Tonicity
the ability of a solution to cause a cell to gain or lose water
isotonic
neutral osmolarity
equal fluid in and outside of ell
hypertonic
osmolarity over 375
more fluid outside of cell than inside

water-soluble substances
diffuse rapidly
crystalloid solutions
dextrose, NS, LR, electrolytes, acid-base balance solutions
normal saline precautions
fluid overload
electrolyte imbalance

carbohydrates, provide energy
dextrose indication
mix with other IV medications, provide calories, perienteral formulas, hypoglycemia
treatment (D50)
dextrose precautions
