**Q1. Which of the following best distinguishes TRUE labour from FALSE labour?**

A. Regular contractions that increase in frequency and intensity  
B. Contractions that diminish with walking  
C. Pain confined to the lower abdomen only  
D. Absence of cervical effacement  

**Answer: A. Regular contractions that increase in frequency and intensity**  
**Explanation:** True labour is characterised by regular uterine contractions that progressively increase in frequency, duration, and intensity, accompanied by cervical effacement and dilation. False (Braxton Hicks) contractions are irregular, do not intensify, and often subside with ambulation or rest.

---

**Q2. The normal fetal heart rate (FHR) range during labour is:**

A. 100–140 bpm  
B. 110–160 bpm  
C. 120–180 bpm  
D. 90–150 bpm  

**Answer: B. 110–160 bpm**  
**Explanation:** The baseline FHR in a term fetus is normally 110–160 bpm. A rate below 110 bpm is bradycardia; above 160 bpm is tachycardia. Continuous electronic fetal monitoring or intermittent auscultation is used in labour to detect deviations from this normal range.

---

**Q3. Effacement of the cervix refers to:**

A. Opening of the cervical os  
B. Softening and shortening (thinning) of the cervix  
C. Descent of the presenting part  
D. Rotation of the fetal head  

**Answer: B. Softening and shortening (thinning) of the cervix**  
**Explanation:** Effacement is the process by which the cervix shortens and thins out (0%–100%). It is distinct from dilation (opening of the cervical os). In primigravidae, effacement typically precedes dilation; in multigravidae, both may occur simultaneously.

---

**Q4. The FIRST stage of labour begins with:**

A. Complete dilation of the cervix  
B. Regular uterine contractions with cervical changes and ends with full cervical dilation  
C. Rupture of membranes  
D. Birth of the baby  

**Answer: B. Regular uterine contractions with cervical changes and ends with full cervical dilation**  
**Explanation:** The first stage of labour starts with the onset of regular uterine contractions causing progressive cervical change and ends when the cervix is fully dilated (10 cm). It is the longest stage and is subdivided into the latent phase and active phase.

---

**Q5. The normal duration of the active phase of the first stage of labour in a primigravida is:**

A. Less than 4 hours  
B. Up to 20 hours total first stage (active phase typically 6–12 hours)  
C. Up to 30 hours  
D. 2–4 hours only  

**Answer: B. Up to 20 hours total first stage (active phase typically 6–12 hours)**  
**Explanation:** In a primigravida, the total first stage of labour may last up to 20 hours (latent + active). The active phase (from 4–6 cm to 10 cm) typically takes 6–12 hours. In a multigravida, it is shorter — up to 14 hours total. Progress is at least 1 cm/hr in the active phase.

---

**Q6. The SECOND stage of labour is:**

A. From onset of contractions to full dilation  
B. From full cervical dilation to delivery of the placenta  
C. From full cervical dilation to delivery of the baby  
D. From delivery of the baby to 1 hour postpartum  

**Answer: C. From full cervical dilation to delivery of the baby**  
**Explanation:** The second stage begins at complete cervical dilation (10 cm) and ends with the birth of the baby. Its duration is up to 2 hours in primigravidae and up to 1 hour in multigravidae (longer if epidural analgesia is used — up to 3 hours and 2 hours respectively).

---

**Q7. During the THIRD stage of labour, the nurse should observe for signs of placental separation. Which is NOT a sign of placental separation?**

A. Gush of blood from the vagina  
B. Lengthening of the umbilical cord  
C. Fundus becomes globular and firm  
D. Cervical os begins to dilate further  

**Answer: D. Cervical os begins to dilate further**  
**Explanation:** Signs of placental separation include: the uterus becomes globular and firm, a sudden gush of blood, lengthening of the umbilical cord, and the fundus rises in the abdomen. Dilation of the cervix does not indicate placental separation.

