MRCP2-4139

A 36-year-old woman presents to the respiratory clinic after a CT scan revealed a pulmonary nodule. She was hospitalized two months ago for aspiration pneumonia and received intravenous antibiotics. A chest X-ray showed consolidation on the left side, and she was treated for alcohol withdrawal. After three days, she was discharged with oral antibiotics and community alcohol liaison services. Her GP ordered a repeat chest X-ray six weeks later, which showed persistent consolidation. A CT chest was then performed, revealing a 5 mm pulmonary nodule on the right side. What is the appropriate course of action for investigating or monitoring this nodule?
