both systolic and diastolic BP elevated

Question 3

who gets 2x more HTN than whites

Answer 3

Non hispanic blacks, 5-18x ESRD increased risk

Question 4

MAP =

Answer 4

SVR x CO

Question 5

most patients with hypertension have

Answer 5

INCREASED SVR

Question 6

what changes do NO and endothelin undergo in hypertensive patients?

Answer 6

reduced NO activity maybe due to oxidative stress and AT2

Elevated levels of endothelin

Question 7

why do hypertensive patients fail to excrete more Na to lower BP?

Answer 7

less nephrons

- activated SNS and RAAS

Question 8

2 reasons why increased BP leads to more vasoconstriction

Answer 8

organ perfusion -

Na/K atpase inhibitor to get rid of salt but vasoconstricts

Question 9

in sustained hypertension what does increased SVR lead to

Answer 9

structural vessel changes -

hypertrophy and hyaline arteriosclerosis

Question 15

every 20/10 increase in BP after 115/75

Question 24

to prevent hypokalemia what can you do

Answer 24

combine a thiazide with a K+ sparing diuretic

what should you avoid adding to a beta blocker?

Answer 33

diltiazem or verapamil

Question 34

factors that reduce the NNT

Answer 34

- higher baseline cV risk - higher initial raised BP - longer duration of treatment - greater magnitude of BP drop - statin/aspirin
