What are primary vs secondary lesions?
Primary lesions: Anything that is not normal of the skin. (mole, bruise)
Secondary lesions: A lesion that results from a lesion (scratching, crusting)
Pressure ulcers
What are they?
Why do they commonly result?
- Sores that result from prolonged, unrelieved pressure
- Bone (tailbone, heel) presses on b.v. and causes decreased blood supply and necrosis
What are these things that can cause pressure ulcers:
- Shearing
- Friction
- Shearing: Two surfaces move against each other (patient moves against mattress)
- Friction: Two surfaces rubbing against one another (both surfaces move: sheets)
What are these stages of pressure ulcers:
- Stage 1
- Stage 2
Stage 1: Non-blanchable erythema intact skin
Stage 2: partial thinckness Skin loss involving epidermis/dermis
What are these stages of pressure ulcers:
- Stage 3
- Stage 4
- Stage 3= Full thickness skin loss with loss of fatty tissue
- Stage 4: Full thickness skin loss with damage to muscle/ligaments/bones (appears silvery)
What are these types of pressure ulcers:
- Suspected deep tissue injury
- Unstageable:
Deep tissue: Discolored intact skin (purple/maroon) (feels mushy)
Unstageable: Full tissue loss but covered by slough or eschar
What are the preventative techniques for pressure ulcers:
- Skin assessment (every shift)
- Frequent Reposition/pressure reduction
- Elimination of moisture
What are some risk factors of pressure ulcers:
- Malnutrition (lack of protein)
- Previous ulcers
- lack of movement
What are these terms:
- Comedome
- Burrow
Comedome: Oil gland that gets plugged with dirt/debris
Burrow: Parasite that burrows through skin
What are these terms:
- Petechiae
- Purpura
- Telangiectasia
Petechiae: Little red pinpoints from rupture capillary
Purpura: Large purble/blue skin from ruptured capillary
Telangiectasia: Dilated superficial blood vessels
Pruritus
What is it/what is it caused by?
Pruritus: Itching caused by mediators like histamine
Eczema:
What are these types of dermatitis:
What are the treatments
Inflammation/thickening of skin that cause bumps/pruritus
Treatment: Antihistamine
What is alergic contact dermatitis:
Type 4 allergic reaction (T-cell mediated/delayed) that causes dermatitis from contact with allergen
(poison ivy)
- What is irritant contact dermatitis?
- What is Atopic Dermatitis?
Irritant contact
Innate immune response from skin irritation (not an allergy)
Atopic Dermatitis:
Type 1 hypersensitivity (IgE antibodies) from asthma, allergies, etc…
What is Stasis Dermatitis?
What are the treatments?
Inflammation of skin from venous stasis/edema
Treatments:
- Elevate legs
- Avoid standing still for long periods
What is seborrheic dermatitis?
Inflammation of primarily scalp/face (can be anywhere)
- Scaly, dry flaky skin (dandruff or cradle cap)
What is Psoriasis?
Chronic skin disorder that causes thick, silvery scales
- Skin growth rate is higher than falloff rate
What is the difference in eczema and psoriasis?
Eczema
is thought to be environmental
Inflamed skin
Psoriasis
Autoimmune
Buildup of skin
