5 Matching questions

  1. Moderate dose dopamine
  2. Dopaminergics
  3. Contractility
  4. class i drugs
  5. Inotropic drugs
  1. a Efficiency and strength of contraction
  2. b 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
  3. c 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
  4. d sodium channel blockers - slow down contractility - prolong the absolute refractory period
  5. e vasodilate the brain, heart, kidneys, and mesentery (different doses have different effects)

5 Multiple choice questions

  1. amount of pressure that the left ventricle has to pump against to get blood out of left ventricle
  2. < 3 mcg/kh/min has a dopaminergic effect (vasodilates) and is used to improve perfusion of the kidneys
  3. < 2 mcg/min (not weight related) has a beta 2 effect and vasodilates
  4. myocardium oxygen consumption
  5. vasodilation and vasoconstriction

5 True/False questions

  1. AlphaPeripheral arteeriole vasoconstrictors// push fluid from the peripheral to the trunk // Increases preload and afterload /// Increases blood pressure/// Used in hypotensive patients /// increases mVo2 and decreases circulation to the extremities (fingers and toes)


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


  3. 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


  4. Stroke volumeamount of blood pumped out of the left ventricle per beat


  5. Epinephrine (Adrenalin) medium dosehas a alpha effect and vasoconstricts which increases mVo2 demands
