Week 1 Quiz Questions
Pharmacokinetics and Pharmacodynamics
1. What does pharmacokinetics primarily refer to?
o A) Biochemical effects of drugs on the body
o B) Study of drug absorption, distribution, metabolism, and excretion
o C) Drug-receptor interactions
o D) Adverse drug reactions
o Answer: Study of drug absorption, distribution, metabolism, and excretion
o Rationale: Pharmacokinetics studies how the body processes a drug, including
absorption, distribution, metabolism, and excretion ("what the body does to the
drug").
2. Which factors affect drug absorption? (Select all that apply)
o A) Rate of dissolution
o B) Surface area
o C) Blood flow
o D) Protein-binding capacity
o Answer: Rate of dissolution, Surface area, Blood flow
o Rationale: Drug absorption is influenced by dissolution rate, surface area of the
absorption site, and blood flow. Protein-binding capacity affects distribution, not
absorption.
3. Pharmacodynamics is best described as:
o A) Movement of drugs through the body
o B) Biochemical and physiologic effects of drugs on the body
o C) Drug excretion rates
o D) Drug solubility in blood
o Answer: Biochemical and physiologic effects of drugs on the body
o Rationale: Pharmacodynamics studies how drugs affect the body and their
mechanisms of action ("what the drug does to the body").
4. What are the three primary mechanisms of action in pharmacodynamics?
o A) Receptor, enzyme, non-selective interactions
o B) Absorption, distribution, metabolism
o C) Agonist, antagonist, partial agonist
o D) Oxidation, reduction, hydrolysis
o Answer: Receptor, enzyme, non-selective interactions
, o Rationale: Pharmacodynamic mechanisms include receptor interactions, enzyme
modulation, and non-selective interactions (e.g., chemotherapy).
5. Which factor affects drug distribution?
o A) Blood-brain barrier
o B) Rate of dissolution
o C) pH partitioning
o D) Lipid solubility
o Answer: Blood-brain barrier
o Rationale: The blood-brain barrier restricts drug distribution to the central
nervous system, a key factor in distribution. Others affect absorption.
Drug Interactions and Adverse Effects
6. What is a black-box warning?
o A) A warning for minor side effects
o B) A notification of serious or life-threatening risks
o C) A contraindication for all patients
o D) A recall notice for a drug
o Answer: A notification of serious or life-threatening risks
o Rationale: Black-box warnings indicate serious or life-threatening risks but do
not prohibit prescription.
7. A drug interaction where two drugs compete for metabolizing enzymes is classified
as:
o A) Additive
o B) Synergistic
o C) Drug-drug
o D) Antagonistic
o Answer: Drug-drug
o Rationale: Drug-drug interactions occur when two drugs compete for the same
metabolizing enzymes, altering their effects.
8. Which food is most likely to cause a food-drug interaction?
o A) Dairy products
o B) Grapefruit juice
o C) Bread
o D) Lean protein
o Answer: Grapefruit juice
o Rationale: Grapefruit juice inhibits CYP450 enzymes, affecting drug metabolism
and increasing drug levels.
9. An idiosyncratic effect is best described as:
o A) An expected side effect
o B) An unexpected response to a medication
o C) A dose-dependent reaction
o D) An allergic reaction
o Answer: An unexpected response to a medication
o Rationale: Idiosyncratic effects are unpredictable and unique to the individual.
10. What is a synergistic drug interaction?
