PRC PHARMACIST LICENSURE EXAMINATION | ALL
QUESTIONS AND ANSWERS | A+ GRADED |
COMPREHENSIVE EXAM GUIDE 2026/2027
1. A patient with hypertension is newly prescribed lisinopril. During counseling, which
adverse effect should the pharmacist emphasize as requiring prompt medical attention?
A. Mild transient headache
B. Increased appetite
C. Persistent dry cough
D. Orange discoloration of urine
Answer: C
Rationale: Persistent dry cough is a recognized adverse effect of ACE inhibitors such as
lisinopril and may require therapy reassessment.
2. Which pharmacokinetic process describes the movement of a drug from its site of
administration into systemic circulation?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Answer: A
Rationale: Absorption is the movement of a drug from the administration site into the systemic
circulation.
3. A pharmacist receives a prescription for a drug with a narrow therapeutic index. Which
action is most appropriate before dispensing?
A. Substitute an OTC product
B. Ignore the dose because the drug is routinely used
C. Automatically double the prescribed dose
D. Carefully verify the dose, patient factors, and potential interactions
Answer: D
Rationale: Narrow-therapeutic-index drugs require careful dose verification because relatively
small concentration changes may cause toxicity or treatment failure.
4. Which dosage form is generally designed to release medication slowly over an extended
period?
A. Immediate-release tablet
, B. Extended-release tablet
C. Oral solution
D. Sublingual tablet
Answer: B
Rationale: Extended-release formulations are designed to release active drug over an extended
period, helping maintain therapeutic concentrations.
5. A patient taking warfarin begins using an OTC NSAID for back pain without consulting
the pharmacist. What is the primary concern?
A. Severe hypoglycemia
B. Reduced anticoagulant activity
C. Increased risk of bleeding
D. Permanent renal failure in every patient
Answer: C
Rationale: NSAIDs can increase bleeding risk through gastrointestinal effects and platelet
inhibition when combined with anticoagulant therapy.
6. Which organ is the primary site of most hepatic phase I drug metabolism?
A. Liver
B. Spleen
C. Pancreas
D. Thyroid
Answer: A
Rationale: The liver contains extensive drug-metabolizing enzyme systems, particularly the
cytochrome P450 system involved in many phase I reactions.
7. A prescription contains an unclear abbreviation that could result in a tenfold dosing
error. What should the pharmacist do?
A. Guess the intended meaning from previous prescriptions
B. Clarify the prescription with the prescriber before dispensing
C. Ask the patient to choose the intended dose
D. Dispense the lowest possible dose
Answer: B
Rationale: Ambiguous directions that could cause significant medication harm must be
clarified before dispensing.
8. Which route of administration generally provides the fastest systemic effect when the
drug is administered appropriately?
, A. Oral
B. Rectal
C. Intramuscular
D. Intravenous
Answer: D
Rationale: Intravenous administration places the drug directly into systemic circulation,
producing rapid systemic availability.
9. A patient reports swelling of the lips and difficulty breathing shortly after taking a
medication. What is the pharmacist's priority?
A. Recommend taking the next dose with food
B. Treat the reaction as a minor side effect
C. Recognize a potentially life-threatening hypersensitivity reaction and arrange emergency
care
D. Recommend an antacid
Answer: C
Rationale: Lip swelling and difficulty breathing can indicate anaphylaxis or severe
angioedema and require immediate emergency management.
10. Which statement best describes bioavailability?
A. The fraction of administered drug that reaches systemic circulation unchanged
B. The amount of drug eliminated in urine
C. The amount of drug bound to plasma proteins
D. The duration of drug action
Answer: A
Rationale: Bioavailability refers to the fraction of an administered dose that reaches systemic
circulation in unchanged form.
11. A patient with type 2 diabetes is prescribed metformin. Which counseling point is most
appropriate?
A. Stop all carbohydrate intake
B. Take the medication only when glucose is high
C. Expect severe hypoglycemia with every dose
D. Gastrointestinal effects may occur, particularly when therapy is initiated
Answer: D
Rationale: Gastrointestinal adverse effects such as nausea and diarrhea are common with
metformin, especially early in treatment.
, 12. Which antibiotic class inhibits bacterial cell-wall synthesis?
A. Macrolides
B. Beta-lactams
C. Tetracyclines
D. Fluoroquinolones
Answer: B
Rationale: Beta-lactam antibiotics inhibit bacterial cell-wall synthesis by interfering with
peptidoglycan cross-linking.
13. A patient taking tetracycline asks whether it can be taken simultaneously with an
aluminum-containing antacid. What is the best advice?
A. Separate administration because the antacid can reduce absorption
B. Take both together to improve absorption
C. Double the tetracycline dose
D. Crush both products together
Answer: A
Rationale: Divalent and trivalent cations can chelate tetracyclines and significantly reduce
their absorption.
14. Which laboratory value is most directly useful for assessing long-term glycemic
control?
A. Serum sodium
B. Serum creatinine
C. Hemoglobin A1c
D. Serum potassium
Answer: C
Rationale: Hemoglobin A1c reflects average blood glucose exposure over approximately the
preceding two to three months.
15. A patient taking digoxin reports nausea, visual disturbances, and palpitations. What
should the pharmacist suspect?
A. Expected therapeutic effects
B. Iron deficiency
C. Vitamin deficiency
D. Possible digoxin toxicity
Answer: D
Rationale: Gastrointestinal symptoms, visual changes, and cardiac rhythm disturbances are
classic warning signs of possible digoxin toxicity.
