Which action is an example of primary prevention?

Correct Answer: A

Rationale: Primary prevention aims to prevent the onset of a disease or injury. Administering immunizations falls under primary prevention as it helps to protect individuals from getting the disease in the first place. Immunizations boost the body's immune system to fight off infections, reducing the likelihood of disease transmission. On the other hand, providing treatment for acute illnesses (choice B) is considered secondary prevention as it focuses on early detection and treatment to prevent the disease from progressing. Conducting health screenings (choice C) is also secondary prevention, as it involves early detection of diseases. Offering rehabilitation services (choice D) is tertiary prevention, which aims to minimize the impact of an existing disease or injury.

Correct Answer: C

Rationale: The correct answer is C because measuring changes in health outcomes provides concrete evidence of the program's impact on the community's health. This method allows for objective evaluation based on quantifiable data, showing the effectiveness of the program in improving health. Randomized controlled trials (A) may not always be feasible or ethical in community health settings. Focus groups (B) provide qualitative feedback but may not give a comprehensive view of the program's impact. Comparing costs and benefits (D) is important but does not directly reflect the program's effectiveness in improving community health.

Correct Answer: A

Rationale: The correct answer is A because social determinants, such as income, education, and social support, directly affect health behaviors and outcomes. For example, lower income levels may limit access to nutritious food or healthcare services, leading to poorer health outcomes. Choices B and C are incorrect because social determinants play a larger role than genetic predisposition and have a significant impact on overall health. Choice D is incorrect because while social determinants can influence access to health resources, their impact goes beyond just determining access.

Correct Answer: C

Rationale: The correct answer is C: Organizing community health fairs. This option engages the community directly by providing interactive health promotion activities, education, and resources. Community health fairs allow for face-to-face interactions, hands-on experiences, and networking opportunities, fostering a sense of community involvement in health promotion. Distributing health brochures (A) is passive and may not engage individuals actively. Conducting health screenings (B) is important but may not involve the broader community. Hosting educational workshops (D) is beneficial, but not as inclusive and engaging as community health fairs.

Correct Answer: D

Rationale: The correct answer is D because health informatics helps coordinate care by enabling seamless communication among healthcare providers, facilitating information sharing, and streamlining processes. This leads to improved patient outcomes and reduced duplication of services. Choice A focuses on patient safety but doesn't encompass the broader benefits of health informatics. Choice B, patient satisfaction, is important but not the primary benefit of health informatics in community health. Choice C, facilitating access to health services, is valuable but doesn't directly address care coordination, which is crucial for comprehensive and efficient healthcare delivery.
