• Chapter 21:2

• Procedure 21:1 A, B,C, D, E, F


20:1 Measuring/RecordingHeight and Weight

• Use: to determine if a patient is overweight or underweight

• Height & Weight charts are based on averages

• Must be accurate

• When and why measurements are required ?

• Daily weights are commonly taken in hospitals– why?

(continued)


Height & Weight

• Measurements:– are routinely performed on admission to hospitals, LTC,

doctors visits

– Provide Information needed for performing and evaluation of certain laboratory tests

– Calculation dosages of certain medications—• In all children

• In all complex intravenous drip medications

• Height, weight, head circumference:– Monitored frequently in children due to rapid growth

– Commonly compared to the National Center for Health Statistics ( NCHS) growth graph

– Goal it to identify early growth and developmental conditions in children

conditions
