A nurse needs to obtain anthropometric measures of an 80-year-old client. Which of the following statements is true regarding this situation?

A. Muscle atrophy, which typically occurs in older adults, may actually reduce BMI, not increase it, because muscle mass decreases with age. B. Height may decrease due to changes in bone density. As people age, bone density decreases, and the vertebrae can compress, leading to a loss in height. This is a common occurrence in older adults. C. Increased skin elasticity will affect the waist-hip ratio. Skin elasticity does not directly affect the waistto-hip ratio. The waist-to-hip ratio is more related to fat distribution than to skin elasticity. D. Increased muscle mass will affect the mid-arm circumference measurements. Older adults typically experience muscle loss, not an increase in muscle mass, so this statement would not be accurate for an elderly client.
