ABIM IM Practice Test 7

A 47-year-old woman is seen for a follow-up visit 2 weeks after an emergency department evaluation for pleuritic chest pain, which has resolved. CT pulmonary angiography at that visit showed no pulmonary embolism but did show a 7-mm solid, smoothly marginated nodule in the right lower lobe; the lungs were otherwise normal, and there was no lymphadenopathy. She has never smoked, has no history of cancer or occupational exposures, and her family history is negative for lung cancer. She has no cough, hemoptysis or weight loss. No prior chest imaging is available. Vital signs and the physical examination are normal. Which of the following is the most appropriate management of the nodule?
