Question 1 (MCQ)
Clinical Scenario
A nurse is caring for a patient who has just started an oral
antihypertensive medication. During discharge teaching, the
patient asks, "How will I know if this medicine is working?"
Question Stem
Which response by the nurse best explains the therapeutic
effect of a medication?
Answer Options
A. It is any unintended response that occurs after taking a
medication.
B. It is the desired physiologic response for which the
medication is prescribed.
C. It is the maximum amount of medication the body can
tolerate.
D. It is the rate at which the kidneys eliminate a medication.
Correct Answer
B
,Detailed Rationale
The therapeutic effect is the intended, beneficial physiologic
response produced by a medication. For an antihypertensive,
this would include lowering blood pressure and reducing the
risk of cardiovascular complications. Nurses evaluate whether
the therapeutic objective has been achieved while also
monitoring for adverse effects.
Incorrect Option Analysis
A
• Why Incorrect: Describes an adverse effect rather than a
therapeutic effect.
• Common Misconception: Any response to medication is
therapeutic.
• Medication Safety Risk: Patients may ignore harmful
symptoms.
• Nursing Consideration: Teach patients to distinguish
expected benefits from adverse reactions.
C
• Why Incorrect: Refers to toxicity rather than therapeutic
action.
• Common Misconception: Therapeutic effect depends only
on dose size.
, • Medication Safety Risk: Patients may self-adjust doses.
• Nursing Consideration: Reinforce adherence to prescribed
dosing.
D
• Why Incorrect: Describes elimination, a pharmacokinetic
process.
• Common Misconception: Drug elimination determines
therapeutic effect.
• Medication Safety Risk: Confusing pharmacokinetics with
pharmacodynamics.
• Nursing Consideration: Explain that drug effects depend
on multiple factors.
