Questions With Correct 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

dizziness, hypotension
Angiotensin II Receptor Blockers contraindications - answer✔PARK: pregnancy, angioedema /
allergy; renal failure, hyperkalemia
Angiotensin II Receptor Blockers nursing process - answer✔assess potassium level; avoid
grapefruit juice
Calcium Channel Blockers additive effects - answer✔Additive effects with beta blockers (avoid
grapefruit juice)
Calcium Channel Blockers uses - answer✔angina, hypertension, SVT, headaches, a-fib
Vasodilators; uses, names - answer✔Hypertension; hydralazine, diazoxide, minoxidil
Carbonic Anhydrase Inhibitors - answer✔Acetazolamide; treat glaucoma, edema.

Loop diuretics (hate everyone, waste all electrolytes): names and MOI - answer✔Furosemide,
torsemide, bumetanide: prevent re-absorption of sodium and water in loop of Henle
Loop diuretics uses - answer✔Edema, renal / hepatic disease, hypertension
Loop diuretics adverse effects - answer✔tinnitus, dizziness, hypokalemia, hyperglycemia,
hyperuricemeia
Osmotic Diuretics - answer✔Mannitol; uses: acute kidney injury, reduces ICP, cerebral edema
Osmotic diuretics adverse effects - answer✔seizures, thrombophlebitis
Osmotic Diuretics nursing process - answer✔Send back to pharmacy to be warmed if crystals are
observed
Potassium sparing diuretics (love potassium, hold on to it) MOI; uses - answer✔works in distal
convoluted tubules --> block reabsorption of water; uses: hypertension, HF, edema, PVH
