Observe that fluid was "drawn" from the cell in
was reduced in size. Such an experience is
traumatic for the cell unfortunate enough to be
placed in such a situation. In relation to
intravenous fluids, a hypertonic solution would
cause cell irritation to blood cells and the cells
lining the circulatory system. The patient who is
being administered a hypertonic solution would
experience localized pain in the area of the
administration site. Examples of hypertonic
solutions are most hyperalimentation solutions and
10% dextrose solution.
A hypotonic solution is less concentrated than that
of body fluids. That is, the hypotonic solution has
less solute per volume than that of body fluid.
When placed in a hypotonic solution, a cell will
increase in size because water will enter the cell in
an attempt to equalize the concentrations of the cell
and the hypotonic solution:
As you can see, unfortunate cells exposed to
hypotonic solutions could become irritated and
damage to them could result. Examples of
hypotonic solutions are 0.45% sodium chloride
solution and sterile water for injection.
