CCRN AACN Exam Questions With 100% Correct Answers 2023, Exams of Advanced Education

A comprehensive overview of key cardiac hemodynamic concepts and parameters that are essential for critical care nursing practice. It covers topics such as cardiac output, cardiac index, stroke volume, preload, afterload, contractility, central venous pressure, pulmonary artery occlusion pressure, and systemic vascular resistance. The correct answers to common exam questions related to these fundamental cardiac hemodynamic principles, equipping nurses with the knowledge and understanding required to provide effective patient care in critical care settings. The detailed explanations and numerical values for the various parameters offer a valuable resource for nurses preparing for the ccrn (critical care registered nurse) or aacn (american association of critical-care nurses) certification exams, as well as for those seeking to enhance their clinical expertise in cardiac hemodynamics.

CCRN AACN Exam Questions With 100% Correct Answers 2023 cardiac output - Correct Answer-The volume of blood ejected from the left side of the heart in one minute. 4-8 L/min HR x SV Cardiac Index - Correct Answer-CO/BSA 2.5-4.3 Stroke Volume (SV) - Correct Answer-The amount of blood pumped out of the heart with each contraction. (Vol ejected with each beat) 60-100 Preload. Afterload Contractility Stoke Volume Index (SVI) - Correct Answer-35-60 Preload - Correct Answer-volume of blood in ventricles at end of diastole Pressure generated by vol of blood in ventricle at end of diastole RV: cvp right artery pressure/ RVEDVI LV: PAOP/ PAD/ LAP/ SVV-PPV-SPV CVP (central venous pressure) - Correct Answer-A direct measurement of the blood pressure in the right atrium and vena cava. CVP reflects the amount of blood returning to the heart and the ability of the heart to pump blood from the right heart into the pulmonary system. 0-5 Optimal -10 PAOP (wedge) - Correct Answer-6-12 Optimal 14-18 critical patient RVEDVI - Correct Answer-frank sterling curve dynamic pressure - Correct Answer-SVV/POV/SPV 10-15% Frank-Starling Law - Correct Answer-The greater the stretch, the stronger is the heart's contraction. This increased contractility results in an increased volume of blood ejected (Increased SV) Reducing preload - Correct Answer-Diuretics Vasodilator (think venous bed) Increasing preload - Correct Answer-Volume Vasoconstriction of venous bed Afterload - Correct Answer-the amount of resistance to ejection of blood from the ventricle RV: SVR LV: PVR The higher the greater the work Increases myocardial oxygen demand Decrease contractility RV more sensitive than LV SVR (systemic vascular resistance) - Correct Answer-Best indicator of left sided afterload Overall resistance to systolic ejection 80 x (MAP-RAP)/CO 800-1200. (Index. 1970-3900)
