Intravenous sugar solution, also known as dextrose solution, is a mixture of dextrose (glucose) and water. [1] It is used to treat low blood sugar or water loss without electrolyte loss. [ 2 ] Water loss without electrolyte loss may occur in fever , hyperthyroidism , high blood calcium , or diabetes insipidus . [ 2 ]
In plant cells the terms isotonic, hypotonic and hypertonic cannot strictly be used accurately because the pressure exerted by the cell wall significantly affects the osmotic equilibrium point. [5] Some organisms have evolved intricate methods of circumventing hypertonicity. For example, saltwater is hypertonic to the fish that live in
Intravenous sugar solutions, such as those containing glucose (also called dextrose), have the advantage of providing some energy, and may thereby provide the entire or part of the energy component of parenteral nutrition. Types of glucose/dextrose include: D5W (5% dextrose in water), which consists of 278 mmol/L dextrose
For example: glucose has n of 1, while NaCl has n of 2; C is the molar concentration of the solute; the index i represents the identity of a particular solute. Osmolarity can be measured using an osmometer which measures colligative properties, such as Freezing-point depression, Vapor pressure, or Boiling-point elevation.
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.

In some cases of suspensions intended for intramuscular injection, a slightly hypotonic solution is preferred in order to increase the dissolution and absorption of the drug by absorbing water from the surrounding tissues. Did the author mean to say hypertonic? Or hypotonic because the water solution absorbs into the tissue?
When a biological cell is in a hypotonic environment, the cell interior accumulates water, water flows across the cell membrane into the cell, causing it to expand. In plant cells , the cell wall restricts the expansion, resulting in pressure on the cell wall from within called turgor pressure .
