What is the primary purpose of conducting a health survey in a community?
Correct Answer: B
Rationale: The correct answer is B: To gather data on health status and needs. The primary purpose of conducting a health survey in a community is to systematically collect information on the health of the population, identify health issues, assess needs, and guide healthcare planning. This data helps in developing effective public health interventions and policies.
Choice A (To provide medical treatment to individuals) is incorrect because health surveys focus on population-level data collection, not individual treatment. Choice C (To distribute health education materials) is incorrect as the primary purpose of a health survey is data collection, not distribution of materials. Choice D (To perform laboratory tests) is incorrect because health surveys typically involve collecting information through questionnaires and interviews, rather than conducting laboratory tests.
