Like "In what ways did they try to get the BP? Did they all use the machine, or did they use a manual BP cuff? When I was a CNA I chose not to use the BP machines, because the manual was more accurate IMO. Did they try other sites on your body than on your arm? I don't think in all the years that I had been doing CNA work I had 1 time where I douldn't get a BP somewhere on the body"
