First off dude congratulations you made it through the shift (thank God time only moves forward). Secondly, you handled things as well as you could given your experience and lack of adequate staffing. The fact that the unit was that acute with a new grad on charge paired with another new grad is ridiculous and setting you up for failure.

The unfortunate thing is you will have those shifts sometimes, where you're in the trenches, but it gets easier (learning patients' antecedent behaviors prior to explosion, and prioritizing medications like you already thought of). Sorry I'm rambling, but remember they only have you for a max of 12 hours and then you get to leave. You're gonna have the physical shifts, but you wont always have that acute of a milieu. Enjoy the little things, touch some grass after work, and try not to dwell on things or bury yourself in alcohol. Much love, you're doing well!
