Correct Answer: C

Rationale: The correct answer is C, RA 7160. This law, also known as the Local Government Code, decentralizes health services to local government units. RA 7035 is not the legal basis for decentralizing basic health services. EO 119 and PD 999 are also not the correct legal bases for the decentralization of health services.

Correct Answer: A

Rationale: The correct immediate action after recovering an avulsed tooth is to rinse it with water and place it back in the socket. This helps preserve the tooth and increases the chances of successful re-implantation. Placing the tooth in a clean plastic bag for transport to the dentist (choice B) is not ideal as immediate re-implantation is preferred. Holding the tooth by the roots until reaching the emergency room (choice C) can further damage the tooth. Asking the child to replace the tooth even if bleeding continues (choice D) is incorrect and may lead to improper re-implantation.

Correct Answer: D

Rationale: The correct answer is to identify myths and misconceptions prevailing in the community and their sources. This is the initial step in addressing misconceptions effectively. By understanding the specific myths and where they originate from, a health educator can tailor their approach to correct these misconceptions. Choice A is incorrect because while influential leaders can play a role, identifying myths comes first. Choice B is incorrect as selecting an approach should come after understanding the myths. Choice C is incorrect as deciding who will be involved in a conference is not the primary step in combating myths and misconceptions.

Correct Answer: A

Rationale: In the case of a child with under-nutrition and diarrhea, advising the mother to give milk and juices between meals at home is the appropriate action. This helps address the nutritional needs of the child while also providing hydration. Option B, giving nutritious food available at home, may not be sufficient in addressing immediate needs such as dehydration. Option C, referring to the hospital, may be necessary in severe cases but is not the first-line action. Option D, providing ORS solution, is important but does not directly address the under-nutrition concern.

Correct Answer: A

Rationale: Corrected Rationale: Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations and the application of this study to the control of health problems. It focuses on identifying and understanding the factors that influence the occurrence and distribution of diseases, defects, disability, or death of groups of individuals. Therefore, the correct answer is A. Choice B, vital health statistics, is not the primary focus of epidemiology. While vital health statistics may be used in epidemiological studies, it is not the direct concern of epidemiology. Choice C, environmental sanitation, although important for public health, is not the main focus of epidemiology. Epidemiology is more concerned with the factors influencing disease occurrence and distribution, rather than environmental sanitation. Choice D, treatment of a communicable disease, is more related to clinical medicine rather than epidemiology. Epidemiology is more focused on prevention, control, and understanding the patterns and causes of diseases rather than their treatment.
