Choice A rationale:

Uterine rupture.

Rationale: Uterine rupture is not a common complication of ectopic pregnancy.

Ectopic pregnancies occur outside the uterus, typically in the fallopian tube.

Therefore, uterine rupture is not a direct risk associated with ectopic pregnancy.

Choice B rationale:

Ovarian cyst.

Rationale: Ovarian cysts are not a direct complication of ectopic pregnancy.

Ectopic pregnancy involves the implantation of the fertilized egg outside the uterus, often in the fallopian tube, but it does not directly affect the ovaries in the same way as ovarian cysts.

Choice C rationale:

Tubal rupture.

Rationale: Tubal rupture is a severe and life-threatening complication of ectopic pregnancy.

As the embryo grows in the fallopian tube, it can cause the tube to rupture, leading to severe internal bleeding.

This is a critical emergency that requires immediate medical intervention to prevent shock and further complications.

Choice D rationale:

Endometriosis.

Rationale: Endometriosis is a separate medical condition characterized by the presence of endometrial tissue outside the uterus.

While endometriosis can be associated with pelvic pain and infertility, it is not a direct complication of ectopic pregnancy.
