S&P Part 4

Question 1

Increase in stroke volume and decrease in HR:
Cardiac output and mean arterial pressure is _________
Pulse pressure is ________

Answer 1

Unchanged
Increased

Question 2

A well trained athlete has an ________ stroke volume and _______ heart rate = arterial palpation of an athlete at rest is typically strong, slow pulse

Answer 2

Increased
Decreased

Question 3

Decrease in arterial compliance:
Aortic systolic pressure _________
Aortic diastolic pressure __________
Mean arterial pressure _________

Answer 3

Increases
Decreases
Unchanged

Question 4

During a decrease in arterial compliance, ventricular _________ is sometimes triggered

Answer 4

Hypertrophy

Question 5

-Stiff arteries typically retain their large diameters, and resistance of these big vessels remain low
-Arterioles remain normal
Above means that the TPR does ____ change during decrease in arterial pressure

Answer 5

Not

Question 6

PDA:
A patient has a large left ventricular stroke volume = ________ aortic systolic pressure

Answer 6

Elevates

Question 7

PDA:
Between cardiac ejections, blood runs out of the aorta by 2 pathways:
Into the synthetic circuit and the open ductus
So aortic diastolic pressure __________ and aortic pulse pressure dramatically __________

Answer 7

Decreases
Increases

Question 8

A blood vessel with low compliance = can hold ____ blood than a blood vessel with high compliance with the _____ distending pressure

Answer 8

Less
Same
