5 Matching questions

  1. Hydralazine
  2. Epinephrine (Adrenalin) low dose
  3. Vasoactive medications
  4. Catecholamines
  5. high preload
  1. a alter blood pressure by altering preload and afterload, alters distribution of blood in teh body
  2. b Produce sympathomimetic response (stimulate the heart rate and blood pressure) Naturally occuring = dopamine, epinephrine, norepinephrine, and phenylephrine/// synthetic = dobutamine and isoproterenol
  3. c potent arterial vasodilator// IV 5-10 mg q 4-8 hours // usually given between continuous infusion and oral dose of hypertensive meds
  4. d < 2 mcg/min (not weight related) has a beta 2 effect and vasodilates
  5. e too much fluid = use vasodilators to correct

5 Multiple choice questions

  1. sodium channel blockers - slow down contractility - prolong the absolute refractory period
  2. < 3 mcg/kh/min has a dopaminergic effect (vasodilates) and is used to improve perfusion of the kidneys
  3. Lidocaine, Mexiletine, and Tocainide /// treats SVT /// moderate effect on sodium channels /// shortens action potential
  4. 2-8 mcg/min has a beta 1 effect and increases contractility which increases cardiac output
  5. amount of pressure that the left ventricle has to pump against to get blood out of left ventricle

5 True/False questions

  1. SVRmyocardium oxygen consumption

          

  2. Unclassified antidysrhythmicsSlows 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

          

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

          

  4. IV sedativepotent arterial vasodilator// IV 5-10 mg q 4-8 hours // usually given between continuous infusion and oral dose of hypertensive meds

          

  5. Isoproterenol (Isuprel)dosage is 1-7 mcg/min and has a beta 1 and a beta 2 effect
