What key nutrients does a fetus need during the third stage of pregnancy for blood and bone development?

• A. Vitamin C, Protein, Calcium
• B. Calcium, Nitrogen, Iron
• C. Folate, Magnesium, Zinc
• D. Iron, Fiber, Potassium

Answer: (B)

For blood and bone development during the third stage of pregnancy, the correct nutrients are calcium and iron. Calcium plays a crucial role in the development of the fetal bones and teeth, which are essential for the structural integrity and function as the fetus grows. Iron is vital for the formation of hemoglobin in red blood cells, which is important for transporting oxygen to both the mother and the developing fetus. While nitrogen does play a role in the body, particularly in building proteins, it is not commonly listed as a key nutrient in the context of pregnancy. In contrast, the other options contain nutrients that, while important for various health reasons, do not specifically target the critical needs for blood and bone development during this stage. Therefore, focusing on calcium and iron aligns best with the physiological requirements of a developing fetus during that period.
