Question 71: The example of de-professionalization of medicine is widely seen in India in the form of:
- A. Providing Primary Health Care
- B. Medical malpractice by doctors
- C. Rural internship by doctors
- D. Irrational use of antibiotics by doctors (Correct Answer)
Explanation: ***Irrational use of antibiotics by doctors*** - The **widespread irrational use of antibiotics** represents de-professionalization as it reflects the **routinization and degradation of professional medical judgment** across the healthcare system in India. - This practice demonstrates **erosion of evidence-based professional standards** where prescribing decisions are driven by patient demand, commercial pressures, or convenience rather than clinical indication, leading to **antibiotic resistance** as a major public health threat. - Unlike isolated incidents of malpractice, this is a **systemic pattern** that undermines the specialized knowledge and autonomous decision-making that define medical professionalism. - It exemplifies how **professional medical practice has been reduced** to routine, non-scientific prescribing patterns, characteristic of de-professionalization. *Providing Primary Health Care* - Providing **primary health care** is a core professional medical function and represents appropriate medical practice, not de-professionalization. - It aligns with professional responsibility to ensure accessible, comprehensive healthcare services as the **first point of contact** in the health system. *Medical malpractice by doctors* - While **medical malpractice** involves professional failings, it refers to **individual deviations** from the standard of care in specific cases, addressed through legal mechanisms. - De-professionalization refers to **systemic degradation** of professional standards across the field, not isolated instances of negligence or error. *Rural internship by doctors* - **Rural internship** is a structured component of medical education designed to enhance professional competence and expose doctors to diverse healthcare challenges in underserved areas. - It represents **professional development** and strengthening of health services, not erosion of professional standards.
Question 72: Consider the following: 1. Literacy rate 2. Life expectancy at birth 3. Life expectancy at the age of one year 4. Infant mortality Which of the above are the components of Physical Quality of Life Index (P.Q.L.I.)?
- A. 2 and 4
- B. 1 and 2
- C. 1 and 4 only
- D. 1, 2 and 4 (Correct Answer)
Explanation: ***1, 2 and 4*** - The **Physical Quality of Life Index (PQLI)** developed by Morris David Morris includes three core components: 1. **Literacy rate** (basic literacy at age 15+) 2. **Infant mortality rate** (per 1000 live births) 3. **Life expectancy at age one year** (not at birth) - While the question lists "life expectancy at birth" (option 2), the PQLI technically uses **life expectancy at age one**. However, since option 3 (life expectancy at age one) is not included in this answer choice and both are closely related measures of population health, this option represents the three domains covered by PQLI: **education (literacy), health outcomes (infant mortality), and longevity (life expectancy)**. - Components **1, 2, and 4** together capture the multidimensional aspects of quality of life. *2 and 4* - This option is incomplete as it excludes **literacy rate**, which is a fundamental component of PQLI. - Education is a critical dimension of quality of life measurement. *1 and 2* - This option excludes **infant mortality rate**, which is one of the three core components of PQLI. - Infant mortality is essential for measuring health status in the population. *1 and 4 only* - While this includes two correct components (**literacy rate** and **infant mortality**), it excludes the life expectancy measure entirely. - PQLI requires all three dimensions: education, mortality, and longevity.

Question 71: Face to pubes delivery occurs in which of the foetal position?
- A. Occipito-sacral (Correct Answer)
- B. Brow presentation
- C. Mentoanterior
- D. Mentoposterior
Explanation: ***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.
Question 72: The peak level of human chorionic gonadotropin in normal pregnancy occurs between:
- A. 30 to 40 days after pregnancy
- B. 100 to 120 days after pregnancy
- C. 10 to 12 days after pregnancy
- D. 60 to 70 days after pregnancy (Correct Answer)
Explanation: ***60 to 70 days after pregnancy*** - Peak **hCG levels** in normal singleton pregnancies are typically observed between **9-10 weeks of gestation**, which corresponds to approximately **63-70 days after the last menstrual period (LMP)** or fertilization. - This period marks the highest physiological levels of hCG, crucial for maintaining the **corpus luteum** and early pregnancy. *30 to 40 days after pregnancy* - At this stage (approximately 4-5 weeks gestation), hCG levels are **rising rapidly** but have not yet reached their peak. - While detectable and increasing, the concentration of hCG is significantly lower than what is observed at 9-10 weeks. *100 to 120 days after pregnancy* - By this time (approximately 14-17 weeks gestation), **hCG levels have already peaked** and are typically declining to a lower, somewhat stable plateau for the remainder of the pregnancy. - This period is well past the peak hCG concentration. *10 to 12 days after pregnancy* - This period roughly corresponds to the time of **implantation** and the very early stages of hCG production, making levels **relatively low** but detectable. - HCG levels are just beginning their rapid ascent following implantation and are far from their peak concentration.
Question 73: The second most common site for endometriosis after the ovary is:
- A. Round ligaments
- B. Fallopian tubes
- C. Outer surface of uterus
- D. Peritoneum of the pouch of Douglas (Correct Answer)
Explanation: ***Peritoneum of the pouch of Douglas*** - The **pouch of Douglas** (rectouterine pouch) is the most common site for endometriosis after the ovaries, where endometrial tissue deposits frequently occur. - Due to its dependent position in the pelvis, **shed endometrial cells** from retrograde menstruation are thought to accumulate here. *Round ligaments* - While endometriosis can occur in the round ligaments, it is far **less common** than in the cul-de-sac or on the ovaries. - Endometriotic lesions in this location might mimic other conditions, making diagnosis challenging. *Fallopian tubes* - Endometriosis can affect the fallopian tubes, leading to conditions like **hydrosalpinx** or adhesion formation, but it is not the second most common site. - The tubes are more frequently involved by **pelvic inflammatory disease** or ectopic pregnancy. *Outer surface of uterus* - Endometriosis on the outer surface of the uterus (serosa) is possible, but **less common** than in the ovaries or the pouch of Douglas. - Lesions here can contribute to **adhesions** between the uterus and adjacent structures.
