Final Thoughts

So there you have it. I hope that this study guide can serve as a great review for your Therapeutic Procedures Final Exam. I realize that each Respiratory Therapy program is different, so I may not have included a question about every single topic that you’ll see on your final exam. Still, if you go through this information, I have no doubt that you can boost your knowledge and improve your score at the same time. And that’s what it’s all about! I wish you the best of luck and as always, breathe easy my friend.
