Select all that apply. a. Hemostasis occurs immediately after the initial injury. b. A liquid called exudate is formed during the proliferation phase. c. White blood cells move to the wound in the inflammatory phase. d. Granulation tissue forms in the inflammatory phase. e. During the inflammatory phase, the patient has generalized body response. f. A scar forms during the proliferation phase.
a, c, e Hemostasis occurs immediately after the initial injury. White blood cells move to the wound in the inflammatory phase. During the inflammatory phase, the patient has generalized body response. Hemostasis occurs immediately after the initial injury and exudate occurs in this phase due to the leaking out of plasma and blood components into the injured area. White blood cells, predominantly leukocytes and macrophages, move to the wound in the inflammatory phase to ingest bacteria and cellular debris. During the inflammatory phase, the patient has a generalized body response, including a mildly elevated temperature, leukocytosis (increased number of white blood cells in the blood), and generalized malaise. New tissue, called granulation tissue, forms the foundation for scar tissue development in the proliferation phase. New collagen continues to be deposited in the maturation phase, which forms a scar.
What is the process of excessive bleeding?
results in large clots which increase the amount of space that must be filled during healing Interferes with oxygen diffusion to the tissue Accumulated blood is a place for bacteria to grow Promotes infection
Debridement

Insert a calibrated probe gently into the wound and mark the point that is even with the surrounding skin surface with a marker.
a. Moisten a sterile, flexible applicator with saline and insert it gently into the wound at a 90-degree angle with the tip down. To measure the depth of a wound, the nurse should perform hand hygiene and put on gloves; moisten a sterile, flexible applicator with saline and insert it gently into the wound at a 90-degree angle with the tip down; mark the point on the swab that is even with the surrounding skin surface, or grasp the applicator with the thumb and forefinger at the point corresponding to the wound's margin; and remove the swab and measure the depth with a ruler.
Thirty-six hours after having surgery, a patient has a slightly elevated body temperature and generalized malaise, as well as pain and redness at the surgical site. Which intervention is most important to include in this patient's nursing care plan? a. Document the findings and continue to monitor the patient. b. Administer antipyretics, as ordered. c. Increase the frequency of assessment to every hour and notify the patient's primary care provider. d. Increase the frequency of wound care and contact the primary care provider for an antibiotic order.
a. Document the findings and continue to monitor the patient. The assessment findings are normal for this stage of healing following surgery. The patient is in the inflammatory phase of the healing process, which involves a response by the immune system. This acute inflammation is characterized by pain, heat, redness, and swelling at the site of the injury (surgery, in this case). The patient also has a generalized body response, including a mildly elevated temperature, leukocytosis, and generalized malaise.
What is a fistula? why created?
abnormal passage from an internal organ or vessel to the outside of the body Or from one internal organ or vessel to another Created purposely: arteriovenous fistula for kidney dialysis Usually result of an infection that as turned into an abscess (collection of infected fluid that has not drained) applies pressure to surrounding tissues = unnatural passage
Wound
an injury, usually involving division of tissue or rupture of the integument or mucous membrane, due to external violence

The patient's age of 86 years. c. Patient reports inability to control urine. d. A scheduled hip arthroplasty e. Lab findings include BUN 12 (elderly normal 8-23 mg/dL) and creatinine 0.9 (adult female normal 0.61-1 mg/dL). f. Patient reports increased pain in right hip when repositioning in bed or chair.
b, c, d, f The patient's age of 86 years. Patient reports inability to control urine. A scheduled hip arthroplasty Patient reports increased pain in right hip when repositioning in bed or chair. Pressure, friction, and shear, as well as other factors, usually combine to contribute to pressure ulcer development. The skin of older adults is more susceptible to injury; incontinence contributes to prolonged moisture on the skin, as well as negative effects related to urine in contact with skin; hip surgery involves decreased mobility during the postoperative period, as well as pain with movement, contributing to immobility; and increased pain in the hip may contribute to increased immobility. All these factors are related to an increased risk for pressure ulcer development. Apathy, confusion, and/or altered mental status are risk factors for pressure ulcer development. Dehydration (indicated by an elevated BUN and creatinine) is a risk for pressure ulcer development.
What is the process of infection?
bacteria in the wound increases stress on the body requiring large amounts of energy to fight the microorganisms Toxins produced by bacteria and released when bacteria die interfere with healing and cause cell death.

