As a medical professional, it's my job to ensure that you know what is happening and that you understand how things work so that you can make an informed decision about your healthcare. If I'm talking to another medical professional, I'll use language they will know. If I'm talking to a person with no medical background, I will use language that will help them understand how things work. It's their job to word it in such a way so that you understand everything. So if you don't understand something, don't just nod and accept that you don't understand the information. Tell them you don't quite understand and ask them to use different language. I know some of us can be arrogant jerks in the medical field, but we really do have your best interest at heart and we really want you to make your best informed decision. We'll go out of our way to make sure you can do it, but we need you to let us know what you get and what you don't.
