Your patient has had abdominal surgery for a ruptured appendix and requires postoperative care and dressing changes. The wound has been left open, and irrigation's are ordered. When irrigating a wound, it is most important to:
irrigate slowly to prevent discomfort
ensure the solution reaches the depths of the wound
prevent wetting of the bed and covers
use vigorous irrigation flow from the syringe
If a wound appears infected, you should:
cleanse it with an antiseptic solution
obtain an order for culture to be performed
apply an antibiotic ointment
change the dressing every 2 hours
The assessment of the wound indicates healing is occurring when:
the center tissue is white
bleeding has stopped
there is no further drainage from the wound
pink granulation tissue is visible
When assessing for wound infection, you know that signs of wound infection may be:
a rise in temperature
increasingly rapid respirations
a WBC above 10,000/dl
restlessness and discomfort
purulent drainage
tenderness around the wound
When caring for a pressure ulcer, you know that:
eschar must usually be removed before the wound will heal
pink granulation tissue should be cleansed with antiseptic solution
keeping the wound dry and covered will aid healing
heat treatments hurt new tissue and slow healing
Hydrocolloid dressing are useful for open wound dressings because they:
keep the wound moist while blocking entry of microorganisms
debride the wound and soften eschar
supply bacteriostatic action to clean the wound
contain an antiseptic, allow moisture to evaporate, and protect the wound.
If you are assisting a surgical patient to the bathroom and he suddenly says, "It feels like something has given way," you would suspect that has occurred.
Proper technique for removal of sutures is to:
clip the suture below the knot
assure the patient that suture removal does not hurt
refrain from pulling an exposed suture through the wound
apply a Steri-strip before removing the suture
Heat is helpful in healing a wound because it:
causes constriction of blood vessels and reduces edema
soothes nerve endings, lessening pain
causes vasodilation, bringing oxygen and nutrients to the injury
causes vasodilation, which moves blood out of the area
The ulcer appears as a defined area of persistent redness in lightly pigment skin, whereas in darker skin tones, the ulcer may appear with persistent red, blue, or purple hues.
Stage 1
Stage 2
Stage 3
Stage 4
Eschar
Partial thickness skin loss involving epidermis, dermis, or both. The ulcer is superficial and presents clinically as an abrasion, blister or shallow crater.
Full thickness skin loss involving damage to, 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.
Full thickness skin loss with extensive destruction, tissue necrosis, or damage to muscle, bone, or supporting structures. Undermining and sinus tracts also may be present.
An unstageable wound, that is thick dry black necrotic tissue.
These wounds heal more quickly, as new skin cells are produced by the epithelial cells remaining in the dermal layer of the skin. Ex: 1st or 2nd degree burns
Partial-thickness
Full-thickness
Contusion
Hematoma
These wounds occur when the dermal layer is no longer present except at the wound margins all the way to tendons or bones.
A closed wound that tissue injury without breaking of skin.
Contusion (bruise)
Sprain
Incision
A closed wound that tissue injury that damages a blood vessel; pooling of blood under the unbroken skin.
A closed wound that wrenching or twisting of a joint with partial rupture of its ligaments; causes swelling
Contusion (bruises)
An open wound that is a surgically made separation of tissues with clean, smooth edges.
Laceration
Puncture
Abrasion
an open wound that is from traumatic separation of tissues with irregular, torn edges.
An open wound that is from a traumatic scraping away of surface layers of skin.
Penetrating
An open wound that is a variable size through the skin and underlying tissues made by a bullet or metal or wood fragment; may extend deeply into the body.
An open wound made by a sharp, pointed object through the skin or mucous membranes and underlying tissue.
An open wound that is tearing away of a structure or a part, such as a fingertip, accidentally or surgically.
Avulsion
Ulceration
Perforation
An open wound that is an excavation of skin and underlying tissue injury or necrosis.
Crush
An open wound is an internal organ or body cavity tissue opened, usually because of infection or a penetrating wound.
An open wound that is a tissue significantly disrupted or compressed because of high level of force being applied.
This occurs in the form of fibrous connective tissue that does not have the same functional characteristics as the tissue lost when the wound occurred.
Replacement
Regeneration
Inflammation
Necrosis
If the blood supply has been disrupted to the new wound bed and necrosis has occurred, the affected tissue must heal by regeneration replacement inflammation debridement( regeneration, replacement, inflammation, debridement ).
Which of these affected tissues will regenerate if lost.