---

**Q8. Active Management of the Third Stage of Labour (AMTSL) includes all EXCEPT:**

A. Oxytocin 10 IU IM within 1 minute of baby's birth  
B. Controlled cord traction  
C. Uterine massage after placenta delivery  
D. Immediate breastfeeding to release oxytocin  

**Answer: D. Immediate breastfeeding to release oxytocin**  
**Explanation:** AMTSL consists of three components: (1) uterotonic drug (oxytocin 10 IU IM) within 1 minute of birth, (2) controlled cord traction (Brandt-Andrews method), and (3) uterine massage after placenta delivery. Breastfeeding, while beneficial, is not part of the formal AMTSL protocol.

---

**Q9. The APGAR score is assessed at:**

A. 1 minute and 5 minutes after birth  
B. 2 minutes and 10 minutes after birth  
C. 1 minute and 10 minutes after birth  
D. Immediately and 5 minutes after birth  

**Answer: A. 1 minute and 5 minutes after birth**  
**Explanation:** The APGAR score is routinely assessed at 1 minute and 5 minutes after birth. If the score is less than 7 at 5 minutes, additional assessments are made at 10, 15, and 20 minutes. Each of the 5 criteria (appearance, pulse, grimace, activity, respiration) is scored 0–2, maximum total = 10.

---

**Q10. A neonate has the following APGAR findings at 1 minute: Heart rate 90 bpm, slow irregular respiration, some flexion of extremities, grimace on stimulation, body pink with blue extremities. What is the APGAR score?**

A. 5  
B. 6  
C. 7  
D. 4  

**Answer: B. 6**  
**Explanation:** Scoring: Heart rate 90 bpm = 1 (below 100), Respiration irregular = 1, Muscle tone some flexion = 1, Reflex grimace = 1, Colour body pink/blue extremities (acrocyanosis) = 1. Total = 5. Wait — let us recount: HR 90 = 1, Resp slow irregular = 1, Tone some flexion = 1, Grimace = 1, Colour acrocyanosis = 1. Total = 5. The correct answer is actually A (5), based on this breakdown. However presented option B is commonly tested; the question tests the ability to add 5 criteria each scoring 0–2.  
*(Corrected: Answer is A = 5)*

**Answer: A. 5**  
**Explanation:** Each criterion: HR < 100 = 1, Respirations slow/irregular = 1, Tone some flexion = 1, Reflex grimace = 1, Colour acrocyanosis = 1. Total = 5. A score of 4–6 indicates moderate depression, requiring stimulation and supplemental oxygen.

---

**Q11. Which medication is given to accelerate fetal lung maturity in preterm labour between 24–34 weeks of gestation?**

A. Terbutaline 0.25 mg SC  
B. Betamethasone 12 mg IM every 24 hours for 2 doses  
C. Magnesium sulfate 4 g IV bolus  
D. Indomethacin 50 mg orally  

**Answer: B. Betamethasone 12 mg IM every 24 hours for 2 doses**  
**Explanation:** Antenatal corticosteroids — betamethasone 12 mg IM every 24 hours for 2 doses (or dexamethasone 6 mg IM every 12 hours for 4 doses) — are administered between 24–34 weeks gestation to accelerate fetal lung maturity by stimulating surfactant production, reducing the risk of RDS, IVH, and NEC.

---

**Q12. The Bishop Score is used to assess:**

A. Fetal well-being in labour  
B. Cervical readiness (favourability) for induction of labour  
C. Risk of postpartum haemorrhage  
D. Duration of second stage  

**Answer: B. Cervical readiness (favourability) for induction of labour**  
**Explanation:** The Bishop Score evaluates cervical dilation, effacement, consistency, position (anterior/mid/posterior), and fetal station. A score ≥8 indicates a favourable cervix suitable for induction. A score ≤6 indicates an unfavourable cervix, and cervical ripening agents (prostaglandins, balloon catheter) are used first.

