NSG 231 Exam #1 IV therapy-Questions with Correct
Answers/ Verified/ Latest Update
What is an Isotonic solution? - ✔✔A solution in the IV that is equal to the concentration in
the body - no net movement of sodium
Reasons to give Isotonic solution - ✔✔To maintain or slowly raise blood pressure
Types of Isotonic Solution - ✔✔Normal Saline: 0.9%
D5W *** works as hypotonic solution
Tx of metabolic alkalosis
D5W - ✔✔Classified as an Isotonic solution, but works as a hypotonic solution - The glucose
is immediately used up by the cells and all that is left is extra water - thus water will move
into the cells causing edema (if too much)
tx of dehydration, hypernatremia,
Hydrostatic Pressure - ✔✔pressure that a fluid exerts on a container - wants to escape the
vascular space
Oncotic Pressure - ✔✔proteins attract water and sodium - so they want to stay in the
vascular space; Greater concentration of proteins = greater OP
Types of Hypotonic Solutions - ✔✔0.45% NaCl (Saline Solution)
**D5W - works as Hypo but, classified as Isotonic
What is a hypotonic solution? - ✔✔A solution that has a smaller concentration of NaCl than
of the body
Reasons to give hypotonic solution - ✔✔patient is dehydrated - gives cells more water
