5 Matching questions

  1. Why are hemorrhages widespread?
  2. Decompensated shock
  3. Pathology of shock
  4. Pumonary Infarct
  5. Anemic infarct
  1. a when early shock fails: hypotension occurs, BP and CO fall. Tachypnea and SOB lead to heart failure and pulmonary edema causing anoxia, lead to ARDS.
  2. b white; organs with single blood supply
  3. c (upon autopsy) interal organs are congested and wet from edema; the lungs are 2-3 times heavier. the liver is congested and blood oozes from it. the intestines are dark from blood pooling and wet. the kidneys are swollen, pale, and congested. and the brain is edematous, flattened gyri.
  4. d because of DIC
  5. e emobilzation to small distal vessels in lung may cause ischemic necrosis of tissue infarct

5 Multiple choice questions

  1. a sudden onset of fibrin thrombi in the microcirculation with consumption of coagulation factors and formation of fibrin degradation products. Potential complication with widespread of thrombin.
  2. ischemic necrosis of tissue distal to an area of arterial occulsion or in an area of obstructed venous outflow
  3. excess fluid in the interstital spaces of the body
  4. -20 to 25 per 100,000 PTs have it
    -fatal if 60% of circulation is obstructed
  5. early stages of shock are reversible and treatable. in the early stages, peripheral vasoconstriction helps compensate for hypoperfusion. the central pooling redirects blood to vital organs. if untreated, can cause death.

5 True/False questions

  1. Arterial Thrombi Morphologyadherent masses of blood that have areas of pale alternating with areas of red - lines of zahn


  2. Irreversible shockthe end result of decompensated shock. marked by: circulatory collapse, hypoperfusion of vital organs, and loss of vital functions. PTs are in distress and are frantic, DIC is common, and high mortality.


  3. Oliguriamixed acidosis occurs. result of renal, anaerobic glycolosis, and respiratory insufficiency.


  4. Embolisma detached solid, gaseous, or liquid mass that is carried by the blood from site of origin to a distal site. May lodge in pulmonary or systemic circulation.


  5. Red infarctwhite; organs with single blood supply
