Stages of Labor
100

The "P" that involves contractions of the myometrium and causes for cervical dilation and effacement

What is Powers?

100

This contraction description is calculated from the beginning of one contraction to the beginning of the next contraction

What is the contraction frequency?

100

This is the normal baseline of the fetal heart rate

What is 110-160bpm?

100

This is usually the largest part of the fetus

What is fetal skull?

100

This the phase of the first stage of labor in which the woman turns attention inward, she is dilated to 5-7cm, contractions are 2-5 minutes apart, and lasting 45-60 seconds

What is the active phase of the first stage of labor?

200

The "P" that involves maternal postures and physical positions

What is Position?

200

This contraction description is calculated from the beginning of the contraction to the end of the same contraction

What is the contraction duration?

200
This is the term for a sustained fetal heart rate greater than 160bpm

What is fetal tachycardia?

200

This is determined by the part of the fetus that enters the pelvis first

What is fetal presentation?

200

This is the stage of labor in which the woman dilates to 10cm, and the cervix completely effaces 

What is the first stage of labor?

300

The "P" that involves the fetus, including fetal position and presentation

What is Passenger?

300

This is description of the contraction is evaluated by palpating the woman's abdomen during contractions

What is the contraction intensity?

300

This is the cause of the type of fetal decelerations that decrease at the beginning of the contraction, get to the lowest point at the peak of the contraction, and return to baseline by the end of the contraction

What is fetal head compression?

300

This refers to the relationship between the fetal spine and the maternal spine

What is fetal lie?

300

This is the stage of labor that includes the first 1-4 hours after delivery

What is the fourth stage of labor?

400

The "P" that involves the pelvis and birth canal

What is Passage?

400

This is phase of the contraction in which the contraction is at its peak intensity

What is the acme phase of the contraction? 

400

This is the cause of the type of fetal decelerations that decrease rapidly, get to the lowest point for a while, and return to baseline rapidly

What is fetal cord compression?

400

This is the relationship of the fetal parts to one another, noted by the flexion or extension of the fetal joints

What is fetal attitude?

400

This is the stage of labor that includes the time from delivery of the baby to the delivery of the placenta

What is the third stage of labor?

500

The "P" that involves the psychosoial aspect that results in the woman's wellness and satisfaction

What is Psyche?

500

This is phase of the contraction in which the contraction begins in the fundal area and spreads throughout the uterus

What is the increment phase of the contraction

?

500

This is the cause of the type of fetal decelerations that decrease at, of after, the peak of the contraction, reach the lowest point, and then return to baseline after the end of the contraction

What is utero-placental insufficiency?

500

This refers to the relationship of the fetus in relationship to the maternal pelvis

What is fetal position?

500

This is the stage of labor that includes the time from 10cm dilation to delivery of the baby

What is the second stage of labor?
