5 Matching questions

  1. SVR
  2. Class IB
  3. Phosphodiesterase inhibitors
  4. Norephinephrine (Levophed)
  5. Direct smooth muscle relaxers
  1. a peripheral vasodilators, decrease PVR, Nipride, Nitroglycerin, and Hydralazine
  2. b Lidocaine, Mexiletine, and Tocainide /// treats SVT /// moderate effect on sodium channels /// shortens action potential
  3. c vasodilation and vasoconstriction
  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. 11-20 mcg/kg/min has an alpha effect and vasoconstricts /// high doses increase SVR, increase BP, increase the workload of the heart
  2. > 20 also alpha but more potent
  3. arterial vasodilators // decreases blood pressure // both coronary and peripheral arteries /// used to treat hypertension, angina, antidysrhythmics (SVT's), watch for hypotension/// Procardia, Cardizem, Verapamil
  4. too much fluid = use vasodilators to correct
  5. vasodilate the brain, heart, kidneys, and mesentery (different doses have different effects)

5 True/False questions

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


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


  3. low preloadtoo much fluid = use vasodilators to correct


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


  5. Afterloadamount of pressure that the left ventricle has to pump against to get blood out of left ventricle
