Correct answer : A. Occipital lobe is a part of the cerebral cortex
Brainstem consists of midbrain, pons and medulla. Limbic system consists of Hippocampus, Amygdala, Fornix, Mammillary body, Septal nuclei and the limbic lobe (Parahippocampal gyrus, Cingulate gyrus, Dentate gyrus)
Correct answer : B. Loss of proteins
(Repeat AIIMS Nov 2010)
Explanation: In nephrotic syndrome, there is loss of proteins through the glomeruli. This results in hypoalbuminemia and decreased plasma oncotic pressure. Thus fluid moves into the extravascular compartment – development of edema.

Correct answer : B. Stewart-hamilton principle
The volume of blood in the heart and lungs can be measured, by the Stewart-Hamilton principle, as the product of cardiac output and the mean transit time from right atrium to the aortic root.
Ref: http://circ.ahajournals.org/content/33/3/347.abstract
Transpulmonary thermodilution uses the Stewart-Hamilton principle.

Correct answer : c. Shotgun
In firearms, a choke is a tapered constriction of the gun barrel’s bore at the muzzle end, almost always used with shotguns. The purpose is to decrease the spread of the shot in order to gain better range and accuracy.

Correct answer : d. Lipoma of corpus callosum
The bracket sign refers to a radiographic appearance seen with the tubulonodular variety of pericallosal lipoma. It reflects calcification seen at the periphery of the midline lipoma. It is best seen on coronal imaging, and historically was identified on frontal radiographs.
Ref: http://radiopaedia.org/articles/bracket-sign
Tramline calcification is a feature of Sturge-Weber syndrome, and describes the pattern of calcification seen on skull radiology.

In DIC, the levels of coagulation factors are decreased. Whereas in TTP, coagulation factor levels are normal.
Correct answer : A. Sensitivity
A screening test should be sensitive to detect maximum possible cases. Specificity is not as important. After screening, we can apply a confirmatory test with high specificity.
