  1. What percent of the normal female’s lean body weight is total body water (TBW)?
    50%
  2. What percent of the normal male’s lean body weight is total body water (TBW)?
    60%
  3. For clinical purposes in this class we can generalize that what percent of the adult LBW is TBW?
    60%
  4. The percent of TBW increases or decreases as the amount of total body water increases?
    Decreases
  5. The percent of TBW increases or decreases with age?
    Decreases
  6. What is the TBW of a newborn?
    75-85%
  7. Why is there less water in females than compared to males?
    Females have more fat
  8. Why might you need to be extremely careful about administering appropriate fluids and monitoring you newborn if it gets diarrhea?
    Because they are 75-85% of newborn’s weight is water
  9. When calculating TBW, you should use what body weight measurement?
    Hydrated/normal, unless the patient weighs more than 20% of the LBW, the use LBW
  10. What is the Devine-Devine method?
    Method used to calculate the LBW (IBW)
  11. What percent of body weight is Intracellular fluids?
    40%
  12. What percent of body weight is Intravascular fluids?
    5%
  13. What percent of body weight is Interstitial fluids?
    15%
  14. What percent of body weight is Extracellular fluids?
    20%
  15. What are the two extracellular compartments?
    Intravascular and Interstitial
  16. (True/False) ICF is poor in electrolytes like K, Mg, PO4 and proteins.
    False, ICF is rich in electrolytes
  17. What ions is the extracellular fluid rich in?
    Na, Cl and HC03
  18. What percent of total body water is Interstitial?
    25%
  19. What percent of total body water is intravascular?
    8%
  20. What fluid compartment would you expect to find Potassium and Magnesium in?
    Intracellular
  21. From what fluid compartment, ECF or ICF are blood tests taken?
    ECF
  22. What percent of total body fluids is made up of transcellular fluid?
    < 1%
  23. Where do you find Transcellular fluid?
    Peritoneal, pleural, pericardial cavities, CSF, joint fluid and GI tract
  24. What is it called to have increased transcellar fluid?
    Third spacing
  25. Other than obesity, what situation discussed in class might prompt you to use IBW instead of actual body weight?
    Person who appears dehydrated, but you do not know the non-dehydrated weight
  26. What parameter is “relative to the amount of blood the heart pumps and the extent of vasoconstriction”
    Blood Pressure
  27. By what means can you assess fluid balance?
    BP, Arterial catheter (also a BP measurement), Pulmonary artery and central venous catheters, PE, monitoring ins and outs
  28. What is the con to using catheters to monitor fluid balance?
    Invasive
  29. What is the advantage of using a central venous catheter for assessing fluid balance?
    You can concomitantly monitor RIGHT Ventricular function
  30. What is the advantage of using a pulmonary artery catheter for assessing fluid balance?
    You can concomitantly monitor LEFT Ventricular function
  31. What signs of dehydration might you look for in a PE when assessing fluid balance?
    Dry mucus membranes and breath sounds (fluid overload = wheeze/congestion)
  32. What breath sounds would indicate fluid overload?
    Wheezing or congestion
  33. About how much direct fluids should you take in per day (not in food or via metabolism)?
    1400 mL
  34. About how much fluid in food is taken in per day?
    850 mL
  35. About how much water from oxidation is created each day?
    350 mL
  36. All contributions counter, how much water is taken IN per day?
    2,600 mL
  37. How much water is lost to urine per day?
    1500 mL
  38. How much water is lost form the skin per day?
    500 mL
  39. How much water is lost through the respiratory tract per day?
    400 mL
  40. How much water is lost in the stool per day?
    200 mL
  41. What are the normal ways that you take in fluids?
    Direct fluid ingestion, food and oxidation
  42. What are the normal ways that you lose fluids?
    Urine, stool, respiration, skin
  43. What are the “sensible” water losses?
    Water loss through the stool and urine
  44. What are the “insensible” water losses?
    Water loss through respiration, skin and fever
  45. What is the major fluid composition of sensible losses?
    Water, Na and K
  46. What is the major fluid composition of INsensible losses?
    Water, with a little Na
  47. How much water is lost by sensible routes per day?
    1-1.5L
  48. How much water is lost by sensible routes per day?
    1 L
  49. What are the ways water can be lost that are not sensible or insensible?
    Nasogastic or Nasojejunal tubes, drains, fistula tracts and burns
  50. Is it easy to measure fluid loss from burns?
    No
