CCRN-K Cardiac Review UPDATED
ACTUAL Exam Questions and CORRECT
Answers
CO - CORRECT ANSWER - The volume of blood ejected from the heart in 1 minute



CO (derived parameter) - CORRECT ANSWER - HR x SV



CI (derived parameter) - CORRECT ANSWER - CO/BSA



Normal CI - CORRECT ANSWER - 2.5-5.3 L/m2/minute



Determinants of Stoke volume - CORRECT ANSWER - Preload, afterload and
contractility


Preload defined - CORRECT ANSWER - volume of blood in the ventricle at end-diastole



CVP - CORRECT ANSWER - Normal 0-5 mmHg Optimized 0-10 mmHg



Pulmonary Artery Occlusion Pressure - CORRECT ANSWER - 6-12 mmHg Optimized
would be 14-18 mmHg


Dynamic Parameters - CORRECT ANSWER - SVV PPV and SPV predict preload
responsiveness <13%: Respond to Fluid


SVV - CORRECT ANSWER - Stroke volume variation



PPV - CORRECT ANSWER - Pulse pressure variation

, SVR formula - CORRECT ANSWER - 80 (MAP-RAP)/CO



SVR Parameters - CORRECT ANSWER - 800-1200 dynes/sec/cm5
SVRI: 1970-3900 dynes/sec/cm5/m2


PVR - CORRECT ANSWER - 80 (MPAP-PaOP)/CO



Normal PVR/PVRI - CORRECT ANSWER - <250 dynes/sec/cm5
Indexed: 255-285


What can you use as a surrogate for PAOP? - CORRECT ANSWER - PADP as long as
they are within 1-5 mmHg of each other


Hemodynamic Assessment of Contractility - CORRECT ANSWER - LVSWI & RVSWI
these parameters good for titrating inotropes/pressors or loading with beta blocker for
hyperdynamic heart


LVSWI (derived parameter) - CORRECT ANSWER - SVI(MAP-PaOP) x 0.0136



RVSWI (derived parameter) - CORRECT ANSWER - SVI(MAPAP-RAP) x 0.0136



PULMONARY ARTERY PRESSURE - CORRECT ANSWER - 15-25 Systolic . 6-12
Diastolic


Pulmonary artery occlusion pressure (PAOP) - CORRECT ANSWER - 6-12 mmHg



Calculating MAP - CORRECT ANSWER - Systolic BP + 2(DBP)/3 = MAP
