During the first trimester, which sign should the nurse expect to see as documented by the healthcare provider?

Hegar's sign is a significant indicator of early pregnancy that can be detected during the first trimester. It refers to the softening of the lower uterine segment, which occurs as the body adapts to the growing fetus. This sign is typically observed during a pelvic examination performed by a healthcare provider and is generally noticeable around the 6th to 8th week of gestation.

In contrast, other signs such as fetal heartbeat detection typically may not be confirmed until around 10 to 12 weeks into the pregnancy, making them less relevant during the very early stages. Quickening, which is the first time a mother feels fetal movements, generally occurs later in pregnancy, usually between 16 and 25 weeks. Similarly, fetal movement felt by the mother occurs even later as the fetus grows stronger and more active. Therefore, among the options listed, Hegar's sign is the most appropriate and earliest indication that aligns with the timeline of the first trimester.
