LEC 2: Definitions Flashcards
Hemorrhave
Blood loss
Hypovolemia
Low blood volume
Hypovolemic Shock
Inadequate perfusion of tissue
Thrombus
Blood clot
Embolus
Dislodged blood clot
Atelectasis
Collapsed alveoli
Pneumonia
Lung infection
Hypoxemia
Low oxygen in blood
Pulmonary Embolism
Clot in the lungs
Paralytic Ileus
Diminished or absent peristalsis
- Not moving; stomach gets bigger
Wound Dehiscence
Separation wound edges at incision line
Wound Evisceration
Protrusion of internal organs at suture line
Skin Breakdown
Pressure injury
Dermatomes
Area on the skin that is supplied by spinal nerve
Pressure Ulcers
Localized injury to skin and underlying tissue, usually over a bony prominence, as a result of pressure, or in combination with shear and/or friction
Shear
The force exerted parallel to the skin and results from both gravity pushing down on the body and resistance (friction) between the patient and a surface
Undermining
Tissue destruction extending under intact skin along the wound margin
Tunneling
(Sinus tract) course of path of tissue destruction occurring in any direction from the wound bed
Montgomery Ties
Adhesive ties (tape) affixed to the skin so as to provide a method of securing a bandage and subsequently changing it without having to replace the tape each time. Most often used for abdominal incisions but still requiring frequent dressing changes.
Fracture
A break in continuity of the bone; can be complete or incomplete
Pathological Fracture
May occur during normal activity or following minimal injury when a bone is weakened by a disease process
Fatigue or Stress Fracture
Normal bone subjected to repeated stress without bone and muscle recovery
Osteoarthritis
Degenerative joint disease
