Labor and Delivery Practice Questions

Q: The components of partograph are all EXCEPT:

Maternal respiratory rate. ***Maternal respiratory rate*** - While important for overall maternal well-being, **maternal respiratory rate** is not a standard component recorded on a partograph. - The partograph primarily focuses on monitoring fetal well-being, cervical dilation, and uterine contractions to track labor progress. *Fetal heart rate* - **Fetal heart rate** is a crucial component of the partograph, regularly plotted to assess fetal well-being and identify signs of distress. - It helps in detecting fetal hypoxia and guiding interventions if necessary during labor. *Time* - **Time** is a fundamental axis on the partograph, allowing for the plotting of all other parameters against a temporal scale. - This enables the healthcare provider to visualize the progression of labor and identify deviations from normal patterns. *Maternal urine analysis* - **Maternal urine analysis** for protein, acetone, or glucose is a standard component of the partograph. - It helps in assessing maternal hydration status and detecting potential complications like pre-eclampsia or gestational diabetes that might impact labor or fetal health.

Q: Which one of the following is NOT a component of active phase in the partograph?

Phase of expulsion. ***Phase of expulsion*** - The **phase of expulsion** (or the second stage of labor) begins after the cervix is fully dilated and ends with the birth of the baby. - While it immediately follows the active phase, it is not considered a component of the **active phase** itself, which primarily focuses on cervical dilation progress. *Acceleration phase* - The **acceleration phase** is an early part of the active phase of labor where the rate of cervical dilation begins to increase. - It marks the transition from the latent phase to the more rapid dilation characteristic of active labor. *Phase of deceleration* - The **phase of deceleration** occurs towards the end of the active phase, just before full cervical dilation, where the rate of dilation slows down. - This phase is typically associated with the advancing fetal head encountering the pelvic floor. *Phase of maximum slope* - The **phase of maximum slope** (or maximum ascent) is the steepest part of the active phase, where cervical dilation occurs at its fastest rate. - This is the most efficient period of cervical change during labor.

Q: Successful external cephalic version of breech presentation is likely in case all of the following EXCEPT:

Breech with extended legs. ***Breech with extended legs*** - An extended leg presentation (frank breech) makes successful external cephalic version **less likely** because the **fetal legs splint the fetus**, creating a rigid, elongated configuration that resists rotation. - The extended posture restricts fetal mobility necessary for successful manipulation. - Frank breech is the **least favorable type** for ECV success. *Non engaged breech* - A **non-engaged breech** presentation indicates the fetal buttocks or feet are not yet fixed in the maternal pelvis, allowing **greater mobility** and making successful external cephalic version **more likely**. - Lack of engagement means there is ample space for the fetus to turn. *Adequate amniotic fluid* - **Adequate amniotic fluid** provides essential space and cushioning for the fetus to move, which is crucial for a successful external cephalic version. - It reduces friction and allows for easier manipulation of the fetus during the procedure. - Oligohydramnios is a relative contraindication to ECV. *Complete breech with sacroanterior position* - A **complete breech** (with flexed hips and knees) is generally **more favorable** for external cephalic version compared to frank breech, as the flexed posture creates a more compact, mobile configuration. - The fetal position (sacroanterior, sacrotransverse, or sacroposterior) has less impact on ECV success than the **type of breech presentation** (complete vs. frank). - Complete breech allows easier manipulation than the rigid frank breech configuration.

Q: Which one of the following is NOT a method of management of Deep Transverse Arrest with the living fetus?

