Question 1

A lung transplant recipient develops a new obstructive pattern on pulmonary function testing at 18 months post-transplant with an FEV1 decline of 25% from baseline. This is MOST consistent with:

Accepted Answer

Bronchiolitis obliterans syndrome (BOS)

Answer

Bronchiolitis obliterans syndrome is the most common form of chronic lung allograft dysfunction, characterized by progressive obstructive airflow decline.

Question 2

Which electrolyte abnormality is MOST commonly associated with tacrolimus and cyclosporine use in transplant recipients?

Accepted Answer

Hyperkalemia

Answer

Calcineurin inhibitors cause hyperkalemia by impairing renal tubular potassium excretion through aldosterone inhibition and direct tubular effects.

Question 3

A transplant nurse is educating a renal transplant patient about food safety. Which of the following instructions is MOST appropriate?

Accepted Answer

Raw shellfish and undercooked meats should be strictly avoided

Answer

Immunosuppressed transplant recipients are at high risk for foodborne illness from pathogens like Listeria and Vibrio, making raw shellfish and undercooked meats dangerous.

Question 4

The primary purpose of panel reactive antibody (PRA) testing in transplant candidates is to:

Accepted Answer

Identify pre-formed antibodies that could cause hyperacute rejection

Answer

PRA testing detects pre-formed donor-specific antibodies (DSA) that can mediate hyperacute or antibody-mediated rejection upon exposure to the donor organ.

Question 5

A post-liver transplant patient on prednisone and tacrolimus reports new-onset polydipsia, polyuria, and fatigue. Fasting glucose is 210 mg/dL. The MOST likely diagnosis is:

Accepted Answer

New-onset diabetes after transplantation (NODAT)

Answer

New-onset diabetes after transplantation (NODAT) is common and is driven by glucocorticoid-induced insulin resistance and calcineurin inhibitor-mediated beta-cell toxicity.
