It is a tough call. On one hand you have the added education and understanding that will allow you to enhance patient care, even at your current scope. However, you also leave yourself at risk for PTSD because you will inevitably encounter that patient you could have saved because you knew how to save them. Afterall, you will be trained, but you will either lack the equipment or worse, the conviction to exceed your scope to save a life. I say worse because you cannot win, either you risk an end to your career and deprive any future patient of your expertise; or you live with the guilt of knowing what you could have done, but didn't.
It's your heart. We can't tell you how to follow it.
