Question

mr. jones has type a blood and needs a transfusion. what type(s) could he safely be given?
a type a only
b type a or type ab
c type ab only
d type a or type o
e type o only

Explanation:

Blood transfusion compatibility is based on the presence of antigens and antibodies. Type A blood has A antigens and anti - B antibodies. Type A blood can receive Type A (as it has the same antigen) and Type O (Type O has no A or B antigens, so it won't cause an immune reaction with the anti - B antibodies in Type A blood). Type AB has B antigens which would react with the anti - B antibodies in Type A blood.

Answer:

D. Type A or Type O
