Answer 11

fetal anoxia

Question 12

precipitate dilation

Answer 12

5+ cm/hour in nullipara and 10cm/hour in multipara

Question 13

risks of precipitate birth

maternal hemorrhage, tearing, fetal subdural hematoma, fetal RDS

Question 14

medications to encourage effacement

Answer 14

Question 15

how does the foley bulb work?

Answer 15

oxytocin loop, strengthens contractions to increase dilation

large baby - macrosomia, post term

Question 22

nursing interventions for shoulder dystocia

Answer 22

McRobert’s Maneuver, suprapubic pressure

Question 23

CPD

Answer 23

cephalopelvic disproportion, fetal head is too large to pass

Question 24

CPD treatment

Answer 24

can have a TOL, if adequate progress does not occur then C section

Question 25

Answer 25

procedure to turn fetus to occipital/cephalic presentation

Question 26

risks of external cephalic version

Answer 26

rupture, cord compression

Question 27

Answer 27

umbilical cord attaches outside of the placenta, vessels are exposed

Question 28

velamentous cord insertion concerns

Answer 28

hemorrhage

Question 29

vasa previa

Answer 29

umbilical cord delivers before the fetus, risk of cord tearing
