The flashcards below were created by user britsands on FreezingBlue Flashcards. What would you like to do?


  1. What caused preload to be increased
    • Hypervolemia
    • Regurgitation of the valves
  2. What increases afterload
    • Vasoconstriction
    • increase afterload= increase workload
  3. The five factors of Blood Pressure
    • Cardiac
    • sympathatic nervous system
    • Local regulation
    • renal fluid volume control
    • humoral
  4. Renin angiotensin aldosterone cycle?
    increased aldosterone---->
    • increased sodium retention
    • increased water reabosorption
    • increased blood volume
    • increased cardiac output
  5. Prehypertension:
    120-139/80-89
  6. hypertension stage 1
    140-159/90-99
  7. Hypertension stage 2
    Greater than or equal to 160/100
  8. MAP equation
    • (2)diastolyic + systolic
    • 3
  9. Primary hypertension happens in what percentage of people
    Secondary?
    • 90-95%
    • 5-10%
  10. Secondary hypertension is high in what?
    Childern
  11. Secondary Hypertension
    what is it?
    Causes of it?
    • Elevated BP with a specific cause
    • coarctation of aorta
    • renal disease
    • endocrine disorders
    • neurologic disorders
    • cirrhosis
    • sleep apnea
  12. Hypertension target organ damage
    Heart-
    • Coronary artery disease
    • left ventricular hypertrophy
    • heart failure
  13. Hypertension target organ damage
    Cerbrovascular disease
    • Stroke!
    • retinal damage (should get checked every 6 months
  14. Hypertension target organ damage
    kidney
    • nephrosclerosis
    • renal failure
  15. Diagnostic tests for hypertension
    • urinalysis, creatinine clearance
    • serum electrolytes, glucose
    • BUN and serum creatinine
    • Serum lipid profile (ldl, hdl, total cholersterol)
    • ecg
    • echocardiogram
  16. Drugs currentlly available fro treating hypertension work by either what 2 ways
    • 1) decreasing the volume of circulating blood and/or
    • 2) reducing SVR
  17. Weightloss of 10kg may decrease systolic by aprox what amount?
    5-20
  18. What should you monitor for whith drug side effects?
    • orthostatic hypotension
    • sexual dysfunction
    • dry mouth
    • frequent urination
    • coughing
    • high or low potassium
  19. What dietary teaching should you educate
    • less that 2.4 g of Na+
    • greater values of potassium , calcium, vit D, and omega 3-fatty acids
  20. What should you teach patients about how to track their hypertension?
    • have them keep a log
    • check twice a day, in the morning and before bed
    • teach what to watch for (swelling, headache)
  21. When is a second drug added to reginmen
    • thiazide diuretics 1st step
    • bp is more than 20/10 mm Hg above SBP and DBP goals, a second drug is added
  22. What is the diastolic have to be abruptly for hypertension crisis
    >140
  23. what is the most effective drug for hypertension crisis
    sodium mitroprusside
  24. Hydrochlorothiazide
    Thiazide diuretic
  25. Bumetanide (bumex)
    Furosemide (lasix)
    Loop diuretic
  26. Aldactone
    • Aldosterone receptor blockers
    • Potassium sparing diuretic
  27. Clonidine (Catapres)
    • Central-acting adrenergic antagonists
    • (reduces peripheral sympathetic tone, produces vasodialation, decreases svr and bp)
  28. Doxazosin (cardura)
    Prazosin (Minipress)
    • A1- adrenergic blockers
    • produces peripheral vasodialation (decreases svr and bp)
  29. Hydralazine (apresoline)
    • direct vasodialtors
    • reduces SVR and BP by direct arterial vasodialation for crisis hypertension
  30. amlodipine (norvasc)
    nifedipine (procardia)
    verapamil
    • Ca+ channel blocker
    • vasodialation and decreased HR
    • use cautiously in patients with heart failure or 2nd or 3rd heart block
    • avoid grapefruit
