What manifestation should a nurse be aware of that indicates a potential complication in a client with a diagnosis of placenta previa?

In clients with a diagnosis of placenta previa, the most concerning manifestation is bright red vaginal bleeding without pain. This type of bleeding occurs due to the placental placement over or near the cervix, leading to potential complications, including hemorrhage. The characteristic of the bleeding being bright red and painless is a classic sign associated with this condition, and it necessitates immediate evaluation and possible intervention to ensure the safety of both the mother and the fetus.

High fever, severe abdominal pain, and increased fetal movement can indicate other complications or conditions. While high fever may suggest infection, it is not a typical sign of placenta previa. Severe abdominal pain could indicate issues such as placental abruption or other complications, but it is not a definitive sign of placenta previa. Increased fetal movement might be perceived as a positive sign of fetal well-being, but it does not directly relate to the complications associated with placenta previa. It is crucial for the nurse to be vigilant in monitoring for painless bright red vaginal bleeding as it can be an urgent indicator of the need for medical intervention in patients with this diagnosis.
