UPSC-CMS 2020 - Obstetrics and Gynecology PYQs Practice Questions

Q: Which one of the following statements regarding pre-conceptional counseling is NOT correct?

It is needed only in selected complicated pregnancies. ***It is needed only in selected complicated pregnancies*** - Pre-conceptional counseling is important for **all women of reproductive age**, especially those planning a pregnancy, not just for complicated cases. - Its purpose is to **optimize maternal health before conception** to prevent adverse outcomes, regardless of initial perceived risk. *It helps in early detection of risk factors* - Pre-conceptional counseling identifies **maternal and fetal risk factors** such as chronic medical conditions, genetic predisposition, and lifestyle choices before pregnancy. - Early detection allows for ** timely interventions** to mitigate these risks. *It is a part of preventive medicine* - Counseling before pregnancy focuses on **prevention of adverse pregnancy outcomes** by optimizing health and addressing potential issues. - This proactive approach aligns directly with the principles of **preventive healthcare**. *It helps in reducing maternal morbidity and mortality* - By addressing risk factors, optimizing health, and educating women about healthy behaviors, pre-conceptional counseling can significantly **lower the incidence of complications** during pregnancy. - This ultimately contributes to a **reduction in maternal illness and death**.

Q: Consider the following statements regarding Non Stress Test (NST): 1. Reactive NST indicates a healthy fetus 2. NST is an observed association of fetal breathing with fetal movements 3. NST has a low false negative rate ( 50%) 4. Testing should be started at 20 weeks Which of the statement(s) given above is/are correct?

1 and 3. ***1 and 3*** - A **reactive NST** indicates adequate fetal oxygenation and an intact autonomic nervous system, strongly suggesting a **healthy fetus**. - NST has excellent **sensitivity** for detecting fetal well-being, leading to a very **low false-negative rate** (less than 1%), but its relatively high rate of non-reactive results in healthy fetuses contributes to a **high false-positive rate** (over 50%). *1 and 4* - While statement 1 is correct, statement 4 is incorrect because NST testing is typically initiated at **28-32 weeks of gestation**, not 20 weeks, as fetal autonomic nervous system maturation is required. - At 20 weeks, the fetus often lacks the mature neurological responses necessary for a reliable NST. *2 only* - Statement 2 incorrectly describes NST; the NST observes the association of **fetal heart rate accelerations** with **fetal movements**, not fetal breathing. - Fetal breathing movements are typically assessed during a **biophysical profile**, not solely by NST. *3 only* - While statement 3 correctly describes the false negative and positive rates of NST, statement 1 is also correct, as a reactive NST is indeed a strong indicator of a healthy fetus. - This option is incomplete as it misses another correct statement.

Q: Which one of the following is a protective factor for endometrial hyperplasia?

Multiparity. ***Multiparity*** - **Multiparity** is a protective factor against endometrial hyperplasia due to **periods of anovulation and progesterone dominance** during pregnancy. - Each pregnancy provides prolonged exposure to high levels of **progesterone**, which counteracts unopposed estrogenic effects on the endometrium and prevents hyperplasia. - Multiple pregnancies reduce the total number of **ovulatory cycles** in a woman's lifetime, thereby decreasing cumulative exposure to unopposed estrogen. *Tamoxifen therapy* - **Tamoxifen**, while an anti-estrogen in breast tissue, acts as a **partial estrogen agonist** on the endometrium, increasing the risk of endometrial hyperplasia and cancer. - It can lead to changes in the endometrial lining, including **polyps** and hyperplasia, due to its estrogenic effects in the uterus. *Diabetes* - **Diabetes**, particularly type 2, is a risk factor for endometrial hyperplasia and cancer, not a protective factor. - It is associated with **increased insulin levels** and insulin-like growth factors, which can promote endometrial cell proliferation. *Delayed menopause* - **Delayed menopause** means a longer lifetime exposure to estrogen during the reproductive years. - Prolonged exposure to **unopposed estrogen** is a significant risk factor for endometrial hyperplasia, as it promotes endometrial proliferation.

Q: A woman who is not breast feeding her newborn child is advised to use a contraceptive method by:

6th postpartum week. ***6th postpartum week*** - For non-breastfeeding women, the **uterus typically involutes** by 6 weeks, and ovulatory cycles can resume as early as 4-6 weeks postpartum. - Due to the rapid return to fertility and the completion of immediate postpartum healing, contraceptive methods are generally recommended around the **6-week postpartum check-up**. *3rd postpartum month* - This is generally considered **too late** for initiating contraception in non-breastfeeding women as fertility can return much earlier. - Waiting until 3 months significantly increases the risk of **unintended pregnancy** because ovulation often occurs before the first postpartum menses. *3rd postpartum week* - While some women may ovulate early, it's generally **too soon** to initiate most contraceptive methods due to ongoing uterine involution and the risk of postpartum complications. - The risk of **thrombosis** is still elevated in the immediate postpartum period, making certain hormonal contraceptives (e.g., estrogen-containing methods) contraindicated. *6th postpartum month* - Similar to the 3rd postpartum month, this is generally **too late** to initiate contraception for non-breastfeeding women. - Prolonged delay significantly increases the likelihood of **unintended conception** during this period.

Q: Indications for removal of IUDs are all EXCEPT:

Cyclical menstrual bleeding. ***Cyclical menstrual bleeding*** - **Normal cyclical menstrual bleeding** is an expected physiological event and not an indication for IUD removal. - While IUDs can alter menstrual patterns (e.g., heavier or lighter bleeding), typical cyclical bleeding that is not excessively heavy, painful, or prolonged usually does not warrant removal. *Pregnancy with IUD* - If a **pregnancy occurs with an IUD in situ**, especially in the first trimester, the IUD should ideally be removed to reduce the risk of spontaneous abortion, preterm labor, or infection. - Removal is especially crucial if the strings are visible and accessible; if not, close monitoring is necessary. *Flaring up of salpingitis* - **Salpingitis (pelvic inflammatory disease - PID)** is a serious infection that can be exacerbated or initiated by the presence of an IUD, particularly during insertion or in individuals with pre-existing infections. - A confirmed or suspected flare-up of salpingitis necessitates IUD removal to control the infection and prevent further complications like infertility or ectopic pregnancy. *Perforation of uterus* - **Uterine perforation** is a serious complication that can occur during IUD insertion and requires immediate removal of the device. - Depending on the extent of perforation, it may lead to pain, hemorrhage, infection, or damage to surrounding organs.
