OROMOCTO, N.B. -- From personal protective equipment, screening for symptoms, contact tracing or administering hundreds of vaccines - COVID-19 has changed the job description of many registered nurses over the last 16 months. Diane Murray knows firsthand. "The first thing I ended up going is over the Easter weekend (last year) I was screening at the emergency room in Fredericton so it was challenging to see people coming in and recognizing that, whatever their situation was, they had to be alone. It didn't matter what happened," she said. Murray has been a registered nurse for 40 years. She's nearing retirement, and sat down with CTV Atlantic to reflect on the last year of her career.
