If you fancy yourself a bit of a nurse savant, scroll through Dr. Brady Pregerson’s blog at www.erpocketbooks.com. He gives cases, charts and photos, then challenges you to determine which test, finding, cause or condition you should call. We like Brady Pregerson for a bunch of reasons…he writes really handy books for nurses and other medical personnel, he volunteered for the Peace Corps back in the day, and he writes a terrific column alongside Nurse Rebekah Child for Scrubs Magazine called “What Do Doctors Want?“
