1Which blood type is considered the universal donor for solid organ transplantation in terms of ABO compatibility?

A.Type A

B.Type B

C.Type AB

D.Type O

Explanation: Type O donors lack A and B antigens on red cells and endothelium, so their organs do not trigger preformed anti-A or anti-B antibody-mediated hyperacute rejection. Type O is therefore the universal donor across all blood types in solid organ transplantation, identical to red-cell transfusion logic.

2A kidney candidate has a calculated panel reactive antibody (cPRA) of 98%. What does this indicate?

A.The candidate has a 98% chance of finding a compatible donor quickly

B.The candidate has antibodies against 98% of the potential donor pool and will be very difficult to match

C.The candidate is 98% likely to reject any transplant

D.The candidate's kidney function is at 98% of normal

Explanation: cPRA represents the percentage of donors in the U.S. donor pool against whom the candidate has unacceptable HLA antibodies. A cPRA of 98% means only 2% of donors are likely to be immunologically compatible, making the candidate highly sensitized. UNOS Kidney Allocation System (KAS) gives priority points to highly sensitized candidates (cPRA 98-100%).

3What is the gold standard test for detecting preformed donor-specific antibodies (DSA) prior to kidney transplantation?

A.ABO blood typing

B.Complement-dependent cytotoxicity (CDC) crossmatch

C.Single-antigen bead (SAB) Luminex assay

D.Mixed lymphocyte reaction (MLR)

Explanation: The single-antigen bead (SAB) Luminex assay is the most sensitive method for identifying and quantifying HLA-specific antibodies. It uses microbeads coated with individual purified HLA antigens to detect DSA at low levels (mean fluorescence intensity, MFI). Combined with virtual crossmatch, SAB has largely replaced CDC for sensitivity.

4The Kidney Donor Profile Index (KDPI) is used to:

A.Estimate the relative risk of graft failure of a deceased donor kidney compared to a reference population

B.Match living kidney donors to recipients

C.Calculate a recipient's wait time on the kidney transplant list

D.Determine eligibility for paired kidney exchange

Explanation: KDPI is a percentile (0-100%) derived from the Kidney Donor Risk Index (KDRI) using 10 deceased-donor characteristics (age, height, weight, ethnicity, history of hypertension, diabetes, cause of death, serum creatinine, HCV status, DCD status). A lower KDPI predicts longer graft survival; KDPI >85% kidneys are typically allocated to recipients with shorter expected post-transplant survival.

5Which infection requires the LONGEST pre-transplant work-up to ensure latent disease is addressed before immunosuppression begins?

A.Hepatitis A

B.Latent tuberculosis (LTBI)

C.Acute influenza

D.Common cold

Explanation: Latent TB infection screening (IGRA preferred over TST for transplant candidates) and treatment must be addressed pre-transplant because immunosuppression dramatically increases reactivation risk. Treatment with isoniazid, rifampin, or shorter regimens (3HP) requires weeks to months and ideally completion or substantial progress before transplant. CMV, EBV, HBV, HCV serologies are also assessed.

6Which vaccine is CONTRAINDICATED after solid organ transplantation?

A.Inactivated influenza vaccine

B.Pneumococcal conjugate (PCV) vaccine

C.Live attenuated measles-mumps-rubella (MMR) vaccine

D.Recombinant hepatitis B vaccine

Explanation: Live vaccines (MMR, varicella, live-attenuated influenza, oral polio, BCG, oral typhoid, yellow fever) are contraindicated after transplantation because immunosuppression can allow the attenuated organism to cause disease. They should be administered before transplant if indicated. Inactivated, recombinant, and conjugate vaccines are safe and recommended post-transplant.

7A psychosocial assessment of a transplant candidate identifies active alcohol use disorder. The MOST appropriate nursing role is to:

A.Refuse to advocate for listing under any circumstance

B.Coordinate referral to addiction services and document a structured period of sobriety per program policy before listing

C.Allow listing immediately with no additional intervention

D.Limit teaching about post-transplant medications because the patient will not adhere

Explanation: Most U.S. liver transplant programs require an evaluation by addiction specialists and a documented period of sobriety (often 6 months for alcohol-associated liver disease, though policies are evolving toward individualized assessment for severe alcohol-associated hepatitis). The CCTN coordinates referrals, supports treatment, and documents progress without making unilateral listing decisions.

