The experience that I had that just really shook me up was when I first came off orientation on med-surg. I had a patient on BiPap with elevated BP's. I was so focused on her BP's that I just didn't see her declining resp status. Also, they assigned me a very crusty OB nurse who floated over to be CNA. She didn't get sats on any of my patients, including this one on BiPap. At the time I felt that she must know what she was doing to not get sats. No, what it was is that they don't get sats on the PP's, so it was out of her routine. So, in the morning, the day shift RT, got a sat on her and said she was about to code. Within 15 minutes at the end of my shift, she was sent to ICU, where she lived, did not code, and eventually went home.
That taught me alot. It has taught me to be so much more assertive, to use my resources, and to not become so focused on just one piece of the entire puzzle.
