,Q1. A patient on a stable warfarin regimen is prescribed metronidazole for a dental
infection. Which change in the international normalized ratio (INR) is most likely,
and what is the primary mechanism?
A. Increased INR due to inhibition of CYP2C9, reducing warfarin metabolism
B. Decreased INR due to induction of CYP2C9, increasing warfarin metabolism
C. Increased INR due to displacement of warfarin from plasma proteins
D. Decreased INR due to increased vitamin K absorption from gut flora alteration
Correct Answer: A. Increased INR due to inhibition of CYP2C9, reducing warfarin
metabolism
Rationale: Metronidazole inhibits CYP2C9, the primary enzyme metabolizing S-warfarin,
leading to increased warfarin levels and INR. This can cause bleeding. Protein
displacement is a transient effect, not the primary mechanism. Induction would decrease
INR, and altered vitamin K absorption is not significant.
Why Wrong:
B - Metronidazole is an inhibitor, not an inducer, of CYP2C9.
C - Protein displacement is not the primary mechanism for this interaction.
D - Metronidazole does not significantly increase vitamin K absorption.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 4, 72.
Q2. Which pharmacodynamic principle best explains why a drug with a low
therapeutic index requires more rigorous monitoring compared to one with a high
therapeutic index?
A. The margin between the minimum effective concentration and the minimum toxic
concentration is narrow.
B. The drug has a short half-life, requiring more frequent dosing.
C. The drug exhibits zero-order kinetics at therapeutic doses.
D. The drug is highly protein-bound, limiting free drug concentration.
Correct Answer: A. The margin between the minimum effective concentration and
the minimum toxic concentration is narrow.
Rationale: Therapeutic index is the ratio of the toxic dose to the effective dose; a low index
means a narrow window between efficacy and toxicity, necessitating close monitoring.
Half-life, kinetics, and protein binding do not define therapeutic index.
Why Wrong:
B - Half-life affects dosing frequency, not the therapeutic index.
C - Zero-order kinetics can be a property of some drugs but does not define
therapeutic index.
D - Protein binding influences distribution but not the definition of therapeutic index.

, Q3. A patient with chronic kidney disease (estimated GFR 25 mL/min) requires an
antibiotic. Which agent is most likely to require dose adjustment, and which is safest?
A. Ceftriaxone requires adjustment; azithromycin is safest.
B. Levofloxacin requires adjustment; doxycycline is safest.
C. Amoxicillin requires adjustment; ceftriaxone is safest.
D. Ciprofloxacin requires adjustment; clindamycin is safest.
Correct Answer: B. Levofloxacin requires adjustment; doxycycline is safest.
Rationale: Levofloxacin is renally eliminated and needs dose reduction in CKD.
Doxycycline is hepatically eliminated and safe in renal impairment. Ceftriaxone is
partially biliary excreted but generally safe; amoxicillin requires adjustment;
ciprofloxacin requires adjustment; clindamycin is safe but not the best answer because
doxycycline is also safe and more commonly used.
Why Wrong:
A - Ceftriaxone is generally safe in renal impairment, and azithromycin is safe but not
the best pairing.
C - Amoxicillin requires adjustment, but ceftriaxone is not the safest option.
D - Ciprofloxacin requires adjustment, but clindamycin is not the safest option
compared to doxycycline.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 10, 67.
Q4. Which of the following is the most appropriate first-line therapy for a patient
with heart failure with reduced ejection fraction (HFrEF) and recent diagnosis of type
2 diabetes?
A. Metformin
B. SGLT2 inhibitor (e.g., empagliflozin)
C. Sulfonylurea (e.g., glipizide)
D. DPP-4 inhibitor (e.g., sitagliptin)
Correct Answer: B. SGLT2 inhibitor (e.g., empagliflozin)
Rationale: SGLT2 inhibitors are recommended in HFrEF regardless of diabetes status
due to cardiovascular benefits. Metformin is safe but not specifically indicated for HFrEF.
Sulfonylureas have neutral cardiovascular effects but can cause weight gain and
hypoglycemia. DPP-4 inhibitors have neutral effects but are not preferred in HFrEF.
Why Wrong:
A - Metformin is not the first-line for HFrEF specifically.
C - Sulfonylureas are not preferred due to weight gain and hypoglycemia risk.
D - DPP-4 inhibitors are not preferred over SGLT2 inhibitors in HFrEF.
