100

This is the normal fetal heart rate baseline.

110-160 BPM.

100

This is the stage of labor in which complete dilation occurs. 

The first stage of labor.

100

This is the first maneuver used for shoulder dystocia. 

McRoberts maneuver.

100

This medication is commonly used to induce or augment labor. 

Pitocin (Oxytocin).

100

G2P1.

Second pregnancy, one delivery at a viable gestation.

200

These decelerations are usually caused by cord compression.

Variable decelerations.

200

The fetal head is at this station when it is level to the ischial spine. 

0 station.

200

This is the most common cause of postpartum hemorrhage.

Uterine atony.

200

This uterotonic should be avoided in patients with hypertension.

Methergine. 

200

SROM.

Spontaneous rupture of membranes. 

300

This category of fetal heart rate tracing has absent variability with recurrent late decelerations

Category III

300

This defines the second stage of labor.

Pushing.
300

This is the amount of blood loss that quantifies a postpartum hemorrhage in a cesarean delivery.

1000 ml

300

This uterotonic should be avoided in patients with asthma.

Hemabate.
300

VBAC.

Vaginal birth after cesarean.

400
Moderate variability is indicative of this. 

An adequately oxygenated fetus.

400

This is when the fetal head becomes visible at the vaginal opening.

Crowning. 

400

This is the antidote for magnesium sulfate.

Calcium gluconate.

400

This medication is used for seizure prophylaxis in patients with severe preeclampsia.

Magnesium sulfate.

400

GBS.

Group B Streptococcus.

500

This is the area of maximum intensity of the fetal heart rate.

Fetal back. 

500

These are the five "P's" of labor.

Determining factors of how childhood progresses:

  • Passenger: Refers to the fetus. The baby's size, lie, presentation (e.g., cephalic/head-first vs. breech)
  • Passageway: Refers to the maternal pelvis and soft birth canal. The size and shape of the pelvis 
  • Powers: Represents the physical forces driving the baby down.
  • Position: Highlights the mother's laboring posture.
  • Psyche: Represents the psychological and emotional state of the birthing person. 
500

These are three factors that increase likelihood of postpartum hemorrhage.

  • Prolonged labor
  • Oxytocin induction/augmentation
  • Multiple gestation
  • Polyhydramnios
  • Macrosomia
  • Chorioamnionitis
  • Grand multiparity
500

These are two signs of magnesium toxicity. 

  • Respiratory depression
  • Absent deep tendon reflexes
  • Decreased urine output
  • Altered level of consciousness
500

PPROM.

Preterm premature rupture of membranes.
