a person with a+ blood can receive blood from which of the following types?
only a+
a+,a-,o+,o-
only o-
ab+

Explanation:

Blood transfusion compatibility is based on blood type (A, B, AB, O) and Rh factor (+ or -). A person with A+ blood has A antigens and Rh+ factor. They can receive blood from donors with A (as it has compatible A antigens) and O (universal donor in terms of ABO, as O has no A or B antigens) blood types, and for Rh factor, since they are +, they can receive + and - (as - is compatible with + in transfusion, but + cannot receive - in reverse in general cases, but here donor can be - for recipient +). So A+ (same type), A- (same A antigen, Rh - which is okay for + recipient), O+ (O blood with Rh +), O- (O blood with Rh -) are all compatible.

Answer:

A+, A-, O+, O-
