Which is an early warning sign of maternal decompensation in uterine rupture?

• A. Tachycardia
• B. Severe bradycardia
• C. Hypotension requiring vasopressors
• D. Pulmonary edema

Answer: (A)

In uterine rupture, the first cue that maternal blood loss is causing trouble is an increasing heart rate. The body compensates for hemorrhage by mobilizing sympathetic responses to maintain blood flow, so the pulse climbs before blood pressure falls. This makes tachycardia the earliest warning that the mother is decompensating due to bleeding. As bleeding continues, blood pressure can drop and shock develops, which is when you’d see hypotension requiring vasopressors. Severe bradycardia is a much later, ominous sign that can indicate impending cardiac arrest or other severe insults, not an early warning. Pulmonary edema likewise reflects established overload or failure after hemodynamic collapse, not an initial warning. So the initial, paling-early sign to watch for is a rising heart rate.
