Which of the following is an appropriate site for administration of DPT vaccine?

Correct Answer: B

Rationale: The correct answer is B: Vastus lateralis muscle. The vastus lateralis is a recommended site for administration of DPT vaccine in infants and young children. It is a large muscle located in the thigh, providing a well-developed area for injection with minimal risk of hitting nerves or blood vessels. The site is easily accessible, especially for parents or caregivers administering the vaccine. Choice A (Deltoid muscle) is more commonly used in adults, not preferred for infants. Choices C (Gluteus maximus muscle) and D (Abdomen) are not recommended sites for DPT vaccine administration due to potential risk of hitting sciatic nerve in the gluteal region and abdominal organs in the abdomen, respectively.

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 injection site for administering the DPT vaccine to an infant is the vastus lateralis muscle. This site is preferred for infants and young children because it has a larger muscle mass, reducing the risk of hitting a nerve or bone. The vastus lateralis muscle is located on the thigh, making it easily accessible and safe for injecting vaccines. It is recommended by healthcare professionals for infants due to better absorption and reduced discomfort. In contrast, the deltoid muscle is more suitable for adults, the gluteal muscle carries a risk of hitting the sciatic nerve, and the forearm lacks sufficient muscle mass for injection.

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.

Correct Answer: A

Rationale: The correct answer is A: BCG. BCG vaccine is recommended at birth to prevent tuberculosis. It is given to protect infants from severe forms of TB. Other choices (B: Hepatitis B, C: OPV, D: Measles) are typically given at later stages as part of the routine childhood vaccination schedule. Hepatitis B vaccine is usually given within 24 hours of birth, OPV is given in multiple doses starting at 6 weeks of age, and Measles vaccine is given at around 12-15 months of age. Therefore, BCG is the recommended vaccine to be given at birth compared to the other choices.
