NR 507 - UNIT 3 FINAL EXAM QUESTIONS WITH CORRECT VERIFIED ANSWERS | 100% PASS (A+ CERTIFIED) 1. coronary artery disease Correct Answer caused by atherosclerosis and affects the heart by obstructing the supply of oxygenated blood, altering myocardial cell metabolism and nutrient uptake 2. coronary arteries Correct Answer blood vessels that supply the heart with blood to pump through the circulatory system 3. atherosclerotic conditions may affect Correct Answer preload - afterload - contractility - stroke volume - cardiac output 4. Preload Correct Answer stretching of the cardiac muscle cells before contraction 2 / 13 5. Afterload Correct Answer force against the heart or "load" the heart must pump against 6. Contractility Correct Answer strength of the heart muscle to contract 7. Stroke Volume (SV) Correct Answer volume of blood ejected during systole 8. Cardiac output Correct Answer heart rate x stroke volume 9. hyperlipidemia Correct Answer contributes to plaque formation and the risk of developing coronary artery disease 10. Lipids Correct Answer types of fat that travels through the bloodstream and includes cholesterol and triglycerides 11. Hyperlipidemia 3 / 13 Correct Answer lipid concentration in bloodstream is higher than normal 12. Cholesterol Correct Answer fatty substance produced by the liver that travels through the bloodstream 13. Triglycerides Correct Answer main type of lipids in the blood that provides energy to the body 14. Clinical manifestations of coronary artery disease Correct Answer indigestion - shortness of breath - heart palpitations - fatigue - diaphoresis - chest pressure, pain, tightness - epigastric, neck, shoulder, back, arm pain - lightheadedness/dizziness - nausea 15. Ways to diagnose coronary artery disease Correct Answer electrocardiogram (ECG) - echocardiogram 4 / 13 - exercise stress test - cardiac catheterization - coronary angiogram - coronary artery calcium scan 16. Lab tests for coronary artery disease Correct Answer metabolic panels - CBC - clotting factors - troponin T - C-reactive protein - serum lipid levels 17. First line of treatment for coronary artery disease Correct Answer "statins"; especially atorvastatin & rosuvastatin 18. High-density lipoprotein (HDL) Correct Answer "good" lipoprotein that works to rid the body of cholesterol through catabolism and excretion from the liver 19. Low-density lipoprotein (LDL) Correct Answer "bad" lipoprotein that promotes atheroma formation 20. Heart Disease 5 / 13 Correct Answer complex disease that results from any structural or functional impairment of ventricular filling or ejection of blood; the heart cannot generate adequate cardiac output, leading to inadequate oxygenation, ventilation, and perfusion 21. Left-sided heart failure Correct Answer occurs when the left ventricle walls of the heart become weak and thin and are unable to adequately pump blood to the body, leading to increased pressure in the left atrium and pulmonary veins 22. Causes of left-sided heart failure Correct Answer pulmonary vascular congestion - inadequate systemic perfusion 23. 3 types of left-sided heart failure Correct Answer left-sided heart failure with a reduced ejection fraction (HFrEF) - left-sided heart failure with a preserved ejection fraction (HFpEF) - mid-range ejection fraction (HFmrEF) 24. Left-sided heart failure with a reduced ejection fraction (HFrEF) is also called- : systolic heart failure
