5 Written questions

5 Matching questions

  1. High dose dopamine
  2. Amrinone (Inocor)
  3. Hydralazine
  4. Class II drugs
  5. Contractility
  1. a used for heart failure//increases contractility and vasodilates // loading dose is 0.75 mg/kg bolus // infusion 5-10 mcg/kg/min
  2. b Beta adrenergic blockers /// Blocks stimulation of sympathetic nervous system /// slows AV conduction /// Treatment for SVT's, A fib, A flutter /// Esmolol, Metoprolol, Propranolol
  3. c 11-20 mcg/kg/min has an alpha effect and vasoconstricts /// high doses increase SVR, increase BP, increase the workload of the heart
  4. d Efficiency and strength of contraction
  5. e potent arterial vasodilator// IV 5-10 mg q 4-8 hours // usually given between continuous infusion and oral dose of hypertensive meds

5 Multiple choice questions

  1. Quinidine, Procainamide, Disopyramide /// Widens the QRS/QT interval /// depresses contractility
  2. beta 1 effect with all doses which increases contractility /// Do NOT give for blood pressure /// decreases contractility /// used in patients with decreased CO and end stage heart disease /// it IS weight based /// low dose < 5, medium dose 5-20, high dose > 20
  3. dosage is 10-100 mcg/min and has an alpha effect /// vasoconstricts/// used for hypertension, sepsis, and do NOT use if patient is hypovolemic
  4. vasodilate the brain, heart, kidneys, and mesentery (different doses have different effects)
  5. amount of pressure that the left ventricle has to pump against to get blood out of left ventricle

5 True/False questions

  1. Sympathomimeticsvasodilate the brain, heart, kidneys, and mesentery (different doses have different effects)

          

  2. Inotropic drugssodium channel blockers - slow down contractility - prolong the absolute refractory period

          

  3. Moderate 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

          

  4. Class III drugsSlows 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. Unclassified antidysrhythmicsAdenosine /// slows conduction through AV node, causes transient AV block and is used to treat SVT /// Magnesium /// treatment for torsades de pointes
