    Q:

    		 Aplastic anemia is a condition that results in the decreased production of blood cells by the bone marrow. One known cause of aplastic anemia is autoimmune reaction against the bone marrow. A potential treatment is a bone marrow transplant to replace the immune system. Which of the following is an inherent risk associated with such a procedure?
    		 

    A

    		 The body will be devoid of an immune system during the transition period from one immune system to the other.

    B

    		 It is exceedingly difficult to oxygenate the body during the transplant due to the cessation of red blood cell production.

    C

    		 Bone integrity decreases during the transplant; this increases the risk of fractures.

    D

    		 The new immune system may mount an autoimmune attack against other tissues of the body.
