SECTION 1: PHARMACOKINETICS & PHARMACODYNAMICS (Questions 1-25)
1. Which of the following best describes bioavailability?
A) The rate at which a drug is absorbed from the gastrointestinal tract
B) The fraction of administered drug that reaches systemic circulation in unchanged
form
C) The volume of distribution of a drug in the body
D) The half-life of a drug in plasma
E) The rate of hepatic metabolism of a drug
,CORRECT ANSWER: B. The fraction of administered drug that reaches systemic
circulation in unchanged form
Bioavailability (F) is defined as the fraction of an administered dose that reaches the
systemic circulation in unchanged (active) form. It accounts for incomplete
absorption and first-pass metabolism. Oral bioavailability is typically less than 100%
due to incomplete absorption and hepatic first-pass metabolism. Intravenous
administration has 100% bioavailability by definition. Option A describes absorption
rate, not bioavailability. Option C describes Vd. Option D describes half-life. Option
E describes one factor that affects bioavailability but is not the definition itself.
2. A patient receives a drug intravenously and plasma concentrations are
measured over time. The half-life of the drug is determined to be 6 hours.
How long will it take for the drug concentration to reach 12.5% of the original
dose?
A) 6 hours
B) 12 hours
C) 18 hours
D) 24 hours
E) 36 hours
CORRECT ANSWER: C. 18 hours
Half-life is the time it takes for plasma concentration to decrease by 50%. After one
half-life (6 hours), 50% remains. After two half-lives (12 hours), 25% remains. After
three half-lives (18 hours), 12.5% remains. This is calculated as: Remaining % = 100
× (0.5)^n, where n is the number of half-lives. Three half-lives = 3 × 6 = 18 hours.
3. Which phase of pharmacokinetics represents the movement of drugs from
the site of administration into the bloodstream?
A) Distribution
,B) Metabolism
C) Absorption
D) Elimination
E) Excretion
CORRECT ANSWER: C. Absorption
Absorption is the first phase of pharmacokinetics and involves the movement of
drug molecules from the site of administration (oral, IM, topical, etc.) across
biological membranes into the bloodstream. Distribution follows absorption and
involves movement from blood into tissues. Metabolism and elimination are later
phases. Excretion is part of elimination but occurs after distribution and
metabolism.
4. A drug has a volume of distribution (Vd) of 140 L in a 70 kg patient. What
does this indicate about the drug's distribution characteristics?
A) The drug is highly lipophilic and extensively distributed to tissues
B) The drug remains primarily in the vascular compartment
C) The drug cannot cross the blood-brain barrier
D) The drug has poor oral bioavailability
E) The drug undergoes rapid hepatic metabolism
CORRECT ANSWER: A. The drug is highly lipophilic and extensively distributed
to tissues
A Vd of 140 L in a 70 kg patient (2 L/kg) indicates extensive tissue distribution
beyond plasma volume (~3.5 L) and extracellular fluid volume (~14 L). This suggests
the drug is lipophilic (fat-soluble) and readily crosses biological membranes into
tissue compartments. A Vd approaching body weight indicates high lipophilicity and
tissue binding. A low Vd (remaining in plasma) would suggest hydrophilicity. Vd
does not predict BBB penetration, bioavailability, or metabolism rate.
, 5. Which of the following correctly describes the relationship between drug
clearance and half-life?
A) Clearance is independent of half-life
B) Half-life is proportional to clearance and inversely proportional to volume of
distribution
C) Clearance determines the rate of drug elimination only in first-order kinetics
D) Half-life increases when clearance increases
E) Clearance is measured in mg/kg and half-life in hours
CORRECT ANSWER: B. Half-life is proportional to clearance and inversely
proportional to volume of distribution
The relationship between half-life, clearance, and Vd is: t½ = 0.693 × Vd / CL. Half-
life is directly proportional to Vd (larger Vd = longer half-life) and inversely
proportional to clearance (higher clearance = shorter half-life). This relationship
holds for first-order kinetics. Understanding this relationship is essential for
predicting how changes in these parameters affect drug dosing.
6. A patient with severe renal impairment is prescribed a drug that is 90%
renally excreted unchanged. What pharmacokinetic parameter would be
most significantly affected?
A) Volume of distribution
B) Absorption rate
C) Clearance
D) Bioavailability
E) Protein binding
CORRECT ANSWER: C. Clearance
Clearance (CL) is most significantly affected by renal impairment when a drug is
predominantly renally excreted. Renal clearance accounts for approximately 90% of
