Two years ago, the nurse assessed the health needs of high school students and determined that student pregnancy was a priority problem. The nurse then developed a pregnancy prevention program for the entire school district. Which finding is the best indicator of the program's effectiveness?

A. Review the previous school nurse's anecdotal documents:
While reviewing past documents may provide some context or historical insights, anecdotal evidence is subjective and may not offer a comprehensive or objective validation of current findings.

B. Obtain morbidity and mortality data for the geographic area:
Morbidity and mortality data offer objective, quantifiable information about health conditions and outcomes in the community. This data helps validate and supplement the observations from a windshield survey by providing concrete evidence on health trends, disease prevalence, and outcomes in the area.

C. Talk with teachers about their concerns for the students:
Teachers’ perspectives can provide valuable insights into student health and well-being, but this method is subjective and may not provide the objective validation needed to corroborate findings from a windshield survey.

D. Discuss with the Parent/Teacher Association (PTA) board about their perception of school events:
The PTA board’s perceptions can offer useful information about community and school events, but their feedback is subjective and may not provide the objective data needed to validate the findings of a windshield survey.

A) Provide rehabilitation services to injured farm hands:
Providing rehabilitation services is important for recovery and improving the quality of life for those who have been injured, but it addresses the consequences of injuries rather than the prevention of injuries. This action focuses on managing the outcome of injuries rather than addressing the prevention of the agent causing the injuries.

B) Work with legislators to mandate safe tractor design:
Focusing on the agent in the epidemiological triad involves addressing the factors directly responsible for causing the injury. Working with legislators to mandate safe tractor design targets the agent (the tractor and its design) to prevent injuries. By ensuring that farm machinery is designed with safety features, the risk of injury is reduced, effectively addressing the source of the problem.

C) Teach farm workers not to smoke around farm equipment:
While teaching farm workers not to smoke around farm equipment is a valuable safety measure, it addresses a risk behavior related to fire hazards rather than the machinery itself. This action focuses on modifying behaviors rather than altering the agent of injury, which is the machinery.

D) Translate written vehicle instructions into picture format:
Translating instructions into picture format can improve understanding and safety by making instructions more accessible. However, this action primarily addresses the communication of safety procedures rather than changing or improving the agent causing the injuries. Focusing on the agent involves modifying the machinery itself rather than just improving instructions.
