Question 1 (MCQ)
Clinical Scenario
A nurse is caring for a patient who reports that a prescribed
medication consistently lowers blood pressure but occasionally
causes dizziness when standing.
Question Stem
Which pharmacology term best describes the intended
lowering of blood pressure produced by the medication?
Answer Options
A. Toxic effect
B. Therapeutic effect
C. Adverse effect
D. Allergic reaction
Correct Answer
B. Therapeutic effect
,Detailed Rationale
A therapeutic effect is the primary intended beneficial response
for which a medication is prescribed. In this scenario, lowering
blood pressure is the desired clinical outcome.
Therapeutic effects are the foundation of
pharmacotherapeutics and guide evaluation of medication
effectiveness. Nurses must assess whether the expected
therapeutic response occurs while monitoring for adverse
reactions.
Incorrect Option Analysis
A. Toxic effect
Why Incorrect: Toxic effects occur when drug levels become
excessive.
Common Misconception: Any unwanted effect equals toxicity.
Safety Risk: May result in unnecessary withholding of therapy.
Nursing Consideration: Assess severity and medication levels if
toxicity is suspected.
C. Adverse effect
Why Incorrect: Dizziness is an adverse effect, not the intended
blood-pressure reduction.
, Common Misconception: Confusing desired and undesired
effects.
Safety Risk: Inaccurate evaluation of drug effectiveness.
Nursing Consideration: Distinguish therapeutic from adverse
outcomes.
D. Allergic reaction
Why Incorrect: No immune-mediated response is described.
Common Misconception: Any negative symptom is an allergy.
Safety Risk: Inappropriate allergy labeling.
Nursing Consideration: Verify allergy symptoms before
documentation.
