Q 1,2,3,4,5,8,13-the answers you mentioned are correct.refer anantnarayan.
Q6 see KDT,i am also not sure about hepatitis.its given as liver dysfunction.but hypotension is mentioned.so,most probably that's the correct answer.
Q10-correct ans,see granulomatous inflammation in robbins
Q11-correct ans,robbins
Q12-B4,see robbins,inflammation chap
rest i am not sure

Plasma cell pneumoni is caused by-
a)Friedlander's bacillus
b)Streptococcus
c)CMV
d)P.carinii.......A???

On lung sections stained with hematoxylin and eosin, the alveoli are filled with a typical foamy, vacuolated exudate. Severe disease may include interstitial edema, fibrosis, and hyaline membrane formation. The host inflammatory changes usually consist of hypertrophy of alveolar type II cells, a typical reparative response, and a mild mononuclear cell interstitial infiltrate. Malnourished infants display an intense plasma cell infiltrate that gave the disease its early name: interstitial plasma cell pneumonia
