During a prenatal visit for a client diagnosed with placenta previa, why is a vaginal examination avoided?

A vaginal examination is avoided in a client diagnosed with placenta previa primarily to avoid initiating severe hemorrhage. Placenta previa occurs when the placenta is located near or covering the cervical opening, and any manipulation in this area can disrupt the delicate vascular connections, potentially leading to significant bleeding.

Performing a vaginal exam could cause the placenta to tear or incur trauma, which can be life-threatening for both the mother and the fetus. Therefore, the priority in managing a client with placenta previa is to minimize risk factors that could lead to hemorrhage, making it crucial to avoid procedures that could exacerbate the situation.

While preventing complications of labor is relevant, the direct link to hemorrhagic risk is the primary concern. Monitoring fetal positioning is also important, but it does not outweigh the threats posed by the potential for severe hemorrhage. Finally, while maternal anxiety is a factor in maternity care, it does not serve as the primary reason for avoiding vaginal examinations in the context of placenta previa.
