What blood product type can a patient with A blood type safely receive?

A patient with A blood type can safely receive A type blood because it has the same antigens (A antigen) as the patient's own blood. Additionally, they can receive type O blood, which is considered the universal donor because it has no A or B antigens. This means that type O blood does not provoke an immune response in A type recipients.

Type A recipients produce antibodies against the B antigen due to the presence of anti-B antibodies. Therefore, they cannot receive B blood products, which could provoke an adverse reaction. Similarly, while AB blood can be received by AB blood type recipients, it contains both A and B antigens, making it unsuitable for a type A patient due to the potential for an immune response against the B antigen.

Thus, the correct answer identifies both types of blood that a person with A blood type can receive safely without risk of hemolytic transfusion reactions.