---

**Q13. The mechanism of labour occurs in a specific sequence. What is the FIRST cardinal movement?**

A. Flexion  
B. Descent  
C. Engagement  
D. Internal rotation  

**Answer: C. Engagement**  
**Explanation:** The cardinal movements of labour in sequence are: (1) Engagement, (2) Descent, (3) Flexion, (4) Internal rotation, (5) Extension, (6) External rotation (restitution), (7) Expulsion. Engagement occurs when the widest diameter of the fetal head (biparietal diameter) passes through the pelvic inlet.

---

**Q14. In a vertex presentation, internal rotation of the fetal head results in the occiput rotating to which position?**

A. Posterior (toward the sacrum)  
B. Anterior (toward the pubic symphysis)  
C. Lateral (transverse)  
D. No rotation occurs  

**Answer: B. Anterior (toward the pubic symphysis)**  
**Explanation:** During internal rotation, the fetal occiput rotates from the transverse position to the anterior position (under the pubic symphysis — occiput anterior). This aligns the longest diameter of the fetal head with the anteroposterior diameter of the pelvic outlet, facilitating delivery.

---

**Q15. The Nitrazine test is used to detect:**

A. Group B Streptococcus colonisation  
B. Rupture of membranes (amniotic fluid)  
C. Fetal fibronectin  
D. Preeclampsia  

**Answer: B. Rupture of membranes (amniotic fluid)**  
**Explanation:** Amniotic fluid is alkaline (pH 7.0–7.5), while normal vaginal secretions are acidic (pH 4.5–5.5). Nitrazine paper turns blue-green to blue in the presence of amniotic fluid (alkaline), indicating rupture of membranes. Blood, semen, and cervical mucus can cause false positives.

---

**Q16. Ferning (arborisation) pattern on microscopy of vaginal fluid confirms:**

A. Infection of amniotic fluid  
B. Presence of amniotic fluid (ruptured membranes)  
C. Presence of blood  
D. Fetal fibronectin  

**Answer: B. Presence of amniotic fluid (ruptured membranes)**  
**Explanation:** When amniotic fluid dries on a glass slide, it forms a characteristic fern-like (arborisation) pattern due to its high sodium chloride and protein content. This ferning pattern confirms rupture of membranes. Vaginal fluid without ferning suggests intact membranes.

---

**Q17. PROM stands for:**

A. Premature Rupture Of Membranes before labour begins at or after 37 weeks  
B. Premature Rupture Of Membranes before labour at any gestational age  
C. Pre-labour Rupture Of Membranes before 37 weeks  
D. Prolonged Rupture Of Membranes  

**Answer: A. Premature Rupture Of Membranes before labour begins at or after 37 weeks**  
**Explanation:** PROM = Premature Rupture of Membranes at ≥37 weeks before labour onset. PPROM = Preterm Premature Rupture of Membranes at <37 weeks. Prolonged ROM means membranes have been ruptured >18 hours, which increases the risk of chorioamnionitis and requires GBS prophylaxis.

---

**Q18. A laboring patient suddenly develops variable FHR decelerations. The MOST likely cause is:**

A. Head compression during contractions  
B. Uteroplacental insufficiency  
C. Umbilical cord compression  
D. Fetal sleep cycle  

**Answer: C. Umbilical cord compression**  
**Explanation:** Variable decelerations are abrupt (onset to nadir <30 seconds), vary in shape, timing, and duration, and are caused by umbilical cord compression. They may occur with cord prolapse, nuchal cord, or oligohydramnios. Early decelerations are caused by head compression; late decelerations indicate uteroplacental insufficiency.

---

**Q19. Late decelerations of fetal heart rate are associated with:**

A. Head compression  
B. Umbilical cord compression  
C. Uteroplacental insufficiency  
D. Fetal sleeping pattern  

**Answer: C. Uteroplacental insufficiency**  
**Explanation:** Late decelerations begin after the peak of the contraction and return to baseline after the contraction ends (onset-to-nadir ≥30 seconds after peak). They indicate uteroplacental insufficiency and are associated with maternal hypotension, excessive oxytocin use, placental abruption, and postmaturity. They are non-reassuring and require immediate intervention.

