Question 1 (MCQ)
Clinical Scenario
A nurse is teaching a newly hired graduate nurse about basic
pharmacology terminology. During orientation, the graduate
nurse asks about the difference between a drug's therapeutic
effect and its side effects.
Question Stem
Which statement best describes the therapeutic effect of a
medication?
Answer Options
A. An unintended secondary effect occurring at normal doses
B. The primary beneficial response for which the drug is
administered
C. A toxic response caused by excessive drug accumulation
D. An allergic reaction resulting from immune sensitization
Correct Answer
B. The primary beneficial response for which the drug is
administered
,Detailed Rationale
The therapeutic effect is the intended, beneficial physiologic
response that a medication is prescribed to achieve. Examples
include lowering blood pressure with antihypertensive
medications or reducing pain with analgesics. Understanding
therapeutic effects allows nurses to evaluate treatment
effectiveness and determine whether desired outcomes are
being achieved.
Incorrect Option Analysis
A. Unintended secondary effect
• Why Incorrect: Describes a side effect.
• Common Misconception: Assuming all drug effects are
therapeutic.
• Safety Risk: Failure to monitor adverse effects.
• Nursing Consideration: Educate patients regarding
expected side effects.
C. Toxic response
• Why Incorrect: Describes toxicity.
• Common Misconception: Equating strong therapeutic
effects with toxicity.
• Safety Risk: Delayed recognition of overdose.
, • Nursing Consideration: Monitor drug levels when
indicated.
D. Allergic reaction
• Why Incorrect: Represents hypersensitivity.
• Common Misconception: Confusing adverse reactions with
therapeutic effects.
• Safety Risk: Failure to recognize anaphylaxis.
• Nursing Consideration: Assess allergy history.
