Following chorionic villus sampling, which finding requires immediate intervention?

• A. Uterine cramping.
• B. Abdominal tenderness.
• C. Systolic blood pressure < 100 mmHg.
• D. Intermittent nausea.

Answer: (A)

In this post-procedure context, new or worsening uterine cramping is the signal that immediate assessment is needed because it directly points to uterine irritability or impending pregnancy complication after a chorionic villus sampling. The uterus contracting more than expected or in a way that suggests distress can threaten the viability of the pregnancy, so prompt evaluation is essential to check fetal status, bleeding, and maternal condition and to initiate any necessary management right away. Mild abdominal tenderness or intermittent nausea are common or nonspecific after the procedure and do not, on their own, indicate an urgent obstetric complication. While significant hypotension would also require urgent care, the symptom most indicative of an immediate need for intervention in this scenario is persistent uterine cramping.
