,An introduction to pharmacology
,Chapter 1 — Introduction to Pharmacology
1. Which statement best describes pharmacology?
Multiple Choice
A. The study of surgical procedures
B. The study of drugs and their effects on living organisms
C. The study of infectious microorganisms only
D. The study of human anatomy
Correct Answer: B
Rationale: Pharmacology is the science concerned with drugs, including their sources,
properties, mechanisms of action, therapeutic uses, and effects on living organisms. It
encompasses both how drugs affect the body and how the body handles drugs.
2. What term describes the study of how a drug produces its effects on the body?
Multiple Choice
A. Pharmacokinetics
B. Pharmacodynamics
C. Pharmacognosy
D. Toxicology
Correct Answer: B
Rationale: Pharmacodynamics examines the biochemical and physiological effects of drugs
and their mechanisms of action. Pharmacokinetics, in contrast, focuses on what the body
does to a drug, including absorption, distribution, metabolism, and excretion.
3. Which process describes the movement of a drug from its site of administration into the
bloodstream?
Multiple Choice
A. Absorption
B. Distribution
, C. Metabolism
D. Excretion
Correct Answer: A
Rationale: Absorption is the movement of a drug from its administration site into systemic
circulation. The route of administration, drug formulation, blood flow, and other factors can
influence the rate and extent of absorption.
4. Which organ is primarily responsible for drug metabolism?
Multiple Choice
A. Heart
B. Liver
C. Spleen
D. Pancreas
Correct Answer: B
Rationale: The liver is the major site of drug metabolism. Hepatic enzymes chemically modify
many drugs, often converting them into metabolites that can be more readily eliminated from
the body.
5. Which term refers to the removal of drugs and their metabolites from the body?
Multiple Choice
A. Absorption
B. Distribution
C. Excretion
D. Receptor binding
Correct Answer: C
Rationale: Excretion is the process by which drugs or their metabolites leave the body. The
kidneys are particularly important because many substances are eliminated through urine.
6. A drug that binds to a receptor and produces a biological response is called a(n):