Question 74: A patient who just delivered at home presents with a third degree perineal tear. You will do the repair:
- A. after 24 hours.
- B. after 6 weeks
- C. immediately (Correct Answer)
- D. after 3 months
Explanation: ***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**.
Question 75: The gestational sac is first visible on transvaginal USG by:
- A. 49 days
- B. 30 days
- C. 42 days
- D. 35 days (Correct Answer)
Explanation: ***35 days*** - A **gestational sac** can first be reliably visualized via **transvaginal ultrasonography** at approximately **35 days** after the last menstrual period (around **5 weeks gestational age**). - At this stage, it appears as a small, anechoic (fluid-filled) structure within the **endometrial cavity**, indicating an early intrauterine pregnancy. - This corresponds to a **β-hCG level** of approximately **1000-2000 mIU/mL**, which is the discriminatory zone for transvaginal ultrasound. *30 days* - At **30 days** (approximately 4 weeks + 2 days gestational age), the gestational sac is typically **too small** to be consistently visualized even with transvaginal ultrasound. - While some early sacs may be detected, **30 days** is generally considered **too early** for reliable detection in most cases. - Detection at this stage would be inconsistent and not the standard timeframe cited in obstetric practice. *42 days* - By **42 days** (6 weeks gestational age), the gestational sac is well-established and clearly visible. - At this point, a **yolk sac** is almost always present within the gestational sac, and often a **fetal pole** may be identified. - This represents a later stage, not the *first* time the gestational sac can be detected. *49 days* - By **49 days** (7 weeks gestational age), not only is the **gestational sac** clearly visible, but a **yolk sac** and **fetal pole** with **cardiac activity** are typically identifiable. - This time frame represents a much later stage of pregnancy visualization, well beyond the initial appearance of the gestational sac.
Question 76: A 30-year-old housewife reports with 6 months amenorrhea. Her serum LH and FSH are high with low estradiol levels. What is the most likely cause of amenorrhea in this context?
- A. Premature menopause (Correct Answer)
- B. Polycystic ovarian disease
- C. Exercise induced
- D. Pituitary tumour
Explanation: ***Premature menopause*** - **High LH and FSH** with **low estradiol** levels indicate primary ovarian failure, where the ovaries are no longer responding to pituitary stimulation. - In a 30-year-old woman, this ovarian failure presenting as 6 months of amenorrhea is consistent with **premature menopause** (also known as premature ovarian insufficiency). *Polycystic ovarian disease* - Characterized by **high LH:FSH ratio** (typically LH higher than FSH) and **high estrogen** due to peripheral conversion of androgens, which is contrary to the low estradiol observed here. - Presents with features like **hirsutism**, acne, and menstrual irregularities, but typically not with primary ovarian failure. *Exercise induced* - **Exercise-induced amenorrhea** (hypothalamic amenorrhea) is characterized by **low or normal LH and FSH** and **low estradiol**, reflecting inadequate GnRH pulsatility from the hypothalamus, not primary ovarian failure. - This condition is a form of **secondary amenorrhea** due to a disruption in the hypothalamic-pituitary-ovarian axis, often seen in athletes or people with low body fat. *Pituitary tumour* - A **pituitary tumor** can cause amenorrhea by various mechanisms, such as secreting prolactin (prolactinoma) which **inhibits GnRH**, leading to **low LH, FSH, and estradiol**. - Alternatively, a large non-functional tumor might cause hypopituitarism, also resulting in **low gonadotropins and estradiol**, which contradicts the high LH and FSH seen in this patient.
Question 77: The Pearl index of contraceptive failure is expressed as a rate per
- A. 1000 women-years
- B. 1 woman-year
- C. 10 women-years
- D. 100 women-years (Correct Answer)
Explanation: ***100 women-years*** - The **Pearl Index** is a common measure of contraceptive failure rate, expressed as the number of pregnancies per **100 women-years** of exposure. - This metric allows for standardized comparison of contraceptive effectiveness across different methods and populations. *1000 women-years* - While other epidemiological rates might be expressed per 1000 person-years, the standard for the **Pearl Index** is specifically per 100 women-years. - Using 1000 would significantly underestimate the commonly reported failure rates of contraceptives. *1 woman-year* - Expressing the rate per **1 woman-year** would result in very small, often fractional, numbers that are difficult to interpret and compare. - The larger base of 100 women-years provides a more practical and understandable scale for reporting contraceptive failure. *10 women-years* - This increment is not the recognized standard for the **Pearl Index**. - Using 10 women-years would also make the reported failure rates less comparable with established data and harder to interpret clinically.
Question 78: Match List-I with List-II and select the correct answer using the code given below the Lists:
- A. A→4 B→1 C→3 D→2
- B. A→2 B→1 C→3 D→4
- C. A→2 B→3 C→1 D→4 (Correct Answer)
- D. A→4 B→3 C→1 D→2
Explanation: ***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.
