Yes this saline is a hypertonic solution but 3% saline is also not normal. There is nothing "normal" about it. There is only one "normal saline" and that is 0.9%.
Yes. Normal saline is isotonic. Add anything to it and its omolarity increases hence normal saline with 20kcl is of a higher osmolarity than plasma hence it is hypertonic.
No, it is a hypertonic solution (if you think to a 3 g NaCl/ 100 mL solution).
0.9% saline solution is Isotonic solution
Sodium chloride 0.9 percent and normal saline are not quite the same solution. While they share the same osmolality, sodium chloride contains more salt.
I guess that depends on what you are comparing the solution to? In comparison to human blood, it is most certainly a hypertonic solution, because there is a much higher concentration of Na+ and Cl- in the solution than in the blood. An isotonic solution would only be 0.89% NaCl. See related link for more details.
0.85% nacl sol or normal saline solution is used as it is an isotonic solution which will emmulsify bacterial cells and dont cause any injury ( injury due to osmotic gradient in which cell can shrink or swell/burst ). solution upto 0.98% can be used.
A4217 sterile water saline
Anytime there is a semipermeable membrane and water with dissolved ions on both sides of the membrane you have a situation where osmosis can occur. If the solutions on each side of the membrane are equal in concentration it is said they are "isotonic" and no net movement of water will occur. If the two solutions are not equal in concentration, then one is hypertonic (more dissolved solutes) and the other is hypotonic (fewer dissolved solutes). In the case of the 10% salt solution, that is hypertonic relative to the cell. Water will move towards the hypertonic side, so water will move out of the cell and into the salt water--in other words, the cell will shrivel up (and possibly die). If instead you put the cell in distilled water, then water would rush into the cell (since it is hypertonic relative to distilled water). In that case the cell would swell up and burst. Isotonic saline solution is 0.85% or 0.9%--not quite 1% salt. They give isotonic saline intravenously when a person is dehydrated. Hope that helps. ~Kevin

Normal Saline 0.9% is called an isotonic solution. A 0.0% saline solution is called a hypotonic solution. A solution of this concentration would cause water to diffuse into the red blood cells and cause them to burst open. A 10% saline solution is called a hypertonic solution. A solution of this concentration would cause water to diffuse out of the red blood cells, making them shrivel up and shrink.
it is hypotonicQuoting from someone else's reply to this question What_is_an_example_of_a_hypotonic_solution,"0.45% NaCl (half-normal saline solution); since normal saline is 0.9% NaCl, any solution less than 9% is hypotonic".Doesn't this mean that 10% is hypertonic?
hypertonic effect
3% saline
Yes, it is considered a hypertonic solution. Normal saline that is Isotonic with body cells or in pharmaceutical preparations strength is 0.9%. Therefore, any concentration that is higher of lower is Hypertonic and hypotonic respectively.
That depends entirely on what solution it is in. Hypotonic and hypertonic are relative terms to compare to solutions usually serperated by a seme-permeable membrane.
Hypertonic dextrose solution
Because the normal saline solution is 0,9 %.
For mammals, anything greater than .9% is hypertonic.
9% NaCl is a hypertonic saline solution. Red blood cells will appear to shrink as they lose water out of the cell membrane and into the saline solution.
Normal Saline Solution in 5% Dextrose or D5NSS is a hypertonic solution. It can be used for the temporary treatment of shock if plasma expanders are not available. However, do not administer this IV for clients with cardiac or renal conditions.
