Which is the best predictor of successful vaginal birth?
Descent of the presenting part during labor
A 30 year old primigravid patient at term progresses from 4cm dilation to 7 cm in 5 hours. How would this labor be described?
A protraction disorder
A 22 year old multiparous patient has been pushing for 2 hours resulting in no descent of the presenting part. This would be classified as
An arrest disorder
Which of the following maternal factors can prevent accurate clinical assessment of uterine contractions?
For a patient in active labor, which of the following provides a quantitative measurement of the strength of her uterine contractions
Intrauterine pressure catheter
Which of the following presentations typically converts to either a vertex or brow presentation?
Normal fetal heart rate variability is characterized by an amplitude range that is
Marked fetal heart rate variability is characterized by an amplitude range that is
> 25 bpm
Which of the following presentations usually resolves spontaneously as labor continues?
A 22 year old G1P0 patient presents at term with complaints of contractions for many hours. Her cervix is 100% effaced and is dilated to 3 cm. In a nulliparous patient, the latent phase of labor is defined as prolonged if it lasts longer than
A 37 year old G4P3 patient reports having contractions “all day”. In Multiparous paitients, the latent phase is defined as prolonged if it lasts more than
A 30 year old G2P1 at term is in adequate active labor with cervical dilation unchanged at 6cm as documented by several examiners. There has been secondary arrest of dilation when cervical dilation during the active phase of labor stops for at least
Which of the following is the appropriate management of a prolonged latent phase?
Which of the following is a selection criterion that would allow for the external cephalic version?
Normal fetus with reassuring fetal heart tracing
Outlet forceps-assisted vaginal delivery is appropriately considered with fetal head at what station?
at the pelvic floor
Low forceps assisted vaginal delivery occurs with the fetal head at what station?
At the 2+ station
A patient has been in the second stage of labor for 2.5 hours. Fetal heart tones are reassuring and there is no clinical evidence of cephalopelvic disproportion. The next step in management of this patient should be
Oxytocin administration if uterine contractions are inadequate
Vibroacoustic stimulation is used to elicit what type of fetal heart rate response?
Amnioinfusion to relieve umbilical cord compression is useful in cases of
Variable fetal heart rate deceleration
If a fetus experiences progressive and sustained hypoxia, the mixed metabolic and respiratory acidosis that may ensue typically results from
In high risk patients, intermittent fetal heart rate auscultation to monitor fetal well being should be employed at least how often during the active phase of labor?
Every 15 minutes
In high risk patients, intermittent fetal heart rate auscultation to monitor fetal well being should be employed at least how often during the second stage of labor?
Every 5 minutes
Baseline fetal tachycardia is defined as a heart rate greater than how many beats per minute?
The most common cause of fetal tachycardia
Baseline fetal bradycardia is defined as a heart rate less than how many beats per minute?
A fetal heart rate below how many beats per minute is an ominous sign that may presage fetal death?
Fetal heart accelerations associated with
Reassuring fetal status
Early fetal heart rate decelerations are associated with
Pressure on the fetal head
Variable fetal heart rate decelerations are associated with
Umbilical cord compression
