dehydration
depletion of the bodies systemic fluid volume
overhydration
increase in the bodies systemic fluid volume
isotonic solution
a solution that has the same concentration of sodium as does the cell in this case water does not shift and no change in cell shape occurs
normal saline NS
a solution of 0.9% sodium chloride NaCl, an isotonic crystaloid
osmolarity
the ability to influence the movement of water across a semipermeable membrane
lactated ringers LR
a sterile isotonic crystaloid IV solution of specified amounts of calcuim chloride CaCL, potassium chloride KCl, sodium chloride NaCL, and sodium lactate in water
hypotonic solution
a solution that has a lower concentration of sodium than then cell, the increased osmotic pressure lets water flow into the cell causing it to swell and possibly burst
D5W
an IV solution made up of 5 % dextrose and water
alkolosis
a pathologic condition resulting from the accumulation of bases in the body, a blood pH of greater than 7.45
acidosis
a blood pH of less than 7.35, a pathologic condition resulting from the accumulation od acids in the body
ataxia
inability to coordinate the muscles properly, often used to describe a staggering gait
carpopedal spasms
contorted position of the hand in which the fingers flex in a claw like attitude and the thumb curls towards the palm
electrolytes
charged atoms or compounds that result from the loss or gain of an electron. These are ions that the body uses to preform critical metabolic functions
solute
the disolved particle contained in a solvent
solvent
the fluid that does the disolving, or the solution that contains the disolved components
solution
a liquid containing one or more chemical substances entirely disolved, usually in water
intravascular fluid
plasma, the water w/in the blood vessels which carries red blood cells, WBC and vital nutrients, normally accounts for about 4.5.% of body wieght
interstitial fluid
the water bathing the cells, accounts for about 10.5% of TBW...includes special fluid collections such as cerebrospinal fluid and intraoccular fluid
extracellular fluid ECF
the water outside the cells, accounts for 15% OF tbw and is further divided into two types of fluids... interstitial fluid, intravascular fluid
intracellular fluid
the water contained within the cells, accounts for about 45% TBW
5 types of IV solution
1. Isotonic
2. Hypertonic
3. Hypotonic
4. crystaloid
5. colloid
