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
|
