5 Matching questions

  1. Moderate dose dopamine
  2. Hydralazine
  3. Preload
  4. Extremely high dose dopamine
  5. Phenylephrine (Neo-synephrine
  1. a dosage is 10-100 mcg/min and has an alpha effect /// vasoconstricts/// used for hypertension, sepsis, and do NOT use if patient is hypovolemic
  2. b potent arterial vasodilator// IV 5-10 mg q 4-8 hours // usually given between continuous infusion and oral dose of hypertensive meds
  3. c amount of blood left in the right ventricle at the end of diastole
  4. d 3-10 mcg/kg/min has a beta 1 effect (increases contractility and stroke volume) if CO is increased then that's just a bonus
  5. e > 20 also alpha but more potent

5 Multiple choice questions

  1. myocardium oxygen consumption
  2. 2-8 mcg/min has a beta 1 effect and increases contractility which increases cardiac output
  3. vasodilate the brain, heart, kidneys, and mesentery (different doses have different effects)
  4. venous vasodilator, increases coronary perfusion, decreases preload, comes in a glass bottle, 5 mcg/min and titrate/// WATCH blood pressure
  5. blocks the alpha receptors in arteries and veins// blocks vasoconstriction and is a vasodilator // Labetalol = peripheral alpha blocker and cardioselective beta blocker // Regitine

5 True/False questions

  1. high preloadtoo much fluid = use vasodilators to correct

          

  2. Class IAEncainide, Flecainide, Rythmol /// Most potent sodium channel blocker /// little effect on repolarization /// increases PR and QRS duration

          

  3. Norephinephrine (Levophed)low dose is <2 mcg/min and the next dose is 2-16 mcg/min both doses have an alpha effect (vasoconstrict) used on patients with hyertension and patients with septic shock /// primary action increases SVR

          

  4. High dose dopamine3-10 mcg/kg/min has a beta 1 effect (increases contractility and stroke volume) if CO is increased then that's just a bonus

          

  5. Unclassified antidysrhythmicssodium channel blockers - slow down contractility - prolong the absolute refractory period
