What is a common characteristic of the fundus during pregnancy?

The characteristic of the fundus during pregnancy that is correctly identified is that it is firm and boardlike. As the pregnancy progresses, the uterine muscle fibers grow and become stronger to accommodate the developing fetus, leading to a firm structural support. This firm consistency is also a result of the increased blood flow and hormonal changes that promote muscle tone in the uterus.

In early pregnancy, the fundus can be softer due to the body preparing for expansion, but as the pregnancy progresses, especially in the second and third trimesters, it becomes firmer. A firm and boardlike fundus indicates that the uterus is healthy and functioning effectively to maintain pregnancy.

The other options do not accurately describe the fundal consistency during pregnancy. A soft and easily indented fundus would indicate potential complications, such as a lack of tone or insufficient muscle strength, which is not typical in a healthy pregnancy. Highly elastic and stretchable refers more to the overall capacity of the uterus as it grows, rather than the palpation characteristics of the fundus at any given moment. A rough and irregular surface is also not a characteristic of the fundus; the surface should be smooth as it prepares for the delivery process.
