Question 1 (MCQ)
Clinical Scenario
A nurse is preparing to administer a newly prescribed
medication. Before administration, the nurse reviews the drug's
expected effects, potential adverse effects, and monitoring
requirements.
Question Stem
Which pharmacologic term best describes the study of how
drugs affect the body?
Answer Options
A. Pharmacokinetics
B. Pharmacodynamics
C. Toxicology
D. Pharmacogenomics
Correct Answer
B. Pharmacodynamics
,Detailed Rationale
Pharmacodynamics examines what a drug does to the body,
including mechanisms of action, therapeutic effects, adverse
effects, and toxicity. Understanding pharmacodynamics helps
nurses predict desired and undesired patient responses.
Incorrect Option Analysis
A. Pharmacokinetics
Why Incorrect:
Describes what the body does to the drug (absorption,
distribution, metabolism, excretion).
Common Misconception:
Confusing drug movement with drug action.
Safety Risk:
May impair understanding of medication monitoring.
Nursing Consideration:
Assess factors affecting absorption and elimination.
C. Toxicology
Why Incorrect:
Focuses on harmful effects of chemicals and drugs.
, Common Misconception:
Assuming all adverse effects equal pharmacodynamics.
Safety Risk:
Failure to recognize broader therapeutic actions.
Nursing Consideration:
Monitor for overdose and toxicity.
D. Pharmacogenomics
Why Incorrect:
Studies genetic influences on drug response.
Common Misconception:
Believing genetics explains all drug actions.
Safety Risk:
Overlooking non-genetic factors.
Nursing Consideration:
Consider individualized therapy.
