Stages of Labor and Normal Progression Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Stages of Labor and Normal Progression. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Stages of Labor and Normal Progression Indian Medical PG Question 1: What is true about the partograph?
- A. Alert and action lines are separated by a difference of 4 hours in a standard partograph. (Correct Answer)
- B. Partograph recording should be started at a cervical dilation of 4 cm.
- C. Each small square represents 30 minutes.
- D. Send the patient to the first referral unit if the labor progression line crosses the action line.
Stages of Labor and Normal Progression Explanation: ***Alert and action lines are separated by a difference of 4 hours in a standard partograph.***
- This is **CORRECT**. In the WHO partograph, the **alert line** and **action line** are separated by **4 hours**.
- The alert line runs parallel to the expected labor progression, while the action line is 4 hours to the right.
- This 4-hour interval allows for close monitoring and timely intervention if labor progress deviates from normal.
*Partograph recording should be started at a cervical dilation of 4 cm.*
- According to **WHO 2018 guidelines**, partograph recording should now be started at **5 cm dilation**, marking the active phase of first stage of labor.
- The older recommendation of 4 cm is outdated, though it may still appear in some textbooks.
- Starting at 5 cm better defines the active phase and reduces unnecessary interventions.
*Each small square represents 30 minutes.*
- In a standard WHO partograph, each small square on the time axis represents **1 hour**, not 30 minutes.
- This allows for hourly recording of cervical dilation, fetal heart rate, contractions, and other labor parameters.
*Send the patient to the first referral unit if the labor progression line crosses the action line.*
- When the labor curve crosses the **action line**, it indicates **prolonged labor** requiring immediate intervention.
- The appropriate action depends on facility capabilities: this may include **augmentation of labor, preparing for cesarean section**, or referral if necessary.
- Automatic referral is not the only or primary response; active management at the current facility is often appropriate.
Stages of Labor and Normal Progression Indian Medical PG Question 2: Which of the following is consistent with a decision to perform a cerclage?
- A. Gestation of 26 weeks
- B. Uterine bleeding
- C. Uterine contractions
- D. Cervix dilated to 3 cm (Correct Answer)
Stages of Labor and Normal Progression Explanation: ***Cervix dilated to 3 cm***
- In the context of **mid-trimester cervical dilation** (before 24 weeks) without contractions or bleeding, this represents **cervical insufficiency** - a potential indication for **emergency (rescue) cerclage**.
- While 3 cm dilation is at the **upper limit** and somewhat controversial, emergency cerclage may still be considered if membranes are intact, there are no contractions, and gestational age is <24 weeks.
- This is the **only option** that represents a clinical scenario where cerclage might be performed, as the other three options are **absolute contraindications**.
- Note: Most clinicians prefer cervical dilation **<2 cm** for rescue cerclage, but individual cases at 2-3 cm may be considered based on clinical judgment.
*Gestation of 26 weeks*
- Cerclage is typically placed between **12-14 weeks** (prophylactic) or up to **23-24 weeks** (emergency).
- At **26 weeks**, cerclage is **contraindicated** - the risks (membrane rupture, infection, preterm labor) outweigh benefits at this advanced gestation.
- This is an **absolute contraindication** regardless of cervical findings.
*Uterine bleeding*
- **Active uterine bleeding** is an **absolute contraindication** to cerclage placement.
- Bleeding increases risks of **infection, membrane rupture, and preterm labor**.
- Must rule out **placental abruption, placenta previa**, or other complications before considering any cervical intervention.
*Uterine contractions*
- **Active uterine contractions** are an **absolute contraindication** for cerclage.
- Placing cerclage during contractions can precipitate **preterm labor and delivery**.
- Contractions indicate the cervix may be responding to labor stimuli, making cerclage ineffective and potentially harmful.
Stages of Labor and Normal Progression Indian Medical PG Question 3: A primigravida presents to the labor room at 40 weeks of gestation with lower abdominal pain. She has been in labor for 3 hours. Which of the following will determine if she is in active labor?
- A. Fetal head 5/5 palpable on abdominal examination
- B. Two contractions lasting for 10 seconds in 10 minutes
- C. Rupture of membranes
- D. Cervical dilatation of 6 cm or more with regular contractions (Correct Answer)
Stages of Labor and Normal Progression Explanation: ***Cervical dilatation of 6 cm or more with regular contractions***
- Active labor is officially defined by **cervical dilatation of 6 cm or more** according to the ACOG and SMFM 2014 consensus guidelines, which redefined the labor curve based on the Consortium on Safe Labor study.