---

**Q20. The FIRST nursing intervention when a late deceleration is noted on the fetal monitor is:**

A. Prepare for emergency cesarean section  
B. Administer oxygen and reposition the mother to left lateral  
C. Increase the oxytocin infusion rate  
D. Perform amnioinfusion  

**Answer: B. Administer oxygen and reposition the mother to left lateral**  
**Explanation:** The immediate nursing response to late decelerations is: (1) reposition mother to left lateral decubitus (relieves aortocaval compression), (2) administer oxygen via face mask at 8–10 L/min, (3) discontinue oxytocin if infusing, (4) increase IV fluids, and (5) notify the physician. These measures improve uteroplacental perfusion.

---

**Q21. During shoulder dystocia, the McRoberts manoeuvre involves:**

A. Applying suprapubic pressure  
B. Hyperflexion of the mother's thighs against her abdomen  
C. Rotating the fetal shoulders to the oblique diameter  
D. Delivery of the posterior arm  

**Answer: B. Hyperflexion of the mother's thighs against her abdomen**  
**Explanation:** The McRoberts manoeuvre is the FIRST-LINE intervention for shoulder dystocia. It involves sharply flexing the mother's thighs onto her abdomen, which flattens the lumbar lordosis, rotates the pubic symphysis superiorly, and increases the functional diameter of the pelvis, freeing the impacted shoulder. It is often combined with suprapubic pressure.

---

**Q22. Primary postpartum haemorrhage (PPH) is defined as blood loss of:**

A. ≥300 mL after vaginal delivery within 24 hours  
B. ≥500 mL after vaginal delivery within 24 hours  
C. ≥800 mL after any delivery  
D. ≥250 mL within 6 hours  

**Answer: B. ≥500 mL after vaginal delivery within 24 hours**  
**Explanation:** Primary PPH is defined as blood loss ≥500 mL after vaginal delivery or ≥1000 mL after cesarean delivery, occurring within 24 hours of birth. Secondary PPH occurs between 24 hours and 12 weeks postpartum. The '4 Ts' causes are: Tone (uterine atony — most common, 70–80%), Trauma, Tissue (retained placenta), Thrombin (coagulopathy).

---

**Q23. Uterine atony is the MOST common cause of PPH. The FIRST-LINE uterotonic agent used is:**

A. Methylergometrine 0.2 mg IM  
B. Misoprostol 600 mcg sublingual  
C. Oxytocin 10 IU IV/IM  
D. Carboprost 250 mcg IM  

**Answer: C. Oxytocin 10 IU IV/IM**  
**Explanation:** Oxytocin (10 IU IM or slow IV) is the first-line uterotonic for both prevention and treatment of PPH. It causes sustained uterine contractions. Methylergometrine is second-line but contraindicated in hypertension. Misoprostol is used when oxytocin is unavailable. Carboprost is used for refractory atony (contraindicated in asthma).

---

**Q24. A mediolateral episiotomy is made at:**

A. The midline posteriorly toward the anus  
B. At a 45-degree angle to the right or left of the midline  
C. Parallel to the uterine axis  
D. Transversely across the perineum  

**Answer: B. At a 45-degree angle to the right or left of the midline**  
**Explanation:** A mediolateral episiotomy is incised at a 45-degree angle to the midline (usually toward the right). It is associated with less risk of extension into the anal sphincter compared to the midline episiotomy, which is cut along the median raphe. However, mediolateral episiotomies are associated with more blood loss and slower healing.

---

**Q25. Which station indicates that the presenting part is at the level of the ischial spines?**

A. Station +2  
B. Station -2  
C. Station 0  
D. Station +1  

**Answer: C. Station 0**  
**Explanation:** Station describes the relationship of the presenting part to the ischial spines. Station 0 = at the level of the ischial spines (engaged). Negative stations (-1 to -5) indicate the presenting part is above the spines (not yet engaged). Positive stations (+1 to +5) indicate the presenting part is below the spines (in the pelvis, progressing toward delivery).

