They are distracting us with the alcohol and everything... (((productive cough and fever. started one week ago. (reveals patchy infiltrates) is the most important thing to know in here!!!!

Influenza A virus (The patient has Atypical pneumonia)

I believe that this is B. Mycoplasma pneumoniae.

I think that the person has interstitial pneumonie, with the patchy infiltrates. Also he has consolidation which means he def has pneumoniea. Interstital pneumonia most commonly found in Mycoplasma, Chlamydia pneumoniae, and Legionella.

D) Staph aureus since it causes bronchopneumonia (patchy infiltrates) and abscess (air-fluid level) since he is an alcoholic he probably aspirated the organism.

Default Ans.

D. Staphylococcus aureus
Not to many organisms can create abscesses, and staph aureus can form patchy infiltrates in all lung fields.

I remember being told to drain one of these **** once. Damn painful, wish Id bothered to find out what it was then...I think due it being an abscess its Staph aureus.
(Honestly, is it just me or are the review books going over on alcohol? lol, i guess the key word is "abuse")

My answer is D.
First, among the options listed there is only one bug that can potentially cause destruction in the lung so quickly. I would say the guy got the flu and then developed Staph pneumonia on top of that.
Second, the question clearly describes an abscess in the lung with air/fluid level - a virus wouldn't do that.
