Athena, Thank you. I finally came up with a question about the safety of heparin vs saline flushes and received pelnty of articles. I asked for the adverse effects and received articles on HIT which was more appropriate to the question rather than just maintaining the patentcy. Next I have to identify a nursing research topic to write a journal search paper on and I am still searching. I like the idea of going to the library for suggestions. I will try that. Thanks again!
