Welcome to your 👶 Preterm Labour, Normal & Abnormal Labour, and Operative Delivery Arena — 40 MCQs
1.
A 32-year-old primigravida at term reaches the second stage of labour. After prolonged pushing, fetal heart rate abnormalities develop. The cervix is completely dilated, the membranes are ruptured, and the fetal head is at a low station with its position clearly identified. The obstetrician considers an assisted vaginal birth. Which additional consideration is essential before proceeding?
2.
A 35-year-old woman with dichorionic twins presents in labour at 37 weeks. The first twin is cephalic, whereas the second twin is transverse. Both fetal heart rates are reassuring. The obstetrician explains that delivery planning must take account of the second twin's position and the team's expertise. Which complication is particularly important to anticipate after delivery of the first twin?
3.
A 30-year-old woman undergoes an emergency Caesarean section because of persistent fetal heart rate abnormalities. During postoperative counselling, the obstetric team explains that Caesarean delivery carries specific maternal risks. Which complication is particularly important to monitor during the immediate postoperative period?
4.
A 24-year-old primigravida at 35 weeks of gestation reports a sudden gush of clear fluid from the vagina. She has no painful uterine contractions. Sterile speculum examination demonstrates clear fluid leaking through the cervical opening. Which diagnosis is most likely?
5.
A 27-year-old woman at 30 weeks of pregnancy presents with painful contractions. Examination reveals cervical dilatation of 2 cm, but her contractions become less frequent after observation. The membranes remain intact, maternal observations are normal, and fetal assessment is reassuring. Which finding would most strongly support progression to established preterm labour?
6.
A 28-year-old woman undergoes vacuum-assisted vaginal delivery because of prolonged second-stage labour. The infant is delivered successfully, but examination reveals a scalp swelling related to the procedure. Which neonatal complication is particularly associated with vacuum extraction?
7.
A 26-year-old woman reaches full cervical dilatation during labour. Her fetal head is low, but she is exhausted and unable to complete delivery despite effective contractions. Fetal assessment is reassuring. The obstetrician considers vacuum-assisted vaginal delivery. Which condition is essential before attempting this procedure?
8.
A 24-year-old woman delivers a healthy term infant after an uncomplicated vaginal birth. The baby is immediately assessed for breathing, heart rate and general condition. What is the most appropriate initial principle of neonatal care following birth?
9.
A 30-year-old woman with a previous lower-segment Caesarean section presents at term in spontaneous labour. She wishes to attempt vaginal delivery. Which consideration is particularly important when assessing whether a trial of labour after Caesarean section is appropriate?
10.
A 24-year-old woman at 34 weeks presents with persistent watery vaginal discharge. A sterile speculum examination demonstrates pooling of clear fluid. She has no contractions, fever or uterine tenderness, and fetal assessment is reassuring. After confirming the diagnosis, which factor is most important in deciding between expectant management and delivery?
11.
A 25-year-old woman at 39 weeks of gestation is admitted in established labour. Her cervix is 6 cm dilated, the membranes are intact, and contractions are regular. Which event marks the completion of the first stage of labour?
12.
A 31-year-old woman in labour receives epidural analgesia. Shortly afterward, she develops dizziness and a significant fall in blood pressure. Which physiological effect most directly explains this complication?
13.
A 32-year-old multigravida in labour is being monitored using a partograph. The record includes cervical dilatation, fetal heart rate, uterine contractions and maternal observations. What is the principal clinical purpose of monitoring labour progress in this manner?
14.
A 28-year-old primigravida at term enters the second stage of labour. Examination reveals that the fetal buttocks are presenting instead of the head. Which term describes this fetal presentation?
15.
A 29-year-old woman undergoing a trial of labour after previous Caesarean section develops sudden severe abdominal pain followed by abnormal fetal heart rate findings and maternal tachycardia. The presenting fetal part appears to have moved higher in the pelvis. Which obstetric complication should be suspected immediately?
16.
A 29-year-old woman at 32 weeks of gestation presents with regular painful uterine contractions and lower backache. Examination reveals cervical dilatation of 3 cm with progressive cervical changes. The membranes are intact. Which diagnosis best describes this presentation?
17.
A 40-year-old woman at 41 weeks and 5 days of gestation is assessed for possible induction of labour. Ultrasound and fetal assessment are reassuring. What is an important reason for considering delivery planning in a pregnancy continuing beyond the expected date?
18.
A 29-year-old woman in active labour receives oxytocin for inadequate uterine contractions. After an increase in the infusion rate, contractions become excessively frequent, and fetal heart rate decelerations develop. Which physiological mechanism best explains the fetal heart rate abnormality?
19.
A 25-year-old primigravida at 39 weeks is admitted in established labour. Her cervix is 5 cm dilated, contractions are regular, and the fetal heart rate is normal. Four hours later, cervical dilatation is 6 cm, contractions remain inadequate, and there is no evidence of mechanical obstruction. Which intervention may be considered after appropriate obstetric reassessment?
20.
A 30-year-old woman at 33 weeks of pregnancy presents with suspected preterm prelabour rupture of membranes. She is afebrile, haemodynamically stable and has no uterine tenderness. Which examination is most appropriate initially to assess membrane rupture while reducing infection risk?
21.
A 36-year-old woman with a previous Caesarean section is admitted in spontaneous labour. She is counselled regarding the benefits and risks of attempting vaginal birth. The obstetrician explains that continuous fetal monitoring is important because changes in the fetal heart rate may provide an early indication of a serious complication. Which finding would most strongly warrant urgent assessment for uterine scar complications?
