Things to study up on...

Hi all,

For those of you who've already started NA school, what advice can you give me and others who will be starting this August on things to study and brush up on?

I know that each and everyone possess different levels of critical care experience (ie, some are proficient in cardiac meds/drips, some are not, some are proficient in ventilator setting manipulations and adjustments, some are not...etc, etc). But, were there any subjects in critical care nursing that you wish you might've known more about prior to the start of classes?

Please advice.

Thanks ya'll

Vinny.
