Exam 2 (71
questions and
answers)
Epinephrine MOA - answer stimulates alpha, beta1, and
beta2 adrenergic receptors; causes pupil dilation,
bronchodilation, increased HR, vasoconstriction, urinary
retention


Epinephrine Contraindications - answer Galucoma, MAOI


Epinephrine extravasation - answer Phentolamine
mesylate


Prazosin: class, use, contraindication - answer Alpha
Blocker; hypertension; additive effect with beta blockers
(causes hypotension)

, Doxazosin: class, use, contraindication - answer Alpha
Blocker; hypertension; additive effect with beta blockers
(causes hypotension)


Tamsulosin: class, use, contraindication - answer Alpha-
Blocker; BPH


Prazosin, Doxazosin patient teaching - answer Do not stop
abruptly. Avoid OTC cold medications. Monitor for ankle
edema. Rise slowly, in stages.


Tamsulosin patient teaching - answer Take in the evening.
Monitor for ankle edema. Avoid OTC cold medication.


Beta blockers - answer End in -olol; used for angina, MI,
hypertension, HF


Beta Blockers MOA - answer Block sympathetic influence
on the heart (esp B1 selective), reducing CO and thus BP;
adrenergic blocking = Pupil constriction,
bronchoconstriction, decreased heart rate, vasodilation,
decreased blood pressure, increase GI activity


Beta-blockers cautions - answer Must be used with
diuretic in African Americans; can mask hypoglycemic
symptoms (causing tachycardia)


ACE inhibitors names / MOI / class - answer END IN -PRIL;
prevents ACE enzyme from converting Angiotensin I to
Angiotensin II / antihypertensive
