4. A&P: 25 pts This is the most muscular chamber of the heart because it must propel blood into systemic arterial circulation. The mitral and aortic valve help regulate blood flow to and from this chamber. A

5. Answer: A&P 25 pts What is the left ventricle?

6. A&P: 50 pts This characteristic is unique to cardiac cells because it allows them to spontaneously and repeatedly generate electrical impulses to maintain a steady heart rate. A

7. Answer: A&P 50 pts What is Automaticity?

8. A&P: 75 pts This is the “pacemaker of the heart” and automatically initiates electrical impulses at a rate of 60-100 beats per minute. A

9. Answer: A&P 75 pts What is the SA (sinoatrial) node?

10. A&P: 100 pts This is the resistance the ventricles must work against to eject blood. Medications that dilate blood vessels will help reduce this. A

11. Answer: A&P 100 pts What is Afterload?

12. A&P: 150 pts This is located on the left side of the chest at the 5th ICS and midclavicular line. If it is dislocated laterally, this may indicate hypertrophy of the heart. A

13. Answer: A&P 150 pts What is PMI (Point of Maximal Impulse)?

14. Data Collection: 25 pts These include smoking, HTN, obesity, hyperlipidemia, physical inactivity, stress and DM. They can be eliminated, modified and/or controlled to improve CV health. A

15. What are modifiable CV risk factors? Answer: Data Collection 25 pts

16. Data Collection: 50 pts This part of the cardiac cycle is characterized by closure of the pulmonic and aortic valves and opening of the tricuspid and mitral valves. It is during this phase that the coronary arteries are being perfused. A

17. Answer: Data Collection 50 pts What is diastole? (noted by S2 and DBP reading)

18. Data Collection: 75 pts These two lab studies are indicative of myocardial damage if elevated. A

19. Answer: Data Collection 75 pts What are CK-MB (>5%) and Troponin I (TNI >0.3%)?

20. Data Collection: 100 pts This diagnostic test uses ultrasound waves to produce images of the heart. It assesses heart size and shape, mobility of chambers and valves and effectiveness of contractility. This is especially useful with a diagnosis of MI or CHF. A

21. Answer: Data Collection 100 pts What is an echocardiogram?

22. Data Collection: 150 pts Assessment findings of peripheral edema, stasis dermatitis, warm/ruddy skin and irregular/shallow ulcers of the medial ankle are indicative of this process. It can be managed by leg elevation and use of TEDS / SCD’s. A

23. Answer: Data Collection 150 pts What is venous insufficiency?

24. CV Meds: 25 pts This is the most important drug to administer to a person who presents with chest pain, SOB or a pulse oximeter reading of <90% A

25. Answer: CV Meds 25 pts What is Oxygen?

26. CV Meds: 50 pts This medication is used to dilate coronary and peripheral arteries leading to increased blood flow and oxygen to the heart. It can be given PO, SL or IV. It commonly causes hypotension and headache. A

27. Answer: CV Meds 50 pts What is Nitroglycerin (NTG)?

28. CV Meds: 75 pts This is a cardiac glycoside that exhibits a positive ionotropic affect on the myocardium. Altered liver/renal function and /or hypokalemia can lead to toxic affects such as anorexia, N/V, visual disturbances, fatigue and bradycardia. A

29. What is digoxin (Lanoxin)? Answer: CV Meds 75 pts • Be sure apical pulse is greater than 60 beats/minute prior to giving this medication!

30. CV Meds: 100 pts These medications inhibit the production of a potent vasoconstrictor which leads to vasodilation and excretion of Na and H2O from the body. Their most common side effects include hypotension, cough and hyperkalemia. A

31. Answer: CV Meds 100 pts What are ACE inhibitors? (Captopril,Enalapril, Monopril, Lisinopril)

32. CV Meds: 150 pts These medications help decrease the workload of the heart by decreasing HR and contractility which, in turn, decreases BP. Unfortunately they are not selective so they can cause bronchospasms in the lungs. A

33. Answer: CV Meds 150 pts What are Betablockers? (Atenolol,Nadolol, Metoprolol)

34. CV Diseases: 25 pts This lifestyle habit has the most impact on the development of CV disease because it constricts blood vessels, decreases HDL’s and is directly associated with atherosclerosis. A

35. Answer: CV Diseases 25 pts What is smoking?

36. CV Diseases: 50 pts This disease affects 1 out of every 4 adults and is caused by an increase in CO and an increase in peripheral resistance. It is controlled by lifestyle modification and medications such as diuretics, betablockers and ACE inhibitors. If not controlled, can lead to decreased perfusion to target organs such as the heart, brain, kidneys and eyes. A

37. Answer: CV Diseases 50 pts What is Hypertension? (HTN or elevated BP >140/90 on 3 occasions)

38. CV Diseases: 75 pts Symptoms of this disease may include chest pressure radiating to the jaw and left arm, indigestion, SOB, diaphoresis, anxiety and duration >30 minutes (unrelieved by rest or SL NTG). It is confirmed by labs and EKG changes and is initially treated by “MONA.” A

39. Answer: CV Diseases 75 pts What is a MI? (Myocardial Infarction or heart attack)

40. CV Diseases: 100 pts This disease process is characterized by intermittent claudication, pale/cyanotic skin, weak or absent pulses, loss of hair, and small/deep painful ulcerations to the toes/feet. If not treated promptly, can lead to gangrene / amputation. A

41. Answer: CV Diseases 100 pts What is Peripheral Arterial Disease (PAD)?

42. CV Diseases: 150 pts This CV alteration is characterized by decreased myocardial contractility and cardiac output leading to decreased peripheral perfusion, pulmonary congestion and edema, SOB, tachycardia and weakness. A

43. Answer: CV Diseases 150 pts What is Left-sided heart failure?
