afterload)
Dobutamine mechanism of action - ANS-contractility
Dopamine at a low-end dose "renal dose" - ANS-0.5-4mcg/kg/min
increases renal and mesentric perfusion
Dopamine at a mid-range dose - ANS-4-10mcg/kg/min
increases contractility and heart rate
Dopamine at a high-range dose - ANS-greater than 10mcg/kg/min
vasoconstriction and increases BP
Dopamine and Levophed infiltration - ANS-leads to tissue necrosis
Dopamine antidote - ANS-regitine (phentolamine)
TpA monitor for - ANS-bleeding-hemorrhagic CVA
diltiazem (cardizem) works by? - ANS-(calcium channel blocker) slows ventricular rate
by slowing conduction through the SA and AV node

diltazem is used for patients with - ANS-a-fib or a-flutter
amiodarone (Cordarone) is a - ANS-antiarrythmic
prolongs the cardiac duration

Atropine is given to treat? - ANS-symptomatic bradycardia
Dilantin is given to treat - ANS-seizure disorders
DO NOT give __________ with dilantin because ________ will happen. - ANS-DO NOT
give with dextrose containing solutions because it will crystalize
