Regarding pleural effusion, choose the correct statement:
a) Exudates present at least one of the following three criteria: total protein ratio of pleural fluid to total serum protein greater than 0.5; lactate dehydrogenase (LDH) of pleural fluid greater than two-thirds of the upper limit of normal serum LDH or pleural fluid LDH to serum LDH ratio greater than 0.6.
b) Diagnostic thoracentesis should always be performed as it is essential to define therapeutic intervention.
c) Hemithorax hematothorax is defined by a pleural fluid hematocrit to serum hematocrit ratio greater than 0.8.

A alternativa correta é a letra a) Exsudatos apresentam pelo menos um dos três critérios a seguir: relação proteína total do fluido pleural para proteína sérica total maior que 0,5; desidrogenase láctica (LDH) do fluido pleural maior que dois terços do limite superior da LDH sérica normal ou relação LDH do fluido pleural para LDH sérica maior que 0,6.
