Pressure ulcers must be assessed how?
at regular intervals using systematic parameters to evaluate wound healing, plan appropriate interventions, and evaluate progress
What should be included in assessing a pressure ulcer?
should include depth of tissue involvement (staging), type and approximate percentage of tissue in wound bed, wound dimensions, exduate description, and condition of surrounding skin
Accurate staging of an ulcer requires what? And what is the drawback?
knowledge of the skin layers, and a major drawback of a staging system is that an ulcer covered with necrotic tissue is covering the depth of the ulcer.
Pressure ulcer staging is used to what?
describe the pressure ulcer depth at the point of assessment
Stage 1 Pressure ulcer
is an observable pressure-related alteration of intact skin whose indications, as compared with an adjacent or opposite area on the body, may include changes in one or more of the following: skin temperature, tissue consistency, and/or sensation.
Stage 1 Pressure ucler continued
The ulcer appears as a defined area of persistent redness in lightly pigmented skin, whereas in darker skin tones the ulcer may appear with persistent red, blue, or purple hues. There are no open skin areas.
Stage 2 Pressure ulcer
Partial-thickness skin loss involving epidermis and/or dermis. The ulcer is superficial and presents clinically as an abrasion, blister, or shallow crater
Stage 3 Pressure ulcer
Full-thickness skin loss involving damage or necrosis of subcutaneous tissue that may extend down to, but not through, underlying fascia. The ulcer presents clinically as a deep crater with or without undermining of adjacent tissue.
Stage 4 Pressure ulcer
Full-thickness skin loss with extensive destruction, tissue necrosis, or damage to muscle, bone, or supporting structures. Undermining and sinus tracts also may be associated with this stage
Red, moist tissue is indication of what?
granulation tissue
slough
stringy substance attached to wound bed
eschar
necrotic tissue
Wound dimensions should include what?
consistent measurements of depth, length, and width
Exduate describes what?
the amount, color, consistency, and odor of wound drainage.
Excessive exduate can indicate what?
infection
Wound
is a disruption of normal anatomical structure and function that results from pathological processes beginning internally or externally to the involved organ
It is imperative for the nurse to know what about a wound?
all wounds are not created equal
Five questions that may be included in the nursing assessment of a wound's history
wound etiology, occurence, chronology, aggravating and alleviating factors, and associated symptoms
Wound classification systems describe what about a wound?
the status of skin integrity, cause of the wound, severity or extent of tissue injury or damage, cleanliness of the wound, or desriptive qualitites of the wound such as color
Wound Classification: Open
wound involving a break in skin or mucous membranes; Causes: Trauma by sharp object or blow (surgical incision, venipunture, gun shot wound)
Wound Classification: Status of Skin Integrity: Open; Implications for Healing
Break in skin exposes body to invasion by microorganisms. Loss of blood and body fluids through wound occurs. Functions of body parts is reduced
Wound Classification:Status of Skin Integrity: Closed; Causes
Wound involving no break in skin; Causes: Part of body being struck by blunt object; twisting, straining, or deceleration force against body (bone fracture, tear of visceral organ)
Wound Classification: Status of Skin Integrity: Closed; Implications for Healing
Wound may predispose person to internal hemorrhage. Function of affected body part is reduced.
Wound Classification: Status of Skin Integrity: Acute; Causes
Wound that proceeds through an orderly and timely reparative process that results in sustained restoration of anatomical and functional integrity. Causes: Trauma from a sharp object
Wound Classification: Status of Skin Integrity: Acute; Implications for Healing
Wounds are usually easily cleaned and repaired. Wound edges are clean and intact.
