Tissue Healing and Wound Management
Show Answers:

  1. Laceration
    skin torn apart, has irregular edges
  2. Contusion
    Blow from a sharp object

    In tact skin with damage underneath
  3. Puncture
    Small wound produced by a stab with a sharp pointed object
  4. Ulcer
    A crater like wound formed from erosion of the skin/and or mucous membrane and underlying structures
  5. Incision
    Cut with a sharp object...knife, scalpel.

    Smooth edges
  6. Penetration
    Propelled object enters skin and leaves a well defined hole

  7. Necrosis
    Death of one or more cells or a portion of tissue or organ
  8. Arterial ulcer
    painful, pale, crater like lesion.

    Found on Big toe, between toes or on upper aspect of a foot.

    Is usally cold with a weak or absent pulse
  9. Venous stasis
    Necrotic, superficial, crater like lesion with minimal pain on ankles or lower legs.

    Usually caused by chronic venous congestion.

    Produces Copious Exudate
  10. Pressure Ulcer
    Any lesion caused by unrelieved pressure resulting in damage of underlying tissue.
  11. Diabetic Ulcer
    Ulcers that develope on the plantar surface of the foot, heel or anywhere pressure is exerted or an area where a person can have vascular or neurological complications from Diabetes
  12. Abrasion
    scraping or wearing away of skin
  13. What delays wound healing?
    • Advanced age
    • Malnutrition
    • Infection
    • Immunosuppression
    • Chemo
    • Decreased blood supply
  14. Ways you have decreased blood supply...
    • Ischemia
    • Venous Stasis
    • SMOKING!!!
  15. What does smoking cause?
    Nicotine causes vasoconstriction of the vessels, increasing platelet adhesiveness, RBC proliferation is reduced (diminishing oxygen transport).  Carbon monoxide diminishes oxygen transport and metabolism...less oxygen to tissues
  16. How do you assess a wound?
    • Redness (color)
    • Edema
    • Approximation
    • Drainage
    • Size
  17. How do you measure the size of a wound?
    For length and width use the face of a clock.

    • Length use 12 and 6
    • Width measure from 3 to 9...is there tunneling?

    Depth-insert a sterile cotton tipped swab in to deepest part of wound.

    Record all measurements in cm
  18. How do you describe slough of a wound?
    Tell what % of the wound  has yellow slough
  19. What does approximation mean?
    Do the edges of the wound come together?  Or is it partially separated?
  20. What is important about edema and swelling of a wound?
    Is it present in or around it?
  21. How can you tell if a wound is healing well?
    If it is black...necrotic and dead

    If it is dark pink to beefy red and moist...it is revascularized and is HEALTHY
  22. What's the significance of yellow slough in a wound?
    it is necrotic tissue which is ideal for bacterial growth.

    Purulent or green and sticky, smelly= INFECTION

    Must remove slough for wound to heel
  23. What do you do when you have red, yellow and black in your wound?
    Most severe must be removed first...

    Black, yellow...want red
  24. Primary intention and wound healing
    When the skin heals with a thin scar tissue formed at the closure site.  Wound edges approximate closely.

    Achieved by sutures or staples
  25. What happens if the doctor anticipates a large amount of drainage from a wound?
    Large amount= Jackson Pratt or Hemovac. 

    The device is kept compressed and negative pressure will withdraw fluid from the wound.
  26. Why is it important for fluid to be removed from the wound?
    To get infectious debris away from the wound
  27. Secondary intention and wound healing
    The wound is left open to heal, permitting drainage of infectious material and debris from non sterile body cavity.

    Example:  pressure ulcer, infected abscess, dehisced surgical wound

  28. How do wounds heal?
    from the edges inward and from the base upward until it is all filled in.
  29. Tiertiary Intention and wound healing
    Surgically debrided by doctor who then  leaves the wound open for 3-5 days allowing for drainage and a decreased chance of infection. 

