In the census of the Philippines in 1995, there were about 35,299,000 males and about 34,968,000 females. What is the sex ratio?

Correct Answer: B

Rationale: The sex ratio is calculated by dividing the number of males by the number of females and multiplying by 100. In this case, (35,299,000 / 34,968,000) x 100 = 100.94:100. This means for every 100 females, there are 100.94 males, indicating a slightly higher number of males. Choice A (99.06:100) is incorrect as it suggests fewer males than females, which is not the case. Choice C (50.23%) and choice D (49.76%) are incorrect as they represent percentages rather than ratios, leading to a misleading interpretation of the data.

Correct Answer: B

Rationale: The correct answer is B: Liver cancer. The Hepatitis B vaccine prevents Hepatitis B infection, which is a major cause of chronic liver disease and can lead to liver cancer. Jaundice (choice A) is a symptom of Hepatitis B infection, not a disease prevented by the vaccine. Pneumonia (choice C) and Tuberculosis (choice D) are both respiratory infections and are not prevented by the Hepatitis B vaccine. The key is to understand the specific disease targeted by the vaccine and its related health outcomes.

Correct Answer: C

Rationale: The correct answer is C: Magnitude of the health problem. In community health care, prioritizing based on the magnitude of the health problem is crucial as it helps identify issues affecting a large number of individuals. By addressing high-impact problems first, resources can be maximized to benefit the community as a whole. Modifiability (A) is important but not unique to community health. Nature of the problem (B) can vary and may not always indicate priority. Preventive potential (D) is valuable but does not solely determine priority in community health care.

Correct Answer: C

Rationale: The correct answer is C: De facto. This method assigns individuals to a specific location based on where they are physically located during the census. "De facto" means "in fact" or "in reality." This ensures accurate representation of the population in a specific area at the time of the census. A: De jure refers to assignment based on legal residence, not necessarily physical location. B: De locus is not a standard term in census methodology. D: De novo means "from the beginning" and is not relevant to population assignment in a census.

Correct Answer: D

Rationale: The correct answer is D, as it highlights the sustainability aspect crucial in primary health care. Sustainable health programs align with the community's development level, ensuring long-term effectiveness. A: Providing free health services is not an indicator of success as sustainability and community involvement are key. B: While empowering local officials is important, it doesn't directly measure the success of the primary health care approach. C: Providing care based on identified needs is a fundamental aspect but doesn't guarantee success without sustainability.

Correct Answer: A

Rationale: The correct answer is A: Tally report. In the FHSIS, the monthly field health service activity report is used to tally and summarize the health services provided within a specific period. It helps track the number of services rendered and monitor performance indicators. The other choices are incorrect because: B: Output report usually presents processed data in a structured format. C: Target/client list is a list of clients or individuals targeted for specific health services. D: Individual health record contains detailed health information of a specific individual, not a summary of services provided. In conclusion, the monthly field health service activity report in FHSIS is specifically designed for tallying and summarizing service activities, making option A the correct choice.

Correct Answer: B

Rationale: The correct answer is B: Vitamin A. During measles, Vitamin A supplementation is crucial to reduce the risk of complications and improve recovery. Vitamin A deficiency is common in children with measles and can lead to severe outcomes. Tetanus toxoid (A) is not indicated in measles treatment. Vitamin D (C) and Vitamin E (D) do not play a significant role in managing measles symptoms. In summary, Vitamin A is essential for children with measles to prevent complications and support recovery, making it the correct choice among the options provided.

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: C

Rationale: The correct answer is C: Folic Acid. Folic Acid deficiency during pregnancy is associated with an increased risk of neural tube defects in the developing fetus. Folic acid is crucial for proper neural tube formation in early pregnancy. Niacin (A), Riboflavin (B), and Thiamine (D) deficiencies do not directly impact neural tube development. Niacin is important for energy production, riboflavin for cell growth and function, and thiamine for nerve function, but they do not specifically affect neural tube closure like folic acid does.
