NSG 318 Final Exam – GCU Pharmacology – 2026 Practice Questions & Answers
Part 1: Fundamentals of Pharmacology (Questions 1-25)
1. Which term describes the study of how the body affects a drug (absorption,
distribution, metabolism, excretion)?
A) Pharmacodynamics
B) Pharmacokinetics
C) Pharmacogenomics
D) Pharmacoepidemiology
Answer: B) Pharmacokinetics
Rationale: Pharmacokinetics covers the four processes of ADME—how the body
handles a drug. Pharmacodynamics is the study of how the drug affects the body .
,2. A drug that binds to a receptor and produces the same response as the
endogenous ligand is a:
A) Antagonist
B) Partial agonist
C) Full agonist
D) Inverse agonist
Answer: C) Full agonist
Rationale: Full agonists produce maximal receptor response similar to the natural
ligand. Antagonists block receptors without activating them .
3. Which route of administration typically provides the fastest onset of action?
A) Oral
,B) Intramuscular
C) Intravenous
D) Subcutaneous
Answer: C) Intravenous
Rationale: IV administration delivers the drug directly into the bloodstream,
bypassing absorption barriers and providing immediate onset of action .
4. A competitive antagonist at a receptor:
A) Permanently deactivates the receptor
B) Can be overcome by increasing agonist concentration
C) Produces the same effect as an agonist
, D) Enhances receptor sensitivity
Answer: B) Can be overcome by increasing agonist concentration
Rationale: Competitive antagonists bind reversibly to receptors. Higher
concentrations of agonist can outcompete the antagonist for receptor binding
sites .
5. Which is an example of a generic drug?
A) Claritin
B) Tylenol
C) Aspirin
D) Acetaminophen
Answer: D) Acetaminophen
