सही: ० / ०
-
Relative bradycardia (pulse–temperature dissociation) and rose spots on the trunk in a febrile patient suggest:
सही उत्तर: क) Typhoid (enteric) fever
Enteric fever classically causes a pulse slower than expected for the fever, rose spots in the second week and hepatosplenomegaly.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Hypokalaemia, metabolic alkalosis and hypercalciuria with normal blood pressure in a young patient, mimicking chronic loop diuretic use, suggest:
सही उत्तर: घ) Bartter syndrome
Bartter syndrome is a defect of the thick ascending limb (like furosemide) with hypercalciuria; Gitelman resembles thiazide use with hypocalciuria and hypomagnesaemia.

-
Type 4 renal tubular acidosis is characterised by:
सही उत्तर: ख) Hyperkalaemia due to hypoaldosteronism or aldosterone resistance
Type 4 RTA, common in diabetic nephropathy, results from low aldosterone or tubular resistance and causes hyperkalaemic normal anion gap acidosis.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Normal anion gap acidosis with hypokalaemia, inability to acidify urine below pH 5.5 and nephrocalcinosis suggests:
सही उत्तर: घ) Distal (type 1) renal tubular acidosis
In distal RTA, the collecting duct cannot secrete H⁺, so urine pH stays above 5.5; hypercalciuria leads to stones and nephrocalcinosis.

-
A patient has Na⁺ 140, Cl⁻ 100 and HCO₃⁻ 10 mmol/L. The anion gap is:
सही उत्तर: क) 30 mmol/L
Anion gap = Na⁺ − (Cl⁻ + HCO₃⁻) = 140 − (100 + 10) = 30 mmol/L, indicating a high anion gap metabolic acidosis.

-
Iron overload due to repeated blood transfusions in thalassaemia major is treated with:
सही उत्तर: ग) Iron chelation therapy such as desferrioxamine or deferasirox
Transfusion-dependent patients cannot undergo phlebotomy, so chelators (desferrioxamine, deferiprone, deferasirox) are used to remove excess iron.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Thrombotic thrombocytopenic purpura is caused by severe deficiency of:
सही उत्तर: घ) ADAMTS13 (von Willebrand factor-cleaving protease)
Without ADAMTS13, ultra-large vWF multimers cause platelet microthrombi, producing thrombocytopenia, microangiopathic haemolysis, neurological signs and renal impairment.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Haemolysis, pancytopenia and venous thrombosis at unusual sites with deficiency of CD55 and CD59 on red cells indicate:
सही उत्तर: क) Paroxysmal nocturnal haemoglobinuria
PNH is an acquired PIGA mutation causing loss of GPI-anchored complement regulators (CD55, CD59), making red cells susceptible to complement lysis; flow cytometry is diagnostic.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Microcytic anaemia with ring sideroblasts in the bone marrow that does not respond to iron suggests:
सही उत्तर: ख) Sideroblastic anaemia
Ring sideroblasts are erythroblasts with iron-laden mitochondria around the nucleus due to defective haem synthesis (e.g. hereditary ALA synthase defect, alcohol, lead, isoniazid).
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
A patient cannot recognise familiar faces despite normal vision. This prosopagnosia results from bilateral lesions of the:
सही उत्तर: घ) Fusiform gyrus of the occipitotemporal cortex
Face recognition depends on the fusiform face area on the inferior occipitotemporal surface; bilateral (or right-sided) damage causes prosopagnosia.
