Pressure Ulcers, Wounds, and Wound Management - ATI - Chapter 55 Flashcards
(169 cards)
Wounds are a result of injury to the ____.
skin.
Although there are many different methods and degrees of injury, the ______ of healing are essentially the same for most wounds.
basic phases
A pressure ulcer (formerly called a _______) is a specific type of tissue injury from unrelieved pressure or friction over bony prominences that results in ischemia and damage to the underlying tissue.
decubitus ulcer
The stages of wound healing
Inflammatory Stage
Proliferative Stage
Maturation or remodeling Stage
Inflammatory stage begins with the injury and lasts _____ days.
3-6 days
Controlling bleeding with vasoconstriction and retraction of blood vessels, and with ______ in the inflammatory stage.
clot formation
During the ______ stage oxygen, white blood cells, and nutrients are delivered to the area via the blood supply.
inflammatory stage
____ occurs along with fibrin formation during the inflammatory stage.
hemostasis
____ engulf microorgansims and cellular debris (phagocytosis) during the inflammatory stage.
macrophages
The ____ stage lasts the next 3 to 24 days in the wound healing process.
proliferative
During the proliferative stage lost tissue is replaced with ______ or ______ tissue or collagen.
connective or granulated
During the proliferative stage the wound’s edges are ____.
contracting
Resurfacing of new _______ occurs during the proliferative stage.
epithelial cells
____ stage occurs after day 21 and involves the strengthening of the collagen scar and the restoration of a more normal appearance.
maturation or remodeling stage
It can take more than a year to complete, depending on the extent of the original wound during the _____ stage.
maturation or remodeling stage
The types of the healing processes
primary intention
secondary intention
tertiary intention
Little or no tissue loss Edges approximated, as with a surgical incision Heals rapidly Low risk of infection No or minimal scarring
i.e. closed surgical incision with staples or sutures or liquid glue to seal laceration.
primary intention
Loss of tissue Wound edges widely separated, unapproximated (pressure ulcers, open burn areas) Longer healing time Increase for risk of infection Scarring Heals by granulation
i.e. pressure ulcer left open to heal
secondary intention
Widely separated Deep Spontaneous opening of a previously closed wound Closure of wound occurs when free of infection Risk of infection Extensive drainage and tissue debris Closed later Long healing time
i.e. Abdominal wound initially left open until infection is resolved and then closed.
Tertiary intention
Factors affecting wound healing
Age Overall Wellness Decreased leukocyte count Some medications malnourished clients tissue perfusion low Hgb levels obesity chronic diseases smoking wound stress
Increased ___ delays healing.
age
A wound in a young, healthy client will heal faster than a wound in an older adult who has a chronic illness due to the _______ risk factor that affects wound healing.
overall wellness
_____ delays wound healing because the immune system function is to fight infection by destroying invading pathogens.
decreased leukocyte count
Age effects wound healing because of the following (8)
loss of skin turgor skin fragility decrease in peripheral circulation and oxygenation slower tissue regeneration decrease in absorption of nutrients decrease in collagen impaired immune system function dehydration due to decreased thirst sensation