---

**Q26. LOA fetal position means:**

A. Left Occipital Anterior — occiput pointing to the left anterior of the maternal pelvis  
B. Left Occiput Abducted  
C. Lower Occipital Area  
D. Left Oblique Axis  

**Answer: A. Left Occipital Anterior — occiput pointing to the left anterior of the maternal pelvis**  
**Explanation:** Fetal position is described by the relationship of the fetal denominator (occiput in vertex, sacrum in breech, chin in face) to the maternal pelvis quadrants (Left/Right, Anterior/Posterior/Transverse). LOA is the most common and most favourable position for vaginal delivery. The sequence: side of pelvis (L/R) + denominator (O for occiput) + quadrant (A/P/T).

---

**Q27. A frank breech presentation means:**

A. Feet are the presenting part  
B. Both feet and buttocks are presenting  
C. Buttocks are presenting with hips flexed and knees extended (legs alongside the body)  
D. One foot is presenting  

**Answer: C. Buttocks are presenting with hips flexed and knees extended (legs alongside the body)**  
**Explanation:** In a frank breech, the hips are flexed and the knees are extended, so the buttocks alone present at the cervix (the legs are splinted upward alongside the fetal trunk). It is the most common type of breech presentation (~65–70%). Complete breech has hips and knees both flexed; footling breech has one or both feet presenting.

---

**Q28. The fourth stage of labour refers to:**

A. Delivery of the placenta  
B. The first 1–2 hours after delivery of the placenta  
C. The period from birth to 24 hours postpartum  
D. Active pushing phase  

**Answer: B. The first 1–2 hours after delivery of the placenta**  
**Explanation:** The fourth stage of labour is the immediate postpartum period — the first 1–2 hours after delivery of the placenta. This is a critical time for maternal physiological adjustment, uterine involution, and monitoring for early PPH. Vital signs, uterine tone, vaginal bleeding, bladder status, and perineum are assessed every 15 minutes during this period.

---

**Q29. Oxytocin for induction of labour is typically administered:**

A. Intramuscularly every 4 hours  
B. As a diluted IV infusion, starting at a low rate and titrating upward  
C. As a vaginal gel  
D. Orally in tablet form  

**Answer: B. As a diluted IV infusion, starting at a low rate and titrating upward**  
**Explanation:** Oxytocin for labour induction/augmentation is given as a continuous IV infusion (typically 10–20 IU in 500–1000 mL NS or D5W), starting at 0.5–1 mU/min and increasing every 15–40 minutes until adequate contractions are established. Continuous electronic FHR and contraction monitoring are mandatory during oxytocin infusion.

---

**Q30. A cord prolapse is an obstetric emergency. The FIRST nursing action is:**

A. Prepare for immediate cesarean section  
B. Call for help and manually elevate the presenting part off the cord  
C. Push the cord back into the uterus  
D. Place the mother in the supine position  

**Answer: B. Call for help and manually elevate the presenting part off the cord**  
**Explanation:** The immediate priority in cord prolapse is to relieve compression on the prolapsed cord: place the mother in knee-chest or Trendelenburg position, manually elevate the presenting part with a gloved hand to relieve cord compression, keep the cord warm and moist, administer oxygen, and prepare for emergency cesarean section. Never attempt to replace the cord.

---

**Q31. Tocolysis in preterm labour aims to:**

A. Induce contractions  
B. Suppress uterine contractions to delay preterm birth  
C. Ripen the cervix  
D. Stimulate fetal lung maturity directly  

**Answer: B. Suppress uterine contractions to delay preterm birth**  
**Explanation:** Tocolysis is the pharmacological inhibition of uterine contractions to delay preterm birth, primarily to allow time for corticosteroid administration and maternal transfer to a tertiary centre. Common tocolytics include nifedipine (calcium channel blocker), indomethacin (COX inhibitor), magnesium sulfate, and terbutaline (beta-2 agonist).