- This represents a shift from the traditional Friedman curve definition of 4 cm, recognizing that **significant progressive cervical change** with regular uterine contractions is the hallmark of active labor.
- Complete effacement typically occurs during the latent phase, and while regular contractions accompany active labor, **cervical dilatation ≥6 cm is the primary diagnostic criterion**.
*Fetal head 5/5 palpable on abdominal examination*
- This finding indicates a **high fetal head** that is not engaged (0/5 of the head has entered the pelvis), which does not determine whether active labor has begun.
- **Fetal station and engagement** are important for assessing labor progression and potential for cephalopelvic disproportion, but are not the primary criteria for diagnosing active labor.
*Two contractions lasting for 10 seconds in 10 minutes*
- These contractions are **infrequent and very short**, more characteristic of latent labor or Braxton Hicks contractions.
- Active labor typically involves **3-5 contractions in 10 minutes, each lasting 45-60 seconds**, with sufficient intensity to cause progressive cervical change.
*Rupture of membranes*
- **Rupture of membranes (ROM)**, whether spontaneous or artificial, is an important event but does not by itself indicate active labor.
- A woman can have ROM in the **latent phase** or even before labor begins (prelabor ROM or PROM), and **cervical dilatation remains the primary determinant** of active labor.
Stages of Labor and Normal Progression Indian Medical PG Question 4: A multigravida at term with a transverse lie and hand prolapse, along with a fetal heart rate of 140/min, is best managed by:
- A. External cephalic version
- B. Cesarean delivery (Correct Answer)
- C. Breech delivery
- D. Internal podalic version
Stages of Labor and Normal Progression Explanation: ***Cesarean delivery***
- A **transverse lie** at term is a contraindication to vaginal delivery, as the fetus cannot pass through the birth canal in this orientation.
- The presence of **hand prolapse** further complicates the situation, increasing the risk of umbilical cord prolapse and fetal distress, making cesarean section the safest option.
*External cephalic version*
- This procedure is performed to change a **breech or transverse lie** to a cephalic presentation, but it is typically done *before* term, usually between 36-37 weeks.
- It is contraindicated once labor has started or with **membrane rupture** and fetal parts prolapsed, as is implied by hand prolapse in this term patient.
*Breech delivery*
- Breech delivery involves the fetus presenting buttocks or feet first, which is not the case here; the presentation is **transverse lie** and **hand prolapse**.
- While some breech deliveries can be attempted vaginally under specific circumstances, this patient's presentation makes it an inappropriate option.
*Internal podalic version*
- This procedure involves changing a **transverse lie** to a **breech presentation** by internal manipulation, often performed in cases of twin delivery for the second twin or in specific scenarios of malpresentation in earlier gestations.
- It is rarely performed for a single fetus at term due to risks for both mother and fetus, especially with a **term fetus** and **hand prolapse**.
Stages of Labor and Normal Progression Indian Medical PG Question 5: Female with 41 wk gestation confirmed by radiological investigation, very sure of her LMP, no uterine contractions, no effacement and no dilatation. What should be done to induce labor?
- A. PGE1 tab (Correct Answer)
- B. PGE2 gel
- C. PGF2alpha
- D. Intracervical foley’s
Stages of Labor and Normal Progression Explanation: ***PGE1 tab***
- **Misoprostol (PGE1)** is an effective agent for **cervical ripening** and labor induction in cases of an unfavorable cervix (no effacement, no dilatation).
- It is cost-effective, stable at room temperature, and widely used in resource-limited settings.
- Can be administered orally or vaginally with good efficacy for cervical ripening at term.
- In this post-term pregnancy with unfavorable cervix, pharmacological ripening is appropriate.
*PGE2 gel*
- **PGE2 (dinoprostone)** gel or cervical insert is also an effective option for cervical ripening.
- Both PGE1 and PGE2 are acceptable first-line agents; the choice may depend on availability, cost, and institutional protocols.
- PGE2 formulations are FDA-approved and widely used, though may be more expensive than misoprostol.
*PGF2alpha*
- **PGF2alpha (carboprost)** is primarily used for the **management of postpartum hemorrhage** due to its potent myometrial contracting effect.
- It is **not indicated** for induction of labor at term as its strong uterine contractions can cause excessive uterine stimulation and fetal distress.
