Melissa Scotting MS, RN, CNP, talked to Joe Christensen, a junior biology major Wednesday morning at Southwest Minnesota State University. Christensen and other students interested in entering the healthcare field attended Health Careers Day at SMSU. Scotting, who was a nurse for 10 years before getting her master's degree, gave a presentation earlier about what nurse practitioners do. She said nurse practitioners focus on wellness, disease prevention and treating the whole patient. They are able to take more time with patients in discussing their health.
