What is a key role of community health nurses?

Correct Answer: C

Rationale: The correct answer is C: Advocating for health policy changes. Community health nurses play a key role in advocating for policies that promote health and address health disparities. They work to improve population health through influencing policy decisions that impact communities. Health screenings (A) may be part of their role, but it is not a key role. Developing health policies (B) is typically done by policymakers and public health professionals, not solely by community health nurses. Providing emergency care (D) is important, but it is not a primary role of community health nurses.

Correct Answer: A

Rationale: The correct answer is A: Providing immunizations. Primary prevention aims to prevent disease occurrence before it begins. Immunizations protect individuals from infections, thereby preventing the spread of diseases within the community. Conducting health screenings (B) is more related to early detection (secondary prevention). Offering rehabilitation services (C) and providing treatment for acute illnesses (D) are considered tertiary prevention, focusing on managing and improving the outcomes of existing health conditions. Immunizations directly target disease prevention at the initial stage, making them the most effective primary prevention strategy in community health.

Correct Answer: B

Rationale: The correct answer is B: Understanding the community's needs. This is crucial as it ensures interventions are tailored to address specific issues, leading to better outcomes. By understanding the community's needs, interventions can be more targeted, relevant, and sustainable. Availability of funding (A) is important but without understanding the community's needs, resources may be misallocated. Identifying health trends (C) is valuable but does not necessarily address the root causes of community health issues. Engaging health professionals (D) is beneficial, but without a thorough understanding of the community's needs, interventions may not effectively address the overarching concerns.

Correct Answer: B

Rationale: The correct answer is B: Detecting diseases early. Secondary prevention aims to identify and treat diseases in their early stages to prevent progression and complications. Detecting diseases early allows for timely intervention and better outcomes. A: Preventing the onset of disease is primary prevention. C: Managing chronic conditions is tertiary prevention. D: Improving quality of life can be a goal of secondary prevention but is not the key goal.

Correct Answer: B

Rationale: The correct answer is B: High cost of services. This is a major barrier as it can prevent individuals from seeking necessary healthcare due to financial constraints. Lack of affordability directly impacts access to care more significantly than the other options. Cultural differences (A) can be addressed with culturally competent care. Lack of transportation (C) can be overcome with community transportation programs. Long wait times (D) can be frustrating but do not necessarily prevent access like high costs do.
