PDAs are an essential tool in health care.  Software applications like the ePocrates Rx database can reduce medical errors by giving the health care provider instant access to an up-to-date database of medications and potential interactions between drugs.  With a PDA you can download podcasts from the New England Journal of Medicine or download maps of the area where you will be traveling as a visiting nurse.  You can even store entire books on expansion cards - giving you immediate access to the 5 Minute Clinical Consult or your favorite novel.  PDAs are a powerful tool for the health care professional - personally and professionally.  The following pages will help get you started with a new pda.
