What physiological change should a nurse expect in a client during labor?

During labor, a client experiences a variety of physiological changes due to the body’s response to the stress of labor and the release of various hormones. One significant change is the increase in the body's energy expenditure, which includes mobilizing glucose for energy during contractions. This can lead to a decrease in blood glucose levels as the body utilizes stored glucose to meet the heightened energy demands.

As the mother’s body works harder during labor, especially in the presence of pain and stress, insulin sensitivity may also increase, which can further lower blood glucose levels. This adjustment is a normal response as the body prioritizes energy use for the labor process. Monitoring blood glucose levels during labor is important, particularly for clients with a history of diabetes or gestational diabetes, to ensure they remain within a safe range.

The other options presented do not align with the expected physiological changes during labor. An increase in appetite is typically not seen, as many clients may experience nausea or lack of interest in food during this stressful time. An increase in heart rate does occur, but it is generally a response to pain or stress rather than a consistent physiological change. Stabilization of blood pressure can be misleading as well, since blood pressure may fluctuate due to pain, anxiety, and other factors during labor