    Wound is closed by 1st intention, leaving a smaller scar.
  30. Hydrophillic wound care product
    • Absorbent
    • Will absorb moisture and collect exudate

    Purpose is to collect newly grown tissue, absorb excessive drainage away from the wound and keep the wound free of contamination
  31. Hydrophobic wound care product
    • Non absorbent
    • Clear, transparent...acts like a second skin, but retains moisture too.

    • It is left on until they begin to leak or the protective seal is broken
    • Duoderm
  32. 3 dressings that provide moist healing....describe.
    • Hydrogels
    • Alginates
    • Foams
  33. What's used to close wound?
    Sutures, staples, steri strips and fibrin sealers
  34. Name 6 irrigating, cleansing, packing solutions
    • Normal Saline and Kara Klenz
    • Neosporin
    • Acetic Acid
    • Dakins and Betadine
  35. How often do you change dressings?
    Per physicians orders
  36. Why do we want to use a wet moist dressing?
    Allows for autolysis....mechanical debridement while allowing the bodies own natural process to debride the wound
  37. What's the cardinal rule for wounds?
    keep it moist and surrounding INTACT skin DRY
  38. Desribe nursing interventions when wound problems are identified
    • Immobilize and rest injured tissue-control bleeding
    • Protect from futher injury/infection
    • Convert to a clean wound by irrigation, packing and debridement
    • Preserve blood supply to injured tissue
    • Administer steroids with CAUTION
    • Reduce swelling by elevating injured part
    • Relieve pain
    • Monitor for infection
    • Document wound care given!!!
  39. What's autolytic debridement
    • First treatment of choice
    • Cover or pack wound with dressing to keep it moist and surrounding skin dry and in tact.
    • Allows the bodies natural defenses to clean the necrotic wound of debris.

    INFLAMMATORY process in action
  40. What's Enzymatic or chemical debridement?
    using medications or topical enzymes to break down necrotic tissue and liquefy slough
  41. What's mechanical debridement?
    Using "wet to moist" gauze allowing for moisture to help the epithelization across the wound.  Will debride necrotic tissue, but with less trauma to the wound.

    NEVER "wet to dry" any more!!  tears away newly generating tissue
  42. How do you preserve blood supply to injured tissue to promote healing?
    • CSM checks
    • Warm packs
    • Hydrotherapy/whirlpool
    • Compression dressings or wraps to promote circulation in extremeties with poor venous return
  43. What do steroids do to wound healing?
    Delays it
  44. What's the foundation of wound healing?
    Adequate NUTRITION
  45. What do you need to make sure you document with each assessment and dressing change of a wound?
  46. How do tissues repair themselves and heal?
    • Initial phase of inflammation
    • Proliferative phase of granulation
    • Remodeling phase of maturation

    POSITIVE nitrogen balance
  48. vitamins important for wound healing...
    • B-blood cell formation
    • A-epithelization & collagen synthesis

  51. Discuss nursing diagnosis related to wound care:
    • Partial thickness (dermal and epidermal damage)
    • Full thickness (tissue damage)
  52. Wound myths...
    • Dont want to leave it open...will get infected
    • Dont want to put an antacid on it, it has sugar in it and will promote bacterial growth
    • Dont put heat on it...will dry it out
    • Spend $$ on good treatments...worth it
    • Topical lotions and creams need to be administered with double gloves or you will get the affects of the ointment yourself.
  53. Describe teaching a patient how to perform self dressing change:
    • Include:
    • amount and type of dressings
    • how to obtain supplies
    • how often to change dressings

  54. Differentiate between the two types of wound separation:
    Dehiscence-partial or complete separation of upper layers of a wound

    Evisceration-total separation of layers and extrusion of internal organs or viscera thru the open wound
  55. Interventions for wound separation:
    • Dont panic
    • If dehisced-cover with non adherent dressing.
    • If eviscerated-cover wound with STERILE dressing moistened or saturated with normal saline
