if tube ruptures, assess for hemorrhage
Placenta previa • patho • s/sx • dx • treatment • notes
- placenta has implanted abnormally in lower uterus and covers all or part of the cervix → prematurely separate when cervix begins to dilate and efface → baby doesn’t get O2 —placenta may deliver first; most common cause of bleeding in later months (7 mos)
- painless (spot/profuse) bleeding in 2nd half of pregnancy
- ultrasound
- bedrest if no active bleeding;
- -complete previa - hospitalization to prevent blood loss and fetal hypoxia if client goes into labor and fetal monitoring;
- -if there’s not much bleeding - bedrest and watch closely
- -monitor blood count, FHTs, contractions (call PHP)
- -C-section
- -NO VAGINAL EXAM

- -place client in Trendelenburg or knee-chest position
- -administer O2
- -monitor FHTs, Check FHTs when membranes rupture
- -cord compression = variable decels = C-section ASAP!
• if cord ceases to pulsate = fetal death
- -if still pulsating = fetus is being oxygenated to some degree
- -DO NOT push cord in
Shoulder dystocia • patho • s/sx • dx • treatment • notes
• fetal head is out but anterior fetal shoulder is stuck w/ maternal pelvis
–risk factors: LGA or >4000 grams macrosomic infants; gestational diabetes; hx of it; postdate delivery = large fetus
- delay in birth of shoulders once head is delivered
- “Turtle Sign” - fetal head after it’s delivered retracts back against the perineum
• McRoberts maneuver (hyperextend legs) or Mazzanti technique (suprapubic pressure)
–NEVER apply fundal pressure, only HCP
• risks to fetus - hypoxia, brachial plexus injury (Erb’s palsy), broken clavicle, Bell’s palsy
–maternal risks: traumatic delivery, bruised bladder, extension of episiotomy, rectal tear, torn cervix and/or uterus
Group B strep • patho • s/sx • dx • treatment • notes
- leading cause of neonatal morbidity
- no s/sx
- vaginal and rectal cultures 35-37 weeks and on admit to L and D
- prophylactic abx during L and D (IV Penicillin; Cephazoline or Clindamycin)
- risk factors: preterm <37 wks
- not an STI
- (+) prenatal cultures in current pregnancy
- premature rupture of membranes
- hx for early-onset neonatal GBS
- intrapartum maternal fever >100.4 F (38 C)
- -prev infant w/ GBS
