I have been thinking about this constantly.. Ok so a while back my patient coded and didn't make it that i was helping take care of all day. (im a nursing student) In fear of violating any hippa regulations im going to try to make this very general but basically my patient was on the unit after having an amputation related to complications of PVD. he/she had a history of cardiac complications. with this he/she also appeared to be in acute renal failure as BUN and Creatinine were both pretty elevated. He/She refused to eat the whole shift since she said she got sick the night before. towards the end of my shift he/she got a routine glucose check and it was very low (lower then 50 was not a diabetic) so his/her nurse got an order for Dextrose IV push. Shortly after given the IV push he/she began to become more alert but then suddenly became unconscious and coded. Her vitals were WNL all day and she appeared to be in stable condition. I just dont see what could have happened for him/her to slip away so fast at first i thought maybe it was the dextrose and his/her blood sugar skyrocketed but now im thinking otherwise. does anyone have any ideas on what could of happened? at the time he/she became unconscious vitals were taken and her o2 sat was down to 80 and blood pressure had skyrocketed (does not make sense to me). Even my clinical instructor couldn't really figure it out. It just has been bothering me that i cant figure out exactly what happened i feel like i missed something that should have seen... Also throughout the whole shift the patient had 0 output, (was bladder scanned at 135ml) but had an intake of around 500ml. BUN and Cretinine levels were twice the normal limit from the day before, and updated lab results were not obtained because phlebotomy tried too many times unsuccessfully (there was a limit).
