1
Q

Q

how does skin change w age in terms of elastin, collagen, subcut fat and muscle tone? What risks does this introduce for the older adult?

A
  • elastin, collagen, subcut fat + muscle tone is lost

- loss of collagen increases the risk for shearing + tearing injuries

Q

How does the skin change w age in terms of sweat + sebaceous glands? What risks does this pose for the older adult?

A
  • Sweat + sebaceous glands decrease in # and function which results in dry skin
  • decreased response of the sweat glands to thermoregulatory demand puts older adults at greater risk for heat stroke.

Q

how the skin change w age in terms of vascularity and fragility? What risks does this pose for the older adult?

A

Vascularity diminishes + fragility increases. As a result, minor trauma may produce senile purpura (red discoloured areas).
