Final answer:
The correct treatment for a ruptured ectopic pregnancy is typically a c) laparotomy with salpingectomy to remove the ruptured fallopian tube and address the medical emergency.
Step-by-step explanation:
The treatment for a ruptured ectopic pregnancy is typically c) Laparotomy with salpingectomy.
This procedure involves removing the affected fallopian tube and is necessary when the ectopic pregnancy has caused a rupture, which is a medical emergency. Prompt surgical intervention is essential to prevent further bleeding and other complications. Methotrexate (MTX) is administered when an ectopic pregnancy is detected early and there is no rupture, as it can stop the growth of the embryo. Observation without intervention is not an appropriate treatment for a ruptured ectopic pregnancy, as it poses serious risks to the patient's health.
