Question 1

Which of the following statements most accurately describes the action of ACE inhibitors on the glomerular filtration pressure?

Answer 1

vasodilation of the efferent arteriole

Question 2

normal stroke volume range

Answer 2

55-100

Question 3

factors affecting stroke volume

Answer 3

Cardiac size
Contractility
Preload
Afterload

Question 4

how do you calculate stroke volume

Answer 4

It is calculated by subtracting the end systolic volume from the end diastolic volume.

Question 5

what integers with the absorption of ACEI reducing its therapeutic effect?