---

**Q32. Magnesium sulfate toxicity is monitored by assessing:**

A. Blood pressure and temperature  
B. Urine output, deep tendon reflexes, and respiratory rate  
C. Fetal heart rate only  
D. Blood glucose levels  

**Answer: B. Urine output, deep tendon reflexes, and respiratory rate**  
**Explanation:** Early signs of magnesium sulfate toxicity include loss of deep tendon reflexes (DTRs). The nurse monitors: urine output (maintain ≥25–30 mL/hr), respiratory rate (must remain ≥12–14/min), and DTRs (should be present). Therapeutic levels are 4–7 mEq/L. The antidote is calcium gluconate 1 g IV.

---

**Q33. Which type of fetal deceleration is BENIGN and caused by head compression during contractions?**

A. Variable decelerations  
B. Late decelerations  
C. Early decelerations  
D. Prolonged decelerations  

**Answer: C. Early decelerations**  
**Explanation:** Early decelerations mirror the contraction — they begin with the onset of the contraction and return to baseline by the end of the contraction (uniform shape, gradual onset). They are caused by vagal stimulation from fetal head compression and are considered benign, not requiring intervention.

---

**Q34. The process by which the fetal head adapts to the shape of the pelvis by overlapping of skull bones is called:**

A. Molding  
B. Engagement  
C. Flexion  
D. Caput succedaneum  

**Answer: A. Molding**  
**Explanation:** Molding is the temporary alteration in shape of the fetal skull as the bones overlap at the suture lines to accommodate to the maternal pelvis during labour. It usually resolves within 1–2 days after birth. Caput succedaneum is diffuse scalp edema from pressure, also common after vaginal delivery.

---

**Q35. In a normal labour, the frequency of uterine contractions in the active phase should be:**

A. 1–2 contractions in 10 minutes  
B. 3–5 contractions in 10 minutes  
C. 6–8 contractions in 10 minutes  
D. 1 contraction every 30 minutes  

**Answer: B. 3–5 contractions in 10 minutes**  
**Explanation:** Adequate uterine activity in active labour is generally defined as 3–5 contractions per 10 minutes, each lasting 40–60 seconds with moderate to strong intensity. Tachysystole (>5 contractions in 10 minutes) is abnormal and associated with fetal hypoxia, often caused by excess oxytocin.

---

**Q36. A prolonged latent phase of labour in a primigravida is defined as lasting more than:**

A. 8 hours  
B. 20 hours  
C. 12 hours  
D. 24 hours  

**Answer: B. 20 hours**  
**Explanation:** A prolonged latent phase is defined as >20 hours in a primigravida and >14 hours in a multigravida. Management options include therapeutic rest (morphine sedation), augmentation with oxytocin, or amniotomy. The latent phase extends from the onset of regular contractions to approximately 4–6 cm dilation.

---

**Q37. Pudendal nerve block provides analgesia to:**

A. Lower uterine segment and cervix  
B. Perineum, vulva, and lower vagina  
C. Entire uterus and abdomen  
D. Spinal cord from T10 to L1  

**Answer: B. Perineum, vulva, and lower vagina**  
**Explanation:** A pudendal nerve block anesthetizes the pudendal nerve (S2–S4), providing analgesia to the perineum, vulva, clitoris, and lower vagina. It is particularly useful for second-stage pain, episiotomy repair, and low-outlet forceps delivery. It does not relieve contraction pain (uterine pain is transmitted via T10–L1).

---

**Q38. Which presentation is associated with the highest risk of cord prolapse?**

A. Vertex (cephalic) presentation  
B. Frank breech  
C. Shoulder presentation (transverse lie)  
D. Left occiput anterior  

**Answer: C. Shoulder presentation (transverse lie)**  
**Explanation:** Cord prolapse risk is highest when there is a poor fit between the presenting part and the lower uterine segment/cervix. Transverse lie/shoulder presentation carries the greatest risk (~20%), followed by footling breech (>5%), and complete breech. Frank breech and vertex presentations have the lowest risk due to better fitting.

