OB FINAL QUESTIONS WITH
ACCURATE ANSWERS
5 P's affecting labor correct answer Passenger, Passageway, Powers, Position of
mother, Psychological response
active phase of labor correct answer 4 to 7 cm of dilation
amniotomy correct answer artificial rupture of membranes
antenatal glucocorticoids correct answer medications given to pregnant women
expecting preterm delivery; promote fetal lung maturity; administered between
24-34 weeks; ex) betamethasone 12 mg IM x2 (24hrs apart) & dexamethasone 6
mg IM x4 (12hrs apart)
augmentation of labor correct answer stimulation of uterine contractions after
labor has started but progress is unsatisfactory; implemented for mgmt of
hypotonic uterine contractions; common methods: oxytocin infusion, amniotomy
babinski reflex correct answer reflex in which an infant fans out its toes in
response to a stroke on the outside of its foot
bishop score correct answer cervix score; pre-labor scoring system that predicts
the readiness of cervix & whether induction will be necessary; score of 8 or
greater means chances of vaginal delivery are good, score of 6 or less means
cervix is not ready
, category II FHR correct answer FHR pattern that indicates fetus is in
compensatory mode; either mod variability w/ recurrent late decels or variable
decels, minimal variability w/ recurrent variable decels, absent variability w/o
decels, bradycardia w/ mod variability, prolonged decels, or tachycardia; requires
evaluation & continued surveillance
category III FHR correct answer FHR pattern that indicates abnormal fetal acid-
base status; either absent variability w/ recurrent late decels, variable decels, or
bradycardia OR sinusoidal pattern; requires prompt eval & intervention
causes of PPH correct answer uterine atony, lacerations of genital tract,
hematomas, retained placenta, inversion of uterus, subinvolution
cephalohematoma correct answer a collection of blood under the scalp of a
newborn that does not cross suture lines & normally resolves on its own
cervical ripening methods correct answer methods used for softening the cervix
to progress labor: chemical agents (prostaglandins), mechanical & physical
methods (laminaria, balloon cath, membrane stripping), amniotomy
chorioamnionitis correct answer bacterial infection of the amniotic cavity;
ascending infection; major cause of complications; s/sx: maternal fever, fetal
tachycardia, uterine tenderness, foul odorous amniotic fluid; TX: IV abx
(ampicillin, pcn, gentamycin)
dysfunctional labor correct answer labor that does not result in normal progress
of cervical effacement, dilation, & fetal descent; can be d/t abnormal uterine
activity (hypertonic/hypotonic) or abnormal labor patterns (prolonged latent
