Question 1

A multiparous patient at 6 cm dilation has contractions every 2 minutes, lasting 70 seconds, with strong intensity on palpation. Her labor has not progressed in 2 hours. What term BEST describes this situation?

Accepted Answer

Active phase arrest

Answer

Active phase arrest is defined as no cervical change for 4 hours with adequate contractions or 6 hours with inadequate contractions in the active phase.

Question 2

The nurse is monitoring a patient receiving oxytocin augmentation. Which FHR pattern requires the nurse to STOP the infusion immediately?

Accepted Answer

Repetitive late decelerations with minimal variability

Answer

Repetitive late decelerations with minimal variability (Category III) indicate uteroplacental insufficiency, requiring immediate oxytocin discontinuation and further resuscitation measures.

Question 3

During the second stage of labor, the nurse notes the fetal head crowning between pushes. What technique should the nurse use to control birth and prevent perineal lacerations?

Accepted Answer

Apply gentle counterpressure to the fetal head and support the perineum

Answer

Gentle counterpressure on the crowning head (the Ritgen maneuver variant) and perineal support slows delivery and reduces severe laceration risk.

Question 4

A patient's amniotic fluid appears green and thick immediately after spontaneous rupture of membranes. The priority nursing concern is:

Accepted Answer

Meconium aspiration syndrome risk requiring preparation for neonatal resuscitation

Answer

Thick meconium-stained amniotic fluid indicates in-utero passage of meconium and places the neonate at risk for meconium aspiration syndrome, requiring a skilled neonatal team at delivery.

Question 5

Which maternal vital sign change during labor warrants IMMEDIATE provider notification regardless of other findings?

Accepted Answer

Blood pressure of 158/105 mmHg on two readings 15 minutes apart

Answer

A blood pressure of 158/105 mmHg or higher on two readings 15 minutes apart meets the diagnostic threshold for severe-range hypertension requiring urgent antihypertensive treatment.
