Answer:
Hypotonic solutions are solutions that have a low concentration of salt and can be used to replace lost fluids in patients who are dehydrated. They are often used to treat conditions such as dehydration, shock, and respiratory distress in children and in the elderly as they do have poor control of electrolytes. The Hypotonic solution that is commonly used to improve hydration is 0.45% normal saline. This has half of the solute content compared to blood composition which will create an osmotic gradient. This gradient will help to supply more water to the cells and keep cells hydrated.
Explanation:
There are three types of hydrating solutions as Isotonic, hypertonic and hypotonic. In medicine, hypotonic solutions are used to treat cellular dehydration and to assist restore blood volume. Examples of hypotonic saline are 0.45% saline or half normal saline.
While hypertonic saline is used to treat low sodium levels in the blood, it has also been shown to help lower elevated intracranial pressures. Examples of hypertonic solutions are 3% normal saline and mannitol. The isotonic solutions (0.9% normal saline, ringer’s acetate) are having a similar solute concentration to the blood which is ideal for a volume replacement without changing the solute concentration. #SPJ4
