A pregnant woman presents with vaginal bleeding and lower abdominal pain. Her ultrasound reveals a gestational sac with a yolk sac edema. What is the MOST likely diagnosis?
सही उत्तर: ग) Hydatidiform Mole
The description – gestational sac, yolk sac edema – strongly suggests a hydatidiform mole (also known as molar pregnancy). The other options don’t fit the classic presentation. Miscarriage can occur at any stage but lacks the specific ultrasound finding; ectopic pregnancy presents with pain and bleeding but without the characteristic mass; placental abruption causes sudden severe pain.

A newborn presents with a large, tense anterior fontanelle that is markedly depressed. Which of the following findings would MOST strongly suggest imminent cephalohematoma formation?
सही उत्तर: ख) B) A firm, non-tender mass beneath the scalp skin
The description of a large, tense anterior fontanelle suggests increased intracranial pressure. Palpable subgaleal hematomas (thin, fluid-filled collections under the scalp) are a common finding in this scenario as blood accumulates around the fontanelle. Options B and D describe alternative findings related to cephalohematoma formation.

In the context of neonatal resuscitation, what is the primary purpose of administering oxygen at a rate of 2-3 mL/kg/min via nasal cannula?
सही उत्तर: घ) D) To prevent aspiration of meconium
The administration of 2-3 mL/kg/min via nasal cannula provides supplemental oxygen, aiming for adequate oxygenation and promoting improved oxygen saturation. This is the standard initial approach in neonatal resuscitation. Options A, B, and D describe alternative interventions or their purposes.

According to IADPSG guidelines, what is the key diagnostic criterion for diagnosing gestational diabetes mellitus (GDM) based on a 75g OGTT?
सही उत्तर: ग) C) A 2-hour postprandial value >180mg/dL
IADPSG utilizes a specific two-step protocol: a fasting glucose and then a 1-hour postprandial test. The diagnostic criteria involve a 2-hour value exceeding 180 mg/dL. Options A, C, and D represent alternative approaches used in other diabetic diagnostic guidelines.

Which of the following best describes the primary function of the Wharton’s duct in neonates?
सही उत्तर: ख) B) Drainage of breast milk into the oral cavity
The Wharton’s ducts are responsible for draining colostrum, the first milk produced by a mother, into the newborn’s mouth. This ensures immediate nutrient and antibody transfer – the primary function. Options A, C, and D describe alternative roles or substances, not the specific drainage mechanism of the Wharton’s duct.

Approximately what percentage of cases of Trisomy 21 result from nondisjunction during oogenesis?
सही उत्तर: घ) 80%
Around 80-90% of trisomy 21 cases are due to nondisjunction occurring in the mother's egg cell (oocyte), leading to an extra copy of chromosome 21. The remaining cases occur through nondisjunction during spermatogenesis or fertilization.

Phototherapy is used to treat hyperbilirubinemia in newborns. Primarily, it reduces serum bilirubin levels by converting it into:
सही उत्तर: ख) Stercobilin
Phototherapy effectively decreases bilirubin levels by converting indirect (unconjugated) bilirubin to direct (conjugated) bilirubin, which is then excreted in the urine as stercobilin. The other options are incorrect pathways of bilirubin metabolism.

A 5-year-old child presents with small vesicles on his hands, feet, and oral mucosa. Based on this presentation, what is the MOST probable diagnosis?
सही उत्तर: ग) Hand-foot-and-mouth disease
Hand-foot-and-mouth disease (HFMD) classically presents with vesicles in these locations. Measles typically causes a maculopapular rash primarily on the trunk and extremities, chickenpox has larger blisters, and roseola usually involves a high fever with a small, diffuse pink spot rash.

A 28-year-old pregnant woman presents with sudden onset of severe pain in a myomatous polyp during the second trimester. What is the MOST likely explanation for this presentation?
सही उत्तर: क) Acute hemorrhage
Acute hemorrhage is the most common cause of acute pain in a myomatous polyp during the second trimester due to the increased blood flow and potential for uterine contractions. The other options are less likely: Calcification is a chronic process, infection is possible but less frequent, and vascular thrombosis can occur but doesn’t usually present with sudden severe pain.

A pregnant woman presents with vaginal bleeding and lower abdominal pain at 32 weeks gestation. Initial ultrasound reveals a gestational choriocarcinoma with multiple metastases. Which of the following is the MOST common distant metastasis site for gestational choriocarcinoma?
सही उत्तर: ख) Lungs
The lungs are the most frequent site of distant metastasis for gestational choriocarcinoma (approximately 60-80% of cases). The brain (approximately 20-30%), bone marrow, and liver represent less common sites. The tempting option of ‘Brain’ is plausible due to its vascularity but statistically less likely compared to lung metastases.
