What results from the use of hypertonic solutions?

Hypertonic solutions have a higher concentration of solutes compared to the fluid inside the cells. When hypertonic solutions are introduced into the body, they cause fluid to shift from the intracellular space into the vascular space to balance the osmotic pressure. This movement of fluid leads to an increase in the volume of fluid in the blood vessels, which can be beneficial in certain medical situations, such as managing severe dehydration or hypovolemia.

In this context, the correct answer emphasizes the physiological response that occurs when hypertonic solutions are administered, which is crucial for understanding fluid balance and the treatment of specific medical conditions. The ability of hypertonic solutions to draw fluid into the vascular system is significant for clinicians when addressing issues related to blood volume and circulation.