*Intracervical foley's*
- An **intracervical Foley catheter** is a mechanical method that causes cervical ripening through direct pressure and stimulation of local prostaglandin release.
- It is an evidence-based alternative with lower risk of uterine hyperstimulation compared to pharmacological methods.
- Both mechanical and pharmacological methods are acceptable first-line options for cervical ripening in post-term pregnancy with unfavorable cervix.
Stages of Labor and Normal Progression Indian Medical PG Question 6: A pregnant female presents with active herpetic lesions on the vulva. What is the most appropriate management?
- A. Wait & watch
- B. Acyclovir & elective cesarean section (C-section) (Correct Answer)
- C. Acyclovir & allow spontaneous progression of labor
- D. Induction of labor
Stages of Labor and Normal Progression Explanation: ***Acyclovir & elective cesarean section (C-section)***
- Active **genital herpetic lesions** at the time of delivery pose a significant risk of transmitting **herpes simplex virus (HSV)** to the neonate.
- **Acyclovir** can help suppress viral replication, but a **cesarean section** is necessary to prevent direct contact with the lesions during birth, which could lead to severe neonatal HSV infection.
*Wait & watch*
- This approach is inappropriate due to the high risk of **vertical transmission** of HSV to the neonate if lesions are active during vaginal delivery, potentially causing life-threatening complications.
- **Neonatal HSV** can result in significant morbidity and mortality, including neurological damage and disseminated disease.
*Acyclovir & allow spontaneous progression of labor*
- While **acyclovir** can reduce viral load, it does not completely eliminate the risk of transmission from active lesions during a vaginal birth.
- The primary concern is protecting the neonate from direct contact with the **active lesions** in the birth canal.
*Induction of labor*
- **Induction of labor** does not mitigate the risk of **vertical transmission** from active lesions during a vaginal delivery.
- The focus should be on preventing contact with the lesions, not on expediting vaginal birth once active lesions are present.
Stages of Labor and Normal Progression Indian Medical PG Question 7: The normal rate of dilatation of the cervix in a primigravida in the active phase of labor is
- A. 1 cm/hour (Correct Answer)
- B. 0.25 cm/hour
- C. 0.75 cm/hour
- D. 0.5 cm/hour
Stages of Labor and Normal Progression Explanation: ***1 cm/hour***
- The **active phase** of labor in a **primigravida** (first-time mother) is characterized by a cervical dilatation rate of at least 1 cm per hour.
- This rate signifies good progress and is often used as a benchmark on a **partogram** to monitor labor.
*0.25 cm/hour*
- This rate is significantly **slower** than normal for the active phase of labor in a primigravida and would indicate **abnormal labor progression**, possibly requiring intervention.
- Such a slow rate might be seen in the **latent phase** or in cases of **protracted labor**.
*0.75 cm/hour*
- While closer, this rate is still **below the expected minimum** for a primigravida in the active phase, suggesting slightly slower than optimal progress.
- It could still indicate a **protracted active phase**, particularly if it persists.
*0.5 cm/hour*
- This rate is **substantially slower** than the typical progress in the active phase of labor for a primigravida.
- It would be a strong indicator of **failure to progress** and would likely warrant a thorough evaluation for potential causes such as **cephalopelvic disproportion** or ineffective uterine contractions.
Stages of Labor and Normal Progression Indian Medical PG Question 8: The Matthews Duncan process has been described for :
- A. controlled contraction in active management of third stage of labour
- B. central separation of placenta in normal labour
- C. marginal separation of placenta in normal labour (Correct Answer)
- D. reposition of acute inversion of uterus following vaginal delivery
Stages of Labor and Normal Progression Explanation: ***Marginal separation of placenta in normal labour***
- The **Matthews Duncan method** describes the process of **placental separation** where the placenta detaches from its **edges first**, leading to bleeding from the exposed maternal surface.
- This type of separation is one of the two main mechanisms by which the placenta separates from the **uterine wall** during the third stage of labor.
*Controlled contraction in active management of third stage of labour*
- This refers to techniques like **controlled cord traction** and **fundal massage**, which are part of the active management to expedite placental delivery and prevent hemorrhage.
- While it's a part of third stage management, it describes an intervention for placental expulsion, not a specific mechanism of placental detachment.
*Central separation of placenta in normal labour*
- This is known as the **Schultze method**, where placental separation begins in the **center**, leading to the fetal surface presenting first and less visible bleeding during separation.
