Test Bank Questions and Answers for ACOG Practice Bulletin, Induction of Labor 100% Pass
What is the goal of cervical ripening? - Answers It is to facilitate the process of cervical softening,
thinning, and dilating with the resultant reduction in the rate of failed induction and induction to
delivery time.
Review: What is the generally regarded cutoff for a cervix that is unfavorable for induction? - Answers
This is when the bishop score is 6 or less.
Review: What are the different methods for cervical ripening? - Answers -Mechanical cervical dilators
(including hygroscopic dilators, osmotic dilators, Foleys, extraamniotic saline infusions)
-Synthetic PGE1 or PGE2
Review: What are the PGE1 and PGE2 analogs and how are they administered? - Answers -PGE1:
Misoprostol. Administered intravaginally, orally, sublingually, and rectally.
-PGE2: Dinoprostone. Gel and vaginal insert.
Review: What are the different methods for induction of labor (*after cervix is ripe*)? - Answers -
Oxytocin
-Membrane stripping
-Amniotomy
-Nipple stimulation
What are predictors of a successful response to oxytocin for induction? - Answers -Lower BMI
-Greater cervical dilation, parity or gestational age
Partial review: How does membrane stripping function to induce labor? - Answers Stripping or sweeping
the amniotic membranes increases PLA2 activity and PGF2alpha levels.
-This increases the rate of induction w/in 48 hours
Mostly review: When is amniotomy most appropriate for inducing labor? What is done concurrently? -
Answers If the cervix is favorable. Better results when combined with oxytocin than amniotomy alone
Review: How effective is nipple stimulation for inducing labor? Other benefits? - Answers *Unilateral*
breast stimulation is effective in inducing labor in patients with favorable cervices and (in this one study)
doesn't raise the risk of uterine tachysystole, while lowering the risk of postpartum hemorrhages (in
low-risk patients).
How do you appropriately measure uterine contractions? - Answers Count the number of contractions
present in a ten minute window averaged over 30 minutes.
