A male trauma victim whose blood type is group AB Dnegative

A male trauma victim whose blood type is group AB, D-negative has a negative antibody screening test. He has been transfused with both of the group AB, D-negative units in inventory within the last hour. He is now in surgery and expected to need large amounts of blood. Of the following available units in inventory, which type should be given next? A. 30 units of group O, D-positive B. 26 units of group A, D-positive C. 10 units of group O, D-negative D. 5 units of group A, D-negative

Solution

D. 5 units of group A, D-negative

We cannot supply D-positive blood, and group O blood can be used later in case of other emergencies.
