C10- Integumentary Flashcards
Impaired skin integrity
Break or disruption of skin or tissues
Impaired skin integrity causes: (external)
Hyperthermia
Hypothermia
Chemical
Mechanical
Humidity/moisture
Radiation
Medication
Impaired skin integrity causes: (Internal)
Altered metabolic or nutrition state
Altered circulation
Sensation
Pigmentation
Immune deficit
Altered fluid status
Factors placing a person at risk for skin alterations
Age
Changes in health status
Therapeutic measures can cause skin problems
Lifestyle variables
Wound definition
Disruption or break in normal integrity of skin
Acute wound
Heal within days to weeks
Wound edges are well approximated
Chronic wound
Do not progress through the normal sequence of repair
Wound edges often not approximated
Normal healing time is delayed
Often remain in inflammatory phase of healing
Open wound
Occur from intentional/unintentional trauma
Skin surface broken (portal of entry for microorganisms)
Bleeding
Tissue damage
Increased risk for infection
Delayed healing
Closed wound
Occurs from a blow, force, or strain
Skin surface not broken
Soft tissue damage
Internal injury and hemorrhage may occur
Intentional wound
Result of planned invasive therapy or treatment
Wound healing process:
Skin reflects condition of body
Adequate blood supply
Proper nutrition
Primary intention
Wound edges are well approximated
Secondary intention
Edges not well approximated
Take longer to heal and often develop scar tissue
Tertiary intention
Wounds left open for several days to allow edema or infection to resolve
Or fluid to drain
Then they are closed
Local factors
Factors that occur directly in the wound
Ex: pressure, maceration, trauma, edema, infection, excessive bleeding, necrosis, biofilm
Systemic factors: definition and examples
Not related to wound itself but prolong wound healing
Ex: age, circulation and oxygenation, nutritional status, medications, health status, adherence to treatment plan
What type of organ is skin?
Sensory organ
Psychological effects of wounds?
Pain
Anxiety & fear
Changes in body image
What are the 4 phases of wound healing?
Hemostasis
Inflammatory
Proliferation
Maturation/Remodeling
Blood clotting, platelet activity, brief vasoconstriction and increased capillary permeability are actions of which phase of wound healing?
Hemostasis
How fast is the inflammatory response?
Immediate
Which cells may be activated in the inflammatory phase?
Leukocytes
Macrophages
Epithelial cells
