21. Which of the subsequent marker in the blood is the most reliable indicator of latest hepatitis B- infection?

1. HBsAg
2. lgG anti - HBs
3. lgM anti - HBc
4. lgM anti - HBe
Ans 3

22. The severity of mitral stenosis is clinically best decided by:
1. Length of diastolic murmur.
2. Intensity of diastolic murmur
3. Loudness of 1st heart sound.
4. Split of 2nd heart sound.
Ans 1

23. The risk of developing infective endocarditis is the lowest in a patient with:

1. Small ventricular septal defect
2. Severe aortic regurgitation.
3. Severe mitral regurgitation
4. Large atrial septal defect.
Ans four IE is less in ASD as such, with large pressure ASD pressure difference ¯ so risk is lesser.

24. The severity of mitral regurgitation is decided by all of the subsequent clinical findings except:

1. Presence of mid- diastolic murmur across mitral valve.
2. Wide split of 2nd heart sound.
3. Presence of left ventricular S3 gallop.
4. Intensity of systolic murmur across mitral valve.
Ans one (mid diastolic murmur heard only in MR with MS)

25. Congenital long QT syndrome can lead to:

1. Complete heart block
2. Polymorphic ventricular tachycardia.
3. Acute myocardial infarction.
4. Recurrent supraventricular tachycardia.
Ans 2

26 With reference to bacteroides fragilis all of the subsequent statements are actual other than.

1 It is the most frequent anaerobe isolated from clinical samples.
2. It is not uniformly sensitive to metronidazole.
3. The lipopolysaccharide formed by B. fragills is structurally and functionally various from the conventional endotoxin.
4. Shock and disseminated intravascular coagulation are common in bacteremia due to B. fragilis
Ans four DIC and purpura are less common as LPS lacks biological potency as seen in other gram -ve bacteria.

27. All of subsequent statements are actual regarding Q fever other than.
