You won't be asked to do important work when you go for the first time. You should practice aseptic operation, debridement and suture first, and then let you do something else in a few months. You can watch the teacher operate other things these months.
3. Remember the routine of hematuria, which is very easy to recite. X-ray and CT are the most common and the most difficult. When you go to the hospital, first find some students who are internship in imaging to learn.
Finally, there are a few points to remember. Don't be too close to the emergency room when the teacher rescues patients. They will think you are in the way. Remember the names and locations of commonly used instruments first, or you won't know what they want you to take.
I hope it will help you, please adopt it!
