A nurse is counseling a woman about prenatal vitamins and focuses on the need for folic acid intake. Which disorder is a potential consequence of inadequate folic acid intake?
Down syndrome
Cerebral palsy
Neurofibromatosis
Spina bifida
The Correct Answer is D
Spina bifida is a birth defect that occurs when the neural tube, which forms the brain and spinal cord, does not close properly during early fetal development. This can result in an opening in the spine that exposes the spinal cord and nerves, leading to various complications such as paralysis, bladder and bowel problems, hydrocephalus, and learning difficulties. Folic acid is a B vitamin that is essential for the formation of the neural tube and other organs in the embryo. Inadequate folic acid intake before and during pregnancy can increase the risk of spina bifida and other neural tube defects.

Naïve T cells are a type of white blood cell that has not encountered a specific antigen before and are ready to respond to new infections. As people age, the number of naïve T cells decreases due to the shrinking of the thymus gland, which produces and matures T cells. This reduces the ability of the immune system to recognize and fight new pathogens and lowers the effectiveness of vaccines.
