Which blood product requires ABO compatibility and can be used for up to 5 days after thawing?

The choice of Fresh Frozen Plasma (FFP) is correct because this blood product indeed requires ABO compatibility for transfusion to ensure the recipient’s immune system does not react adversely to the transfused plasma. Mismatches in blood type can lead to serious complications including hemolytic reactions.

Furthermore, Fresh Frozen Plasma can be stored after thawing for a maximum of 5 days at refrigerator temperatures while still maintaining its effectiveness in providing clotting factors. This is critical in emergency settings where time-sensitive transfusions may be needed to manage coagulopathies or to stabilize patients in trauma situations.

The other options either do not require ABO compatibility or do not fit the criteria of being a blood product that can be used after thawing within the specified timeframe. For instance, Liquid Plasma is not typically used in the same manner as FFP, and Freeze Dried Plasma has different storage and compatibility requirements. Recombinant Factor VIIa is a clotting factor that functions differently and does not involve the same compatibility concerns as whole blood products. Each of these distinctions is important in clinical practice.
