Which numerator is used in computing the general fertility rate?

Correct Answer: B

Rationale: The correct answer is B: Number of registered live births. The general fertility rate is calculated by dividing the number of live births in a specific period by the total number of women of reproductive age during that period. This numerator reflects the actual occurrence of live births in the population, making it the most appropriate measure for determining fertility rates accurately. A: Estimated midyear population is not used as the numerator because it does not directly measure fertility rates. C: Number of pregnancies in the year includes all pregnancies, not just live births, which would overestimate the fertility rate. D: Number of females of reproductive age is not used as the numerator as it represents the total population, not the specific group giving birth.

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: 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: Retinol 200,000 IU. Retinol in high doses can cause birth defects in a developing fetus. Pregnant women should avoid excessive vitamin A intake to prevent harm to the baby. Tetanus toxoid (A), ferrous sulfate (C), and potassium iodate (D) are safe and recommended for pregnant women to support their health and the baby's development. In summary, retinol 200,000 IU is contraindicated due to the potential for birth defects, while the other choices are safe and beneficial during pregnancy.

Correct Answer: A

Rationale: The correct interval between tetanus toxoid doses for pregnant women is 4 weeks. This short interval ensures optimal immunity for both the mother and the baby against tetanus. Giving the dose every 4 weeks during pregnancy helps maintain the protective levels of antibodies. Waiting longer intervals could decrease the effectiveness of the vaccine and leave the mother and baby vulnerable to tetanus infection. Choices B, C, and D are incorrect because longer intervals between doses may not provide adequate protection and could compromise immunity levels during pregnancy.

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: Vastus lateralis muscle. The vastus lateralis is a recommended site for administration of DPT vaccine in infants and young children. It is a large muscle located in the thigh, providing a well-developed area for injection with minimal risk of hitting nerves or blood vessels. The site is easily accessible, especially for parents or caregivers administering the vaccine. Choice A (Deltoid muscle) is more commonly used in adults, not preferred for infants. Choices C (Gluteus maximus muscle) and D (Abdomen) are not recommended sites for DPT vaccine administration due to potential risk of hitting sciatic nerve in the gluteal region and abdominal organs in the abdomen, respectively.

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: 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.
