The nurse recognizes that the client, based on the imbalance that is present, will require fluid re-placement with isotonic solution. One of the isotonic solutions that may be ordered by the health care provider is:

1. 0.45% saline
2. Lactated Ringer’s
3. 5% dextrose in normal saline
4. 5% dextrose in lactated Ringer’s

Lactated Ringer’s is an isotonic solution. 0.45% saline is a hypotonic solution. 5% dextrose in normal saline and 5% dextrose in lactated Ringer’s are both hypertonic solutions.
