What is a hypotonic IV solution?
IV solutions are considered hypotonic if the total electrolyte content is less than 250 mEq/L. Hypotonic IV fluids are usually used to provide free water for excretion of body wastes, treat cellular dehydration, and replace the cellular fluid.
Which IV solution to administer for fluid loss?
Which IV solution to administer is related to the reason for the fluid loss. Crystalloid solutions contain small particles that that pass easily from the bloodstream to cells and tissues. There are three types of crystalloids, given according to their tonicity, the ability to make water move into or out of a cell by osmosis.
Are the IV fluid solutions sterile?
The IV fluid solutions are considered sterile. When you open the packaging and you notice that the bag is wet or you see a leak, it must be discarded because the IV fluid solution is considered contaminated.
Are IV solutions hypertonic or hypotonic?
Colloids are IV fluids that contain solutes of high molecular weight, technically, they are hypertonic solutions, which when infused, exert an osmotic pull of fluids from interstitial and extracellular spaces. They are useful for expanding the intravascular volume and raising blood pressure.
What is an example of a hypertonic IV solution?
Examples of hypertonic solutions include D5W and 0.45% sodium chloride, D10W, and 3% sodium chloride. Hypertonic solutions may cause intravascular fluid volume overload and pulmonary edema, and they should not be used for an extended period of time.
What is a hypertonic IV solution?
Hypertonic Solutions. Hypertonic solutions have a higher concentration of dissolved particles than blood. An example of hypertonic IV solution is 3% Normal Saline (3% NaCl). When infused, hypertonic fluids cause an increased concentration of dissolved solutes in the intravascular space compared to the cells.
What type of solution is in an IV?
IV fluids are either crystalloids or colloids. A crystalloid or colloid solution can also be isotonic, hypotonic, or hypertonic, and that directly affects what that solution is used for.
Which IV fluids are hypertonic?
Types of common hypertonic fluids include:Saline Solutions: >0.9% a. 3% NaCl. b. 5% NaCl.Dextrose Solutions >=10% a. D10W. b. D20W. c. D50W.Dextrose 5% in 0.9 Normal Saline (N5NS)Dextrose 5% in 0.45% Normal Saline (D5 1/2 NS)Dextrose 5% in Lactated Ringer's (D5LR)
How do you know if a solution is hypertonic hypotonic or isotonic?
Isotonic: The solutions being compared have equal concentration of solutes. Hypertonic: The solution with the higher concentration of solutes. Hypotonic: The solution with the lower concentration of solutes.
What are isotonic and hypertonic solutions?
Isotonic solutions are most commonly used for regular maintenance of clean, healthy sinuses – a soothing wash to remove excess mucus, dust, and allergens – and for helping address such things as post-nasal drip. A hypertonic solution contains a higher concentration of salt than your body's fluids.
What type of solution is hypotonic?
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 is the example of isotonic solution?
Some examples of isotonic solutions are 0.9% normal saline and lactated ringers. When a solution has a higher solute concentration than the solution present across the semi-permeable membrane, it is known as a hypertonic solution.
What is a primary line IV?
Primary IV tubing is used to infuse continuous or intermittent fluids or medication. It consists of the following parts: Backcheck valve: Prevents fluid or medication from travelling up the IV. Access ports: Used to infuse secondary medications and give IV push medications.
When is a hypotonic IV solution used?
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.
What is a crystalloid IV solution?
Crystalloid solutions are isotonic plasma volume expanders that contain electrolytes. They can increase the circulatory volume without altering the chemical balance in the vascular spaces. This is due to their isotonic properties, meaning their components are close to those of blood circulating in the body.
What is the best solution for hypotonic IV?
Another hypotonic IV solution commonly used is 2.5% dextrose in water (D2.5W). This solution is used to treat dehydration and decreased the levels of sodium and potassium. It should not be administered with blood products as it can cause hemolysis of red blood cells.
What is IV fluid?
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.
What is sodium chloride 0.45%?
Sodium chloride 0.45% (1/2 NS), also known as half-strength normal saline, is a hypotonic IV solution used for replacing water in patients who have hypovolemia with hypernatremia. Excess use may lead to hyponatremia due to the dilution of sodium, especially in patients who are prone to water retention.
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.
What is 0.225% sodium chloride?
0.225% Sodium Chloride Solution is often used as a maintenance fluid for pediatric patients as it is the most hypotonic IV fluid available at 77 mOsm/L. Used together with dextrose.
Why is saline used in the ECF?
It is administered to correct extracellular fluid volume deficit because it remains within the ECF. Normal saline is the IV fluid used alongside the administration of blood products. It is also used to replace large sodium losses such as in burn injuries and trauma.
What are some examples of nutrient solutions?
Water is supplied for fluid requirements and carbohydrate for calories and energy. Nutrient solutions are useful in preventing dehydration and ketosis. Examples of nutrient solutions include D5W, D5NSS.
Why are colloids used in medicine?
