Courtesy of Angela Larson. After I graduated from nursing school, I practiced in critical care for 7 years as a bedside nurse. I realized during this time that I wanted more out of my practice.

That's a lesson learned from the Army's Critical Care Emergency Nurse Course being held for the first time in Madigan Healthcare System and some of Tacoma's emergency rooms.
