  46. Review the anatomy and physiology of the skin.
    • Epidermis: composed of several layers with the stratum corneum being the outermost layer consisting of flattened, dead, keratinized cells; it protects the underlying skin and tissue from dehydrations and some chemical agents; it allows for evaporation of water and the absorption of some topical mediations. The bottom layer is the stratum basale; this layer is where cells divide, proliferate and migrate towards the surface. The epidermis is approx 1mm thick and it lacks blood supply; it functions to resurface wounds and restore the barrier against invading organisms.
    • Dermis: This is the inner layer of skin that provides strength, mechanical support and protection to underlying bone, muscle and organs. The dermis contains mostly CT, a few skin cells, collagen, blood vessels, nerves and lymph vessels. Fibroblasts are the only distinctive cell found in the dermis and its fx is to restore structural integrity and physical properties.
    • Subcutaneous: This is the third layer of skin that is composed of fat, it functions to protect the tissues and for insulation.
    • Skin Function: protection, homeostasis in water balance, temperature regulation, sensory organ and vitamin synthesis (absorption)
  47. Identify common skin, nail, hair and scalp problems and discuss appropriate nursing interventions.
    Skin: Dryness, Pruritus (itching), Sunburn, Uritcaria (hives), Primary Lesions (macules, papules, nodules, wheals, vesicles, pustules), Secondary Lesions (crusting, oozing), Bacterial Infections (folliculitis, furuncles, cellulitis), Viral Infections (herpes simplex 1 & 2, herpes zoster), Fungal Infections (tinea)Image Upload 1

  48. Differentiate bt healing by primary and secondary intention.
    • Primary Intention: When wound edges approximate, such as in the case of a surgical incision, risk of infection is low and healing occurs quickly, drainage usually stops by day 3 and the wound is usually epithelialized by day 4.
    • Secondary Intention: This type of healing involves the loss of tissue as in the case of an ulcer, burn or severe laceration. The wound edges do not approximate and it takes longer for a wound of this nature to heal, there is also a greater chance for infection
    • *The healing process is the same for all wounds, variations depend on the location and severity of the wound and the extent of the injury. Sometimes 3rd intention wound healing is used, this type of delayed wound closure is a deliberate attempt by the surgeon to allow for effective draining and cleansing of a contaminated wound. This type of wound is not closed until all evidence of edema and wound debris has been removed.
  49. Describe data to obtain when performing a wound assessment.
    • Bleeding
    • Foreign bodies/ contaminated material
    • Size
    • Progress toward healing
    • Appearance (open or closed edges, dehiscence or evisceration)

    • Serosanguineous: pale, red, watery
    • Sanguineous: bright red, active bleeding
  52. Describe the purpose and types of drains used in a surgical incision.
    • Allow drainage such as blood and exudate to drain from the wound

    • Hemovac- vacuum, empty and measure, reapply vacuum
  53. Describe the three phases of wound healing.
    • Inflammatory phase (REACTION): occurs within minutes, lasts 3-5 days
    • Proliferation phase (REGENERATION): starts on the 4th day, lasts 2-4 wks, characterized by scabbing, granulation and development of new blood vessels
    • Maturation (REMODELING): 3 wks to a year, collegen collects and scar matures
  54. Discuss the complications of wound healing.
    • Infection: bacterial, ie boil or cellulitis; viral, ie herpes; fungal, ie tinea
    • Hemorrhage: bleeding from a wound
    • Dehiscence: when the wound fails to heal properly and the skin/tissue separate; normally occurs in people who are obese, have poor nutrition or infection
    • Evisceration: protrusion of organs through a wound opening
    • Fistula: an abnormal passage between 2 organs or between an organ and the outside of the body

