The nurse is preparing to measure fat and lean body mass and bone mineral density. Which tool is appropriate?
 
  a. Measuring tape
  b. Skinfold calipers
  c. Bioelectrical impedance analysis (BIA)
  d. Dual-energy x-ray absorptiometry (DEXA)

Question 2

Which of these interventions is most appropriate when the nurse is planning nutritional interventions for a healthy, active 74-year-old woman?
 
  a. Decreasing the amount of carbohydrates to prevent lean muscle catabolism
  b. Increasing the amount of soy and tofu in her diet to promote bone growth and reverse osteoporosis
  c. Decreasing the number of calories she is eating because of the decrease in energy requirements from the loss of lean body mass
  d. Increasing the number of calories she is eating because of the increased energy needs of the older adult

Answer to Question 1

ANS: D
DEXA measures both bone mineral density and fat and lean body mass. BIA measures fat and lean body mass but not bone mineral density. A measuring tape measures distance or length, and skinfold calipers are used to determine skinfold thickness.

Answer to Question 2

ANS: C
Important nutritional features of the older years are a decrease in energy requirements as a result of loss of lean body mass, the most metabolically active tissue, and an increase in fat mass.
