Ch 32 Skin integrity and wound care Flashcards
Abscess
Collection of infected fluid that has not drained
Bandage
A piece of gauze or other material used to cover a wound
Biofilm
A thick grouping of microorganisms
Debridement
Cleaning away devitalized tissue and foreign matter from a wound
Dehiscence
Separation of the layers of a surgical wound; may be partial, superficial, or a complete disruption of the surgical wound
Dermis
Layer of skin below the Epi-dermis
Desiccation
Dehydration; the process of being rendered free for moisture
Dressing
Protective covering placed over a wound
Epidermidis
Superficial layer of the skin
Epithelialization
Stage of wound healing in which the epithelial cells form across the surface of the wound; tissue color ranges from the color of ground glass to pink
Erythema
Redness of the skin
Eschar
Thick, leather scabbard dry crust that is necrotic and must be removed for adequate healing to occur
Evisceration
Protrusion of viscera through an incision
Exudate
Fluid that accumulates in a wound; may contain serum, cellular debris, bacteria, and white blood cells
Fistula
And abnormal passage from the internal organ to the skin or from one internal organ to another
Friction
 occurs when two Surfaces rub against each other; the resulting injury resembles an abrasion and can also damage superficial blood vessels directly under the skin
Granulation tissue
New tissue that is pink/red in color and composed of fiber blast and small blood vessels that fill an open wound when it starts to heal
Hematoma
Localized mass of unusually clotted blood
Ischemia
Deficiency of blood in a particular area
Maceration
Softening through liquid; overhydration
Necrosis
Death of cells and tissue
Negative pressure wound therapy (NPWT)
Activity that promotes wound healing and wound closure through the application of uniform negative pressure on the wound bed, reduction in bacteria in the wound, and removal of excess wound fluid
Pressure injury
- Localized damage to the skin and the underlying tissue that usually occurs over bony prominence or is related to the use of a medical or other device
- Any lesion caused by unrelieved pressure that results in damage to underlying tissue; formally known as pressure ulcer
Purulent drainage
Composed of white blood cells, liquefied the tissue debris, and both dead and live bacteria
Sanguineous Drainage
Containing or mixed with blood
Scar
Connective tissue that fills a wound area
serosanguineous drainage
Mixture of serum and Red blood cells
Serous drainage
Composed of clear, serius portion of the blood and from serous membranes
Shear
Force created when layers of tissue move on one another
Subcutaneous tissue
Underlying layer that anchors the skin layers to the underlying tissues of the body
Wound
 injury that results in a disruption in the normal continuity of a body tissue
Nodule
Elevated, firm, circumcised lesion; deeper than dermis than a papule; 1 to 2 cm in diameter (lipoma)
Papule
An elevated, firm circumcised area less than 1 cm in diameter; (wart, elevated mole)
Patch
A flat, non-palpable, irregularly shaped Macule more than 1 cm in diameter (Port wine stain)
Plaque
Elevated, firm, and rough lesion with flat top surface greater than 1 cm in diameter; psoriasis
Pustule
Elevated, superficial lesion; similar to a vesicle but filled with purulent fluid; (acne)
Bulla
Vesicle greater than 1 cm in diameter; blister
Vesicle
Elevated, Circumscribed, superficial, not into dermis; filled with serous fluid; less than 1 cm in diameter; chicken pocks
Wheal
Elevated irregularly shaped area of cutaneous edema; solid, temporary; variable diameter; insect bite
Lichenification
Rough, Second epidermis is secondary to persistent rubbing, itching, or skin irritation; often involves the flexor surface of the extremity; chronic dermatitis
Telangiectasia
Fine, irregular red lines produced by capillary dilation; found in rosacea
Macule
A flat, circumcised area that is a change in the color of the skin; less than 1 cm in diameter; freckles, flat mall
