Nitroprusside purpose - Answer- decreases preload and afterload by vasodilation (mainly afterload) Dobutamine mechanism of action - Answer- contractility Dopamine at a low-end dose "renal dose" - Answer- 0.5-4mcg/kg/min increases renal and mesentric perfusion Dopamine at a mid-range dose - Answer- 4-10mcg/kg/min increases contractility and heart rate Dopamine at a high-range dose - Answer- greater than 10mcg/kg/min vasoconstriction and increases BP Dopamine and Levophed inf...

Comprehensive CRNA Interview Review Accurate responses are given. Comprehensive CRNA Interview Review Norepinephrine Mechanism of Action (MOA) A1, A2, B1 agonist. Primary agent used in distributive shock because it's ability to recruit venous volume and augment preload, while increasing arterial tone, and increasing cardiac output. Alpha one causing peripheral smooth muscle contraction. (low dose venous, high dose venous and arterial). Alpha 2 adrenoreceptor agonism actually ant...
