  1. Vasoactive medications
  2. SVR
  3. Phenylephrine (Neo-synephrine
  4. Direct smooth muscle relaxers
  5. Preload
  1. a alter blood pressure by altering preload and afterload, alters distribution of blood in teh body
  2. b 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. c peripheral vasodilators, decrease PVR, Nipride, Nitroglycerin, and Hydralazine
  4. d amount of blood left in the right ventricle at the end of diastole
  5. e vasodilation and vasoconstriction

5 Multiple Choice Questions

  1. Quinidine, Procainamide, Disopyramide /// Widens the QRS/QT interval /// depresses contractility
  2. used for heart failure//increases contractility and vasodilates // loading dose is 0.75 mg/kg bolus // infusion 5-10 mcg/kg/min
  3. treat with fluids or peripheral vasoconstrictors
  4. enhance myocardial contractility/// include cardiac glycosides (digoxin), sympathomimetics, and phosphodiesterase inhibitors /// controls ventricular rate/// give for atrial fib /// used to improve stroke volume they increase contractility; however, oxygen consumption goes up increasing the workload on the heart
  5. Adenosine /// slows conduction through AV node, causes transient AV block and is used to treat SVT /// Magnesium /// treatment for torsades de pointes

5 True/False Questions

  1. High dose dopamine11-20 mcg/kg/min has an alpha effect and vasoconstricts /// high doses increase SVR, increase BP, increase the workload of the heart

          

  2. Isoproterenol (Isuprel)amount of blood pumped out of the left ventricle per beat

          

  3. Sympathomimeticsstimulate adrenergic receptors (norepinephrine, dopamine/// they can be alpha adrenergics, beta 1 adrenergics, beta 2 adrenergics, and dopaminergic

          

  4. Class III drugsBeta adrenergic blockers /// Blocks stimulation of sympathetic nervous system /// slows AV conduction /// Treatment for SVT's, A fib, A flutter /// Esmolol, Metoprolol, Propranolol

          

  5. Class IBQuinidine, Procainamide, Disopyramide /// Widens the QRS/QT interval /// depresses contractility
