5 Written questions

5 Matching questions

  1. Nursing interventions for shock
  2. 3 requirements for adequate blood flow
  3. distributive shock
  4. 3 organs most concerned about with shock
  5. Sequence of events for anaphylactic shock
  1. a monitor HR, BP, LOC, urine output. Recognize early and manage to reduce chance of end-stage organ damage. Provide pt teaching regarding drug therapy.
  2. b brain, heart, kidneys (cells with high metabolic rates
  3. c Adequate cardiac pump
    Effective vasculature
    Sufficient blood volume
  4. d MASSIVE VASODILATION resulting in relative hypovolemia (3 divisions: anaphylactic, neurogenic, septic)
  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. DECREASED: CO, stroke volume, UO, ventricular emptying, tissue perfusion, blood pressure, LOC.
    INCREASED: HR
  2. 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
  3. Extremes of age, Immunosuppression, Chronic illness, Malnutrition.
  4. Drug 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
  5. Stabilization of spinal cord injury, positioning spinal anesthetic patient properly, giving glucose for hypoglycemia.

5 True/False questions

  1. oncotic pressurethe 'pushing force', pushing the fluid out of the capillaries. It's the result of the actual pressure of the fluid on the capillary walls.

          

  2. neurogenic shockpump failure - 80-100% mortality rate

          

  3. what is the universal blood typeMASSIVE VASODILATION resulting in relative hypovolemia (3 divisions: anaphylactic, neurogenic, septic)

          

  4. Sequence of events for hypovolemic shockprevious 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. Causes of neurogenic shock?MI, arrhythmias, valvular disease, cardiac surgery, cardiomyopathy.