Wound Classification: Status of Skin Integrity: Chronic; Causes
Wound that fails to proceed through an orderly and timely process to produce anatomical and functional integrity. Causes: Ulcers exposed to friction, shear, moisture, or pressure
Wound Classification: Status of Skin Integrity: Chronic; Implications for Healing
Continued exposure to pressure, friction, shear, and moisture impedes wound healing. Wound tissue may be necrotic, and drainage may be present
Wound Classification: Cause: Intentional and Causes
Wound resulting from therapy; Causes: Surgical incision; introduction of needle into body part
Wound Classification: Cause: Intentional and Implications for Healing
Incision is usually performed under aseptic technique to minimize chance of infection. Wound edges are usually smooth and clean
Wound Classification: Cause: Unintentional and Causes
Wound that occurs unexpectedly. Causes: Traumatic injury (knife wound, burn)
Wound Classification: Cause: Unintentional and Implications for Healing
Wound occurs under unsterile conditions. Wound edges are often jagged.
Wound Classification: Severity of Injury: Superficial and Causes
Wound that involves only epidermal layer of skin. Causes: Result of friction applied to skin surface (abrasion, first-degree burn, shearing)
Wound Classification: Severity of Injury: Superficial and Implications for Healing
Break creates risk of infection. Wound does not involves underlying injury to tissues or organs. Blood supply to area is intact.
Wound Classification: Severity of Injury: Penetrating and Causes
Wound involving break in epidermal skin layer, as well as dermis and deeper tissues or organs: Causes: Foreign object or instrument entering deep into body tissues; usually unintentional (gunshot wound, stab wound)
Wound Classification: Severity of Injury: Penetrating and Implications for Healing
There is high risk of infection because foreign objects is contaiminated. Wound may cause internal and external hemorrhage; damage to organs causes temporary or permanent loss of function
Wound Classification: Severity of Injury: Perforating and Cause
Penetrating wound in which foreign objects enters and exists an internal organ. Causes: Foreign object or instrument entering deep into body tissues; usually unintentional (gunshot wound, stab wound)
Wound Classification: Severity of Injury: Perforating and Implications for Healing
There is high risk of infection. Nature of injury depends on organ perforated (lung, compromised oxygenation; major vessel, hemorrhage; intestine, contamination of abdominal cavity by feces).
Wound Classification: Cleanliness: Clean and Causes
Wound containing no pathogenic organisms. Causes: Closed surgical wound not entering GI, respiratory, genital, or uninfected urinary tract or oropharyngeal cavity.
Wound Classification: Cleanliness: Clean and Implications for Healing
There is low risk of infection
Wound Classification: Cleanliness: Clean-Contaminated and Causes
Wound made under aseptic conditions but involving body cavity that normally harbors microorganisms. Causes: Surgical wound entering GI, respiratory, genital, or urinary tract or oropharyngeal cavity under controlled conditions.
Wound Classification: Cleanliness: Clean-Contaminated and Implications for Healing
There is greater risk of infection than with clean wound
Wound Classification: Cleanliness: Contaminated and Causes
Wound existing under conditions in which presence of microorganisms is likely. Causes: Open, traumatic, accidental wounds; surgical wound in which break in asepsis occurred
Wound Classification: Cleanliness: Contaminated and Implications for Healing
Tissues are often not healthy and show inflammation. There is high risk of infection.
Wound Classification: Cleanliness: Infected and Causes
Bacterial organisms present in wound site, usually above 1,000,000 organisms per gram of tissue. Causes: Any wound that does not properly heal and grows organisms, old traumatic wound, surgical incision into area infected (e.g., ruptured bowel)
Wound Classification: Cleanliness: Infected and Implications for Healing
Wound presents signs of infection (inflammation, purulent drainage, skin separation).
Wound Classification: Cleanliness: Colonized and Causes
Wound containing microorganisms (usually multiple). Causes: Chronic wound (vascular stasis ulcer; pressure ulcer)
Wound Classification: Cleanliness: Colonized and Implications for Healing
Wound healing is slow, and high risk of infection exists.
Wound Classification: Descriptive Qualities: Laceration and Causes
Tearing of tissues with irregular wound edges. Causes: Severe traumatic injury (knife wound, industrial accident involving machinery, tissues cut by broken glass)
Wound Classification: Descriptive Qualities: Laceration and Implications for Healing
Wound is usually created by contaminated objects. Depth of wound determines other implications.
Wound Classification: Descriptive Qualities: Abrasion and Causes
Superficial wound involving scraping or rubbing of skin's surface. Causes: Wound often resulting from fall (skinned knee or elbow); wound also resulting from dermatological procedure for removing scar tissue.
