Labor and Delivery Practice Questions

Q: The normal rate of dilatation of the cervix in a primigravida in the active phase of labor is

1 cm/hour. ***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.

Q: Match List-I with List-II and select the correct answer using the code given below the Lists:

A→2 B→3 C→1 D→4. ***A→2 B→3 C→1 D→4*** - **Hand prolapse (A)** occurs when a fetal hand prolapses alongside the presenting part, leading to obstructed labor. If the fetus is dead and vaginal delivery is impossible due to severe obstruction, **Decapitation (2)** may be performed as a destructive procedure to facilitate delivery. - **Placental delivery (B)** is managed by the **Brandt-Andrews maneuver (3)**, which involves controlled cord traction with counter-pressure on the uterus to prevent uterine inversion and facilitate safe placental separation. - **Extended arms of breech at delivery (C)** occurs when the fetal arms are extended above the head during breech presentation. The **Lovset maneuver (1)** is specifically designed to deliver extended arms by rotating the fetus to bring the posterior arm down and anteriorly. - **Deep transverse arrest (D)** occurs when the fetal head arrests in the transverse diameter of the pelvis. **Forceps delivery or vacuum extraction (4)** can be used with manual or instrumental rotation to deliver the fetal head. *A→4 B→1 C→3 D→2* - This incorrectly matches hand prolapse with vacuum extraction, which cannot address the obstruction caused by a prolapsed hand. It also reverses the Brandt-Andrews maneuver and Lovset technique. *A→2 B→1 C→3 D→4* - This incorrectly matches placental delivery with Lovset technique (which is for breech) and extended arms with Brandt-Andrews maneuver (which is for placental delivery). *A→4 B→3 C→1 D→2* - This incorrectly matches hand prolapse with vacuum extraction and deep transverse arrest with decapitation. Decapitation is not indicated for deep transverse arrest, which can be managed with forceps or vacuum.

Q: A patient who just delivered at home presents with a third degree perineal tear. You will do the repair:

immediately. ***immediately*** - Repair of a **third-degree perineal tear** should be done **immediately** after diagnosis to minimize complications like infection, pain, and long-term functional issues. - Prompt repair helps to restore **anatomical integrity** and improve outcomes for continence and discomfort. *after 24 hours.* - Delaying the repair by 24 hours increases the risk of **infection**, **edema**, and further tissue damage, making the repair more difficult and less successful. - This delay could also lead to increased **blood loss** and patient discomfort. *after 6 weeks* - Waiting 6 weeks would allow for scar tissue formation and potential infection, making a primary repair much more challenging and possibly requiring a more complex secondary repair. - This delay would significantly increase the risk of **fecal incontinence** and other long-term complications. *after 3 months* - A three-month delay is inappropriate for a fresh perineal tear as it guarantees significant **scarring**, **fibrosis**, and high risk of **infection**. - By this time, the tear would likely have healed by secondary intention, resulting in poor anatomical and functional outcomes, often necessitating a more complicated and less effective **secondary repair**.

Q: Face to pubes delivery occurs in which of the foetal position?

Occipito-sacral. ***Occipito-sacral (Occipito-posterior)*** - **"Face to pubes" delivery** is the classic mechanism in **persistent occipito-posterior (OP)** positions where the occiput is directed toward the maternal sacrum. - In this position, the fetal head delivers with **maximum extension**, and the **face passes under the pubic symphysis** (hence "face to pubes"). - The occiput sweeps over the perineum posteriorly, leading to increased perineal trauma and potential for third/fourth-degree tears. - This delivery mechanism is associated with **prolonged labor, increased back pain**, and higher rates of operative delivery. *Mentoanterior* - In **mentoanterior (MA)** face presentation, the fetal chin is anterior, and delivery occurs by **flexion after the chin passes under the symphysis**. - The mechanism involves the chin sweeping the perineum, NOT "face to pubes" delivery. - While mentoanterior can deliver vaginally, the delivery mechanism is distinctly different from occipito-posterior positions. *Brow presentation* - In **brow presentation**, the head is partially extended with the **frontal bone and anterior fontanelle presenting**. - This presents the **largest diameter (mento-vertical ~13.5 cm)** to the pelvis, making vaginal delivery virtually impossible. - Almost always requires **cesarean section** for safe delivery. *Mentoposterior* - In **mentoposterior (MP)** face presentation, the fetal chin is directed posteriorly toward the maternal sacrum. - This position **cannot deliver vaginally** as further extension of the already extended head is impossible. - Requires **rotation to mentoanterior** or cesarean section for delivery.