Delivery by ventouse. ***Delivery by ventouse*** - **Vacuum extraction (ventouse)** requires the fetal head to be engaged and the leading part to be no higher than 1/5th above the symphysis pubis, and it does not allow for rotation once applied. - In a **deep transverse arrest**, the fetal head is unrotated, and direct application of a ventouse without prior rotation is unsafe and ineffective, as it would apply traction in an improper direction, risking scalp injury without resolving the arrest. *Caesarean section* - **Caesarean section** is a viable and often necessary option for deep transverse arrest, especially when other rotational or instrumental delivery methods are contraindicated or unsuccessful. - It ensures safe delivery for both mother and fetus in cases of **cephalopelvic disproportion** or failed operative vaginal delivery. *Manual rotation and application of forceps* - **Manual rotation** involves an obstetrician manually turning the fetal head from the transverse to the occipito-anterior or posterior position. - After successful manual rotation, **forceps** can then be applied to facilitate vaginal delivery, provided there are no other contraindications. *Delivery by application of forceps to the unrotated head* - **Kielland's forceps** are specifically designed for rotation and delivery in cases of **deep transverse arrest** and can be applied to an unrotated head to achieve rotation without prior manual intervention. - While other types of forceps typically require the head to be in an occipito-anterior position, Kielland's forceps allow for the necessary rotation before traction is applied, making it a suitable method for managing deep transverse arrest.

Q: Based on the educational diagram showing different degrees of perineal tears, which degree involves only the perineal skin and vaginal mucosa without affecting the underlying muscle?

1st degree. ***1st degree*** - Involves only the **perineal skin** and **vaginal mucosa** without affecting underlying muscle tissue. - The **pelvic floor muscles (PFM)** remain completely intact, making this the most superficial type of perineal tear. *2nd degree* - Extends deeper to involve the **perineal muscles** including the pelvic floor muscles, but spares the anal sphincter. - Requires **muscle repair** in addition to skin closure, making it more complex than 1st degree tears. *3rd degree* - Involves the **anal sphincter complex** (external and/or internal anal sphincter) extending toward the anus. - Requires specialized **sphincter reconstruction** to prevent future fecal incontinence complications. *4th degree* - The most severe tear extending through the **anal sphincter** and into the **rectal mucosa**. - Requires **multilayer repair** including rectal mucosa, sphincter complex, and perineal tissues to restore anatomy.

Q: What is the method of delivery for fetuses $A$ and $B$ as shown in the image

LSCS in both. ***LSCS in both*** - Fetus A is in a **breech presentation**, which is an indication for cesarean section in twin pregnancy, especially when it is the first (presenting) twin. - Once the decision is made to perform a **cesarean section (LSCS)** for fetus A, **both twins must be delivered through the same cesarean incision** during the same operative procedure. - It is **not possible or safe** to deliver one twin by cesarean section and then attempt vaginal delivery for the second twin. Once the uterine incision is made, both babies are delivered through that incision. - This is the standard obstetric practice for twin deliveries requiring cesarean section. *LSCS, vaginal* - This option is **medically incorrect** and represents a misunderstanding of cesarean delivery principles. - Once a cesarean section is initiated for twin A, **both twins are delivered through the uterine incision** during the same surgery. - There is no scenario where one twin is delivered by cesarean and the other vaginally in the same delivery episode - this would be unsafe and is not practiced. *Vaginal, LSCS* - This is incorrect because fetus A (the presenting/first twin) is in **breech presentation**, which typically contraindicates vaginal delivery as the first twin. - In twin pregnancies, when the first twin is breech, **cesarean section is generally recommended** to avoid complications such as head entrapment or cord prolapse. - The mode of delivery for the first twin determines the approach, and a breech first twin usually necessitates cesarean delivery for both. *Induce delivery in both* - Induction of labor aims to initiate contractions but does not address the **breech presentation of fetus A**. - With fetus A in breech presentation, induction would still lead to the need for cesarean section due to the unfavorable presentation of the first twin. - Induction is not an appropriate management strategy when the presenting twin is breech in twin pregnancy.

Q: Which of the following is not a contraindication for External Cephalic Version (ECV)?

