2
Q

Hypotonic Solution

A

Lower osmolality than body fluids. Administration moves water into cells from ECF by osmosis. Can cause cellular edema.

0.45% or 0.225% normal saline

3
Q

Hypertonic Solution

A

Higher osmolality than body fluids. Administration causes water to move out of cells into the ECF.
