NSG 6435 FINAL EXAM 2 2026 ACTUAL EXAM
PAPER COMPLETE QUESTIONS AND ANSWERS
GRADED A+
◉ Alpha1 receptors. Answer: Causes vasoconstriction which leads to
an increase in blood pressure; Dilates pupils, decreases salivary
glands (dry mouth)
◉ Alpha2 receptors. Answer: Inhibit the release of norepinephrine
which causes a decrease in vasoconstriction which leads to a
decrease in blood pressure; Decreased GI motility (constipation)
◉ Beta1 receptors. Answer: Increase contractility and heart rate
◉ Beta2 receptors. Answer: Causes relaxation of the smooth muscle
in the lungs which leads to bronchodilation
Increased blood glucose
Decrease in GI tone and motility (Constipation)
Relaxation of the uterine muscle (Stop premature labor)
◉ Direct-acting sympathomimetics. Answer: Directly stimulate the
adrenergic receptor (epinephrine and norepinephrine)
,◉ Indirect-acting sympathomimetics. Answer: Stimulate the release
of norepinephrine from the terminal nerve endings (amphetamine)
◉ Mixed-acting sympathomimetics. Answer: Stimulate the
adrenergic receptor sites and stimulate the release of
norepinephrine (ephedrine)
◉ Catecholamines. Answer: Chemical structures of a substance that
can produce a sympathomimetic response; Quickly metabolized so
must be given by injection endogenous: epinephrine,
norepinephrine, and dopamine
Synthetic: Isoproterenol and dobutamine
◉ Noncatecholamines. Answer: Stimulate the adrenergic receptors
Phenylephrine, albuterol, metaproterenol
Have a longer duration of action than endogenous and synthetic
◉ Nonselective. Answer: Affects different adrenergic receptors
◉ Adrenergic antagonists, adrenergic blockers, sympatholytics.
Answer: Drugs that block the effects of adrenergic
neurotransmitters
Block by occupying the receptors or by inhibiting the release of
neurotransmitters norepinephrine and epinephrine
, ◉ Alpha-adrenergic antagonists. Answer: Drugs that block or inhibit
a response at the alpha-adrenergic receptor sites
Selective:
◉ Cholinergic agonists, muscarinic agonists,
parasympathomimetics. Answer: Stimulate the parasympathetic
nervous system by mimicking the neurotransmitter acetylcholine
◉ Cholinergic antagonists, muscarinic antagonists,
parasympatholytics, anticholinergics. Answer: Drugs that inhibit the
actions of of acetylcholine by occupying the acetylcholine receptors
◉ Muscarinic receptors. Answer: Stimulates smooth muscle and
slows the heart rate
◉ Nicotinic receptors. Answer: Affects the skeletal muscles
◉ Direct-acting cholinergic agonists. Answer: Act on receptors to
activate a tissue response
◉ Indirect-acting cholinergic agonists. Answer: Inhibits the action of
AChE which allows ACh to persist and attach to the receptor
