Why is iron supplementation given to pregnant women?

Correct Answer: A

Rationale: Iron supplementation is given to pregnant women to prevent anemia. During pregnancy, iron requirements increase to support the growing fetus and maternal blood volume expansion. Anemia in pregnancy can lead to complications such as low birth weight, preterm birth, and maternal fatigue. Iron is essential for the production of hemoglobin, which carries oxygen to the tissues. Therefore, ensuring adequate iron levels helps prevent anemia and supports the health of both the mother and the baby. Summary: - A: Correct. Prevents anemia by supporting hemoglobin production. - B: Incorrect. Fetal growth is influenced by various factors, not just iron. - C: Incorrect. Premature labor is not directly prevented by iron supplementation. - D: Incorrect. Postpartum hemorrhage is more related to factors like uterine atony, not iron levels.

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: 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: A

Rationale: The correct answer is A: BCG. BCG vaccine is administered through intradermal injection, leaving a small scar due to the immune response it triggers. The scar formation is a characteristic feature of the BCG vaccine and is used as an indicator of successful vaccination. Other vaccines like DPT, Hepatitis B, and Measles do not typically leave a permanent scar at the injection site. The scar formation with BCG vaccine is a result of the body's immune response to the live attenuated Mycobacterium bovis strain in the vaccine, leading to a localized inflammatory reaction and subsequent scarring.

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: 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: 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: Rationale: 1. Primigravida refers to a woman pregnant for the first time. 2. Colostrum is the first milk produced after childbirth, rich in antibodies and nutrients. 3. Offering the breast within 30 minutes ensures the baby receives this vital colostrum. 4. Colostrum provides immune protection and establishes the baby's gut microbiome. 5. Options A and B relate to mature milk production, not colostrum. 6. Option D focuses on practice, not the immediate benefits of colostrum.

Correct Answer: B

Rationale: The correct answer is B (4 weeks) for the minimum interval between two doses of the MMR vaccine. This interval is necessary for the body to develop a strong immune response to the vaccine components. Waiting at least 4 weeks allows the immune system to properly process and respond to the initial dose before receiving the second dose. Administering the second dose too soon may result in a weaker immune response and decreased effectiveness of the vaccine. Choices A, C, and D are incorrect as they are not in line with the recommended minimum interval for effective vaccination.
