An 85-year-old patient comments during his annual physical examination that he seems to be getting shorter as he ages. The nurse should explain that decreased height occurs with aging because:
a. Long bones tend to shorten with age.
b. The vertebral column shortens.
c. A significant loss of subcutaneous fat occurs.
d. A thickening of the intervertebral disks develops.
ANS: B
Postural changes are evident with aging; decreased height is most noticeable and is due to shortening of the vertebral column. Long bones do not shorten with age. Intervertebral disks actually get thinner with age. Subcutaneous fat is not lost but is redistributed to the abdomen and hips.
