Fluid and Electrolytes
Fluids | a solution of solvent and solute |
Solvent | a liquid substance where particles can be dissolved |
Solute | a substance, either dissolved or suspended in a solution |
Solution | 1. homogeneous mixture of 2 or more substances of dissimilar molecular structure 2.usually applied to solids in liquids but applies equally to gasses in liquids |
Tonicity | the concentration of particles in a solution |
Isotonic | Same as plasma |
Hypotonic | have a lesser or lowers solute concentration than plasma |
Hypertonic | higher or greater concentration of solutes |
Osmole | the weight in grams of a substance producing 1.an osmotic pressure of 22.4 atm. when dissolved in 1.0litre of solution 2.(gram molecular weight) / (no. of freely moving particles per molecule) |
Osmolality | the number of osmoles of solute per kilogram of solvent |
Osmolarity | the number of osmoles of solute per litre of solution |
Isotonic solution is also called | normal saline |
