Ectopic Pregnancy: What is this?
Pregnancy where fertilized ovum implants outisde the uterine cavity. Includes fallopian tubes, cervix, and ovary
Ectopic Pregnancy: Why is this a problem?
Draws blood supply from site of abnormal implantation. As it enlarges, creates potential for organ rupture because only uterus can expand. Leads to hemorrhage, infertility or death
Ectopic Pregnancy: What does Misoprostol do?
stimulates uterine contractions to terminate a pregnancy.
Ectopic Pregnancy: What is Mifepristone?
Acts as progesterone antagonist, allowing prostaglandins to stimulate uterine contractions

Painless, bright-red vaginal bleeding occuring during 2nd or third trimester. Bleeding stops and goes.
Placenta Previa and Health Hx and Physical Exam: Why is bleeding thought to occur?
Due to the thining of the lower uterine segment in preparation for the onset for labor.
Placenta Previa and Health Hx and Physical Exam: What happens when bleeding occurs at implantation site in lower uterus?
Uterus cannot contract adequately and stop the flow of blood from the open vessels
Placenta Previa and Health Hx and Lab and Diag: How is placenta position determined?
Transvaginal ultrasound is done and MRI at delivery.
Placenta Previa and Monitoring Maternal-Fetal Status: What to do if woman if actively bleeding?

Abruptio Placentae: Perinatal consequences include wwhat
low birth weight, preterm delivery, asphyxia, stillbirth, and perinatal death
Abruptio Placentae Patho: What may cause this?
Degenerative changes in small maternal blood vessels resulting in blood clotting, degeenration of decidua (uterine lining) and possible rupture of vessel. Bleeding forms blood clot between placenta and uterine wall