8A virtual crossmatch is performed by:

A.Mixing donor cells with recipient serum in vitro and observing complement-mediated lysis

B.Comparing the donor's HLA typing against the recipient's known unacceptable antigens defined by SAB testing

C.Performing flow cytometry with donor lymphocytes and recipient serum

D.Measuring serum creatinine in both donor and recipient

Explanation: A virtual crossmatch compares the donor's HLA antigens (from typing) against the recipient's unacceptable antigens (UAs) listed in UNet, derived from SAB Luminex testing. If the donor expresses any UA, the virtual crossmatch is positive and the offer is typically declined or requires desensitization. Virtual crossmatch enables faster organ allocation than waiting for a physical crossmatch.

9Which test is most appropriate to evaluate cardiac risk in a kidney transplant candidate with diabetes and a history of coronary disease?

A.Chest X-ray only

B.Stress imaging (e.g., dobutamine stress echocardiogram or pharmacologic myocardial perfusion imaging)

C.Routine resting ECG only

D.Carotid duplex ultrasound

Explanation: AHA/AST guidelines recommend non-invasive stress imaging in kidney candidates with multiple cardiac risk factors (diabetes, prior CAD, age >50, left ventricular dysfunction), because dialysis patients often cannot achieve target heart rate with exercise. Significant inducible ischemia leads to coronary angiography and possible revascularization before listing.

10A 60-year-old patient with end-stage liver disease has a MELD-Na score of 28. This score suggests:

A.Mild liver dysfunction; transplant is not indicated

B.Significant short-term mortality risk justifying high allocation priority

C.Liver function is normal

D.The patient is ineligible for transplant

Explanation: MELD-Na (Model for End-Stage Liver Disease, sodium-corrected) ranges from 6-40 and predicts 90-day mortality without transplant. A score of 28 is high — corresponding to roughly 30-40% 90-day mortality — and gives the candidate substantial allocation priority on the liver list. Status 1A is reserved for fulminant hepatic failure with <7 day life expectancy.

Frequently Asked Questions

What is the ABTC CCTN certification?

The Certified Clinical Transplant Nurse (CCTN) is a national specialty credential issued by the American Board for Transplant Certification (ABTC) for registered nurses providing direct clinical care to transplant candidates and recipients across solid organ (kidney, liver, heart, lung, pancreas, intestinal) and vascularized composite allotransplantation (VCA) populations.

Who issues the CCTN exam — ABTC or NNCO?

The CCTN is issued by the American Board for Transplant Certification (ABTC), not NNCO. ABTC also offers the CCTC (Certified Clinical Transplant Coordinator), CPTC (Certified Procurement Transplant Coordinator), and CTBS (Certified Tissue Bank Specialist). Each addresses a distinct transplant role; CCTN focuses on bedside and outpatient nursing care.

How many questions are on the CCTN exam and how long is it?

The ABTC CCTN exam consists of 175 multiple-choice questions delivered via computer-based testing through ABTC's testing partner. The exam covers pre-transplant evaluation, immunosuppression, rejection, infection management, long-term care, and professional practice across all solid organ transplants and VCA.

How much does the CCTN exam cost in 2026?

Per ABTC, the application fee is $150 and the exam fee is $350, for a total of $500. Recertification (every 3 years) requires continuing education credits and a separate recertification fee. Verify current pricing on the ABTC website at https://abtc.net/candidates/certification-examinations.

What are the eligibility requirements for the CCTN?

Candidates must hold a current, unrestricted RN license and meet ABTC's clinical experience requirement (typically 12 months of full-time equivalent transplant nursing experience within a defined recent timeframe). Verify exact current requirements directly with ABTC at https://abtc.net.

What topics does the CCTN exam cover?

The exam covers pre-transplant evaluation (HLA, ABO, KDPI, MELD-Na/MELD 3.0, cPRA), immunosuppression (induction agents, maintenance regimens, drug interactions, troughs by organ), rejection diagnosis (Banff 2022, TCMR, AMR, surveillance biopsy and bronchoscopy), infection management (CMV, PJP, BK, EBV/PTLD, aspergillus), long-term complications (PTDM, NMSC, CVD, BOS, IFTA), and professional practice (OPTN allocation, UAGA, ethics).

How should I prepare for the CCTN exam?

Use the ABTC handbook and content outline as your roadmap. Study the AST IDCOP guidelines, KDIGO 2017 living donor evaluation, Banff 2022 update, ISHLT lung guidelines, and current OPTN policy. Use ITNS Core Curriculum for Transplant Nursing. Aim for 80%+ on practice questions consistently and review weak areas — particularly immunosuppression interactions and rejection management.

How long is CCTN certification valid?

ABTC CCTN certification is typically valid for 3 years and renewed via continuing education credits and a recertification fee, or by re-examination. Maintain CE focused on transplant nursing topics. Confirm exact requirements with ABTC at the time of recertification.
