36 Questions
What is the mean error of digital examination when cervical dilation is >8 cm?
0.75 ± 0.73 cm
What defines the latent phase during labor?
Gradual cervical change
Which tool allows graphic comparison of cervical dilation progress over time with expected progress?
Partogram
In nulliparous patients, where does the inflection point in labor often occur?
At approximately 6 cm or more dilation
What does right deviation from the expected labor progress curve on a partogram suggest?
Protraction or arrest disorder
Which phase of labor is characterized by more rapid cervical change?
Active phase
What has not been proven to significantly improve obstetric outcome according to the text?
Routine use of a partogram
What is the effect of right deviation from the expected labor progress curve on a partogram?
Protraction or arrest disorder
How is the onset of labor typically identified?
Regular contractions every 3-5 minutes for more than an hour
Why is a nondigital method for examining cervical dilation not available for clinical use?
Technological limitations
Why is it impossible to determine precise times of labor onset and complete dilation?
Cervical changes are subtle at the beginning
When does the second stage of labor begin?
At complete dilation
When are cervical examinations usually performed during labor?
At regular intervals in the first and second stages
What is a limitation of digital examination during labor?
It is imprecise for determining labor progress
In induced labors, how do the active phase and second stage durations compare to spontaneous labors?
Similar in both types of labors
When is a cervical examination performed to evaluate fetal descent during labor?
At one- to two-hour intervals in the second stage
Why are more frequent cervical examinations discouraged during labor?
They raise the risk of contaminating intrauterine contents with vaginal flora
What triggers a cervical examination to determine full dilation of the cervix?
The parturient feeling the urge to push
Nulliparous patients generally have faster labors than parous patients.
False
Abnormal labor, dystocia, and failure to progress are precise terms used to describe deviations in labor patterns.
False
Cervical dilation becomes faster after the cervix is completely closed.
False
The second stage of labor involves descent and eventual expulsion of the fetus.
True
Determining whether labor is progressing normally is not a key component of intrapartum care.
False
Measuring the progress of labor is an exact science according to the text.
False
The Friedman curve was based on the evaluation of 500 nulliparous and 500 parous patients in the mid-1950s.
True
The latent phase of labor is characterized by slow cervical dilation until 3 to 4 cm.
True
The active phase of labor begins when the cervix reaches 9 cm of dilation.
False
The deceleration phase in cervical dilation occurs around 9 cm of dilation.
True
The rate of cervical dilation during the active phase is slower for nulliparous patients compared to parous patients.
False
The norms established by the Friedman curve have never been widely accepted as the standard for assessment of normal labor progression.
False
In induced labors, the active phase and second stage durations are generally longer than in spontaneous labors.
False
Cervical examinations are performed every two to four hours during the first stage of labor.
True
More frequent cervical examinations increase the risk of contaminating the intrauterine contents with vaginal flora.
True
Digital examination can precisely determine whether cervical dilation and fetal descent are advancing slowly or not at all.
False
Cervical examinations are performed when the parturient feels the urge to push.
False
During labor, more frequent examinations are discouraged to avoid contaminating the intrauterine contents with analgesia.
False
Learn about the assessment of labor progress in induced and spontaneous labors, including the durations of the active phase and second stage. Understand the importance of digital examinations to document cervical dilation, effacement, and fetal station.
