As part of my job in a hospital clinic, I have to do a great deal of patient teaching-not sure if this is what you mean, though. We have to teach about age appropriate health maintainance, about the disease processes, medications/self administration of meds (such as insulin), diet, lifestyle changes and such. I also precept most of the new LPNs that are hired via agencies or regular employment. We do heath fairs in the summertime, and I teach about adult vaccines and age appropriate health screenings, such as PSA, BSE, examining testicles, cholesterol, and a host of other things.
In the past, our sister hospitals have had LPNs work as Diabetic Educators (but only RNs can be certified in Diabetic Educators). We have one that teaches how to start IV lines.
There are LPNs that teach CNAs and HHA (home heath aides) in their vocational training, medical assistants, certified CPR instructors and phlebotomy.
I LOVE teaching. I get great outcomes because I try and explain subjects as simple as possible without losing the meanings. Most come looking for me when they get a bit confused. It reinforces what I have learned and I also learn something new each time I teach because I get a chance to learn different teaching styles to reach people that don't understand, or at times, the patients come up with a phrase that is so catchy that I use it for my next session. I always take the time to obtain new information from reputable resources. The best thing you can do is take continuing education classes when you obtain your license, nursing journals and take whatever your facility offers; make friends with Nursing Staff Educators. They have loads of resources.
