Skin. FUND

246 Quiz 2

largest organ of the body skin
skin is composed of the epidermal and dermal layers
produce sebum that is usually released in hair follicles Oil or Sebaceous Glands
The Major Functions of the Cutaneous Glands EVERYTHING!!! slide 8
thin fiber compound of dead keratinized cells hair
thin plates of keratinized epidermal cells that cover the distal ends of fingers and toes nails
when an individual has more melanin deposited in the skin, the color red becomes purple
What to Ask? (OLD CART) Onset, location, duration, character, associated symptoms, relieving factors, treatments
New skin cells moving rapidly to the skin surface that build up and form thick patches, plaques, ranging in size. Most often appear on the knees, elbows, scalp, hands, feet, or lower back. Adults and children Psoriasis
Seborrhea dandruff
Papulosquamous eczema
autoimmune destruction of melanocytes. vitiligo
depletion of melanosomes in keratinocytes Pityriasis versicolor
Soft tissue compression between a bony prominence and an external surface pressure ulcer
is tension that stretches skin during turning/moving in bed. Shearing
Results in a decrease of blood flow (through compression) in a localized area. Shearing
Sacrum, heels, elbows, ankle, hips, ischial tubererosities Shearing
Bone tissue is site of primary injury Shearing
Skin intact with non-blanchable redness to a localized area, Observable pressure. Redness on intact skin. Cell death can be prevented if action is taken. stage 1
Partial thickness loss of dermis presenting as a shallow open ulcer with a red pink wound bed, without slough. May also present as an intact or open/ruptured serum-filled blister stage 2
Full thickness tissue loss. Subcutaneous fat may be visible but bone, tendon or muscle are not exposed. Slough may be present but does not obscure the depth of tissue loss. May include undermining and tunneling stage 3
a disruption of normal integrity of skin and tissues wound
Shallow, involving loss of epidermis , Possible loss of dermis, Sweat glands and hair follicles intact, Heal by regeneration Partial Thickness Wounds
Extend into the dermis, May extend to subcutaneous tissue, muscle, bone, Heal by filling in wound bed with granulation tissue, Wound healing is prolonged, Scar formation occurs, Deeper structures do not regenerate Full Thickness Wounds
Growth of small vessels and connective tissue to fill full-thickness wound, Red, moist, shiny, viable tissue—velvet-like appearance , Indicates healing Granulation tissue
Stringy substance attached to wound bed, Must be removed before wound can heal Slough
Necrotic tissue, Must be removed before wound can heal Eschar
Removal of non-viable, necrotic tissue, Removes source of infection, Enables visualization of wound bed, Provides a clean base for healing Debridement
skin edges approximate or are close together, risk of infection slight. clean surgical incision (little or no tissue loss) primary intention
edges are not approximated, increased risk for infection and loss of tissue function, Laceration or a chronic wound such as a pressure ulcer Secondary Intention
Wound is kept open for several days. The superficial wound edges are then approximated, and the center of the wound heals by granulation tissue formation. Tertiary Intention
Purposes of Dressings Protect a wound from microorganism contamination
Dry or moist gauze
protects the wound from surface contamination Hydrocolloid
maintains a moist surface to support healing Hydrogel
uses negative pressure to support healing Wound vacuum assisted closure (V.A.C.)
create pressure, immobilize and/or support a wound, reduce or prevent edema, secure a splint, secure dressings bandages and binders
Assess the skin and skin integrity., Assess the patient’s response to stimuli., Assess the equipment being used., Identify any contraindications Assessment for temperature tolerance
Contraindications to heat active bleeding
Vasoconstriction, Local anesthesia, Reduced cell metabolism, Increased blood viscosity, Decreased muscle tension Cold
Vasodilation, Reduced blood viscosity, Reduced muscle tension, Increased tissue metabolism, Increased capillary permeability Heat
Contraindications to cold edema, impaired circulation, shivering, decreased sensation, level of conscious
Scalp lesions//Tinea capitis (ringworm) treatment Oral griseofulvin (Lamisil) until 2 wks beyond clinical resolution
T. Capitis//Tinea capitis w/kerion treatment with po steroids
pruritic eczematous rash (reaction to fungus) treatment Rx with lubricants and topical steroids and continue on griseofulvin for a complete course
