Which of the following is an essential nutrient required for preventing neural tube defects?

Correct Answer: D

Rationale: The correct answer is D: Folic acid. Folic acid is essential for preventing neural tube defects because it plays a crucial role in DNA synthesis and cell division, particularly during early fetal development. Adequate folic acid intake before and during pregnancy can significantly reduce the risk of neural tube defects. Iron (A), Vitamin C (B), and Calcium (C) are important nutrients for overall health but do not have a direct role in preventing neural tube defects. Iron is vital for red blood cell production, Vitamin C is an antioxidant that supports the immune system, and Calcium is essential for bone health. However, for preventing neural tube defects specifically, folic acid is the essential nutrient.

Correct Answer: C

Rationale: The correct answer is C: Iron. Iron is essential for preventing anemia in pregnant women because it is a key component of hemoglobin, the protein in red blood cells that carries oxygen to tissues and organs. During pregnancy, the demand for iron increases to support the growing fetus and the mother's increased blood volume. Without adequate iron intake, pregnant women are at a higher risk of developing iron-deficiency anemia, which can lead to complications for both the mother and the baby. Other choices are incorrect because: A: Vitamin C is important for iron absorption but does not directly prevent anemia. B: Vitamin D is important for bone health but does not prevent anemia. D: Calcium is important for bone health but does not prevent anemia in pregnant women.

Correct Answer: B

Rationale: The correct action is to delay the immunization until the fever subsides. This is because administering a vaccine during a fever may affect the body's immune response and efficacy of the vaccine. Giving a lower dose (choice C) may not provide adequate protection. Administering an antipyretic (choice D) may temporarily reduce fever but does not address the underlying illness causing the fever. Administering the vaccine as scheduled (choice A) can be harmful and is not recommended when the child has a fever.

Correct Answer: A

Rationale: The correct answer is A: Early detection of pregnancy complications. Antenatal care involves regular check-ups during pregnancy to monitor the health of both the mother and the baby. Early detection of pregnancy complications through antenatal care allows for timely intervention and management, reducing the risks to both the mother and the baby. This can help prevent serious complications and improve outcomes. Incorrect choices: B: Increased risk of preterm labor - Antenatal care aims to reduce the risk of preterm labor through monitoring and appropriate management. C: Decreased maternal weight gain - Antenatal care focuses on ensuring appropriate weight gain for a healthy pregnancy. D: Delayed fetal growth - Antenatal care helps monitor fetal growth and detect any issues early to prevent delayed growth.

Correct Answer: B

Rationale: The correct answer is B: Children aged 1-4 years. This age group is most vulnerable to PEM due to their rapid growth and development, high energy requirements, and dependency on caregivers for nutrition. Infants below 6 months are typically protected by breast milk, adolescents have lower risk due to fewer growth demands, and elderly are more at risk for other types of malnutrition. Therefore, children aged 1-4 years are the most vulnerable to PEM.

Correct Answer: D

Rationale: The correct answer is D: Focusing solely on curative care. The Maternal and Child Health (MCH) program aims to prevent illness and promote health in pregnant women, mothers, infants, and children. Focusing solely on curative care does not align with the preventive and promotive goals of the MCH program. Reducing infant mortality, improving maternal health, and providing family planning services are integral components of the MCH program that aim to enhance the overall well-being of mothers and children. By emphasizing prevention and health promotion, the MCH program aims to address the root causes of health issues rather than solely focusing on treating illnesses after they occur.

Correct Answer: B

Rationale: The correct answer is B: 6 months. Exclusive breastfeeding is recommended by WHO for the first 6 months of a baby's life. This is because breast milk provides all the essential nutrients and antibodies needed for a baby's optimal growth and development during this critical period. Introducing other foods or liquids before 6 months can increase the risk of infections and allergies in infants. Choices A, C, and D are incorrect because they do not align with the WHO guidelines for exclusive breastfeeding duration.

Correct Answer: B

Rationale: The correct answer is B: Improving access to high-quality immunization services. GIVS aims to ensure that everyone has access to vaccines and immunization services to prevent vaccine-preventable diseases. This objective aligns with the overall goal of increasing vaccination coverage and reducing the burden of vaccine-preventable illnesses globally. Choice A is incorrect as GIVS focuses on communicable diseases, not non-communicable diseases. Choice C is incorrect as GIVS aims to improve access to immunization services, not necessarily reduce the cost of healthcare. Choice D is incorrect as GIVS does not specifically target increasing the number of healthcare professionals, but rather improving access to immunization services.

Correct Answer: C

Rationale: The correct answer is C because a community health nurse focuses on promoting health and preventing disease within the community through education, advocacy, and preventive care. This role involves working with individuals, families, and communities to improve overall health outcomes. A: Providing acute care in hospitals is incorrect as this is typically the role of hospital nurses, not community health nurses. B: Conducting surgeries is incorrect as this is a task performed by surgeons or operating room nurses, not community health nurses. D: Diagnosing and treating medical conditions is incorrect as this falls under the responsibility of healthcare providers such as physicians or nurse practitioners, not community health nurses.
