Final answer:
Vitamin D deficiency should be considered when a child has easy fractures in the metaphysis of bones, as it leads to rickets, a condition that causes softening of the bones and increased susceptibility to fractures.
Step-by-step explanation:
When a child experiences easy fractures in the metaphysis of bones, the vitamin deficiency that should be considered is Vitamin D deficiency. This condition, known as rickets, is characterized by the softening and weakening of bones in children, which can lead to improper bone development and increased susceptibility to fractures. The metaphysis, being the growth plate region of the bones, is particularly impacted by this disorder. Rickets is primarily caused by a deficiency in Vitamin D, which is crucial for the absorption of calcium and phosphate, the building blocks necessary for strong bones.
Vitamin D stimulates the intestinal absorption of calcium and phosphate, so when there is a deficiency, these minerals cannot be adequately absorbed, leading to calcium depletion from the bones. As a result, children with rickets may have bones that are more fragile and prone to fracturing, even with minimal trauma. Ensuring adequate intake of Vitamin D, either through diet, supplements, or sunlight exposure, is essential for preventing rickets and maintaining healthy bone development in children.
