Correct option is B
Before referral, stabilize the patient with IV fluids and administer uterotonics. This prevents hypovolemic shock during transfer. Surgical procedures are not feasible at PHC level.
Explanation of options: (a) ✘ Blood transfusion may not be available at PHC and causes delay in referral. (b) ✔ Correct; IV fluids + uterotonics stabilize circulation until definitive care. (c) ✘ Surgery is not possible at PHC; needs higher center. (d) ✘ Sending without stabilization increases mortality risk.
