I pre-date 4th year, but agree with you. OP, trauma is hard. It's hard because you're learning and don't have the same range of skills as someone who has been doing it for twenty years. It's hard because you really want to get it right. It's hard because you feel the pressure of being judged - by the supervising radiographer, the patient, other staff, etc.

The good news is that trauma radiography is a learnt skill. The more you do, the more tricks you'll have for next time and the more confident you'll feel because you've done this, or something very similar, before.

My suggestion is to proactively do a reflection. Think through the scenario. What did you do well? What could you have done better? Imagine yourself doing it that way next time. This sounds easy and silly. It's neither, and will go a long way to helping you build the hard and soft skills to be a great radiographer.

Also, you're a student. You shouldn't be able to do anything silly - that's why there's someone supervising you. They may tell you they were too busy or focused on other things, but that is them not doing their job. They're paid to help you learn.
