Once thawed, Fresh Frozen Plasma must be transfused within:

Fresh Frozen Plasma (FFP) contains clotting factors and is typically stored at temperatures below -18°C. Once thawed, FFP is perishable and must be transfused within a specified time frame to ensure that it remains safe and effective. The correct timeframe for the transfusion of thawed FFP is 24 hours. This period is established to minimize the risk of bacterial growth and to ensure that the clotting factors remain functional.

Immediately after thawing, FFP should be used promptly to maximize its therapeutic benefits for patients needing coagulation support. If it is not transfused within the 24-hour period, the quality and safety of the plasma can deteriorate, making it less effective for treating conditions that require clotting factor replenishment.

The other options suggest shorter transfusion times, which do not align with current guidelines and practices regarding the safe administration of thawed FFP.
