50 High-Yield NORCET MCQs: Chapter - Labour

SECTION A: STAGES OF LABOUR (Q1-Q10)

Q1. The latent phase of the first stage of labour is considered prolonged in a nullipara when it exceeds:

A) 8 hours B) 14 hours C) 20 hours D) 24 hours

Answer: C) 20 hours The latent phase is variable but is usually less than 20 hours for a nullipara and 14 hours for a multipara. Beyond these limits it is "prolonged latent phase."

Q2. In the active phase of the first stage of labour, the minimum acceptable rate of cervical dilation in a nulliparous woman is:

A) 0.5 cm/hr B) 1.0 cm/hr C) 1.2 cm/hr D) 1.5 cm/hr

Answer: C) 1.2 cm/hr Nulliparous women dilate at least 1.2 cm/hr; multiparous women dilate at least 1.5 cm/hr in the active phase (Friedman's criteria).

Q3. The active phase of labour usually begins at a cervical dilation of:

A) 2-3 cm B) 4-5 cm C) 6-7 cm D) 8 cm

Answer: B) 4-5 cm The active phase occurs at about 4-5 cm cervical dilation and is the segment of rapid dilation not affected by sedation or conduction anesthesia.

Q4. The second stage of labour averages ___ minutes for multiparas and ___ minutes for nulliparas:

A) 10 min / 20 min B) 20 min / 50 min C) 30 min / 60 min D) 15 min / 45 min

Answer: B) 20 min / 50 min The second stage averages 20 minutes for multiparas and 50 minutes for nulliparas.

Q5. The third stage of labour is defined as:

A) Period from full dilation to delivery of baby B) Period from delivery of baby to delivery of placenta C) Period from onset of labour to full dilation D) First hour after delivery of placenta

Answer: B) Period from delivery of baby to delivery of placenta Third stage = from delivery of fetus to delivery of placenta. Fourth stage = first hour after placenta delivery.

Q6. A nulliparous woman has been pushing for 2.5 hours without an epidural. Fetal heart rate is normal and there is continued progress in descent. What is the MOST appropriate next step?

A) Immediate caesarean section B) Forceps delivery C) Continue pushing with close monitoring D) Vacuum extraction

Answer: C) Continue pushing with close monitoring Pushing for >2 hours without epidural or >3 hours with epidural in a nullipara should alert the practitioner to possible CPD, but pushing can continue longer if FHR is adequate and there is continued progress in descent.

Q7. The CORRECT order of cardinal movements of the fetal head during labour is:

A) Engagement → Descent → Flexion → Internal rotation → Extension → External rotation → Expulsion B) Descent → Engagement → Flexion → Internal rotation → Extension → External rotation → Expulsion C) Engagement → Flexion → Descent → Internal rotation → Extension → External rotation → Expulsion D) Engagement → Descent → Internal rotation → Flexion → Extension → External rotation → Expulsion

Answer: A) Engagement → Descent → Flexion → Internal rotation → Extension → External rotation → Expulsion The 7 cardinal movements: Engagement, Descent, Flexion, Internal rotation, Extension, External rotation, Expulsion. Flexion reduces the anteroposterior diameter to permit easier descent.

Q8. In the latent phase of labour, what is the MOST appropriate management for prolonged latent phase?

A) Immediate oxytocin augmentation B) Morphine injection (rest) C) Emergency LSCS D) Amniotomy

Answer: B) Morphine injection (rest) A prolonged latent phase can be treated with morphine in a hospital setting (therapeutic rest). Often this treatment accelerates transition to the active phase.

Q9. In a low-risk mother with normal labour, fetal heart auscultation in the ACTIVE phase should be done at minimum every:

A) 15 minutes B) 30 minutes C) 60 minutes D) 10 minutes

Answer: B) 30 minutes In low-risk mothers with normal labour, the fetal heart may be auscultated after a contraction every 30 minutes in the active phase. Frequency increases to every 15 minutes in higher-risk labours.

Q10. In the SECOND stage of labour, fetal heart should be auscultated and recorded every ___ minutes in high-risk pregnancies:

A) 5 minutes B) 10 minutes C) 15 minutes D) 20 minutes

Answer: B) 10 minutes The fetal heart should be auscultated every 15 minutes in normal low-risk pregnancies and every 10 minutes in higher-risk pregnancies during the second stage.

A) Confirming preterm labour B) Its high NEGATIVE predictive value (ruling out delivery in next 7-10 days) C) Its high POSITIVE predictive value D) Assessing fetal lung maturity

Answer: B) High negative predictive value Fetal fibronectin is used predominantly for its high negative predictive value - if negative, the woman will likely NOT deliver for at least 7-10 days. A positive result warrants closer surveillance.

Q14. Fetal fibronectin assessment in preterm labour should be performed BEFORE digital examination in women at:

A) 16-22 weeks B) 22-35 weeks C) 36-40 weeks D) Any gestation

Answer: B) 22-35 weeks In a woman at 22 to 35 weeks' gestation, before digital examination, assessment of the presence of fetal fibronectin should be determined.

