Unit 8 Fluid Imbalance

  1. Can be caused by a loss of both water and solutes
    (electrolytes and nonelectrolytes) in ECF
    Fluid volume deficit
  2. A.K.A. Hypovolemia, dehydration, isotonic fluid loss
    Fluid volume deficit
  3. Results from loss of body fluids or decreased fluid
    intake; Most at risk: young, old, & ill
    Fluid volume deficit
  4. A.K.A “Third-spacing"
    Third Space Fluid Shift
  5. Fluid shifts of body fluids into transcellular
    compartments (not into intracellular space); example —Pleural, peritoneal, or pericardial space,
    —Joint cavities, bowel, interstitial space
    Third-Space Fluid shift
  6. Pleural
  7. Peritoneal
    around the abdomen
  8. pericardial space
    around the heart
  9. Once trapped in these spaces, the fluid does not easily move
    Third-Space Fluid shift
  10. Results in ECF volume deficit; Caused by disruption in colloid osmotic pressure, increased fluid volume, hyponatremia, severe burns, sepsis
    Third-Space Fluid shift
  11. hyponatremia
    severly low sodium
  12. shock, and increase blood pressure
  13. Decreased body weight does not occur & fluid loss
    can’t be measured, May have edema & signs of hypovolemia
    Third-Space Fluid shift
  14. ECF
    Extracellular Fluid
  15. ICF
    Intracellular Fluid
  16. Excessive retention of water and sodium in ECF
    Fluid volume excess
  17. A.K.A. hypervolemia or excess of isotonic fluids
    Fluid volume excess
  18. Causes: kidney failure, heart failure, excess IV fluid
    Fluid Volume Excess
  19. Accumulation of fluid in interstitial space= edema
    Fluid Volume Excess
  20. —Sodium, chloride, calcium, bicarbonate
    Electrolytes in ECF
  21. —Potassium, phosphorus, magnesium
    Electrolytes in ICF
  22. Measured in terms of their chemical combining power- milliequivalent (mEq)
  23. The mEq per liter for ______________ in the body vary
    within a relatively narrow range
  24. —When __________ are not in balance, the person is at risk for alterations in health
