When would you use a hypertonic solution?
The three types of tonicity are:
- hypertonic - more solutes than water (water flows from the cell into the solution; the cell shrinks)
- hypotonic - more water than solutes (water flows into the cell from the solution; the cell swells)
- isotonic - water levels between the cell and solution are stable (no water movement)
What are the types of hypotonic solutions?
What are IV Fluids?
- To maintain or restore fluid volume
- To replace electrolytes in the intravascular compartment
- To administer medications because it is the fastest way for medicines to work.
- For parenteral nutrition for feeding replacement

When would you use a hypotonic IV solution?
Hypotonic solutions are used when the cell is dehydrated and fluids need to be put back intracellularly. This happens when patients develop diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemia.
Why would you give hypertonic IV fluids?
Clinicians use hypertonic fluids to increase intravascular fluid volume. Hypertonic saline can be utilized in the treatment of hyponatremia. Hypertonic saline and mannitol are both indicated to reduce intracranial pressure.
What is the difference between hypertonic solution and hypotonic solution?
Hypotonic has a lower concentration of fluid, sugars and salt than blood. Hypertonic has a higher concentration of fluid, sugars and salt than blood. Isotonic has similar concentration of fluid, sugars and salt to blood.
When would you use a hypertonic IV solution?
Hypertonic sodium chloride solutions are used in the acute treatment of sodium deficiency (severe hyponatremia) and should be used only in critical situations to treat hyponatremia. They need to be infused at a very low rate to avoid the risk of overload and pulmonary edema.
What IV fluid is best for dehydration?
Isotonic: This is the most common type of IV fluid. Isotonic IV fluids include normal saline, 5% dextrose solutions dissolved in water, and Lactated Ringer's solutions. These are used for dehydration caused by electrolyte imbalances as well as fluid loss from diarrhea and vomiting.
What happens if you give a hypertonic solution to a dehydrated patient?
Hypertonic Dehydration Blood osmolality is increased, causing water to shift from the intracellular to the extracellular space.
What is the difference between hypertonic saline and normal saline?
Any solution of sodium chloride (NaCl) in water with a concentration of NaCl higher than that found in physiological saline (0.9% w/v).
What is hypotonic solution used for?
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.
Does hypotonic shrink or swell?
A hypertonic solution has increased solute, and a net movement of water outside causing the cell to shrink. A hypotonic solution has decreased solute concentration, and a net movement of water inside the cell, causing swelling or breakage.
Is hypertonic low to high concentration?
A hypertonic solution is any external solution that has a high solute concentration and low water concentration compared to body fluids. In a hypertonic solution, the net movement of water will be out of the body and into the solution.
What do hypertonic solutions do?
Hypertonic solution: A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood. For example, hypertonic solutions are used for soaking wounds.
What is a hypertonic IV solution?
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.
When to use hypotonic solution?
Conversely the hypotonic solution is used when we need to put fluids into the cells for example if your patient is in Diabetic Ketoacidosis and HERE.
What happens when you have a hypertonic to hypotonic ratio?
The ratio of hypertonic to hypotonic will create a pressure and water will pull out of the tissues into the vein to attempt to create a better ratio of water and solute (notice the water followed the salt). The same is true of people who are dehydrated.
What is the specific gravity of urine for hypovolemia?
Hypovolemia with hypernatremia leaves the blood in a hypertonic state. Hypervolemia with hypernatremia leaves the blood in a mostly isotonic state. Specific Gravity of urine: 1.005-1.030. Remember “the higher the dryer” If a patients specific gravity is high, they are more dehydrated.
What is the measurement of the amount of solute mixed per volume of solvent?
Osmolality: measurement of the amount of solute mixed per volume of solvent. Tonicity: measurement of osmotic pressure between two solutions. Osmosis: the process of liquid moving across a semi-permeable membrane. Semi-permeable membrane: a membrane that allows a solvent to pass through it but not a solute.
What is hypertonic blood work?
Hypertonic (shifts fluid out of the extracellular space and into the vein, to be filtered out in the kidneys) You patient is hypotensive, dizzy, weak, and reports abdominal pain. The blood work confirms adrenal insufficiency.
Can dehydrated people use isotonic solution?
The same is true of people who are dehydrated. We give them an isotonic solution to try to expand the volume of their blood but we don’t want it to necessarily move solvent out of the vein into their tissues.
What happens when a cell is placed in a hypertonic solution?
Alternatively, if a cell is placed in a hypertonic solution, the cell will shrink due to the movement of water outside the cell through osmosis. The difference between a hypotonic solution and a hypertonic solution is tabulated below: The solution outside the cell has a higher soluble concentration than inside the cell.
What is a solution that is less than the cell sap?
A solution whose concentration is less than the cell sap or inside of a cell. A solution whose concentration is more than the cell sap or that inside a cell. A plant cell becomes turgid when putting in a hypotonic solution. A plant cell undergoes plasmolysis in a hypertonic solution.
What is the Difference Between Hypotonic and Hypertonic?
A hypotonic solution is a solution that contains low solute concentrations while a hypertonic solution is a solution that contains high solute concentrations. So, this is the key difference between hypotonic and hypertonic. Besides, a hypotonic solution has a high water potential while a hypertonic solution has a low water potential. Therefore, this is also a significant difference between hypotonic and hypertonic solutions.
What is Hypertonic?