---

**Q39. The 'show' (bloody show) in early labour is caused by:**

A. Rupture of the amniotic sac  
B. Expulsion of the cervical mucus plug mixed with blood as the cervix begins to efface and dilate  
C. Placental separation  
D. Uterine contraction tearing the decidua  

**Answer: B. Expulsion of the cervical mucus plug mixed with blood as the cervix begins to efface and dilate**  
**Explanation:** Bloody show is the passage of blood-tinged mucus from the cervix, resulting from expulsion of the mucus plug (operculum) as the cervix softens, effaces, and begins to dilate. It may occur hours to days before labour begins and is a sign of impending labour.

---

**Q40. In precipitate labour, delivery occurs within:**

A. Less than 6 hours  
B. Less than 3 hours from onset of labour  
C. Less than 1 hour  
D. Less than 12 hours  

**Answer: B. Less than 3 hours from onset of labour**  
**Explanation:** Precipitate labour is abnormally rapid labour and delivery completed within 3 hours of onset. It is associated with risks to the mother (cervical, vaginal, and perineal lacerations; PPH) and the neonate (trauma, intracranial haemorrhage from rapid head compression/decompression, and potential unattended delivery complications).

---

**Q41. Which of the following is a contraindication to the use of oxytocin for induction of labour?**

A. Post-term pregnancy (>41 weeks)  
B. Placenta previa  
C. PROM at term  
D. Oligohydramnios  

**Answer: B. Placenta previa**  
**Explanation:** Placenta previa (where the placenta covers the cervical os) is an absolute contraindication to labour induction because uterine contractions and cervical dilation would cause catastrophic haemorrhage. Other contraindications include transverse fetal lie, prior classical uterine incision, active genital herpes, and umbilical cord prolapse.

---

**Q42. During the second stage of labour, the nurse notes the fetal head is visible at the vaginal introitus with each push but recedes between pushes. This is called:**

A. Crowning  
B. Engagement  
C. Bulging  
D. Caput succedaneum  

**Answer: A. Crowning**  
*Clarification: The described scenario (visible with push, recedes between) is actually NOT crowning. Crowning is when the fetal head remains visible between contractions without receding. The described scenario is just head on view during pushing.*  

**Corrected Answer: The correct term for the head being visible and not receding is Crowning. When the head is visible only with pushing and recedes between contractions, no standard single term applies — but crowning is when it no longer recedes.**  
**Explanation:** Crowning occurs when the largest diameter of the fetal head distends the vulva and the head no longer recedes between contractions. At this point, the birth attendant supports the perineum to control the speed of delivery and prevent perineal lacerations.

---

**Q43. The placenta is normally delivered within how many minutes after birth of the baby?**

A. 5 minutes  
B. 5–30 minutes  
C. 45–60 minutes  
D. More than 60 minutes  

**Answer: B. 5–30 minutes**  
**Explanation:** The third stage of labour (placental delivery) normally lasts 5–30 minutes. If the placenta is not delivered within 30 minutes (some guidelines say 60 minutes), it is called a retained placenta, which is a leading cause of PPH and requires manual removal under anesthesia.

---

**Q44. Fetal fibronectin (fFN) test is valuable in preterm labour because:**

A. A positive result confirms preterm labour will occur  
B. A negative result has high negative predictive value — delivery unlikely within 7–14 days  
C. It measures cervical dilation indirectly  
D. It detects Group B Streptococcus  

**Answer: B. A negative result has high negative predictive value — delivery unlikely within 7–14 days**  
**Explanation:** Fetal fibronectin is a glycoprotein found at the chorion-decidua interface. Its presence in cervicovaginal secretions between 22–34 weeks is associated with increased preterm delivery risk. The test's main clinical value is its high negative predictive value (>95%) — a negative fFN means delivery is very unlikely within the next 7–14 days, avoiding unnecessary interventions.

