1. Which statement by a nursing student best describes
pharmacology?
A. "Pharmacology is the study of disease prevention."
,B. "Pharmacology is the study of drugs and their effects on
living organisms."
C. "Pharmacology focuses only on prescription medications."
D. "Pharmacology is the study of surgical interventions."
Correct Answer: B
Rationale:
Pharmacology is the study of drugs and how they affect living
organisms, including therapeutic effects, adverse effects,
mechanisms of action, and safe administration. Nurses use
pharmacology knowledge to promote medication safety and
effective patient care.
Why the Other Options Are Incorrect:
A: Disease prevention is part of public health, not the
definition of pharmacology.
C: Pharmacology includes prescription, over-the-counter,
herbal, and biologic agents.
D: Surgical interventions are outside the scope of
pharmacology.
Learning Objective: Define pharmacology and its relevance to
nursing practice.

2. A nurse is teaching a patient about sources of medications.
Which medication is an example of a synthetic drug?
A. Digoxin derived from foxglove plants
B. Penicillin produced by mold
C. Acetaminophen manufactured in a laboratory
D. Insulin extracted from animal pancreas tissue

Phase I studies involve a small number of healthy volunteers
and focus on determining safety, dosage ranges,
pharmacokinetics, and initial side effects before the drug is
tested in larger patient populations.
