Sodium Chloride 0.45%
Hypotonic
daily maintenance of body fluid and establishment of renal function
Dextrose 2.5% in 0.45% saline

promotes renal function and urine output
Dextrose 5% in 0.2% saline
Isotonic
daily maintenance of body fluids when less Na+ and Cl- are required
Dextrose 5% in water (D5W)
Isotonic
Promotes rehydration and elimination; may cause urinary Na+ loss and good vehicle for K+
