Which scoring system is used to assess the quality and predicted graft function of a deceased donor kidney before transplantation?
Answer: KDRI (Kidney Donor Risk Index)
The KDRI estimates the relative risk of kidney graft failure based on donor characteristics such as age, creatinine, hypertension, and cause of death.
In donation after circulatory death (DCD), which organ is considered MOST vulnerable to warm ischemia during the withdrawal of life support phase?
Answer: Liver
The liver is most sensitive to warm ischemia in DCD donors and has the highest risk of primary non-function and ischemic cholangiopathy.
Which donor condition is classified as a 'Public Health Service (PHS) Increased Risk' behavior that must be disclosed to potential recipients?
Answer: Incarceration in the past 12 months
PHS Increased Risk criteria include recent incarceration (within 12 months) because of higher prevalence of blood-borne infections in this population.
A recipient has a calculated PRA of 85%. What does this indicate about their transplant candidacy?
Answer: They are highly sensitized and will likely need a virtual or prospective crossmatch
A PRA of 85% indicates high sensitization, meaning the recipient has antibodies against 85% of the population, requiring careful crossmatch strategy.
Which factor is part of the standard evaluation for assessing a living kidney donor's long-term renal reserve?
Answer: 24-hour urine creatinine clearance or GFR measurement
Measured GFR or 24-hour urine creatinine clearance is essential to confirm adequate bilateral renal function before nephrectomy in living donors.
Which condition in a potential lung donor would be an absolute contraindication to lung procurement?
Answer: Active aspiration pneumonia with purulent secretions on bronchoscopy
Active aspiration pneumonia with purulent secretions indicates severe parenchymal infection that would lead to primary graft dysfunction in the recipient.
In recipient evaluation for heart transplantation, which hemodynamic measurement, if severely elevated and fixed, may contraindicate transplantation?
Answer: Pulmonary vascular resistance (PVR)
Fixed, severely elevated PVR (>5 Wood units) that does not respond to vasodilator challenge increases the risk of acute right heart failure in the donor heart after transplant.
