happens when one tissue layer slides over another. Lift clients with draw sheet. DO NOT slide client up the bed. GOOD BODY MECHANICS. Shear force or force created when the skin of a pt stays in one place as the deep fascia and skeletal muscle slide down with gravity. This can also cause the pinching off of blood vessels which may lead to ischemia and tissue necrosis. Bedridden patients and wheelchair users in half-sitting position are very vulnerable for shear wounds.

Systematic skin assessment at least once a day. Clean skin when soiled or at routine intervals or when client needs or preference dictates. Avoid hot water and apply as little force and friction as possible. Keep hydrated ~ low humidity and exposure to cold and dry skin is more susceptible to mechanical trauma. Use moisturizers.Provide sufficient dietary intake of protein and calories. Maintain client's current level of activity mobility

Back 14

Skin is a common site for malignancy. Skin cancer is the most common form of all cancers. Nonmelanoma Skin Cancer- do not arise from melanin producing cells. Most caused by sun- UVR. May alter DNA or suppress T-Cell and B-Cell immunity. Most common malignant growth found in fair-skinned people. Skin pigmentation affects the development of nonmelanoma skin cancer. The more melanin in the skin (darker) the more protection from damaging UV rays. 2 types of Nonmelanoma Skin cancer1. Basal Cell Carcinoma- most common2. Squamous Cell carcinoma

Hint 14

Front 15

Basal Cell Carcinoma

Back 15

Begins in the basal cell layer of the epidermis usually on sun-exposed areas. Slow-growing and rarely metastasize but can invade nearby areas. Can recur in same location after tx. Starts as smooth itchy pimple but as they grow, becomes shiny and pearly white or pink/skin colored

Squamous Cell Carcinoma

Back 74

Debridement- the process of removing dead tissue from a wound. Eschar is a hard crust that forms over the burn wound. Burn wounds must be cleaned and debrided of nerotic tissue and blisters to promote healing and prevent prolonged inflammation. Usually occurs 1 week after the burn. The wound is cleansed with an antimicrobial soap

such as Hibiclens. Dial or Shur-Clens for the face due to toxicity to the eyes with Hibiclens. Hair is shaved. IV narcotics are administered before debridement to control pain.

What happens to the fluids/electrolytes following a burn during the different stages?

Back 82

(see powerpoints for burn pathophysiology

Hint 82

Involves all systems of body.) During the first 48 hours after a burn--capillary permeability is increasing allowing fluids to shift from plasma to the interstitial spaces. The fluid is high in sodium causing a decrease in serum sodium or hyponatremia (135-145 mEq/L). Potassium leaks from the cells into the plasma  hyperkalemia (3.5-5.0 mEq/L)Fluid loss via evaporation occurs and must be replaced. Larger the burn

Front 83

Urine output should be used as a measure of renal perfusion and to assess fluid balance.

Back 83

In adults a urine output of 30-50 mL/hr and a child 0.5/kg/h should be maintained.

Pts with significant burns should have a FOLEY CATHETER inserted in order to monitor urine output closely with a UROMETER.

GRAFTING

Autografting: Permanent skin coverage of the wound. Performed early. Skin is removed from a donor site and applied to the burn wound from the client.
