Lab Exams Questions

1. Calvin had a MAP of 80 mmHg and a diastolic BP of 70 mmHg.  Calculate his stroke volume.  Give your answer in mL/beat.

2.  Before exercising, Rebecca had the following:

HR = 80 b/min
BP = 100/60 mmHg

After exercising, she had the following:
HR = 120 b/min
BP = 110/50 mmHg

Calculate her % change in cardiac output.

3. Titus had a BP of 120/80 mmHg.  He was getting his BP checked on his left arm and the nurse pumped the sphygmomanometer up to 180 mmHg.  At this pressure the nurse attempted to feel his left radial pulse.  Will she be able to feel it?

4.  Calculate the atrial rate.

5. Marko had a cardiac output of 5 L/min, a heart rate of 100 beats/min, and a diastolic BP of 75 mmHg.  Calculate his systolic BP.

6.  Suppose a red blood cell traveled from the splenic vein all the way to the internal carotid artery.  How many capillary beds would it pass through?

7. Tom had a BP of 130/100 mmHg and a cardiac output of 3 L/min.  Calculate his stroke volume. Give your answer in milliliters/beat.

8. While exercising, Tom's systolic BP went up by 9 mmHg and his diastolic BP went down by 9 mmHg.  Thus his MAP must have __________________________________.

9. During aerobic exercise, cardiac output will ________________________.

10. Calculate the voltage amplitude of the T wave.
