1. A gravida 2 para 1 woman at 39 weeks presents in active labor.
Which cervical findings indicate active labor?
A. 2 cm dilation, 50% effacement
B. 3 cm dilation, 60% effacement
C. 6 cm dilation, 90% effacement
D. 1 cm dilation, 100% effacement
Answer: C
Active labor is generally defined as cervical dilation of 6 cm or greater
with progressive change.
2. Which fetal heart rate (FHR) baseline is considered normal?
A. 100–110 bpm
B. 110–160 bpm
C. 160–180 bpm
D. 90–100 bpm
Answer: B
A normal baseline FHR ranges from 110 to 160 beats per minute.
3. Early decelerations are most commonly associated with:
A. Umbilical cord compression
B. Uteroplacental insufficiency
C. Fetal head compression
D. Maternal hypotension
,Answer: C
Early decelerations mirror contractions and result from vagal
stimulation due to head compression.
4. A late deceleration is characterized by:
A. Abrupt onset and recovery
B. Occurring before the contraction peak
C. Delayed onset after the contraction peak
D. Variable timing
Answer: C
Late decelerations begin after the peak of the contraction and
indicate uteroplacental insufficiency.
5. Which intervention is priority for recurrent late decelerations?
A. Vaginal exam
B. Reposition the mother to her side
C. Increase oxytocin
D. Administer narcotics
Answer: B
Maternal repositioning improves uteroplacental perfusion and is a
first-line intervention.
6. Which medication is used for tocolysis?
A. Oxytocin
B. Methylergonovine
C. Nifedipine
D. Misoprostol
,Answer: C
Nifedipine is a calcium channel blocker commonly used to suppress
preterm labor.
7. The most reliable indicator of uterine tachysystole is:
A. Duration of contractions
B. Strength of contractions
C. More than 5 contractions in 10 minutes
D. Cervical dilation
Answer: C
Uterine tachysystole is defined as more than five contractions in 10
minutes averaged over 30 minutes.
8. Which finding suggests chorioamnionitis?
A. Maternal bradycardia
B. Maternal fever and uterine tenderness
C. Clear amniotic fluid
D. Decreased WBC count
Answer: B
Chorioamnionitis presents with maternal fever, uterine tenderness,
and often fetal tachycardia.
9. A newborn delivered at 36 weeks is classified as:
A. Term
B. Postterm
C. Late preterm
D. Very preterm
, Answer: C
Late preterm infants are born between 34 and 36 6/7 weeks
gestation.
10. Which sign indicates placental abruption?
A. Painless vaginal bleeding
B. Uterine rigidity and abdominal pain
C. Hypotension without bleeding
D. Absence of contractions
Answer: B
Placental abruption often presents with painful bleeding and a firm,
rigid uterus.
11. The purpose of Leopold maneuvers is to determine:
A. Cervical effacement
B. Fetal lung maturity
C. Fetal position and presentation
D. Placental location
Answer: C
Leopold maneuvers assess fetal lie, presentation, and position.
12. Which assessment best confirms rupture of membranes?
A. Ultrasound
B. Nitrazine test alone
C. Pooling of fluid in the vaginal vault
D. Maternal report of leaking
