Incorrect. The peripheral blood smear shows schistocytes. This is non- specific. Schistocytes can occur in any condition that is associated with Microangiopathic Hemolytic Anemia (MAHA). MAHA can be seen in TTP, HUS, DIC, HELLP syndrome and malignant hypertension. +
''Candida albicans'' is responsible for thrush, which is distinct from hairy leukoplakia. Thrush can be mechanically disturbed by scraping with tongue depressor whereas hairy leukoplakia cannot. +
Lymphocytic infiltrates may be observed in brain biopsies of patients with encephalitis. Encephalitis is characterized by the presence of fever and a more rapid onset of symptoms. +
'''Incorrect''' : Joint fluid culture alone is positive only in 50% of individuals with gonococcal arthritis. +
'''Incorrect'''-Polyuria and polydipsia are not features of SIADH although it results in hyponatremia. Besides low serum osmolality, they have inappropriately high urine osmolality. +
'''Incorrect'''-Frequent neck examinations is not sensitive enough to diagnose early medullary thyroid carcinoma. +
'''Incorrect'''-Low serum potassium will guide you to arrive at the diagnosis, but can not be specific for the diagnosis since it may be normal in milder forms of primary hyperaldosteronism. +

'''Incorrect''' : Panic attacks can present in a similar way. However high blood pressure in one of the previous attack favors the diagnosis of pheochromocytoma. +
'''Incorrect''' : MRI is done while the patient is on alpha blockers. MRI is more sensitive for extraadrenal tumours. MRI can also differentiate malignant pheochromcytoma. +
'''Incorrect''' : Removal of alpha blockade could be done, but it is never going to be as effective as crystalline solution in the management of hypotensive crisis. +
'''Correct''' : Once the patient is adequately hydrated with isotonic saline infusion, next step would be to save kidney’s by alkalizing urine with adequate bicarbonate infusion as the patient’s creatine kinase levels are very high. +
