Question: Why Would You Give A Patient A Hypertonic Solution?

What is an example of a isotonic solution?

Isotonic solutions contain an electrolyte balance similar to plasma in the bloodstream.

When an isotonic solution is administered, the fluid volume of the patient is increased without a fluid shift.

Common examples of isotonic solutions are 0.9% normal saline and lactated ringers..

What does hypertonic mean?

Hypertonic means that the environment outside of the cell has a higher concentration of solutes than the cell itself.

What are the 3 main types of IV fluids?

Crystalloids. Crystalloid IV solutions contain small molecules that flow easily across semipermeable membranes. They are categorized according to their relative tonicity in relation to plasma. There are three types: isotonic, hypotonic, and hypertonic.

Is salt water a hypertonic solution?

Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).

When would you use isotonic hypertonic and hypotonic solutions?

Hypertonic, Hypotonic, Isotonic IV solutions. You want to give your patients a solution that has the tonicity that is opposite their problem most of the time. For example, if your patient is dehydrated their blood is hypertonic. They will need a hypotonic solution to bring their tonicity back within normal ranges.

Why would you give a patient a hypotonic solution?

Hypotonic solution: A solution that contains fewer dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood. Hypotonic solutions are commonly used to give fluids intravenously to hospitalized patients in order to treat or avoid dehydration.

What happens when you give a hypertonic solution?

* When hypertonic fluids are infused, water moves out of the cells in an attempt to dilute the infusate, shrinking the cells. When they shrink at the I.V. … Don’t give hypertonic solutions to a patient with any condition that causes cellular dehydration, such as diabetic ketoacidosis.

Does hypertonic shrink or swell?

A hypotonic solution causes a cell to swell, whereas a hypertonic solution causes a cell to shrink.

How does isotonic solution treat dehydration?

Isotonic IV solutions restore fluid volume because they fill the tissues and maintain fluid volume more effectively than hypertonic or hypotonic solutions.

When would you give a patient a hypertonic solution?

Used to treat dehydration and decrease sodium and potassium levels. Not administered with blood as it can cause hemolysis of RBCs. Hypertonic solutions have a concentration of dissolved particles higher than plasma and an osmolality > 375 mOsm/L.

What is an example of a hypertonic solution?

Seawater has a high amount of salt particles compared to freshwater, making it a hypertonic solution. Freshwater fish can’t live in seawater because the water would rush from their cells into the surrounding saltwater.
