WGU D116 Pharm Unit 4 Cardio Questions And Answers Rated A+ Blood flow ANS Resistance: vessel diameter, vessel length, blood viscosity Back to heart: negative pressure in right atrium sucks in blood, constriction of muscle in vein wall, valves and skeletal muscles Stroke Volume (SV) ANS measurement of the amount of blood ejected from a ventricle in one contraction 1-myocardial contractility 2-cardiac afterload 3-cardiac preload Can be increased by SNS through beta 1 receptors Preloa...

Compliance (Cardiac Vocabulary) - Answer the "stretch ability" of the myocardial walls ex. how well stretch and contract like a squishy or hard ball Elasticity (Cardiac Vocabulary) - Answer the ability of the myocardial wall to return to its original shape "snapback" Contractility (Cardiac Vocabulary) - Answer the force of the contraction generated by the myocardium Pre-load - Answer the maximum degree of stretch of the myocardial muscle fibers just before cont...

NRSG 3100 Exam Questions with complete solution NRSG 3100 Exam #4 Ventricular pulse rate - correct answer 40-30 AV pacer rate - correct answer 60-405 What is makes up stroke volume - correct answer preload, afterload, and contractility Normal stroke volume - correct answer 60-70% TTE vs TEE - correct answer transthoracic vs transesophageal echocardiogram. TEE is more sensitive and accurate for finding vegetations preload - correct answer Degree of stretch of the v...

contractility - strength of contraction -how effective is heart at squeezing blood out improving contractility - BP is low-> give catelcholamines depressing contractility - BP is high-> beta blockers preload - degree of stretch at END of diastole (relax so filling) -higher stroke volume= more blood returning to heart afterload - resistance of ejecting blood out from ventricle s -more resistance- less stroke volume -vessels dilated- less resistance- easier to leave heart increasing...

The degree of stretch at the end of diastole (how much blood is in the ventricles) is known as - Preload An increase in fluids will __________ preload, and a decrease in fluids will ___________ preload - An increase in fluids will increase preload, and a decrease in fluids will decrease preload The resistance to eject blood from the ventricles is known as - Afterload Hypertension and vasoconstriction have what effect on Afterload? - HTN and vasoconstriction will INCREASE afterload (increa...

preload - degree of stretch (volume of blood) of the ventricular muscle fibers at the end of diastole (when filling volume is the greatest). the higher this is the stronger the contraction preload - increased by blood transfusions, IV fluids, hypervolemia, regurgitation preload - decreased by hemorrhage, diuresis, dehydration, vasodilation afterload - resistance to ejection of blood from the ventricles afterload - increased by htn and vasoconstriction afterload - decreased by nitroglyceri...
