CEN Latest Study Guide with Correct Answers 2024 Cardiac Output Correct Answer: amount of blood ejected from the left ventricle each minute-normal cardiac output is 4-8 L per a minute Stroke Volume Correct Answer: The amount of blood ejected from the left ventricle with each contractions; normal is 50-100 mL/ contraction Preload Correct Answer: Amount of blood going into the heart. Right ventricle-assess JVD, Left ventricle- Assess lung sounds Afterload Correct Answer: The pressure...

Pam Bartley CEN Study Guide-Cardiology Verified A+ Cardiac output ️️stroke volume x heart rate (amount of blood ejected per contraction) Primary compensatory mechanism for low cardiac output in peds ️️Tachycardia Late sign of low CO ️️Hypotension, bradycardia is ominous sign in peds What is stroke volume influenced by ️️afterload, preload, contractility Preload ️️volume evaluated by CVP How to increase preload ️️volume (blood/fluids), pressprs How to decreas...

Cardiac output = - CO + HR x stroke volume (amount of blood ejected per contraction) Primary compensatory mechanism of low Cardiac output in peds? Other signs? - Tachycardia -- Peds are unable to increase stroke volume. Hypotension is a late sign, and bradycardia is an ominous sign in peds. Stroke Volume is influenced by... - Contractility, preload, and afterload. Frank-Starling's Law -- Stretch heart with volume to increase contractility (rubber band snapping shut) Preload is eval...

Mean Arterial Pressure correct answer average pressure over entire cardiac cycle, better indicator of perfusion compared to BP, maintain above 60 mm Hg (SBP+ [DBPx2])/3 Pediatric bolus correct answer 10 ml/kg narrowing pulse pressure correct answer low systemic pressure, r/t blood loss, decreased stroke volume widening pulse pressure correct answer high systemic pulse pressure, may be transient and normal after exercise, caused by chronic (arterial disease) and acute conditions (aortic...
