Which example demonstrates a nurse using public health data collection in support of population health?

Correct Answer: C

Rationale: The correct answer is C because analyzing data from hospitals to identify the most common illnesses requiring emergency visits aligns with public health data collection for population health. This process helps in understanding health trends, prioritizing resources, and implementing targeted interventions. Surveying middle school children (A) focuses on dietary preferences, not public health data. Tracking attendance at a blood pressure clinic (B) measures service utilization, not population health trends. Interviewing a family on the emotional impact of gun violence (D) is important but does not involve public health data collection for population health.

Correct Answer: B

Rationale: The correct answer is B because promoting a weekly farmer's market for locally grown fruits and vegetables aligns with community health principles by addressing cardiovascular disease prevention through risk-factor modification at a population level. This approach promotes healthy eating habits and access to fresh produce, which can help reduce the risk factors for heart disease in the community as a whole. Choice A is incorrect as it focuses on individual counseling rather than a population-based approach. Choice C is incorrect because it pertains to managing heart disease in an individual rather than preventing it at a community level. Choice D is incorrect as it involves a specific program for community members with heart failure rather than a prevention-focused initiative for the broader population.

Correct Answer: C

Rationale: The correct answer is C because the American Nurses Association (ANA) has indeed identified nine core concepts for public health nursing. These core concepts are crucial in guiding the practice of public health nurses and ensuring high-quality care for populations. Choice A is incorrect as the scope of practice for public health nurses is different but not necessarily broader than that of a registered nurse. Choice B is incomplete and does not provide any relevant information. Choice D is incorrect as public health nurses follow standards specific to public health, not those developed for medicine. In summary, choice C is correct because it aligns with the established core concepts for public health nursing, while the other choices are either inaccurate or irrelevant.

Correct Answer: B

Rationale: The correct answer is B because managing the care of clients diagnosed with health conditions is an example of a downstream intervention. Downstream interventions focus on managing existing health issues in individuals or groups. This involves providing treatment, care, and support to those already affected by a health condition. Choices A, C, and D are not examples of downstream interventions. A focuses on prevention and promotion, C involves addressing social determinants of health at a broader level, and D targets root causes of health problems in a population, which are more upstream interventions.

Correct Answer: B

Rationale: The correct answer is B because administering pneumococcal pneumonia vaccines is a form of secondary prevention aimed at preventing complications or worsening of existing health conditions, such as pneumonia, in the senior population. This intervention directly targets a specific disease and helps reduce the likelihood of its occurrence. A, educating about signs and symptoms of influenza, is more focused on primary prevention by increasing awareness and preventing the onset of the disease. C, providing information about supportive care, is more aligned with tertiary prevention, which involves managing and reducing the impact of an already existing health problem. D, teaching how to properly wash hands, is important for infection control but falls more under primary prevention by reducing the risk of contracting infections in the first place.
