When a hypotonic solution is administered, it puts more water in the serum than is found inside cells. As a result, water moves into the cells, causing them to swell. ... * When hypertonic fluids are infused, water moves out of the cells in an attempt to dilute the infusate, shrinking the cells.

How do hypotonic solutions work give example?

Hypotonic Solutions

A common example of a hypotonic solution is 0.45% normal saline (half normal saline). When a patient develops diabetic ketoacidosis, the intracellular space becomes dehydrated, so the administration of a hypotonic solution helps to rehydrate the cells.

How do hypotonic IV solutions work?

Hypotonic Solutions

When hypotonic IV solutions are infused, it results in a decreased concentration of dissolved solutes in the blood as compared to the intracellular space. This imbalance causes osmotic movement of water from the intravascular compartment into the intracellular space.
