The CTP exam has 110 questions and runs 2 hours.
These 10 free CTP questions are organized by exam domain, so you can see how each part of the Certified Transplant Preservationist blueprint is tested. Reveal the answer and explanation under each question.
An adult donor declared dead by neurologic criteria develops urine output of 700 mL/hour. Serum sodium rises from 148 to 159 mEq/L over three hours; serum glucose is 108 mg/dL and urine osmolality is 86 mOsm/kg. No diuretic or osmotic agent has been administered. These findings most strongly suggest:
Correct answer: D - Central diabetes insipidus
A donor's authorization form permits organs for transplantation without listed restrictions, but neither the donor nor a surrogate has specifically authorized vascularized composite allograft donation. Both kidneys have been accepted and their recovery plan is ready. An upper-limb transplant team now requests a graft. How should this request affect the authorized kidney recovery?
Correct answer: C - Continue kidney preparations; obtain specific authorization before upper-limb recovery.
An OPO coordinator and a preservationist have checked the donor ID, organs and laterality, and donor ABO against the required source records before recovery. Both are qualified under the OPO protocol. The recovering surgeon is on site but did not participate. How must the donor verification be completed?
Correct answer: A - Repeat the donor checks with the on-site recovering surgeon and the OPO coordinator.
While separating the liver and pancreas during recovery, the surgeon traces an artery from the superior mesenteric artery into the right hepatic lobe. There is no right hepatic branch from the proper hepatic artery; the left hepatic artery arises normally. What is the correct description for the recovery record?
Correct answer: A - Replaced right hepatic artery
For a donation-after-circulatory-death recovery, the documented protocol measures functional warm ischemia from the first sustained systolic pressure below 50 mmHg or oxygen saturation below 70%, whichever occurs first, until cold perfusion begins. Life support is withdrawn at 14:00. Systolic pressure falls to 44 mmHg at 14:08 while saturation is 84%; saturation falls to 66% at 14:12. Each remains below its threshold thereafter. Circulatory arrest occurs at 14:20, death is declared at 14:25, and cold perfusion begins at 14:28. What functional warm ischemic interval should be recorded?
Correct answer: C - 20 minutes
During an antegrade pulmonary-artery flush, the donor lungs rapidly become heavy and distended. Inflow tubing is patent, but little effluent appears at the left-atrial vent. What takes priority at this moment?
Correct answer: D - Interrupt the flush and alert the surgeon to restore pulmonary venous drainage.
Soon after a kidney is connected to hypothermic machine perfusion, flow rises markedly, but the pump cannot reach the prescribed arterial pressure. The kidney remains unevenly blanched. Pressure measurement has been checked and is accurate. Which finding would best explain this combination?
Correct answer: C - Leakage around the arterial cannula seal
An unopened bag of Belzer UW Cold Storage Solution has been kept at 20°C in a temperature-monitored stockroom. Its seal is intact, it is within its expiration date, and it has never been frozen. The solution is clear and free of visible particles. It is now needed for a cold kidney flush. What preparation follows the manufacturer's instructions?
Correct answer: A - Cool it to 4°C before preparing the ordered flush.
The histocompatibility laboratory requests fresh donor lymph-node tissue in its approved culture medium rather than formalin. Preserving viable donor lymphocytes is essential for which procedure?
Correct answer: B - Testing recipient serum against donor lymphocytes for donor-reactive antibodies
A kidney is sealed in an intact sterile rigid organ container and enclosed in two separately sealed sterile bags. Each component is suitable for use as a sterile barrier. Which assessment of this internal packaging is accurate under OPTN policy?
Correct answer: B - It meets the triple-barrier rule because the sterile rigid container counts as one barrier.
