Question

1. what happens to the skin as a person ages?

the fatty layer of tissue is increased.
it produces more oil and sweat.
it becomes thinner and less elastic.
it becomes more resistant to bruising.

1. what is a key benefit of using pressure - reducing devices like special mattresses or cushions?

they redistribute pressure to prevent injuries.
they increase the skins moisture level.
they make the skin more elastic.
they reduce the need for a healthy diet.

1. what are pressure injuries caused by?

decreased circulation
increased mobility
balanced diet
adequate hydration

1. which factor directly contributes to the formation of pressure injuries by reducing blood flow to tissues?

shear
prolonged pressure
friction
body weight

1. what makes older adult skin more susceptible to infections?

thicker skin layers
more active oil glands
decreased immune function and thinner skin
increased blood flow

Explanation:

• Question 6: As people age, the skin thins and loses elasticity due to reduced collagen and elastin production.
• Question 7: Pressure - reducing devices redistribute pressure to prevent pressure ulcers by avoiding prolonged pressure on tissues.
• Question 8: Decreased circulation (due to prolonged pressure) is a cause of pressure injuries as it deprives tissues of oxygen and nutrients.
• Question 9: Prolonged pressure reduces blood flow to tissues, which is a direct cause of pressure injury formation.
• Question 10: Older adults have decreased immune function and thinner skin, making them more susceptible to infections.

Answer:

1. It becomes thinner and less elastic.
2. They redistribute pressure to prevent injuries.
3. Decreased circulation.
4. Prolonged pressure.
5. Decreased immune function and thinner skin.
