Crescent formation within glomeruli is most frequently associated with which pathological process?
सही उत्तर: घ) Membranoproliferative glomerulonephritis
The characteristic 'lunar crescent' shape in the glomerular basement membrane is a hallmark of post-streptococcal glomerulonephritis, resulting from immune complex deposition and subsequent proliferation of mesangial cells. The other conditions primarily manifest with different types of glomerular changes.

A patient undergoing chemotherapy experiences severe nausea and vomiting. Which of the following medications would be MOST appropriate to manage this symptom?
सही उत्तर: ख) B. Ondansetron.
Ondansetron is a 5-HT3 receptor antagonist specifically used to prevent or treat nausea and vomiting induced by chemotherapy. Morphine is an opioid analgesic and inappropriate for this specific symptom. Prednisolone is a corticosteroid with different applications; bisoprolol is a beta-blocker used for cardiovascular conditions.

Which of the following best describes the primary action of metformin in managing type 2 diabetes mellitus?
सही उत्तर: ख) B. By decreasing hepatic glucose production and improving insulin sensitivity.
Metformin’s primary effect is to reduce glucose production in the liver, thereby lowering blood sugar levels. It also enhances insulin sensitivity, allowing cells to better utilize glucose. Option A is incorrect as metformin does not stimulate insulin release; option C focuses on a mechanism outside its primary action and option D is partially correct but doesn't explain the drug’s overall effect.

The presence of ‘drumstick’ appearance in a bacterial smear suggests which characteristic of the bacteria?
सही उत्तर: ग) C. The bacteria have spherical, terminal spores.
The ‘drumstick’ appearance, observed in bacterial smears, is a characteristic morphological feature of *Bacillus* species due to the presence of large, refractile, spherical spores at their terminals. This is a key diagnostic indicator. Options A and D describe different bacterial characteristics; option B is unrelated.

A patient presents with fever, malaise, and skin lesions consistent with disseminated candidiasis. Which of the following diagnostic tests would MOST likely confirm the diagnosis?
सही उत्तर: ग) C. Culture and sensitivity testing of clinical samples.
Culture and sensitivity testing is crucial for identifying the specific *Candida* species involved in the infection and determining its susceptibility to antifungal medications. While CBC provides valuable information, it doesn’t directly identify fungal infections. Gram stain is useful but often doesn't clearly visualize fungi. Serum protein electrophoresis is related to immune function, not fungal diagnosis.

Mesna is given with cyclophosphamide to prevent: (a) Mucositis (b) Nephrotoxicity (c) Alopecia (d) Bone Marrow Suppression
सही उत्तर: ग) (c) Alopecia
Cyclophosphamide is a potent alkylating agent known to cause significant nephrotoxicity. Mesna acts as a urotoxic metabolite that helps prevent the formation of cyclophosphamide’s toxic metabolites in the bladder, thus reducing the risk of bladder damage and subsequent nephrotoxicity. Option (a) is related to side effects but not the primary preventative measure; options (c) & (d) are other common side effects of cyclophosphamide.

The biological indicator used to test the efficacy of an autoclave is spores of: (a) *Bacillus subtilis* (b) *Geobacillus stearothermophilus* (c) *Staphylococcus aureus* (d) *Pseudomonas aeruginosa*
सही उत्तर: ख) (b) *Geobacillus stearothermophilus*
*Geobacillus stearothermophilus* spores are commonly used as the biological indicator for autoclave validation because they can withstand high temperatures and prolonged exposure to steam. These spores are sensitive to heat and demonstrate the effectiveness of sterilization. The other options are not typically used due to their different temperature tolerances.

Pyridoxine is given with isoniazid to prevent: (a) Neurotoxicity (b) Peripheral Neuropathy (c) Hepatotoxicity (d) Cardiovascular Complications
सही उत्तर: घ) (d) Cardiovascular Complications
Isoniazid is known to cause peripheral neuropathy and hepatotoxicity. Pyridoxine (Vitamin B6) supplementation mitigates the isoniazid-induced hepatotoxicity by acting as a cofactor in the metabolism of isoniazid. Option (a) is incorrect as pyridoxine doesn’t directly prevent neurotoxicity. Option (b) is wrong as pyridoxine doesn’t treat peripheral neuropathy.

Barrett oesophagus is a recognised precursor of: (a) Gastric Ulcers (b) Esophageal Cancer (c) Duodenal Ulcers (d) Peptic Ulcer Disease
सही उत्तर: ख) (b) Esophageal Cancer
Barrett’s oesophagus is a chronic inflammatory condition of the distal oesophagus that develops as a result of prolonged exposure to gastric reflux. It is strongly associated with an increased risk of developing esophageal adenocarcinoma. Option (a) is incorrect because gastric ulcers are typically caused by *Helicobacter pylori* infection or NSAIDs. Option (c) is incorrect as duodenal ulcers have different etiologies.

The presence of ‘ghost cells’ in a histopathological sample suggests which process?
सही उत्तर: ख) Necrosis
Ghost cells are the remnants of neutrophils that have engulfed bacteria and died during an inflammatory response. This indicates phagocytosis followed by cell death – a key feature of necrosis.
