38 yo F at 34 wks gestation hasn't felt fetal movement for the last 18 hrs. Complicated by fetal growth restriction at 28 wks when u/s showed estimated fetal weight at 3rd percentile. Since then, pt was followed w/serial biophysical profiles & umbillical artery doppler sonography which were normal. VSS. Cervix closed&posterior. Fetal heart tones NOT heard on doppler. bedside u/s shows no fetal cardiac activity. blood type is A rh negative, kleihauer betke test negative. She's informed about intrauterine fetal demise. Asks if any risks associated w/waiting for labor onset? appropriate response?
a) Increased risk of infection
b) Increased risk of postpartum hemorrhage
c) Increased risk of uterine rupture
d) Increased risk of disseminated intravascular coagulation
