| hypotonic soln | hydrates cells- can decrease serum osmolality s/e-hypotension, ^ICP, anasarca .45% NaCl (half), 2.5% D5W |
| Hypertonic soln | can increase serum osmo. for pitting edema (pull out of cells), s/e-cell dehydrate, circulatory overload. 3% NaCl, D5NR, D5LR etc |
| Isotonic soln | 0.9% NaCl, LR, D5W - fill up blood space. s/e-volume overload |
| dextrose soln | start as isotonic--> hypotonic |
| D5W | used for KVO status, mixing some meds OR if hypotonic effect is desired |
| LR | don't use in alkalotic conditions |
