Q1. Which statement best describes pharmacokinetics?
A) The interaction of a drug with its receptor
B) The relationship between dose and clinical response only
C) The processes of absorption, distribution, metabolism, and excretion
D) The mechanism by which a drug produces toxicity
Correct Answer: C) The processes of absorption, distribution, metabolism,
and excretion
Rationale: Pharmacokinetics describes what the body does to a drug
through absorption, distribution, metabolism, and elimination.
Q2. Which statement best describes pharmacodynamics?
A) Movement of a medication through the gastrointestinal tract
B) Renal elimination of a medication
C) Hepatic metabolism of a medication
D) The biochemical and physiologic effects of a drug and its mechanism of
action
Correct Answer: D) The biochemical and physiologic effects of a drug and its
mechanism of action
Rationale: Pharmacodynamics describes what a medication does to the
body, including receptor interactions and resulting effects.
Q3. Which pharmacokinetic process occurs when a medication
moves from its administration site into systemic circulation?
A) Distribution
B) Absorption
C) Metabolism
D) Excretion
Correct Answer: B) Absorption
Rationale: Absorption is the movement of a drug from its site of
administration into the bloodstream.
Q4. Which route of administration provides 100% bioavailability?
A) Oral
B) Intravenous
C) Subcutaneous
D) Intramuscular
Correct Answer: B) Intravenous
Rationale: Intravenous administration places the entire dose directly into
systemic circulation.
, Q5. First-pass metabolism most significantly affects medications
administered by which route?
A) Oral
B) Intravenous
C) Transdermal
D) Sublingual
Correct Answer: A) Oral
Rationale: Many orally administered medications pass through the liver
before reaching systemic circulation and may undergo substantial
metabolism.
Q6. Which term describes the fraction of an administered dose that
reaches systemic circulation unchanged?
A) Clearance
B) Half-life
C) Bioavailability
D) Potency
Correct Answer: C) Bioavailability
Rationale: Bioavailability reflects how much of an administered medication
becomes available in systemic circulation.
Q7. A highly protein-bound medication is administered to a patient
with severe hypoalbuminemia. What is the most likely result?
A) Decreased free drug concentration
B) Increased free drug concentration and potential toxicity
C) Complete loss of drug absorption
D) Increased albumin production
Correct Answer: B) Increased free drug concentration and potential toxicity
Rationale: Reduced albumin leaves a greater proportion of highly protein-
bound medication unbound and pharmacologically active.
Q8. Which factor most directly influences a drug's volume of
distribution?
A) Distribution into body tissues and fluids
B) Only renal filtration
C) Only hepatic enzyme activity
D) Only gastrointestinal motility
Correct Answer: A) Distribution into body tissues and fluids
Rationale: Volume of distribution reflects the extent to which a medication
leaves plasma and distributes into tissues.
