Rationale: Community health nurses are primarily responsible for coordinating emergency response efforts during disasters. This involves organizing and implementing strategies to address the health needs of the community in crisis situations. Providing direct patient care (Choice A) is often carried out by other healthcare professionals such as doctors and paramedics during disasters. Conducting research on disaster impacts (Choice B) is important for understanding the effects of disasters but is not the primary role of a community health nurse. Developing new healthcare policies (Choice D) is typically the responsibility of policymakers and public health officials rather than community health nurses.

Choice C is incorrect as educating teenagers about condom use is a primary prevention strategy to prevent the initial occurrence of STDs rather than intervening after exposure, making it a primary, not a secondary prevention strategy. Choice D is incorrect as there is a valid example of a secondary prevention strategy provided in choice A.
