A client suspected of having abruptio placentae should be assessed for which of the following signs?

In the case of abruptio placentae, it is critical to assess for bleeding, which can either be concealed or apparent. Abruptio placentae involves the premature detachment of the placenta from the uterine wall, leading to potential complications that can manifest in unexpected bleeding patterns. Concealed bleeding occurs when blood collects behind the placenta, which may not be evident externally. In contrast, apparent bleeding is visible and occurs when blood flows out of the vagina. The nature of the bleeding is essential in identifying the severity of the condition and determining the appropriate course of action.

While abdominal rigidity, a painful abdomen, and changes in the size of the placenta are relevant concerns in the context of placental issues, they do not specifically encapsulate the critical nature of assessing the type of bleeding associated with abruptio placentae. The identification of the bleeding type is paramount, as it directly influences the urgency and management of the situation, making it the most significant sign to evaluate in this scenario.
