Skills Test 3 Flashcards
Sanguineous
Large amounts of red blood cells
Full thickness skin loss involving damage or necrosis of subcutaneous tissue that may extend down to but not through underlying fascia
Stage III
Renewal of tissues
Regeneration
Risk factors for pressure ulcers
Friction and sheering Immobility Inadequate nutrition Incontinence Decreased mental status Diminished sensation Excessive body heat Advanced age Chronic medical conditions
Full thickness skin or tissue loss depth unknown
Unstageable
Tissue surfaces have been approximated (closed) and there is minimal or no tissue loss
Primary intention healing
Non blanch able erythema signaling potential ulceration
Stage I
Secondary intention healing
Pressure ulcer
Repair time is longer
Scarring is greater
Susceptibility to infection is greater
Wound left open 3-5 days to allow edema or infection to resolve then closed with sutures or staples
Tertiary intention
Most commonly used dressing on a wound. Permits air to circulate
Gauze
Begins immediately after injury and lasts 3-6 days
Inflammatory phase
Results from vasoconstriction of the larger blood vessels in the affected area
Hemostasis
Cell migration
Leukocytes ( specifically neutrophils) move into the interstitial space
Phagocytosis
Macrophages engulf microorganisms and cellular debris
Serous fluid
Serum
Ex- closed surgical incision or liquid glue on a laceration
Primary intention healing
Pressure ulcers are due to what
Localized ischemia
Complications of wound healing
Hemorrhage
Infection
Dehiscence
Evisceration
Factors affecting wound healing
Developmental consideration
Nutrition
Lifestyle
Medications
Preventing pressure ulcers
Provide nutrition
Maintain skin hygiene
Avoid skin trauma
Provide supporting devices
Strip of cloth used to wrap some part of the body
Bandage
Elasticized bandages
Provide pressure to the area
Binders
Type of bandage designed for a specific body part
Purulent
Pus
Partial thickness skin loss involving epidermis and possibly the dermis
Stage II
Full thickness skin loss with tissue necrosis or damage to muscle,bone or supporting structures.
Stage IV
Maturation phase
About day 21 and can extend 1-2 years
Wound is remodeled and contracted
Scar becomes stronger but the repaired area is never as strong as the original tissue
Sitz bath
Used to soak a patients perineal or rectal area
Teds
Used to facilitate venous return from the lower extremities
Prevent venous stasis and DVT
Reduce peripheral edema
Sutures
Thread used to see body tissues together
Pulmonary embolism
Clot formed elsewhere that travelled to the lung
Control severe bleeding by
Applying direct pressure over the wound
Elevating the involved extremity
Prevent infection in a wound by
Cleaning or flushing abrasions or lacerations with normal saline
Cover the wound with a clean dressing
Control swelling of a wound by
Applying ice over the wound and surrounding tissues
Signs of shock In a patient
Rapid thready pulse
Cold clammy skin
Pallor
Lowered blood pressure
Size of needle and syringe needed to irrigate a wound
18-19 gauge
30-60mL
Heat
Vasodilation Increases capillary permeability Increase cellular metabolism Increases inflammation Sedative effect
Most common type of contaminant of blood cultures
Epidermis
Specimen should never be refrigerated
Blood culture
Serious disease characterized by chills, fever, prostration, and the presence of bacteria or their toxins in the bloodstream
Septicemia
