The APRN is noticing a high rate of teen pregnancy and sexually transmitted diseases within the county health data. The nurse decides to survey current high school students on sexual activity and high-risk behaviors. Demographic data is gathered as a part of the research design. Twenty seven percent of high school students in this district qualify for free and reduced lunches and students who qualify for free or reduced lunches have higher rates of sexual activity than those who do not qualify for free or reduced lunches.
