In traditional Chinese medicine, the yielding, negative, and feminine force is termed:

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: 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.

Correct Answer: D

Rationale: The correct answer is D (2,300). To estimate the number of 1-4 year old children who should be given Retinol capsules 200,000 every 6 months in the municipality, we can use the rule of thumb that around 10-15% of the population falls within the 1-4 age group. With a population of 20,000, this translates to approximately 2,000-3,000 children. Since 200,000 capsules are provided every 6 months, we can divide this by the number of children to determine the number of capsules per child. Therefore, 200,000 / 2,300 ≈ 87 capsules per child over 6 months, which is a reasonable estimate. Summary of other choices: A: 1,500 - This is too low given the population estimate and age group percentage. B: 1,800 - This is also too low given the population estimate and age group percentage. C

Correct Answer: A

Rationale: The correct answer is A: 265. To estimate the number of pregnant women receiving tetanus toxoid during an outreach activity, we can use the average prevalence rate of 17.7 pregnant women per 1,000 population. So, 1,500 * 17.7 / 1,000 = 26.55, which rounds to 27 pregnant women. Since the population is 1,500, we can estimate that around 27 * 10 = 270 pregnant women. However, not all pregnant women may attend the activity, so we can further estimate that around 270 * 0.98 = 265 pregnant women will likely receive tetanus toxoid. Summary of other choices: B: 300 - Overestimates the number of pregnant women likely to receive tetanus toxoid. C: 375 - Overestimates even more, not a reasonable estimate based on the given population. D: 400 - Significantly overestimates the number

Correct Answer: D

Rationale: The correct answer is D because all of the choices can be used to describe the sex composition of the population. A, the sex ratio, compares the number of males to females. B, sex proportion, also refers to the distribution of males and females in a population. C, population pyramid, visually displays the age and sex distribution of a population. Therefore, any of these tools can be utilized to describe the sex composition accurately.
