Advanced Respiratory Therapist Exam Guide prepares readers for every testable subject on both the written registry and clinical simulations portions of the NBRC registry examination — both requirements to be awarded the RRT (registered respiratory therapist) credential. This new edition has been revised to directly tie in with the most recent NBRC examination matrix and content outline. Each chapter includes content review, self-assessment questions, and study hints. In addition, each chapter has NBRC-type review questions with rationales explaining why answers are correct or incorrect. Difficulty Level Codes and Examination Matrix Coding are also included, better preparing readers for the examination.
