Tissue Integrity Flashcards
The outer most layer of the skin, made of squamous epithelial cells, which provides a barrier against the external environment.
Epidermis
Cells formed in the basal layer of the skin that function to protect the skin from the external environment.
Keratinocytes
A pigment that determines he color of the hair, skin, and eyes.
Melanin
Receptor cells in the epidermis that are specialized for detection of light touch.
Merkel cells
Cells found in the epidermis that play a role in cutaneous immune system reactions.
Langerhans cells
The layer under the epidermis that is composed mainly of connective tissue and provides strength and flexibility of the skin.
Dermis
An irritation of the epidermis caused by moisture.
Maceration
A red skin irritation that develops when the skin is exposed to irritants such as feces, urine, stoma effluent, and wound exudates.
Dermatitis
Loss of the top skin layer caused by mechanical forces. The severity of a skin tear is defined by the depth of the skin layer loss.
Skin tears
At-risk vulnerable skin
Skin frailty
Localized damage to the skin and/or the soft underlying tissue, which can be caused by prolong contact with a firm surface that interferes with circulation to the area.
Pressure injuries
An infection of the superficial layers of skin.
Cellulitis
redness of the skin due ot dilation of blood vessels.
Erythema
An area of a reddened skin that temporarily turns white or pale when light pressure is applied. The skin then reddens when pressure is relieved.
Blanchable eryhema
Redness of the skin that does not go away when pressure is applied and indicates structural damage has occurred in the small vessels supplying blood to the underlying skin and tissues.
Nonblanchable erythema
Any tearing of the skin, usually caused by blunt or sharp objects
Lacerations
Fluid secreted by the body during the inflammatory stage of healing and is made of plasma.
Exudate
Moisture-associated skin damage
A form of dermatitis; a skin irritation that forms when the skin is exposed to irritants like feces, urine, stoma content, and wound exudates.
Thin, watery wound drainage.
Serous
Thin watery wound drainage mixed with blood.
Serosanguineous
Bloody drainage.
Sanguineous
Blood/yellow wound drainage.
Purulent
A narrow channel or passage way extending it in any direction from the base of the wound.
Tunneling.
A force parallel to the surface of the skin.
Shearing
