Answers:Do you know what does isotonicity or hypertonicity and hypotonicity mean??? By the way, 0.9g% normal saline is isotonic to mammals (e.g. Locke's Solution, Tyrode's Solution, and Dale's Solution); 0.65g% normal saline is isotonic to amphibians (e.g. Ringer's Solution). Any saline preparations having salt concentration higher than the isotonic value are hypertonic and less than that are hypotonic but no trade names are available.
Answers:There are 3 or 4 IV solutions commonly used. You want to keep the solutions isotonic so that you don't rupture cells, create too much or too little urine. The isotonic IV solutions are Normal saline, used as hydration, and replacement for small amount of blood loss. You use 5% Dextrose if the person has been fasting to provide calories (unless he/she's diabetic and has high plasma glucose). There is also lactated ringer's solution used mainly perioperatively and has lactate (a glycolytic substrate) and most ions the body needs (K, Na, Cl, etc). This also used in blood replacement. Non-isotonic fluids are sometimes needed in certain circumstances. For example, if the person is hypernatremic, you might want to give him 1/2 normal saline (0.45%). Or if hyponatremic, you might want to give a more concentrated saline solution. Some drugs are incompatible with certain solutions and if you inject an incompatible drug in an IV line it will come out of solution (precipitate) clog up the line or vein - not good.
Answers:B) There will be no net movement. It will remain the same size.
Answers:When a cell and a surrounding solution are isotonic, they are at the same concentrations of electrolytes, so there will be no change in the cell. If the solution is hypertonic to the cell, then the electrolytic concentrations in the solution are greater than in the cell. The cell may allow water to diffuse outward into the solution to equalize electrolytic concentrations inside and outside the cell. If the concentration differential is too great, the cell may lose all or nearly all of its water so that it cannot sustain its own functions and may die. When a solution is hypotonic to a cell, its concentrations of electrolytes are lower than the cell's, so the cell may allow water to diffuse inward through the cell membrane in order to equalize concentrations. In cases like this, if the concentration differential is too great. the cell may allow so much water to diffuse into it that the cell membrane can rupture, destroying the cell and allowing its contents to leak out.
