Final answer:
The best response for the nurse is to emphasize the donor's right to change their decision. Blood relatives are often preferred for organ donation due to higher genetic matching, reducing the risk of rejection. Immunosuppression is used in transplantation to prevent graft rejection.
Step-by-step explanation:
The appropriate response for the nurse to provide is: D. You can always change your mind and withdraw your consent at any point. This acknowledges the donor's autonomy and reassures that their choice to donate is reversible should they have second thoughts.
Blood relatives are often preferred as organ donors because they are more likely to be compatible matches, which reduces the risk of organ rejection. Immunogenetic similarities such as Human Leukocyte Antigen (HLA) matching are critical in transplantation. Higher genetic similarity increases the likelihood of a successful transplant without severe immune reactions.
Immunosuppression plays a vital role in transplantation, as it involves medication to suppress the immune system. This helps prevent the body from attacking the transplanted organ (graft rejection) by reducing the immune response to the organ from the recipient's body.
In the case of the supply and demand for dialysis machines, the supply primarily determines the price given the inelastic demand; people need these machines to survive, so they are willing to pay what is necessary to access them.