A) Intact membranes B) Normal fetal heart rate C) Chorioamnionitis D) Gestational age 30 weeks

Answer: C) Chorioamnionitis Contraindications to stopping labour (tocolysis) include: chorioamnionitis, abruptio placentae, heavy vaginal bleeding, severe or chronic hypertension, and fetal demise.

Q18. Which simple intervention decreases the frequency of preterm contractions but does NOT reduce the rate of preterm birth?

A) Terbutaline B) Magnesium sulfate C) Hydration D) Nifedipine

Answer: C) Hydration Hydration appears to decrease the frequency of preterm contractions, but it does NOT decrease the rate of preterm birth.

Q21. The PRIMARY goal of labour monitoring is:

A) Documenting all vitals every 30 minutes B) Achieving delivery of a healthy infant from a healthy mother with as little trauma as possible C) Ensuring epidural analgesia for all patients D) Monitoring uterine contractions electronically

Answer: B) Achieving delivery of a healthy infant from a healthy mother with as little trauma as possible The primary goal of labour monitoring is to achieve delivery of a healthy infant from a healthy mother with as little trauma as possible (Creasy & Resnik).

Q22. The MOST important bedside figure bridging technology and patient expectations in the labour unit is:

A) Obstetrician B) Anesthesiologist C) Labour and delivery nurse D) Midwife

Answer: C) Labour and delivery nurse "Perhaps the most important figure in this entire scenario is the bedside nurse in the labour and delivery unit" - Creasy & Resnik.

A) 1:3 B) 1:2 C) 1:1 D) 1:4

Answer: C) 1:1 A one-to-one nurse-patient ratio is implied for patients in active labour to fulfill monitoring, communication, and emotional support goals.

Q24. Flexion of the fetal head during cardinal movements is important because it:

A) Facilitates internal rotation B) Diminishes the anteroposterior diameter of the head, permitting easier descent C) Allows engagement at the pelvic brim D) Facilitates extension at the outlet

Answer: B) Diminishes the anteroposterior diameter of the head Flexion of the fetal head diminishes its anteroposterior diameter and permits easier descent through the birth canal.

Q25. The "latent phase" of the first stage of labour is characterized by:

A) Rapid cervical dilation at 1.2 cm/hr B) Variable length, little dilation, but cervical effacement and softening C) Rupture of membranes D) Onset of bearing-down efforts

Answer: B) Variable length, little dilation, cervical effacement and softening The latent phase has little cervical dilation but involves cervical preparation - changes in collagen/connective tissue, effacement, and anterior positioning of the cervix.

Q26. Which traditional obstetric practice has been found NOT beneficial and is largely abandoned?

A) Continuous electronic fetal monitoring B) Perineal shave and enema C) IV fluid administration D) Intrapartum antibiotic prophylaxis

Answer: B) Perineal shave and enema Traditional hospital practices such as the perineal shave, enemas, and isolation of the patient from family and friends have been found to NOT be beneficial.

Answer: C) Left occiput anterior (LOA) LOA (Left Occiput Anterior) is the most common fetal position at term. The occiput faces the left anterior quadrant of the maternal pelvis.

Q36. A woman in active labour has FHR decelerations on auscultation. The MOST appropriate next step is:

A) Administer tocolytics B) Proceed to emergency LSCS immediately C) Increase frequency of auscultation or commence continuous EFM D) Administer oxygen and continue routine monitoring

Answer: C) Increase auscultation frequency or commence continuous EFM FHR decelerations should prompt even more frequent auscultation or continuous EFM to better characterize the deceleration pattern.

Q37. Conduction anesthesia given in which phase of labour can prolong or arrest labour progress?

A) Active phase B) Second stage C) Latent phase D) Transition phase

Answer: C) Latent phase Conduction anesthesia given in the LATENT phase may prolong or arrest progress. The active phase is NOT affected by sedation or conduction anesthesia.

A) Tocolysis with magnesium sulfate only B) Antibiotic therapy and urinary culture C) Immediate delivery D) Amniocentesis for culture

Answer: B) Antibiotic therapy and urinary culture Urinalysis and culture are obtained, and antibiotic therapy is instituted if the urinalysis is suspicious for infection in preterm labour patients.

Q39. Which of the following is the PRIMARY mechanism by which ambulation helps in labour?

A) Reduces FHR baseline B) Allows gravity to aid descent and is physiologically beneficial, improving maternal comfort C) Speeds cervical dilation by 2 cm/hr D) Reduces risk of postpartum haemorrhage

Answer: B) Aids descent physiologically and improves maternal comfort More liberal use of ambulation and positions of comfort in labour and delivery have been found to be physiologically beneficial. Auscultation rather than continuous EFM allows this mobility.

