what are the positive signs of preganancy?
diagnostic:
audible fetal heart tones via doppler, ultrasound @ 4-6 weeks and feeling baby move by examiner(20 weeks)
what is placenta previa?
when the placenta implants in the lower segment of the uterus near or over the cervical os;
abnormal implantation results in bleeding in the 3rd trimester as cervix begins to dilate and efface
what is important to remember with previa?
NO cervical exams

betamethosone use
it can help speed up lung development in preterm babies. Betamethasone causes the release of surfactant, a substance that lubricates the lungs so that they do not stick together when the infant breathes.

HELLP syndrome stands for
hypertension in pregnancy as well as Hemolysis, Elevated Liver enzymes, Low Platelet
antidote for magnesium sulfate?
