Q

The dermis is primarily populated by ___________.

A

fibroblasts

17
Q

Functions of dermis include?

A 
nutritional support
immune surveillance
would healing
thermal regulation
hemostasis
inflammatory response
18
Q

From a wound healing stand point what is the most important protein in the body and where do they come from?

A

collagen

secreted by dermal fibroblasts

19
Q

Functions of the integumentary system?

A 
Protection
Immunity
Thermoregulation
Sensation
Metabolism
Communication
Vitamin D Synthesis

20
Q

What is hemosiderin staining?

A
  • red blood cells can lead out of dilated vessels
  • stimulated melanin get trapped in the skin
  • this causes a darkening of surrounding tissues
21
Q

Gold standard for measuring lymphedema?

A
  • volumetric measurement
22
Q

what sensation is not diminish when a pt has deep partial-thickness burn?

A
  • deep pressure
23
Q

Superficial partial-thickness burns extend into what layer of the skin?

A
  • papillary dermis
24
Q

T/F capillaries –>pre collectors–>collector nodes–>trunks–>ducts

A

TRUE

25
Q

Collectors have ______ prevent back flow

A

valves (first vessel in lymph system to have these)

26
Q

Changes in foot/ankle can lead to? (3)

A
  • altered weight distribution
  • increased pressure in areas not ready for that type of load
  • areas of ischemia
27
Q

What are the 2 main differences between the Wagner grade and UT diabetic wound classifications?

A
  • Wagner does not take into account ischemia and infection, while the UT wound classification does.
28
Q

Wagner Grade 0

A

Zone of stasis
Zone of hyperemia

38
Q

_______ may be present in superficial partial thickness burns

A
