ICU Prophecy – CV Exam Questions and Answers 100% Pass Asymptomatic bradycardia treatments - Correct Answer ️️ - What is cardiac tamponade? - Correct Answer ️️ -Fluid in the pericardial sac causing decreasing preload. This decreases SV and ultimately CO. Effects of Hyper/Hypokalemia and calcemia on EKG - Correct Answer ️️ -Hypokalemia causes U waves Hyperkalemia causes peaked T waves Normal BP? - Correct Answer ️️ -90-120/60-80 Normal HR? - Correct Answer ️️ -60-100 bpm Normal CO? - Correct Answer ️️ -4-8 L/min Normal SVR? - Correct Answer ️️ -800-1,200 dynes/seconds Normal PVR? - Correct Answer ️️ -37-250 dynes/sec/cm5 Normal SVo2? - Correct Answer ️️ -60-80% Normal PAP? - Correct Answer ️️ -Systolic: 15-30 mm Hg Diastolic: 4-12 mm Hg Normal CVP? - Correct Answer ️️ -2-6 mmHg V-fib in relation to CO - Correct Answer ️️ -V-fib produces an ineffective stroke, decreasing SV and CO. RV failure - treatment after RV MI - Correct Answer ️️ -Right sided measurements are more related to fluid balance and build up of fluid in the peripheral side. RV failure leads to insufficient LV preload. The result is low SV and CO. Treatment involves fluid loading with hypertonic fluids (3% saline, mannitol, 20% albumin) IABP optimal timing - Correct Answer ️️ -Inflation during diastole (AV closure) and deflation during systole (QRS) IABP functions - Correct Answer ️️ -Decrease afterload and increase coronary artery perfusion IABP waveforms - Correct Answer ️️ -Unassisted Systolic
