,Q1. A patient on warfarin is started on metronidazole for a dental infection. Which
pharmacodynamic principle best explains the resulting elevation in INR?
A. Inhibition of CYP2C9 leading to reduced warfarin clearance
B. Displacement of warfarin from protein binding sites
C. Additive inhibition of vitamin K-dependent clotting factors
D. Induction of CYP3A4 increasing warfarin metabolism
Correct Answer: A. Inhibition of CYP2C9 leading to reduced warfarin clearance
Rationale: Metronidazole inhibits CYP2C9, the primary enzyme that metabolizes the
S-enantiomer of warfarin, thereby increasing warfarin levels and INR. Protein binding
displacement is clinically insignificant for warfarin, and metronidazole does not directly
affect clotting factor synthesis or induce CYP enzymes.
Why Wrong:
B - Protein binding displacement is transient and not the primary mechanism for this
interaction.
C - Metronidazole does not have a direct pharmacodynamic effect on vitamin
K-dependent clotting factors.
D - Metronidazole inhibits, not induces, CYP enzymes.

Q2. In a patient with chronic kidney disease (CrCl 25 mL/min), which antibiotic
requires the most significant dose adjustment to avoid neurotoxicity?
A. Azithromycin
B. Ceftriaxone
C. Ciprofloxacin
D. Nitrofurantoin
Correct Answer: C. Ciprofloxacin
Rationale: Ciprofloxacin is renally eliminated and accumulates in renal impairment,
increasing the risk of CNS toxicity (seizures, confusion). Azithromycin is hepatically
cleared, ceftriaxone is partially biliary, and nitrofurantoin is contraindicated in renal
impairment, but it primarily causes pulmonary toxicity rather than neurotoxicity.
Why Wrong:
A - Azithromycin is primarily hepatically metabolized and does not require dose
adjustment in renal impairment.
B - Ceftriaxone is mainly eliminated via bile and does not require significant renal
dose adjustment.
D - Nitrofurantoin is contraindicated in renal impairment due to lack of efficacy and
pulmonary toxicity, not neurotoxicity.

, Q3. A patient with type 2 diabetes has an eGFR of 45 mL/min/1.73m² and persistent
hyperglycemia on metformin. Which agent is preferred as add-on therapy to
minimize cardiovascular risk?
A. Empagliflozin
B. Glipizide
C. Sitagliptin
D. Insulin glargine
Correct Answer: A. Empagliflozin
Rationale: Empagliflozin, an SGLT2 inhibitor, has proven cardiovascular benefit and is
renally safe down to eGFR 30, making it the preferred add-on in this setting. Glipizide has
no CV benefit, sitagliptin is neutral, and insulin is not preferred first-line add-on.
Why Wrong:
B - Sulfonylureas do not confer cardiovascular benefit and may increase
hypoglycemia risk.
C - DPP-4 inhibitors are cardiovascular neutral but not preferred over SGLT2
inhibitors for CV risk reduction.
D - Insulin is reserved for later stages or severe hyperglycemia, not as the preferred
add-on.

Q4. Which pharmacogenetic variant is associated with an increased risk of severe
skin reactions to carbamazepine in individuals of Asian descent?
A. HLA-B*15:02
B. CYP2D6 poor metabolizer
C. UGT1A1*28
D. CYP2C9*2
Correct Answer: A. HLA-B*15:02
Rationale: HLA-B*15:02 is strongly associated with Stevens-Johnson syndrome and toxic
epidermal necrolysis in Asian patients taking carbamazepine. CYP2D6, UGT1A1, and
CYP2C9 variants are not linked to this hypersensitivity.
Why Wrong:
B - CYP2D6 affects metabolism of many drugs but is not associated with
carbamazepine-induced skin reactions.
C - UGT1A1*28 is related to irinotecan toxicity, not carbamazepine hypersensitivity.
D - CYP2C9 variants affect warfarin and phenytoin metabolism, not carbamazepine
skin reactions.
