PHARMACOKINETICS & PHARMACODYNAMICS (Questions 1-30)
Question 1
What does pharmacokinetics involve?
A) The study of drug-receptor interactions and mechanisms of
action
B) The process of ADME (absorption, distribution, metabolism, and
elimination)
C) The study of drug toxicity and adverse effects
D) The process of drug manufacturing and formulation
Correct ,,,answer,,,,: B) The process of ADME (absorption,
distribution, metabolism, and elimination)
,Rationale: Pharmacokinetics is what the body does to the drug,
involving Absorption (administration site to blood/plasma),
Distribution (bloodstream to interstitial/intracellular fluid),
Metabolism (biotransformation via hepatic metabolism or other
tissues), and Elimination (drug and metabolites removed from the
body) .
Question 2
Which route of administration has the highest bioavailability?
A) Oral
B) Intramuscular
C) Intravenous
D) Sublingual
Correct ,,,answer,,,,: C) Intravenous
Rationale: The intravenous route places the entire dose directly into
a patient's vein, bypassing absorption entirely. It also avoids first-
pass metabolism in the liver, which can destroy a significant portion
of orally administered drugs before they reach systemic circulation .
Question 3
What is a disadvantage of rectal administration?
A) Complete absorption with no variability
B) Variable and erratic absorption
C) Always requires first-pass metabolism
D) Cannot be used for systemic medications
Correct ,,,answer,,,,: B) Variable and erratic absorption
,Rationale: Rectal administration can have variable and
unpredictable absorption due to factors such as the presence of
stool, rectal pH, and blood flow. This variability makes it less reliable
than other routes for achieving consistent drug levels .
Question 4
When is steady state (SS) of a drug usually reached?
A) Immediately after the first dose
B) Within 1-2 half-lives of the drug
C) Within 4-5 half-lives of the drug
D) After 7-10 half-lives of the drug
Correct ,,,answer,,,,: C) Within 4-5 half-lives of the drug
Rationale: Steady state is usually reached within 4-5 half-lives of a
drug. At this point, drug administration and elimination are
balanced, resulting in relatively constant plasma drug levels with
each dose .
Question 5
How is the half-life of a drug defined?
A) The time required for the drug to reach peak concentration
B) How long it takes for half the drug to be excreted from the body
C) The time required for the drug to be completely eliminated
D) The duration of therapeutic effect of the drug
Correct ,,,answer,,,,: B) How long it takes for half the drug to be
excreted from the body
Rationale: The half-life of a drug is defined as how long it takes for
half the drug to be excreted from the body. It determines how
, frequently the drug must be administered and predicts how long
toxic effects can last .
Question 6
Which statement about half-life is true with first-order
pharmacokinetics?
A) Half-life increases as drug concentration increases
B) Half-life is constant
C) Half-life is variable based on patient age only
D) Half-life cannot be calculated
Correct ,,,answer,,,,: B) Half-life is constant
Rationale: With first-order pharmacokinetics, the half-life is
constant, meaning the fraction of drug eliminated per unit time is
constant regardless of drug concentration. Zero-order (nonlinear)
pharmacokinetics means a drug is metabolized at a constant rate
per unit time .
Question 7
What is a prodrug?
A) An active drug that requires no metabolism
B) An inactive drug dosage form converted to an active metabolite
inside the body
C) A drug that is always administered intravenously
D) A drug that cannot be absorbed orally
Correct ,,,answer,,,,: B) An inactive drug dosage form converted to an
active metabolite inside the body
