Population estimates indicate that the number of Minnesotans age 65 and older will rise 40 percent in the next 10 years. Students are looking beyond two-year-nursing programs to learn more about physical therapy, treatment management and psychological care while pursing a bachelor's degree. Nurse educators say two-year degree programs are not enough to keep up with the increasing demands on the profession, and more nursing students are pursuing four-year programs. Enrollment in undergraduate and graduate nursing programs increased 8.5 percent last year, from 238,799 in 2010 to 259,100 in 2011, according a recent report by the American Association of Colleges of Nursing.
