Hypertonic solutions have more solutes than blood, so fluid moves out of the cells and into the intravascular space, causing cells to shrink. When To Use: These fluids are used to treat severe hyponatremia or hypoglycemia and reduce intracranial pressure.
Hypertonic solutions contain a higher concentration of solutes compared to cell contents. When administered, these solutions draw fluid out of cells through osmosis.
Isotonic, hypotonic, and hypertonic solutions are widely used in the healthcare setting and as a nurse you must know how each of the solutions work on the body and why they are given.
A hypertonic solution is a solution that has higher osmotic pressure (or has more solutes) than another solution to which it is compared. When a cell’s cytoplasm is bathed in a hypertonic solution the water will be drawn out of the cell and into the solution by osmosis.
Hypertonic refers to a solution with higher osmotic pressure than another solution. In other words, a hypertonic solution is one in which there is a greater concentration or number of solute particles outside a membrane than there are inside it.
If placed in a hypotonic solution, a red blood cell will bloat up and may explode, while in a hypertonic solution, it will shrivel—making the cytoplasm dense and its contents concentrated—and may die.
Hypotonic and Hypertonic solutions are two types of solutions based on osmolarity. A solution is comprised of two types of components: solute and solvent. A hypotonic solution has more solvent and less solute than a cell, causing water to enter the cell and leading to cell swelling.
A hypertonic solution has a higher solute concentration when you compare it to another solution or a reference point. Essentially, in a hypertonic solution, there are more solute particles and fewer water molecules.
