Cardiopulmonary pathology is the study of diseases that affect the heart and lungs. Some examples include:
- Congestive heart failure (CHF)
- Cystic fibrosis
Respiratory therapists are responsible for treating patients with these conditions, which is why students develop a strong understanding of each type.
In this guide, we’ve listed some sample TMC practice questions on the topic of cardiopulmonary pathology. This can help you practice and prepare with questions similar to what you’ll see on the licensure exam offered by the NBRC.
Note: We didn’t include the correct answers on this page so that you can test your knowledge. If you want to see the correct answers (with detailed rationales), just simply download the digital study guide.
