QUESTION 1 — MCQ
Clinical Scenario
A nurse is teaching newly hired nurses about the four basic
pharmacologic terms. One nurse asks how a drug's action
differs from its effect.
Question Stem
Which statement best describes the difference between drug
action and drug effect?
Options
A. Drug action refers to patient response, whereas drug effect
refers to receptor binding.
B. Drug action describes what the drug does to the body,
whereas drug effect describes the body's response.
C. Drug action refers to metabolism, whereas drug effect refers
to elimination.
D. Drug action and drug effect mean the same thing.
Correct Answer
,B
Detailed Rationale
Drug action describes the physiologic or biochemical interaction
between a drug and the body, such as receptor activation or
enzyme inhibition. Drug effect refers to the resulting physiologic
change observed in the patient.
Understanding these concepts assists nurses in predicting
therapeutic responses and adverse effects.
Incorrect Option Analysis
A
• Incorrect because the definitions are reversed.
• Misconception: patient response equals action.
• Safety risk: inability to predict drug effects.
• Nursing consideration: connect mechanism to outcomes.
C
• Confuses pharmacokinetics with pharmacodynamics.
• Safety risk: misunderstanding medication monitoring.
D
, • Action and effect are related but distinct concepts.
