2q: the three most common causes of cardiac tamponade are all except ?

a. neoplastic disease
b. idiopathic pericarditis
c. pericardial effusion
d. cardiac catheterization

answer d . cardiac catheterization is also a cause of cardiac tamponade but is less frequent when compared to the other three mentioned .

b. hypotension
c. jugular venous distension
d. prominent y descent

answer d . prominent x descent and absent y descent,associated with jugular venous distension are characteristic of cardiac tamponade .

5q: all of the following are true about cardiac tamponade except ?

a. it can result by even 200 ml of fluid in the pericardial space , if it develops rapidly
b. in slowly developing effusions more than 2000 ml of fluid can exist in the pericardial space
c. the volume of fluid required to produce cardiac tamponade varies directly with the thickness of the ventricular myocardium
d. the volume of fluid required to produce cardiac tamponade varies directly with the thickness of parietal pericardium

answer d is a false statement . the volume of fluid required to produce cardiac tamponade varies inversely with the thickness of the parietal pericardium .
