MCQ DIASTOLIC DYSFUNCTION

 

Q.All true regarding Diastolic dysfunction  except

a.present in over 25 % of adults

b.primary cause of approx . 50 % of heart failure cases

c.best evaluated with 2D echo with Doppler study

d.the main cause of diastolic dysfunction are the same conditions that result in systolic dysfunction

e.right  atrial volume is a useful indicator of the presence ,chronicity and severity of the left ventricular dysfunction

ANS

e

Upstream ,left atrial function has an important effect on left ventricular filling .Since the left ventricle acts as both conduit and pump ,its ability to transfer blood to the ventricle essentially defines the left ventricular filling .So left   atrial volume is a useful indicator of the presence ,chronicity and severity of the left ventricular dysfunction .

Chronic elevation in  arterial pressure also affect left ventricular relaxation and chamber compliance .

 

MCQ--HRCT

 

Q.All are true regarding HRCT finding except

a.the crazy-paving pattern is specific of   PAP

b.pleural thickening and plaques seen in asbestosis

c.airspace consolidation paralleling chest wall is seen  in Chronic eosinophilc pneumonia

d.mosaic attenuation pattern seen in OB

e.cystic fibrosis shows central and upper lobe bronchiectasis 

ANS .a

The crazy-paving is not specific of PAP .

MCQ --COLON

 

Q.All true regarding colon except

a.in supione postion , transverse and sigmoid colon usually contain greatest amount of gas

b.calibre of colon varies from 3 to 6 cm

c.caecum has the greatest diameter in colon  

d.rupture of sigmoid colon diverticula usually results in free intraperitonal air

e.persistent caecal diameter of 9 to 10 cm or more  indicate of  risk of impending perforation

ANS.d

Rupture of sigmoid colon diverticula usually results in development of retroperitoneal gas  because sigmoid diverticula are frequently oriented toward the sigmoid mesentry .

The sigmoid colon and transverse colon are intraperitoneal structures suspended by the sigmoid mesentry and transverse mesocolon respectively .Ascending colon and descending colon and rectum are fixed retroperitoneal structures .

On upright abdominal radiograph ,air-fluid levels in the bowel are often interpreted as sign of obstruction
