NUR2407 - DRUG ACTIONS AND DEFINITIONS
EXAM QUESTIONS AND ANSWERS UPDATED
(2024/2025) (VERIFIED ANSWERS)
1st generation antipsychotics - ANS ✓Blocks dopamine, acetylcholine,
histamine, and norepinephrine receptors in the brain and periphery
2nd generation antipsychotics - ANS ✓Blocks serotonin & dopamine receptors.
Also block norepinephrine, histamine, and acetylcholine.
3rd generation antipsychotics - ANS ✓Stabilizes dopamine systems agonist
and antagonist
Cholinesterase Inhibitors uses - ANS ✓Tx glaucoma, Alzheimer, Parkinson’s,
reversal for muscarinic antagonists, & reversal of depolarizing neuromuscular
blocking agents
cholinesterase inhibitor - ANS ✓prevent cholinesterase from inactivating
acetylcholine, increasing nerve impulses (parasympathetic response)
Muscarinic - ANS ✓Induces a parasympathetic response
adrenergic agonists - ANS ✓Stimulate alpha 1, beta 1, and beta 2 receptors

alpha 1 receptors purpose - ANS ✓pupil dilation, vasoconstriction
beta 1 receptors purpose - ANS ✓increase HR, increase myocardial
contractility, increase conduction of AV node
beta 2 receptors purpose - ANS ✓vasodilation heart, lungs, & skeletal muscles,
uterine smooth muscle relaxation, activation of liver glycogenolysis, muscle
contraction
muscarinic antagonists - ANS ✓Blocks acetylcholine and produces a
sympathetic response
Non-barbiturate anxiolytic (atypical antidepressant) - ANS ✓inhibit
norepinephrine and dopamine reuptake
Acetylcholine (ACh) - ANS ✓neurotransmitter that stimulates muscle
contractions (skeletal, smooth, and cardiac)
Adrenergic Antagonists - ANS ✓act by directly blocking adrenergic receptors
and producing a parasympathetic response
adrenergic neuron antagonists - ANS ✓Block the release of norepinephrine
from sympathetic neurons
