Answer to Question 1
Correct Answer: 1
It is apparent that genetics play a role in autoimmune disorders because a higher incidence is seen in family members of people with these disorders. More than one genetic change is likely occurring to cause development of the disorders. There is no information linking estrogen to the development of an autoimmune disorder. Stress is not the only cause of the disorder. Limiting physical activity will not prevent the onset of the disorder.
Answer to Question 2
Correct Answer: 1
An autograft, a transplant of the patient's own tissue, is the most successful type of tissue transplant. A skin graft is an example of an autograft. Evidence of immediate cyanosis describes hyperacute tissue rejection. Acute tissue rejection occurs within 3 to 4 months and is not typically seen with a skin graft. Chronic tissue rejection occurs from 4 months to years after the transplant and is not typically seen with a skin graft.
