A 5-year-old boy presents with palpable purpura on his buttocks and legs, joint pain, abdominal pain, and hematuria. Which of the following is the most likely diagnosis?
सही उत्तर: ग) Henoch-Schönlein Purpura (HSP)
Post-streptococcal glomerulonephritis is a common childhood illness triggered by a streptococcal infection and frequently presents with these symptoms. HSP is also possible, but the specific clinical presentation aligns best with post-streptococcal. The other options are less likely given the combination of findings.

Which of the following best describes the primary cause of most cases of Trisomy 21?
सही उत्तर: ग) Nondisjunction during meiosis II
Nondisjunction during meiosis II is the most common mechanism by which an extra copy of chromosome 21 enters into a gamete and subsequently into the developing embryo, leading to Trisomy 21. Options like mosaicism or chromosomal translocation result in different genetic alterations.

In a newborn suspected of having cystic fibrosis, which laboratory test would be MOST definitive?
सही उत्तर: ख) B. Sweat Chloride Test
The sweat chloride test is the gold standard for diagnosing cystic fibrosis due to its ability to detect abnormally high levels of chloride in sweat, reflecting impaired exocrine gland function.

A 12-year-old girl presents with a sudden onset of bright red ‘slapped cheek’ rash along with joint pain. Laboratory tests reveal elevated levels of anti-Ro/SSA antibodies. Which diagnosis is MOST likely?
सही उत्तर: क) Systemic Lupus Erythematosus (SLE)
The characteristic 'slapped cheek' rash and positive anti-Ro/SSA antibodies strongly suggest Rosacea, a condition frequently associated with joint pain. SLE presents similarly but typically has more systemic symptoms. JIA is characterized by inflammatory arthritis without the specific facial rash. Psoriasis usually does not present with this particular rash.

A newborn infant is diagnosed with a murmur on cardiac auscultation. Echo cardiography reveals an atrial septal defect (ASD). What is the MOST common clinical presentation associated with ASD in infancy?
सही उत्तर: क) Cyanosis
Cyanosis is the most common clinical presentation of ASD due to left-to-right shunting of blood, leading to increased oxygen saturation. Hypotension and diaphoretic skin are less typical findings. Progressive pulmonary hypertension occurs in later stages.

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 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.
