ANS: B
During the twentieth century, the health and life expectancy of persons living in the United States improved dramatically. It is important for nurses to realize that of the 30 years of life expectancy gained during the century, 25 years were attributable to public health efforts. The advances in medical technology, improved physician education, and increased access to care have not had the impact on increasing life expectancy that the public health efforts have had.
