alpha 1 receptors Ans: increase force of contractibility of
heart, increase BP, pupil dilation, bladder contraction, &
© 2026 Assignment
prostate contraction
alpha 2 receptors Ans: inhibits release of norepinephrine,
Guru01 - Stuvia
decrease BP, decrease GI tone and motility
Expert
beta 1 receptors Ans: increase heart rate and force of
contraction, increase BP
beta 2 receptors Ans: decrease GI tone and motility,
bronchodilation, relax uterine smooth muscle, increase blood
sugar
catecholamine action & examples Ans: produce a
sympathomimetic response
ex: epinephrine, norepeinephrine, dopamine (DEN)
epinephrine (Adrenalin) Ans: for emergencies to stimulate
cardiac function and increase BP, used for anaphylaxis, cardiac
arrest, bronchospasm & decreased airflow to lungs-
nonselective
side effects of Adrenalin Ans: anorexia, N/V, nervousness,
tremors, agitation, HA, pallor, insomnia, syncope, dizziness,
tachycardia, dyspnea, adverse pulmonary edema
, 2
response in mainly bronchodilation, less side effects, used to
treat bronchospasms Ans: albuterol (Proventil) S/E- tremors,
restlessness, nervousness w/ high doses, dizziness,
tachycardia, hallucinations
Rx hypertension, alpha 2 drugs Ans: clonidine (Catapress),
methyldopa (Aldomet)
antidote for adrenergic drugs - phenylephrine HC1 (Neo-
Synephrine), pseudoephedrine HC1 (Sudafed), norepinephrine
(Levopled), dopamine HC1 Ans: phentoalmine mesylate

nursing interventions for sympathomimetics/ Adrenomimetics
Expert
Ans: VS, report increase in heart rate or BP, report side
effects, urinary output, give w/ food to prevent N/V, evaluate
blood glucose levels, encourage not to take OTC or herbals,
FOF-3000mL/day
adrenergic agonists (sympathomimetics) -- (mimic
norepinephrine or epinephrine) Ans: act on one or more
adrenergic receptor sites, SMOOTH muscles such as heart,
bronchiole walls, GI tract, urinary bladder and ciliary muscle
of eye *mobilize body for action 'fright/flight/flight
syndrome'*
areas to assess before giving alpha 2 drugs - albuterol,
clonidine, methyldopa Ans: BP, pulse, respirations, lung
sounds
alpha adrenergic blockers Ans: help decrease symptoms of
BPH, decrease BP (not used for this primarily), and *treat
peripheral vascular disease (vasodilation)*
