Chapter 32 Pressure Injuries Flashcards
Avoidable pressure injury
A pressure injury that develops from the improper use of the nursing process
Bony prominence
An area where the bone sticks out or projects from the flat surface of the body
Chairfast
Confined to a chair
Colonized
The presence of bacteria on the wound surface or in wound tissue; the person does not have signs and symptoms of an infection
Erythema
Redness of the skin
Eschar
Thick, leathery dead tissue that may be loose or adhered to the skin; it is often black or brown
Friction

Pressure injury
Localized damage to the skin and or underlying soft tissue usually over a bony prominence or related to a medical or other device. The injury can present as intact skin or an open ulcer and may be painful. Injury occurs as a result of intense and or prolonged pressure or pressure in combination with shear
Shear
When layers of the skin rub against each other; when the skin remains in place and underlying tissue move and stretch and tear underlying capillaries and blood vessels causing tissue damage
Slough
Dead tissue that is soft and often moist and appears white, yellow, green or tan; tissue may be firmly attached or loose and stringy
Unavoidable pressure injury
A pressure injury that occurs despite efforts to prevent one through proper use of the nursing process
Bedfast
Confined to a bed
Pressure injury stages
Stage 1 the skin is intact
Stage 2 partial -thickness skin loss (blister or shallow ulcer)
Stage 3 Full -Thickness skin loss (slough is dead tissue that is soft and often moist)
Stage 4 Full-Thickness skin and tissue loss with muscle, tendon, and bone exposures. (Eschar)
Unstageable Full-thickness tissue loss with the injury covered by slough and eschar
Deep Tissue Injury - purple or maroon localized area of discolored intact skin or blood filled blister.
