CVICU review Exam Questions
and Answers 100% Pass
Dobutrex (dobutamine) - CORRECT ANSWER-Inotrope
What is dobutrex primarily used for? - CORRECT ANSWER-to help increase
contractility and increase CO/CI
What is the starting dose of dobutrex? - CORRECT ANSWER-2-5 mcg/kg/min
What is dobutrex mechanism of action? - CORRECT ANSWER-stimulates beta-
receptors of the heart which produces increased cardiac output and mild
chronotropic, vasodilative, and arrythmogenic effects
What is dobutrex expected effects on hemodynamics? - CORRECT ANSWER-
increase HR, increase BP, increase CO/CI, decrease SVR
What are the order comments for dobutrex? - CORRECT ANSWER-titrate 1-10
mcg/kg/min per effect prn unstable hemodynamics-- use if cardiac output low,
with high SVR and normal HR
Primacor (Milrinone) - CORRECT ANSWER-phosphodiesterase inhibitor
, what is the mechanism of action of primacor? - CORRECT ANSWER-increse of
intracellular ionized calcium and contractile force in heart muscles. decreased
amount of calcium available for smooth muscle, leading to vasodilation.
what drug may be needed when giving primacor? - CORRECT ANSWER-levo
due to profound hypotension with low SVR
dosing for primacor - CORRECT ANSWER-bolus: 50mcg/kg over 10- 20 min
followed by infusion
infusion: 0.1-0.75 mcg/kg/min
titrate only with physicians orders
primacor effects on hemodynamics - CORRECT ANSWER-decrease BP, increase
CO/CI, decrease SVR
primacor order comments - CORRECT ANSWER-titrate 0.25-0.5 mcg/kg/min
check with physician before starting
what is primacor primarily used for? - CORRECT ANSWER-to help increase
squeeze (contractility) and increase cardiac index
Epinephrine - CORRECT ANSWER-cardiac stimulant, bronchodilator,
vasopressor
Epi Mechanism of Action - CORRECT ANSWER-sympathomimetic
catecholamine that acts on both alpha and beta adrenergic receptors. result is
