I'm a 1st yr, 1st semester NS. I've been doing ok in my classes so far as far as grades go but I think I would be better off if I could remember the signs and symptoms for many of the topics we cover. For example, tomorrow I have an exam on fluid, electrolyte, acid/base imbalance. So, hypo vs hypervolemia, hypernatrimia vs hyponatremia etc. I usually need a lot of time and repetition to memorize things but, I just get these s/s so mixed up! Anyone have any mneumonics or other techniques to remember these things? I had a lot of trouble when we covered pneumonia, COPD as well.
