5 Matching questions

  1. Class III drugs
  2. mVo2
  3. Class IV drugs
  4. Phosphodiesterase inhibitors
  5. low preload
  1. a positive inotropes, positive vasodilators, increases CO due to decreased afterload /// Amrinone (Inocor) and Milrinone (Primacor) decreases afterload
  2. b 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
  3. c treat with fluids or peripheral vasoconstrictors
  4. d myocardium oxygen consumption
  5. e Calcium channel blockers /// primarily in sinus, AV nodes and atrial tissue /// treatment for SVT /// Verapamil, and Cardizem /// they slow the heart rate and decrease irritability

5 Multiple choice questions

  1. 2-8 mcg/min has a beta 1 effect and increases contractility which increases cardiac output
  2. Quinidine, Procainamide, Disopyramide /// Widens the QRS/QT interval /// depresses contractility
  3. Efficiency and strength of contraction
  4. peripheral vasodilators, decrease PVR, Nipride, Nitroglycerin, and Hydralazine
  5. venous vasodilator, increases coronary perfusion, decreases preload, comes in a glass bottle, 5 mcg/min and titrate/// WATCH blood pressure

5 True/False questions

  1. Beta 1Peripheral arteriole vasodilation (involuntary muscles and skeletal // bronchodilation // decreases preload adn afterload // decreases SVR/BP, mVo2


  2. Dobutamine (Dobutrex)vasodilate the brain, heart, kidneys, and mesentery (different doses have different effects)


  3. DA-1 receptor agonistpotent vasodilator, affects peripheral, renal and mesentary arteries, alternative to nipride // Clorazapam


  4. IV sedativePropofol (Diprivan) hypnotic used for induction and maintaince of anesthesia or sedation short half life typical dose is 5-50 mg/kg/min// the longer they are on it the longer it takes to wake them up// wean off of diprivan first before weaning off of the vent // doing sedation vacations 1 q shift helps decrease tolerance and nurse can perform neuro checks during this time


  5. Preloadamount of blood left in the right ventricle at the end of diastole
