Question 1

A kidney from a donor after cardiac death (DCD) is expected to have a higher rate of which complication compared to a standard criteria donor kidney?

Accepted Answer

Delayed graft function (DGF)

Answer

DCD kidneys experience warm ischemia during the withdrawal-to-perfusion interval, causing tubular injury that manifests as delayed graft function at higher rates than brain-dead donor kidneys.

Question 2

In liver transplantation, what does a MELD score of 40 indicate?

Accepted Answer

Approximately 71% 90-day mortality without transplantation

Answer

A MELD score of 40 correlates with approximately 71% mortality at 90 days without a transplant, indicating critical urgency for organ allocation.

Question 3

Which post-transplant infection is most commonly associated with the first month after solid organ transplantation?

Accepted Answer

Surgical site infections and nosocomial bacterial infections

Answer

In the first month post-transplant, nosocomial bacterial infections and surgical site infections predominate due to surgery, catheters, and hospitalization.

Question 4

What is the primary advantage of using a living donor for kidney transplantation compared to a deceased donor?

Accepted Answer

Superior long-term graft survival and minimal cold ischemia time

Answer

Living donor kidneys have superior long-term outcomes due to planned procurement, minimal cold ischemia time, and the ability to optimize recipient preparation.

Question 5

Which parameter is used to calculate the Kidney Donor Risk Index (KDRI) to assess deceased donor kidney quality?

Accepted Answer

Multiple donor factors including age, height, weight, cause of death, and creatinine

Answer

The KDRI is a composite score incorporating multiple donor characteristics to estimate the risk of graft failure relative to a reference donor.
