Question

The registered nurse is teaching a student nurse about the criteria for a deceased donor to donate an organ. Which student nurse's statement indicates effective learning?

A. "Diabetes mellitus has no effect on organ transplant."
B. "Immunocompromised donors can donate their organs."
C. "Donors should be free from active intravenous drug abuse."
D. "Donors with compromised cardiovascular health can be included."

Answer 1

The correct statement about criteria for organ donation is that donors should be free from active intravenous drug use. Blood relatives are preferred as donors due to similar MHC molecules, and immunosuppression is used to prevent organ rejection.

Step-by-step explanation:

The student nurse's statement that indicates effective learning is: "Donors should be free from active intravenous drug abuse." This criterion is essential because donors must not have any infections or behaviors that could compromise the safety and effectiveness of the transplanted organ.

Blood relatives are often preferred as organ donors because they are more likely to have similar immunogenetic backgrounds, including Major Histocompatibility Complex (MHC) molecules. A closer MHC match between the donor and recipient reduces the risk of organ rejection by the recipient's immune system.

The role of immunosuppression in transplantation is crucial, as it helps to prevent the immune system from attacking the transplanted organ. Immunosuppressive drugs, like cyclosporine A, are used to suppress the immune response, but achieving a good MHC match remains important for the success of the procedure.
