Estimate the number of pregnant women who will be given tetanus toxoid during an immunization outreach activity in a barangay with a population of about 1,500.

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: A

Rationale: The correct answer is A: Crude birth rate. Natality rate refers to the number of live births per 1,000 people in a population per year. The crude birth rate includes all live births in a population without any adjustments. B: Neonatal mortality rate measures the number of deaths within the first 28 days of life per 1,000 live births. C: Infant mortality rate measures the number of deaths within the first year of life per 1,000 live births. D: General fertility rate measures the number of live births per 1,000 women of childbearing age.

Correct Answer: B

Rationale: To calculate the crude death rate, divide the total number of deaths by the total population and then multiply by 1000. In this case, 94 deaths out of 18,000 population is (94/18000)*1000 = 5.2/1000. This is the correct answer (B). Choice A (4.1/1000) is incorrect as it underestimates the death rate. Choice C (6.3/1000) and D (7.3/1000) are both overestimations of the death rate based on the given data.

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: C

Rationale: The correct answer is C: Swaroop's index. This index considers the age distribution of deaths, providing a more accurate reflection of the health status of a community compared to other statistics. A focuses on a specific age group, limiting the scope. B solely focuses on infant deaths, ignoring other age groups. D is a basic measure that doesn't consider age distribution, leading to potential inaccuracies in reflecting the overall health status of the community. Swaroop's index is a comprehensive indicator that considers all age groups, making it the most accurate choice for assessing the health status of a community.
