NSG 145 Practice Exam Questions and
Correct Answers
Explain the interdisciplinary nature of pharmacology, giving an example of how
knowledge from different sciences impacts the nurse's role in drug administration.
✅Knowledge on anatomy, physiology, chemistry, biology and other sciences are
needed in pharmacology, as many different factors can affect the way a drug works.
Knowledge on anatomy helps us determine the best route for administration where
knowledge on chemistry helps us understand how two drugs will interact with each
other.
What is category A of the teratogenic drug classification? ✅Controlled studies in
women fail to show a risk to the fetus, and the
possibility of fetal harm appears unlikely
What is category B of the teratogenic drug classification? ✅Animal reproduction
studies have not shown a fetal risk or adverse effect. Risks have not been
confirmed in controlled studies in women
What is category C of the teratogenic drug classification? ✅Either studies in animals
have revealed adverse effects on the fetus and there are no controlled studies
What is category D of the teratogenic drug classification? ✅There is confirmation of
human fetal risk, but the
benefits from use in pregnant women may be
acceptable despite the risk
What is category X of the teratogenic drug classification? ✅Animal and human studies
have shown fetal abnormalities. -The drug is contraindicated in women who are or may
become pregnant

microorganisms, or by the body itself

Explain the basis for placing drugs into therapeutic and pharmacologic classes
✅Therapeutic classification
• Based on therapeutic usefulness in treating particular diseases or disorders
• Examples: - Antidepressants - Antipsychotics - Antineoplastics
Pharmacologic classification
• Based on the way a drug works at the molecular, tissue, or body system level
• Addresses a drug's mechanism of action
- How a drug produces its physiological effect in the body
• Examples: - Calcium channel blockers - Diuretics - Adrenergic antagonists
What is Mechanism of Action? ✅how a drug produces its physiologic effect on the
body.
Examples from book below
Blocks hormonal activity (blocks intermediates of the angiotensin-renin pathway)
Angiotensin-converting enzyme inhibitor
Blocks physiological reactions to stress
Adrenergic antagonist
Dilates peripheral blood vessels
Vasodilator
