Final answer:
Health indicators a public health nurse may use for a program based on Healthy People 2020 include tobacco usage, substance abuse, exercise frequency, and environmental quality. These indicators are integral to tracking and improving public health under the initiative's goals.
Step-by-step explanation:
A public health nurse developing a program based on the government initiative Healthy People 2020 may use a variety of health indicators to shape the program. These indicators are reflective of broader public health goals that aim to track and improve population health. Among the options listed, the nurse may consider:
Tobacco usage, as it is a leading cause of preventable disease and death.
Substance abuse, since it has far-reaching impacts on both individual health and societal welfare.
Exercise frequency, which is a critical component of preventing chronic diseases and promoting wellness.
Environmental quality, because it plays a fundamental role in health and is an essential part of the initiative to prevent disease through environmental health measures.
While technology usage can have an implication on health, it is not specifically a focus of the Healthy People 2020 initiative health indicators. Indicators like tobacco usage, substance abuse, exercise frequency, and environmental quality have been recognized as critical factors affecting public health and are therefore closely monitored and targeted for improvement.
