1. What is the meaning of the terms: autograft, heterograft, xenograft?
2. What type of graft would it be if a kidney is obtained from a spouse?
3. Are the nonfunctioning kidneys removed before the new kidney is transplanted?
4. What is the location where the new kidney is grafted into the recipient's body?
5. Why must immunosuppressive drugs be used when transplants of this type are carried out?
6. How long must the recipient take such immunosuppressive drugs?
7. What is the current success rate of renal transplants in terms of 3-year survival? 5-year survival? 10-year survival?
8. What are the dietary precautions (if any) that must be followed after a kidney transplant?
