,Q1. A drug with a volume of distribution (Vd) of 500 L is administered at a dose of
250 mg IV. Which of the following best describes the initial plasma concentration
(C0)?
A. 0.5 mg/L
B. 0.05 mg/L
C. 5 mg/L
D. 50 mg/L
Correct Answer: A. 0.5 mg/L
Rationale: C0 = dose / Vd = 250 mg / 500 L = 0.5 mg/L. The other options result from
arithmetic errors (e.g., misplacing decimal, inverting ratio).
Why Wrong:
B - This would result from dividing 250 by 5000, not 500.
C - This would result from dividing 2500 by 500, not 250 by 500.
D - This would result from dividing 250 by 5, not 500.

Q2. Which of the following receptor types typically mediates the effects of insulin and
growth factors, leading to tyrosine kinase activation?
A. G-protein coupled receptors
B. Ligand-gated ion channels
C. Enzyme-linked receptors
D. Intracellular nuclear receptors
Correct Answer: C. Enzyme-linked receptors
Rationale: Insulin and growth factor receptors are enzyme-linked receptors with intrinsic
tyrosine kinase activity. GPCRs use second messengers, ion channels mediate fast synaptic
transmission, and nuclear receptors act as transcription factors.
Why Wrong:
A - GPCRs mediate signals through G-proteins and second messengers, not direct
kinase activity.
B - Ligand-gated ion channels directly control ion flux, not enzyme activation.
D - Intracellular receptors respond to lipid-soluble ligands and modulate gene
transcription.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 3
Q3. A patient with a CYP2C19 poor metabolizer phenotype is prescribed clopidogrel.
Which of the following is the most appropriate pharmacogenomic-guided
adjustment?
A. Increase the clopidogrel dose to achieve therapeutic antiplatelet effect
Page 3
, B. Switch to prasugrel or ticagrelor
C. Add a proton pump inhibitor to reduce bleeding risk
D. No adjustment is needed; clopidogrel is unaffected by CYP2C19
Correct Answer: B. Switch to prasugrel or ticagrelor
Rationale: CYP2C19 poor metabolizers fail to convert clopidogrel to its active metabolite,
reducing antiplatelet efficacy. Guidelines recommend alternative P2Y12 inhibitors like
prasugrel or ticagrelor. Increasing dose is not recommended; PPIs may further inhibit
CYP2C19.
Why Wrong:
A - Dose escalation is not supported by evidence and may not overcome the metabolic
block.
C - PPIs that inhibit CYP2C19 can worsen the problem, not improve it.
D - CYP2C19 status significantly affects clopidogrel activation.
Reference: CPIC Guideline (2022) for clopidogrel and CYP2C19
Q4. Which of the following best explains the development of tolerance to opioids after
chronic use?
A. Upregulation of mu-opioid receptors
B. Desensitization and downregulation of mu-opioid receptors
C. Increased metabolism of opioids by the liver
D. Enhanced blood-brain barrier efflux of opioids
Correct Answer: B. Desensitization and downregulation of mu-opioid receptors
Rationale: Chronic opioid exposure leads to receptor desensitization (uncoupling from
G-proteins) and downregulation, reducing response. Upregulation would increase
sensitivity, and metabolic or efflux changes are not primary mechanisms.
Why Wrong:
A - Upregulation would enhance opioid effects, not reduce them.
C - Metabolic tolerance can occur but is not the primary mechanism for opioids.
D - Efflux transporter changes are not a major contributor to opioid tolerance.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 24
Q5. A patient on warfarin is prescribed a course of rifampin. Which of the following
effects is most likely on INR and how should the warfarin dose be adjusted?
A. INR increases; warfarin dose should be reduced
B. INR decreases; warfarin dose should be increased
C. INR remains stable; no dose adjustment needed
D. INR increases; warfarin dose should be increased
Correct Answer: B. INR decreases; warfarin dose should be increased
