We used to have this frequent flier w numerous admits w CHF. However he would often fake it or c/o other things while admitted in order to stay in the hospital where he got "great food" (his words).
We once found him laying on the floor in his room, rolling around and jerking. (He weighed over 350#...this was a real sight) A verteran RN on our floor had dealt w him many times and just yelled, "LOU! LOU! WHAT ARE YOU DOING?!!!" He honestly STOPPED the "seizure" looked up and said, "I am having a seizure!" and promptly started flipping around on the floor again!
