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?


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.


Abnormal labor, dystocia, and failure to progress are precise terms used to describe deviations in labor patterns.


Cervical dilation becomes faster after the cervix is completely closed.


The second stage of labor involves descent and eventual expulsion of the fetus.


Determining whether labor is progressing normally is not a key component of intrapartum care.


Measuring the progress of labor is an exact science according to the text.


The Friedman curve was based on the evaluation of 500 nulliparous and 500 parous patients in the mid-1950s.


The latent phase of labor is characterized by slow cervical dilation until 3 to 4 cm.


The active phase of labor begins when the cervix reaches 9 cm of dilation.


The deceleration phase in cervical dilation occurs around 9 cm of dilation.


The rate of cervical dilation during the active phase is slower for nulliparous patients compared to parous patients.


The norms established by the Friedman curve have never been widely accepted as the standard for assessment of normal labor progression.


In induced labors, the active phase and second stage durations are generally longer than in spontaneous labors.


Cervical examinations are performed every two to four hours during the first stage of labor.


More frequent cervical examinations increase the risk of contaminating the intrauterine contents with vaginal flora.


Digital examination can precisely determine whether cervical dilation and fetal descent are advancing slowly or not at all.


Cervical examinations are performed when the parturient feels the urge to push.


During labor, more frequent examinations are discouraged to avoid contaminating the intrauterine contents with analgesia.


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.
