NUR 3128 Module 13 Final Exam Questions and Answers

___ is calculated by multiplying the heart rate in beats per minute (beats/min) by the stroke volume (volume of blood ejected during systole) in liters per beat ~ Cardiac output The factors that determine ___ are (1) preload, (2) afterload, (3) myocardial contractility, and (4) heart rate. Preload, afterload, and contractility all affect stroke volume ~ cardiac output ___ is the volume and pressure inside the ventricle at the end of diastole Described in two ways •ventricular end-diastolic volume [VEDV] •ventricular end-diastolic pressure [VEDP]. ~ Preload ___ is determined by two primary factors: •the amount of blood left in the ventricle after systole (end-systolic volume) •the amount of venous blood returning to the ventricle during diastole. ~ Preload -Ventricular ___ is the resistance to ejection of blood from the ventricle. -It is the load the muscle must move during contraction. -The aortic systolic pressure is an index of ___. (ex. SBP) -Pressure in the ventricle must exceed the aortic pressure before blood can be pumped out during systole. ~ afterload •Affects cardiac output •Pressure in aorta that must be overcome before blood is ejected from left ventricle •Lowering
