Which signs best indicate hemorrhagic shock in obstetric emergencies?

• A. Rapid heart rate, falling blood pressure, and decreased urine output.
• B. Normal vital signs.
• C. Elevated blood pressure with tachypnea.
• D. No symptoms.

Answer: (A)

Hemorrhagic shock from obstetric bleeding shows up as signs of reduced blood volume and poor perfusion. The body tries to compensate by increasing heart rate to maintain cardiac output, so rapid heart rate is an early clue. As blood loss continues and volume remains low, blood pressure falls because there is less blood returning to the heart to pump out. The kidneys receive less blood, so urine production drops, leading to decreased urine output. When these three together— fast pulse, dropping blood pressure, and reduced urine output—occur in an obstetric emergency, they strongly indicate hypovolemia from hemorrhage and the need for urgent intervention.

Normal vital signs, elevated blood pressure with tachypnea, or no symptoms do not align with the typical progression of hemorrhagic shock in this setting.
