Since I have not worked in an emergency room for a little over a year and a half (due to my time in Norway), I am having to re-certify on all my "special" skills. I did my basic CPR recert last week, and went today for my pediatric advanced life support (PALS). I studied over the weekend and much of last night so I could remember all the algorithms, drugs, heart rhythms, etc., and felt pretty well-prepared.
The only problem is as the class started, the instructor looks at my book and says "Oh, PALS is next week. We are doing Advanced Cardiac Life Support (ACLS) today." I was very worried then, as I had not reviewed any info for that class, but went on with it anyway (it cost $200!) In the end, I did well on all my practicals and passed the exam with a 100%!
I guess it is something that I really did learn at some point and not just remembered long enough to pass the class the first time!
