Tonicity Solutions Flashcards
What does hypotonic mean
more fluid less particles
What does hypertonic mean
more particles less fluid
Where does hypotonic solutions move the water
into interstitial spaces then cells
What are hypo solutions used to treat
people with intracellular dehydration like diabetic ketoacidosis (DKA), and hyperosmolar hyperglycemic state
What are some common hypo solutions
- 45% sodium chloride, “1/2 Normal Saline”
- 33% sodium chloride, “1/3 NS”
- 5% dextrose hypo once infused
What are hyper solutions used to treat
commonly used to treat hyponatremia
Where are hypertonic solutions going to move water
into the vascular space from the cells and interstitial fluid
What are some examples of hyper solution s
any plain glucose solution with a concentration higher than 5%. D5 0.9% NS/NaCl D5LR D10W 3-5% NS/NaCl
What are the most common examples of iso solutions
0.9% solution of NS/NaCl
Lactated Ringer’s (LR)has a little sodium, K, Ca2+
What are some more uncommon examples of iso solutions
D5 (Dextrose5) 0.225% NS/NaCl
D5W (acts as a hypotonic solution in body) because it breaks down so quickly and releases water
What are isotonic solutions used to treat
electrolyte replacement
