        Height and Weight
 Assess the client’s ability to stand
 Determine whether current clothing is
  similar to that worn previously
Obtain accurate weight
Client incurs no injury
Client maintains privacy
               Standing Scale
   Check identification band
   Place scale near client
   Calibrate scale to zero
   Ask client to remove shoes and to step on scale
    and stand still
   Electronic Scale: Read weight after digital
    numbers have stopped fluctuating
   Balance Scale:Slide the larger weight into the
    notch most closely approximating the client’s
    weight. Slide the smaller wt. to the so that the
    balance rests is in the middle. Add 2 nos.
Ask client to step down.
Wipe scale with appropriate
Cleanse hands
