Speak to the ones that use it the most...EMT's and Paramedics!!!!! If you are fortunate enough to know some, they can really help by telling you stories or funny things they did to remember all this information! I keep my skills fresh, even though I don't do ACLS at my facility, buy hearing my husbands stories (paramedic) and him quizing me! (I keep my ACLS up because one, I love it, and two...good on the ol resume!).
Also finding out what your probelm areas are...is it all the meds? Is it the technical? Are the yes/no flowcharts a bit too much (they were for me...I had to learn it more hands on or through stories or hubbys quizes!). What sticks out as being the hardest to learn??? Then focus on your own style of learning to have it make sence (again a really good reason to have a paramedic friend handy!).
ALSO, some fire departments/paramedic stations have dumbies you can work on..some for a fee..others not. Take advantage of that if you have this resource available!
Ride alongs helped me a ton! It is one thing to read your head off..another thing to actually SEE IT in action!
Make it fun..I did and love it!!!!! (I am more paramedic at heart than nurse for sure!
