Which of the following statements about prolapse of the umbilical cord is INCORRECT?
Incorrect - Manual replacement of the cord is indicated when the presenting part is not engaged in the pelvis (Correct - it occurs in approx 0.5% patients, it occurs more frequently in patients of high parity, it most frequently occurs in breech presentation, with twins, and in the presence of polyhydramnios, and it is associated with an increased perinatal mortality)
Which of the following is NOT associated with uterine rupture?
Amniocentesis
(uterine ruputure is associated with previous c-section, myomectomy, administration of oxytocin, and difficult forceps delivery)
Older gravidas have an increased incidence of
all of the above (uterine inertia, malpresentation, and hypertension)
The breech hydrocephalus is best managed by
cesarean delivery
Abnormal labor, or dystocia, can result from
all of the above (anatomic anomalies of the fetus, anatomic anomalies of the maternal body pelvis, anatomic anomalies of the uterus, and functional abnormalities of the uterus)
No progress from the latent to the active stage of labor in a nullipara is defined as prolonged latent phase if it lasts more than how many hours?
> 20 hours
Protraction disorder is an abnormal labor pattern related to
prolonged active phase of labor
Arrest disorder is an abnormal labor pattern related to
secondary arrest of dilatation
Cervical dilation that proceeds at less than 1.2 cm/hr (for a nulligravida) would be classified as
a protraction disorder
A situation where there has been no descent of the presenting part for over 1 hour during the second stage of labor would be classified as
an arrest disorder
Which of the following provides a quantitative measurement of the strength of uterine contractions?
Intrauterine pressure catheter
For a labor pattern to be considered optimal, contractions must generate a maximum intrauterine pressure of approximately how many mm Hg?
50 to 60 mm Hg
The incidence of shoulder dystocia and the need for cesarean delivery increase markedly if the fetus has an estimated weight of at least
4,500 g
Which of the following typically converts to either a vertex or face presentation?
Brow
What is the frequency of brow presentation?
1 in 3,000
What is the frequency of face presentation?
1 in 600
Which of the following usually resolves spontaneously as labor continues?
Compound presentation
Causes of dystocia may include
all of the above (a contracted bony maternal pelvis, a distended bladder or colon, an adnexal mass, and a uterine leiomyomata)
Which of the following is appropirate to use for the augmentation of labor?
Oxytocin
In a primigravid patient, the active phase of labor is defined as prolonged if it lasts longer than
12 hours
In multiparous patients, the active phase is defined as prolonged if it lasts
6 hours
There has been secondary arrest of dilation when cervical dilation during the active phase of labor stops for as least
2 hours
What is the Bishop's score for the following findings: a dilation of 1 to 2 cm, 60% effacement, a cephalic part of -1 station, and a soft cervix that is midposition?
7
There is a significant likelihood that induction has failed if the Bishop's score falls below
4 points
The prolonged latent phase in labor may be managed by
all of the above (rest, augmentation with pitocin, and amniotomy)
Which of the following is NOT a risk to the fetus from prolonged labor?
Hemorrhage is NOT a risk to fetus from prolonged labor
(prolonged labor - increased risk of sepsis, subdural hematoma, and delivery associated trauma)
Meconium aspiration syndrome is associated with
All of the above (prolonged labor, postdates pregnancy, intrauterine growth restriction, and chronic maternal hypertension)
What percent of singleton term deliveries are breech presentations?
3%
Vaginal delivery of the term breech is generally avoided when the fetus weighs less than
2,000 g
Which of the following is NOT a selection criterion for external cephalic version?
Presenting part in the pelvis is NOT a criterion for ECV
(criterion for external cephalic version are: normal fetus, reassuring fetal heart rate tracing, no uterine surgical scars, and adequate amniotic fluid)
All of the following are risks of external cephalic version EXCEPT
Sepsis is not a risk of ECV
(risks of ECV include: uterine rupture, cord accident, placental abruption, and premature rupture of the membranes)
Cesarean delivery is required in what percent of term breeches because of hyperextension of the fetal head?
5%
Outlet forceps-assisted vaginal delivery is appropriately considered with the fetus at what station?
At the perineal floor
Low forceps-assisted vaginal delivery occurs with the fetus at what station?
At the +2 station
Midforceps-assisted vaginal delivery is defined with the fetus at what station?
Above the +2 station
Uterine contractions occurring at irregular intervals is characteristic of
false labor
Sedation provides relief from discomfort of uterine contractions in
false labor
Uterine contractions of unchanging intensity are characteristic of
false labor
Abdominal but not back discomfort with contractions is characteristic of
false labor
Vasa previa is a
contraindication to induction of labor
Prior classic uterine incision is a(n)
contraindication to induction of labor
Premature rupture of membranes at term is a(n)
indication for induction of labor
Intrauterine fetal demise is a(n)
indication for induction of labor
Cord presentation is a(n)
contraindication to induction of labor
Abnormal fetal lie is a(n)
contraindication for induction of labor
Chorioamniotitis is a(n)
indication for induction of labor
Active genital herpes infection is a(n)
contraindication to induction of labor
The delivery of the fetal head in the assisted breech delivery is often facilitated with what type of forceps?
Kielland
