C. Take it with plain water and remain upright afterward as directed
D. Crush it and take it with an antacid
Answer: C
Rationale: Oral bisphosphonates require specific administration to optimize absorption and
reduce esophageal irritation. They are generally taken with plain water while the patient
remains upright for the recommended period.
14. A patient taking lithium develops coarse tremor, vomiting, diarrhea, and confusion.
What should the pharmacist suspect?
A. Lithium toxicity
B. Therapeutic response
C. Mild seasonal allergy
D. Iron deficiency
Answer: A