Wound Classification: Descriptive Qualities: Abrasion and Implications for Healing
Wound is painful from exposure of superficial nerves; deeper tissues are not involved. There is risk of infection from exposure to contaminated surface.
Wound Classification: Descriptive Qualities: Contusion and Causes
Closed wound caused by a blow to body by blunt object; contusion or bruise characterized by swelling, discoloration, and pain. Causes: Bleeding in underlying tissues caused by blunt force against body part.
Wound Classification: Descriptive Qualities: Contusion and Implications for Healing
Wound is more severe if internal organ is contused. Wound may cause temporary loss of function of body part. Localized bleeding into tissues may form hematoma (collection of blood).
Three components involved in the healing process of a partial-thickness wound
inflammatory response, epithelial proliferation and migration, and reestablishment of the epidermal layers
Inflammatory response in partial-thickness wound
Is triggered by tissue trauma, causing redness and swelling to the area with a moderate amount of serous exduate. Response is generally limited to the first 24 hours after wounding. The epithelial cells begin to proliferate, providing new cells to replace the lost cells
Epithelial proliferation and migration in partial-thickness wound
starts at both the wound edges and the epidermal cells lining the epidermal appendages, allowing for quick resurfacing. A wound left open to air can resurface within 6 to 7 days, whereas a wound that is kept moist can resurface in 4 days.
Primary Intention
The skin edges are approximated, or closed, and the risk of infection is low. Healing occurs quickly; the inflammation typically subsides in less than 24 hours, and the wound is resurfaced between day 4 and 7.
Secondary Intention
A wound involving loss of tissue, such as a burn, pressure ulcer, or severe laceration, heals by secondary intention. The wound is left open until it becomes filled by scar tissue. It takes longer for a wound to heal by secondary intention, and thus the chance of infection is greater
Partial-thickness wounds
are shallow wounds involving loss of the epidermis (top layer) and possibly partial loss of the dermis. These wounds heal by regeneration because epidermis can regenerate. Example: the repair of a clean surgical wound or an abrasion.
Full-thickness wounds
extending into the dermis (involving both layers of tissue) heal by scar formation because deeper structures do not regenerate. Example: pressure ulcers
Dehiscence
is the partial or total separation of wound layers
Evisceration
protrusion of visceral organs through a wound opening
Fistula
is an abnormal passage between two organs or between and organ and the outside of the body.
Most fistulas form from what?
poor wound healing or as a complication of a disease, such as Crohn's disease.
What can prevent tissue layers from closing and allowing a fistula tract to form?
Trauma, infection, radiation exposure, and diseases such as cancer
Fistulas increase what?
the risk of infection and fluid and electrolytes imbalances from fluid loss
What does the nurse do when evisceration happens?
places sterile towels soaked in sterile saline over the extruding tissues to reduce chances of bacterial invasion and drying of the tissues. The client should be allowed NPO, observed for S/S of shock, and prepared for surgery

What is the cutoff score for onset of pressure ulcer risk?
In the general adult population, it is 18. For black adn Latino clients with darkly pigmented skin, a cutoff score of 18 has been suggested.
Factors That Impair Wound Healing
Age; Malnutrition; Obesity; Impaired Oxygenation; Smoking; Drugs; Diabetes; Radiation; Wound stress
Factors That Impair Wound Healing: Age
Aging alters all phases of wound healing. Vascular changes impair circulation to wound site. Reduced liver function alters synthesis of clotting factors. Inflammatory response is slowed. Formation of antibodies and lymphocytes is reduced. Collagen tissue is less pliable. Scare tissue is less elastic.
Factors That Impair Wound Healing: Age: Nursing Implications
Instruct client on safety precautions to avoid injuries. Be prepared to provide wound care for longer period. Teach support persons in home wound care techniques
Factors That Impair Wound Healing: Malnutrition
All phases of wound healing is impaired. Stress from burns or severe trauma increases nutritional requirement
Factors That Impair Wound Healing: Malnutrition: Nursing Implications
Provide balanced diet rich in protein, carbohydrates, lipids, vitamins A and C, and minerals (zinc, copper). Assess ability to chew foods; if problem noted, provide with liquid supplements. Provide adequate amounts of calories and fluid.
