  • Major Determinant of Plasma Osmolality?
    Sodium
  • it is determined by particle number not the nature or weight of the solute.
    osmolality
  • specimen for determination of osmolality
    urine, serum
  • principle behind the determination of osmolality
    increase in osmolality DECREASE VP and FP; INCREASE OP and BP
  • measured in ethanol poisoning

  • For every 100 mg/dL increase in glucose, serum sodium decreases by ____ mmol/L
    1.6
  • Ions are heated sufficiently, electrons are excited to a higher energy state within an atom. When they return to the ground state, they emit light energy of the same wavelength
    Flame Emission Photometry (FEP)
  • uses a semipermeable membrane to develop potential produced by having different ion concentration on either side of the membrane
