Labor Progress & Mechanisms
Thinning of the cervix measured in percentages refers to this process.
What is effacement?
The peak strength of a contraction is called this.
What is the acme?
This medication class is used to slow or stop contractions when necessary.
What are tocolytics?
This bedside assessment technique helps determine fetal position using abdominal palpation.
What are Leopold maneuvers?
A loop of cord around the fetal neck is called this.
What is a nuchal cord?
When the fetal presenting part reaches the level of the ischial spines, labor is at this station.
What is zero station?
Time from start of one contraction to start of the next measures this contraction property.
What is frequency?
Magnesium sulfate is used in obstetrics primarily to prevent this complication.
What are seizures in preeclampsia?
This term describes the part of the fetus that is closest to the cervix during labor.
What is the presenting part?
Green-stained amniotic fluid suggests passage of this substance.
What is meconium?
A fetus in longitudinal lie with head down is in this type of presentation
What is cephalic presentation?
Contractions occurring every minute with little resting time between them indicate this condition.
What is uterine tachysystole?
When contractions become excessive during induction, the nurse anticipates decreasing or stopping this medication.
What is oxytocin?
A transverse fetal lie usually leads to this delivery method.
What is cesarean birth?
Heavy vaginal bleeding with abdominal pain during labor commonly indicates this placental complication
What is placental abruption?
This term describes how the fetus is oriented within the uterus, such as longitudinal or transverse.
What is fetal lie?
This external monitor measures contractions but does not measure their strength.
What is the tocodynamometer (TOCO)?
Maternal respiratory depression after opioid administration is treated with this medication.
What is naloxone?
When the widest diameter of the presenting part passes the pelvic inlet, this event has occurred.
What is engagement?
A sudden drop in fetal heart rate immediately after membrane rupture suggests this complication
What is cord prolapse?
Labor progress is partly measured by how far the cervix opens, known as this measurement.
What is cervical dilation?
Contractions lasting longer than 90 seconds may decrease this essential fetal supply.
What is oxygen?
Dinoprostone and misoprostol are given before induction mainly to achieve this cervical change.
What is cervical ripening?
A mismatch between fetal size and maternal pelvis that prevents vaginal birth is called this.
What is cephalopelvic disproportion?
After delivery of the fetal head, the shoulders fail to deliver because they are impacted behind this maternal pelvic structure.
What is the pubic symphysis?
