Comprehensive Respiratory Therapy Exam Preparation Guide, Fourth Edition is the ultimate study guide for respiratory therapy students preparing to take the NBRC TMC and CSE exams. Thousands of people take the NBRC TMC and CSE each year, but only about half of those test-takers are awarded the credentials needed to become a Certified or Registered Respiratory Therapist. Newly updated to reflect the changes to the 2020 NBRC, the Guide and its accompanying web resources comprise all the content, strategies, and tools you'll need to succeed. As long-time educators and professionals, authors Al Heuer and Narciso Rodriguez know exactly what it takes to pass the exams, and NBRC hopefuls who utilize this powerful resource will reap the benefits of their experience. The Preparation Guide is specifically designed to help students optimize their preparation--and avoid the common pitfalls many encounter.
