UPSC-CMS 2020 - Obstetrics and Gynecology Practice Questions

Q: As per ICMR guidelines, which one of the following statements is true regarding COVID-19 infection in pregnancy?

Pregnant women with heart disease are at higher risk. ***Pregnant women with heart disease are at higher risk*** - Pre-existing **heart disease** is a significant risk factor for severe COVID-19 outcomes in pregnant women due to the increased physiological cardiac demands of both pregnancy and infection. - According to ICMR guidelines and global data, comorbidities like **cardiovascular disease** place pregnant individuals in a higher-risk category for severe illness. *COVID-19 pneumonia in pregnancy is more severe with poor recovery* - While pregnant women *can* develop severe COVID-19 pneumonia, the general consensus, including ICMR guidelines, states that most pregnant women experience **mild to moderate illness** and have a **good recovery**. - Pooled data indicates that the majority of pregnant women with COVID-19 will not develop severe pneumonia or experience poorer recovery *solely* due to pregnancy. *COVID-19 virus is secreted in breast milk* - Current evidence suggests that the **COVID-19 virus is generally not detectable** in breast milk. - ICMR and other major health organizations recommend that **mothers with COVID-19 continue breastfeeding**, as the benefits outweigh potential risks, and antibodies may be transferred. *Vaginal secretions always test positive for COVID-19 in pregnancy* - The primary transmission route for COVID-19 is through **respiratory droplets**, not vaginal secretions. - While some studies have detected viral RNA in vaginal secretions in a small percentage of cases, it is **not always positive** and is not considered a primary source of transmission.

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: 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: Implantation of a fertilised ovum occurs on which day following fertilisation?

Day 6. ***Day 6*** * Fertilization occurs in the **ampulla** of the fallopian tube, and the zygote undergoes cleavage as it travels towards the uterus. * By day 5-6, the embryo develops into a **blastocyst** with an outer trophoblast layer and inner cell mass. * **Implantation begins on day 6-7** post-fertilization when the blastocyst attaches to the endometrium, making day 6 the correct answer for when implantation occurs. * The process continues and is complete by day 10-12, but the initial attachment (implantation) starts on day 6. *Incorrect: Day 14* * Day 14 marks the time of **ovulation** in a typical 28-day menstrual cycle, not implantation. * By day 14 post-fertilization, the embryo would have been implanted for approximately one week. *Incorrect: Day 20* * Implantation occurs much earlier, around day 6-12 post-fertilization. * By day 20 post-fertilization, the implanted embryo would be well into **gastrulation and organogenesis**. *Incorrect: Day 10* * While the implantation process may continue until day 10-12, it **begins on day 6**, not day 10. * Day 10 represents a later stage when implantation is nearly complete, but the question asks when implantation occurs (i.e., begins).

Q: The net effect of antenatal care has been the following EXCEPT:

Reduction in the incidence of institutional delivery. ***Reduction in the incidence of institutional delivery*** - Antenatal care aims to increase awareness of safe delivery practices and encourage women to deliver in health facilities, thereby **increasing institutional deliveries**, not reducing them. - Improved access to and understanding of obstetric care through ANC promotes safer childbirth environments. *Reduction in maternal morbidity* - Antenatal care plays a crucial role in the early detection and management of **pregnancy-related complications** such as pre-eclampsia, gestational diabetes, and infections. - This proactive management minimizes the severity and impact of these conditions on maternal health. *Reduction in perinatal mortality* - Regular antenatal visits allow for monitoring of fetal growth and well-being, identification of **fetal distress**, and intervention for conditions like intrauterine growth restriction. - Early detection and management of issues affecting the fetus significantly improve perinatal outcomes and reduce **stillbirths** and **neonatal deaths**. *Reduction in maternal mortality* - ANC provides essential health education, nutritional advice, and timely vaccinations, which are vital for a healthy pregnancy. - It also facilitates preparedness for childbirth and potential complications, thereby **reducing the risk of maternal death** from preventable causes.

