5 Matching questions

  1. Cause of anaphylactic shock?
  2. Nursing interventions for shock
  3. Body's compensatory mechanisms for shock
  4. What is cardiogenic shock characterized by?
  5. Causes of neurogenic shock?
  1. a DECREASED: CO, stroke volume, UO, ventricular emptying, tissue perfusion, blood pressure, LOC.
  2. b Severe allergic reaction in a patient who has previously been exposed to an allergen. Ie. contrast dyes, drugs, insect bites, foods such as peanuts.
  3. c monitor HR, BP, LOC, urine output. Recognize early and manage to reduce chance of end-stage organ damage. Provide pt teaching regarding drug therapy.
  4. d Increased HR, vasoconstriction, activates renin angiotensin mechanisms, ADH increases, increase secretion of epinephrine and norepinephrine to increase BP and HR.
  5. e Spinal cord injury, Spinal anesthesia, depressant action of medications, lack of glucose (insulin reaction or shock), Severe pain.

5 Multiple choice questions

  1. O-negative
  2. O2, control chest pain, selective fluid support, medications (dopamine, dobutamine, isoproterenol, norepinephrine, IV nitro)
  3. Adequate cardiac pump
    Effective vasculature
    Sufficient blood volume
  4. Id and treat infection (usually Gram neg); eliminate potential sources of infection (remove and culture all lines and tubes, restart lines at different sites); Start broad spectrum abx-usually 3rd generation cephalosporin and an aminoglycoside, until C&S reports are received. Change abx according to organisms to a more specific/less toxic abx.; fluid replacement; aggressive nutritional support
  5. intra-aortic ballon pump (IABP)

5 True/False questions

  1. septic shockvasodilation d/t mediators of inflammatory process in response to overwhelming INFECTION - 40-70% mortality rate depending on organism.


  2. Use of isoproterenol (Isuprel) in cardiogenic shokDrug of choice for cardiogenic shock because does not cause vasoconstriction but increases strength of contractions, improves stroke volume and CO. Minimal increase in HR. has a half-life of 2 minutes, given as an IV infusion drip, dosed in mcg/kg/min. only give in the ICU


  3. hypovolemic shockpump failure - 80-100% mortality rate


  4. What is anaphylactic shock characterized by?vasodilation (lowers BP) and increased capillary permeability/leakage d/t cellular injury from bacterial toxins- lose fluid out of vasculature.


  5. anaphylactic shockvasodilation d/t ALLERGIC REACTION causing release of HISTAMINE.
