A 32-year-old man comes to the physician complaining of fever, shortness of breath, and a productive cough that has developed slowly over the past week. He has no other medical history and does not take any medications. His temperature is 38.5°C, blood pressure is 122/78 mmHg, heart rate is 68 beats per minute, respiratory rate is 18 breaths per minute, and oxygen saturation is 98% on room air. There are decreased breath sounds and dullness to percussion over the right lung base. The rest of the physical examination, including cardiac auscultation, is normal. A chest x-ray confirms consolidation of the right lower lobe. What is the most appropriate course of action for this patient?

Physical examination reveals an obese woman in no acute distress. On lung auscultation, there are coarse breath sounds bilaterally but no wheezes or crackles. Chest radiograph is significant for prominent lung markings at the bases.
