Which of the following is an example of an upstream intervention in public health?

Correct Answer: A

Rationale: The correct answer is A because advocating for policies that limit the availability of junk food in schools is an example of an upstream intervention in public health. Upstream interventions focus on preventing health issues at the population level by addressing the root causes. Limiting the availability of junk food in schools addresses the environmental factor contributing to poor dietary habits, therefore promoting healthier choices. Choices B, C, and D are not examples of upstream interventions as they focus more on individual-level interventions such as education, counseling, and access to healthy foods, rather than addressing the broader societal factors that influence health outcomes.

Correct Answer: B

Rationale: The correct answer is B because public health nursing focuses on population-level interventions through advocacy for policy changes to improve overall health outcomes. This aligns with the core principles of public health, emphasizing prevention and addressing social determinants of health. Providing direct care to individuals (A) is more aligned with clinical nursing. Focusing on the treatment of acute illnesses (C) is more of a medical approach rather than a public health approach. Conducting research to develop new medical treatments (D) is important but not the primary goal of public health nursing, which is more focused on prevention and promoting health in communities.

Correct Answer: C

Rationale: The correct answer is C: Providing rehabilitation services to individuals with chronic diseases. Tertiary prevention aims to improve the quality of life and reduce the impact of an ongoing illness or condition. Rehabilitation services help individuals manage and cope with the effects of chronic diseases, preventing further complications and promoting functional independence. A: Providing vaccines to prevent disease is an example of primary prevention, preventing the initial occurrence of a disease. B: Educating individuals about healthy lifestyles is an example of secondary prevention, aiming to detect and treat conditions early to prevent further progression. D: Screening for early signs of cancer is also an example of secondary prevention, detecting cancer at an early stage to improve outcomes.

Correct Answer: A

Rationale: The correct answer is A: Conducting a needs assessment survey. This method allows for systematic data collection from a diverse sample of community members, providing a comprehensive understanding of health needs. It ensures a holistic approach, considering various perspectives and demographics. Survey results can identify key health issues, prioritize interventions, and guide resource allocation effectively. Reviewing local health statistics (B) may not capture the nuances of community needs. Interviewing community leaders (C) may not represent the entire community. Observing behaviors (D) alone may not provide insights into underlying health issues. Conducting a needs assessment survey is the most inclusive and evidence-based method for determining community health needs.

Correct Answer: A

Rationale: The correct answer is A: Providing education on the risks of alcohol use. This intervention is most effective as it helps increase awareness and knowledge about the dangers of alcohol abuse, leading to informed decision-making. Advocating for stricter alcohol regulations (B) may help control access but may not address underlying reasons for abuse. Offering alcohol treatment services (C) is important for those already struggling, not for prevention. Providing alcohol-free events (D) is beneficial but doesn't directly address the problem of alcohol abuse.