A hypertonic solution has a high concentration of solutes than that of the inside of the cell. When a cell is immersed in a hypertonic solution, the water molecules come out from the cell to the solution. Due to the water movement from the cell to the outside, the cell becomes distorted and wrinkled. Thus, this effect is called ‘crenation’ of the cell.
What is the tonicity of a semipermeable membrane?
Tonicity is a measure of the osmotic pressure gradient and there are three states of it. These are hypertonic, isotonic and hypotonic. Among the three solutions, hypotonic solution ...
Which solution has a low solute concentration?
These are hypertonic, isotonic and hypotonic. Among the three solutions, hypotonic solution is the solution which has a low solute concentration while hypertonic solution is the solution which has a high solute concentration. The solvent concentration gradient across the two solutions is the driving force for this process.
What happens when water molecules move from the cell to the solution?
Hence, water molecules move from the cell to the solution. As a result, cells tend to shrink. Thus, this is a summary of the difference between hypotonic and hypertonic.
What are the two types of extracellular fluids that are described in terms of osmolarity?
Hypotonic and hypertonic are two types of extracellular fluids that are described in terms of osmolarity.
How to understand hypertonic, isotonic, and hypotonic?
To understand hypertonic, isotonic, and hypotonic, you must understand the process of osmosis. With osmosis, just remember LOW to HIGH. Osmosis is the process of molecules moving from a less concentrated solution to a higher concentrated solution by passing through a semipermeable membrane.
Why is isotonic solution used?
Isotonic solution is given to ensure that the cells remain in the extracellular compartment. Goal is to increase the intravascular volume. We want to treat low extracellular fluid so it makes sense that we’d use isotonic solution to keep cells in the extracellular compartment.
What size IV fluid is used for sterile?
Common IV fluid solution packagings come in different sizes, such as 50mL, 100mL, 250mL, 500mL, and 1000mL. The IV fluid solutions are considered sterile.
What are the symptoms of hypovolemia?
You should know understand and be aware of signs and symptoms of hypovolemia: Poor urine output. Poor skin turgor. Tachycardia. Hypotension. Dehydration. Fluid therapy can be lifesaving and is given when there is a loss of body water. Remember that it can cause a lot of harm when give in the wrong situation.
How to treat IV fluids as a medication?

Which solution has a higher solute concentration?
Hypertonic solutions have a higher solute concentration.
Why should hypertonic solutions not be administered peripherally?
Hypertonic solutions should not be administered peripherally because it can cause irritation and damage to the blood vessels.
What is the opposite of hypotonic?
Hypertonic Solutions. Hyper- means excess, meaning this type of solution has more solutes than fluid, which is the complete opposite of hypotonic solutions. Hypertonic solutions cause fluids to move out from inside of the cell to create homeostasis; this will cause the solutes to be normalized inside and outside the cell.
What are IV Fluids?
As a recap, intravenous fluids or solutions are fluids administered via the intravenous route, when oral administration is not recommended.
Why do solutes have the same concentration as blood plasma?
The solutes have the same concentration as the blood plasma; that’s why it expands intracellular and extracellular compartments when it’s infused. Remember the keyword “equal” when studying isotonic solutions. It has equal osmolality with the insides and outsides of the cell and has equal blood plasma concentration.
What are the signs of hypervolemia?
Observe: Hypervolemia or fluid overload signs such as (bounding pulse, high blood pressure, respiratory crackles, shortness of breath, dyspnea, edema, jugular vein distention, extra heart sounds). Prevent hypervolemia: Patients who are prescribed with isotonic solutions have hypovolemia, which may lead to hypervolemia, when not monitored properly.
What are the signs of intracranial pressure?
Monitor for signs and symptoms of fluid volume deficit such as confusion and dizziness. Also, look for signs of excessive infusion like hypotension, cellular damage, and cellular edema.
What should a nurse know about IV fluid?
During bedside care, a nurse should know why the physician prescribed a specific type of IV fluid for a certain patient . So just in case something goes wrong while the patient is on IV therapy, the nurse would be able to apply the proper interventions.
What is hypertonic sodium chloride used for?
Hypertonic sodium chloride solutions are used in the acute treatment of sodium deficiency (severe hyponatremia) and should be used only in critical situations to treat hyponatremia. They need to be infused at a very low rate to avoid the risk of overload and pulmonary edema. If administered in large quantities and rapidly, they may cause an extracellular volume excess and precipitate circulatory overload and dehydration. Therefore, they should be administered cautiously and usually only when the serum osmolality has decreased to critically low levels. Some patients may need diuretic therapy to assist in fluid excretion. It is also used in patients with cerebral edema.
Which IV solution has the same concentration of solutes as blood plasma?
Isotonic. Isotonic IV solutions that have the same concentration of solutes as blood plasma.
What are IV Fluids?
Intravenous fluids, also known as intravenous solutions, are supplemental fluids used in intravenous therapy to restore or maintain normal fluid volume and electrolyte balance when the oral route is not possible . IV fluid therapy is an efficient and effective way of supplying fluids directly into the intravascular fluid compartment, in replacing electrolyte losses, and in administering medications and blood products.
What is ringer's solution?
Lactated Ringer’s Solution (also known as Ringer’s Lactate or Hartmann solution) is a crystalloid isotonic IV fluid designed to be the near-physiological solution of balanced electrolytes. It contains 130 mEq/L of sodium, 4 mEq/L of potassium, 3 mEq/L of calcium, and 109 mEq/L of chloride.
How to tell if you have fluid overload?
