Hypertension with hypokalaemia, low plasma renin and high aldosterone suggests:
सही उत्तर: घ) Primary hyperaldosteronism

The typical electrolyte abnormality in primary adrenal insufficiency (Addison disease) is:
सही उत्तर: ग) Hyponatraemia with hyperkalaemia
Loss of aldosterone causes sodium wasting and potassium retention in Addison disease. Hypernatraemia with hypokalaemia suggests mineralocorticoid excess such as Conn syndrome.

The antithyroid drug preferred during the first trimester of pregnancy is:
सही उत्तर: ख) Propylthiouracil
Propylthiouracil is preferred in the first trimester because carbimazole/methimazole are associated with embryopathy (e.g. aplasia cutis). Radioactive iodine is contraindicated in pregnancy.

The Philadelphia chromosome t(9;22) is characteristic of:
सही उत्तर: ग) Chronic myeloid leukaemia
t(9;22) creates the BCR-ABL fusion tyrosine kinase found in CML, which is targeted by imatinib. Acute promyelocytic leukaemia is associated with t(15;17).

The drug of choice for typical absence seizures in a child without other seizure types is:
सही उत्तर: क) Ethosuximide
Ethosuximide blocks T-type calcium channels in thalamic neurons and is first-line for pure absence seizures. Carbamazepine and phenytoin can worsen absence seizures.

Physostigmine, unlike neostigmine, is preferred for central anticholinergic toxicity because it:
सही उत्तर: ग) Is a tertiary amine that crosses the blood-brain barrier
Physostigmine is lipid soluble and enters the CNS, reversing delirium from atropine-like drugs. Neostigmine is a quaternary compound that does not cross the blood-brain barrier, so it is used for myasthenia and reversing neuromuscular block.
