NSG 318 Exam 2 Frequently Tested Actual Questions and
Answers
Question 1.
Adrenergic agonists, adrenergics, sympathomimetics
Correct Answer: Drugs that stimulate that sympathetic nervous system by
mimicking epinephrine and norepinephrine Act on one or more adrenergic
receptor sites
Question 2.
Alpha1 receptors
Correct Answer: Causes vasoconstriction which leads to an increase in blood
pressure; Dilates pupils, decreases salivary glands (dry mouth)
Question 3.
Alpha2 receptors
Correct Answer: Inhibit the release of norepinephrine which causes a decrease
in vasoconstriction which leads to a decrease in blood pressure; Decreased GI
motility (constipation)
Question 4.
Beta1 receptors
Correct Answer: Increase contractility and heart rate
Question 5.
Beta2 receptors
Correct 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)
Question 6.
Direct-acting sympathomimetics
Correct Answer: Directly stimulate the adrenergic receptor (epinephrine and
norepinephrine)
, Question 7.
Indirect-acting sympathomimetics
Correct Answer: Stimulate the release of norepinephrine from the terminal
nerve endings (amphetamine)
Question 8.
Mixed-acting sympathomimetics
Correct Answer: Stimulate the adrenergic receptor sites and stimulate the
release of norepinephrine (ephedrine)
Question 9.
Catecholamines
Correct 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
Question 10.
Noncatecholamines
Correct Answer: Stimulate the adrenergic receptors Phenylephrine, albuterol,
metaproterenol Have a longer duration of action than endogenous and synthetic
Question 11.
Nonselective
Correct Answer: Affects different adrenergic receptors
Question 12.
Adrenergic antagonists, adrenergic blockers, sympatholytics
Correct Answer: Drugs that block the effects of adrenergic neurotransmitters
Block by occupying the receptors or by inhibiting the release of
neurotransmitters norepinephrine and epinephrine
Question 13.
Alpha-adrenergic antagonists
Correct Answer: Drugs that block or inhibit a response at the alpha-adrenergic
receptor sites Selective:
