सही: ० / ०
-
A bisferiens pulse (two systolic peaks) is classically felt in:
सही उत्तर: क) Combined aortic stenosis and aortic regurgitation with dominant regurgitation
Pulsus bisferiens occurs in mixed aortic valve disease with predominant regurgitation and in hypertrophic obstructive cardiomyopathy.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
A slow-rising, low-volume pulse (pulsus parvus et tardus) is characteristic of:
सही उत्तर: ख) Aortic stenosis
Fixed obstruction to left ventricular outflow in aortic stenosis produces a small, slowly rising arterial pulse.

-
Intermittent 'cannon' a waves in the jugular venous pulse are characteristic of:
सही उत्तर: ग) Complete (third-degree) heart block
Cannon a waves occur when the right atrium contracts against a closed tricuspid valve; irregular cannon waves indicate atrioventricular dissociation, as in complete heart block.

-
Which antithyroid drug also inhibits peripheral conversion of T4 to T3?
सही उत्तर: ग) Propylthiouracil
Propylthiouracil inhibits thyroid peroxidase and also peripheral 5'-deiodinase; carbimazole/methimazole inhibit only thyroid peroxidase.

-
Proton pump inhibitors such as omeprazole reduce gastric acid by irreversibly inhibiting:
सही उत्तर: ख) H⁺/K⁺-ATPase of parietal cells
PPIs are activated in the acidic canaliculus and covalently inhibit the parietal cell H⁺/K⁺-ATPase, the final step of acid secretion.

-
Quinine and chloroquine are mainly active against which stage of the malaria parasite?
सही उत्तर: घ) Erythrocytic schizonts
Quinine and chloroquine are blood schizonticides; primaquine is needed to kill hepatic hypnozoites of P. vivax and P. ovale.

-
Which inhalational anaesthetic agent has the lowest blood:gas partition coefficient and therefore the fastest induction and recovery?
सही उत्तर: क) Desflurane
A low blood:gas partition coefficient means low blood solubility and rapid equilibration; desflurane (about 0.42) is lower than sevoflurane, isoflurane and halothane.

-
Which antiepileptic drug is a voltage-gated sodium channel blocker that can cause hyponatraemia (SIADH-like) and Stevens–Johnson syndrome, especially in carriers of HLA-B*15:02?
सही उत्तर: ग) Carbamazepine
Carbamazepine blocks Na⁺ channels; it can cause hyponatraemia and, in HLA-B*15:02 carriers (common in South-East Asians), severe SJS/TEN.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Methotrexate exerts its cytotoxic effect mainly by inhibiting:
सही उत्तर: घ) Dihydrofolate reductase
Methotrexate binds dihydrofolate reductase, depleting tetrahydrofolate needed for thymidylate and purine synthesis; 5-FU inhibits thymidylate synthase.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Imatinib, used in chronic myeloid leukaemia, acts by inhibiting:
सही उत्तर: ग) BCR-ABL tyrosine kinase
Imatinib competitively blocks the ATP-binding site of the BCR-ABL fusion tyrosine kinase produced by the Philadelphia chromosome; it also inhibits c-KIT.
