Proliferation phase of wound healing

1) Begins on third ( 3rd ) or fourth (4th) day and lasts 2-3 weeks 2) Macrophages continue to clear the wound of debris, stimulating fibroblasts, which synthesize collagen ( Main ingredient of scar tissue.) 3) New capillary networks formed to provide oxygen and nutrients to support the collagen and for further synthesis of granulation tissue. 4) Granulation tissue is deep pink a) A full thickness wound begins to close by contraction as new tissue is grown 5) Scarring influenced by degree of stress on the wound. 6) AFTER 15 -20 DAYS - The risk of wound separation or rupture decreases.

A client who had abdominal surgery 24 hours ago suddenly reports a pulling sensation and pain in his surgical incision. The nurse checks the surgical wound and finds it separated with viscera protruding. Which of the following actions should the nurse take? ( Select all that apply) ATI BOOK 1) Cover the area with saline soaked sterile dressings. 2) Apply an abdominal binder snugly around the abdomen. 3) Use sterile gauze to apply gentle pressure to the exposed tissues. 4) Position the client supine with hips and knees bent. 5) Offer the client a warm beverage , such as herbal tea.

1) Cover the area with saline soaked sterile dressings. The nurse should cover the wound with a sterile dressing soaked with sterile normal saline solution to keep the exposed organs and tissue moist until the surgeon can assess and intervene. 4) Position the client supine with hips and knees bent.

A nurse is caring for an older adult client who is at risk for developing pressure ulcers. Which of the following interventions should the nurse use to help maintain the integrity of the clients skin? ( select all that apply ) 1) keep the head of the bed elevated 30 degrees. 2) Massage the clients bony prominence frequently. 3) Apply cornstarch liberally to the skin after bathing. 4) Have the client sit on a gel cushion when in a chair. 5) Reposition the client at least every 3 hours while in bed. ATI BOOK

1) Keep the head of the bed elevated 30 degrees. The nurse should slightly elevate the client head head of bed to reduce shearing forces that could tear sensitive skin on the sacrum, buttocks, and heals. 4) Have the client sit on a gel cushion when in a chair.

Superficial wounds heal faster when kept moist.

What is the best type of wound to have?

Surgery- Clean and controlled break in the skin.

Surgi pads or abdominal pads (outside has a blue stripe)

Incision (table 38.1 pg 760)

Surgical made separation of tissues with clean , smooth edges.

What is the ONLY wound that is considered clean?

Surgical wound

Surgical wounds and open wound dressing require sterile technique.

Hematoma (table 38.1 pg 760)

Tissue injury that damages a blood vessel. Pooling of blood under the unbroken skin.

Crush ( could cause open or closed wound ) (table 38.1 pg 760)

Tissue significantly disrupted or compressed because of high level of force being applied ( e.g., person pinned against a wall by a car hitting hm at a moderate speed); May or may not be visible lacerations or maceration of tissue.

What is the best way to prevent wound infection?

To maintain strict asepsis ( the absence of bacteria, viruses, and other microorganisms) when performing wound care.

What is the worse type of wound?

Trauma - Regular or irregular and partial or full thickness.

Abrasion (table 38.1 pg 760)

Traumatic scraping away of surface layers of skin.

Does smoking delay wound healing? True or false

True

Is oxygen a good killer of bacteria? True or false

True

Excavation of the skin and or underlying tissue from injury or necrosis?

Ulceration

WBC 19000 mm , blood culturesugar positive for gram positive concise in clusters T- 101.5 , P- 124, R- 24, BP- 130/86 The reason this patient has delayed wound healing is?

Underlying infection

Autolytic debridement?

Used on small uninfected wounds ( High risk for bacteria growth)

Using cold solution lowers the wound temperature , which slows healing. ( pg 773)

What does VAC stand for?

Vacuum assisted closure This applies negative pressure to wounds and draws edges together.

Penetrating (table 38.1 pg 760)

Variable - size open wound through skin and underlying tissues made by a bullet or metal or wood fragment; May extend deeply into body. DANGEROUS , BECAUSE NO FREE FLOW OF BLOOD OUT.

Cold causes what?

Vasoconstriction

Heat causes what?

Vasodilation, which increases blood supply to the area. Heat stimulates metabolism which increases WBC and antibodies to the site. Heat may stimulate pain. Water is a good conductor of heat.

What is a good conductor of heat?

Water

Wet to dry are more rarely used as they disrupt new growth.

Mechanical debridement?

Wet to dry dressing, (nurse), ultrasound mist (painless- 2-3 times a week, or whirlpool.

Regeneration process of wound healing

When blood supply is disrupted to a tissue and cells are damaged beyond recovery, new cells , similar n structure, and function to the original cells are produced. IF the damaged tissue is a type that can regenerate: 1) Skin 2) Muscle 3) Bone liver 4) Kidney 5) Lung Unable to regenerate: 1) Heart muscle 2) Nerve cells

Induration

When skn, which s normally soft, becomes hardened.

Binders ( pg 770)

Wide elasticized fabric bands.

Immunocompromised (pg 765)

With poorly functioning immune system

Evaluation

Wound edges are well approximated

Wound infections slow the healing process

Puncture (table 38.1 pg 760)

Wound made by sharp , pointed object through skin or mucous membranes and underlying tissue. DANGEROUS , BECAUSE NO FREE FLOW OF BLOOD OUT.

What is a closed wound?

Wound without a break in the skin.

Red wounds?

Wounds that are clean and ready to heal. A protective dressing should be used

Wound vac used ?

Wounds that are difficult to heal

Sprain (table 38.1 pg 760)

Wrenching or twisting of a joint with partial rupture of its ligaments; causing swelling.
