NC chapters 22, 23, 33, 39

an injury in which a portion of the body is denuded of epidermis by scraping or rubbing

abrasion

referring to fat tissue

adipose

an injury in which part of the body is completely severed

amputation

an injury that leaves a piece of skin or other tissue partially or completely torn away from the body

avulsion

material used to secure a dressing in place

bandage

secreted proteins that cause cells to migrate into an area

chemotactic factors

an injury in which damage occurs beneath the skin or mucus membrane but the surface remains intact

closed wound

a protein that gives tensile strength to the connective tissues of the body

collagen

a condition that develops when hemorrhage and swelling result in increased pressure within soft tissues, and compromises the circulation to the nerves and muscles within the involved compartment, possibly resulting in tissue necrosis

compartment syndrome

the presence or the reasonable anticipated presence of blood or other potentially infectious materials, such as microorganisms, on an item or surface

contaminated

a bruise; an injury that causes bleeding beneath the skin but does not break the skin

contusion

an injury in which the body or part of the body is crushed, preventing tissue function and, possibly, resulting in permanent tissue damage

crush injury

significant metabolic derangement that can lead to renal failure and death. it develops when crushed extremities or other body parts remain trapped for prolonged periods

crush syndrome

a dense layer of fibrous tissue below the subcutaneous tissue; composed of tough bands of tissue that ensheath muscles and other internal structures

deep fascia

a traumatic injury that results in the soft tissue of the hand being drawn downwards like a glove being removed

degloving

to release granules of a substance into the surrounding tissue

degranulate

the inner layer of skin, containing hair follicle roots, glands, immune cells, blood vessels, and nerves

dermis

material used to directly cover a wound

dressing

localized bruising or blood collection within or under the skin

ecchymosis

a protein that gives the skin its elasticity

elastin

the outermost layer of the skin

epidermis

the formation of fresh epithelial tissue to heal a wound

epithelialization

reddening of the skin

erythema

a surgical procedure that cuts away fascia to relieve pressure

called fasciotomy.

localized death and decomposition of body tissue, resulting from either obstructed circulation or bacterial infection

gangrene

the first step in the formation of urine; the rate is calculated to determine renal function

This process is known as glomerular filtration.

cells that contain granules

granulocytes

material between cells

ground substance

a localized collection of blood in the soft tissues as a result of injury or a broken blood vessel

hematoma

a tendency to constancy or stability in the body’s internal environment; processes that balance the supply and demand of the body’s needs

homeostasis

a elevated blood serum potassium level

hyperkalemia

an abnormal scar with excess collagen that does not extend over the wound margins

hypertrophic scar

an object that has caused a puncture wound and remains embedded in the wound

impaled object

a wound usually made deliberately, as in surgery a clean cut as opposed to a laceration

incision

the skin
