Several speakers addressed the school board Thursday night to express concerns about the number of nurses in county schools. While the system now employs four registered nurses to cover five schools, Coordinated School Health Coordinator Dee Anna Reynolds, along with the nurses and some parents, think the situation is an invitation to disaster. Reynolds said that the five school clinics dealt with more than 20,000 visits last year, and received 2,000 in the first month of school this year.
