The anthropometric changes observed as a patient progresses from infancy to adulthood include which of the following statement(s)?

b. A decrease in the relative size of the head from 18% to 9% of the body’s surface area occurs

c. The total surface area of the legs increases from 14 to 18%

 An accurate assessment of burn size can be made early and is important to the initial management as resuscitative fluid administration is primarily determined by overall burn size. Burn size in children is best estimated with an age-specific chart, because the child’s body proportions change with growth. The major anthropometric change involves the head and legs. The infant’s head represents 18% of the total body surface and legs 14%. In older adolescents and adults, the head represents 9% of the body surface and the legs 18%. Each upper extremity in the adult is usually considered to represent 9% of the total body surface area.
