9 Αυγ 2024 · 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.
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.
In nursing school and on the NCLEX exam, you will be required to know what type of IV fluids are considered isotonic, hypotonic, and hypertonic. In this article, I give you an easy overview of each solution and how they work on the cellular level.
2 Μαΐ 2023 · A few examples of hypotonic IV fluids include half normal saline, quarter normal saline, and 2.5% dextrose solution. These fluids are useful for rehydrating cells and treating dehydration in general. There are, however, some risks associated with these fluids.
What makes a hypotonic solution…hypotonic? Here’s a clear explanation for HOW and WHY hypertonic IV solutions work so that you can be confident in knowing which situations to use them in during nursing school.
Water freely travels outside the vasculature, so as little as 10% of isotonic fluid remains in the intravascular space. With hypotonic fluid (eg, 0.45% saline), even less remains in the vasculature, and, thus, this fluid is not used for resuscitation.
The purpose of intravenous (IV) therapy is to replace fluid and electrolytes, provide medications, and replenish blood volume. The nurse’s responsibilities in managing IV therapy include the following: assessing an IV site. priming and hanging a primary IV bag. preparing and hanging a secondary IV bag. calculating IV rates.
