5 Matching Questions

  1. Alpha adrenergic blockers
  2. high preload
  3. Preload
  4. Isoproterenol (Isuprel)
  5. SVR
  1. a vasodilation and vasoconstriction
  2. b amount of blood left in the right ventricle at the end of diastole
  3. c blocks the alpha receptors in arteries and veins// blocks vasoconstriction and is a vasodilator // Labetalol = peripheral alpha blocker and cardioselective beta blocker // Regitine
  4. d too much fluid = use vasodilators to correct
  5. e dosage is 1-7 mcg/min and has a beta 1 and a beta 2 effect

5 Multiple Choice Questions

  1. 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
  2. used for heart failure//increases contractility and vasodilates // loading dose is 0.75 mg/kg bolus // infusion 5-10 mcg/kg/min
  3. low dose is <2 mcg/min and the next dose is 2-16 mcg/min both doses have an alpha effect (vasoconstrict) used on patients with hyertension and patients with septic shock /// primary action increases SVR
  4. dosage is 10-100 mcg/min and has an alpha effect /// vasoconstricts/// used for hypertension, sepsis, and do NOT use if patient is hypovolemic
  5. Increase conduction/ heart rate / contractility/ stroke volume

5 True/False Questions

  1. Inotropic drugsenhance 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


  2. Nipridevasodilation and vasoconstriction


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


  4. Beta 2Peripheral arteriole vasodilation (involuntary muscles and skeletal // bronchodilation // decreases preload adn afterload // decreases SVR/BP, mVo2


  5. class i drugssodium channel blockers - slow down contractility - prolong the absolute refractory period
