40. 40[blank_start]Cardiac output[blank_end] is the product of two variables, stroke volume and heart beat. [blank_start]Heartbeat[blank_end] is simply a count of the number of times a heart beats per minute. [blank_start]Stroke volume[blank_end] is the amount of blood circulated by the heart with each beat. The formula for this is expressed as CO = SV x HR.

    1. ACardiac output
    2. BHeartbeat
    3. CStroke volume
41. 41Freshly oxygenated blood is first received by the:

    1. Aright ventricle
    2. Bleft ventricle
    3. Cright atrium
    4. Dleft atrium
42. 42Which of the following depolarizes next after the AV node?

    1. Aatrial myocardium
    2. Bventricular myocardium
    3. Cbundle branches
    4. DAV bundle
43. 43During atrial systole:

    1. Athe atrial pressure exceeds ventricular pressure
    2. B70 percent of ventricular filling occurs
    3. Cthe AV valves are open
    4. Dvalves prevent backflow into the great veins
44. 44Atrial repolarization coincides in time with the:

    1. AP wave
    2. BT wave
    3. CQRS wave
    4. DP-Q interval
45. 45Soon after the onset of ventricular systole the:

    1. AAV valves close
    2. Bsemilunar valves close
    3. Cthe first heart sound is heard
    4. Daortic pressure increases
46. 46The base of the heart is its ____________________ surface.

    1. Adiaphragmatic
    2. Bposterior
    3. Canterior
    4. Dinferior
47. 47In comparing a parallel artery and vein, you would find that:

    1. Athe artery wall is thicker
    2. Bthe artery diameter is greater
    3. Cthe artery lumen is smaller
    4. Dthe artery endothelium is thicker
48. 48Which layer of the artery wall thickens most in atherosclerosis

    1. Atunica media
    2. Btunica interna
    3. Ctunica adventitia
    4. Dtunica externa
49. 49Which of the following is NOT associated with aging?

    1. Aincreasing blood pressure
    2. Bweakening of venous valves
    3. Carteriosclerosis
    4. Dstenosis of the ductus arteriosis
50. 50Label the following diagram pertaining to normal and abnormal heart sounds

    

    1. Anormal
    2. Baortic stenosis
    3. Cmitral regurgitation
    4. Daortic regurgitation
    5. Emitral stenosis
