    • Stage 2: 160/100
  2. Damage by sustained Hypertension
    • Heart- works harder=heart failure
    • Brain- damages vessels carrying blood and oxygen in brain can lead to TIA and CVA
    • Renal Function- vascular damage in arteries of kidneys lead to progressive loss of function
    • Eyes- vessels in retina can rupture or become occluded leding to visual impairment or blindness
  3. What lab results are most important for Diuretics and Digoxin?
  4. What should Asthma patients NOT take?
  5. What can happen when an ER patient comes in with really high BP and is given a vasodilator to lower it?
    BP can rise due to autoresponse
  6. Cardia Output x Systemic vascular resistance=
    Blood Pressure
  7. What can Beta Blockers do to heart rate?
    lower it
  8. What is the correlation between chronic hypertension and heartfailure?
    When the BP is always high, the heart works harder and gives out
  9. Triglycerides
