solitary pulmonary nodule
(RR)
what is the importance of a solitary pulmonary nodule?
significant risk of malignancy
(RR)
if a pt has COPD and significant smoking history, and a chest CT shows a 1cm nodule w/ ill-defined margins and a lobular appearance, what is the most appropriate next step?
surgical referral for excision
(RR)
what are the significant pulmonary solid nodule sizes and what are the next steps for each (there are 3 categories)?
<6mm = assess likelihood of malignancy, if high/intermediate –> chest CT at 12 mo
if pt is low-risk, no further f/u required
6-8mm = chest CT at 6 to 12 mo
> 8mm = asses likelihood of malignancy, if low –> chest CT at 3 mo; if high/interm –>biopsy/resection
(RR)

“A transudative pleural effusion is identified after thoracentesis. Which of the following clinical scenarios is most consistent with this type of effusion?
a) 27 y/o F w/ a lupus flare
b) 47 y/o F w/ alcohol use disorder w/ an elevated lipase
