Question 1 (MCQ)
Clinical Scenario
A newly licensed nurse is preparing medications for several
patients. During orientation, the preceptor emphasizes that
nurses should understand the difference between a
medication's generic name, trade name, pharmacologic
classification, and therapeutic classification before
administering medications safely.
Question Stem
Which statement best describes the relationship among the
four basic pharmacology terms?
Answer Options
A. A drug's therapeutic classification describes how the drug
works at the cellular level.
B. The generic name is assigned by the manufacturer for
marketing purposes.
C. A pharmacologic classification groups drugs according to
their mechanism of action or effects on body systems.
,D. The trade name is standardized internationally and cannot
vary among manufacturers.
Correct Answer
C. A pharmacologic classification groups drugs according to
their mechanism of action or effects on body systems.
Detailed Rationale
Pharmacology uses several basic terms that help healthcare
professionals communicate accurately and safely.
• Generic name: Official nonproprietary name assigned to
the medication.
• Trade (brand) name: Proprietary name selected by the
manufacturer.
• Therapeutic classification: Describes the clinical purpose
or therapeutic use of the medication (e.g.,
antihypertensive).
• Pharmacologic classification: Describes the mechanism of
action or physiologic effects (e.g., ACE inhibitor).
Understanding these distinctions improves medication safety,
facilitates communication among healthcare providers, and
supports evidence-based medication selection.
, Incorrect Option Analysis
Option A
Why Incorrect
Therapeutic classification describes what the drug is used for,
not its mechanism.
Common Clinical Misconception
Students often confuse therapeutic effects with pharmacologic
mechanisms.
Medication Safety Risk
Misinterpreting drug classes may result in selecting
inappropriate medications.
Nursing Consideration
Understand both therapeutic purpose and pharmacologic
mechanism before administration.
Option B
Why Incorrect
The generic name is assigned as the official nonproprietary
name, not by manufacturers for marketing.