    • Continence/ moisture can lead to rapid skin breakdown
    • Mobility (can they change position themselves)
    • Activity ( can they ambulate)
    • Nutrition (normal wound healing requires proper nutrition)
    • Friction and shear (this will be a problem with the pt)
  57. Describe the differences bt nursing care of acute and chronic wounds.
    • Acute wounds proceed through and orderly and timely reparative process that results in sustained restoration of anatomical and functional integrity, they are usually easily cleaned and repaired and the edges are clean and intact.
    • Chronic wounds fail to proceed through an orderly and timely process to produce anatomical and functional integrity and thus heals with granulation tissue formation, can take years for large ulcers

    • Stage II: the skin is not intact, and there is partial thickness skin loss of the epidermis or dermis. the ulcer presents clinically as a superficial abrasion, blister or shallow crater
    • Stage III: Full thickness skin loss involving damage or necrosis of SQ tissue that may extend down to but not through the underlying fascia. The ulcer presents clinically as a deep crater with or without undermining of adjacent tissue
    • Stage IV: full thickness skin loss with extensive destruction; tissue necrosis; or damage to muscle, bone or supporting structures
  61. Discuss the role of nutrition in wound healing.
    • Nutrition is fundamental to normal cellular integrity and tissue repair.
    • Serum albumin should be > 3.5 mg/100ml
    • Lymphocyte count should be > 1800/mm3
    • Hgb should be at least 12g/100ml to assure there is adequate tissue oxygenation
    • Vit C promotes collagen synthesis, capillary wall integrity, fibroblast fx and immunological fx
  62. Identify nursing interventions and evaluation criteria for pt's with impaired skin and tissue integrity.
    • Prevention: do a risk assessment , reduce environmental factors (ie heat causes sweating)
    • Hygiene and Skin Care: keep skin clean and dry

  66. Describe the difference in the therapeutic effects of the application of heat and cold to an injured body part.
    • HEAT:
    • 1. 105*-110*
    • 2. Vasodialation- improves blood flow to the area, promotes nutrient delivery and waste removal
    • 3. Reduced Blood Viscosity- improves delivery of leukocytes and antibodies
    • 4. Reduced Muscle Tension- reduces pain and spasms
    • 5. Increased Capillary Permeability- promotes movement of waste products and nutrients
    • 6. Increased Tissue Metabolism- increased blood flow provides local warmth
    • *Indicated for: inflamed body parts, new surgical wounds, infected wounds, arthritis, joint disease/pain, muscle strains, LBP.

    • COLD:
    • 1. 59*
    • 2. Vasoconstriction- reduces blood flow to the affected body part, prevents swelling, reduces inflammation
    • 3. Local Anesthesia- reduces localized pain
    • 4. Reduced Cell Metabolism- reduces oxygen need of the tissue
    • 5. Increased Blood Viscosity- promotes coagulation at the injury site
    • 6. Decreased Muscle Tension- relieves pain
    • *Indicated for: direct trauma (sprains, strains, fx), superficial lacerations or puncture wounds, minor burns, arthritis, joint trauma.
  67. Identify the principles of surgical asepsis.
    • A sterile object remains sterile only when touched by another sterile object
    • Only sterile objects may be placed on a sterile field
    • A sterile object or field out of range of vision or an object held below the waist is considered contaminated
    • A sterile object becomes contaminated by prolonged exposure to air
    • When a sterile surface come in contact with a wet contaminated surface the sterile object or field becomes contaminated by capillary action
    • Fluid flows in the direction of gravity
    • The edges of a sterile field or container are considered to be contaminated
  68. Describe the indications for using sterile technique.
    • Procedures that require intentional perforation of skin

  72. Elements that are responsible for pressure ulcer development include:
    • Intensity of pressure and capillary closing pressure: pressure greater than 32mmHg
    • Duration and sustenance of pressure: time/pressure relationship
    • Tissue tolerance: skin is less sensitive than muscle
  73. Healing Process:
    is the same for all wounds, variations depend on the location and severity of the wound and the extent of the injury. Sometimes 3rd intention wound healing is used, this type of delayed wound closure is a deliberate attempt by the surgeon to allow for effective draining and cleansing of a contaminated wound. This type of wound is not closed until all evidence of edema and wound debris has been removed.
