Final answer:
High blood glucose levels in early pregnancy are associated with several congenital abnormalities, except for enhanced cognitive abilities which are not a result of high glucose but can actually be negatively impacted by other factors such as alcohol consumption during pregnancy. The correct option is 4. Enhanced cognitive abilities
Step-by-step explanation:
High blood glucose levels during the first two months of pregnancy are known to be associated with a range of congenital abnormalities in newborns. These include neural tube defects, heart defects, and limb abnormalities.
However, high glucose levels are not associated with enhanced cognitive abilities. On the contrary, factors such as alcohol consumption during pregnancy can lead to cognitive deficits and developmental delays among various other issues.
Therefore, of the options given, the one exception to the congenital abnormalities associated with high blood glucose levels in newborns is enhanced cognitive abilities.
High blood glucose levels in the first 2 months of pregnancy are associated with several congenital abnormalities in newborns, including neural tube defects, heart defects, and limb abnormalities.
However, enhanced cognitive abilities are not typically associated with high blood glucose levels in the first 2 months of pregnancy.
The correct option is 4. Enhanced cognitive abilities
