  6. Coagulation is a ______-based process.
    Cell
  7. Where does coagulation occur? (3 places)
    • Occurs on the surface of endothelial
    • cells, subendothelial cells, and platelets
  8. Which coagulation factors are involved in the intrinsic pathway?
    8,9,11,12
  9. Which coagulation factors are involved in the extrinsic pathway?
    3, 7
  10. The "common coagulation pathway" occurs after activation of what factor?
    X
  11. Platelet count is actual number of
    __________ per cubic ___ of blood
    platelets (thrombocytes), mL
  12. What is normal platelet count?
    150,000-400,000/mm3
  13. _______________ is the term for a platelet count lower than 150,000.
    Thrombocytopenia
  14. _______________ is the term for a platelet count greater than 400,000.
    thrombocytosis
  15. ACT stands for what lab term?
    Activated Clotting Time
  16. a normal Activated Clotting Time
    70-180 sec
  17. Define Activated Clotting Time:
    Measures the amount of time required for
    ____  ____ to clot in a test tube
    Whole blood
  18. What is ACT used to measure in the OR?
    Heparin therapy
  19. With an ACT measurement, what situation would permit an acceptable time of 400 sec?
    cardiopulmonary bypass (CPB)
  20. Partial Thromboplastin Time, or PTT, measures what factors?
    INSTRINSIC (8,9,11,12)
  21. In a PTT, which factors, other than the intrinsic being measured, must be present in order to obtain normal lab values?
    1,2,5,10
  22. What is normal PTT?
    25-38 sec
  23. If PTT is used to monitor heparin, what is an acceptable value?
    1.5-3x normal values
  24. Prothrombin time (PT) measures what factors?
    VII, and common (I,II,V,X)
  25. What is a normal PT in sec?
    10-14 sec
  26. FACTOR ___ DEFICIENCY IS THE ONLY
    CAUSE OF A PROLONGED PT WITH A NORMAL PTT.
    VII
  27. What are the causes of prolonged PT (1.5-2x)
    • Low levels of VII, X, V,
    • LOW prothrombin,
    • LOW fibrinogen
  28. why was International Normalized Ratio (INR) developed?
    to normalize PT times, which often vary among labs
  29. INR is used to measure
    oral anticoagulation therapy
  30. Therapeutic warfarin dosing occurs
    when INR = _____?
    2.0-3.0
  31. What is a type and screen?
    Recipient’s blood has been typed for A, B, and Rh antigens and screened for common antibodies
  32. How long is a type and screen valid?
    72 hrs
  33. Define type and cross blood screen:
    • Recipient’s blood is incubated with the donor blood product
    • Clumping occurs if the cross-match is incompatible
  34. How long does a type and cross take?
    10 min plus 45 min
  35. what are the two parts of type and cross-match:
    PART 1: Recipient’s plasma is incubated with the donor RBCs (MAJOR)

    PART 2: Recipient’s RBCs are incubated with the donor plasma (MINOR)
  36. What type of PBRCs can be transfused to
    anyone (what is the universal donor)?
    O
  37. What is the universal donor of platelets,
    FFP, and cryoprecipiate,? WHY?
    Type AB platelets, cryo, or FFP

    because they contain neither anti-A nor anti-B antibodies
