Question 15

epinephrine

Answer 15

alpha, beta 1, beta 2 agonist

Question 16

adverse effects of Phenylephrine

Answer 16

constipation, HTN, bradycardia (reflexive b/c of HTN), urinary retention

Question 17

Phentolamine/ Prazosin adverse effects

Answer 17

tachyardia, weakness dizziness, flushing, orthostatic hypotension, nasal congestion (alpha antagonist effects)

Question 18

isoproterenol 1,2 / Dobutamine adverse effects

Answer 18

serious –> ventricular arrhythmia, tacharryhtmia, HTN, pulmonary edema
common –> tachycardia, angina, dizzy/flush, orthostatic hypotension, nasal congestion (Beta agonist functions)

Question 19

Atenolol, Propranolol adv effects

Answer 19

bradycardia (vasoconstriction -reflex), exacerbate asthma
serious -> CHF, bentricular arrhythmia, severe bradycardia, MI if abrupt d/c, Raynaud’s syndrome (compensatory vasoconstriction) bronchospasm (Beta antagonist)

Question 20

Epi, Nor epi adv effects

Answer 20

severe HTN, bradycardia (common - reflex) exacerbate asthma, extrvasational necrosis, bronchospasm, cold extremities, dyspnea

Question 21

Bethanechol

Answer 21

M agonist

Question 22

Atropine

Answer 22

M antagonist

Question 23

Bethanechol indications

Answer 23

urinary retention and ileus

Question 24

Atropine indications

Answer 24

bradycardia, aspiration prophylaxis, block cardio vagal response

Question 25

Bethanechol adverse effects

Answer 25

bronchospasm, HYPOtension, tachycardia (reflexive)

other -> urinary urgency, vasomotor response, diarrhea, diaphoresis

Question 26

Atropine adverse effects

Answer 26

heatstroke, tachycardia, xerostomia (dry mouth), constipation, dry hot skin

Question 27

pt comes in w/ MI and bradycardia and left arm pain –> pop them w/ atropine, what do you look for?

Answer 27

if heart activity comes back to normal, will prove they were suffering from over active vagal nerve –> (parasympathetic inhibition of cardiac action)
