Which of the following statements accurately describes the role of the parotid gland? (a) It secretes mucus to protect the esophagus. (b) It is responsible for taste sensation on the lateral aspect of the tongue. (c) It is the primary source of saliva, emptying into the submandibular duct. (d) It produces hormones that regulate gastric acid secretion.
सही उत्तर: घ) (d) It produces hormones that regulate gastric acid secretion.
The parotid gland is the largest salivary gland and its main function is to produce saliva, which empties into the submandibular duct.

A patient presents with symptoms including fatigue, muscle weakness, and elevated creatine kinase (CK) levels. Which biochemical pathway is most likely impaired? (a) Glycolysis (b) The Citric Acid Cycle (c) Oxidative Phosphorylation (d) Gluconeogenesis
सही उत्तर: ग) (c) Oxidative Phosphorylation
Elevated CK levels coupled with symptoms like fatigue and muscle weakness strongly suggest a disruption of the citric acid cycle. This pathway generates significant ATP and also produces products that are released when damaged.

Which of the following best describes the primary function of renin secreted by the juxtaglomerular cells? (a) Stimulating erythropoiesis. (b) Regulating blood pressure via angiotensin II production. (c) Facilitating glucose absorption in the small intestine. (d) Promoting bone mineralization.
सही उत्तर: ख) (b) Regulating blood pressure via angiotensin II production.
Renin is an enzyme secreted by the juxtaglomerular cells of the kidney and plays a crucial role in regulating blood pressure through the renin-angiotensin-aldosterone system (RAAS). This pathway ultimately leads to the production of angiotensin II. Options (a), (c) and (d) represent unrelated functions.

In an adult, the spinal cord typically terminates at what vertebral level? (a) T12 (b) L1 (c) Th9 (d) S3
सही उत्तर: ख) (b) L1
The spinal cord generally terminates at the level of the first lumbar vertebra (L1). This is a well-established anatomical fact. Options (a), (c), and (d) represent other vertebral levels, making them incorrect.

A patient presents with a sudden onset of severe right upper quadrant pain, fever, and chills. Physical examination reveals rebound tenderness and guarding. Laboratory tests show an elevated white blood cell count. What is the most likely diagnosis? (एउटा बिरामी अचानक दायाँ माथिल्लो हातामा तीव्र वेदना, ज्वыр Wheeling र कंपवातको सिकрија प्रस्तुत गर्छ। शारीरिक जाँच गर्दा प्रतिपुष्टि (rebound tenderness) र रक्षात्मक मुद्रा (guarding) देखिएको हुन्छ। प्रयोगशाला परीक्षणहरूले सेतो रक्त कोशिका संख्या बढी देखिन्छ। यो कुन Diagnosis धेरै सम्भावना छ?)
सही उत्तर: ग) C) Pancreatitis.
Option B is correct as the presentation – right upper quadrant pain, rebound tenderness, guarding, fever, and elevated WBC count - strongly suggests acute cholecystitis (inflammation of the gallbladder). Option A describes Hepatitis A’s typical symptoms. Option C represents pancreatitis with similar but distinct presentation features and option D represents ulcer disease.

Which of the following investigations is MOST reliable in confirming the diagnosis of a cholelithiasis (gallstones) with evidence of biliary inflammation? (कपालमा पत्थरी (cholelithiasis) भएको अवस्थामा बिरामीको पेटमा क्यान्सर देखिएको छ। यो निदान पुष्टि गर्न के कुन जाँच विश्वसनीय हुन्छ?)
सही उत्तर: ख) B) Magnetic Resonance Cholangiopancreatography (MRCP).
Option B is correct, as MRCP provides detailed visualization of the biliary tree and its relationship to surrounding structures, allowing for clear identification of gallstones and inflammation. Option A offers less detail. Option C measures pancreatic enzymes which aren't specific for gallbladder pathology and Option D assesses kidney function.

A patient undergoes an upper endoscopy and discovers a pouch-like structure projecting from the terminal ileum. This structure contains gastric mucosa and demonstrates bleeding on biopsy. What is the MOST appropriate initial management? (एउटा बिरामी ह्यापेटोस्कोपबाट पखालेको एउटा भाग टर्मिनल इलियमबाट निस्किएको पत्ता लगाउँछ। यो भागमा पेटको झिल्ली छ र बायोप्सी गर्दा रक्तस्राव देखिएको हुन्छ। यसको लागि कुन प्रारम्भिक व्यवस्थापन उपयुक्त छ?)
सही उत्तर: ग) C) Surgical resection of the affected segment.
Option B is correct as a Meckel's diverticulum with bleeding is most commonly managed with endoscopic submucosal dissection (ESD) to obtain tissue for accurate diagnosis and potentially cure the bleeding. Option A might delay necessary intervention. Option C involves surgical resection, often reserved for complex cases. Option D offers symptomatic relief but doesn’t address the underlying pathology.

A 6-year-old boy presents with projectile vomiting and forceful abdominal contractions. Physical examination reveals a palpable mass in the right upper quadrant. Which of the following is the MOST likely diagnosis? (6 वर्षे बाकसलाई निस्साउने मच्चाहरू र पेटको तीव्र संकुचन हुन्छ। शारीरिक जाँच गर्दा दाहنى माथिल्लो हातामा एक मात्रा महसुस हुन्छ। यो कुनDiagnosis अधिक सम्भावना छ?)
सही उत्तर: ख) B) Pyloric Stenosis.
Option B is correct as pyloric stenosis is the classic presentation in children with forceful vomiting and a palpable mass due to the obstruction by the thickened muscle ring. Option A represents gastroenteritis, which typically presents differently. Option C relates to intussusception, another possible condition but less likely given the described symptoms. Option D describes Crohn’s disease, usually presenting with chronic symptoms.

Which of the following findings is MOST suggestive of acute appendicitis in a patient presenting with right lower quadrant abdominal pain? (कुन विकल्पले तीव्र अपेंडिसाइटिसको लक्षण भढी देखाइन्छ?)
सही उत्तर: ख) B) Palpable McBurney's point.
Option B is correct as palpable McBurney's point is the classical physical finding in acute appendicitis. Option A represents amylase elevation, typically seen in pancreatitis. Option C reflects a general inflammatory response but isn't specific to appendicitis, and Option D describes Murphy's sign, which can be present but isn’t definitive.

A pregnant woman presents with lower abdominal pain and vaginal bleeding. Initial ultrasound findings reveal a small, unruptured ectopic pregnancy within the fallopian tube. Which medication is typically used for initial medical management?
सही उत्तर: ग) Tranexamic acid
Methotrexate is the first-line pharmacological agent utilized in stable cases of unruptured tubal ectopic pregnancies due to its targeted action on rapidly dividing cells. Misoprostol promotes uterine contractions and might cause miscarriage.
