CTP Organ Recovery & Procurement Logistics 3

Question 1

Before accepting an organ for transport to a recipient center, which information must be verified?

Accepted Answer

ABO blood type compatibility, organ match data, and relevant donor history

Answer

ABO compatibility, UNOS match data (including HLA and crossmatch results), and donor medical history must all be confirmed before transport to ensure safe and appropriate allocation.

Question 2

Which factor is most critical in procurement logistics planning for heart transplantation?

Accepted Answer

The heart's short total ischemia tolerance of 4–6 hours

Answer

The heart's narrow ischemia window of 4–6 hours drives all logistical decisions, including recipient selection and transport planning, more than any other single factor.

Question 3

What is the purpose of the 'back-table' procedure following organ recovery?

Accepted Answer

Inspecting, trimming excess tissue, and preparing vascular attachments on the recovered organ before transplant

Answer

The back-table procedure prepares the recovered organ for implantation by trimming, inspecting for damage, and tailoring vascular structures to fit the recipient.

Question 4

If an unexpected transport delay (e.g., flight cancellation) occurs during organ transport, what is the correct immediate response?

Accepted Answer

Notify the transplant center immediately, reassess cumulative ischemia time, and arrange alternative transport

Answer

Any delay requires immediate notification of the transplant center to reassess organ viability based on cumulative ischemia time and coordinate alternative transport options.

Question 5

What is the primary function of the UNOS/OPTN match system in organ procurement logistics?

Accepted Answer

Allocating organs to waiting recipients based on medical criteria, waiting time, and geography

Answer

The UNOS/OPTN match system uses a combination of medical urgency, compatibility, waiting time, and geographic proximity to allocate organs equitably to recipients on the national waiting list.
