Which of the following pathological features is most strongly associated with chronic myeloid leukemia (CML)? (a) Presence of Negri bodies (b) Philadelphia chromosome translocation (c) Aschoff bodies (d) Round cell stroma
सही उत्तर: ख) (b) Philadelphia chromosome translocation
The Philadelphia chromosome (translocation between chromosomes 9 and 22) is the defining genetic abnormality in CML. The other options represent features of different diseases – Negri bodies are associated with rabies, aschoff bodies with Lyme disease, and round cell stroma can be found in a variety of conditions.

A patient presents with elevated blood levels of creatine kinase (CK). Which of the following conditions is MOST likely? (a) Hypothyroidism (b) Myocardial infarction (c) Addison's disease (d) Cushing’s syndrome
सही उत्तर: ख) (b) Myocardial infarction
Elevated CK levels are commonly associated with muscle damage, such as that caused by a heart attack (myocardial infarction). Options (a), (c), and (d) represent endocrine disorders.

Which of the following best describes the function of mitochondria within a cell? (a) Protein synthesis (b) Lipid storage (c) Energy production through cellular respiration (d) Waste disposal
सही उत्तर: ग) (c) Energy production through cellular respiration
Mitochondria are the powerhouses of the cell, performing oxidative phosphorylation to convert glucose and other fuel molecules into ATP (adenosine triphosphate), the primary energy currency. Options (a), (b), and (d) represent different cellular processes.

The process of gluconeogenesis primarily occurs in which organ? (a) Small Intestine (b) Liver (c) Pancreas (d) Kidney
सही उत्तर: ख) (b) Liver
Gluconeogenesis, the synthesis of glucose from non-carbohydrate precursors, is predominantly carried out by the liver. The small intestine contributes to glucose absorption, the pancreas produces insulin and glucagon, and the kidney plays a role in fluid and electrolyte balance.

In humans, which enzyme is most directly responsible for catalyzing the conversion of glucose to pyruvate during glycolysis? (a) Lactase (b) Hexokinase (c) Amylase (d) Lipase
सही उत्तर: ख) (b) Hexokinase
Hexokinase is the first enzyme in glycolysis, directly catalyzing the phosphorylation of glucose to glucose-6-phosphate. Options (a), (c), and (d) represent enzymes involved in different metabolic pathways – lactose digestion, starch breakdown, and fat metabolism, respectively.

Which of the following statements accurately describes the primary function of the sinoatrial node (SAN)? (a) To filter blood returning to the heart. (b) To initiate and regulate the heartbeat, setting the rhythm for the atria. (c) To increase cardiac output during exercise. (d) To receive electrical signals from the ventricles.
सही उत्तर: ख) (b) To initiate and regulate the heartbeat, setting the rhythm for the atria.
The SAN, also known as the pacemaker of the heart, generates spontaneous electrical impulses that trigger atrial contraction. Options (a), (c), and (d) represent other functions or locations within the cardiovascular system. Option (b) correctly identifies the SAN's role.

A 25-year-old male presents with a painful, leathery skin lesion on his back. Examination reveals no blanching upon pressure. What is the MOST likely diagnosis?
सही उत्तर: ख) Squamous Cell Carcinoma
A burn scar (particularly a large, charred one) that is leathery and blanches poorly indicates squamous cell carcinoma arising from pre-existing tissue damage. Melanomas are often pigmented, basal cell carcinomas typically present as pearly nodules, and sebaceous carcinomas have distinct features. This question tests recognition of skin tumors related to trauma.

A patient has sustained severe acute pancreatitis with resultant edema of the pancreas. Which finding would be MOST indicative of a developing pancreatic pseudocyst?
सही उत्तर: घ) Rapid scarring and fibrosis of the pancreatic tissue
Pseudocysts form when inflammatory debris remains in the pancreas after acute pancreatitis, encapsulated by fibrous tissue. The other options represent stages or outcomes of resolving pancreatitis. This question tests knowledge of complication management following injury.

A 60-year-old male presents with jaundice, weight loss, and palpable gallbladder. Blood tests reveal elevated liver enzymes. Based on Courvoisier’s law, what is the MOST likely diagnosis?
सही उत्तर: ग) Hepatocellular carcinoma
Courvoisier's law (palpable gallbladder with jaundice) strongly suggests biliary obstruction, most commonly cholangiocarcinoma. Cholecystitis typically doesn’t present this way, and hepatocellular carcinoma doesn’t cause significant gallbladder enlargement. This questions focuses on clinical correlation in a surgical scenario.

Which of the following anatomical structures is MOST commonly identified within Calot’s triangle?
सही उत्तर: ग) Portal vein
Calot's triangle encompasses the hepatic artery, cystic duct, and common bile duct. The gallbladder neck is outside this defined space. The portal vein is a major vessel in the abdomen but not contained within the triangle. This question assesses understanding of anatomical landmarks crucial for biliary surgery.