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: 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 of the following information are provided by partograph? 1. Colour of liquor 2. Uterine contractions with duration and frequency 3. Dilatation of cervix Select the correct answer using the code given below:

1, 2 and 3. ***1, 2 and 3*** - A **partograph** is a composite graphical record of key maternal and fetal parameters during labor, specifically designed to monitor the progress of labor and to identify deviations from normal. - It includes charting the **colour of liquor**, **uterine contractions (frequency and duration)**, and **cervical dilatation** to assess the progression of labor. *2 and 3 only* - This option is incorrect because the partograph also records the **colour of liquor** in addition to uterine contractions and cervical dilatation. - The colour of liquor provides vital information about fetal well-being, such as the presence of **meconium**, which indicates fetal distress. *1 and 3 only* - This option is incorrect because the partograph also records the **frequency and duration of uterine contractions**, which are crucial for assessing the power and effectiveness of labor. - Uterine contractions are fundamental to the progress of cervical dilatation and fetal descent. *1 and 2 only* - This option is incorrect because the partograph also records the **dilatation of the cervix**, which is the primary indicator of the progress of the first stage of labor. - The rate of cervical dilatation is crucial for determining if labor is progressing normally or if there is a **protracted labor** requiring intervention.

Q: Hysterosalpingography (HSG) is least helpful in detecting which of the following?

Pelvic adhesions. ***Pelvic adhesions*** - HSG primarily visualizes the uterine cavity and fallopian tubes, making it **poorly suited to detect adhesions outside these structures**. - **Pelvic adhesions** are better evaluated with **laparoscopy**, which allows direct visualization of the abdominal and pelvic organs. *Asherman syndrome* - This condition involves **intrauterine adhesions** which manifest as filling defects or synechiae within the uterine cavity on HSG. - HSG is highly effective in detecting these adhesions and their extent. *Congenital uterine anomaly* - HSG can visualize the shape of the uterine cavity and detect various **congenital anomalies** such as a septate, bicornuate, or arcuate uterus. - The contrast dye fills the uterus, outlining its internal morphology. *Tubal patency* - One of the primary uses of HSG is to assess the **patency of the fallopian tubes** by observing the free spill of contrast into the peritoneal cavity. - Blockages or hydrosalpinges can be clearly identified.

Q: Which of the following are characteristics of Trichomonas vaginitis? 1. Presence of greenish frothy discharge 2. Vaginal pH > 4.5 3. Presence of clue cells in microscopic examination 4. Strawberry spots on the vaginal mucosa Select the correct answer using the code given below:

1, 2 and 4. ***1, 2 and 4*** - **Trichomonas vaginalis** infection classically presents with a **greenish, frothy, malodorous vaginal discharge**, and the vaginal pH is typically **elevated (>4.5)** due to the pathogen's metabolic activity. - The presence of **strawberry spots (colpitis macularis)** on the vaginal and cervical mucosa is a hallmark sign, resulting from punctate hemorrhages. *1, 3 and 4* - This option correctly includes **greenish frothy discharge** and **strawberry spots**, which are characteristic of *Trichomonas vaginitis*. - However, the inclusion of "presence of **clue cells**" is incorrect as clue cells are pathognomonic for **bacterial vaginosis**, not *Trichomonas*. *2, 3 and 4* - This option correctly identifies **vaginal pH > 4.5** and **strawberry spots** as features of *Trichomonas vaginitis*. - The presence of **clue cells** is a misattribution to *Trichomonas* infection; instead, clue cells are defining features of **bacterial vaginosis**. *1, 2 and 3* - While **greenish frothy discharge** and **vaginal pH > 4.5** are indeed characteristic of *Trichomonas vaginitis*, the presence of **clue cells** is a diagnostic criterion for **bacterial vaginosis**. - **Strawberry spots** are a distinct feature of *Trichomonas* that is missing from this selection.
