Neonatal and Pediatric Sample TMC Practice Questions (2023)

Respiratory therapists are known for diagnosing and treating adults, but they must also provide care for neonatal and pediatric patients. This involves learning the key differences in how the respiratory system develops and functions at various stages in life.

It also means that respiratory therapy students must develop an understanding of this topic. In this guide, we’ve listed some sample TMC practice questions on neonatal and pediatric respiratory care.

This can help you practice and prepare for the real-life questions that will be featured on the licensure exam offered by the NBRC.
