I'm a new nurse who is presently working 12 hr night shifts on a busy general post-op surgical floor. (Soon moving to days, however!!!

) I feel so very overwhelmed/dumbfounded

at times and have days when I feel plain stupid..

.. like I don't remember anything from nursing school, although I was an "A" student with 2 separate BS degrees (in biology from a long time ago and most recently in nursing).
On some days, I honestly feel like I need to go back and re-take Med-Surg again but.... I honestly just don't remember ever discussing some of the surgeries, procedures, and situations that arrive on our floor from the OR.
I wondered if there was some type of practical handbook for post-op surgical care for nurses that anyone would recommend? 'Something I could have on the floor with me to look up information to define what surgical procedures are done on patients and what should be monitored.. other than the obvious: VS, post-op bleeding, labs, respiratory, etc?
I've been looking around on the internet, but all I keep coming up with are the huge general nursing medical-surgical textbooks.
Suggestions, anyone?
thanks, Jeanie
