At 10 weeks pregnant, which presumptive sign of pregnancy is a client most likely to experience?

At 10 weeks pregnant, breast changes are commonly experienced by individuals due to hormonal fluctuations, particularly the increase in estrogen and progesterone. These changes may manifest as breast tenderness, enlargement, and sensitivity. Such physical alterations occur early in pregnancy as the body prepares for potential breastfeeding and supports the developing fetus.

In the context of other options, weight gain typically does not begin until later in the first trimester or into the second trimester and is not considered a presumptive sign of pregnancy at this early stage. Nausea and vomiting, often referred to as morning sickness, can occur around this time, but it is more variable among individuals. A positive pregnancy test is a probable sign of pregnancy but is not categorized as a presumptive sign. Thus, breast changes are the most characteristic presumptive sign experienced around 10 weeks of gestation.
