What is the recommended duration of exclusive breastfeeding?

Correct Answer: B

Rationale: The recommended duration of exclusive breastfeeding is 6 months. This is because breast milk provides all the necessary nutrients for an infant's growth and development in the first 6 months of life. Introducing solid foods too early can increase the risk of infections and allergies. Choice A (3 months) is not ideal as it may not provide sufficient nutrients for the baby's growth. Choices C (9 months) and D (12 months) exceed the recommended duration and may not be necessary for exclusive breastfeeding, as other foods can be introduced after 6 months.

Correct Answer: C

Rationale: The correct answer is C: Breast milk. Breast milk is the best type of milk for infants below 6 months of age because it provides the ideal nutrition and antibodies necessary for their growth and development. It contains the perfect balance of nutrients, is easily digestible, and helps protect infants from infections and diseases. Choice A: Cow's milk is not recommended for infants below 6 months as it is difficult for them to digest and lacks essential nutrients like iron and vitamin E. Choice B: Goat's milk is also not recommended for infants below 6 months as it lacks certain nutrients and may cause allergic reactions. Choice D: Soy milk is not suitable as a primary source of nutrition for infants below 6 months as it may not provide all the necessary nutrients and can lead to digestive issues. In summary, breast milk is the best choice for infants below 6 months due to its unique composition and numerous benefits compared to other types of milk.

Correct Answer: B

Rationale: The correct answer is B: To boost the immune system. Vitamin A is essential for maintaining a healthy immune system by supporting the production and function of white blood cells. This helps the body fight off infections and illnesses. Administering Vitamin A to children can help prevent deficiencies and strengthen their immune response. Explanation of why the other choices are incorrect: A: Vitamin D is more closely associated with improving bone health, not Vitamin A. C: Cognitive development is primarily influenced by nutrients like iron and omega-3 fatty acids, rather than Vitamin A. D: Anemia is usually prevented by iron supplementation, not Vitamin A.

Correct Answer: B

Rationale: The correct answer is B: Sunken fontanelle. Dehydration in infants can cause the fontanelle, the soft spot on the baby's head, to appear sunken. This is due to decreased fluid levels in the body. Sunken fontanelle is a common and easily identifiable sign of dehydration in infants. The other choices are incorrect because frequent urination is not typically associated with dehydration in infants, excessive drooling can be a normal part of teething, and increased appetite is not a specific sign of dehydration in infants.

Correct Answer: C

Rationale: The correct answer is C: Folic acid. Folic acid is critical for preventing neural tube defects as it is essential for proper development of the neural tube in the fetus. It helps in the formation of the baby's brain and spinal cord. Iron (A) is important for preventing anemia, not neural tube defects. Calcium (B) is crucial for bone health but not directly related to neural tube development. Vitamin D (D) is important for calcium absorption, but not specifically for preventing neural tube defects. Overall, folic acid stands out as the most critical nutrient for this purpose.
