| Question | Answer |
|---|---|
| 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 |
| WEAR GLOVES WHEN TOUCHING | lesions |
| 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 |
