B) When the body responds to specific self-antigens to produce antibodies against its own cells, a severe immune response results.
C) Graft-versus-host disease would result making the patient very ill.
D) The patient would need to have suppressor T cells infused daily to maintain the heart.

Answer to Question 1

A
Feedback:
Transplantation of foreign tissue (e.g., moving a heart from a donor to a sick patient) results in an immune reaction. Matching a donor's human leukocyte antigen markers is important as closely as possible to those of the recipient because histocompatability is essential. The more closely the transplanted heart matches the recipient, the less aggressive the immune response will be to the donated tissue. Graft-versus-host disease occurs only in stem cell or bone marrow donations, not organ transplantation. Suppressor T cells cannot be transfused like blood because they must be produced by the body to function appropriately.

Answer to Question 2

A
Feedback:
Multiply the child's weight times the mg/kg: 30 5 = 150 mcg/dose.
