Question

1. which layer of the skin contains collagen and elastin fibers?

○ epidermis
○ dermis
○ hypodermis
○ subcutaneous layer

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 skin’s moisture level.
○ they make the skin more elastic.
○ they reduce the need for a healthy diet.

1. why is it important to frequently reposition residents to prevent pressure injuries?

○ it increases skin oil production
○ it cools the skin
○ it reduces prolonged pressure on one area
○ it increases skin thickness

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

○ shear
○ prolonged pressure
○ friction
○ body weight

1. why is older adult skin more prone to bruising?

○ increased skin hydration
○ thinner skin and more fragile blood vessels
○ enhanced immune response
○ more fatty tissue under the skin

Explanation:

Question 6

The skin has three main layers: epidermis (outer, mainly epithelial cells), dermis (middle, contains connective tissue with collagen and elastin fibers), hypodermis/subcutaneous (fatty layer). So the dermis has these fibers.

Pressure - reducing devices like special mattresses or cushions work by spreading out the pressure on the body. They don't increase skin moisture, make skin more elastic, or reduce the need for a healthy diet. Their key benefit is redistributing pressure to prevent injuries (like pressure ulcers).

Frequent repositioning of residents is done to avoid having pressure on one area of the body for too long. Prolonged pressure on one area can lead to pressure injuries. It doesn't increase skin oil production, cool the skin, or increase skin thickness.

Answer:

B. Dermis
