1. Which preservation solution is most commonly used for kidney preservation during cold storage? → University of Wisconsin (UW) solution
2. Which lifestyle modification is most important to counsel a transplant recipient about for long-term cardiovascular health? → Smoking cessation, regular exercise, and blood pressure management
3. There are several signs of decreased cardiac output in heart recipients. → Jugular venousdistention
4. Renal artery stenosis after kidney transplantation typically presents with which clinical findings? → Hypertension that is difficult to control and rising creatinine
5. What is the most important nursing assessment parameter in the first 24 hours after kidney transplantation? → Hourly urine output measurement
6. Which type of rejection occurs within minutes to hours after transplantation and is caused by preformed antibodies? → Hyperacute rejection
7. A pancreas transplant recipient's fasting blood glucose rises from 90 to 210 mg/dL on post-operative day 14. What should the nurse suspect FIRST? → Graft rejection or thrombosis
8. A patient taking tacrolimus is prescribed rifampin for tuberculosis. What effect should the transplant nurse anticipate? → Tacrolimus levels will decrease significantly due to CYP3A4 induction
9. Which finding in a liver transplant recipient at post-operative day 3 would be MOST concerning for primary non-function (PNF)? → AST >5,000 IU/L with coagulopathy and rising creatinine
10. A heart transplant patient presents with endomyocardial biopsy showing grade 2R rejection. This corresponds to which type of rejection? → Moderate acute cellular rejection
11. Which laboratory trend is MOST consistent with calcineurin inhibitor (CNI) nephrotoxicity in a stable kidney transplant recipient? → Gradual creatinine rise with supratherapeutic CNI trough levels and no proteinuria
12. What is the significance of Panel Reactive Antibody (PRA) percentage in transplant candidates? → It indicates the percentage of donor pool against which the patient has antibodies
13. Which psychological condition is most commonly seen in transplant recipients awaiting an organ on the waiting list? → Depression and anxiety
14. When counseling a female kidney transplant recipient of childbearing age about pregnancy, the transplant nurse should emphasize that: → Mycophenolate mofetil must be discontinued before conception due to teratogenicity
15. Which blood group compatibility rule is universally applied in solid organ transplantation? → ABO blood group compatibility between donor and recipient is required
16. Which transplant patient situation requires mandatory referral to social work? → Patient expresses inability to afford medications or housing instability
17. Which apnea test finding confirms brain death during donor evaluation? → No spontaneous respirations with PaCO2 rising to ≥60 mmHg or 20 mmHg above baseline
18. Mycophenolate mofetil (MMF) works primarily by inhibiting which enzyme? → Inosine monophosphate dehydrogenase (IMPDH)
19. A transplant nurse is educating a recipient about food safety. Which food should be specifically avoided to prevent Listeria monocytogenes infection? → Unpasteurized soft cheeses and ready-to-eat deli meats
20. Which complication is indicated by a sudden cessation of urine output, graft pain, and hematuria in an early post-kidney-transplant patient? → Renal vein thrombosis
21. Chest tube drainage shouldn't go over a certain amount while assessing postoperative mediastinal hemorrhage. → 200 mL in 2 to 6 hours
22. A liver transplant recipient develops new-onset hypertension and nephrotoxicity. Which immunosuppressant is most likely responsible? → Tacrolimus
23. A kidney transplant recipient on tacrolimus develops a serum creatinine rise from 1.2 to 2.8 mg/dL on post-op day 5. The most appropriate next step is: → Obtain a renal biopsy to differentiate rejection from tacrolimus nephrotoxicity
24. Which of the following is a contraindication to living kidney donation? → Uncontrolled diabetes mellitus
25. Which of the following is the most important factor in determining a patient's risk for rejection in the first year after transplant? → Number of HLA mismatches
26. What is the primary purpose of performing a liver biopsy on a donor liver before transplantation? → To assess the degree of hepatic steatosis, which affects graft function
27. The insulin type that is most frequently used to manage hyperglycemia following heart transplantation is → Short-acting regular insulin, such as Novolin R.
28. C4d deposition on peritubular capillaries is a hallmark finding in which type of renal transplant rejection? → Antibody-mediated rejection
29. How long after transplantation should female recipients wait before attempting pregnancy? → At least 1–2 years, when graft function is stable and immunosuppression is minimized
30. Acute cellular rejection is primarily mediated by which immune cells? → T lymphocytes
