# SECTION 1: PHARMACOKINETICS & PHARMACODYNAMICS
– Questions 1–20
**1. A drug with a half-life of 8 hours is administered intravenously.
Approximately how long will it take to reach steady state?**
A) 16 hours
B) 24 hours
C) 40 hours (5 × half-life = 40 hours)
D) 8 hours
**Answer: C**
*Rationale:* Steady state is reached after approximately 4-5 half-lives. 5
× 8 hours = 40 hours. Steady state occurs when rate of drug
administration equals rate of elimination.
**2. A drug has a volume of distribution (Vd) of 50 L. This indicates
that the drug is:**
A) Primarily confined to the vascular compartment (low Vd)
B) Widely distributed into tissues (high Vd suggests extensive tissue
binding)
C) Highly protein-bound
D) Eliminated rapidly
,3|Page
**Answer: B**
*Rationale:* Volume of distribution reflects the extent of drug
distribution into tissues. High Vd (>42 L) indicates extensive tissue
binding or accumulation (e.g., digoxin, amiodarone). Low Vd indicates
confinement to blood (e.g., warfarin, which is highly protein-bound).
**3. Which of the following is an example of pharmacodynamic drug
interaction?**
A) Warfarin and rifampin (rifampin induces CYP2C9, decreasing
warfarin effect – pharmacokinetic)
B) Propranolol and albuterol (antagonistic effect at beta receptors)
C) Digoxin and amiodarone (amiodarone increases digoxin levels –
pharmacokinetic)
D) Grapefruit juice and simvastatin (inhibits CYP3A4 –
pharmacokinetic)
**Answer: B**
*Rationale:* Pharmacodynamic interactions occur when drugs interact
at receptor sites. Propranolol (beta-blocker) antagonizes albuterol (beta-
agonist) at beta-2 receptors in the lungs. The others are pharmacokinetic
(absorption, distribution, metabolism, excretion).
**4. A patient with hepatic cirrhosis has decreased albumin levels. How
will this affect a highly protein-bound drug such as phenytoin?**
A) Decreased free drug concentration (increased free fraction)
, 4|Page
B) Increased free drug concentration (increased risk of toxicity)
C) No change
D) Decreased volume of distribution
**Answer: B**
*Rationale:* Hypoalbuminemia reduces protein binding sites, increasing
the free (unbound) fraction of highly protein-bound drugs. Free drug is
pharmacologically active, increasing risk of toxicity. Monitor free drug
levels.
**5. A 70-year-old patient is prescribed a medication that is primarily
renally excreted. Which pharmacokinetic change in the elderly is most
relevant?**
A) Decreased hepatic metabolism (phase I)
B) Decreased glomerular filtration rate (GFR)
C) Increased volume of distribution for lipophilic drugs
D) Increased gastric pH
**Answer: B**
*Rationale:* Renal function (GFR) declines with age (~1 mL/min/year
after age 40). Drugs primarily excreted unchanged by the kidney require
dose adjustment to prevent accumulation and toxicity.
**6. Zero-order kinetics (nonlinear kinetics) is best described as:**
