Skin & Aspects Of Thermoregulation

Question 1

What system does skin belong to

Answer 1

Integumentary system

Question 2

3 layers of the skin

Answer 2

Epidermis, dermis and hypodermis

Question 3

What does a keratinocyte do

Answer 3

Have a role in protection, forms a tight barrier to prevent unwanted substances entering body

Question 4

What cell is found in the dermis

Answer 4

Fibroplasts

Question 5

Cyanosis and how would you identify it

Answer 5

Lack of oxygen causing bluish colour in the skin, lips and nail beds
Looking at where skin is thin

Question 6

Thermoreceptors

Answer 6

Gives the body ability to detect heat and cold in the environment

Question 7

Adipose tissue

Answer 7

Regulating whole body energy and glucose homeostasis

Question 8

Sweat glands

Answer 8

Regulates body temperature controlled by sympathetic NS

Question 9

Blood vessels

Answer 9

Delivers blood to organs and tissues in body

Question 10

How does pressure affect pressure ulcers?

Answer 10

Lack of enough blood flow can cause the affected tissue to die

Question 11

How does moisture affect pressure ulcers

Answer 11

Leads to direct breakdown of the skin, stops resistance

Question 12

How does shear affect pressure ulcers

Answer 12

Skin stays in 1 position, rest of body moves

Question 13

How does friction affect pressure ulcers

Answer 13

Skin coming into contact with abrasive surface, skin exposed to bacteria

Question 14

How does friction affect pressure ulcers

Answer 14

Skin coming into contact with abrasive surface, skin exposed to bacteria

Question 15

Stage 1 of pressure ulcers

Answer 15

Intact skin with non-blanchable redness of a localised area usually over a bony prominence

Question 16

Stage 2 of pressure ulcers

Answer 16

Partial thickness loss of the dermis presenting a shallow open ulcer with a pink/red wound bed

Question 17

Stage 3 of pressure ulcers

Answer 17

Full thickness tissue loss where subcutaneous fat may be visible but bone, tendons or muscles not exposed

Question 18

Stage 4 of pressure ulcers

Answer 18

Full thickness tissue loss with exposed bone tendon or muscle
Often includes undermining or tunnelling

Question 19

Stage 4 of pressure ulcers

Answer 19

Full thickness tissue loss with exposed bone tendon or muscle
Often includes undermining or tunnelling

Question 20

Why does skin subjected to harmful level of pressure appear pale initially

Answer 20

Blood flow is reduced, not enough oxygen

Question 21

When the pressure is relieved, the skin quickly becomes red due to a physiological response, what is this called

Answer 21

Reactive hyperaemia

Question 22

What is prolonged inches caused by and what does ischaemia cause cells to do?

Answer 22

Prolonged inches is caused by continued pressure and ischaema causes blood cells to aggregate
