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

1. what are pressure injuries caused by?

decreased circulation
increased mobility
balanced diet
adequate hydration

Explanation:

• For question 7: Pressure - reducing devices like special mattresses or cushions are mainly used to redistribute pressure. This helps in preventing pressure - related injuries (such as bedsores) by not allowing prolonged and excessive pressure on a particular area of the body.
• For question 8: As adults age, their immune function decreases. Also, the skin becomes thinner. A thinner skin is more vulnerable to damage, and a decreased immune function means the body is less able to fight off potential pathogens that can cause infections.
• For question 9: Pressure injuries occur when there is prolonged pressure on a body part. This pressure can lead to decreased circulation in that area. Without proper blood flow (due to decreased circulation), the tissue can start to break down, resulting in pressure injuries.

Answer:

1. They redistribute pressure to prevent injuries.
2. Decreased immune function and thinner skin.
3. Decreased circulation.
