Correct Answer: A

Rationale: The correct answer is A: RA 8483. This law specifically established the Philippine Institute of Traditional and Alternative Health Care. RA 4823, RA 2483, and RA 3482 are incorrect as they do not pertain to the creation of this institute. RA 4823 is about the Agricultural Land Reform Code, RA 2483 is about the Philippine Medical Care Commission, and RA 3482 is about the Philippine Medical Association. Therefore, based on the specific content of each law, A is the correct choice for the creation of the Philippine Institute of Traditional and Alternative Health Care.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Yin represents yielding, negative, and feminine energy in traditional Chinese medicine. 2. It is associated with qualities like darkness, coldness, and rest. 3. Yin balances the opposing force of Yang in the body. 4. In TCM, maintaining a balance between Yin and Yang is crucial for overall health. 5. Therefore, the correct answer is A: Yin. Summary: - Choice B (Yang) is incorrect as it represents the opposite force to Yin. - Choice C (Qi) is incorrect as it refers to the vital energy flow in TCM. - Choice D (Chai) is incorrect as it is not a term used in traditional Chinese medicine.

Correct Answer: B

Rationale: The correct answer is B: Letter of Instruction No. 949. This document issued by the Philippine government in 1979 officially adopted the Primary Health Care (PHC) approach. It outlined the strategies and framework for implementing PHC nationwide. The Alma Ata Declaration on PHC (A) is a global agreement but not the legal basis in the Philippines. Presidential Decree No. 147 (C) and Presidential Decree No. 996 (D) do not specifically address the PHC approach. Therefore, the legal basis for PHC in the Philippines is Letter of Instruction No. 949.

Correct Answer: D

Rationale: The correct answer is D because it exemplifies intersectoral linkages by showcasing collaboration between different sectors (public health and education). This cooperation enables sharing of resources, expertise, and information to address broader community health needs. Choice A focuses on a single-sector referral system, Choice B emphasizes teamwork within the same sector, and Choice C highlights endorsement within a specific profession, all lacking the cross-sector collaboration seen in Choice D.
