Fluid and Electrolytes Flashcards
what are the most replaced electrolytes
Sodium, potassium, magnesium and calcium
water is what percent of the body
55% of body substance
can you alter the intracellular fluids
no
when we give fluid what does it go to
plasma volume
what is similar to plasma volume
cardiac output
movement of fluid through cell wall from hydrostatic pressure-
filtration
free movement of particles or solutes across a semipermeable membrane-
diffusion
when does diffusion occur
electrolyte movement
movement of water through a semipermeable membrane, the membrane must not allow particles to move
osmosis
movement of fluid through a cell or blood vessel membrane
filtration
“force”
Hydrostatic Pressure
Amount of water in a fluid is ______ related to the VISCOSITY of that fluid.
INVERSELY
what is of clinical significance for filtration
B/P
Edema
example of hydrostatic filtering forces
blood pressure
what does blood pressure do
It moves whole blood from the heart to capillaries where filtration can occur to exchange water, nutrients, and waste products between the blood and the tissues.
develops with changes in normal hydrostatic pressure differences.
edema
free movement of the solute across a permeable membrane
from higher to lower concentration
diffusion
equal exchange of particles
equilibrium
clinical significance related to diffusion
Transport of electrolytes
Glucose and insulin
Na pumps
what is important in the transport of most electrolytes and particles through cell membranes.
diffusion
movement of water (solvent) only through a selectively permeable membrane
osmosis
How well a particle type dissolves in water
solubility
Process where solutes and solution move together in response to fluid pressure to create equilibrium
osmotic pressure
filtration
isotonic soultion
same solution
300 mOsm/L
0.9% sodium chloride and lactated ringers
