5 Matching questions

  1. Alpha adrenergic blockers
  2. Contractility
  3. low preload
  4. Calcium channel blockers
  5. Class IC
  1. a blocks the alpha receptors in arteries and veins// blocks vasoconstriction and is a vasodilator // Labetalol = peripheral alpha blocker and cardioselective beta blocker // Regitine
  2. b arterial vasodilators // decreases blood pressure // both coronary and peripheral arteries /// used to treat hypertension, angina, antidysrhythmics (SVT's), watch for hypotension/// Procardia, Cardizem, Verapamil
  3. c Encainide, Flecainide, Rythmol /// Most potent sodium channel blocker /// little effect on repolarization /// increases PR and QRS duration
  4. d treat with fluids or peripheral vasoconstrictors
  5. e Efficiency and strength of contraction

5 Multiple choice questions

  1. dosage is 1-7 mcg/min and has a beta 1 and a beta 2 effect
  2. > 20 also alpha but more potent
  3. Peripheral 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)
  4. Peripheral arteriole vasodilation (involuntary muscles and skeletal // bronchodilation // decreases preload adn afterload // decreases SVR/BP, mVo2
  5. potent arterial vasodilator// IV 5-10 mg q 4-8 hours // usually given between continuous infusion and oral dose of hypertensive meds

5 True/False questions

  1. Direct smooth muscle relaxersperipheral vasodilators, decrease PVR, Nipride, Nitroglycerin, and Hydralazine

          

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

          

  3. Stroke volumeamount of blood left in the right ventricle at the end of diastole

          

  4. Phenylephrine (Neo-synephrinelow 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. Norephinephrine (Levophed)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
