1. 1. develop a problem list

2. per light’s criteria develop a list of possible etiologies of john’s pleural effusion : for example there are four, these are your differentials until the lab results from the thoracentesis is known. treatment is very different for each. provide a brief description of each differential

thorocentesis was performed:

approximately 2 l of clear yellow pleural ?uid was drained and analyzed for protein, ldh, gram stain, acid fast bacilli (afb) and tb culture, cytology, and microbiological culture. macroscopic and cytological examination of the pleural fluid: small cell count that consisted of a mixture of macrophages and mesothelial cells. there was no evidence of polymorphic leukocytosis. there was no predominance of lymphocytes, there was no evidence of tumor cells present in the pleural ?uid.

microbiology examination of the pleural ?uid was negative for afb. gram stain and culture of the pleural ?uid were also negative.
protein-pleural protein to serum protein level- <0.5

3. what type of pleural effusion is this, and why did john develop it?
whwhat are your treatment options?
