1. Anterior infarction: ST elevation, Leads V1, V2, V3, V4 with or without abnormal Q waves Usually associated with occlusion of the LAD branch of the LCA 2. Lateral infarction: ST elevation, Leads I, aVL, V5, V6 with or without abnormal Q waves May be a component of a multiple site infarction Usually associated with obstruction of Left circumflex artery 3. Inferior infarct: ST elevation, Leads II, III, aVF with or without abnormal Q wave Usually associated with RCA occlusion 4. Right Ven...

minimum urine output for adult 0.5mL/kg/hr ADH (antidiuretic hormone) - water retainer - vasoconstrictor (also called Vasopressin) - produced by hypothalamus - store and released from posterior pituitary ADH pathway - hypothalamus senses low blood volumed and increased serum osmolality - signal pituitary to release ADH - ADH causes kidney to retain water - water retention increases blood volume and decreases serum osmolality ANP (atrial natriuretic peptide) -...

A branch of the _______________ supplies the right atrium and right ventricle with blood. correct answer: right coronary artery (RCA) Stimulation of parasympathetic nerve fibers typically results in which of the following actions? correct answer: Slowed conduction through the atrioventricular (AV) node The contribution of blood that is added to the ventricles and results from atrial contraction is called correct answer: atrial kick. Which of the following are semilunar valves? correc...

What are the 6 parts of the cardiac conduction cycle? correct answer: -SA node -Internodal pathways -AV node -Bundle of His -R and L bundle branches -Purkinje fibers What is the SA node? correct answer: -Small cluster of cells located in the upper R atrium *-Pacemaker of the heart* What are internodal pathways? correct answer: Impulses sent by the SA node that travel through the atrial muscle fibers via the intra-atrial pathways Allows for simultaneous depolarization and contra...

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...
