What symptom is most commonly associated with placental abruption?

• A. Increased fetal movement
• B. Severe rigidity
• C. Quickening
• D. Amniotic fluid leakage

Answer: (B)

The most commonly associated symptom with placental abruption is severe rigidity of the abdomen. This occurs because when the placenta detaches from the uterine wall, it often leads to significant internal bleeding and irritation of the uterine muscles. The contraction of these muscles can create a sense of firmness or rigidity in the abdomen, which is a key indicator of this serious condition.

In the context of placental abruption, other symptoms such as severe abdominal pain, vaginal bleeding, and fetal distress may also be present. However, the rigidity is particularly noted as it indicates a major alteration in the uterine environment, which is critical for monitoring in cases of suspected abruption.
