3. Antibiotic first or blood first during transfusion? - ANSWER Both
at same time if they have separate lines.
4. What is the maximum time limit for completing a blood
transfusion? - ANSWER 4 hours maximum to prevent bacterial
contamination.
5. What vital signs must be taken before blood transfusion? -
ANSWER Temperature, pulse, respirations, blood pressure, and
oxygen saturation.
6. How often should vital signs be monitored during transfusion? -
ANSWER Every 15 minutes for first hour, then every 30 minutes.
7. What is the first sign of a transfusion reaction? - ANSWER Change
in vital signs, especially temperature elevation.
8. What should you do if a transfusion reaction is suspected? -
ANSWER Stop transfusion immediately, maintain IV access with
normal saline, notify physician.
Blood Types and Compatibility
,9. What blood type is the universal donor? - ANSWER Type O
negative (O-
).
10. What blood type is the universal recipient? - ANSWER Type AB
positive (AB+).
11. What temperature should blood products be stored at? - ANSWER
1-6°C (34-43°F) in blood bank refrigerator.
12. How long can blood be out of refrigeration before it must be
returned? - ANSWER 30 minutes maximum before transfusion
must begin.
13. Can type A blood receive type B blood? - ANSWER No,
incompatible and will cause hemolytic reaction.
14. What happens if incompatible blood is transfused? - ANSWER
Hemolytic reaction, hemolysis, kidney failure, shock, death.
15. What is type and screen? - ANSWER Determines patient's blood
type and screens for antibodies.
16. What does ABO incompatibility cause? - ANSWER Immediate
hemolytic transfusion reaction. Transfusion Reactions
17. What are signs of acute hemolytic reaction? - ANSWER Fever,
chills, back pain, chest pain, dyspnea, hypotension.
18. What is febrile non-hemolytic reaction? - ANSWER Fever and
chills without hemolysis, most common reaction.
19. What is the Rh factor? - ANSWER Protein on red blood cells;
positive if present, negative if absent.
20. Can Rh negative patient receive Rh positive blood? - ANSWER
No, will develop antibodies and future reactions.
21. What is crossmatching? - ANSWER Testing patient's blood with
donor blood to ensure compatibility.
, 22. How long is a crossmatch valid? - ANSWER 72 hours from time of
collection.
23. How do you treat febrile reaction? - ANSWER Stop transfusion,
give antipyretics, monitor vital signs.
24. What is allergic transfusion reaction? - ANSWER Urticaria,
itching, rash from plasma proteins.
25. What causes circulatory overload? - ANSWER Transfusing too
rapidly or too much volume.
26. Signs of circulatory overload? - ANSWER Dyspnea, crackles,
jugular vein distention, hypertension.
27. What is delayed hemolytic reaction? - ANSWER Occurs 3-10 days
posttransfusion, gradual hemolysis. Pre-Transfusion Procedures
28. What must be verified before starting transfusion? - ANSWER
Patient identity, blood type, crossmatch, expiration date.
29. Who must verify blood product information? - ANSWER Two
licensed nurses must double-check all information.
30. How do you treat mild allergic reaction? - ANSWER Give
antihistamines, may continue transfusion if mild.
31. What is anaphylactic reaction? - ANSWER Severe allergic reaction
with bronchospasm, shock, respiratory distress.
32. What is TRALI? - ANSWER Transfusion-Related Acute Lung
Injury causing pulmonary edema.
33. What patient identifiers are required? - ANSWER Full name, date
of birth, medical record number, blood bank number.
34. What IV gauge is needed for blood transfusion? - ANSWER 18-20
gauge catheter minimum for adequate flow.
