NURS2750 UNIT 2 EXAM QUESTIONS AND ANSWERS WITH COMPLETE SOLUTIONS VERIFIED LATEST UPDATE GRADED A++ Congestive Heart Failure (CHF) Heart cannot pump enough blood for needs. Cardiac Output (CO) Blood ejected by ventricle in 1 minute. Stroke Volume (SV) Volume of blood pumped out per contraction. Preload Blood delivered to heart by venous return. Afterload Force needed to eject blood from ventricles. Systolic Heart Failure Inability to contract effectively, causing backup. Diastolic Heart Failure Inability to relax, affecting heart filling. Left-Sided Heart Failure Blood backs up into lungs, causing congestion. Right-Sided Heart Failure Fluid retention in limbs and abdomen. Ejection Fraction Percentage of blood pumped out of ventricle. Fatigue Common symptom due to reduced blood supply. Dyspnea Shortness of breath from fluid in lungs. Edema Swelling due to fluid retention in tissues. Hepatomegaly Enlargement of liver due to congestion. Splenomegaly Enlargement of spleen due to congestion. Ascites Fluid accumulation in peritoneal cavity. Paroxysmal Nocturnal Dyspnea Shortness of breath during sleep. Compensatory Mechanisms Body's response to maintain cardiac output. Renin-Angiotensin-Aldosterone System (RAAS) Hormonal system regulating blood pressure and volume. Myocardial Hypertrophy Heart muscle thickening due to increased workload. Baroreceptors Sensors detecting changes in blood pressure. Sympathetic Stimulation Increases heart rate and force of contraction. Parasympathetic Stimulation Decreases heart rate through vagus nerve. Cardiac Control Center Located in medulla, regulates heart function.
