UPSC-CMS 2016 Practice Questions

Q: Menopause is associated with the following except:

Delusion. ***Delusion*** - Delusions are a feature of **psychotic disorders** and are not directly associated with the physiological changes of menopause. - While menopause can affect mood and cognitive function, it does not typically cause **psychotic symptoms** like delusions. *Loss of libido* - The decline in **estrogen levels** during menopause can lead to vaginal dryness and discomfort during intercourse, which can contribute to a loss of libido. - Hormonal changes also directly impact sexual desire, making it a common menopausal symptom. *Ischemic heart disease* - Estrogen has a **cardioprotective effect**, and its decline after menopause increases women's risk for **ischemic heart disease**. - The absence of estrogen contributes to changes in lipid profiles and endothelial function, predisposing women to cardiovascular events. *Osteoporosis* - Estrogen plays a crucial role in maintaining **bone density**, and its reduction during menopause accelerates bone loss. - This loss of bone mass significantly increases the risk of **osteoporosis** and fractures in postmenopausal women.

Q: Which one of the following conditions simulates the menstrual pattern of pain?

Adenomyosis. ***Adenomyosis*** - Adenomyosis is characterized by the presence of **endometrial tissue within the myometrium**, which responds cyclically to hormonal changes, similar to normal endometrium. - This leads to **dysmenorrhea** (painful periods) and **menorrhagia** (heavy bleeding) due to the cyclic growth and shedding of endometrial tissue within the uterine muscular wall. *Intramural fibroid* - Intramural fibroids are **benign uterine tumors** within the muscular wall that can cause heavy bleeding and pressure symptoms. - While they can cause pain and heavy bleeding, the pain is typically not directly related to a **menstrual pattern of cyclic pain** in the same manner as adenomyosis, as the fibroid tissue itself does not undergo cyclic shedding. *Granulosa cell tumour of ovary* - This is a **sex cord-stromal tumor** of the ovary that often produces **estrogen**, which can lead to irregular uterine bleeding or postmenopausal bleeding. - It does not directly cause pain that simulates a **regular menstrual pattern**, as its hormonal effects are typically sustained or irregular, not cyclic in the way normal menstruation or adenomyosis pain is. *Haematometra* - Haematometra is the accumulation of **menstrual blood within the uterus** due to an obstruction of the outflow tract, such as cervical stenosis. - This condition causes increasing pain and distension as blood accumulates, but the pain is usually **constant or progressively worsening**, not cyclic in a pattern that simulates normal menstruation, and typically leads to **amenorrhea** rather than patterned bleeding.

Q: Which of the undermentioned conditions does not cause postmenopausal vaginal bleeding?

Benign cystic teratoma of ovary. ***Benign cystic teratoma of ovary*** - A **benign cystic teratoma** of the ovary is a germ cell tumor that typically does **not cause hormonal changes** leading to vaginal bleeding. - While it can cause symptoms such as **abdominal pain** or a palpable mass, it is not directly associated with postmenopausal vaginal bleeding. *Carcinoma of cervix* - **Cervical cancer** is a well-known cause of both **intermenstrual** and **postmenopausal vaginal bleeding**, especially following intercourse. - The abnormal growth of cells on the cervix can be fragile and bleed easily, leading to the symptom. *Senile vaginitis* - Also known as **atrophic vaginitis**, this condition occurs due to the **thinning and inflammation** of the vaginal walls due to decreased estrogen levels after menopause. - The fragile, dry tissues can easily tear and bleed, leading to postmenopausal bleeding or spotting. *Prolapse of uterus with decubitus ulcer* - A **decubitus ulcer** can form on the prolapsed cervix or vaginal wall due to **chronic friction and irritation**, particularly in cases of severe uterine prolapse. - The raw, ulcerated surface readily **bleeds**, especially with minor trauma or straining, causing postmenopausal vaginal bleeding.

Q: Defective fusion of the Mullerian ducts may give rise to which of the following?

Uterus bicornis unicollis. ***Uterus bicornis unicollis*** - This condition results from the **incomplete fusion** of the two Müllerian ducts, leading to a uterus with a **septum** or two distinct uterine cavities but a single cervix and vagina. - The Müllerian ducts are embryological structures that develop into the **female reproductive tract**, including the uterus, fallopian tubes, cervix, and upper two-thirds of the vagina. *Imperforate anus* - This congenital condition is due to the **failure of the anal membrane to rupture** during development, not related to Müllerian duct fusion. - It affects the **gastrointestinal tract** and is not derived from Müllerian structures. *Absence of the ovaries* - The **ovaries** develop from the **gonadal ridges** and are distinct from the Müllerian ducts; therefore, their absence is not due to defective Müllerian fusion. - Conditions like **gonadal dysgenesis** can lead to absent or streak ovaries. *Imperforate hymen* - An imperforate hymen results from the failure of the **hymen to canalize** during fetal development, leading to an obstruction of the vaginal introitus. - The hymen is formed from the **urogenital sinus**, which is embryologically distinct from the Müllerian ducts.

Q: For a woman who has had unprotected intercourse two days ago, which one of the following emergency contraceptive methods is LEAST preferred as first-line emergency contraception?

