this is not a textbook answer, but based on common sense. i want to know the name of the person taking care of me, especially if that person is looking at parts of my naked body!

isotonic solutions have the same tonicity as plasma so that when they are infused into a vein, water neither enters or leaves the cells. they have the same concentration as blood. these kinds of iv solutions are used to expand the extracellular fluid volume and do not cause any fluid to move from into or out of the blood cells. isotonic solutions have an osmolality of 240 to 340 mosm/liter.

isotonic solutions include 0.9% sodium chloride, dextrose 5% in water, dextrose 5% and 2.5% saline, dextrose 5% in water and 0.45% saline, lactated ringer's, dextrose 2.5% in 1/5 strength lactated ringers, 6% dextran and and 0.9% saline, 10% dextran and 0.9% saline and a number of formulated electrolyte solutions (i.e., normosol r, isolyte e, plasmalyte r).(
