NCLEX Heart Failure with correct answers 100% 2026

NCLEX Heart Failure with correct answers 100% 2026 What is heart failure? - Correct Answer condition when the heart becomes damaged or weakened by disease. The myocardium cannot pump effectively to meet metabolic needs Left ventricle (first, usually) isn't strong enough to accommodate the flow of blood back from the lungs to the heart Heart may not be able to relax properly to accommodate the flow of blood back from the lungs to the heart. Causes fluid to back up in lungs and other parts of the body What does ventricular function depend on? - Correct Answer Preload, afterload, contractility, heart rate. Two types of HF - Correct Answer acute and chronic Two types of systolic dysfunction - Correct Answer left and right What happens in systolic dysfunction? - Correct Answer enlarged ventricles fill with blood and end up pumping less than 40 to 50 (compared to 60) percent What happens in diastolic dysfunction? - Correct Answer Stiff ventricles fill with less blood than usual. Those ventricles pump out about 60 percent, but the amount may be lower than normal. What happens in LEFT systolic dysfunction? Volume, contractility, ventricle status, pumping force... - Correct Answer Volume overload and decreased contractility. Left ventricle can no longer pump normally. Heart can't pump with enough force for proper circulation. What are causes of LEFT SYSTOLIC dysfunction? Diseases, structural changes, effects on the muscle of the heart and the O2 of the body - Correct Answer CAD and hypertension. Structural changes lead to deteriorated cardiac function. Symptoms of low cardiac output and congestion. Effects the myocardium - volume overload or cardiac injury. Heart is unable to meet the body's metabolic requirements. Where does blood pool in left sided heart failure? - Correct Answer The ventricle, atrium and ultimately the PULMONARY veins.
