Final answer:
An infusion of plasma or blood may lead to thrombocytopenia, a condition in which there are too few platelets in the blood. Thrombocytopenia can result in impaired blood clotting and increased risk of bleeding.
Step-by-step explanation:
Platelets are critical to hemostasis, the stoppage of blood flow following damage to a vessel. If there is an insufficient number of platelets, called thrombocytopenia, blood may not clot properly, and excessive bleeding may result. Infusions of plasma or blood may lead to thrombocytopenia if the donor's blood has a low platelet count. The recipient's body may not receive an adequate number of platelets, leading to impaired clotting ability and increased bleeding risk.
