Questions and Answers

What can lead to the impairment of an individual's ability to change positions and relieve pressure?

  • Paralysis or extreme weakness (correct)
  • Severe exercise
  • Healthy lifestyle
  • Adequate nutrition

    • Inadequate nutrition can contribute to the development of pressure injuries.

    True

    What is hypoproteinemia and how does it affect the body?

    Hypoproteinemia is an abnormally low protein content in the blood, which can lead to dependent edema and make the skin more prone to injury.

    Inadequate intake of __________ contributes to pressure injury formation.

    How does prolonged inadequate nutrition contribute to the risk of pressure injuries?

    <p>Prolonged inadequate nutrition leads to weight loss and muscle atrophy, reducing padding between the skin and bones, which increases the risk of pressure injuries.</p> Signup and view all the answers

    What role does edema play in the skin's vulnerability to injury?

    <p>Edema decreases skin elasticity and resilience, making it more prone to injury by increasing the distance between capillaries and cells, which slows oxygen diffusion.</p> Signup and view all the answers

    Explain how hypoproteinemia affects an individual's risk of developing pressure injuries.

    <p>Hypoproteinemia predisposes individuals to dependent edema, which further compromises skin integrity and increases the risk of injury.</p> Signup and view all the answers

    In what ways does immobility contribute to skin integrity issues?

    <p>Immobility limits an individual's ability to shift positions, preventing relief from pressure, which can lead to pressure injury development.</p> Signup and view all the answers

    What is the significance of skin excoriation in the context of urinary incontinence?

    <p>Skin excoriation, caused by irritants in urine, leads to loss of superficial skin layers and increases the risk of further injury.</p> Signup and view all the answers

    Study Notes

    Immobility and Pressure Injury

    • Immobility is a limitation in movement caused by conditions like paralysis, weakness, or pain.
    • Immobility prevents individuals from changing positions to relieve pressure, increasing the risk of pressure injuries.

    Inadequate Nutrition and Pressure Injuries

    • Prolonged inadequate nutrition leads to weight loss, muscle atrophy, and loss of subcutaneous tissue.
    • This reduction in padding between skin and bones increases the risk of pressure injury development.
    • Specifically, inadequate intake of protein, carbohydrates, fluids, zinc, and vitamin C contributes to pressure injuries.

    Hypoproteinemia and Edema

    • Hypoproteinemia, a low protein level in the blood, can be caused by insufficient intake or abnormal loss.
    • It predisposes individuals to dependent edema, which affects skin elasticity and resilience.
    • Edema slows oxygen diffusion to cells and metabolite removal, further increasing the risk of pressure injury.

    Immobility and Pressure Injuries

    • Immobility is a limitation in independent, purposeful movement.
    • Inability to move independently can increase pressure on the body, making it difficult to relieve discomfort.
    • Individuals with paralysis, weakness, pain, or other conditions limiting activity are at risk.

    Inadequate Nutrition and Pressure Injuries

    • Prolonged inadequate nutrition leads to weight loss, muscle atrophy, and loss of subcutaneous tissue.
    • Reduced padding between skin and bones increases the risk of pressure injuries.
    • Deficiencies in protein, carbohydrates, fluids, zinc, and vitamin C contribute to pressure injury formation.
    • Hypoproteinemia, caused by inadequate intake or abnormal loss, contributes to dependent edema.
    • Edema reduces skin elasticity and vitality, making it more prone to injury.
    • Edema slows oxygen diffusion to tissues and metabolite removal, further increasing injury risk.

    Immobility

    • Immobility involves limited and controlled independent movement.
    • Individuals normally move to alleviate discomfort from pressure.
    • Healthy individuals rarely exceed pressure tolerance.
    • Impairment like paralysis can diminish independent position changes, hindering pressure relief.

    Inadequate Nutrition

    • Prolonged inadequate nutrition leads to weight loss, muscle wasting, and subcutaneous tissue loss.
    • Reduced padding between skin and bones increases pressure injury risk.
    • Protein, carbohydrates, fluids, zinc, and vitamin C deficiencies contribute to pressure injury development.
    • Hypoproteinemia (low protein content in the blood) causes dependent edema.
    • Edema compromises skin elasticity, resilience, and vitality, increasing injury susceptibility.
    • Edema disrupts oxygen diffusion to cells and metabolite removal, hindering tissue health.

    Incontinence and Skin Breakdown

    • Moisture from incontinence softens tissues, leading to maceration and increased susceptibility to skin erosion and injury.
    • Digestive enzymes in feces, gastric tube drainage, and urea in urine contribute to skin excoriation, or loss of the superficial layers of the skin.
    • Accumulated secretions can irritate the skin, harbor microorganisms, and increase the risk of skin breakdown and infection.

    Decreased Mental Status and Pressure Injuries

    • Individuals with reduced awareness, unconsciousness, heavy sedation, or dementia are at greater risk for pressure injuries.
    • This is because they may not be able to recognize and respond to pain associated with prolonged pressure.
