Section 1: Pharmacokinetics & Pharmacodynamics
1. A drug with a high first-pass effect is best administered by which route to maximize
bioavailability? A. Oral B. Sublingual C. Rectal (upper) D. Intramuscular
Correct Answer: B Rationale: Sublingual administration allows the drug to be absorbed
directly into systemic circulation via the oral mucosa, bypassing the hepatic portal system
entirely. Oral drugs with high first-pass metabolism lose significant potency before reaching
, systemic circulation because the liver metabolizes a large fraction before it ever reaches target
tissues.
2. A patient with liver cirrhosis is prescribed a drug that is highly protein-bound and
hepatically metabolized. What is the primary concern? A. Decreased half-life and
subtherapeutic dosing B. Increased free drug concentration and risk of toxicity C. Increased renal
clearance of the drug D. No significant change in pharmacokinetics
Correct Answer: B Rationale: Cirrhosis reduces hepatic synthesis of albumin, decreasing
protein-binding capacity. With less albumin available, more of the drug remains "free" (unbound)
and pharmacologically active, increasing the risk of toxicity even at standard doses. Hepatic
impairment also slows metabolism, prolonging drug half-life.
3. Zero-order kinetics differs from first-order kinetics in that: A. A constant percentage of
drug is eliminated per unit time B. A constant amount of drug is eliminated per unit time,
regardless of concentration C. Elimination rate is proportional to drug concentration D. Zero-
order kinetics only applies to renally excreted drugs
Correct Answer: B Rationale: In zero-order kinetics, elimination occurs at a fixed rate (a
constant amount per unit time) because the elimination pathway is saturated. This differs from
first-order kinetics, where a constant fraction/percentage is eliminated per unit time, proportional
to the drug's concentration. Phenytoin and alcohol are classic zero-order examples.
4. Which factor most directly determines a drug's loading dose calculation? A. Half-life B.
Volume of distribution C. Clearance D. Bioavailability alone
Correct Answer: B Rationale: Loading dose = (Target concentration × Volume of distribution) /
Bioavailability. Volume of distribution reflects how extensively a drug disperses into body
tissues versus remaining in plasma, and it directly determines how much total drug is needed to
rapidly achieve a target plasma concentration.
5. A patient taking warfarin is started on a CYP2C9 inhibitor. What is the expected clinical
effect? A. Decreased INR and reduced anticoagulation B. Increased INR and increased bleeding
risk C. No effect, since warfarin is renally cleared D. Immediate reversal of anticoagulation
Correct Answer: B Rationale: Warfarin is metabolized primarily by CYP2C9. A CYP2C9
inhibitor slows warfarin metabolism, increasing plasma warfarin levels, which raises the INR
