Clomiphene citrate primarily acts by:
सही उत्तर: ख) Stimulating Follicular Development
Clomiphene citrate is an antagonist that blocks the reuptake of serotonin in the pituitary gland, leading to increased production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which stimulates follicular development.

A 5-year-old child presents with an abdominal mass that crosses the midline and shows raised urinary vanillylmandelic acid (VMA) levels. Which of the following is the MOST likely diagnosis?
सही उत्तर: ख) Wilms Tumor
Raised VMA levels strongly suggest neuroblastoma, a common childhood malignancy arising from sympathetic nerve tissue. Wilms tumor can also cause abdominal masses but typically doesn't correlate with elevated VMA.

The typical karytype observed in a complete hydatidiform mole is:
सही उत्तर: ग) 69,XXX
A complete hydatidiform mole presents with a chimerism of paternal and maternal cells. The characteristic karyotype is 69,XXY which reflects the abnormal chromosomal makeup of the molar tissue - typically a single set of paternal chromosomes combined with a variable number of maternal chromosomes.

A pregnant woman at 32 weeks gestation presents with painless, recurrent, bright red vaginal bleeding. Which of the following is the MOST likely diagnosis?
सही उत्तर: ख) Miscarriage (Spontaneous Abortion)
Miscarriage (spontaneous abortion) is the most common cause of painless vaginal bleeding in the third trimester. While placenta previa can present with bleeding, it typically involves passage of blood clots and is usually associated with contractions. Bacterial vaginosis and uterine rupture are less likely given the presentation.

A 28-year-old female presents with persistent vaginal itching and a thick, white, curdy discharge. Microscopy reveals clue cells. Which of the following is the MOST likely diagnosis? a) Bacterial Vaginosis b) Candidiasis (Yeast Infection) c) Trichomoniasis d) Chlamydia infection
सही उत्तर: ख) b) Candidiasis (Yeast Infection)
The clinical presentation of a thick, white, curdy discharge with intense itching and clue cells is highly characteristic of candidiasis (yeast infection). While bacterial vaginosis can cause discharge, it typically has an odor. Trichomoniasis presents differently, and chlamydia usually asymptomatic.

A newborn infant born at 32 weeks gestation is diagnosed with respiratory distress syndrome (RDS). Which of the following interventions would be MOST important in the initial management of this infant? a) Administration of intravenous antibiotics b) Placement on a heated radiant warmer and mechanical ventilation c) Dietary supplementation with breast milk d) Application of vitamin D drops
सही उत्तर: ख) b) Placement on a heated radiant warmer and mechanical ventilation
RDS in preterm infants is primarily due to surfactant deficiency, leading to alveolar collapse. Mechanical ventilation and a heated radiant warmer are essential for support. Antibiotics aren't indicated, while breastmilk is not a solution to the primary respiratory problem.

A 32-year-old woman presents with symptoms suggestive of preterm labor at 34 weeks gestation. The WHO partograph shows that the cervical dilatation has progressed from 1 cm to 3cm over 4 hours, and the fetal heart rate remains reassuring. The next appropriate action according to the partograph is: a) Continue monitoring the fetal heart rate b) Administer oxytocin for augmentation of labor c) Immediately deliver the infant via vaginal delivery d) Send the patient to the operating room for a Cesarean section
सही उत्तर: ख) b) Administer oxytocin for augmentation of labor
The partograph’s action line moves with the alert line, indicating progression. The next step is to move the action line towards the alert line to arrest cervical dilation and prevent fetal distress - administering oxytocin for augmentation of labor.

A 6-month-old infant is brought to the clinic complaining of fever, lethargy, and poor feeding. Physical examination reveals hepatosplenomegaly. Which of the following investigations would be MOST crucial in confirming a diagnosis of acute rheumatic fever? a) Complete Blood Count (CBC) b) Serum Erythrocyte Sedimentation Rate (ESR) & C-Reactive Protein (CRP) c) Urine Analysis for Protein and Glucose d) Chest X-ray for Pneumonia
सही उत्तर: ख) b) Serum Erythrocyte Sedimentation Rate (ESR) & C-Reactive Protein (CRP)
The Jones criteria, the standard diagnostic tool for acute rheumatic fever, rely heavily on ESR and CRP. While a CBC is useful, ESR/CRP are critical indicators of inflammation strongly linked to rheumatic heart disease. The other options aren’t directly relevant to diagnosing this condition.

A pregnant woman presents with severe lower abdominal pain and vaginal bleeding. Initial investigations reveal a retroverted uterus, absent or hypoplastic cervix, and absent uterine horns. This presentation is MOST consistent with which of the following conditions? a) Polycystic Ovary Syndrome (PCOS) b) Mayer-Rokitansky-Kuster-Hauser (MRKH) Syndrome c) Ectopic Pregnancy d) Uterine Fibroids
सही उत्तर: ख) b) Mayer-Rokitansky-Kuster-Hauser (MRKH) Syndrome
MRKH syndrome is characterized by the absence of a uterus and cervix, often with a retroverted uterus. The other options are less likely given the specific presentation – PCOS typically doesn’t cause absent uterine structures, ectopic pregnancy presents with different pain patterns, and fibroids usually have a more typical uterus.

Which of the following is the most accurate description of ‘kernicterus’ in newborns? a) Inflammation of the liver caused by bacterial infection. b) Accumulation of bilirubin in the blood that causes neurological damage. c) A type of congenital heart defect resulting from abnormal fetal development. d) Excessive protein intake leading to kidney failure.
सही उत्तर: ख) b
Kernicterus (b) is the clinical manifestation of severe hyperbilirubinemia in newborns. Elevated levels of unconjugated bilirubin accumulate in the blood and cross the blood-brain barrier, causing neurological damage, particularly affecting the basal ganglia. The other options describe entirely different conditions.
