  2. distributive shock
  3. Medical management of anaphylactic shock
  4. cardiogenic shock
  5. What is anaphylactic shock characterized by?
  1. a Vasodilation, Capillary permeability, Bronchospasm
  2. b MASSIVE VASODILATION resulting in relative hypovolemia (3 divisions: anaphylactic, neurogenic, septic)
  3. c Remove causitive agent.
    Order of TX:
    Epi IV to provide vasoconsrictive action and bronchodilation
    Diphenhydramine (Benadryl) IV to reverse histamine effectsa
    Nebulized albuterol (Proventil) to reverse histamine-induced bronchospasm.
    Oral steroid such as methylprednisolone (Solumedrol) for longer lasting antiinflammatory effects.
  4. d pump failure - 80-100% mortality rate
  5. e previous exposure to allergen with resulting antibody formation - exposure again to substance - develops a systemic antigen-antibody reaction - mast cells are provoked to release potent vasoactive substances, ie histamine or bradykinin - widespread vasoD and cap perm - Decreased venous return to heart - Decreased stroke volume - Decreased CO - Decreased BP - Decreased tissue perfusion - Respiratory arrest - Cardiac arrest - Death

5 Multiple Choice Questions

  1. Dilates vessels to enhance blood flow to the myocardium. Drug of choice for chest pain during MI.
  2. absolute volume loss or relative volume loss as with ascites (3rd spacing) - 10-31% mortality rate.
  3. to reverse low BP effect of nitroglycerin and morphine (MS) by elevating BP to perfuse vital organs. Causes peripheral vasoconstriction (alpha 1) and increases the force of contraction (beta 1 w/ IV fusion only). Potential to cause tachycardia.
  4. vasodilation d/t ALLERGIC REACTION causing release of HISTAMINE.
  5. Further increased HR; Further decreased BP; Increased pulse; decreased CO; cool, mottled skin; further increased respirations;
    decreased urine output; Decreased temperature/subnormal, low WBC count with many immature cells.

5 True/False Questions

  1. Body's compensatory mechanisms for shockmental confusion and oliguria


  2. Use of isoproterenol (Isuprel) in cardiogenic shokLimited to shock associated with slow HR and myocardial depression. Not a first line drug, used when pt not responsive to other meds.


  3. What is contraindicated in ventricular tachycardia with cardiogenic shockIABP


  4. Nursing considerations for septic shockvital signs, electrolyte imbalance, I&O, correct acidosis


  5. Nursing considerations during cardiogenic shockvital signs, electrolyte imbalance, I&O, correct acidosis
