Normal BP - ANSWER-SBP: <120
DBP: and <80
Prehypertension BP - ANSWER-SBP: 120-139
DBP: or 80-90
Stage I HTN BP - ANSWER-SBP: 140-150
DBP: or 90-99
Stage II HTN BP - ANSWER-SBP: >/= 160
DBP: or >/= 100
Characteristics of hypertensive urgency? - ANSWER-SBP: >/= 180
DBP: >/= 120
Absence of acute end organ damage
BP should be reduced over hours to days
Characteristics of hypertensive emergency? - ANSWER-Presence of acute end organ
damage and BP elevation
Organ damage is the result of acute rise in BP
BP should be reduced immediately to reduce further damage
Why do diuretics make BP go down? - ANSWER-Diuresis/decreased blood volume, but
patients become tolerant to diuretic effect within a couple weeks. However, BP stays
down even after diuretic effect wears off; we don't know why.
Why do ACE inhibitors make BP go down? - ANSWER-1) Renin converts
Angiotensinogen to Angiotensin I
2) ACE converts Angiotensin I to Angtiotensin II
*ACE inhibitors block the conversion of Angiotensin I into Angiotensin II
3) Angiotensin II attaches to Angiotensin receptors
4) Activation of receptors results in vasoconstriction, Na retention, and increased BP
*ACE inhibitors ultimately cause vasodilation and decreased serum sodium
Which direct vasodilator works on arteries, veins, and both? - ANSWER-Hydralazine =
arterial dilator; decreases afterload
Nitroglycerin = venous dilator; decreases preload
Nipride = arterial and venous dilator; equally reduces preload and afterload
How does nitroglycerin work for angina? - ANSWER-It decreases oxygen demand via a
reduction in preload and some beneficial redistribution of blood flow
