Fluid, electrolytes, and IV therapy Flashcards
electrolytes and fluids are important because
they are necessary for life and homeostasis (equilibrium)
a solution with an osmolality higher than that of serum
hypertonic solution
solution with an osmolality lower than that of serum
hypotonic solution
solution with same osmolality as blood
isotonic solution
osmosis is
the movement of water from an area of low solute concentration to an area of high solute concentration via a semi-permeable membrane
is the number of molecules in a liter of a solution
osmolarity
number of particles per kilogram of water
osmolality
the greater the osmolality
the greater the puling power
what percentage of the body weight is intracellular water?
40%
what percentage of the body weight is extracellular water?
20%
what are the three compartments of extracellular fluid
interstitial, intravascular (plasma), and transcellular
