Chapter 26 Flashcards
Loss or damage of the superficial layer of skin as a result of a body part rubbing or scraping across a rough or hard surface
Abrasion
An injury in which part of the body is completely severed
Amputation
An injury in which soft tissue is torn completely loose or is hanging as a flap
Avulsion
Injuries in which soft-tissue damage occurs as a result of thermal heat,frictional heat, toxic chemicals, electricity, or nuclear radiation
Burns
Injuries in which damage occurs beneath the skin or mucous membrane but the surface of the skin remains intact
Closer injuries
Swelling in a confined space that produces dangerous pressure; may cut off blood flow or damage sensitive tissue
Compartment syndrome
A burn caused by direct contact with a hot object
Contact burn
The presence of infective organisms or foreign bodies such as dirt, gravel, or metal
Contamination
A bruise from an injury that cause we bleeding beneath the skin without breaking the skin
Contusion
Significant metabolic derangement that develops when crushed extremities or body parts remain trapped for prolonged periods. This can lead to renal failure and death
Crush syndrome
An injury that occurs when a great amount of force is applied to the body
Crushing injury
The inner layer of the skin, containing hair follicles, sweat glands, nerve endings, and blood vessels
Dermis
Discoloration associated with a closed wound; signifies bleeding
Ecchymosis
The outer layer of skin that acts as a watertight protective covering
Epidermis
The displacement of organs outside the body
Evisceration
A serious behavioral condition in which a person exhibits agitated behavior combined with disorientation, hallucinations, or delusions; also called agitated delirium or exhaustive mania
Excited delirium
The fiberlike connective tissue that covers arteries, veins, tendons, and ligaments
Fascia
A burn caused by an open flame
Flame burn
A burn caused by exposure to very intense heat, such as in an explosion
Flash burn
Burns that affect all skin layers and may affect the subcutaneous layers, muscle, bind, and internal organs, leaving the area dry, leathery, and white, dark brown, or charred
Full-thickness (third degree) burn
Blood collect e within the body’s tissues or in a body cavity
Hematoma
Objects that penetrate the skin but remain in place
Impaled objects
A sharp, smooth cut in the skin
Incision
A deep, jagger cut in the skin
Laceration
The lining of body cavities and passages that are in direct contact with the outside environment
Mucous membranes
Dressings made or petroleum (Vaseline) gauze, aluminum foil, or plastic that prevents air and liquids from entering or exiting a wound
Occlusive dressings
Injuries in which there is a break in the surface of the skin or the mucous membrane, exposing deeper tissue to potential contamination
Open injuries
Burns that affect the epidermis and some portion of the dermis but not the subcutaneous tissue, characterized by blisters and skin that is white to red, moist, and mottled
Partial-thickness ( second-degree) burns
An injuring resulting from a sharp, piercing object
Penetrating wound
Infected with rabies
Rabid
A system that assigns percentages to sections of the body, allowing calculations of the amount of skin surface involved in the burn area
Rule or nines
A burn caused by hot liquids
Scald burn
A burn caused by exposure to hot steam
Steam burn
Burns that affect only the epidermis, characterized by skin that is red but not blistered or actually burned through
Superficial (first -degree) burns
Burns caused by heat
Thermal burn
what are the two principle layers of skin?
epidermis and dermis
in what layer contain pigment granules(deeper cells)
germinal layer(base of epidermis)
what contains the structure that give the skin its characteristic appearance: hair follicles, sweat glands, and sebaceous glands
the dermis, it lies below the germinal cells of the epidermis
what is the oily material that waterproofs the skin
sebum
the mouth, nose,anus, and vagina are lined with what?
mucous membranes
what is the skins several functions
it protects the body by keeping pathogens out and fluids in, and it helps regulate body temp
what is the major organ for regulating temp
the skin
a tough, fibrous protein found in scar tissue, hair, bones and connective tissue
collagen
