hi,
i also started out as a new LPN working in a fam practice office. things to study up on include: immunization schedules, coumadin therapy, injectables such as Depo shots. The physician I work with does a lot of simple proceedures such as mole removals, so I use my sterile technique quite often. You will also want to keep a current drug book handy for answering med questions from patients. There are so many things to learn and most of them are not in textbooks.

It can be a very rewarding field to work in...but be prepared for some frustrations as well. if I can answer any more questions for you, let me know.
