,Q1. A drug displays Michaelis-Menten kinetics with a Vmax of 40 mg/h and Km of 5
mg/L. If the patient's hepatic blood flow is reduced by 50% due to heart failure, what
is the most likely effect on the drug's steady-state concentration when administered at
a dose of 60 mg/day?
A. Decrease due to increased free fraction
B. Increase disproportionately to the reduction in clearance
C. No change because capacity-limited clearance is independent of blood flow
D. Decrease because of reduced first-pass metabolism
Correct Answer: B. Increase disproportionately to the reduction in clearance
Rationale: Drugs with capacity-limited (saturable) clearance have a clearance that
depends on intrinsic enzyme activity, not blood flow. However, when the dose approaches
Vmax, a small reduction in clearance causes a large increase in steady-state
concentration, since Cp = (rate of administration) / clearance. Reduced hepatic blood flow
does not directly affect intrinsic clearance, but in this case, the drug's concentration is
already near saturation, so the reduction in clearance (from any cause) leads to a
disproportionate rise. Options A and D are incorrect because blood flow reduction does
not increase free fraction or reduce first-pass metabolism for a low-extraction drug.
Why Wrong:
A - Free fraction is determined by protein binding, not hepatic blood flow.
C - While capacity-limited clearance is independent of blood flow, the concentration
does change if clearance is altered by other factors; here, the question states blood
flow reduction, but the effect is still on total clearance.
D - First-pass metabolism is not the primary determinant for a low-extraction drug.

Q2. A patient on warfarin is prescribed metronidazole for a dental infection. Which
of the following best describes the pharmacodynamic/pharmacokinetic interaction
that necessitates a dose adjustment?
A. Metronidazole displaces warfarin from albumin, increasing free warfarin
concentration.
B. Metronidazole inhibits CYP2C9, reducing warfarin metabolism and increasing INR.
C. Metronidazole induces CYP3A4, increasing warfarin clearance and reducing INR.
D. Metronidazole antagonizes vitamin K epoxide reductase, directly enhancing
warfarin's effect.
Correct Answer: B. Metronidazole inhibits CYP2C9, reducing warfarin metabolism
and increasing INR.
Rationale: Metronidazole is a potent inhibitor of CYP2C9, the primary enzyme
responsible for metabolizing the S-enantiomer of warfarin. This inhibition decreases
warfarin clearance, leading to elevated INR and increased bleeding risk. Warfarin is
Page 3
, highly protein-bound, but displacement interactions are clinically negligible because the
increased free fraction is rapidly metabolized. Metronidazole does not induce CYP3A4 or
directly affect vitamin K epoxide reductase.
Why Wrong:
A - Plasma protein displacement is transient and not the primary mechanism for this
clinically significant interaction.
C - Metronidazole is an inhibitor, not an inducer, of CYP enzymes.
D - Warfarin itself inhibits VKOR; metronidazole does not have this direct effect.

Anticoagulant Drugs.
Q3. A patient with type 2 diabetes and chronic kidney disease (eGFR 25
mL/min/1.73m²) is currently on metformin. According to current guidelines, which of
the following is the most appropriate recommendation?
A. Continue metformin at the same dose; it is safe at any eGFR.
B. Discontinue metformin immediately due to contraindication at eGFR < 30.
C. Reduce metformin dose by 50% and monitor renal function monthly.
D. Switch to metformin extended-release to reduce renal excretion.
Correct Answer: B. Discontinue metformin immediately due to contraindication at
eGFR < 30.
Rationale: Current FDA guidelines state that metformin is contraindicated when eGFR
falls below 30 mL/min/1.73m² due to the risk of lactic acidosis. At eGFR 25, the drug
should be discontinued. While some guidelines allow reduced doses down to eGFR 30,
below that threshold the risk outweighs benefit. Extended-release formulations do not alter
renal clearance.
Why Wrong:
A - Metformin is not safe at any eGFR; it is contraindicated below 30.
C - Dose reduction is recommended for eGFR 30-45, not below 30.
D - Extended-release metformin has the same renal clearance and contraindication.

Q4. A patient is prescribed a drug that is a weak acid with a pKa of 4.4. If the urine
pH is 8.0, which of the following statements best describes the drug's renal excretion?
A. The drug will be mostly ionized and reabsorbed, reducing excretion.
B. The drug will be mostly non-ionized and reabsorbed, reducing excretion.
C. The drug will be mostly ionized and trapped in the urine, increasing excretion.
D. The drug will be mostly non-ionized and excreted rapidly in the urine.
Correct Answer: C. The drug will be mostly ionized and trapped in the urine,
increasing excretion.
