Question 1 (MCQ)
Clinical Scenario
A newly licensed nurse is reviewing medication orders before
administering drugs during the first shift on a medical-surgical
unit. The nurse wants to ensure an understanding of the
terminology used in pharmacology.
Question Stem
Which statement best describes the relationship between
pharmacology and therapeutics?
Options
A. Pharmacology focuses on drug preparation, whereas
therapeutics focuses only on medication storage.
B. Pharmacology studies drugs and their interactions with living
systems, whereas therapeutics focuses on the clinical use of
drugs to prevent and treat disease.
C. Pharmacology and therapeutics are identical disciplines.
D. Therapeutics is limited to over-the-counter medications.
,Correct Answer
B
Detailed Rationale
Pharmacology is the scientific study of drugs, including their
sources, properties, mechanisms of action, pharmacokinetics,
pharmacodynamics, therapeutic effects, and adverse effects.
Therapeutics applies this knowledge to prevent, diagnose, and
treat disease while optimizing patient outcomes. Nurses rely on
both disciplines to administer medications safely, evaluate
therapeutic responses, recognize adverse reactions, and
educate patients.
Incorrect Option Analysis
A
Why Incorrect
Drug preparation is only one aspect of medication management
and does not define pharmacology.
Common Misconception
Confusing pharmacology with pharmacy practice.
Medication Safety Risk
, Incomplete understanding may lead to poor medication
assessment.
Nursing Consideration
Recognize that pharmacology includes drug actions and patient
responses.
C
Why Incorrect
Therapeutics is one application of pharmacologic knowledge.
Common Misconception
Assuming both terms are interchangeable.
Medication Safety Risk
Failure to distinguish drug science from clinical application.
Nursing Consideration
Understand both concepts to improve medication decision-
making.
