Beta-thalassemia major often manifests clinically around what age?
सही उत्तर: घ) 10-12 years
Symptoms of beta-thalassemia major typically become apparent as the child’s iron stores are depleted and their body can no longer produce enough hemoglobin. This often occurs between 5-7 years of age, though there is variability. The other options represent earlier or later stages.

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.

The Krebs cycle (Citric Acid Cycle) primarily functions to:
सही उत्तर: ख) B. Convert pyruvate into acetyl-CoA, generating NADH and FADH2.
The Krebs cycle's main role is to oxidize acetyl-CoA, releasing carbon dioxide and producing high-energy electron carriers (NADH and FADH2) which then fuel oxidative phosphorylation – the primary ATP production pathway. Options A and D are incorrect as they describe unrelated processes.

A 60 kg adult presents with 30% Total Body Surface Area (TBSA) burns. Using the Parkland formula, how many mL of intravenous fluid should be administered hourly for the first 8 hours? (Parkland formula: 4 mL/kg/ % TBSA x Hourly Rate)
सही उत्तर: ख) 900 ml
The Parkland Formula dictates 4ml/kg/%TBSA. In this case: 4ml/kg/30% = 4 * 0.3 = 1.2 ml/kg/hour. For a 60 kg patient, the total volume would be 1.2 * 60 = 72 ml per hour. Therefore, the answer is 900ml for the first 8 hours (which equates to approximately 600ml/hr).

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.

Which of the following is the primary function of peristaltic waves in the small intestine? (a) To mix chyme with gastric juices. (b) To propel digested food towards the stomach. (c) To absorb nutrients from the intestinal lumen. (d) To regulate blood flow to the intestinal mucosa.
सही उत्तर: ख) (b) To propel digested food towards the stomach.
Peristaltic waves are rhythmic contractions and relaxations of smooth muscle in the intestines that move chyme along the digestive tract. Mixing with gastric juices is a consequence of this movement. Options (b), (c), and (d) describe other functions.

The Bohr effect describes a shift in hemoglobin’s affinity for oxygen. Which of the following conditions *primarily* promotes a positive Bohr effect? (a) Increased blood pH. (b) Decreased blood carbon dioxide concentration. (c) Elevated 2,3-diphosphoglycerate (2,3-DPG) levels. (d) Increased temperature.
सही उत्तर: ग) (c) Elevated 2,3-diphosphoglycerate (2,3-DPG) levels.
The Bohr effect states that increased H+ concentration (lower pH), which occurs in tissues with high CO2 and metabolic activity, decreases hemoglobin’s affinity for oxygen. Option (a) is the key factor here. Option (b) increases affinity; option (c) increases affinity; and option (d) has a minor effect.
