Integumentary System Flashcards
What contents are in the integumentary system
Hair, skin, nails, mucus membranes, and glands
Key roles of the integ system
immunity
temp regulation
water balance
Eczema
also known as dermatitis
inflammation of the skin
2 types of dermatitis
contact and atopic
Contact dermatitis
Acute
Triggered by an outside source
Not related to the immune system
Atopic dermatitis
Chronic and inherited
Signs and symptoms of dermatitis
red itchy swollen skin
can have fluid filled bumps
Psoriasis
Common inflammatory skin condition
Red elevated patches with flaking
Risk factors of psoriasis
adults and family history
Signs and symptoms of psoriasis
takes different forms and appearances
can be mild to severe
Cause of psoriasis
Malfunction of the autoimmune system
production of inflammation
Rosacea
Redness of the skin
Risk factors for rosacea
ages 30-50
fair skin
Signs and symptoms of rosacea
on cheeks, nose, chin, and forehead
red lines from enlarged blood vessels
Cause of rosacea
no known cause
Some common skin changes with aging
pain sensation changes vibration changes temp and touch decreases loses elasticity age spots bruise more easily
Cellulitis
deep in the dermis and subcutaneous
Swollen warm tender area of the erythema
hard and hot
2 types of wounds
Acute and chronic
Acute wounds
cuts and surgical cuts, and burns
Chronic wounds
ulcers and infections
First degree burn
only epidermis (sunburn)
second degree burn
epidermis and dermis (blistering)
third degree burn
extends to deeper tissues
Treatment for burns
promote wound healing reduce dependant edema promote venous return prevent or minimize deformities Increase ROM
Pressur ulcer
a lesion caused by unrelated pressure resulting in damage of underlying tissues
Stage 1 pressure ulcer
Redness
no open skin
Stage 2 pressure ulcer
partial thickness skin loss
involves epidermis and dermis
Stage 3 pressure ulcer
full thickness skin loss
damage or necrosis of subcutaneous tissue
Stage 4 pressure ulcer
Full thickness skin loss with extensive destruction, necrosis, damage to muscle, bone, or supporting structures
Unstageable pressure ulcer
more than 50% necrotic tissue
proposed new stage pressure ulcer
deep tissue injury appears as a bruise
skin is intact
Primary intention
All tissues are closed with suture material
secondary intension
wound is left open to dry out and heal
3 phases
inflammatory proliferation and maturation
Inflammatory phase
1-4 days
bacteria killed
cellular debris removed
Proliferation phase
4-20 days
Deposition of connection tissue
Cross-linking of collagen
Maturation phase
21 days - 2 years
Strengthening and reorganization of collagen fibres