Yuzpe regimen. ***Yuzpe regimen*** - The **Yuzpe regimen** uses higher doses of combined oral contraceptive pills, leading to more side effects like nausea and vomiting and generally lower efficacy compared to newer methods. - It involves taking two doses of estrogen and progestin, making it less convenient and less effective, especially after **48 hours**, compared to progestin-only or ulipristal acetate pills. *Levonorgestrel 1.5 mg* - **Levonorgestrel (LNG)** 1.5 mg, taken as a single dose, is a highly effective and widely recommended first-line emergency contraceptive within **72 hours** of unprotected intercourse. - It primarily works by **inhibiting or delaying ovulation**, without causing significant side effects in most women. *LNG IUD* - While an **LNG IUD** can be used as emergency contraception, it is not typically considered a first-line *oral* method; it is placed by a healthcare provider and can provide long-term contraception. - It is effective if inserted within **5 days** of unprotected intercourse, making it a highly effective option that also offers ongoing contraception. *Ulipristal acetate* - **Ulipristal acetate (UPA)** is a highly effective emergency contraceptive, even up to **120 hours (5 days)** after unprotected intercourse. - It works by delaying or inhibiting ovulation and is generally more effective than levonorgestrel, especially when taken more than **72 hours** post-coitally.

Q: Deep transverse arrest of head in labour occurs in:

Android pelvis. ***Android pelvis*** - An **android pelvis** has a heart-shaped inlet with a narrow forepelvis, causing the fetal head to engage in a transverse or occiput posterior position. - The narrow midpelvis and convergent side walls in an android pelvis can lead to deep **transverse arrest**, as the fetal head cannot easily rotate to the anterior position. *Anthropoid pelvis* - The **anthropoid pelvis** is characterized by a long anteroposterior diameter and a relatively narrow transverse diameter. - This pelvic shape typically favors engagement in the **occiput anterior** or **occiput posterior** positions, making deep transverse arrest less common. *Platypelloid pelvis* - A **platypelloid pelvis** has a wide transverse diameter and a very short anteroposterior diameter, leading to a flattened shape. - This shape often results in the fetal head engaging in the **transverse position**, but arrest usually occurs at the inlet rather than deep in the pelvis, or the head fails to engage at all. *Gynaecoid pelvis* - The **gynaecoid pelvis** is considered the ideal female pelvis, with a rounded inlet and adequate diameters in all planes. - This shape allows for easy engagement and rotation of the fetal head, making deep **transverse arrest** very unlikely.

Q: Early deceleration of foetal heart rate in labour is due to:

Foetal head compression. ***Foetal head compression*** - **Early decelerations** are a direct result of **foetal head compression** during uterine contractions, leading to increased intracranial pressure. - This pressure causes a **reflex vagal response**, resulting in **slowing of the foetal heart rate** which mirrors the contraction pattern. *Hyperpyrexia* - **Maternal hyperpyrexia** typically causes **foetal tachycardia**, which is an elevated heart rate, not deceleration. - This is a response to the increased maternal and foetal metabolic rate and can be a sign of infection. *Umbilical cord compression* - **Umbilical cord compression** usually leads to **variable decelerations**, which are sharp, abrupt drops in heart rate not uniformly related to contractions. - This occurs due to transient occlusion of the umbilical vessels, reducing blood flow to the foetus. *Congenital heart block* - **Congenital heart block** is a persistent bradycardia (slow heart rate) that is present throughout labour and is not directly linked to uterine contractions. - It is a structural abnormality of the foetal cardiac conduction system.

Q: McRoberts manoeuvre is used during labour for management of:

Shoulder dystocia. ***Shoulder dystocia*** - **McRoberts manoeuvre** involves sharp flexion of the maternal thighs against the abdomen, which straightens the **sacrum** and rotates the **symphysis pubis** anteriorly. - This maneuver increases the functional size of the pelvic outlet and helps to dislodge the impacted fetal shoulder in cases of **shoulder dystocia**. - It is the **first-line intervention** for managing shoulder dystocia and is successful in resolving the majority of cases. *Delivery of after coming head of breech* - Management of an after-coming head in breech delivery typically involves maneuvers like the **Mauriceau-Smellie-Veit** maneuver or **Prague maneuver**. - **McRoberts manoeuvre** does not directly facilitate the delivery of the fetal head in a breech presentation. *Normal labour to assist extension of head* - In normal labor, the fetal head typically delivers by **extension** as it passes under the symphysis pubis, and no specific maneuver is usually required. - McRoberts manoeuvre is a specific intervention for a complication (**shoulder dystocia**), not a routine aid for head extension during normal delivery. *Extended arms of breech during assisted breech delivery* - Extended arms in a breech presentation are managed by maneuvers designed to free the arms, such as **Løvset's maneuver**. - **McRoberts manoeuvre** primarily addresses shoulder impaction, not arm entrapment in breech delivery.

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.

Q: Polyhydramnios is not caused by which one of the following?

Single kidney. ***Single kidney*** - A single kidney or other renal agenesis conditions typically lead to **oligohydramnios**, not polyhydramnios, because fetal urine production is reduced or absent. - The fetal urinary system is crucial for maintaining amniotic fluid volume, and its malfunction results in decreased fluid. *Spina bifida* - **Neural tube defects** such as spina bifida can contribute to polyhydramnios by affecting fetal swallowing mechanisms or increasing fluid secretion from exposed meninges. - While not the most common cause, severe forms can impair neural control over fetal fluid regulation. *Oesophageal atresia* - This condition prevents the fetus from **swallowing amniotic fluid**, leading to its accumulation in the amniotic sac. - Fetal swallowing is a primary mechanism for amniotic fluid reabsorption, and its mechanical obstruction results in polyhydramnios. *Anencephaly* - **Anencephaly** is a severe **neural tube defect** where the brain and skull fail to develop, often leading to impaired fetal swallowing and excessive urination. - The exposed meninges can also leak cerebrospinal fluid into the amniotic sac, further contributing to polyhydramnios.
