5 Matching questions

  1. low preload
  2. Phosphodiesterase inhibitors
  3. Extremely high dose dopamine
  4. Class IA
  5. Norephinephrine (Levophed)
  1. a > 20 also alpha but more potent
  2. b Quinidine, Procainamide, Disopyramide /// Widens the QRS/QT interval /// depresses contractility
  3. c treat with fluids or peripheral vasoconstrictors
  4. d positive inotropes, positive vasodilators, increases CO due to decreased afterload /// Amrinone (Inocor) and Milrinone (Primacor) decreases afterload
  5. e 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

5 Multiple choice questions

  1. 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
  2. vasodilators, decreases blood pressure, Inhibits conversion of angiotensin 1 to II // may cause hypotension esp in hypovolemic patients // Coptopril and Enalapril
  3. < 2 mcg/min (not weight related) has a beta 2 effect and vasodilates
  4. Lidocaine, Mexiletine, and Tocainide /// treats SVT /// moderate effect on sodium channels /// shortens action potential
  5. treatment of acute heart failure // decreases filling pressures, decreased vascular resistance, preload, afterload, workload/// IV bolus 2 mcg/kg // Continous infusion 0.01 mcg/kg/min /// Natricore

5 True/False questions

  1. Calcium channel blockersblocks the alpha receptors in arteries and veins// blocks vasoconstriction and is a vasodilator // Labetalol = peripheral alpha blocker and cardioselective beta blocker // Regitine

          

  2. ContractilityEfficiency and strength of contraction

          

  3. high preloadtreat with fluids or peripheral vasoconstrictors

          

  4. mVo2vasodilation and vasoconstriction

          

  5. NipridePeripheral 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)
