  1. Four forces that control movement of water and interstitial spaces
    • Cap filtration
    • cap coloidal osmotic pressure
    • interstitial or tissue hydrostatic pressure
    • interstitial coloidal osmotic pressure
  2. who has higher body water
    • infants 70-80%
    • adults 60
    • older adults 40-50
    • men 50-60
    • women 40-
    • obesed - 30-40
  3. ADH what does it do
    is secreted by posterior pit. controls permeability of collecting tubules and ducts to water. ADH level is controlled by ECF volume and osmolality
  4. stimulation for thirst
    • increased serum osmolality, decreased blood volume
    • and angiotensin II increased if lob blood volume and pressure. .. angiotensin tesll the renal tubules to increase sodium reapsorption. and also contricts renal blood vessels to decrease glomerular filtration rate.
  5. sign and symptoms of fluid excess
    • weight gain
    • edema
    • bounding pulse
    • venous distention
    • **severe excess causes pulmonary edema shortness of breath, dyspnea cough, ascites
  6. symptoms of fluid deficit
    • increased thirst
    • increased ADH high urine specific gravity
    • decreased skin turgor
    • dry mucous membranes
    • sunken soft eyballs
    • postural hypotension
  7. factors that contribute to fluid volume excess
    • renal disease
    • heart failure
    • liver disease
    • corticosteroid excess
    • increased body sodium
    • decreased elimination of sodium
  8. what contribute to fluid deficit
    • Characterized by a decrease in ECF
    • fluid loss,
    • fistula,
    • drainage tubes
    • hemorrhage
    • severe vomitting
  9. signs and symptoms of SIADH
    • decrease urine output despite increased fluid intake, high urine osmolality, serum sodium and bun levelin decreased
    • headaches,
    • nausea
    • vomiting
    • muscle cramps
    • restlessness,
    • leth argy
    • seizures
    • coma
    • deaths
    • all those are seoncondary to hyponatremia
  10. Diabetes insipitus
    • decreased response to ADH. unable to concentrate urine.
    • excrete large volume of urine
    • excessive thirst
    • frequient urination
    • large volume dilute urine
    • nocturia
  11. K funciton
    • Maintaining ICF
    • muscle activity
    • acid base balance
    • enzyme activity
  12. ca
    • enzyme activity
    • muscles
    • sedating calming effect on nerves
    • nerve impulse transmission
    • bones/teeth
    • blood clotting
  13. Magnesium
    • nerve impulse
    • heart rhythm
    • decreases or blocks ach
    • role in converting atp to ADP
    • role in PTH and preeclampsia
    • role in secretion and action of insulin
  14. phosphorus
    • ca regulation
    • formation of teeth and bone
    • muscles
    • cell membrane
    • ATP
    • Acid base reg
    • reole in metabolism of fats and prot eins
  15. sodium
    • acid base balance
    • ner vous system
    • osmotic activity of ECF
    • movement of water
  16. factors that contribute to hyponatremia
    elderly
  17. Hypovolemic contributing factors
    • excessive sweating
    • loss of sodium from gi
  18. contributing factors to hypernatremia
    • diarrhea
    • fever
    • rapid ingestion or infusion of sodium
  19. sign and symptoms of hyponatremia
