  A) To manufacture antibodies to the foreign proteins
  B) To stimulate wound healing
  C) To combine with a complement to cause a massive inflammatory reaction
  D) To prevent an inflammatory reaction against the transplanted heart

Question 2

Answer to Question 1

D
Feedback:
Effector or cytotoxic T cells are aggressive against nonself-cells, releasing cytokines that can either directly destroy a foreign cell or mark it for aggressive destruction. If the transplanted organ is attacked by cytokines, it will be destroyed, referred to as organ rejection. As a result, inhibition of these killer T cells is essential to continued organ function in the transplanted organ. Blocking T cells would not manufacture antibodies, stimulate wound healing, or trigger a massive inflammatory response.

Answer to Question 2

B
Feedback:
As cardiac output improves, so does urinary output due to increased renal perfusion. Respiratory rate and heart size would not be impacted by the drug, although ventricular hypertrophy is a common finding in patients with heart failure. Heart rate would decrease as the force of contraction increases, ejecting more blood with each contraction.