Primigravida. ***Primigravida*** - Being a **primigravida** (first pregnancy) is not a contraindication for ECV, though it might be associated with a slightly lower success rate compared to multiparous women due to a less pliable uterus. - While it may indicate a potentially more challenging ECV due to higher uterine tone, it does not preclude the procedure if other conditions are favorable. *Placenta previa* - **Placenta previa** is a contraindication because the manipulation of the uterus during ECV could dislodge the placenta, leading to **severe hemorrhage** and potential fetal compromise. - This condition involves the placenta covering the cervical opening, making any uterine intervention risky. *Twin pregnancy* - **Twin pregnancy** is a contraindication as ECV is generally not recommended in multiple gestations due to increased complexity and risk of complications. - The risk of **umbilical cord entanglement**, disruption of twin positioning, and potential harm to either fetus makes ECV unsafe in twin pregnancies. *PROM (Premature Rupture of Membranes)* - **Premature Rupture of Membranes (PROM)** is a contraindication due to the increased risk of uterine infection and **cord prolapse** during manipulation. - Once membranes are ruptured, the natural cushioning provided by the amniotic fluid is lost, making ECV potentially traumatic for both the mother and the fetus.

Q: In the image showing twin pregnancy where fetus A (first twin) is in breech presentation and fetus B (second twin) is in cephalic presentation, what is the recommended method of delivery for fetuses A and B respectively?

LSCS in both. ***LSCS in both*** - When the **first twin (Twin A) is in breech presentation**, current guidelines recommend **cesarean section (LSCS) for BOTH twins** - This avoids significant risks including **head entrapment**, **umbilical cord prolapse**, and **birth trauma** associated with vaginal breech delivery of the first twin - Once a cesarean section is performed for Twin A, delivering Twin B through the same uterine incision is **safer and standard practice** rather than attempting vaginal delivery - **ACOG guidelines** and the **Twin Birth Study (2013)** support cesarean delivery for both twins when Twin A is non-cephalic *LSCS, vaginal* - Delivering Twin A by cesarean section and then attempting **vaginal delivery of Twin B is NOT standard practice** and carries unnecessary risks - After opening the uterus for Twin A, delivering Twin B vaginally would leave an **unsutured uterine incision** with risks of hemorrhage and complications - This mixed approach is **not recommended** in modern obstetric practice *Vaginal, LSCS* - Attempting **vaginal breech delivery for Twin A** is associated with significantly higher risks of fetal morbidity and mortality - The sequence described (vaginal then LSCS) is illogical and not practiced clinically *Induce delivery in both* - **Induction of labor** refers to initiating contractions but does not address the **mode of delivery** (vaginal vs cesarean) - The **presentation of Twin A** is the primary determinant of delivery method, and breech presentation of the first twin is an indication for cesarean delivery regardless of induction

Q: A patient presents with infraumbilical flattening and the fetal heart rate is heard laterally. What is the most likely fetal position?

Occipitoposterior. ***Occipitoposterior*** - **Infraumbilical flattening** of the abdomen is a classic sign of an occipitoposterior position due to the fetal spine lying against the maternal spine. - The **heart sounds are heard laterally** because the fetal back, where the heart sounds are best transmitted, is positioned towards the maternal flanks. *Right occipitoanterior* - In a right occipitoanterior position, the fetal spine is anterior and slightly to the right, leading to a more **convex abdomen** and **heart sounds audible anteriorly** and to the right of the midline. - This position does not typically cause infraumbilical flattening. *Right dorsoanterior* - This term is more commonly associated with a **breech presentation** where the fetal back (dorsum) is anterior. - In a cephalic presentation, "dorsoanterior" is not a standard term for fetal position relative to the occiput. *Left occipitoanterior* - In a left occipitoanterior position, the fetal spine is anterior and slightly to the left, resulting in a **convex abdomen** and **heart sounds audible anteriorly** and to the left of the midline. - Infraumbilical flattening is not a characteristic finding for this position.

Q: A pregnant female presents with active herpetic lesions on the vulva. What is the most appropriate management?

Acyclovir & elective cesarean section (C-section). ***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.
