NURS 2042 Exam 3 Autonomic NervousSystem With Complete Solution
Sympathetic nervous system - ANSWER adrenergic agonist and adrenergic
antagonist/blockers
epi, norepi, dopamine
Sympathetic (adrenergic) - ANSWER fight or flight
parasympathetic nervous system - ANSWER cholinergic agonist and
anticholinergics
acetylcholine
parasympathetic (cholinergic) - ANSWER rest and digest
Epinephrine affects - ANSWER heart; increase HR, increase BP, and increase
blood sugar
Norepinephrine affects - ANSWER vessels; increase HR, increase BP, and
increase blood sugar
Dopamine affects - ANSWER movement and emotional response, also mood
control
Adrenergic receptors - ANSWER alpha, beta 1, beta 2, dopaminergic
Alpha = - ANSWER tissues, muscles, organs
Alpha causes - ANSWER vasoconstriction, decreased GI motility, uterine
contraction, dilated pupils, gluconeogenesis
Beta 1 = - ANSWER Heart
,Beta 1 causes - ANSWER increased contractility, increase HR, increase uterine
relaxation
Beta 2 = - ANSWER Lungs
Beta 2 causes - ANSWER dilation of bronchioles, gluconeogenesis, decreased
motility, resp. dilation
Dopaminergic = - ANSWER vessel dilation
Nicotinic = - ANSWER ganglia
Nicotinic causes - ANSWER increased HR, increased BP, pupil constriction,
increased tone & motility of GI/GU, relaxed sphincter, increased muscle
contraction, memory
Muscarinic = - ANSWER organs
Muscarinic causes - ANSWER increased secretions, decreased HR, decreased
BP, pupil constriction, increased tone & motility GI/GU, relaxed sphincter,
memory
Adrenergic indications - ANSWER Respiratory (asthma), nasal decongestant,
eye (glaucoma), bladder (relax muscles & help hold more), heart (HF or
shock)

receptors
movement & mood control
Dopamine Low Dose - ANSWER increased blood flow to brain, heart, kidneys,
and mesentery (GI)= Dopaminergic
