Pressure Ulcers, Wounds, and Wound Management - ATI - Chapter 55 Flashcards
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
_____ interfere with the body’s ability to respond to and prevent infection.
some medication
what medications interfere with the body’s ability to respond to and prevent infection.
anti-inflammatory
antineoplastic
_______ do not get the nutrition they need which provides energy and elements for wound healing.
malnourished clients
______ provides circulation that delivers nutrients for tissue repair and infection control can effect wound healing.
tissue perfusion
_____ effect wound healing because Hgb is essential for oxygen delivery to healing tissues.
low Hgb levels
______ can effect wound healing because fatty tissue lacks blood supply.
obesity
______ such as diabetes mellitus and cardiovascular disorders, place additional stress on the body’s healing mechanisms which effect wound healing.
chronic diseases
_____ such as from vomiting or coughing, puts pressure on the suture line and disrupts the wound healing process.
wound stress
Wounds impair ____.
skin integrity
_____ is a localized protective response to injury or destruction of tissue.
inflammation
Wounds heal by various processes and in ______.
stages
Wound _____ result from the invasion of pathogenic micro-organisms.
infections.
Principles of wound care include assessment, _____, and protection.
cleansing
During assessment/data collection note the ______ of the open wounds.
color
A ____ wound means there is healthy regeneration of tissue.
red
A ____ colored wound means there is a presence of purulent drainage and slough.
yellow
A ____ wound means there is a presence of eschar that hinders healing and requires removal.
black
Assess the length, width, and ____ of wounds, and any undermining, sinus tracts or ______, and redness or swelling.
depth
tunnels
When assessing wounds use a ____ with 12:00 toward the client’s head to document the location of sinus tracts.
clock face
Use the RYB color guide for wound care:
Red = cover
Yellow = ____
Black = _____
Yellow = clean
Black = debride, removal of necrotic tissue
With ___ wounds skin edges should be well-approximated.
closed wounds
________ is a result of the healing process and occurs during the inflammatory and proliferative phases of healing.
drainage (exudate)
Note the amount, odor, and _____ and color of drainage from a drain or on a dressing.
consistency
Not the _____ of the surrounding skin.
integrity
With each cleansing, observe the skin around a drain for ______ and breakdown.
irritation
For accurate measurement of drainage, ____ the dressing.
weigh
Note and document the _____ of dressings and frequency of dressing changes.
number
The portion of the blood (serum) that is watery and clear or slightly yellow in appearance (i.e. fluid blisters) is called _____
serous drainage
_____ drainage contains serum and red blood cells. It is thick and appears reddish. Brighter drainage indicates fresh bleeding; darker drainage indicates older _____.
sanguineous drainage
bleeding drainage
_______ drainage contains both serum and blood. It is watery and appears blood-streaked or blood tinged.
serosanguineous drainage
____ drainage is the result of inflection.
purulent
______ drainage is a mixed drainage of pus and blood (i.e. newly infected wound)
purosanguineous
____ drainage is thick and contains white blood cells, tissue debris, and bacteria. It may have a foul odor, and its color such as yellow, tan, brown reflects the type of organism present (green for Pseuduomonoas aeroguinosa infection).
purulent
Types of wound closures (3)
staples
sutures
wound-closure strips
Note the location, quality, intensity, timing, setting, associated manifestations, and aggravating/relieving factors associated with any ____.
