Electrolyte IV replacement fluids!?!?!

ok so we basically have to learn electrolytes, fluids and acid base balances on our own (we did 2 group activities for this topic and no lecture)

i cannot seem to grasp when you would use the following and why, for what??

1)isotonic solutions 0.9% ns ringer's lactate (?? what is this??)

2) hypotonic 0.45%ns

3) hypertonic d10w?? what is this?? 3 to 5% ns d5ns, d51/2 ns and d5rl?? huh?? can someone help me figure out an easy way to remember how and when these would be used in hyper/hypo states??

thanks!!
