What is a respiratory therapist?

Respiratory therapists care for patients who have breathing problems. These professionals will assess patients’ needs, monitor them, and provide treatment through the supervision of a physician. Respiratory therapists require a deep understanding of the cardiopulmonary system and standard clinical procedures. One of the ways professionals in respiratory care demonstrate their knowledge and experience is through certifications provided by the National Board for Respiratory Care (NBRC). Certifications are also a requirement in 49 states for you to receive your license to practice.  

What is the Therapist Multiple-Choice (TMC) exam?

The NBRC provides many credentials, but the first certification many respiratory therapists must pass is the Therapist Multiple-Choice (TMC) exam. Passing this exam awards you the entry-level certification called the Certified Respiratory Therapist (CRT). This guide will help you find the best resources to study for the TMC so you can be a RT as soon as possible. The test itself costs $190. It is composed of 140 multiple-choice questions, and you have three hours to answer all of them. The purpose of this test is to measure your knowledge, skills, and abilities needed to be an entry-level respiratory therapist. If you are looking to try for the more advanced-level certification, called the Registered Respiratory Therapist (RRT), your goal is to pass the TMC and achieve a high-cusp score.
