Ch 32: Skin integrity and wound care Flashcards
What is the skin in reference to infection
What does a skin integrity protect from
What is contained within the dermis
What does the subcutaneous tissue contain more of and what does it ensure
The skin is the first line of defense

The skin integrity protects from potential or life-threatening conditions
Within the dermis we have
- nerves
- sweat glands
- sebaceous glands
- hair follicles
subcutaneous tissue:
-contains more circulation V dermis
-ensures nutrients for healthy skin and hair

What are the functions of the skin and mucous membranes
Barrier Sweat/shiver Body image touch Produced by sun Immune meds Excretions 
*Protect: barrier V water microorganisms damaging UV rays
Temperature regulation: sweat/shiver
Psychosocial: self-esteem
sensation
vitamin D production: stimul by sun
immunologic : triggers immunological responses when been broken
absorption: meds
* *elimination: excrete water, electrolytes, and nitrogenous wastes in sweat
Within factors that affect the skin:
how do we defend against harmful agents
what is resistance affected by and how
why must we ensure intake in healthy diet
what type of circulation is needed
Unbroken and healthy skin/mucous membranes defend v harmful agents
Resistance to injury affected by age: loss of collagen
Ensuring intake and healthy diet to be resistant the injury
Adequate circulation needed to meeting cell life
What is the skin of someone who is younger than 2YOA look like
What does the skin become with age
As we age what is attributed to easily damaged skin (tears)
 what does impaired circulation and collagen formation lead to
Skin is thin and weak leading to high risk of infection due to easily injured
Child can becomes increasingly resistant to injury infection with age
With age: epidermal cell Maturation is prolonged leading to easily damaged skin
Circulation and collagen formation impaired = ⬇️ elasticity ⬆️ tissue damage from pressure

Give a few examples regarding older age related changes
Sub q
Sweat
Melanocyte results
Tears
TThinning of subcutaneous tissues
decreased sweat gland activity (don’t bathe as much)
melanocytes ⬇️=⬆️ melanomas risks
collagen fibers disorganized increasing tears and irritation
Who is most susceptible to skin injuries
Define a wound
What is the difference between mechanical and physical injuries
What does care of a wound depend on
You’re very thin and obese patients most susceptible to injury
 wound: breaker destruction in normal skin integrity
Mechanical: surgical incision
physical injury: burn
Care of wound depends on wound type
Intentional V unintentional
Opened v closed wounds
Acute V chronic
What does a complex result from and how does it develop
Intentional: planned/invasive therapy
Unintentional: trauma accident
Opened: skin surface broken
closed: soft tissue damaged
- from blow
Acute: short
Chronic: over three months
Complex: results from multiple things gets progressively worse
Define: Incision contusion abrasion laceration puncture penetration avulsion
Incision : Aligned wound edges
contusion : Bruise with blunt instrument
abrasion : scraping of epidermal skin
laceration: tear in skin and tissue 🚫aligned
puncture :
penetration : For an object entering skin in lodging
avulsion: tearing of structure from natural position
What is the most important principle of wound healing how does a body respond to trauma to any of its parts
What kind of blood flow is essential for wound healing
What health states may prolong healing
Wound healing #1 hand hygiene!!
Body responds systematically to trauma

Ensure adequate blood flow proper nutrition (⬆️ proteins)for wound healing 
Diabetics and her problems me prolong healing

What are the phases of wound healing briefly describe each
Wound healing:
- Hemostasis: IMMEDIATE constriction of blood vessels and clotting
- Information: 2 to 3 days white blood cells move to wound
- Proliferation phase: several weeks new tissue built (granulation)
-  Maturation: collagen remodeled and scar
Give related information for hemostasis
What is hemostasis Give the definition What is formed? what are 3 characteristics What is simulated 
Hemostasis = immediate

Definition: blood vessels constrict blood clotting begins,
Exudate formed with  swelling and pain, red
Platelets stimulate cells to migrate and participate in other phases
Give over related information for the inflammatory phase
How long does it last Give definition What is ingested what is released  what is the body response 
Lasts 2 to 3 days
Definition: white blood cells (leukocytes/macrophages) moved to wound
White blood cells ingest debris released growth factor that attracts fibroblast to fill wound
:think inflammation: GENERALIZED BODY RESPONSE 
- fever/chills
- fatigue
- malaise
Give all related information for the proliferation phase
How long does it last
Give the definition
What is formed and what does that form
Lasts several weeks

Definition: new tissue built to fill wound by fibroblasts
Granulation tissue (pink) forms foundation for scar tissue -New tissue new blood cells
Give all related information for the maturation phase of wound healing
Final: begins three weeks post injury ➡️for months and years
Definition: collagen remodeld (scar formed) scar becomes flat thin white
What are local factors affecting wound healing
Pressure Desiccation: dehydration Maceration: overhydration = breakdown of skin Necrosis edema
 what are systemic factors affecting wound healing
(Think overall body what do we do that we’re not conscious of in regards to wounds)
Age: children healthy adults more rapidly
Circulation oxygenation
-if no blood flow there is a wound healing delay
Nutritional status
Wound etology: affects wound processes
Health status
-cortical steroids/radiation delay healing
-non-adherence to treatment plan
