Simplifying complex information, this workbook focuses on the most important concepts in Egan's Fundamentals of Respiratory Care, 9th Edition. It makes learning easy by using real-life examples, humor, and a wide range of activities. By highlighting key points, it helps you answer three basic questions: What do I need to know? Why do I need to know it? How will I use it? An understandable and engaging approach breaks down essential information into manageable chunks. Chapter overviews introduce topics and explain how and why each applies to the practice of respiratory care. A review of chapter objectives ensures that you understand the primary concepts from the text. NBRC-style review questions help you prepare for the CRT and the written portion of the RRT exam. Vocabulary review exercises include matching, fill-in-the-blank exercises and crossword puzzles to test your mastery of key terms and acronyms. Case studies ask you to apply concepts to the real world. Critical-thinking questions ask you to analyze potential rewards and pitfalls in applying your knowledge to a clinical environment. Web links are suggested for further research and study. Answers to all questions/activities, with references to the textbook and rationales, are included on Evolve Student Resources.
