It's the end of the quarter and my brain is fried or something. Here is what I have: 82 yo male, 7 days post op from a hemicolectomy, discharged and then returns to the ER complaining of vomiting and inabilty to eat. Turns out he had a small bowel obstruction. My problem is, I need an "anticipated nursing diagnosis" and one anticipated body system to assess. I'm thinking the GI system, but honestly, how do you assess that? listen for bowel tones? He was NPO so I can't use increase fluids as an intervention. Help, Please!!
