I have been in your scenario before (just last week to be exact). We took an exam on Fluid and Electrolytes!

I bought these 2 books and they helped clarify the concepts and show the big picture:

1) Professional Guide to Pathophysiology 2nd Edition by Lippincott Williams & Wilkins

2) Pathophysiology Made Incredibly Easy

you can find them at the local book store. I bought Professional Guide to Patho that was slightly used online at amazon.com for 37 dollars.

please post any other questions!

my textbook is okay with explanation of osmolarity/osmolality,

hypotonic, isotonic, and hypertonic solutions:

Lewis, Heitkemper, and Dirksen Medical-Surgical Nursing in Canada

Fluids with the same osmolality as the cell interior as isotonic.

Solutions in which the solutes are less concentrated than the cells are

hypotonic (hypoosmolar) > H2O excess (in the cell so it'll swell and maybe burst).

Solutions in which the solutes are more concentrated than the cells are

hypertonic (hyperosmolar) > H2O deficit (in the cell so it'll shrink and maybe die)

And it includes examples of the IV solutions that are isotonic, hypotonic, or hypertonic
