Which of the following statements accurately describes the role of intrinsic factor in gastric secretion? (a) It stimulates the production of pepsinogen. (b) It neutralizes stomach acid. (c) It binds to vitamin B12 for absorption in the ileum. (d) It increases the motility of the stomach muscles.
सही उत्तर: ग) (c) It binds to vitamin B12 for absorption in the ileum.
Intrinsic factor is a glycoprotein essential for the absorption of vitamin B12. It binds with B12 in the stomach and facilitates its transport across the intestinal wall to the ileum where it's absorbed. Options (a), (b), and (d) describe actions of other gastric hormones or processes.

The glomerular filtration rate (GFR) is a key indicator of kidney health. Which of the following factors *directly* increases GFR? (a) Increased secretion of antidiuretic hormone (ADH). (b) Decreased blood pressure in the afferent arteriole. (c) Increased resistance in the efferent arteriole. (d) Elevated levels of plasma protein concentration.
सही उत्तर: ख) (b) Decreased blood pressure in the afferent arteriole.
GFR is directly influenced by the hydrostatic pressure difference between the glomerulus and Bowman's capsule. A decrease in blood pressure in the afferent arteriole (the vessel bringing blood *to* the glomerulus) increases this pressure gradient, thus boosting GFR. Option (a) reduces GFR; option (c) opposes it; and option (d) decreases GFR.

Which of the following best describes the primary function of erythrocytes (red blood cells)? (a) To transport oxygen throughout the body. (b) To initiate and coordinate immune responses. (c) To synthesize hormones within the endocrine system. (d) To contract muscles for movement.
सही उत्तर: क) (a) To transport oxygen throughout the body.
Erythrocytes are specialized cells designed to carry oxygen. The hemoglobin they contain is responsible for this function. Options (b), (c), and (d) describe functions of other cell types - lymphocytes, hormones, and muscle fibers respectively.

Following fertilization, a monozygotic twin embryo divides between days 8 and 12. What is the most likely outcome?
सही उत्तर: ख) B. Monochorionic Diamniotic twins
The division of a monozygotic twin embryo within this timeframe typically results in monochorionic diamniotic (MCD) twins, where they share a placenta but have separate amniotic sacs. Dichorionic Diamniotic twins result from separate initial fertilizations – options C and D are incorrect.

The majority of cases of Trisomy 21 originate from?
सही उत्तर: ग) C. Non-disjunction during oogenesis
Trisomy 21 is primarily caused by non-disjunction – the failure of chromosome 21 to separate properly during oogenesis, leading to an extra copy of the chromosome. Advanced maternal age increases the risk but doesn't cause trisomy itself – options A and D are incorrect.

A woman presents with recurrent painless second-trimester pregnancy loss accompanied by painless cervical dilatation. Which treatment strategy would be most appropriate in this scenario?
सही उत्तर: ख) B. Immunosuppressive therapy followed by intrauterine interferon alpha injection
Immunosuppressive therapy, combined with interferon alpha (as per IADPSG guidelines), is now considered standard treatment for recurrent pregnancy loss due to antiphospholipid syndrome. While progesterone supplementation might be considered, it's not the primary intervention in this specific case – options A and C are incorrect.

A newborn infant diagnosed with persistent ductus arteriosus (PDA) would most likely require treatment with which of the following medications to maintain patency of the ductus?
सही उत्तर: क) A. Furosemide
Furosemide is a diuretic that increases blood flow, maintaining PDA patency. Nifedipine is a calcium channel blocker and not used for PDA specifically. Apamsone is a drug used for treating hypertension. Prostaglandin E1 stimulates ductal dilation – the correct answer.

A patient sustains blunt abdominal trauma and subsequently develops left shoulder-tip pain. This symptom is most likely due to:
सही उत्तर: ख) Diaphragmatic irritation
The classic presentation of diaphragmatic irritation following splenic injury is ipsilateral (left shoulder-tip) pain, a referred sensation. Splenic infarction and hepatic abscess would not typically present with this specific pain pattern.

A 2-year-old child presents with symptoms consistent with bronchiolitis, including wheezing and rapid breathing. Which of the following is the MOST appropriate initial treatment?
सही उत्तर: घ) D) Forced expiratory maneuvers to clear airways
Supplemental oxygen via nasal cannula is the initial and mainstay treatment for bronchiolitis. Corticosteroids are not routinely used due to limited evidence of benefit, antibiotics aren’t appropriate for viral infections and forced expiratory maneuvers can be harmful.

A newborn infant is diagnosed with omphalocele. Which of the following interventions is MOST crucial for managing this condition?
सही उत्तर: ग) C) Nutritional support via intravenous fluids alone
Surgical repair to cover the omphalocele and minimize contamination is the cornerstone of management. This prevents further complications. Ligation isn't performed, nutritional support isn’t a long-term solution and merely observing for respiratory distress doesn't address the underlying problem.
