What is a potential consequence of high maternal glucose levels during labor?

High maternal glucose levels during labor can significantly impact fetal health, particularly influencing the fetal heart rate patterns. Elevated glucose levels can lead to a condition known as fetal hyperglycemia, which may result in increased fetal stress. This stress can manifest as abnormal heart rate patterns, such as variable decelerations or other signs of fetal distress.

In contrast to the correct choice, the other outcomes listed do not accurately represent the effects of high glucose levels. For instance, stabilization of fetal heart rates or experiencing normal heart patterns without effect does not align with the physiological response often observed in response to elevated maternal glucose, indicating that such stable conditions are unlikely. Furthermore, while fetal weight may be influenced by maternal glucose levels, simply stating an increase in fetal weight does not capture the more immediate and relevant concern of altered heart rate patterns during labor. Thus, the correct response emphasizes the significant risks associated with abnormal heart rate patterns in the context of high maternal glucose levels.
