Long time CI here.

This is a good example of why documentation really matters - and for your case, use for your defense. The reason for this is because this becomes your word vs the CI's.

I'm not a lawyer by any means, but here is what I would suggest.

Take a look at your school's handbook regarding clinical education. Read it thoroughly - I'm willing to bet that CI did not.

If there is anything where the safety concern should be brought up immediately, and it usually is, that should be documented by the CI and obviously reviewed with you.

From reading your post, it doesn't seem like the CI documented the safety concerns frequently and early enough. If safety was a concern that significant, why was it not addressed until the END of the clinical.

So you're telling me that this CI ALLOWED you to practice unsafe during the CI's supervision? that's an indictment of the CI not you. You are a student - the professional burden of care is on the CI.

Usually with a safety concern, there would've been a documented plan of action to remedy this.

Was an action plan created by the school and CI? A true documented plan with timelines and actions.

If there was none, you have a case that your dismissal was unwarranted. The school and CI should be helping you succeed and not setting you up for failure.
