AFFP (apheresis fresh frozen plasma)
35
____ is plasma left over after production of cryoprecipitate
CRP (cryo-reduced plasma)
36
____ is derived from FFP and PF24 that has been thawed in a closed system
Thawed plasma
37

50
Why is Rh compatibility not important when choosing donor types for plasma product transfusions?
Does not contain RBcs or platelets
51
Process of issuing blood to nursing unit or surgery
- Transporter brings "pick-up slip" - Positive ID of recipient using two identifiers (name and MRN) - Dispense request sent to blood bank via computer - Blood product sent to unit via tube system - BB personnel review identifying info, inspect appearance of component, and ensure there's a system to maintain proper storage during transport
52
Appearance of bacterially contaminated unit
- Purplish color above buffy coat (or cell/anticoag layer) or air seen in bag
53
Proper labeling of unit
- Tie tag or label must include: name, identifying # of intended recipient; component unit #; interpretation of compatibility tests if performed - Expiration date
54
Corrective action if unit fails inspection
?
55
Process of returning blood when TX delays are encountered or if blood isn't used in surgery
Should be returned to blood bank for storage unless TX can be completed w/in 4 hours - Should not be left at RT ro stored in unmonitored fridge - Blood is viable only for 30 minutes if not issued in validated ice coolers
56
Most important step to ensure safe transfusions?
PATIENT IDENTIFICATION
57
Only acceptable additive solution to a unit of blood
Normal saline
58
Maximum time that a unit can be transferred to a patient
4 hours
59
Purpose of infusion sets
Retain blood clots and particles potentially harmful to recipient
60
Purpose of blood warmers
Needed if cold blood is infused very rapidly (or in trauma settings) to reduce risk of cardiac arrest
61
What patient population need blood warmers?
- Patients w/ cold agglutinins | - Infant exchange TX
62
Purpose of mechanical pumps
Deliver infusions at a controlled rate
63
What patient population need mechanical pumps?
Peds and neonates
64
Purpose of pressure devices
Infuse blood very rapidly most often in surgery
65
How is a patient monitored during a transfusion?
- Transfusionist should stay w/ patient for first 15 minutes (start w/ slow rate of 2mL/minute; severe rxns occur w/in first 25 mL) - Vital signs taken every 15 minutes; if all is good, increase rate to 4 mL/minute - Observe patient periodically throughout TX (~30 minutes) and up to 1 hour after transfusion
66
What should be done when a potential transfusion reaction is suspected?
STOP THE TRANSFUSION and call the doctor immediately
67
Which units are placed on the "Emergency Shelf" in most hospital blood banks?
2 units of O= and 2 units of O+
68
In an emergency situation, give ____ to females of child-bearing age or males younger than 13 years old
O neg
69
In an emergency situation, how is emergency blood released?
Physician must sign a release form
70
Why does a neonate require less than 7 day old RBCs?
Reduces risk of hyperkalemia and maximize 2,3-DPG
