|
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 |
