CCTN: Lung and Heart Exam Questions
And Answers 2025 Update.
Acute rejection with lung transplants and treatment - Answer✔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 - Answer✔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 - Answer✔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 - Answer✔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 - Answer✔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 - Answer✔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
