A mismatch of blood types during a transfusion is dangerous because ________.
A) white blood cells from the donor's blood cause inflammation
B) antibodies in the donor's plasma will attack and kill the recipient's healthy blood cells
C) clotting factors in the donor's blood will cause unwanted clots known as thrombus
D) preformed antibodies in the recipient's blood will bind and clump (agglutinate) the donated cells

Question

Quizplus · Accepted Answer

When a recipient receives blood that is not compatible with their blood type, preformed antibodies in their blood will recognize the foreign blood cells as invaders and attack them. This can lead to the clumping (agglutination) of the donated cells, which can result in blockages in blood vessels and potentially life-threatening complications.
