I worked neuro med/surg/stepdown/telemetry... So there are plenty that came to mind.
One of my favorites was a little old lady that kept trying to get out of bed (hx of both dementia and subdural hemorrhage s/p fall). She kept telling me about a wedding she had to get ready for (she had owned a co-owned a banquet hall when she was younger). She kept talking about laundry (tablecloths, napkins) that needed "fixin". So, to play into that, I went to the linen closet and got an assortment of towels and pillow cases. I took them into her room, and asked her if she would mind helping me "getting ready for the wedding". I "picked" the laundry up when she finished, and brought her "more" (same pile just unfolded again) and kept repeating that night and the next night - she never once tried to get up out of bed on me
My coworkers were kind of upset - I was the only one able to get her to buy into it
Or the little old guy, who lived on a farm his entire life (barring the time he was stationed overseas in the service). Was very combative and actually in a net bed - there were many hallucinations he had frequently. One time, when I checked on the patient, the he was there in bed, rambling on and on and on about cows on the roof, how he can't count all of them there are so many.