Decreased effectiveness of antibiotics against the bacteria d. Impaired skin integrity due to overhydration of the cells of the wound e. Delayed healing due to cells dehydrating and dying f. Decreased effectiveness of the patient's normal immune process
c, f Decreased effectiveness of antibiotics against the bacteria Decreased effectiveness of the patient's normal immune process Wound biofilms are the result of wound bacteria growing in clumps, imbedded in a thick, self-made, protective, slimy barrier of sugars and proteins. This barrier contributes to decreased effectiveness of antibiotics against the bacteria (antibiotic resistance) and decreases the effectiveness of the normal immune response by the patient (Beitz, 2012). Necrosis (dead tissue) in the wound delays healing. Maceration or overhydration of cells related to urinary and fecal incontinence can lead to impaired skin integrity. Desiccation is the process of drying up, in which cells dehydrate and die in a dry environment.
A nurse is explaining to a patient the anticipated effect of the application of cold to an injured area. What response indicates that the patient understands the explanation? a. "I can expect to have more discomfort in the area where the cold is applied." b. "I should expect more drainage from the incision after the ice has been in place." c. "I should see less swelling and redness with the cold treatment." d. "My incision may bleed more when the ice is first applied."
c. "I should see less swelling and redness with the cold treatment." The local application of cold constricts peripheral blood vessels, reduces muscle spasms, and promotes comfort. Cold reduces blood flow to tissues, decreases the local release of pain-producing substances, decreases metabolic needs, and capillary permeability. The resulting effects include decreased edema, coagulation of blood at the wound site, promotion of comfort, decreased drainage from wound, and decreased bleeding.
A nurse is providing patient teaching regarding the use of negative-pressure wound therapy. Which explanation provides the most accurate information to the patient? a. The therapy is used to collect excess blood loss and prevent the formation of a scab. b. The therapy will prevent infection, ensuring that the wound heals with less scar tissue. c. The therapy provides a moist environment and stimulates blood flow to the wound. d. The therapy irrigates the wound to keep it free from debris and excess wound fluid.
c. The therapy provides a moist environment and stimulates blood flow to the wound. Negative-pressure wound therapy (or topical negative pressure [TNP]) promotes wound healing and wound closure through the application of uniform negative pressure on the wound bed, reduction in bacteria in the wound, and the removal of excess wound fluid, while providing a moist wound healing environment. The negative pressure results in mechanical tension on the wound tissues, stimulating cell proliferation, blood flow to wounds, and the growth of new blood vessels. It is used to treat a variety of acute or chronic wounds, wounds with heavy drainage, wounds failing to heal, or healing slowly.
A patient, age 16, was in an automobile accident and received a wound across her nose and cheek. After surgery to repair the wound, the patient says, "I am so ugly now." Based on this statement, what nursing diagnosis would be most appropriate? a. Pain b. Impaired Skin Integrity c. Disturbed Body Image d. Disturbed Thought Processes
c. Disturbed Body Image Wounds cause emotional as well as physical stress.
A patient is admitted with a nonhealing surgical wound. Which nursing action is most effective in preventing a wound infection? a. Using sterile dressing supplies b. Suggesting dietary supplements c. Applying antibiotic ointment d. Performing careful hand hygiene
d Performing careful hand hygiene Although all of the answers may help in preventing wound infections, careful hand washing (medical asepsis) is the most important.
A nurse is developing a plan of care related to prevention of pressure ulcers for residents in a long-term care facility. Which action would be a priority in preventing a patient from developing a pressure ulcer? a. Keeping the head of the bed elevated as often as possible b. Massaging over bony prominences c. Repositioning bed-bound patients every 4 hours d. Using a mild cleansing agent when cleansing the skin
d. Using a mild cleansing agent when cleansing the skin To prevent pressure ulcers, the nurse should cleanse the skin routinely and whenever any soiling occurs by using a mild cleansing agent with minimal friction, and avoiding hot water. The nurse should minimize the effects of shearing force by limiting the amount of time the head of the bed is elevated, when possible. Bony prominences should not be massaged, and bed-bound patients should be repositioned every 2 hours.
What is a Jackson - Pratt drain?
decreases dead space by collecting drainage After breast removal, abdominal surgery
What is a hemovac drain?
decreases dead space by collecting drainage After abdominal, orthopedic surgery
What is a T-tube drain?
for bile drainage After gallbladder surgery
What is the RYB black color?
indicate the presence of eschar (necrotic tissue) which is usually black but may be brown, gray or tan. The eschar requires debridement (removal) before the wound can heal. the wound after debridement is treated as a yellow wound then a red wound.
Open wound classification
intentional or unintentional trauma Skin surface is broken = portal of entry for microorganisms Bleeding, tissue damage and increased risk for infection Delayed healing Incisions and abrasions
What is the process of edema?
interferes with the blood supply to the area (poor oxygen and nutrients to the tissue)
Eschar
is a slough or piece of dead tissue that is cast off from the surface of the skin, particularly after a burn injury, but also seen in gangrene, ulcer, fungal infections, necrotizing spider bite wounds, spotted fevers and exposure to cutaneous anthrax.
Dehiscence
is a surgical complication in which a wound ruptures along a surgical incision. Risk factors include age, collagen disorder such as Ehlers-Danlos syndrome, diabetes, obesity, poor knotting or grabbing of stitches, and trauma to the wound after surgery.
Negative-pressure wound therapy (NPWT)
is a therapeutic technique using a vacuum dressing to promote healing in acute or chronic wounds and enhance healing of second and third degree burns.
Exudate
is any fluid that filters from the circulatory system into lesions or areas of inflammation. It can be a pus-like or clear fluid. When an injury occurs, leaving skin exposed, it leaks out of the blood vessels and into nearby tissues. The fluid is composed of serum, fibrin, and white blood cells.
Granulation tissue
is new connective tissue and microscopic blood vessels that form on the surfaces of a wound during the healing process. tissue typically grows from the base of a wound and is able to fill wounds of almost any size
Ischemia
is the medical term for what happens when your heart muscle doesn't get enough oxygen. usually happens because of a shortage of blood and oxygen to the heart muscle. It is usually caused by a narrowing or blockage of one or more of the coronary arteries (which supply blood to the heart muscle).
Desiccation
is the state of extreme dryness, or the process of extreme drying. A desiccant is a hygroscopic (attracts and holds water) substance that induces or sustains such a state in its local vicinity in a moderately sealed container
What is evisceration?
wound completely separates with protrusion of viscera through the incisional area (guts are falling out)
