5 Matching questions

  1. Extremely high dose dopamine
  2. Hydralazine
  3. Phosphodiesterase inhibitors
  4. Preload
  5. Nitroglycerin
  1. a venous vasodilator, increases coronary perfusion, decreases preload, comes in a glass bottle, 5 mcg/min and titrate/// WATCH blood pressure
  2. b > 20 also alpha but more potent
  3. c positive inotropes, positive vasodilators, increases CO due to decreased afterload /// Amrinone (Inocor) and Milrinone (Primacor) decreases afterload
  4. d potent arterial vasodilator// IV 5-10 mg q 4-8 hours // usually given between continuous infusion and oral dose of hypertensive meds
  5. e amount of blood left in the right ventricle at the end of diastole

5 Multiple choice questions

  1. alter blood pressure by altering preload and afterload, alters distribution of blood in teh body
  2. dosage is 10-100 mcg/min and has an alpha effect /// vasoconstricts/// used for hypertension, sepsis, and do NOT use if patient is hypovolemic
  3. peripheral vasodilators, decrease PVR, Nipride, Nitroglycerin, and Hydralazine
  4. 11-20 mcg/kg/min has an alpha effect and vasoconstricts /// high doses increase SVR, increase BP, increase the workload of the heart
  5. Produce sympathomimetic response (stimulate the heart rate and blood pressure) Naturally occuring = dopamine, epinephrine, norepinephrine, and phenylephrine/// synthetic = dobutamine and isoproterenol

5 True/False questions

  1. Class IBLidocaine, Mexiletine, and Tocainide /// treats SVT /// moderate effect on sodium channels /// shortens action potential

          

  2. Alpha adrenergic blockersblocks the alpha receptors in arteries and veins// blocks vasoconstriction and is a vasodilator // Labetalol = peripheral alpha blocker and cardioselective beta blocker // Regitine

          

  3. Alphavasodilation and vasoconstriction

          

  4. SVRvasodilation and vasoconstriction

          

  5. Class II drugsCalcium channel blockers /// primarily in sinus, AV nodes and atrial tissue /// treatment for SVT /// Verapamil, and Cardizem /// they slow the heart rate and decrease irritability