Q: A G 2 P 1 A 0 presents with full term pregnancy with transverse lie in the first stage of labour. On examination, cervix is 5 cm dilated, membranes are intact and foetal heart sounds are regular. The appropriate management would be:

Caesarean section. ***Caesarean section*** - A **transverse lie** at term in the first stage of labor is a contraindication to vaginal delivery due to the high risk of **cord prolapse**, **uterine rupture**, and fetal distress. - **Caesarean section** is the safest mode of delivery for both mother and fetus in this scenario, as it prevents these complications. *External cephalic version* - **External cephalic version** is typically attempted in cases of **breech presentation** in the late third trimester (around 36-37 weeks) to convert it to a cephalic presentation. - It is **contraindicated** in transverse lie during active labor, especially with cervical dilation, as it has a low success rate and can lead to complications such as **placental abruption** or **cord prolapse**. *Internal podalic version* - **Internal podalic version** is a procedure typically reserved for the delivery of the second twin in a **transverse or oblique lie**, or in some cases of breech presentation. - It carries significant risks, including **uterine rupture** and fetal injury, and is generally not performed for a singleton pregnancy with cervical dilation. *Wait for spontaneous evolution and expulsion* - **Spontaneous evolution** (where the fetus rotates to a longitudinal lie) is extremely rare in a transverse lie presentation at term, especially once labor has started. - Waiting for spontaneous rotation would lead to **prolonged labor**, increased risk of **uterine rupture**, and severe fetal compromise due to obstruction.

Q: Which one of the following is not a complication of shoulder dystocia?

Placental abruption. ***Placental abruption*** - **Placental abruption** is the premature detachment of the placenta from the uterine wall, typically occurring before or during labour. It is not directly caused by the mechanical obstruction during shoulder dystocia. - Complications of shoulder dystocia are primarily related to mechanical forces exerted on the baby and mother during delivery, such as nerve injuries or uterine atony, not placental conditions. *Brachial plexus palsy* - **Brachial plexus palsy** is a common complication of shoulder dystocia, often resulting from excessive lateral traction on the fetal head or neck during delivery. - This traction can stretch or tear the nerves of the brachial plexus, leading to varying degrees of paralysis or weakness in the arm and hand. *Postpartum haemorrhage* - **Postpartum haemorrhage** is a significant risk following shoulder dystocia due to the prolonged and often traumatic nature of the delivery. - The increased manipulation and potential for uterine atony or soft tissue trauma during resolution of shoulder dystocia can predispose the mother to excessive bleeding. *Facial palsy* - **Facial palsy** can occur during shoulder dystocia if there is compression or stretching of the facial nerve (cranial nerve VII) against the maternal pelvis or other structures during delivery. - While less common than brachial plexus palsy, it can result from the abnormal forces and positions during a difficult shoulder dystocia delivery.

Q: Immediately after third stage of labour in a case of full term delivery, the fundus of the uterus is:

At the level of umbilicus. ***At the level of umbilicus*** - Immediately after delivery of the placenta (third stage of labor), the **fundus** typically contracts down to the level of the **umbilicus**. - This contraction helps to compress uterine blood vessels and prevent **postpartum hemorrhage**. *At the level of xiphisternum* - The uterus reaches the **xiphisternum** only in late third trimester, as the fetus grows. - After delivery, the uterus significantly reduces in size, so it would not remain this high. *Below the level of umbilicus* - While the uterus will eventually descend below the umbilicus during **involution** (shrinking back to pre-pregnancy size), this process takes several days to weeks, not immediately after delivery. - A fundus below the umbilicus immediately after delivery might suggest a failure of proper contraction. *Just above the symphysis pubis* - The uterus is at the level of the **symphysis pubis** much earlier in pregnancy, typically around **12 weeks gestation**. - A fundus at this level immediately after delivery would indicate an abnormally small uterus or an incomplete emptying.

Q: Which one of the following is not a suitable condition for outlet forceps application?

Head is above ischial spine level. ***Head is above ischial spine level*** - For **outlet forceps** application, the fetal head must be engaged, meaning the **leading point of the skull** is at or below the **level of the ischial spines (+2 station or lower)**. - If the head is above the ischial spines, it indicates a higher station, making **outlet forceps** an inappropriate and potentially dangerous choice, as it could lead to fetal or maternal injury. *Cervix fully dilated* - This is a **prerequisite** for any type of **forceps delivery**, including outlet forceps. - Performing forceps delivery with a partially dilated cervix risks severe **cervical lacerations** and other maternal complications. *Membranes absent* - This condition refers to **ruptured membranes**, which is a **necessary condition** for safe forceps application. - Intact membranes would prevent proper application of the forceps blades to the fetal head and increase the risk of **fetal scalp injury**. *Vertex presentation* - **Outlet forceps** are primarily used for **vertex presentations** (head-first), where the fetal head is oriented optimally for delivery. - Other presentations, such as **breech** or **transverse**, are **contraindications** for outlet forceps and typically require **cesarean section** or other delivery methods.
