Integumentary System

  1. Key Functions of the Integumentary System
    • Excretion of Sweat
    • Protection
    • Sensation
    • Thermoregulation
    • Vitamin D synthesis
  2. Factors Influencing Wound Healing
    • Age
    • Illness
    • Infection
    • Lifestyle
    • Medications
    • Nutrition
  3. Define Abrasion
    Wound tat occurs from the scraping w2ay of the surface layers of the skin, often as a result of trauma
  4. Contusion
    Injury where skin is not broken characterized by pain swelling and discolorations
  5. Eschar
    The necrotic and nonvialbale tissue resulting from a deep burn. This skin is hard dry and does not psosses qualities or normal skin
  6. Hematoma
    Swelling or mass or blood localized in a organ space or tissue usually cuases by a beak in a blood vessel
  7. Lacerations
    Wound or irregular tear of tissues taht is often associated with trauma
  8. Penettrating Wound
    wound taht eneter into the interior of an organ or a cavity
  9. Puncture
    Wound that is made with a sharp pointed instrument or object by penetrating through the skin inot underlying tissues
  10. Ulcer
    Lesion on the surface of the skin or the surface of a muscous membrane prduced by the sloughing of inflammatory necrotic tissue
  11. Serous Exudate
    • Clear light color with a thin waterly consistency
    • considered to be normal in a health healing wound
  12. Sanguineous Exudate
    • Red with a tan watery consistency
    • Red due to presence of bloor or may be brown is allowed to dehydrate
    • May be indeicative of new blood vessel growth or disruption of blood vessesl
  13. Serosanguineous Exudate
    • Light Red or pink color with a thin watery consistency
    • Can be normal in healthy healing wounds
  14. Seropurulent Exudate
    • Opaque yellow or tan color with a think watery consistency
    • Man be an early warning sign of infections
  15. Purulent Exudate
    • Yellow or green color with a thick viscous consistency
    • Indicative of wound infection
  16. Arterial Insufficiency Ulcers
    Occur secondary to ischemia from inadequate circulation of exygenated blood often due to complicating factors such as atherosclerosis
  17. Venous Insufficiency Ulcers
    Occur secondary to inadequate functioning of the venous system resulting in inadequate circulation and eventual tiddue damage and ulceration
  18. Characteristics of Arterial Ulcers
    • Location: Lower one third of the leg, toes,
    • Apperance: Smooth edges well defined. Lack granulation tissue, ten to be deep
    • Pain: severe
    • Pedal Pulses: diminished or absent
    • Edema: Normal
    • Skin Temp: decreased
    • Tissue Changes: Thin and shiny, hair loss, yellow nails
  19. Characteristics of Venous Ulcers
    • Location: proximal to the medial malleolus
    • Apperance: Irregular shape, Shallow
    • Pain: Mild to Mod
    • Pedal Pulses: Normal
    • Edema: Increased
    • Skin Temp: Normal
    • Tissue Changes: Flaking , dry skin, brownish discoloration
  20. Staging of Pressure Ulcers
    • Stage 1 - non blanchable erythema of intact skin
    • Stage 2 - A partial thickness skin loss that involves the epidermis and or dermis. the ulcer is superficial and presents clinically as an abrasion, a blister or a shallow crater
    • Stage 3 - A full thickness skin loss that involves damage or necrosis of subcutaneous tissue that may extend down to but not through underlying facia. The ulcer presents clinically was a deeper crater with or without undermining adjacent tissue
    • Stage 4 - A full thickness skin loss with extensive destruction tissue necrosis or damage to muscle bone or supporting structures. Undermining and sinus tracts may also be present
  21. Define Neuropathic Ulcers
    Secondary complication usually associated with a combination of ishemia and neuropathy
