What is a common sign that should prompt further evaluation in a client at 15 weeks gestation?

Unexplained bleeding during dental care is a common sign that warrants further evaluation in a client at 15 weeks gestation. During pregnancy, any signs of bleeding can be particularly concerning, as they may indicate complications such as placental issues or preterm labor. Dental care can sometimes provoke bleeding due to hormonal changes that increase vascularity in the gums, but unexplained bleeding should always be assessed to rule out any serious underlying conditions.

In contrast, normal weight gain and healthy vital signs do not typically signal a need for further concern. This indicates that the pregnancy is progressing well, and therefore, no additional evaluation is necessary in this instance. Similarly, headaches that resolve with acetaminophen are often considered a common discomfort in pregnancy and may not be a sign of a serious issue, particularly if they are relieved with medication. Increased vomiting or nausea can be common in the first and early second trimesters of pregnancy; however, if this becomes excessive or significantly increases, it may need further assessment, but it is not as immediate a concern as unexplained bleeding. Thus, any instance of unexplained bleeding should always lead to prompt medical evaluation.