Q40. "Dysfunctional labour" most often refers to:

A) Failure of second stage to progress beyond 10 minutes B) Abnormality in the rate of cervical dilation or fetal descent during the active phase or second stage C) Failure of placenta to deliver within 30 minutes D) Absence of labour at 42 weeks

Answer: B) Abnormality in rate of cervical dilation or fetal descent Dysfunctional labour refers to abnormalities in the rate of cervical dilation (active phase arrest or protraction) or abnormal fetal descent during the active phase or second stage.

SECTION E: INDUCTION OF LABOUR & SPECIAL TOPICS (Q41-Q50)

Q41. Which cervical ripening agent acts by causing uterine contractions AND cervical softening?

A) Magnesium sulfate B) Prostaglandin E2 (dinoprostone/misoprostol) C) Terbutaline D) Oxytocin

Answer: B) Prostaglandin E2 (dinoprostone/misoprostol) Prostaglandins (PGE2 agents like dinoprostone, misoprostol) both ripen the cervix (softening, effacement) and stimulate uterine contractions, making them ideal for induction.

Q42. The Bishop score is used to assess:

A) Fetal wellbeing before induction B) Cervical favourability before induction of labour C) Risk of shoulder dystocia D) Degree of engagement of fetal head

Answer: B) Cervical favourability before induction The Bishop score evaluates cervical dilation, effacement, consistency, position, and fetal station. A score ≥8 indicates a favourable cervix for induction.

Q43. The MOST reliable sign of placental separation during the third stage of labour is:

A) Sudden maternal urge to push B) Lengthening of the umbilical cord and a gush of blood C) Return of uterine contractions D) Maternal bradycardia

Answer: B) Lengthening of the cord and a gush of blood The signs of placental separation include: lengthening of the umbilical cord, a gush of blood, the uterus becoming globular and firm (Calkin's sign), and the uterus rising in the abdomen.

Q44. Active management of the third stage of labour (AMTSL) primarily involves:

A) Maternal pushing efforts B) Oxytocin administration, controlled cord traction, and uterine massage C) Prophylactic ergometrine alone D) Manual removal of placenta in all cases

Answer: B) Oxytocin, controlled cord traction, and uterine massage AMTSL involves: uterotonic (oxytocin 10 IU IM) immediately after delivery, controlled cord traction, and uterine massage - this reduces PPH risk.

Q45. The MOST common cause of primary postpartum haemorrhage (PPH) is:

A) Retained placenta B) Genital tract lacerations C) Uterine atony D) Coagulopathy

Answer: C) Uterine atony Uterine atony (failure of uterus to contract after delivery) accounts for approximately 70-80% of cases of primary PPH. Remember the "4 Ts": Tone (most common), Tissue, Trauma, Thrombin.

Q46. A primigravida at 39 weeks is admitted in labour. On examination: cervix 3 cm dilated, 40% effaced, head at -2 station. This woman is in:

A) Active phase of first stage B) Latent phase of first stage C) Second stage D) Transition phase

Answer: B) Latent phase of first stage The latent phase involves minimal dilation with cervical preparation (effacement, softening). The active phase begins at approximately 4-5 cm dilation. At 3 cm with 40% effacement, this is the latent phase.

Q47. Which of the following fetal monitoring findings during active labour is considered NON-REASSURING?

A) Baseline FHR 140 bpm with moderate variability B) Accelerations with fetal movement C) Variable decelerations with loss of variability D) Early decelerations corresponding to contractions

Answer: C) Variable decelerations with loss of variability Variable decelerations combined with loss of beat-to-beat variability is a non-reassuring (Category II/III) pattern suggesting possible fetal acidosis. Early decelerations with normal variability are benign.

Q48. A multiparous woman is in labour. She has been in active phase for 3 hours with no cervical change on serial exams. Contractions are adequate. This is called:

A) Prolonged latent phase B) Active phase protraction C) Active phase arrest D) Secondary arrest of dilation

Answer: C) Active phase arrest (also called Secondary arrest of dilation) Active phase arrest (or secondary arrest of dilation) is defined as no cervical change for 2 or more hours in the active phase with adequate uterine contractions. Management includes amniotomy and/or oxytocin augmentation.

Q49. Which of the following correctly describes the latent phase limit for MULTIPAROUS women?

A) Less than 12 hours B) Less than 14 hours C) Less than 20 hours D) Less than 18 hours

Answer: B) Less than 14 hours The latent phase is usually less than 20 hours for a NULLIPARA and less than 14 hours for a MULTIPARA. Beyond these limits, it is termed "prolonged latent phase."

Q50. During an emergency delivery in the ED, which finding on fetal ultrasound is MOST critical before delivery?

A) Placental grading B) Amniotic fluid index alone C) Fetal viability, lie, and presentation D) Umbilical artery Doppler

Answer: C) Fetal viability, lie, and presentation Ultrasound provides crucial information regarding pending delivery, including fetal viability, lie, and presentation - essential for deciding mode of delivery and anticipating complications.
