Are you ready to learn about Airway Clearance Therapy? I sure hope so because that is what this study guide is all about. As a Respiratory Therapist, this is definitely a topic that you must know — especially as a student.
The good news is — the practice questions in this study guide can give you a good understanding of everything you need to know.
Actually, this information correlates well with Egan’s Chapter 43, so you can use it to help prepare for your exams. So if you’re ready, let’s dive in.
Before we begin, does your school use the Egan’s Workbook as mine does? If I had to guess, I’d say so since most RT programs use it. Don’t get me wrong, it’s a solid workbook that can be helpful at times. The problem is, it takes way too long to look up all the answers.
We have the perfect solution to this problem. We looked up all the answers for you so that you don’t have to waste any more of your valuable time. I know, awesome, right? You can get access now inside our Workbook Helper. 🙂
Airway Clearance Therapy Practice Questions:
1. What is the primary goal of airway clearance therapy?
To help mobilize and remove retained secretions with the ultimate aim to improve gas exchange, promote alveolar expansion, and reduce work of breathing.
