The dreaded fluids & electrolytes exam


I know this has been discussed a gazillion times in the past, I have searched and searched old posts, but I was just wondering if any current students have come up with mnemonics to help with absorbing all this information on F&E's.

I have heard of ROME (respiratory opposite, metabolic equal).....anyone other suggestions?

Thanks in advance.
