What is the name of the frozen factor VIII given to hemophiliacs?

Cryoprecipitate is the correct answer because it is a component of blood plasma that is rich in clotting factors, particularly factor VIII, fibrinogen, and von Willebrand factor. It is created by freezing and then thawing fresh frozen plasma (FFP), which allows the cryoprecipitate to precipitate out before being collected. This makes it an essential treatment for hemophiliacs who are deficient in factor VIII, as it provides them with the necessary factors to help promote blood coagulation and prevent excessive bleeding.

Other options are related to blood coagulation but serve different purposes. Prothrombin complex refers to a mixture of clotting factors, including factors II, VII, IX, and X, and is typically used in situations involving vitamin K deficiency or warfarin reversal but does not specifically address factor VIII deficiencies. Factor IX is a different clotting factor altogether, associated with hemophilia B, not A. Recombinant Factor VIII is a genetically engineered form of factor VIII that is used to treat hemophilia A but is not the frozen component derived from plasma.