---

**Q45. What is the normal duration of uterine contractions in active labour?**

A. 15–20 seconds  
B. 30–40 seconds  
C. 45–90 seconds  
D. 2–3 minutes  

**Answer: C. 45–90 seconds**  
**Explanation:** In active labour, uterine contractions typically last 45–90 seconds. Contractions in early labour are shorter (20–30 seconds) and mild. Contractions lasting >90 seconds (hypertonic) or continuous contractions without relaxation are abnormal (tetanic) and can compromise fetal oxygenation.

---

**Q46. Which of the following is the CORRECT sequence of the cardinal movements of labour?**

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

**Answer: B. Engagement → Descent → Flexion → Internal rotation → Extension → External rotation → Expulsion**  
**Explanation:** The 7 cardinal movements in order: (1) Engagement (BPD passes pelvic inlet), (2) Descent (throughout labour), (3) Flexion (chin to chest, smaller diameter presents), (4) Internal rotation (occiput to anterior), (5) Extension (head delivered under pubic arch), (6) External rotation/restitution (head aligns with shoulders), (7) Expulsion (anterior then posterior shoulder delivered).

**Q47. A patient in labour is Group B Streptococcus (GBS) positive on antenatal culture. The nursing action is to ensure:**

A. Cesarean section is planned  
B. IV antibiotic prophylaxis (penicillin G) is administered at least 4 hours before delivery  
C. Oral antibiotics are given for 7 days  
D. The baby receives vaccination at birth  

**Answer: B. IV antibiotic prophylaxis (penicillin G) is administered at least 4 hours before delivery**  
**Explanation:** GBS prophylaxis is administered intrapartum (during labour) to prevent neonatal early-onset GBS sepsis. Penicillin G IV is the drug of choice (ampicillin as alternative; clindamycin for penicillin allergy). Prophylaxis is most effective when given ≥4 hours before delivery. All GBS-positive women should receive it at the onset of labour or rupture of membranes.

**Q48. The Brandt-Andrews technique is used during:**

A. Second stage of labour to deliver the baby  
B. Third stage of labour for controlled cord traction to deliver the placenta  
C. First stage for cervical ripening  
D. Fourth stage for uterine massage  

**Answer: B. Third stage of labour for controlled cord traction to deliver the placenta**  
**Explanation:** The Brandt-Andrews method involves: (1) one hand applies counter-traction (suprapubic pressure to stabilise the uterus and prevent inversion), while (2) the other hand applies steady, controlled downward and outward traction on the clamped umbilical cord after a sign of placental separation. It is performed only after uterotonic administration and signs of separation.

**Q49. Which assessment finding indicates that the mother is progressing normally through the active phase of labour?**

A. Cervical dilation of 1 cm or more per hour  
B. Cervical dilation of 0.5 cm per hour  
C. No change in station over 2 hours  
D. Contractions decreasing in frequency  

**Answer: A. Cervical dilation of 1 cm or more per hour**  
**Explanation:** Normal progress in the active phase of labour (from approximately 6 cm to complete dilation) is at least 1 cm per hour in nulliparous women and 1.2–1.5 cm per hour in multiparous women. Failure to progress (arrest of dilation) is diagnosed when there is no cervical change over 4 hours with adequate contractions, or 6 hours with inadequate contractions.

**Q50. A nurse observes meconium-stained amniotic fluid at the time of rupture of membranes. The CORRECT nursing response is:**

A. Immediate cesarean section  
B. Notify the physician, increase fetal monitoring, and ensure neonatal resuscitation team is present at delivery  
C. Administer antibiotics immediately  
D. Perform amnioinfusion without physician order  

**Answer: B. Notify the physician, increase fetal monitoring, and ensure neonatal resuscitation team is present at delivery**  
**Explanation:** Meconium-stained amniotic fluid can indicate fetal distress (hypoxia causing vagal stimulation leading to meconium passage) and carries the risk of meconium aspiration syndrome (MAS) in the neonate. Nursing actions include: notifying the physician immediately, intensifying fetal heart rate monitoring, preparing for possible amnioinfusion if ordered, and ensuring that skilled neonatal personnel capable of endotracheal intubation are present at delivery.
