CCRN- Hemodynamics Concepts (Barron's) questions with correct answers

HR x SV= CO CORRECT ANSWER-what is the calculation for cardiac output?*** 1) preload 2) afterload 3) contractility CORRECT ANSWER-what are 3 things that the SV is dependent upon? 1) CVP; right ventricular 2) PAOP (pulmonary artery occlusive pressure); left ventricular CORRECT ANSWER-the preload affects what two measurements of the heart? 1) PVR (pulmonary vascular resistance); right ventricular 2) SVR (systemic vascular resistance); left ventricular CORRECT ANSWER-the afterload affects what two measurements of the heart? 4L-8L -if CO becomes critically low, the BP will decrease CORRECT ANSWER-what is the normal CO? cardiac index CORRECT ANSWER-this measurement takes into account the body surface area (BSA) and is A MORE MEANINGFUL VALUE THAN CO 2.5 to 4.0L/min/m2 CORRECT ANSWER-what is the normal values of CI?
