Which of the following is a benefit of exclusive breastfeeding?

Correct Answer: C

Rationale: Exclusive breastfeeding provides complete nutrition for the first 6 months of a baby's life as breast milk contains all necessary nutrients. This is crucial for infant growth and development. It is recommended by health organizations worldwide. Other choices are incorrect: A is not directly related to breastfeeding, B is false as breastfeeding actually helps reduce allergies, and D is not a primary benefit of exclusive breastfeeding.

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: B

Rationale: The correct answer is B: Reduces the risk of severe measles. Vitamin A helps strengthen the immune system, reducing the severity of infections like measles. Providing supplements can prevent complications and reduce mortality rates. A, C, and D are incorrect as Vitamin A specifically targets measles prevention, not cognitive development, anemia prevention, or physical growth. Measles is a major concern in children, and Vitamin A supplementation significantly benefits their health by reducing measles-related complications.

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: C

Rationale: The primary purpose of administering Vitamin K to newborns is to prevent bleeding disorders. Vitamin K is essential for the production of blood clotting factors, which helps prevent excessive bleeding. Newborns are born with low levels of Vitamin K, putting them at risk for bleeding disorders like vitamin K deficiency bleeding. Administering Vitamin K at birth helps ensure proper blood clotting function. The other choices are incorrect because Vitamin K does not directly prevent infection, promote growth, or enhance immune function in newborns.
