What is typically observed in a pregnancy exam at 28 weeks?

At around 28 weeks of pregnancy, it is typical for the fundus, which is the top part of the uterus, to be found above the level of the umbilicus. This corresponds to the time when the uterus is expanding significantly to accommodate the growing fetus. By the third trimester, the fundal height measurement is an important indicator of fetal growth and development.

In a healthy pregnancy, around 28 weeks, the fundus is expected to reach approximately 2 to 3 centimeters above the umbilicus. This indicates that the pregnancy is progressing normally, as the uterus continues to rise and expand throughout the latter stages of gestation.

In contrast, the other options do not align with typical findings at this stage of pregnancy. The fundus being at the pubic symphysis or at the level of the umbilicus would be more characteristic of earlier in the pregnancy, while the fundus below the pubic symphysis would indicate a potential issue, as the uterus would be much smaller than expected at this advanced gestational age. Thus, the observation of the fundus being above the umbilicus at 28 weeks is a key marker of proper fetal development and gestational progress.
