Unit 21 Measuring Height and Weight
Objectives • Spell and define terms. • Explain why having an accurate height and weight for each patient is important. • Describe and demonstrate how to weigh the patient on a standing balance scale, chair scale, wheelchair scale, digital scale, and bed scale.
Objectives • Describe and demonstrate how to measure a patient’s height using a standing balance scale. • Describe and demonstrate how to measure a patient using a tape measure and explain when this type of measurement is necessary.
Weight and Height Measurements • Changes in weight are frequently used as an indicator of a patient’s condition • Baseline measurements of height and weight • Usually obtained upon admission • These are usually noted on the Cardex
Weight and Height Measurements • Weights • Frequently measured when patients are given drugs to increase their urine output
Weight and Height Measurements • Weight is an indicator of the patient’s nutritional status • Measurements of weight and height • Record accurately according to facility policy • Medications may be ordered according to each patient’s size
Weight and Height Measurements • Height measurements • Feet (′) • Inches (″) • Centimeters(cm) • Weight measurements • Pounds (lb) • Kilograms (kg)
Scales • Upright scale • Mechanical lift with scale • Sling scale • Chair scale
Reading the Balance Scale • For an accurate value • Balance bar must hang freely when you begin • Lower bar • Measures in 50 pound increments • Upper bar • Measures in ¼ pound increments
Reading the Balance Scale • Short, numbered lines • Represent even number pounds • Long, unnumbered lines • Represent odd pounds
Reading the Balance Scale • Add the values of the upper and lower bars together • Refer to Figure 21-5
Obtaining the Height Measurement • To obtain the height value • Read numbers at intersection of ruler and scale frame • Refer to Figure 21-6
Measuring the Bedfast Patient • Straighten the bottom sheet so it is free from wrinkles • Make a small mark with your pen on the sheet at the top of the patient’s head
Measuring the Bedfast Patient • With the tape measure, carefully measure the patient’s body from the head to the heels • Make a mark on the sheet at the heels • Turn the patient on his or her side • Measure the distance between the marks on the sheet
Measuring the Contracted Patient • If the patient is contracted in the fetal position • Obtain height in two or three segments • Position patient in side-lying position
Measuring the Contracted Patient • Measure from top of head to waist • Measure from waist to behind knees • Measure from behind knees to bottom of heels • Write down all numbers • Add all numbers to obtain total height measurement
