In the early days of COVID-19, Racheal Steppe, a nurse at Baptist Medical Center South, signed up to administer coronavirus tests in downtown Jacksonville. It was a scary time, full of unknowns, and she wanted to help. She and a colleague had been talking about responding to the virus. They decided that for nurses it would be comparable to the efforts of first responders who rush to a fire or a crime scene. "This is our turn," Steppe said. "This is our time to serve." And serve she did, along with nurses across the country and world. And now it's National Nurses Week, an annual occasion to mark the work of nurses of all kinds. It began Thursday and lasts through Wednesday, the birthday of Florence Nightingale.
