5 Matching questions

  1. Direct smooth muscle relaxers
  2. Class IV drugs
  3. Sympathomimetics
  4. Epinephrine (Adrenalin) medium dose
  5. SVR
  1. a Calcium channel blockers /// primarily in sinus, AV nodes and atrial tissue /// treatment for SVT /// Verapamil, and Cardizem /// they slow the heart rate and decrease irritability
  2. b 2-8 mcg/min has a beta 1 effect and increases contractility which increases cardiac output
  3. c peripheral vasodilators, decrease PVR, Nipride, Nitroglycerin, and Hydralazine
  4. d stimulate adrenergic receptors (norepinephrine, dopamine/// they can be alpha adrenergics, beta 1 adrenergics, beta 2 adrenergics, and dopaminergic
  5. e vasodilation and vasoconstriction

5 Multiple choice questions

  1. breaks down into cyanide, light sensitive, venous and arterial vasodilation, weight based, given to decrease blood pressure, decreases preload and afterload, .5 mcg/kg.min and titrate (avg. = 3mcg/kg/min) watch blood pressure!
  2. dosage is 1-7 mcg/min and has a beta 1 and a beta 2 effect
  3. sodium channel blockers - slow down contractility - prolong the absolute refractory period
  4. Slows repolarization (filling)/// Almiodarone (used for atrial and ventricular dysrhythmias), Dofetilide (Tikosyn) used for symptomatic afib/ flutter to NSR (in order to use have to be hospitalized and monitored IV only/// Ibutilide (Covert) used for afib/flutter to NSR
  5. 11-20 mcg/kg/min has an alpha effect and vasoconstricts /// high doses increase SVR, increase BP, increase the workload of the heart

5 True/False questions

  1. Stroke volumeamount of blood left in the right ventricle at the end of diastole

          

  2. mVo2myocardium oxygen consumption

          

  3. Class IAQuinidine, Procainamide, Disopyramide /// Widens the QRS/QT interval /// depresses contractility

          

  4. Epinephrine (Adrenalin) high dose< 2 mcg/min (not weight related) has a beta 2 effect and vasodilates

          

  5. Nitroglycerinbreaks down into cyanide, light sensitive, venous and arterial vasodilation, weight based, given to decrease blood pressure, decreases preload and afterload, .5 mcg/kg.min and titrate (avg. = 3mcg/kg/min) watch blood pressure!
