PBSC SEM2 Test 6

  1. circulatory shock state resulting from severe allergic reaction producing an overwhelming systemic vasodilation and relative hypovolemia
    anaphylactic shock
  2. messenger substances that may be released by a cell to create an action at a site or be carried by bloodstream to a distant site before being activated; also called cytokines
    biochemical mediators
  3. shock state resulting from impairment or failure of the myocardium
    cardiogenic shock
  4. intravenous solutions that contain molecules that are too large to pass thru capillary membranes
  5. electrolyte solutions that move freely btw the intravascular compartment and interstitual spaces
  6. shock state resulting from displacement of blood volume creating a relative hypovolemia and inadequate delivery of oxygen to the cells; also called distributive shock
    circulatory shock
  7. shock state resulting from decreased intravascular volume due to fluid loss
    hypovolemic shock
  8. shock state resulting from loss of sympathetic tone causing relative hypovolemia
    nuerogenic shock
  9. circulatory shock state resulting from overwhelming infection causing relative hypovolemia
    septic shock
  10. overwhelming inflammatory response in absence of infection causing relative hypovolemiaand decreased tissue perfussion
    systemic inflammatory response syndrome (SIRS)
  11. What are the three stages of shock
    compensatory, progressive and irreversible
  12. In the compensatory stage of shock what are the clinical findings for BP, HR, Resprations, Skin, urinary output, LOC, and acid base balance
    Normal BP, >100 BPM, >20 RR, cold & clammy skin, decreased output, confusion, resp. alkalosis
  13. In the Progressive stage of shock what are the clinical findings for BP, HR, Resp. status, skin, urinary output, LOC, acid-base balance
    Systolic <80-90, >150BPM, rapid shallow resp. & crackles, mottled & petechaie skin, output = 0.5ml/kg/h, lethargy, metabolic acidosis
  14. In the irreversible stage of shock what are the clinical findings for BP, HR, Resp. status, skin, urinary output, LOC, acid-base blance
    BP requires mechanical or pharm. support, HR is erratic or asystole, requires intubation for breathing, skin is jaundice, anuric requires dialysis, unconcious, profound acidosis
  15. what are sympathomimetics used for in shock?
    improve contractility, increase stroke volume, increase cardiac output
  16. what are vasodilators used for in shock?
    reduce preload and afterload, reduce oxygen demand of heart
  17. what are vasoconstrictors used for in shock?
    increase blood pressure by vasoconstriction
  18. What are some external risk factors for hypovolemic shock?
    trauma, surgery, vomiting diarrhea, diuresis, diabetes insipidus
  19. what are some internal risk factors for hypovolemic shock?
    hemorrhage, burns, ascites, peritonitis, dehydration
  20. what is the proper positioning for a patient in shock?
    modified trendelenburg (lower extremities elevated 20 degrees, knees straight, trunk is horizontal and head is slightly elevated)
  21. what is the first line of treatment for cardiogenic shock?
    • supplemental oxygen
    • controlling chest pain
    • providing selected fluid support
    • admin. vasoactive meds
    • controlling HR w/ meds or by transthoracic or IV pacemaker
    • mechanical cardiac support if needed
