88
Q

BP gt 160/110 in pregnancy, no HTN at baseline, diagnosis?

A

gestational HTN vs preeclampsia - look for proteinuria

89
Q

Name 7 alarm sxs that earn you preeclampsia with severe features

A

90
Q

Why might you get RUQ abd pain and increased LFTs with preeclampsia?

A

There is a stretch of glisson’s capsule leading to decreased blood flow to the liver, leading to increased LFTs; pain is due to inflammation and stretching of the capsule around the liver

91
Q

HA, vision change, HTN in pregnancy, diagnosis and next step?

A

cesarean delivery

102
Q

Name 5 initial measures to tx fetal hypo perfusion (late decels)

A

1) change in maternal position to left lateral position (which increases perfusion to uterus); 2) maternal supplemental oxygenation; 3) tx of maternal hypotension; 4) discontinuation of oxytocin; 5) intrauterine resuscitation w/tocolytics and IV fluids
