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


  1. How do diuretics lower bp? 
    • decrease Na and water
    • decrease blood volume
    • vasodilation
    • decrease bp
  2. What are the three groups of diuretics? 
    • 1. Thiazide
    • 2. Loop
    • 3. Potassium-Sparing
  3. Which drug is often used in combination with other antihypertensives for water retention? 
    Diuretics
  4. What is the most effective medication in the treatment of HTN and how do they work? 
    • Adrenergic Inhibiting Agents
    • modify function of sympathetic nervous system
  5. What are the different groups of Adrenergic Inhibiting Agents 
    • 1. Beta - (lol)
    • 2. Central - Catapress
    • 3. Peripheral - Resperine, Guan-
    • 4. Alpha - (osin)
  6. How do beta blocking adrenergic inhibitors lower BP? 
    • (-lol)
    • Inhibit renin secretion and typical beta response
    • decreases CO and BP
  7. How do centerally acting adrenergic inhibitors lower bp? 
    • Catapres -
    • suppresses norephrine and renin
    • decreases CO, BP, HR, SV and increases Na and water 

    leads to edema so a diuretic is combined with catapres
  8. What is Catapres-TTS? 
    peak? 
    • clonidine transdermal patch
    • peak 2-3 days
    • change wkly
    • rotate spots
  9. What are some possible side effects of Catapres? 
    • Retinal degeneration
    • Postural hypertension
    • PO-needs to be reduced after 2-3 days 
  10. What kind of antihyperlipidemic is Methyldopa?
    Centerally acting adrenergic inhibitor
  11. What are some side effects of methyldopa? 
    • thrombocytopenia and leukopenia
    • NEED TO MONITOR CBC
  12. What type of antihypertensive is Reserpine and how does it work? 
    • Peripherally acting adrenergic inhibitor
    • Blocks catecholamines, decreases norepinephrine, neuron impulses have no effect on vessels
    • -vasodilation, decrease in BP
    • -little to no effect on CO
  13. Reserpine is contraindicated in who? 
    depression, gallstones, epilepsy, arrhythmias, parkinsons, PUD
  14. What are some side effects of Reserpine?
    black stools, hemaemesis, nightmares, parkinson like syndrome, depression leading to suicide (months after stopped)

    *Orthostatic hypotension not usual
  15. Which antihypertensive should you administer with meals or milk?
    Reserpine
  16. Which drug should you not take with nasal decongestants? 
    Reserpine
  17. What are the different types of alpha adrenergic blocking agents? 
    • - osin
    • Prazosin- MINIPRESS
    • Tetrazosin
    • Doxazosin 
  18. How does minipress work to reduce bp? 
    • blocks alpha 1 receptors
    • - decrease PVR, BP -especially diastolic
    • -little to no effect on CO (unless pt has CHF may increase CO)
    • -reduces preload and afterload
  19. What is "first-dose hypotensive reaction"? 
    Which drug may cause this effect and how can you prevent it?
    • May occur .5-1.5 hours after initial dose or rapid increase- may cause lightheadedness, dizziness, syncope. 
    • Minipress and Doxazosin (effect is less in dox)
    • Administer first dose at bedtime to minimize and increase dosage slowly
  20. Which drug is a dual action alpha and beta blocker? 
    • Carvedilol (Coreg)
    • used in ED
    • PO only
    • Use: HTN and HF
  21. What type of drug is Captopril? 
    1st - ACE inhibitor (pril)
  22. What are the side effects of captopril? 
    • agranulocytosis, neutropenia, proteinuria, loss of taste - does return, increased BUN and K 
    • Patient should avoid emotional encounters and stress
  23. What type of drug is Losartan (Cozaar) and how does it work? 
    • Angeotensin II Reductase Inhibitor
    • blocks effects of angiotensin II causing vasodilation
    • -decreases bp, na & water, and blood volume
  24. Which drug has an adverse effect of upper respiratory infection and dyspepsia? 
    Losartan- Cozaar 
  25. Aliskiren (Tekturna) is what type of drug? 
    Oral renin inhibitor
  26. Which drug is less effective on African Americans? 
    Oral renin inhibitor-aliskiren (tekturna)
  27. Amoldipine (Norvasc) and Cardene IV are which type of antihypertensive? 
    Calcium channel blockers
  28. Diazoxide (Hyperstat) is which type of antihypertensive?
    • Arteriolar Vasodilator
    • relaxes smooth muscle - decrease PVR- does not effect venous vessels- reflexive increase in CO and HR(due to decreased BP) will maintain corornary and cerebral blood flow
  29. When in Diazoxide (hyperstat) used? 
    • rapid reduction in hypertensive emergencies
    • IV only
  30. Clients with intolerance to thiazide diuretics may not tolerate which drug? 
    Diazoxide (Hyperstat)
  31. Which drug requires you to lie down during therapy and 30 minutes after administration? 
    Diazoxide- hyperstat
  32. Which drug should be administered in less than 30 seconds and why? 
    • Diazoxide- hyperstat
    • because slower admin will result in decreased duration of effect

    *Admin as fast as you can! 
  33. Which type of drug is hydralazine (apresoline) and how does it work? 
    • arteriolar vasodilator
    • relaxes smooth muscle, decrease bp -diastolic more, reflex increase in co & hr. 
    • increase in renin= increases Na and water 
  34. SLE-like syndrome is a side effect of which drug? 
    arterial vasodilator-- hydralazine -Apresoline
  35. Which drug treats male pattern baldness when used topically? 
    arteriolar vasodilator- Minoxidil (Loniten) 
  36. Which drug has an adverse reaction of thiocyanate and cyanide toxicity? 
    arterial and venous dilator drug- Nitroprusside (Nipride)
