CCTN Practice Test Questions GRADED
A + 2025-2026
acute rejection with lung transplants and treatment - ANS-takes place at least once in all lung
transplant recipients, usually within the first 3 months. Symptoms are coughing, shortness of breath,
weakness, elevated temp, low blood o2 levels, pulmonary infiltrates, and pulmonary effusions.
Treatment is high-dose corticosteroids and proper immunosuppressive therapy. If left untreated,
chronic rejection will follow.
chronic rejection with lung transplants - ANS-typically observed one year post transplant. Chronic
lung rejection causes the bronchioles to become swollen and fibrose. Inflammation can lead to
complete bronchiole obstruction. Treatment is highly individualized and takes into account the
recipients current immunosuppressive regimen. chronic lung rejection has a death rate of 40% or
higher at 3 years post-diagnosis.
best way to diagnose acute and chronic rejection in lung transplants - ANS-direct microscopic
examination of tissue from lavage, brush, fine needle aspiration, transbronchial biopsy, or wedge
biopsy. Less effective methods include chest x-ray, pulmonary function tests and bronchocopic
examination.
different types of infection related to lung transplantation - ANS-morbidity and mortality in lung
transplant patients commonly results from infection in the first 3 months post transplant. Common
infections include early bacterial pneumonia, late bacterial pneumonia, Cdiff, Fungal, Viral or
parasites.
medical tests recommended for lung transplant evaluation - ANS-chest xray PA and lateral.
Quantitiative ventilation-perfusion scan, also known as VQ scan which is divided into 2 sections
1=injection of contrast medium IV hich is illuminated as it moves into the arteries of lungs indicating
which lung receives better blood supply. 2=patient inhales contrast medium to indicate which lung
takes in more o2 duing inspiration. 12 lead EKG. transesophageal echo. pulmonary function tests.
arterial blood gases. o2 desaturation study. 6-minute walking distance. DEXA scan.
when is time right for a lung transplant - ANS-objective and subjective factors are used to decide
when the time is right for a lung transplant. The patient must meet criteria such as life expectancy is
<24-36 months without transplant. Lung disease can potentially affect the patient's other organs.
quality of life has significantly deteriorated. risk vs reward is weighed.
