IV solutions
IV solutions catergorized by osmolarity
Question | Answer |
---|---|
Isotonic | Solution has same osmolarity as the serum & other body fluids |
Hypotonic | solution has a lower osmolarity than serum & other body fluids. |
Hypertonic | Solution has a higher osmolarity than serum & other body fluids. |
2.5% dextrose in H20 | Hypotonic |
0.25% NaCl | Hypotonic |
0.33% NaCl | Hypotonic |
0.45% NaCl | Hypotonic |
5% dextrose in H20 | Isotonic |
0.9% NaCl | Isotonic |
Ringer's injection | Isotonic |
Lactated ringer's | Isotonic |
5% dextrose in 0.45% NaCl | Hypertonic |
5% dextrose in 0.9% NaCl | Hypertonic |
5% dextrose in Ringer's | Hypertonic |
10% dextrose in H20 | Hypertonic |
20% dextrose in H20 | Hypertonic |
50% dextrose in H20 | Hypertonic |
70% dextrose in H20 | Hypertonic |
3% NaCl | Hypertonic |
5% NaCl | Hypertonic |
Isotonic | NS |
Isotonic | LR |
Hypotonic | 0.45% NS |
Hypertonic | 3% Saline |
Hypotonic | Action: hydrates cells; pulls fluids from vascular space into cellular space. |
Hypotonic | Indication: tx of hypertonic dehydration |
Isotonic | Action: hydrates extracellular compartment; replaces fluid volume w/o disrupting the intracellular & interstitial volumes |
Isotonic | Indication: tx of vascular dehydration; replaces sodium chloride |
Hypertonic | Action: draws fluid out of intracellular space; leading to increased extracellular volume both in vascular & interstitial space |
Hypertonic | Indication: tx of hypotonic dehydration; tx of circulatory collapse; increase fluid shift from interstitial space to vascular space. |
