Final answer:
Fresh frozen plasma has the highest citrate content among blood products, as it is composed of plasma, which contains citrate used as an anticoagulant.
Step-by-step explanation:
The question is about identifying which blood product has the highest citrate content. Citrate is used in blood product storage as an anticoagulant, and its concentration is highest in products with the most plasma volume, as plasma is where citrate is found. Based on the blood components, the blood products can be ranked in terms of plasma quantity, and therefore citrate content, from highest to lowest as follows: 1) Fresh frozen plasma 2) Platelets 3) Whole blood 4) Packed red blood cells. Therefore, fresh frozen plasma would have the highest citrate content as it is composed of essentially only plasma.
Fresh frozen plasma (FFP) is a blood product that is high in clotting factors, which are found in plasma, as well as other essential proteins, hormones, and antibodies. It is separated by centrifugation and frozen to preserve these factors.