22.
A 30-year-old woman at 32 weeks of gestation is admitted with confirmed preterm prelabour rupture of membranes. Initially, she is afebrile with reassuring fetal assessment. Twelve hours later, her temperature rises to 38.5°C, she develops uterine tenderness, and the fetal heart rate becomes persistently elevated. Which is the most appropriate management principle?
23.
A 29-year-old primigravida at term has experienced regular uterine contractions for several hours. Despite apparently adequate contractions, cervical dilatation has stopped progressing. Examination suggests that the fetal head remains high in the pelvis. Which mechanism is an important possible cause of this abnormal labour progress?
24.
A 27-year-old primigravida at term has been in labour for several hours. Examination reveals marked fetal head moulding, increasing caput formation and failure of descent despite strong uterine contractions. The mother is exhausted, and fetal heart rate abnormalities are beginning to develop. Which is the most appropriate management decision?
25.
A 32-year-old multiparous woman is admitted with established labour at term. During assessment, the fetal heart rate becomes persistently abnormal, and vaginal examination reveals a prolapsed pulsating umbilical cord below the presenting part. The fetal head is high, and immediate vaginal birth is not feasible. Which is the most appropriate management principle?
26.
A 29-year-old woman at 41 weeks of gestation is admitted for induction of labour. Fetal assessment is reassuring, the presentation is cephalic, and there is no contraindication to vaginal delivery. Cervical assessment indicates an unfavourable cervix. Which intervention is most appropriate before attempting effective labour induction?
27.
A 30-year-old primigravida has been pushing for a prolonged period. The fetal head remains relatively high, the position is uncertain, and significant caput has developed. The fetal heart rate now shows persistent abnormalities. The obstetrician considers whether instrumental delivery is feasible. Which finding most strongly argues against an attempted vacuum delivery?
28.
A 26-year-old woman in active labour requests pain relief. She is anxious about opioid analgesia because of its possible effects on her baby. The obstetrician explains that systemic opioids may cross the placenta, particularly when administered close to delivery. Which neonatal complication is most relevant to this counselling?
29.
A 28-year-old woman undergoes Caesarean delivery for failure to progress in labour. On the second postoperative day, she develops fever, lower abdominal tenderness and offensive vaginal discharge. Her pulse is elevated, and examination reveals uterine tenderness. Which diagnosis best explains this postoperative presentation?
30.
A 28-year-old primigravida at 31 weeks of gestation presents with regular painful uterine contractions and progressive cervical dilatation. Her membranes are intact, fetal assessment is reassuring, and there is no fever or vaginal bleeding. The obstetric team decides to administer antenatal corticosteroids and considers short-term tocolysis. Which is the most appropriate rationale for using a tocolytic in this situation?
31.
A 33-year-old primigravida at 39 weeks of gestation presents in labour. Examination shows a transverse fetal lie, with the fetal shoulder presenting. The fetus is alive, and there is no immediate maternal instability. Which delivery method is generally most appropriate for a persistent transverse lie at term?
32.
A 33-year-old woman with a previous Caesarean section is being assessed for vaginal birth after Caesarean. Her previous operative record documents a classical vertical uterine incision involving the upper uterine segment. She is currently haemodynamically stable, and fetal assessment is reassuring. Which is the most appropriate delivery plan?
33.
A 34-year-old woman at 39 weeks undergoes an emergency Caesarean section because of suspected fetal compromise. She receives appropriate anaesthesia and delivers a live infant. In the recovery area, she becomes tachycardic and hypotensive, with increasing vaginal bleeding and a poorly contracted uterus. Which pathological process most directly explains her clinical deterioration?
34.
A 34-year-old woman with a twin pregnancy is admitted in labour at 37 weeks. Ultrasound confirms that the first twin is in cephalic presentation, and both fetuses are currently stable. Why does this pregnancy require additional intrapartum assessment compared with a singleton pregnancy?
35.
A 27-year-old pregnant woman at 30 weeks develops regular painful uterine contractions associated with progressive cervical dilatation. The obstetric team considers antenatal corticosteroids because premature delivery is possible. What is the primary fetal benefit of this treatment?
36.
A 26-year-old primigravida at 38 weeks of gestation presents with painful uterine contractions occurring every five minutes. She reports passage of blood-stained mucus. On vaginal examination, the cervix is 4 cm dilated and progressively effacing. Which finding most strongly confirms that she is in true labour?
37.
A 31-year-old multiparous woman at 38 weeks has a breech presentation. She has a previous uncomplicated vaginal birth and wishes to avoid Caesarean section. Ultrasound confirms a singleton fetus without major abnormalities. Which factor is most important when considering whether planned vaginal breech delivery is appropriate?
38.
A 31-year-old woman has a prolonged second stage of labour and subsequently requires forceps-assisted vaginal delivery. Following birth, she experiences significant vaginal bleeding despite a well-contracted uterus. Examination reveals a deep vaginal laceration. Which is the most appropriate interpretation of the cause of bleeding?
39.
A 28-year-old woman at 31 weeks of gestation is admitted with threatened preterm delivery. The obstetric team considers magnesium sulfate for fetal neuroprotection because delivery appears imminent. Which neonatal complication is this intervention primarily intended to reduce?
40.
A 27-year-old woman in active labour requests effective pain relief. She has no contraindications, and an epidural technique is being considered. What is the principal mechanism by which epidural analgesia reduces labour pain?
