Do liquids have a fixed or variable volume?
Liquids, because they flow, can occupy whatever shape their container has, so they do not have a fixed shape. Because the particles in liquids are very close together (barely further apart than in solids) liquids do not easily compress, so their volume is fixed.
Do liquids have a fixed shape?
Because the particles cannot move around, a solid has a fixed shape. Liquids do not have a fixed shape but they do have a fixed volume. The particles are very close together. Most of the particles touch each other.
Does a liquid have a definite shape and volume?
LIQUIDS: Have a definite volume but change shape · Particles are close together, but not held as tightly as a solid.
What kind of volume does a liquid have?
Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
Has definite volume and can flow?
A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape. The change from solid to liquid usually does not significantly change the volume of a substance.
What are 5 characteristics of a liquid?
- liquid have a fixed volume but no fixed shape.
- liquids can be compressed. large pressure is required to compress them.
- liquids have lesser densities than solids.
- intermolecular forces of attraction is weaker than solids.
- they have considerable space between the particles.
What are the 4 properties of fluids?
Some of the most fundamental concepts of fluid properties are temperature, density, and composition. Mass and volume are examples of extensive properties, which are properties that depend on the amount of material. Density, temperature, and pressure are examples of intensive properties.
What are the types of fluids?
Types of Fluids
- Ideal fluid. A fluid is said to be ideal when it cannot be compressed and the viscosity doesn’t fall in the category of an ideal fluid.
- Real fluid.
- Newtonian fluid.
- Non-Newtonian fluid.
- Ideal plastic fluid.
- Incompressible fluid.
- Compressible fluid.
- Steady or Unsteady Flow.
How many types of IV fluids are there?
There are three types: isotonic, hypotonic, and hypertonic.
- Isotonic IV Fluids.
- Hypotonic IV Fluids.
- Hypertonic IV Fluids.
- Human Albumin.
- Etherified Starch.
- Plasma Protein Fraction (PPF)
What are the main types of IV fluid solution?
The most common types of solutions include normal saline (NS) and D5W. Patients may also have medications, such as potassium chloride, thiamine, and multivitamins, added to IV solutions.
How do you prevent phlebitis IV?
You can prevent many instances of phlebitis by choosing the proper insertion site, I.V. device, and securement technique. Administer irritating solutions via a central line, not a peripheral line. Check an I.V. drug book or ask the pharmacist if you’re unsure how to safely administer a medication.
Can I remove my own IV?
If they forgot to remove the IV, you can go back to the hospital to have it removed. If it’s in a vein in your arm, you are not on any blood thinners and it’s not sutured you can also pull it out yourself.
What are indications for IV therapy?
Indications for IV cannulation include the following:
- Repeated blood sampling.
- IV administration of fluid.
- IV administration of medications.
- IV administration of chemotherapeutic agents.
- IV nutritional support.
- IV administration of blood or blood products.
What is the most serious risk of intravenous therapy?
The most common include:
- Phlebitis. Inflammation of the vein.
- Extravasation. This happens when the liquid in the IV leaks to the tissue surrounding the vein.
- Air Embolism. This happens when an air bubble (or air bubbles) enters the vein.
- Hypervolaemia. This is an abnormal increase in blood volume.
What are the complications of intravenous therapy?
- Infiltration. Infiltration is the infusion of fluid and/or medication outside the intravascular space, into the surrounding soft tissue.
- Air Embolism.
- Phlebitis and Thrombophlebitis.
- Extravascular Injection.
- Intraarterial Injection.
- A Note About Oxygen.
What happens if you put an IV in an artery?
Complications of entering the artery with a large cannula intended for venous cannulation can result in complications such as temporary occlusion, pseudoaneurysm and haematoma formation.  Unrecognized arterial injection of anaesthetic drugs can cause tissue ischaemia and necrosis.
What are the types of IV infusion?
The 4 Main Types of IV Fluids
- Normal Saline. The best-known name is normal saline, sometimes called 9% normal saline, NS, or 0.9NaCL.
- Half Normal Saline. Half normal saline is also a widespread fluid.
- Lactated Ringers. Lactated Ringer’s is another highly common IV fluid used in fluid resuscitation.
What conditions require infusion therapy?
Infusion therapy is when medication or fluids are administered through a needle or catheter….It’s also used in the treatment of:
- autoimmune disorders.
- congestive heart failure.
- immune deficiencies.
- infections that are unresponsive to oral antibiotics.
What’s in a normal IV bag?
IV Fluids. IV fluids are also known as a saline solution. This sterile solution is made of sodium chloride and water. This liquid is the foundation of every IV solution, providing essential hydration, diluting medications, and facilitating the delivery of vitamins throughout the body.
