Deck 17: Properties of the Vasculature

Question 1

A 22-year-old student has to have a physical examination to certify that he is able to participate in interscholastic athletics.During the cardiovascular examination,you report his heart rate as 60 beats/minute and his arterial blood pressure as 118/68 mm Hg.According to echocardiographic study,his end-diastolic volume is 150 mL and his end-systolic volume is 60 mL. His cardiac output is:

A)4.5 L/minute
B)5.0 L/minute
C)5.4 L/minute
D)5.9 L/minute
E)6.3 L/minute

Answer 1

C

Question 2

A 22-year-old student has to have a physical examination to certify that he is able to participate in interscholastic athletics.During the cardiovascular examination,you report his heart rate as 60 beats/minute and his arterial blood pressure as 118/68 mm Hg.According to echocardiographic study,his end-diastolic volume is 150 mL and his end-systolic volume is 60 mL. From the data,you estimate his pulse pressure to be:

A)50 mm Hg
B)60 mm Hg
C)68 mm Hg
D)80 mm Hg
E)90 mm Hg

Answer 2

A

Question 3

A 22-year-old student has to have a physical examination to certify that he is able to participate in interscholastic athletics.During the cardiovascular examination,you report his heart rate as 60 beats/minute and his arterial blood pressure as 118/68 mm Hg.According to echocardiographic study,his end-diastolic volume is 150 mL and his end-systolic volume is 60 mL. Starling forces are measured across a systemic capillary wall,and the following values are obtained:
If the reflection coefficient for protein ()across this capillary wall is 0.8,what is the net pressure and direction of fluid flow across the capillary wall?

Answer 3

C

Question 4

A 22-year-old student has to have a physical examination to certify that he is able to participate in interscholastic athletics.During the cardiovascular examination,you report his heart rate as 60 beats/minute and his arterial blood pressure as 118/68 mm Hg.According to echocardiographic study,his end-diastolic volume is 150 mL and his end-systolic volume is 60 mL. The patient's mean arterial pressure is estimated as:

A)68 mm Hg
B)77 mm Hg
C)85 mm Hg
D)92 mm Hg
E)118 mm Hg