Factors That Impair Wound Healing: Obesity
Fatty tissue lacks adequate blood supply to resist bacterial infection and deliver nutrients and cellular elements for healing
Factors That Impair Wound Healing: Obesity: Nursing Implications
Observe obese client for signs of wound infection and evisceration.
Factors That Impair Wound Healing: Impaired Oxygenation
Low aterial oxygen tension alters synthesis of collagen and formation of epithelial cells. If local circulating blood flow is poor, tissues fail to receive needed oxygen. Decreased hemoglobin in blood (anemia) reduces arterial oxygen levels in capillaries and interferes with tissue repair
Factors That Impair Wound Healing: Impaired Oxygenation: Nursing Implications
Provide diet adequate in iron, Vitamin B12, and folic accid. Monitor hematocrit and hemoglobin levels of clients with wound
Factors That Impair Wound Healing: Smoking
Smoking reduces amount of functional hemoglobin in blood, thus decreasing tissue oxygenation. Smoking may increase platelet aggregation and cause hypercoagulability. Smoking interferes with normal cellular mechanisms that promote release of oxygen to tissue.
Factors That Impair Wound Healing: Smoking: Nursing Impications
Discourage client from smoking by explaining its effects on wound healing
Factors That Impair Wound Healing: Drugs
Steroids reduce inflammatory response and slow collagen synthesis. Antiinflammatory drugs suppress protein synthesis, wound contraction, epithelialization, and inflammation. Prolonged antibiotic use may increase risk of superinfection. Chemotherapeutic drugs can depress bone marrow function, lower number of leukocytes, and impair inflammatory response.
Factors That Impair Wound Healing: Drugs: Nursing Implications
Carefully observe clients reveiving these drugs because signs of inflammation may not be obvious. Vitamin A can counteract effects of steriods. Caution client to use only prescribed medications.
Factors That Impair Wound Healing: Diabetes
Chronic disease causes small blood vessel disease that impairs tissue perfusion. Diabetes causes hemoglobin to have greater affinity for oxygen, so it fails to release oxygen to tissues. Hyperglycemia alters ability of leukocytes to perform phagocytosis and also supports overgrowth of fungal and yeast infection.
Factors That Impair Wound Healing: Diabetes: Nursing Implications
Instruct diabetic clients to take preventive measures to avoid cuts or breaks in skin. Provide preventive foot care. Control blood sugar to reduce the physiological changes associated with diabetes.
Factors That Impair Wound Healing: Radiation
Fibrosis and vascular scarring eventually develop in irradicated skin layers. Tissue become fragile and poorly oxygenated.
Factors That Impair Wound Healing: Radiation: Nursing Implications
Closely observe clients who have surgery after radiation for wound complications
Factors That Impair Wound Healing: Wound Stress
Vomiting, abdominal distention, and respiratory effort may stress suture line and disrupt wound layer. Sudden, unexpected tension on incision inhibits formation of endothelial cell and collagen networks.
Factors That Impair Wound Healing: Wound Stress: Nursing Implications
Control nausea with ordered antemetics. Keep nasogastric tubes patent and draining to avoid accumulation of secretions. Instruct and help client to splint abdominal wound during coughing
Successful critical thinking requires what?
a synthesis of knowledge, experience, information gathered from clients, critical thinking attitudes, and intellectual and professional standards.
Clinical judgement requires what?
the nurse to anticipate the information necessary, analyze the data, and make decisions regarding client care.
When caring for a client who have impaired skin integrity and chronic wounds, the nurse must do what?
integrate knowledge from nursing and other disciplines, previous experiences, and information gathered from clients to understand the risk to skin integrity and wound healing
Knowledge of what enables the nurse to have a scientic basis of care?
normal musculoskeletal physiology, the pathogenesis of pressure ulcers, normal wound healing, and the pathophysiology of underlying diseases
