A 49-year-old man is involved in a motor vehicle

A 49-year-old man is involved in a motor vehicle accident, resulting in large amounts of blood loss and hypotension. He is initially given normal saline at the accident site, and on arrival at the hospital, the trauma team orders an emergent blood transfusion with type O “universal donor” packed red cells. Which of the following is a possible complication of unmatched type O blood?

(A) type O donors have a higher incidence
of hepatitis C virus
(B) type O donors have a shorter survival
time when transfused than do other cell
types
© at times type B blood may be mistyped
as type O
(D) type O donors may have high titers of
anti-A and anti-B in their plasma
(E) conversion of the recipient to type
O blood

solution:

Anti-A and anti-B in the donor plasma are usually absorbed in the recipient’s tissues but have the capacity to harm recipient cells