- The question specifically asks about the **Matthews Duncan process**, which is distinct from central separation.
*Reposition of acute inversion of uterus following vaginal delivery*
- **Uterine inversion** is a rare but severe complication where the **fundus** collapses through the **cervix**.
- Repositioning involves manual or surgical techniques to return the uterus to its normal anatomical position and is unrelated to placental separation mechanisms.
Stages of Labor and Normal Progression Indian Medical PG Question 9: According to WHO Intrapartum Care Guidelines 2018, which one of the following is correct about duration of first stage labour?
- A. Duration of active stage of primigravida should not exceed 8 hours
- B. Duration of active stage of multigravida should not exceed 6 hours
- C. Duration of active stage of primigravida should not exceed 18 hours
- D. Duration of latent phase of primigravida has not been established (Correct Answer)
Stages of Labor and Normal Progression Explanation: ***Duration of latent phase of primigravida has not been established***
- The **WHO Intrapartum Care Guidelines 2018** state that for both primigravid and multiparous women, the duration of the **latent phase of labor** has significant variability and a specific maximum duration to define prolonged labor has not been established.
- This reflects the understanding that the latent phase can be variable and does not necessarily require intervention if the woman and fetus are well.
*Duration of active stage of primigravida should not exceed 8 hours*
- The 2018 WHO guidelines suggest that the **active phase of first-stage labor** for a **primigravida** can be up to **12 hours** or even longer, as long as there is continuous progress in cervical dilation.
- The concept of a rigid 8-hour limit for all primigravidae in the active phase is not supported by current evidence-based guidelines, which emphasize individual progress.
*Duration of active stage of multigravida should not exceed 6 hours*
- For **multigravid women**, the active phase of the first stage of labor is generally shorter than for primigravidae, but the WHO guidelines do not set a strict upper limit of 6 hours.
- Instead, they emphasize that progress in cervical dilation should be monitored, and interventions should be based on a lack of progress along with other clinical indicators, rather than a fixed time frame.
*Duration of active stage of primigravida should not exceed 18 hours*
- While the active phase of labor can be prolonged, a "should not exceed 18 hours" limit is not explicitly defined in the way it is presented.
- The **WHO guidelines** advocate for continuous monitoring of cervical dilation, with an expected rate of at least 1 cm/hour during the active phase, acknowledging that some women may have slower but still physiological progress.
Stages of Labor and Normal Progression Indian Medical PG Question 10: Which of the following is a part of AMTSL?
- A. Uterine massage
- B. Controlled cord traction (Correct Answer)
- C. Early cord clamping
- D. Uterotonics after delivery of placenta
Stages of Labor and Normal Progression Explanation: ***Controlled cord traction***
- **Controlled cord traction (CCT)** is a key component of Active Management of Third Stage of Labor (AMTSL) performed during placental delivery.
- This technique involves applying gentle, sustained traction to the umbilical cord while simultaneously providing counter-traction to the fundus (Brandt-Andrews maneuver) to prevent **uterine inversion**.
- CCT is performed after administering a uterotonic and is the primary active maneuver for delivering the placenta.
*Uterine massage*
- **Uterine massage** is also a component of AMTSL, but it is performed **after placental delivery** to ensure adequate uterine contraction and prevent postpartum hemorrhage.
- The three components of AMTSL per WHO recommendations are: (1) Uterotonic administration, (2) Controlled cord traction, (3) Uterine massage after placental delivery.
- While technically part of AMTSL, **controlled cord traction** is the more specific answer as it refers to the active maneuver during placental separation and delivery itself.
*Early cord clamping*
- **Early cord clamping** (within 60 seconds of birth) has been removed from AMTSL recommendations in favor of **delayed cord clamping** (1-3 minutes or when pulsation stops).
- Current WHO guidelines recommend delayed cord clamping for all births while still performing AMTSL, as delayed clamping provides neonatal benefits without increasing maternal hemorrhage risk.
*Uterotonics after delivery of placenta*
- **Uterotonics** (oxytocin 10 IU IM/IV) are administered **within 1 minute of birth** of the baby, which is *before* placental delivery, not after.
- This prophylactic administration is the cornerstone of AMTSL and reduces postpartum hemorrhage risk by approximately 60%.
- Administering uterotonics *after* placental delivery does not constitute proper AMTSL timing.
