Which of the following is not isotonic solution
0.5% dextrose in water
0.9% normal saline
Lactated ringer
10% dextrose in water
An isotonic solution is one that has the same osmolarity, or solute concentration, as another solution. If these two solutions are separated by a semipermeable membrane, water will flow in equal pas out of each solution and into the other. 10%dextrose in water should be administered using a central line if possible and should not be infused using the same line as blood products as it can cause RBC hemolysis.
