Correct Answer is D

Explanation

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.

A. pH 7.5 and PaCO2 32 mm Hg B. pH 6.5 and PaCO2 40 mm Hg C. pH 6.5 and PaCO2 32 mm Hg D. pH 7.5 and PaCO2 40 mm Hg

Correct Answer is A

Explanation

Respiratory alkalosis is a condition where the blood's pH is elevated due to excessive removal of CO2 from the body. This can occur when the breathing rate is too fast or deep, such as in response to hypoxia, anxiety, fever, or lung disease. When CO2 is removed from the blood, less H2CO3 is formed, which raises the blood's pH by decreasing the concentration of H+ and HCO3- . A normal blood pH is between 7.35 and 7.45, and a normal partial pressure of arterial carbon dioxide (PaCO2) is between 35- and 45 mm Hg. Therefore, a patient with respiratory alkalosis would have a higher-than-normal pH and a lower-than-normal PaCO2.
