Which best describes a primary prevention strategy in community health?

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: 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.

Correct Answer: A

Rationale: The correct answer is A: Providing clean drinking water. This is an example of an environmental health intervention because it directly addresses a critical environmental factor that can impact human health. Contaminated water can lead to various health issues, so ensuring access to clean drinking water can prevent diseases and promote better health outcomes. Administering medications (B) and conducting health education sessions (C) are important health interventions but do not directly address environmental factors. Developing health policies (D) is important for promoting public health but is not a direct environmental intervention like providing clean drinking water.

Correct Answer: A

Rationale: The correct answer is A because advocating for policy changes that address social determinants of health can help address systemic inequalities and promote health equity at a population level. This approach targets the root causes of health disparities, such as poverty and discrimination. Providing direct care (choice B) may alleviate immediate health issues but does not address underlying inequities. Health education (choice C) and new health technologies (choice D) may improve individual health outcomes but do not necessarily address broader systemic issues that contribute to health inequities. Ultimately, advocating for policy changes is the most effective way to create sustainable, widespread improvements in health equity.
