Which demographic tool may be used to describe the sex composition of the population?

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.

Correct Answer: B

Rationale: The correct answer is B, under 5-year-old children. They are particularly vulnerable to protein-energy malnutrition (PEM) due to their high nutritional needs for growth and development. Infants and young children have limited food intake capacity and are dependent on caregivers for proper nutrition. This age group is at a critical stage of growth, making them more susceptible to the negative impact of malnutrition on physical and cognitive development. Pregnant women and the elderly (choice A) have specific nutritional needs but are not as vulnerable to PEM as young children. Choices C and D are incorrect as 1-4-year-old children and school-age children have a lower risk of PEM compared to under 5-year-old children.

Correct Answer: A

Rationale: The correct answer is A: 1-4 year old age-specific mortality rate. This statistic reflects the overall health and nutritional status of a population by focusing on a specific age group vulnerable to malnutrition-related issues. It provides a comprehensive view of the impact of nutrition on child health and development. Proportionate mortality rate (B) measures the distribution of causes of death, not specifically related to nutrition. Infant mortality rate (C) focuses on deaths within the first year of life, which may not fully capture the nutritional status of the whole population. Swaroop's index (D) assesses life expectancy and income level, but does not directly measure nutritional status.

Correct Answer: B

Rationale: The correct answer is B: OPV. The oral polio vaccine (OPV) used in the Expanded Program on Immunization (EPI) is stored in the freezer to maintain its potency. OPV is a live vaccine that requires cold storage to prevent the virus from becoming inactive. DPT, Hepatitis B vaccine, and Measles vaccine are typically stored in the refrigerator, not the freezer, as they are either killed or attenuated vaccines that remain stable at higher temperatures. Therefore, the need for freezer storage specifically points to OPV as the correct answer.

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: 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: C

Rationale: The correct answer is C: Smallpox. In 1980, the World Health Organization declared the Philippines and other countries in the Western Pacific Region 'free' of smallpox due to successful global vaccination campaigns. Smallpox is caused by the variola virus and is characterized by a distinctive rash. The other choices are incorrect because: A: Pneumonic plague is a severe form of the bubonic plague caused by the bacterium Yersinia pestis. B: Poliomyelitis is a viral infection that can lead to paralysis, but it was not eradicated in 1980. D: Anthrax is a bacterial infection that primarily affects animals but can also infect humans.

Correct Answer: A

Rationale: The correct answer is A: To help strengthen her immune system. Vitamin A plays a crucial role in maintaining a healthy immune system, which is especially important for postpartum women to prevent infections. Vitamin A deficiency can weaken the immune response, making the body more susceptible to infections. Explanation for other choices: B: To improve her vision - While vitamin A is essential for good vision, it is not the primary reason for administering it to a postpartum client. C: To protect her from infection - This is partially correct, as vitamin A helps protect against infections, but the primary reason is to strengthen the immune system. D: To promote wound healing - Vitamin A is important for wound healing, but the immune system support is the key reason for administering it in the postpartum period.

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.
