Osmolarity of IV Solutions. Osmolarity . is the number of milliosmoles per liter of solution (mOsm/L). Normal. Osmolarity and Tonicity will control the net movement of water and electrolytes throughout the body. IV solutions are classified according to their osmolarity (isotonic, hypotonic, or hypertonic) Isotonic. Isotonic solutions

The emergency room health care team disagrees about which IV solution to give the firefighter. Her osmolarity is low, and her body weight and blood pressure indicates that she is a little dehydrated (needs some fluid in cells). Refer to the list of IV solutions on page 156, Table 5-9.

The normal tonicity of body fluids is 275-295 mOsm/Kg. In isotonic dehydration, the serum sodium concentration is between 130 and 150 mEq/L. This is the most common type of dehydration and the type with the best prognosis. ... IV solutions with hypertonic dextrose (D10 or greater) can produce hypokalemia (and hypophosphatemia). Insulin in IV ...

A peripheral IV that’s been capped and flushed with saline is still called a “hep-lock” nowadays, but we flush very few lines with heparin any more – dialysis catheters come to mind, and even they get flushed with ACD these days. ... but one thing to understand is the idea of tonicity – some fluids are equal to blood in concentration ...

12. You decide to buy a new fish for your freshwater aquarium. When you introduce the fish into its new tank, the fish swells up and dies. You later learn that it was a fish from the ocean. Based on what you know of tonicity, the most likely explanation is that unfortunate fish went from a(n) _____ solution into a(n) _____ solution.

See the question about the 5%/0.9% NaCl IV. It combines our discussion of facilitated diffusion and osmoloarity/tonicity. Here is the question: a solution of 5% dextrose + 0.9% NaCl is initially hyperosmotic to blood. However, when you inject it via an IV, the solution becomes isotonic! How can this be the case? (Note: dextrose = glucose.

IV solutions are categorized by dissolved components (crystalloid and colloid) and by tonicity (isotonic, hypotonic, hypertonic). Crystalloid solutions are dissolved crystals in water, and contain compounds that quickly disassociate in solution. These solutions are the best choice for the patients who need fluid replacement.

Normal osmolarity of blood/serum is about 300-310 mOsm/L. The tonicity of an IV fluid dictates whether the solution should be delivered via the peripheral or central venous route. Hypotonic and hypertonic solutions may be infused in small volumes and into large vessels, where dilution and distribution are rapid.

• The cell will expand. If too much water enters the cell eventually it could undergo hemolysis or break open. This is why hypotonic IV solutions are only used in specific clinical situations. Page 23. Summary • Fluids are composed of water and all the substances (solutes) dissolved in the water in the body.

1. Since the tonicity is low, avoid using in head injury patients. 2. Use sterile technique in venipuncture and equipment assembly, with all venipunctures 3. Do not administer quantity in excess of that required to keep vein open or administer appropriate dose of medication. 4.
