Knowing that malnutrition is a common community health issue, you decided to conduct a nutritional assessment. What population is particularly vulnerable to protein-energy malnutrition (PEM)?

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: 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 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: A

Rationale: The correct answer is A. The OB score G5P3 means the client has had 5 pregnancies with 3 live births. This indicates a history of multiple pregnancies and deliveries, suggesting a higher risk for complications during labor. This would disqualify her for a home delivery due to the increased potential for obstetric emergencies. Explanation for why the other choices are incorrect: - B: Palmar pallor may indicate anemia but can be managed in a hospital setting. - C: Blood pressure of 130/80 is within normal range and does not necessarily disqualify her for a home delivery. - D: Cephalic presentation means the baby's head is down, which is a favorable position for delivery and does not disqualify her for a home birth.

Correct Answer: A

Rationale: The correct answer is A: To prevent anemia. Iron supplementation in pregnant women is primarily aimed at preventing iron-deficiency anemia, a common condition during pregnancy due to increased demand for iron. Anemia can lead to complications for both the mother and the fetus, such as low birth weight and preterm birth. Providing iron helps maintain adequate hemoglobin levels for optimal oxygen transport. Summary of why other choices are incorrect: B: Supporting fetal growth is an important aspect of prenatal care, but iron supplementation specifically targets preventing anemia. C: While iron deficiency may contribute to premature labor, the primary purpose of iron supplementation is to prevent anemia. D: Postpartum hemorrhage risk is more related to factors such as uterine atony and trauma during childbirth, not directly impacted by iron supplementation.

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: 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: Post-natal care. Post-natal care refers to the care given to a woman within a month after delivering a baby. This care is crucial for monitoring the mother's physical and emotional health, providing support with breastfeeding, ensuring proper healing, and addressing any postpartum complications. Follow-up care (A) is a general term that may include various types of care beyond the immediate post-natal period. Maternity care (B) typically refers to the care provided during pregnancy and childbirth, not specifically after delivery. Puerperal care (C) specifically focuses on the period immediately following childbirth and may not encompass the entire month post-delivery.

Correct Answer: B

Rationale: The most suitable method for collecting data in this scenario is a survey (Choice B). Here's the rationale: 1. Surveys allow for direct interaction with families to gather specific information on PEM. 2. Surveys can be tailored to ask targeted questions related to nutritional status. 3. Surveys provide a structured approach to collecting data from a sample of families. 4. Census (Choice A) collects data from the entire population, not just the target group. 5. Record review (Choice C) may not capture current or specific details on PEM. 6. Review of civil registry (Choice D) focuses on demographic data, not specific nutritional information.
