What is the significance of 'Grey Turner's Sign'?
सही उत्तर: ख) B. A bluish discoloration of the flanks caused by retroperitoneal hemorrhage, often associated with kidney injuries
Grey Turner's sign is characterized by a sudden appearance of blue-grey discoloration of the flanks, typically due to retroperitoneal hemorrhage – often seen in severe kidney injuries following blunt abdominal trauma. It’s not related to any specific surgical condition.

A patient presents with significant abdominal pain, nausea, and vomiting following a recent bout of diarrhea. Initial laboratory results show elevated amylase and lipase levels. Which of the following is the MOST immediate management step?
सही उत्तर: ख) B. Initiate intravenous fluid resuscitation and electrolyte correction
In acute pancreatitis, the primary concern is dehydration and electrolyte imbalance due to significant fluid loss through vomiting. Initial management focuses on supportive care – IV fluids and electrolytes are crucial before investigating the cause. CT scans are typically delayed until stabilization.

Which of the following structures is primarily responsible for the sensation of touch and pressure in the hand?
सही उत्तर: ख) B. Median Nerve
The median nerve, specifically its branches (e.g., the posterior interosseous nerve), carries sensory information related to fine touch and pressure in the hand’s palm and fingers. The ulnar and radial nerves primarily transmit motor functions and some sensory aspects like pain and temperature.

What is the primary goal of therapeutic phlebotomy in severe pre-eclampsia?
सही उत्तर: ग) Remove excess extracellular fluid to counteract hypertension
Decreasing intracranial pressure (option 2) is the primary goal, achieved by reducing cerebral perfusion via removal of extracellular fluid. While other options are secondary benefits, this is the most critical.

Which of the following statements BEST describes the pathophysiology of congenital adrenal hyperplasia (CAH)?
सही उत्तर: घ) Deficient production of cortisol resulting in hyperpigmentation
Decreased cortisol production (option 3) due to adrenal gland dysfunction leads to increased adrenocorticotropic hormone (ACTH), causing hyperpigmentation. The other options represent different endocrine disorders.

A newborn infant presents with respiratory distress, bradycardia, and hypoxemia. Capnography reveals moderate mixed ventilation. What is the MOST appropriate initial intervention?
सही उत्तर: ग) Begin bag-valve-mask ventilation at 40 breaths per minute
Beginning bag-valve-mask ventilation at 40 breaths per minute (option 3) is the standard initial step in neonatal resuscitation for moderate mixed ventilation. Epinephrine and IV fluids are administered concurrently, but ventilation is priority. CPAP is used for milder cases.

Which of the following interventions is MOST appropriate for the initial management of preterm labor at 32 weeks gestation where fetal fibronectin testing is negative and there are no signs of rupture?
सही उत्तर: क) Betamethasone
Betamethasone (option 1) is the standard first-line intervention for accelerating fetal lung maturity in preterm labor. The other options – Misoprostol, Terbutaline, and Magnesium Sulfate – are generally reserved for further management or when betamethasone has failed.

A patient presents with a neurological condition characterized by tremors that worsen with intentional movement (past-pointing on finger-to-nose testing). Which brain structure is most likely affected? (a) Cerebellum. (b) Basal Ganglia. (c) Cerebral Cortex. (d) Spinal Cord.
सही उत्तर: ख) (b) Basal Ganglia.
The correct answer is (a). Intention tremor, particularly one that worsens with voluntary movement like past-pointing, is a classic symptom of cerebellar dysfunction. The cerebellum plays a crucial role in coordinating movement and this type of tremor reflects impaired coordination. Options (b), (c) and (d) are either not directly involved or produce different types of tremors.

During β-oxidation of long-chain fatty acids, which molecule facilitates the transport of these fatty acids into the mitochondrial matrix? (a) Glucose. (b) Citrate. (c) Coenzyme A (CoA). (d) ATP.
सही उत्तर: ग) (c) Coenzyme A (CoA).
The correct answer is (c). Coenzyme A (CoA) acts as an acyl group carrier, binding to the long-chain fatty acid and transporting it into the mitochondrial matrix where β-oxidation occurs. Options (a), (b) and (d) are irrelevant to this process.

Renin is a key enzyme involved in blood pressure regulation. Its secretion is stimulated by decreased renal perfusion pressure. Which of the following describes the primary function of renin? (a) Direct vasoconstriction. (b) Conversion of angiotensinogen to angiotensin I. (c) Increased glomerular filtration rate. (d) Production of red blood cells.
सही उत्तर: ख) (b) Conversion of angiotensinogen to angiotensin I.
The correct answer is (b). Renin catalyzes the first step in the renin-angiotensin system by converting angiotensinogen into angiotensin I, initiating a cascade that ultimately leads to vasoconstriction and increased blood pressure. (a), (c) and (d) are incorrect functions related to renin.
