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...
