Study Notes

Isotonic Solutions

Isotonic solutions resemble plasma, do not shrink or swell cells, maintaining them in the vascular space.
Examples include 0.9% sodium chloride, 5% dextrose in water, and lactated Ringer's solution (LR).

Hypertonic Solutions

Hypertonic solutions have a higher concentration than isotonic solutions.
Examples include 3% sodium chloride (higher sodium concentration than 0.9% NaCl) and 10% dextrose in water.
Hypertonic solutions shrink cells, drawing fluid from the cells into the surrounding vascular and interstitial spaces. This can lead to fluid overload and pulmonary edema.

Hypotonic Solutions

Hypotonic solutions have a lower concentration than isotonic solutions.
Examples include 0.45% sodium chloride, 0.33% sodium chloride, and 10% dextrose in water and 2.5% dextrose in water.
Hypotonic solutions cause cells to swell potentially causing serious problems like cerebral edema (swelling of the brain tissue).