No matter what cause of the wound, healing occurs in 3 2 4 5( 3, 2, 4, 5 ) distinct phases.
A phase of the wound healing process begins immediately after injury and lasts about 3 or 4 days. It includes constriction of blood vessels, platelet aggregation, and the formation of fibrin.
Inflammatory phase
Proliferation or reconstruction phase
Maturation or remodeling phase
The inflammatory phase is the process of
hemostasis
homeostasis
hemorrhage
Full thickness wounds heal how
from bottom-up
from top to bottom
over 24 hours
by drying out the bed
The collection of plasma and electrolytes leaking into the interstitial spaces causes edema collagen necrosis inflammation( edema, collagen, necrosis, inflammation ).
The phagocytic cells remove debris and protect against bacterial invasion by engulfing of microorganisms or foreign particles called .
The clinical signs of inflammatory process are as follows:
Swelling or edema
Erythema
Cyanosis
increased temperature
pain steming from pressure
numbness
loss of function
This phase of wound healing begins on the third or fourth day after injury and lasts 2 to 3 weeks while macrophages continue to clear the wound of debris, stimulating fibroblasts, which synthesize collagen.
This phase of wound healing begins about 3 weeks after injury, scar formation, is the process of collagen lysis and collagen synthesis by the macrophages to produce the strongest scar tissue possible.
If collagen overgrowth occurs, which is frequent in dark-pigmented skin, a permanent raised, enlarged scar called this occurs

A localized infection called an abscess hematoma cellulitis fistula( abscess, hematoma, cellulitis, fistula ) is an accumulation of pus made up of debris from phagocytosis when microorganisms have been present.
This is an inflammation of the tissue surrounding the initial wound, with redness and induration.
Cellulitis
Fistula
Exudate
Abscess
This is a abnormal passage or communication usually formed between two internal organs or leading from an internal organ to the surface of the body.
The best way to prevent wound infection is to maintain strict asepsis when performing wound care.
Dehiscense Evisceration Sinus Laceration( Dehiscense, Evisceration, Sinus, Laceration ) is the spontaneous opening of an incision, an abdominal wound often involves separation of the layers beneath the skin as well.
This is the protrusion of an internal organ through the incision.

If dehiscence occurs which steps should be taken
lay the patient in supine
lay the patient in semi-fowlers
place a large sterile dressing
push the contents back in
towels soaked in normal saline
make patients NPO immediately
There are three basic wound types: red, yellow and black. the type of wound indicates the type of dressing needed. This wound is clean and ready to heal.
Red wound
Yellow wound
Black wound
There are three basic wound types: red, yellow and black. the type of wound indicates the type of dressing needed. This wound has a layer of fibrous debris or exudate. Sloughing may cause drainage and needs to be frequently cleansed and should have a dressing that will absorb the drainage and debride the surface mechanically. These wounds often become infected.
Red wounds
Yellow wounds
Black wounds
There are three basic wound types: red, yellow and black. the type of wound indicates the type of dressing needed. These wounds need debridement of the eschar to heal.
This type of drain is a flat rubber tube, often a safety pin is placed external end of the drain to prevent it from slipping into the wound.

A plastic drainage tubes can be connected to a drainage system that is compressed and closed to create suction, this device contains springs and can hold up to 500 mL of drainage.
Jackson Pratt or JP
A plastic drainage tube can be connected to a drainage system that is compressed and closed, applying slight suction to the drainage tube to help evacuate wound fluids. You must compress the bulb of this device and it holds about 100 mL of drainage.
A transparent film dressing, such as , allows you assess the wound without removing the dressing, these are often used to cover intravenous catheter sites.
When taping a dressing to your patient you should tape the dressing across the joint or crease up and down along the edges of bandage( across the joint or crease, up and down along the edges of bandage ) to get correct a adhesion.
Wound cleansing should be performed by warm cool( warm, cool ) isotonic saline.
Surgical wounds and open wounds dressing require sterile nonsterile( sterile, nonsterile ) technique.
If the wound is infected, the dressing may be changed how often?
12-24 hours
8-12 hours
48-72 hours
3 times a week
Sometimes a wet to dry dressing may also be applied to help he sloughing of necrotic tissue by what