They’re also called volume or plasma expanders, because they draw fluid from the interstitial space back into the blood vessels with oncotic pressure. Because colloids require less volume than crystalloid solutions, they are used for patients who are unable to tolerate large fluid volumes, or are malnourished.
What is the most common solution used in osmosis?
Crystalloid Solutions: Most Commonly Used. Crystalloid solutions contain small particles that that pass easily from the bloodstream to cells and tissues. There are three types of crystalloids, given according to their tonicity, the ability to make water move into or out of a cell by osmosis.
What are colloids used for?
Some of the uses for colloids are shock, external burns, pancreatitis, peritonitis, and post-op albumin loss. Common colloids are Albumin and Hespan. As a nurse, learn the types of IV solutions, and the reasons they are administered.
What is a ringer LR?
Lactated Ringers (LR, Ringers Lactate, or RL) The IV solution most similar to blood plasma concentration, it is the fluid of choice for burn and trauma patients. It used for acute blood loss; hypovolemia from third-space fluid shifts; electrolyte imbalance; and metabolic acidosis.
How does water move in cells?
Water will move from extracellular space into the cells. Hypertonic: When the extracellular fluid has more solutes (osmolarity) than within the cells, water flows out of the cells. Isotonic: Both the extracellular and intracellular fluids have the same osmolarity, so there is no movement of water between them.
What happens when fluid is lost?
Joint lubrication. When fluid is lost for any reason, electrolytes become imbalanced, body systems are stressed, and cognitive function in the brain is impaired. Blood becomes concentrated, signaling the kidneys to retain water. As a result, urine output is decreased.
What is IV therapy?
All nursing programs include fluid balance and intravenous (IV) therapy as part of the curriculum. The information about the types of IV solutions and when to use them can be confusing for a nursing student. Nurse.Plus is happy to offer this simple reference guide to the four basic types.

Isotonic, Hypotonic, & Hypertonic Fluids for Nursing Students
First, let’s get familiar with the cell and how tonicity works through osmosis.
Isotonic
The cell has the same concentration on the inside and outside which in normal conditions the cell’s intracellular and extracellular are both isotonic.
Hypotonic
The cell has a low amount of solute extracellularly and it wants to shift inside the cell to get everything back to normal via osmosis. This will cause CELL SWELLING which can cause the cell to burst or lyses.
Hypertonic
The cell has an excessive amount of solute extracellularly and osmosis is causing water to rush out of the cell intracellularly to the extracellular area which will cause the CELL TO SHRINK.
What happens when you inject hypertonic fluid?
When infused, hypertonic fluids cause an increased concentration of dissolved solutes in the intravascular space compared to the cells. This causes the osmotic movement of water out of the cells and into the intravascular space to dilute the solutes in the blood.
What is hypotonic IV solution?
Hypotonic solutions#N#have a lower concentration of dissolved solutes than blood. An example of a hypotonic IV solution is 0.45% Normal Saline (0.45% NaCl). 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. For this reason, hypotonic fluids are used to treat cellular dehydration. See Figure 15.9 [2] for an illustration of the osmotic movement of fluid into a cell when a hypotonic IV solution is administered, causing lower concentration of solutes (pink molecules) in the bloodstream compared to within the cell.
What is IV fluid?
IV fluid restores fluid to the intravascular compartment, and some IV fluids are also used to facilitate the movement of fluid between compartments due to osmosis. There are three types of IV fluids: isotonic, hypotonic, and hypertonic.
What is the definition of osmolarity?
refers to the proportion of dissolved particles in a specific weight of fluid. The terms osmolarity and osmolality are often used interchangeably in clinical practice. Intravenous fluids with a similar concentration of dissolved particles as blood plasma.
What is osmolarity in medicine?
Osmolarity. is defined as the proportion of dissolved particles in an amount of fluid and is generally the term used to describe body fluids.
What is 5% dextrose?
Hypertonic. 5% Dextrose and 0.45% Sodium Chloride (D50.45% NaCl) Used to treat severe hyponatremia and cerebral edema.
Does osmosis cause fluid movement?
Because the concentration of the IV fluid is similar to the blood, the fluid stays in the intravascular space and osmosis does not cause fluid movement between compartments. See Figure 15.8 [1] for an illustration of isotonic IV solution administration with no osmotic movement of fluid with cells.
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 is the remaining 1/3 of the body water?
2/3 of the total body water is intracellular fluid so the remaining 1/3 of the total body water is the extracellular fluid. Extracellular fluid is categorized as interstitial, intravascular, and 3rd space.
What is the process of molecules moving from a less concentrated solution to a higher concentrated solution?
Osmosis is the process of molecules moving from a less concentrated solution to a higher concentrated solution by passing through a semipermeable membrane. Water is vital for the body to function. 60% of the total body weight is the total body fluid, which can be divided into intracellular and extracellular.
Is osmolarity a hypertonic or hypotonic?
Osmolarity is equal to body fluid. Hypotonic. Osmolarity is less than body fluid. To understand hypertonic, is otonic, 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 ...
