MAP calculation - [( 2xDBP) + SBP] / 3 cushing's triad - widened pulse pressure, bradycardia, and irregular respirations (indicative of increased ICP) chronotropes - affect the heart rate at the SA node (cardizem) inotropes - affect contractility (dopamine) dromotropes - affect automaticity of the heart ACE inhibitors adverse effects - dry cough, angioedema, renal impairment ARB (sartans) - block angiotensin 2 receptors, resulting in vasodilation antidote for vasopressor e...

CEN Latest Study Guide with Correct Answers 2024 Cardiac Output Correct Answer: amount of blood ejected from the left ventricle each minute-normal cardiac output is 4-8 L per a minute Stroke Volume Correct Answer: The amount of blood ejected from the left ventricle with each contractions; normal is 50-100 mL/ contraction Preload Correct Answer: Amount of blood going into the heart. Right ventricle-assess JVD, Left ventricle- Assess lung sounds Afterload Correct Answer: The pressure...

CEN - CARDIAC REVIEW EXAM REVIEW QUESTIONS AND ANSWERS, RATED A+ Atropine has what affect on the heart - -reverses cholinergic-mediated decrease in heart rate (increases heart rate) Describe afterload - -The pressure the heart must eject against in the aorta measured by blood pressure, specifically MAP (mean arterial pressure) Describe Mobitz Type I - -PR interval gets longer and longer until and QRS complex is dropped. Describe Mobitz Type II - -PR interval remains normal at 0.12 and ...

Cardiac output = - CO + HR x stroke volume (amount of blood ejected per contraction) Primary compensatory mechanism of low Cardiac output in peds? Other signs? - Tachycardia -- Peds are unable to increase stroke volume. Hypotension is a late sign, and bradycardia is an ominous sign in peds. Stroke Volume is influenced by... - Contractility, preload, and afterload. Frank-Starling's Law -- Stretch heart with volume to increase contractility (rubber band snapping shut) Preload is eval...

Mean Arterial Pressure correct answer average pressure over entire cardiac cycle, better indicator of perfusion compared to BP, maintain above 60 mm Hg (SBP+ [DBPx2])/3 Pediatric bolus correct answer 10 ml/kg narrowing pulse pressure correct answer low systemic pressure, r/t blood loss, decreased stroke volume widening pulse pressure correct answer high systemic pulse pressure, may be transient and normal after exercise, caused by chronic (arterial disease) and acute conditions (aortic...
