PRINCIPLES QUESTIONS WITH

SOLUTIONS: WALDEN UNIVERSITY
1. Which process describes what the body does to a drug, including absorption, distribution,
metabolism, and excretion?
A. Pharmacodynamics
B. Pharmacotherapeutics
C. Pharmacokinetics
D. Pharmacogenomics
Answer: C
Conceptual Explanation: Pharmacokinetics refers to the movement of drugs through the
body (what the body does to the drug), whereas pharmacodynamics is what the drug does
to the body.
2. A drug that binds to a receptor and produces a maximum biological response is known as a:
A. Partial agonist
B. Antagonist
,C. Full agonist
D. Inverse agonist
Answer: C
Conceptual Explanation: A full agonist binds to a receptor and mimics the endogenous
hormone or neurotransmitter to produce a full response.
3. The ‘First-Pass Effect’ primarily occurs with which route of administration?
A. Intravenous
B. Sublingual
C. Transdermal
D. Oral
Answer: D
Conceptual Explanation: Drugs taken orally are absorbed in the GI tract and carried to the
liver via the portal vein, where they may be metabolized before reaching systemic
circulation.
4. Which of the following describes the ‘Therapeutic Index’ of a drug?
A. The ratio between the toxic dose and the effective dose
B. The time it takes for a drug to reach steady state
C. The rate at which a drug is excreted by the kidneys
, D. The percentage of the drug that reaches systemic circulation
Answer: A
Conceptual Explanation: The therapeutic index (TI) is a measure of drug safety,
calculated as the ratio of the dose that produces toxicity to the dose that produces a
clinically desired effect.
5. Which pregnancy category indicates that studies in animals or humans have demonstrated
fetal abnormalities and the risk outweighs any benefit?
A. Category X
B. Category C
C. Category D
D. Category B
Answer: A
Conceptual Explanation: Category X signifies that the drug is contraindicated in women
who are or may become pregnant due to proven fetal risks.
6. How many half-lives does it typically take for a drug to reach a steady-state concentration
in the plasma?
A. 1 to 2
B. 8 to 10
C. 4 to 5
